The present invention relates generally to monitoring a subject in her or his bed, typically in a home setting. Specifically, some applications of the present invention relate to controlling a device or generating an alert or notification in response to the subject's sleep state, and/or for automatically identifying a state of a female subject's menstrual cycle, and/or whether the female subject is in a pregnant or non-pregnant state.
There is great variation in the lengths of women's menstrual cycles. It is often the case that women would like to know the current phase of their menstrual cycle. Of particular interest to many is knowledge of when they are in the “fertile window” which occurs from approximately five days before ovulation until two days after ovulation. Typically, urine tests, calendar-based methods, and symptoms-based methods (in which parameters such as cervical mucus, cervical position, and basal body temperature are measured) are used for such determinations.
Quality and duration of sleep plays an important role in overall physical and psychological wellbeing. Unfortunately, many subjects have difficulty falling or staying asleep. In some cases, subjects' sleep may be disrupted by ambient noise from home appliances or other household members.
In accordance with some applications of the present invention, a sensor monitors a female subject and generates a sensor signal in response to the monitoring. A computer processor receives the sensor signal and, in response to analyzing the sensor signal, automatically identifies a menstrual state of the subject, and/or a pregnancy state of the subject (i.e., whether the subject is in a pregnant or a non-pregnant state). For example, the computer processor may identify an aspect of the sensor signal, such as a cardiac-related aspect of the sensor signal, and/or a respiration-related aspect of the sensor signal, and may perform the identification of the subject's state in response thereto. In response to determining the subject's menstrual state, and/or pregnancy state, the computer processor generates an output.
Typically, the sensor performs monitoring of the subject without contacting the subject or clothes the subject is wearing, and/or without viewing the subject or clothes the subject is wearing. For example, the sensor may perform the monitoring without having a direct line of sight of the subject's body, or the clothes that the subject is wearing. Further typically, the sensor performs monitoring of the subject without requiring subject compliance (i.e., without the subject needing to perform an action to facilitate the monitoring that would not have otherwise been performed). It is noted that, prior to the monitoring, certain actions (such as purchasing the sensor and placing the sensor under the subject's bed) may need to be performed by the subject. The term “without requiring subject compliance” should not be interpreted as excluding such actions. Rather the term “without requiring subject compliance” should be interpreted as meaning that, once the sensor has been purchased, placed in a suitable position and activated, the sensor can be used to monitor the subject (e.g., to monitor the subject during repeated monitoring sessions), without the subject needing to perform any actions to facilitate the monitoring that would not have otherwise been performed.
Typically, the sensor is disposed on or within the subject's bed, and configured to monitor the subject automatically, while she is in her bed. For example, the sensor may be disposed underneath the subject's mattress such that the subject is monitored while she is lying upon the mattress, and while carrying out her normal sleeping routine, without the subject needing to perform an action to facilitate the monitoring that would not have otherwise been performed.
For some applications, the sensor is a non-temperature sensor (i.e., the sensor is not configured to measure a temperature of the subject). Typically, the computer processor is configured to identify the subject's menstrual state and/or pregnancy state without determining a temperature of the subject.
In response to determining the subject's menstrual state and/or pregnancy state, the computer processor generates an output. For example, the computer processor may drive an output device (e.g., a monitor, or the screen of a tablet device or a smartphone) to display (or otherwise output) an output that is indicative of the identified menstrual state and/or pregnancy state. Alternatively or additionally, the processor may drive an output device (e.g., a monitor, or the screen of a tablet device or a smartphone) to display (or otherwise output) an output that is indicative of a recommended action to be taken by the user (e.g., “intercourse is recommended within the next 48 hours”), based upon the identified menstrual state and/or pregnancy state. Alternatively or additionally, the processor may drive a device (such as a room-climate-regulation device) in the subject's bedroom to perform a function or to change a parameter of its functioning in response to the identified menstrual state and/or pregnancy state.
Applications of the present invention include apparatus for controlling the playing of music for a subject who is sleeping or is trying to fall asleep. In response to historical data obtained from the subject and to the monitoring of the subject by a sensor, the apparatus controls a property (e.g., a frequency) of the music, e.g., in order to facilitate the slowing of the subject's heart rate and thus help the subject fall asleep.
Applications of the present invention also include apparatus for facilitating the provision of care by a care-provider for a care-receiver. The apparatus monitors sleep of the care-provider and sleep of the care-receiver, and drives an alerting device to wake the care-provider at an opportune time for care-giving, e.g., when both parties are in a light stage of sleep.
Applications of the present invention also include apparatus and methods for facilitating a subject's sleep, such as by controlling noisy home appliances in response to the subject's stage of sleep, and/or by activating a white-noise generator or a noise-cancelation device when a noisy home appliance is activated.

The present invention will be more fully understood from the following detailed description of applications thereof, taken together with the drawings, in which:
Reference is made to
Subject-monitoring apparatus 20 comprises a sensor 22 (e.g., a motion sensor) that is configured to monitor subject 24. Sensor 22 may be a motion sensor that is similar to sensors described in U.S. Pat. No. 8,882,684 to Halperin, which is incorporated herein by reference. The term “motion sensor” refers to a sensor that senses the subject's motion (e.g., motion due to the subject's cardiac cycle, respiratory cycle, or large-body motion of the subject), while the term “sensor” refers more generally to any type of sensor, e.g., a sensor that includes an electromyographic sensor and/or an imaging sensor.
Typically, sensor 22 includes a sensor that performs monitoring of the subject without contacting the subject or clothes the subject is wearing, and/or without viewing the subject or clothes the subject is wearing. For example, the sensor may perform the monitoring without having a direct line of sight of the subject's body, or the clothes that the subject is wearing. Further typically, the sensor performs monitoring of the subject without requiring subject compliance (i.e., without the subject needing to perform an action to facilitate the monitoring that would not have otherwise been performed). It is noted that, prior to the monitoring, certain actions (such as purchasing the sensor and placing the sensor under the subject's mattress) may need to be performed. The term “without requiring subject compliance” should not be interpreted as excluding such actions. Rather the term “without requiring subject compliance” should be interpreted as meaning that, once the sensor has been purchased, placed in a suitable position and activated, the sensor can be used to monitor the subject (e.g., to monitor the subject during repeated monitoring sessions), without the subject needing to perform any actions to facilitate the monitoring that would not have otherwise been performed.
For some applications, sensor 22 is disposed on or within the subject's bed, and configured to monitor the subject automatically, while she is in her bed. For example, sensor 22 may be disposed underneath the subject's mattress 26, such that the subject is monitored while she is lying upon the mattress, and while carrying out her normal sleeping routine, without the subject needing to perform an action to facilitate the monitoring that would not have otherwise been performed.
A computer processor 28, which acts as a control unit that performs the algorithms described herein, analyzes the signal from sensor 22. Typically, computer processor 28 communicates with a memory 29. For some applications, computer processor 28 is embodied in a desktop computer 30, a laptop computer 32, a tablet device 34, a smartphone 36, and/or a similar device that is programmed to perform the techniques described herein (e.g., by downloading a dedicated application or program to the device), such that the computer processor acts as a special-purpose computer processor. For some applications, as shown in
For some applications, the subject (or another person, such as a care-giver) communicates with (e.g., sends data to and/or receives data from) computer processor 28 via a user interface device 35. As described, for some applications, computer processor is embodied in a desktop computer 30, a laptop computer 32, a tablet device 34, a smartphone 36, and/or a similar device that is programmed to perform the techniques described herein. For such applications, components of the device (e.g., the touchscreen, the mouse, the keyboard, the speakers, the screen) typically act as user interface device 35. Alternatively, as shown in
For some applications, user interface includes an input device such as a keyboard 38, a mouse 40, a joystick (not shown), a touchscreen device (such as smartphone 36 or tablet device 34), a touchpad (not shown), a trackball (not shown), a voice-command interface (not shown), and/or other types of user interfaces that are known in the art. For some applications, the user interface includes an output device such as a display (e.g., a monitor 42, a head-up display (not shown) and/or a head-mounted display (not shown), such as Google Glass®), and/or a different type of visual, text, graphics, tactile, audio, and/or video output device, e.g., speakers, headphones, smartphone 36, or tablet device 34. For some applications, the user interface acts as both an input device and an output device. For some applications, the processor generates an output on a computer-readable medium (e.g., a non-transitory computer-readable medium), such as a disk, or a portable USB drive.
Reference is now made to
In a fourth step 56, the computer processor generates an output in response to the identified menstrual state and/or pregnancy state. For example, the computer processor may drive an output device (e.g., as described above) to display (or otherwise output) an output that is indicative of the identified menstrual state and/or pregnancy state (for example, a smartphone application, running on smartphone 36, may be driven to display such an output). Alternatively or additionally, the processor may drive an output device (e.g., as described above) to display (or otherwise output) an output that is indicative of a recommended action to be taken by the user (e.g., “intercourse is recommended within the next 48 hours”), based upon the identified menstrual state and/or pregnancy state. Alternatively or additionally, the processor may drive a device (such as a room-climate-regulation device 44) in the subject's bedroom to perform a function or to change a parameter of its functioning in response to the identified menstrual state and/or pregnancy state, as described in further detail hereinbelow.
For some applications, sensor 22 is a non-temperature sensor (i.e., the sensor is not configured to measure a temperature of the subject). (For some of the applications described hereinbelow, sensor 22 may include temperature-sensing capabilities.) Typically, the computer processor is configured to identify the subject's menstrual state and/or pregnancy state without determining a temperature of the subject.
Reference is now made to
Based upon the above-noted observations, in some applications, step 52 of
In some applications, the computer processor uses the average heart rate of a previous sleeping session as a baseline, and in response to the identified average heart rate being greater than this baseline, the computer processor identifies the recent ovulation or predicts the upcoming ovulation.
The relatively flat portion of the plot of
Typically, if the subject becomes pregnant, the heart rate of the subject remains elevated, relative to the pre-ovulation heart rate. (Although, as noted above, typically the heart rate of the subject may increase shortly before ovulation. Therefore, in this context, the “pre-ovulation heart rate” refers to the normal heart rate of the subject, prior to the increase.) If the subject does not become pregnant, on the other hand, the heart rate of the subject drops back to its pre-ovulation level. Hence, in some applications, the computer processor performs step 54 of
Typically, the post-ovulation baseline heart rate to which the average heart rate is compared is based on a previously-identified heart rate from the same menstrual cycle as the currently-identified heart rate. For example, the computer processor may identify the post-ovulation baseline heart rate in response to a heart rate of the subject that was identified less than fourteen days prior to identifying the currently-identified heart rate.
As noted above, alternatively or additionally to identifying a cardiac-related aspect of the sensor signal, the computer processor may identify a respiration-related aspect of the sensor signal, such as a respiratory rate of the subject. (For example, the computer processor may identify an average respiratory rate of the subject during a sleeping session of the subject.) In general, respiratory rate, like heart rate, typically rises to an elevated level at around the time of ovulation, and typically remains at the elevated level only if the subject becomes pregnant. Hence, the computer processor may perform step 52 of
In some applications, the identified aspect of the sensor signal includes a heart rate variability (HRV) signal, and the computer processor performs step 54 of
In some cases, alternatively or additionally to knowing that she is in her late follicular phase, a subject may wish to know her anticipated date of ovulation. Thus, in some applications, the computer processor performs step 54 of
For some applications, in response to determining the current stage of the subject's menstrual cycle (e.g., using techniques described herein), the computer processor generates an output indicative of when it is advisable for the subject to have intercourse such as to increase her chances of conceiving a baby. Furthermore, there is evidence that having intercourse close to ovulation or shortly thereafter (e.g., on the day of ovulation or subsequent thereto) favors conceiving a male baby, while having intercourse several days (e.g., 2-5 days) prior to ovulation favors conceiving a female baby. Therefore, for some applications, the subject (or a person related to the subject, such as the subject's partner) communicates an input to computer processor 28 (e.g., via user interface device 35) that is indicative of a desire to have a child of a given gender. In response to determining the current stage of the subject's menstrual cycle (e.g., using techniques described herein), the computer processor generates an output indicative of when it is advisable for the subject to have intercourse such as to increase her chances of conceiving a baby of the desired gender.
In some applications, the computer processor identifies that the subject is likely to experience premenstrual syndrome (PMS) within a given period of time, e.g., in more than 0.5 days and/or less than three days. For example, the computer processor may predict the upcoming episode of PMS in response to the HRV signal (e.g., in response to the power spectrum of the HRV signal).
In the context of the claims and description of the present application, a phrase such as “within a given amount of time” or “within a given period of time” includes within its scope different levels of specificity. For example, for a prediction that the subject will likely ovulate within two days, the computer processor may generate a less specific output such as “You will likely ovulate within two days,” or a more specific output such as “You will likely ovulate in approximately 1.5 days.” Similarly, a phrase such as “in less than three days” includes within its scope different levels of specificity. For example, for a prediction that PMS will likely occur in less than three days, the computer processor may generate a less specific output such as “You will likely experience PMS in less than three days,” or a more specific output such as “You will likely experience PMS in approximately two days.”

For example,
In some applications, the computer processor continually improves the learned rule, based on feedback from the user. For example, if the computer processor identified that the subject was pregnant, and the identification was later found to be incorrect, the subject may report the incorrect identification to the computer processor, and the computer processor may modify the rule accordingly.
For some applications, computer processor is configured to incorporate non-subject-specific data into a machine learning-algorithm, in order to identify the subject's menstrual state and/or pregnancy state, generally in accordance with techniques described herein. For example, the computer processor may be configured to receive data (e.g., via a network) regarding measured parameters of other females, and the corresponding menstrual state(s) and/or pregnancy state(s) of those females. The computer processor is configured to use these data as additional inputs in a machine-learning algorithm, in order to identify the subject's menstrual and/or pregnancy state.
As shown in
In general, learning step 60 may be applied to any of the menstrual state and/or pregnancy state identification applications described hereinabove, as well as to other similar applications. For example:
(i) The subject may provide one or more inputs indicative of whether she is pregnant, and the computer processor may identify the aspect of the sensor signal associated with each of the inputs. The computer processor may then learn a pregnancy-identification rule in response to the inputs and the identified aspects. The pregnancy-identification rule may then be used to identify, in response to the current sensor signal, whether the subject is pregnant.
(ii) The subject may provide one or more inputs indicative of the current phase of her menstrual cycle, and the computer processor may identify the aspect of the sensor signal associated with each of the inputs. The computer processor may then learn a phase-identification rule, and/or an ovulation-prediction rule, in response to the inputs and the identified aspects. The learned rule may then be used, in response to the current sensor signal, to identify the current phase of the subject's menstrual cycle, and/or predict an upcoming ovulation.
(iii) The subject may provide one or more inputs indicative of an occurrence of PMS, and the computer processor may identify the aspect of the sensor signal associated with each of the inputs. The computer processor may then learn a PMS-prediction rule in response to the inputs and the identified aspects. The PMS-prediction rule may then be used to predict, in response to the current sensor signal, an upcoming occurrence of PMS.
Reference is again made to
In some applications, the computer processor is further configured, in response to analyzing the sensor signal, to identify a sleep stage of the subject during the subject's sleeping session. (To identify the sleep stage of the subject, the computer processor may utilize techniques described in US 2007/0118054 to Pinhas (now abandoned), which is incorporated herein by reference.) The identification or prediction of the subject's condition is then performed in response to an aspect of the sensor signal that is exhibited while the identified sleep stage is a particular sleep stage, and substantially not in response to any aspect of the sensor signal that is exhibited while the identified sleep stage is not the particular sleep stage.
For example, the computer processor may substantially restrict the analysis to slow-wave (i.e., deep) sleep, i.e., the computer processor may identify or predict the subject's condition substantially only in response to an aspect of the sensor signal that was exhibited during slow-wave sleep. In some cases, it may be advantageous to substantially exclude REM sleep from the analysis. For example, during REM sleep, dreaming of the subject may cause changes in heart rate which, with respect to the identification of the subject's menstrual stage, constitute unwanted “noise”. On the other hand, in some applications, the analysis is substantially restricted to the REM sleep stage. For example, the HRV signal during REM sleep may, in some cases, be particularly indicative of the subject's current or upcoming condition.
While the scope of the present invention includes using data from the particular sleep stage, to the complete exclusion of all other sleep stages, the scope of the present invention also includes using data from sleep stages other than the particular sleep stage, to a certain limited extent. This is indicated, in the relevant portions of the claims and description of the present application, by the word “substantially.” In particular, “substantially not in response to any aspect of the sensor signal that is exhibited while the identified sleep stage is not the particular sleep stage” means that even if data that is not from the particular sleep stage is used for the analysis, this data is used to a relatively small extent, such that it does not have a significant influence on the outcome of the analysis. For example:
(i) For a non-numeric output (e.g., an output indicative of whether the subject is pregnant), or a numeric output having a relatively small number of possible values, the “substantially excluded” data might not change the outcome in more than 5% of cases. In other words, in at least 95% of cases, the computer processor would output the same value, regardless of whether the substantially excluded data is used for the analysis.
(ii) For a numeric output having a relatively large number of possible values (e.g., an output that is generally continuous-valued, such as an expected amount of time until ovulation), the substantially excluded data might not change the value of the output by more than 5%. For example, if, when completely excluding the data, a value of 2.0 days were output, including the data in the analysis would not change the output by more than 0.1 days.
It is noted that the scope of the present invention includes restricting the analysis to more than one sleep stage. For example, the analysis may be restricted to all sleep stages except for REM sleep.
In some applications, in response to analyzing the sensor signal, the computer processor identifies the end of the chronologically-first or chronologically-second sleep cycle of the subject during the sleeping session. (For example, to identify the end of a sleep cycle, the computer processor may utilize techniques described above with respect to sleep-stage identification.) In such applications, alternatively or additionally to substantially restricting the analysis to a particular sleep stage, the computer processor may substantially restrict the analysis to data collected after the end of the chronologically-first or chronologically-second sleep cycle. (In this context, as before, the word “substantially” is to be understood to indicate that the computer processor does not necessarily completely exclude from the analysis data that is collected outside the specified portion of the sleeping session.) The inventors have observed that in some cases, data collected during the first and/or second sleep cycle may contain “artifacts,” i.e., the data may reflect activities (e.g., eating) that the subject performed before going to sleep, and may thus “mislead” the computer processor. Hence, by substantially excluding the first and/or second sleep cycle from the analysis, these artifacts are substantially filtered out. Alternatively or additionally, the computer processor may substantially restrict the analysis to data collected at least a particular amount of time from the beginning of the sleeping session. For example, the computer processor may substantially exclude from the analysis any data that is collected less than two hours from the beginning of the sleeping session.
Alternatively or additionally to the above, in some applications, the computer processor may, in response to analyzing the sensor signal, determine a level of motion of the subject while the subject sleeps. In such applications, the computer processor may substantially restrict the analysis to data collected while the level of motion does not exceed a threshold. (Again, the word “substantially” is to be understood as explained above.) In this manner, motion artifacts in the sensor signal are substantially excluded from the analysis.
The scope of the present invention includes “substantial exclusion” of the first or second sleep cycle of the subject in any relevant context. In other words, the computer processor may identify or predict any physiological condition (i) in response to an aspect of the sensor signal that is exhibited following the end of the chronologically-first or chronologically-second sleep cycle, and (ii) substantially not in response to any aspect of the sensor signal that is exhibited before the end of the chronologically-first or chronologically-second sleep cycle. Furthermore, the analysis in which the first and/or second sleep cycle are excluded may be in response to a signal from any type of sensor, including those sensors that require compliance of the subject to monitor the subject.

In response to the analyzing, control unit 28 controls a property (e.g., the content, genre, volume, frequency, and/or phase-shift) of a sound signal, and drives a speaker 70 to play the sound signal. Typically, as described hereinbelow, the property of the sound signal is controlled such as to help the subject fall asleep or remain asleep.
For example, if the subject is trying to fall asleep, the control unit may select a sound signal of the “relaxing nature sounds” genre, and may further select the content of the signal to be the sound of waves hitting the seashore. The control unit may further set the frequency of the sound signal (e.g., the frequency of the waves) to an offset less than the subject's current heart rate or respiratory rate, in order to facilitate slowing of the subject's heart rate and/or respiratory rate. In some applications, the control unit controls the offset, in response to analyzing the sensor signal; for example, as the heart rate of the subject approaches a target “relaxed” heart rate, the control unit may reduce the offset, such that the frequency of the sound signal is very close to or identical with the subject's heart rate. As the subject begins to fall asleep, the control unit may reduce the volume of the sound signal.
In some applications, the control unit controls a phase-shift of the sound signal with respect to a cardiac signal and/or a respiratory signal of the subject. For example, the control unit may cause the sound of a wave hitting the seashore to occur a given amount of time (e.g., 300 milliseconds) before or after each heartbeat of the subject, or a given amount of time (e.g., 1 second) after each expiration of the subject.
In some applications, the control unit ascertains that the subject is trying to fall asleep, at least in response to analyzing the sensor signal. For example, by analyzing the sensor signal, the control unit may ascertain that the subject is awake and is exhibiting a large amount of movement indicative of restlessness in bed. Alternatively or additionally, the ascertaining is in response to one or more other factors, such as a signal from a light sensor that indicates a low level of ambient light in the room, and/or the time of day. In response to ascertaining that the subject is trying to fall asleep, the control unit controls the property of the sound signal, as described hereinabove.
In some applications, by analyzing the sensor signal, the control unit ascertains a sleep stage of the subject, and controls the property of the sound signal in response to the ascertained sleep stage. For example, in response to ascertaining that the subject has entered a slow-wave (i.e., deep) sleep stage, the volume of the sound signal may be reduced to a relatively low level (e.g., zero). (In identifying a sleep stage of a subject, as described throughout the present application, the control unit may use one or more of the techniques described in (a) US 2007/0118054 to Pinhas (now abandoned), (b) Shinar et al., Computers in Cardiology 2001; Vol. 28: 593-596, and (c) Shinar Z et al., “Identification of arousals using heart rate beat-to-beat variability,” Sleep 21(3 Suppl):294 (1998), each of which is incorporated herein by reference.)
Typically, the control unit controls the property of the sound signal further in response to a historical physiological parameter of the subject that was exhibited in response to a historical sound signal. For example, the control unit may “learn” the subject's typical responses to particular sound-signal properties, and control the sound signal in response thereto. Thus, for example, if the subject has historically responded well to a “relaxing nature sounds” genre, but less so to a “classical music” genre, the control unit may select the former genre for the subject. To determine whether the subject has historically responded well to particular properties of the sound signal, the control unit looks at some or all of historical physiological parameters such as a quality of sleep, a time-to-fall-asleep, a heart-rate-variability, a change in heart rate, a change in respiratory rate, a change in heart-rate-variability, a change in blood pressure, a rate of change in heart rate, a rate of change in respiratory rate, a rate of change in heart-rate-variability, and a rate of change in blood pressure.
In some applications, the control unit controls the frequency of the sound signal by synthesizing the sound signal, or by selecting a pre-recorded sound signal that has the desired frequency; in other words, the control unit selects the content of the signal, without the user's input. In other applications, the control unit selects content of the sound signal in response to a manual input, e.g., an input entered via user interface device 35 (

In some applications, e.g., with an infant subject, the control unit drives a vibrating or rocking mechanism 80 by sending a control signal to the mechanism, alternatively or additionally to driving the speaker to play the sound signal. For example, in response to analyzing the sensor signal, the control unit may ascertain that the infant is not sleeping. In response to the ascertaining, the control unit may control a device such as the Lullabub Cot Rocker™ by Babyhugs Pty of Mermaid Beach, Australia, in order to help the infant fall asleep. In some applications, the controlling of the vibrating or rocking mechanism is also in response to historical sleep-related data of the subject. For example, if the infant has historically responded well to vibrations at a particular frequency, the control unit may select that particular frequency. (The historical sleep-related data may include any of the parameters described above, such as time-to-fall-asleep or heart-rate-variability.)
In some applications, in response to the subject awakening prematurely, the control unit “recreates” the environment that originally helped the subject fall asleep. For example, if a particular sound and/or rocking setting helped the infant fall asleep at the beginning of the night, the same setting may be used to help the infant fall asleep, upon the infant waking up prematurely.
In some applications, the control unit performs a “sweep” (or “optimization routine”) over various sound and/or vibration and/or rocking settings, in order to learn which settings are more conducive to sleep of the subject, relative to other settings. For example, over the course of one or more sleeping sessions, the control unit may vary a parameter such as a sound frequency, a sound amplitude, a vibration frequency, a vibration amplitude, a rocking frequency, or a rocking amplitude. By analyzing the sensor signal, the control unit identifies a value of the parameter that is more conducive to sleep of the subject, relative to other values. Subsequent to the learning, the control unit sets the selected parameter to the identified value. The sweep may be performed before every sleeping session, or alternatively, at less frequent intervals, depending on how well the subject is responding to the identified “optimal” settings.

A typical scenario, in which care-provider 112 is a mother and care-receiver 114 is a newborn baby, is depicted in
Control unit 28 is also configured to handle complex scenarios in which identifying an “optimal alerting time” is more difficult, such as where the sleep cycles of the two parties are generally not in synch with each other. (For example, one of the parties may typically be in a deep sleep whenever the other party is in a light sleep.) To handle these scenarios, the control unit may make use of historical sleep-related data of the care-provider and/or the care-receiver, e.g., using techniques as described hereinbelow. For example, if the historical data shows that the care-provider typically takes longer to fall asleep than the care-receiver, the control unit may give greater weight to the sleep stage of the care-provider, relative to the sleep stage of the care-receiver. (Thus, for example, the control unit may alert the care-provider if the care-provider is awake, even if the care-receiver is in a deep sleep.) The control unit may also use the historical data to predict upcoming changes. For example, the control unit may predict that the deep-sleeping party will, within a given period of time, move into an REM sleep-stage or a light sleep-stage, while the other party will remain in a light sleep-stage. In response to this prediction, the control unit may withhold the alert for the given period of time, rather than unnecessarily disturb the deep-sleeping party. Statistical averages based on age, gender, etc. may be used, alternatively or additionally to the historical data.

Sensor 22 is used to monitor sleep of subject 24 and to generate a signal in response thereto. By analyzing the signal, control unit 28 ascertains a sleep stage of the subject, and in response thereto, controls the home appliance. Sensor 22 and control unit are typically generally similar to sensor 22 and control unit 28 described hereinabove. Typically, a method 120 (depicted in
In some applications, the home appliance is controlled in response to historical sleep-related data of the subject. For example, the control unit may “learn” the subject's tolerance to noise, and control the appliance in response thereto. Thus, for example, if the control unit learns that the subject is particularly tolerant to noise, the control unit may activate the appliance even if the subject is not in a deep sleep.

In some cases, the control unit may increase a noise level of the room-climate-regulation device in response to the identified sleep stage not being a slow-wave (i.e., deep) sleep stage. A subject who is awake or is sleeping lightly may desire “white noise” in order to drown out other ambient noise and/or lull the subject to sleep; in such cases, the control unit increases the noise level of the room-climate-regulation device. Conversely, the control unit may decrease the noise level in response to the identified sleep stage being a slow-wave sleep stage, since a deep-sleeping subject typically requires less white noise.
In other cases, the control unit may increase the noise level of the room-climate-regulation device (e.g., by turning the device on) in response to the identified sleep stage being a slow-wave sleep stage, and/or decrease the noise level of the room-climate-regulation device (e.g., by turning the device off) in response to the identified sleep stage not being a slow-wave sleep stage. This may be appropriate, for example, if the subject is easily disturbed by noise, and prefers that the room-climate-regulation device makes noise only when the subject is in a deep sleep. (In other words, the subject may want to defer the regulation of temperature until the subject is sleeping deeply.)
In some applications, the control unit is configured to control the noise-emission of the room-climate-regulation device further in response to an ambient noise level. For example, the control unit may increase the white noise emission of the device only if the level of ambient noise is greater than a threshold.
In some applications, the apparatus shown in
In some applications, the control unit controls the frequency and/or phase-shift of the emitted noise further in response to the identified sleep stage of the subject. For example, in response to the subject being awake, the control unit may set the frequency of the speed oscillations of the fan (and hence, the frequency of the emitted noise) to be slightly less than the heart rate of the subject, in order to help the subject fall asleep. In general, apparatus 20 as shown in
Studies show that dynamically regulating the temperature of a subject's sleep environment may improve the subject's sleep quality. For example, maintaining a steady temperature may increase the slow-wave-sleep (SWS) ratio, and cooling the bed during rapid-eye-movement (REM) sleep may increase the REM sleep share rate. In some applications, the control unit is configured, in response to the identified sleep stage, to control a temperature setting of the room-climate-regulation device. For example, the control unit may be configured to lower the temperature setting of the room-climate-regulation device in response to the identified sleep stage being an REM sleep stage. Examples of room-climate-regulation devices the temperatures of which may be controlled include air-conditioning units (e.g., room-climate-regulation device 170 as shown in
In some applications, the control unit is configured, by analyzing the sensor signal, to identify an indication of a body temperature of the subject, and/or ascertain that the subject is uncomfortable with the current ambient temperature. The control unit then controls the temperature setting in response thereto. For example, the control unit may identify a tremor component of the signal, i.e., a component of the signal indicative of shivering of the subject, and in response thereto, raise the temperature setting of the room-climate-regulation device. Alternatively or additionally, the control unit may control a setting (e.g., a temperature setting) of the room-climate-regulation device in response to identifying changes in parameters of the subject from their baseline values. Such parameters include motion of the subject, respiratory rate, respiratory patterns, respiration amplitude, respiration-cycle variability, heart rate, heart rate variability, heartbeat amplitude, pulse transfer time, left ventricular ejection time, and vasoconstriction. In some applications, the control unit controls the temperature setting of the room-climate-regulation device irrespective of the sleep stage of the subject.
In some applications, control unit 28 is adaptive to a particular subject, in that the control unit “learns” from previous responses of the subject to changes in the noise level or temperature setting of the room-climate-regulation device. For example, the control unit may modify the magnitude or timing of the change in response to a previous change not having been fully effective, or in response to a previous change having been disruptive to the subject's sleep.
Reference is now additionally made to
(a) As the subject is falling asleep (i.e., is in a falling-asleep stage, prior to sleep), the heat should be set to a high setting.
(b) As the subject begins to sleep (i.e., is in a beginning-sleep stage), the heat should be lowered to a medium setting.
(c) While the subject continues to sleep (i.e., is in a mid-sleep stage), the heat should be lowered to a low setting, or maintained at the medium setting.
(d) As the subject is awakening at a normal time (i.e., is in an awakening stage), and/or is awakening prematurely (i.e., is in a premature-awakening stage), the heat should be raised back to the high setting.
The control unit differentially identifies the relevant sleep stages, and controls the room-climate-regulation device in accordance with the subject's input. For example, upon ascertaining that the subject is in an awakening stage and/or a light sleep stage, rather than a mid-sleep stage and/or a deep sleep stage, the control unit may raise the temperature in the room. In some applications, the control unit also controls another device, such as an alarm clock, in response to the differentially identified sleep stages. For example, upon reaching the subject's desired awakening time, the control unit may wait until the subject is in an awakening stage, and then activate the alarm clock.
In some applications, the control unit drives the user interface to prompt the subject to enter the input, in response to a change in a relevant parameter. For example, in response to a change in season, an ambient temperature, an ambient humidity, and/or a going-to-sleep time (e.g., the subject is going to bed at an unusual time), the control unit may drive the user interface to prompt the subject to re-enter his room-climate preferences. (The control unit may identify the change of the relevant parameter in a variety of ways, such as, for example, by receiving input from a sensor, or by checking the Internet.) In some applications, sensor 22 senses a weight of a blanket of the subject, and the control unit drives the user interface to prompt the subject to enter the input, in response to a change in the sensed weight. For example, the subject may be prompted to enter the input upon the subject switching to a heavy winter blanket.
Aspects of the control of the room-climate-regulation device, as described above, are depicted in

In some applications, the control unit computes a measure of relaxation, i.e., a relaxation score, for the subject, one or more times during a sleeping session. For example, a high relaxation score may be computed if the subject shows little movement, and little variation in both respiration rate and respiration amplitude. The relaxation score may be used to compute the sleep score. Alternatively or additionally, in response to a low relaxation score, the control unit may immediately adjust the room climate.
In some applications, the control unit controls the room-climate-regulation device in response to the low sleep score, even without any input from the user. For example, if, in the summer, the subject woke up shivering in the middle of the night, the control unit may ascertain that the strength of the air conditioning was not lowered quickly enough. In response thereto, the control unit may adjust the subject's room-climate-control profile, such that, for example, the temperature in the room rises soon after the subject falls asleep. In some applications, in response to the low sleep score, the control unit generates an output (e.g., via user interface 180) that includes a suggested setting for the room-climate-regulation device. For example, with reference to
It is noted that in the context of the claims and description of the present application, the word “setting” has a broad definition, in that it encompasses at least (a) a particular mapping in a room-climate-control profile (e.g., a room-climate-control profile may specify a high temperature “setting” for the falling-asleep stage), and (b) the room-climate-control profile itself. Thus, depending on the particular context, the word “setting” may refer to (a), or (b), or both.
In some applications, in response to a premature awakening of the subject, the control unit is configured to change a setting of the room-climate-regulation device, to facilitate the subject falling asleep again. For example, the control unit may set the room-climate-regulation device to whichever setting helped the subject fall asleep at the beginning of the night.

Before each sleeping session, the control unit sets the device at device-setting step 194. After the sleeping session, the control unit ascertains the sleep score, at sleep-score-ascertaining step 198. At an is-sweep-finished-determination step 202, the control unit determines whether more settings should be tried. If the control unit determines that no more settings should be tried (since, for example, a local maximum of the sleep score was attained), the control unit ascertains, at an optimal-setting-determination step 204, which setting maximizes the sleep score, i.e., which setting yields at least a local maximum of the sleep score. At an output-generating step 206, the control unit generates an output indicative of this “optimal” setting. For example, the output may include a control signal to the room-climate-regulation device that drives the device to use the optimal room-climate-control profile on subsequent nights. Alternatively or additionally, the output may include a signal to the user interface to display the optimal room-climate-control profile to the subject, and the subject may then edit and/or approve this profile, as described hereinabove.

In general, if two room-sharing subjects have different room-climate preferences, and/or are in different stages of sleep, managing the room climate may be challenging. As described hereinbelow, applications of the present invention address this challenge.
As shown in
In some applications, the room-climate-regulation device can simultaneously maintain a first setting in a vicinity of the first subject, and a second setting, which is different from the first setting, in a vicinity of the second subject. For example, electric blanket 210 may be able to simultaneously maintain a first temperature in area A, and a second temperature in area B. The control unit communicates the first and second settings (e.g., the first and second temperatures) to the room-climate-regulation device, in response to the respective identified sleep stages, and/or in response to other detected physiological activity of the subjects. In some applications, the control unit also ascertains a sleep score for each of the subjects, and controls the room-climate-regulation device in response to the sleep scores, e.g., as described hereinabove.
In some cases, the room-climate-regulation device can maintain only a single setting. In such cases, the control unit may determine a “compromise” setting that is at least somewhat acceptable to each of the subjects. A compromise setting may be determined in response to an average sleep score of the subjects. For example, the control unit may determine a setting of the room-climate-regulation device that maximizes the average sleep score of the subjects (e.g., a setting that minimizes the average falling-asleep time). Alternatively, the compromise setting may be a setting of the room-climate-regulation device that facilitates respective sleep scores of the subjects being equal to one another. If both subjects are trying to fall asleep, the control unit may communicate the compromise setting, such as to give each subject a “fair chance” of falling asleep. Upon one of the subjects falling asleep, the control unit may communicate a second, different setting that is at least somewhat more sleep-conducive for the subject who is still awake, relative to the first setting.
Alternatively, in response to one of the sensor signals indicating that one of the subjects is trying to fall asleep, the control unit may first communicate a setting that is at least somewhat more sleep-conducive for that subject, relative to the other subject, to help that subject fall asleep. Subsequently, in response to the sensor signals indicating that (a) the subject has fallen asleep, and (b) the other subject is trying to fall asleep, the control unit may communicate a second setting to the room-climate-regulation device, the second setting being at least somewhat more sleep-conducive for the other subject, relative to the first setting, to help the other subject fall asleep. Once both subjects are asleep, the control unit may communicate a compromise setting to the room-climate-regulation device, as described hereinabove.
In some applications, the control unit makes gradual changes to the settings. For example, if Subject A prefers a temperature of 23 C, and Subject B prefers 25 C, the control unit may first communicate a setting of 23 C, to help Subject A fall asleep. Subsequent to Subject A falling asleep, the control unit may change the setting to 24 C. If Subject B does not fall asleep within a reasonable amount of time, the temperature may then be changed to 25 C. By not immediately changing the temperature to 25 C subsequent to Subject A falling asleep, the control unit may help prevent Subject A from waking up prematurely.
In some cases, e.g., cases in which the subjects' room-climate preferences for falling asleep are very different from one another, one of the subjects may wish to wait outside the room until the other subject is asleep. In such applications, the control unit may generate an output (e.g., a text message) to the waiting subject, the output indicating that the subject's partner has fallen asleep. Then, the room-climate setting may be adjusted, to help the still-awake subject fall asleep.

For example, for two subjects who share a room, room-climate-regulation device 170 may have three distinct settings, corresponding respectively to (a) a situation in which the first subject, but not the second subject, is present, (b) a situation in which the second subject, but not the first subject, is present, and (c) a situation in which both subjects are present. For example, the first and second settings may be, respectively, the first subject and second subject's “optimal” temperatures for falling asleep, the third setting being an intermediate (“compromise”) setting between the first and second settings. The control unit then sets the room-climate-regulation device to the appropriate setting, in response to determining which of the subjects is present. In some applications, the control unit establishes the three distinct settings, in response to analyzing the sensor signal. For example, the control unit may use machine-learning techniques to establish the respective “optimal” settings for scenarios (a)-(c) described above. Alternatively or additionally, the control unit may establish the settings via any of the techniques described hereinabove with reference to

Apparatus 20 comprises one or more physiological sensors 22, which are configured to monitor conditions of the subjects and to generate, in response thereto, a respective sensor signal for each one of the subjects. Control unit 28 analyzes the sensor signals, and, in response thereto, determines a prioritization of the condition of one of the subjects over the condition of another one of the subjects. In response to the prioritization, the control unit decides whether to control controllable mechanism 234. Subsequently, in response to (i) the prioritization, and (ii) deciding to control the controllable mechanism, the control unit controls the controllable mechanism by communicating a control signal to the controllable mechanism.
In general, the concept of “prioritizing a condition,” as used in the claims and description of the present application, should be understood to include at least the idea of “trading off” potentially conflicting needs and/or preferences of the plurality of subjects. For example, at times the condition of Subject A (which may be either one of subjects 236 and 238) is more pressing than that of Subject B (which is the other one of subjects 236 and 238), such that Subject B may have to suffer for the sake of Subject A. Thus, for example, the control unit may control the controllable mechanism for the benefit of Subject A, even to the detriment of Subject B.
For example, as shown in
In general, apparatus 20 as shown in
In some applications, the “condition” is comfort, i.e., sensors 22 monitor comfort of the subjects, and the control unit prioritizes the comfort of one subject over the comfort of another subject. For example, in response to the sensor signals indicating that one of the subjects is shivering, the control unit may prioritize the comfort of the shivering subject, and subsequently raise the temperature in the room, even if another subject is more comfortable with the current temperature than with the new, higher temperature. In such applications, common area 232 may be a common sleeping area, or may be a different type of common area, e.g., a living room. (For example, sensors 22 may be worn on the bodies of the subjects and/or placed inside sofas or recliners in the living room.)
In some applications, controllable mechanism 234 is an adjustable resting surface 240 (e.g., a shared adjustable resting surface), the control unit controlling adjustable resting surface 240 in response to the prioritization of the condition (e.g., sleep and/or comfort) of one of the subjects. (
In some applications, controllable mechanism 234 is an illumination device 244 (e.g., a lamp, as shown), the control unit controlling illumination device 244 in response to the prioritization. For example, the control unit may darken or lighten the room to a particular illumination level in order to facilitate the sleep and/or comfort of subject 238, even if subject 236 prefers a different illumination level, and even if the particular illumination level is detrimental to the sleep and/or comfort of subject 236. In this context, apparatus 20 may be used in combination with techniques described in WO 2015/008285 to Shinar (e.g., techniques described with reference to
In some applications, controllable mechanism 234 is a sound-playing device (e.g., speaker 70, described hereinabove), the control unit being configured to control the sound-playing device in response to the prioritization. For example, the control unit may adjust speaker 70 to a particular volume in order to facilitate the sleep and/or comfort of subject 238, even if subject 236 prefers a different volume, and even if the particular volume is detrimental to the sleep and/or comfort of subject 236.
In some applications, the control unit is configured to determine the prioritization in response to a health condition of at least one of the subjects. For example, in response to analyzing the sensor signals, the control unit may determine that subject 236 is experiencing an asthma attack, and/or has experienced asthma attacks in the past. In response, the control unit may prioritize the sleep and/or comfort of subject 236, and consequently, drive room-climate-regulation device 170 to blow cold air into the room, even if the cold air is disruptive to the sleep and/or comfort of subject 238. In some applications, apparatus 20 comprises at least one body-temperature sensor (e.g., integrated with a wristwatch 246) configured to (i) detect a body temperature of at least one of the subjects, and (ii) generate a body-temperature signal in response thereto, the control unit being configured to determine the health condition of the subject(s) in response to the body-temperature signal(s).
In some applications, user interface device 35 (described hereinabove with reference to
In some cases, controlling the controllable mechanism in a particular manner is (i) facilitative to sleep of a first subject, but (ii) at least potentially detrimental to sleep of a second subject; in such cases, the control unit decides to control the controllable mechanism in the particular manner only if the prioritization indicates that sleep of the first subject is to be prioritized over sleep of the second subject. (In the context of the claims and description of the present application, “at least potentially detrimental” means there is at least a small (but non-negligible) likelihood that the sleep of the second subject will be disturbed.) For example, as noted above, a change in the room temperature may facilitate the sleep of one subject, but potentially disrupt the sleep of another subject. Other examples include cases in which one of the subjects is snoring. In such cases, as further described immediately hereinbelow, the control unit may activate a snoring-inhibition mechanism 248 that is disruptive to sleep of the snoring subject, in order to inhibit the snoring, and thus help another subject sleep.
For some applications, in response to analyzing the sensor signals, the control unit determines that (i) one of the subjects is snoring, and (ii) another one of the subjects may be disturbed by the snoring. (The snoring may be identified, for example, using techniques described in US 2007/0118054 to Pinhas, now abandoned, which is incorporated herein by reference.) In response thereto, the control unit decides to activate snoring-inhibition mechanism 248, unless the prioritization indicates that sleep of the snoring subject is to be prioritized over sleep of the other one of the subjects. An example of snoring-inhibition mechanism 248 is a vibrating mechanism 250, which, by vibrating, disrupts the sleep of the snoring subject and/or “nudges” the snoring subject to change position, thus inhibiting future snoring. For example, a vibrating mechanism 250 may be disposed underneath the mattress, and/or wristwatch 246 may be configured to vibrate. Another example of snoring-inhibition mechanism 248 is adjustable resting surface 240 (e.g., an adjustable mattress or pillow), which, by being adjusted, disrupts the sleep of the snoring subject and/or moves the subject to a different position in which snoring is less likely to occur. (The snoring-inhibition techniques described here may be practiced in combination with posture detection, as described hereinbelow with reference to
Typically, the control unit identifies respective sleep stages of the subjects by analyzing the sensor signals, and determines the prioritization in response to identifying the respective sleep stages. For example, the control unit may identify that each of the respective sleep stages is a slow-wave (i.e., deep) sleep stage, a rapid-eye-movement (REM) sleep stage, a light sleep stage, or an awake sleep stage. (In the context of the claims and description of the present application, a subject who is awake is considered to be in an “awake sleep stage.”) The control unit further assigns a rank to each sleep stage, where slow-wave sleep and REM sleep have the two lowest rankings, light sleep has the next-highest ranking, and awake has the highest ranking. (Slow-wave sleep may be ranked higher or lower than REM sleep.) The likelihood of the control unit prioritizing the sleep of a first subject over the sleep of a second subject generally increases or decreases with the rank of the first subject's sleep stage. For example, Table 1 below shows an illustrative example of a manner in which the control unit may determine whether to activate snoring-inhibition mechanism 248, in response to the respective sleep stages of the subjects. (Similar tables may be constructed to show how the control unit might prioritize the sleep of the subjects in other contexts, e.g., for adjusting the lighting or temperature in the room, mutatis mutandis.)
As illustrated in Table 1, as the rank of the sleep stage of the snoring subject decreases, the sleep of the snoring subject is more likely to be prioritized over the sleep of the other subject. One reason for this is that the quality, e.g., the benefits, of slow-wave and REM sleep is greater than that of light sleep. Thus, for example, the snoring subject suffers less if he is awakened from light sleep than if he is awakened from REM or deep sleep. On the other hand, as the rank of the sleep stage of the other subject decreases, the sleep of the other subject is less likely to be prioritized over the sleep of the snoring subject. One reason for this is that the snoring is less likely to disturb the other subject if the other subject is in a relatively deeper stage of sleep, than if the other subject is in a relatively lighter stage of sleep.
In some applications, the control unit analyzes the sensor signals over a plurality of sleeping sessions, and identifies, for each of the subjects, a sleep-sensitivity of the subject to at least one phenomenon that is generally detrimental to sleep (e.g., a noise or lighting disturbance). For example, the control unit may analyze the duration and/or quality of sleep of the subjects in response to various noise disturbances over the plurality of sleeping sessions. If, for example, subject 238 is seen to be woken more than subject 236, and/or is seen to fall asleep after the disturbances less quickly than subject 236, and/or is seen to have a greater reduction in sleep quality than subject 236 as a result of the noise, the control unit may determine that subject 238 has a greater sleep-sensitivity than subject 236. The control unit then determines the prioritization in response to the identified sleep-sensitivities. Typically, the control unit is more likely to prioritize the sleep of a first subject over the sleep of a second subject if the sleep-sensitivity of the first subject is higher than the sleep-sensitivity of the second subject. For example, Table 2 below is an illustrative modification of Table 1 that shows, by way of example, how the control unit might “tweak” the prioritization in response to the non-snoring (“other”) subject having a greater sleep-sensitivity than the snoring subject. (The asterisked entries are those that differ from Table 1.)
In some applications, the control unit is configured to take into account the duration and/or quality of sleep of the subjects during a preceding interval, e.g., during the night thus far, and/or during the previous night or last several nights. In some applications, the duration and/or quality of sleep may be the basis of a sleep score, which the control unit calculates at a particular time in response to analyzing the sensor signals. The control unit then determines the prioritization in response to the respective sleep scores. For example, if the snoring subject has slept well prior to the particular time, while the other subject has not slept well, the sleep score of the snoring subject will be adjusted, for example, such that the sleep score of the snoring subject becomes higher than that of the other subject. The control unit may then be more likely to prioritize sleep of the other subject over sleep of the snoring subject, relative to if the sleep score of the snoring subject were not higher than the sleep score of the other subject. (For example, if the snoring subject has a higher sleep score than the other subject, the control unit may use Table 2, rather than Table 1, in deciding whether to activate the snoring-inhibition mechanism.)
In some cases, as noted above, controlling the controllable mechanism in a particular manner is (i) facilitative to sleep of a first subject, and (ii) at least potentially detrimental to sleep of a second subject. For example, if subject 238 is having difficulty falling asleep, turning on relaxing music may facilitate the sleep of subject 238, but may possibly wake subject 236. Alternatively, if subject 236 is snoring, activating the snoring-inhibition mechanism may facilitate the sleep of subject 238, but will likely disrupt the sleep of subject 236. In such cases, in some applications, the control unit is configured to control the controllable mechanism in the particular manner only if the second one of the subjects is not sleeping deeply. Thus, in the examples provided immediately above, subject 236 is “spared” if he is sleeping deeply.
Also in such cases, the control unit may compare the sleep score of the first subject to a threshold, and control the controllable mechanism in the particular manner in response to the sleep score being lower than the threshold. For example, if, at a time close to morning, subject 238 has not yet slept for six hours, the control unit may be more likely to inhibit the snoring of subject 236, relative to if subject 238 were to have already slept for six hours. The decision is typically also based on the respective sleep stages of the subjects; for example, in response to the sleep score of subject 238 being lower than the threshold, the control unit may decide to inhibit the snoring of subject 236, but only if subject 238 and/or subject 236 is not sleeping deeply. Similarly, the sleep score of the second subject may be compared to a threshold. For example, if subject 236 has already slept for eight hours, the snoring of subject 236 may be inhibited whenever the snoring is potentially disturbing to subject 238.
Table 3 below is another illustrative and non-limiting “decision table,” corresponding to a case in which the sleep score of the other (non-snoring) subject is less than a threshold, as described hereinabove. (The asterisked entries are those that differ from Table 1.)

For the applications shown in
Alternatively or additionally, the control unit drives electromechanical arm 262 to deliver comfort-inducing object 264 to the baby, in response to ascertaining that the baby's mouth is performing a sucking motion. Typically, the frequency of a baby's sucking motion is different from that of the baby's heart rate and respiratory rate. Hence, if the control unit detects three dominant frequencies in the sensor signal, and particularly if one of those frequencies is a typical sucking frequency (such as a frequency in the range of 1-2 Hz), the control unit may ascertain that the baby's mouth is performing a sucking motion.
Alternatively or additionally to controlling electromechanical arm 262, the control unit may generate an alert, in response to the baby being in a light sleep, and/or in response to the sucking motion. For example, the control unit may alert a parent 266 of the baby that the baby is in need of food or comfort. Such an alert may improve the quality of care that is provided to the baby, and/or may help reduce the likelihood of the baby waking other members of the household.

In many cases, a patient may be in need of a care-provision task that is potentially disturbing to the patient's sleep or to sleep of the patient's roommate; for example, a nurse may need to come into the room one or more times during the night to check the patient's blood pressure, temperature, etc. As described immediately hereinbelow, apparatus 270 generally reduces the disturbance to the sleep of the patients, by prioritizing care-provision tasks that are likely to be less disturbing.
Apparatus 270 comprises the plurality of sensors shown in
In some applications, apparatus 270 further comprises a location sensing system that comprises a plurality of location sensors 286, as described in US 2013/0267791 to Halperin, which is incorporated herein by reference. The location sensing system is configured to identify respective locations of a plurality of care-providers (e.g., clinicians) and/or respective locations of the patients, and to generate a location-sensing-system signal in response thereto. Control unit 278 determines the prioritization further in response to the location-sensing-system signal. For example, if a clinician who is responsible for both patient 1 and patient 2 is closer to patient 1 than to patient 2, the control unit may output a message to the clinician to prioritize patient 1 over patient 2, if patient 1 and patient 2 are in a similar sleep state, e.g., both are awake. In some applications, patient 1 may be prioritized over patient 2 even if patient 2 is sleeping less heavily than patient 1, and/or despite another indicator that would otherwise have favored prioritizing patient 2. Control unit 278 typically determines the prioritization further in response to time-sensitive factors derived from the signals (e.g., heartbeat and/or respiratory signals) from sensors 22. For example, if, by analyzing the signals from the respective patients, the control unit determines that patient 2 is in more urgent need of care than patient 1, patient 2 may be prioritized over patient 1, despite sleep-stage or location factors favoring the prioritization of patient 1.
It is noted that apparatus 270 need not necessarily include a central monitoring system. For example, multiple control units 28 belonging to respective patient monitoring systems may be in communication with each other, and the functionality described hereinabove may be executed by one or several of these control units.

In some situations, it is desired to ascertain that a particular subject is getting enough sleep, and/or is sleeping at a particular time. For example, a health insurance company may wish to verify that an insured individual is sleeping healthfully, or a trucking company may wish to verify that a truck driver is getting enough sleep while on the road. In such situations, merely verifying that someone is resting on resting surface 304 is insufficient; rather, the resting person must be identified as the subject with a reasonable degree of confidence. As described hereinbelow, apparatus 20 facilitates this identification by ascertaining that a handheld telecommunications device 306 (e.g., smartphone 36) of the subject is not moving and/or is not being used, such that the resting person is likely to be the subject.
Apparatus 20 comprises sensor 22 and processor 28, which, as described hereinabove, may be a dedicated processor, or may be embodied within a user interface device, e.g., handheld telecommunications device 306 (e.g., smartphone 36) of the subject. (In the latter case, device 306 may communicate directly with sensor 22, e.g., wirelessly.) Sensor 22 monitors resting surface 304, and generates a sensor signal in response thereto. By analyzing the sensor signal, the processor may ascertain that a person is resting on the resting surface. However, the processor may not necessarily ascertain, from the sensor signal alone, whether the resting person is the subject; therefore, the processor also analyzes a signal generated by device 306, which provides a further indication as to whether the subject is resting. Examples of signals generated by device 306 that may be analyzed alone or in combination with each another are the following:
(i) A device-movement signal: The telecommunications device may include a device-movement sensor (e.g., an accelerometer or a GPS sensor) configured to detect movement of the telecommunications device and to generate a device-movement signal in response thereto.
(ii) A usage signal: The telecommunications device may generate a signal indicative of whether the telecommunications device is being used (e.g., whether there is a call in progress, outgoing communication, or any application-use).
Processor 28 identifies a level of correspondence between the sensor signal and the signal generated by the telecommunications device. For example, the level of correspondence may be said to be relatively high if (i) the sensor signal indicates that a person is resting on the resting surface, and the signal generated by the telecommunications device indicates that the device is not being used and/or is not moving, or (ii) the sensor signal indicates that no one is resting on the resting surface, and the signal generated by the telecommunications device indicates that the device is being used and/or is moving. Conversely, the level of correspondence may be said to be relatively low if (i) the sensor signal indicates that a person is resting on the resting surface, but the signal generated by the telecommunications device indicates that the device is being used and/or is moving, or (ii) the sensor signal indicates that no one is resting on the resting surface, but the signal generated by the telecommunications device indicates that the device is not being used and/or is not moving. In response to the level of correspondence, the processor generates an output 308 (e.g., a message displayed on a remote device) that is indicative of whether the subject is likely to be resting on the resting surface.
In general, the processor ascertains that the subject is likely to be resting on the resting surface only if the processor identifies a relatively high level of “positive” correspondence, i.e., the processor ascertains (a) from the sensor signal that a person is resting on the resting surface, and (b) from the signal generated by device 306 that the telecommunications device is not being used and/or is not moving. If, on the other hand, there is a relatively low level of correspondence, or if there is a relatively high level of “negative” correspondence (i.e., both signals suggest that the subject is not resting on the resting surface), the processor will ascertain that the subject is not likely to be resting on the resting surface. Output 308 is generated in response to the ascertaining.
Alternatively or additionally to the identification of a level of correspondence between the sensor signal and a signal generated by device 306, processor 28 may, in response to a signal generated by the telecommunications device, determine if the telecommunications device is within a given distance of the resting surface. If the telecommunications device is within the given distance, the processor ascertains that the subject is likely to be resting on the resting surface, and generates output 308 in response thereto. Conversely, if the telecommunications device is not within the given distance of the resting surface, the processor ascertains that the subject is not likely to be resting on the resting surface, and generates output 308 in response thereto. For example, the processor may check that a short-range signal emitted from the vicinity of the resting surface, e.g., by a wireless-communication component of sensor 22, is received by the telecommunications device. (In the context of the present claims and description, the phrase “given distance” does not necessarily connote a precise numerical distance, but rather, can connote a general range of distances, e.g., the processor may determine if the telecommunications device is within Bluetooth™ range of the resting surface.) Alternatively or additionally, the processor utilizes a signal generated by the telecommunications device that is indicative of coordinates of a location of the telecommunications device, e.g., a GPS location signal. At some prior point in time, the processor receives an input indicative of coordinates of a location of the resting surface, e.g., by prompting the subject to press an input button on the telecommunications device while on the resting surface. The processor then ascertains that the telecommunications device is within the given distance of the resting surface by comparing the location of the telecommunications device with the location of the resting surface.
In some applications, by periodically analyzing a signal generated by the telecommunications device, the processor ascertains that the telecommunications device is periodically used by the subject when the subject is not on the resting surface. For example, the processor may ascertain that the telecommunications device moves periodically, and/or is used periodically, and/or is periodically not in the vicinity of the resting surface, i.e., the telecommunications device is periodically “active”. Further to this ascertaining, a “non-active” state of the telecommunications device is more indicative that the subject is likely to be resting on the resting surface, relative to if the telecommunications device were not known to be periodically “active”.

Typically, subject 24 is more likely to snore, cough, or have an apnea episode when the subject is in a supine position. Apparatus 20 reduces the frequency of snoring, coughing, and/or apnea of subject 24 by encouraging (e.g., by “nudging”) the subject to move from a supine position to a different position.
Control unit 28, which receives the signal from sensor 22 that monitors subject 24, identifies the subject's posture (e.g., sleeping position) by analyzing the sensor signal from sensor 22. (In identifying the subject's posture, the control unit may make use of techniques described in U.S. Pat. No. 8,821,418 to Meger, which is incorporated herein by reference.) In response to the identified posture, e.g., in response to the identified posture being a supine position, the control unit drives vibrating mechanism 318 to vibrate, and/or adjusts a parameter (e.g., an angle) of resting surface 240 by communicating a signal to the resting surface. (
In some applications, adjustable resting surface 240 comprises an inflatable pillow, the control unit being configured to adjust a level of inflation of the inflatable pillow. For example, to inhibit coughing and/or snoring, the control unit may drive an inflating mechanism to inflate the inflatable pillow, by communicating a signal to the inflating mechanism.
In some applications, the control unit, which receives the signal from sensor 22 that monitors subject 24, is further configured, in response to analyzing the sensor signal, to identify a sleep stage of the subject. The control unit then drives the vibrating mechanism to vibrate, and/or adjusts the parameter of the resting surface, further in response to the identified sleep stage. For example, the control unit may drive the vibrating mechanism to vibrate, and/or adjust the parameter of the resting surface, in response to the identified sleep stage being within 5 minutes of an onset or an end of an REM sleep stage, since at these points in time, the “nudging” or moving is less likely to disturb the subject's sleep.
In some applications, subject 24 shares a room with a partner 320, and a second sensor 22 monitors partner 320 and generates a second sensor signal in response thereto. As shown in
A control unit 28 analyzes the second sensor signal and, in response thereto, identifies a sleep stage of the partner. (As shown, there may be separate control units configured to receive and analyze the subject's and the partner's sensed signals, respectively. For such applications the control units are typically in communication with one another.) The control unit that controls the vibrating mechanism and/or the resting surface drives the vibrating mechanism to vibrate, and/or adjusts the parameter of the resting surface, further in response to the identified sleep stage of the partner. For example, the control unit may nudge or move the subject in response to the partner being in a light sleep stage, since at this stage, snoring of the subject is more likely to disturb the partner.
In some applications, control unit 28, which receives the signal from sensor 22 that monitors subject 24, is further configured to identify a snoring, coughing, or apnea episode of the subject, e.g., by using techniques described in US 2007/0118054 to Pinhas (now abandoned), which is incorporated herein by reference. In response to the identified episode (alternatively or additionally to the other factors described above, such as the sleep state of the subject), the control unit nudges or moves the subject.

Components of apparatus 340 are generally similar to those of subject-monitoring apparatus 20 described hereinabove with reference to
For example, using apparatus 340:
(a) An alert may be generated if, by analyzing the motion signal, the control unit identifies an elevated stress level of a subject, e.g., by identifying an elevated heart rate, and/or a decreased stroke volume, e.g., as described in WO 2015/008285 to Shinar, which is incorporated herein by reference. For example, in response to the pilot experiencing an elevated stress level, the control unit may generate an alert to another member of the flight crew, and/or individuals on the ground. The control unit may also analyze the signal of the co-pilot, and generate an alert in response to both the pilot and co-pilot experiencing an elevated stress level, since the presence of an elevated stress level in both individuals at the same time is likely to be indicative of an emergency situation. Similarly, an alert may be generated if two or more passengers experience an elevated stress level at the same time.
(b) An alert may be generated if, by analyzing the motion signal, the control unit identifies that it is likely that the subject is experiencing, or will soon experience, a clinical event, such as a heart attack. For example, if the pilot or one of the passengers is experiencing a heart attack, members of the flight crew, and/or a physician who is travelling on the airplane, may be alerted to the situation.
(c) An alert may be generated if, by analyzing the motion signal, the control unit identifies that it is at least somewhat likely that the subject is a carrier of a disease, such as severe acute respiratory syndrome (SARS). For example, if the control unit identifies a change in the baseline heart rate of the subject without any correlation to motion of the subject, the control unit may ascertain that the subject has likely experienced a rapid change in body temperature, which may indicate that the subject is sick. (The baseline heart rate is typically an average heart rate over a period of time, e.g., 1-2 hours.) In response, the control unit may alert the flight crew to isolate the subject.
(d) An alert may be generated if, by analyzing the motion signal, the control unit identifies that the subject (in particular, the pilot or co-pilot) is drowsy or sleeping.
(e) A sleep study may be performed. For example, the control unit may analyze the motion signals from various passengers, and identify which passengers were sleeping at which times. In response, the control unit may generate an output to help the airline improve the sleeping conditions on their aircraft (e.g., by reducing lighting, or increasing leg room).
Apparatus 340 may also be used to control the lighting, temperature, or other cabin-environment parameters, in order to facilitate a more pleasant travelling experience. For example, upon detecting that a significant number of passengers are sleeping or are trying to fall asleep, the lights in the cabin may be dimmed, and/or the movie that is playing may be stopped. Alternatively or additionally, meals may be served to the passengers only if a given number of passengers are awake. To help prevent deep vein thrombosis (DVT), passengers may be prompted to stand up and take a walk, if the control unit detects that they have been sitting in place for too long.

By analyzing the motion signals, control unit 28 identifies an elevated stress level of one or more subjects. An elevated stress level, which is commonly experienced while performing casino-related activities, may be indicative of an upcoming clinical event, particularly for subjects who are elderly and/or infirm. The control unit generates an alert in response to the elevated stress level, such that, for example, the subject can be told to take a break from his activities. In some cases, such as in multi-player games, simultaneous elevated stress levels of two or more subjects may indicate that the subjects are colluding. The control unit may therefore generate the alert in response to each of two or more subjects having an elevated stress level at the same time.

In some applications, as shown in
A first sensor 22a monitors resting surface 304 (e.g., the surface of mattress 26), and generates a signal in response thereto. Control unit 28 analyzes the signal. If, in response to the analyzing, the control unit determines that the resting surface is likely not being occupied by subject 236, the control unit inhibits the alarm clock from generating an alarm, and/or stops an alarm that is in progress. (Alternatively, the alarm clock does not generate an alarm unless it is driven to do so by the control unit, in response to the control unit determining that the resting surface is likely being occupied by subject 236.) This reduces the likelihood of an alarm waking other members of the household (e.g., a second subject 238, such as the subject's partner), in cases where first subject 236 arose from resting surface 304 without taking measures to ensure that the alarm would not subsequently begin or continue to sound. Typically, the control unit is configured to determine that the resting surface is likely not being occupied by first subject 236, even if the resting surface is occupied by someone. For example, even if the signal from a second sensor 22b indicates bed-occupation, the control unit may determine that the resting surface is likely not being occupied by first subject 236, if the signal from sensor 22a (on the right side of the bed) does not indicate bed-occupation.
In some cases, first subject 236 might arise from bed (thus causing the control unit to inhibit the generating of an alarm), but return to bed thereafter. Hence, the control unit is typically configured to stop inhibiting the alarm clock from generating an alarm, in response to determining that the resting surface is likely being occupied by first subject 236. (Alternatively, the control unit may drive the alarm clock to generate an alarm, in response to determining that the resting surface is likely being occupied by first subject 236.) In some cases, first subject 236 might not arise from bed, despite a first alarm having been generated by the alarm clock. Hence, the control unit is typically configured to drive the alarm clock to generate a second alarm, in response to determining that the resting surface is likely being occupied by the subject.
In some applications, when determining whether to inhibit the alarm clock from generating an alarm (or drive the alarm clock to generate an alarm), the control unit 28 also takes into account the sleep stage of second subject 238, who is typically a subject for whom the alarm is not intended. For example,
For example, at an earliest desired awakening time of 6:00, the control unit may check the sleep stage of second subject 238. If second subject 238 is sleeping lightly, the control unit may withhold driving the alarm clock to generate an alarm until (i) second subject 238 wakes up or begins to sleep more deeply, or (ii) the latest desired awakening time (e.g., 6:30) is reached. Alternatively, the alarm may be set for 6:00, and the control unit may inhibit the alarm clock from generating the alarm until condition (i) or (ii) is satisfied.
In some applications, the control unit analyzes the sensor signal over a plurality of sleeping sessions, and identifies a sleep-sensitivity of second subject 238 to at least one phenomenon that is generally detrimental to sleep, e.g., as described hereinabove with reference to
Alternatively or additionally, the control unit may calculate a sleep score for the second subject, the sleep score being based on the duration and/or quality of the second subject's sleep during a preceding interval, as described hereinabove with reference to FIG. 18. In response to the sleep score, the control unit decides whether to drive the alarm clock to generate an alarm. For example, if the sleep score of second subject 238 is low (e.g., second subject 238 had a less-than-average amount of slow-wave and REM sleep during the night), the control unit may withhold from driving the alarm clock to generate an alarm until second subject 238 is awake or the latest desired awakening time is reached.
Alternatively or additionally, the control unit may determine whether to drive the alarm clock to generate an alarm in response to a health condition of the second subject. For example, if second subject 238 is recovering from an illness, the control unit may withhold from driving the alarm clock to generate an alarm until second subject 238 is awake or the latest desired awakening time is reached.

Sensor 22 measures a clinical parameter (e.g., a heart rate or breathing rate) of the patient, and generates a signal in response thereto. Control unit 28 receives the signal from the sensor and compares the clinical parameter to a threshold 390. In response to the comparison, the control unit may generate an alert 392 to a clinician, via user interface device 35 (which is typically as described with reference to
For example, if threshold 390 for the patient's heart rate is 90 beats per minute, and the patient's heart beat exceeds the threshold, then the control unit may generate alert 392. The responding clinician then examines the patient, and determines whether the alert was justified. If the clinician indicates, via user interface device 35, that the alert was not justified (i.e., it was a “false alarm”), the control unit may adjust the threshold, for example, to 95 beats per minute. Alternatively, if the clinician indicates that the alarm was justified (i.e., it was a “true alarm”), the control unit may “be conservative” and adjust the threshold to 85 beats per minute. In this manner, the feedback loop depicted in
In general, the adjustment of the threshold may be in response to more than one input. For example, the control unit may adjust the threshold only after several false alarms. The control unit may also adjust the threshold in response to one or more inputs that were received in response to alerts that were generated for a different patient. For example, if Patient A is afflicted by a particular virus, and there is a chance that Patient B might have caught the same virus, the threshold for Patient B may be adjusted in response to a “true alarm” input for Patient A.
In general, computer processor 28 may be embodied as a single computer processor 28, or a cooperatively networked or clustered set of computer processors. Computer processor 28 is typically a programmed digital computing device comprising a central processing unit (CPU), random access memory (RAM), non-volatile secondary storage, such as a hard drive or CD ROM drive, network interfaces, and/or peripheral devices. Program code, including software programs, and data are loaded into the RAM for execution and processing by the CPU and results are generated for display, output, transmittal, or storage, as is known in the art. Typically, computer processor 28 is connected to one or more sensors via one or more wired or wireless connections. Computer processor 28 is typically configured to receive signals (e.g., motion signals) from the one or more sensors, and to process these signals as described herein. In the context of the claims and specification of the present application, the term “motion signal” is used to denote any signal that is generated by a sensor, upon the sensor sensing motion. Such motion may include, for example, respiratory motion, cardiac motion, or other body motion, e.g., large body-movement. Similarly, the term “motion sensor” is used to denote any sensor that senses motion, including the types of motion delineated above.
Applications of the invention described herein can take the form of a computer program product accessible from a computer-usable or computer-readable medium (e.g., a non-transitory computer-readable medium) providing program code for use by or in connection with a computer or any instruction execution system, such as computer processor 28.

Current examples of optical disks include compact disk-read only memory (CD-ROM), compact disk-read/write (CD-R/W) and DVD.
A data processing system suitable for storing and/or executing program code will include at least one processor (e.g., computer processor 28) coupled directly or indirectly to memory elements (e.g., memory 29) through a system bus.
