This invention relates broadly and generally to an article comprising a temperature-conditioned surface, thermoelectric control unit, and method for temperature-conditioning the surface of an article.
It is generally known in the prior art to provide a temperature-conditioned surface. It is desirable to control the temperature of a bed or other piece of furniture that supports a person, such as when sleeping. Such control has therapeutic value in treating symptoms of menopause or conditions of hypothermia or hyperthermia, particularly when those conditions manifest themselves over a long period of time. Therapeutic value may also be seen for individuals who have circulatory disorders, sleep disorders, and other conditions that may be improved by increasing the comfort felt during sleep. Such control can be desirable even outside the therapeutic value of cooling or heating a surface (e.g., mattress), simply to match the personal comfort preferences of healthy individuals, to promote higher quality sleep, or to provide localized control when a more general control (e.g., heating or air conditioning of a sleeping space) is unavailable or when adjustments to the general control would cause others discomfort or would be inefficient from an energy consumption perspective.
Various methods of temperature control are known, including such classic systems as electric blankets or heating pads, as well as more recent developments that involve the circulation of a heated or cooled fluid through a mattress, such as directing air through the chambers of an air mattress or directing air or a fluid through a tube that is embedded within a mattress or a mattress pad. The more advanced of these systems utilize a heat source or sink (i.e., cooling source) to heat or cool a reservoir of fluid to a selected target temperature and pump the heated or cooled fluid through the available conduit, relying on principles of heat exchange to control the surface temperature.

In another embodiment, the touch control and display board includes a program selection menu.
The control unit 10 preferably has at least one processor. By way of example, and not limitation, the processor may be a general-purpose microprocessor (e.g., a central processing unit (CPU)), a graphics processing unit (GPU), a microcontroller, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a Programmable Logic Device (PLD), a controller, a state machine, gated or transistor logic, discrete hardware components, or any other suitable entity or combinations thereof that can perform calculations, process instructions for execution, and/or other manipulations of information. In one embodiment, one or more of the at least one processor is operable to run predefined programs stored in at least one memory of the control unit 10.
The control unit 10 preferably includes at least one antenna, which allows the control unit 10 to receive and process input data (e.g., temperature settings, start and stop commands) from at least one remote device (e.g., smartphone, tablet, laptop computer, desktop computer, remote control). In a preferred embodiment, the at least one remote device is in wireless network communication with the control unit. The wireless communication is, by way of example and not limitation, radiofrequency, Bluetooth, ZigBee, Wi-Fi, wireless local area networking, near field communication (NFC), or other similar commercially utilized standards. Alternatively, the at least one remote device is in wired communication with the control unit through USB or equivalent.
In a preferred embodiment, the at least one remote device is operable to set target temperatures for the mattress pad. The at least one remote device preferably has a user interface (e.g., a mobile application for a smartphone or tablet, buttons on a remote control) that allows a user to select target temperatures for the mattress pad or independent zones within the mattress pad. In one embodiment, the mattress pad includes temperature probes in each zone that provide temperature data for that zone to the at least one processor, which compares a target temperature set using the at least one device to an actual measured temperature to determine whether to heat or cool the fluid and determine where to distribute the heated or cooled fluid in order to make the actual temperature match the target temperature.
Those skilled in the art will recognize that programmatic control of the target temperatures over time, such as over the course of a night's sleep, is possible using the at least one remote device. Because the target temperatures can be set at any time, those target temperatures can be manipulated through the sleeping period in order to match user preferences or a program to correlate with user sleep cycles to produce a deeper, more restful sleep.
In one embodiment, a larger number of temperature probes are in the independent temperature zones corresponding to the core body region, and a smaller number of temperature probes are in the independent temperature zones not corresponding to the core body region. In one example, zone 501 contains three temperature probes, zone 502 contains five temperature probes, and zone 503 contains three temperature probes. This embodiment provides the advantage of more closely monitoring the temperature of the pad in the core body region, which is important because core body temperature impacts how well a user sleeps.
In another embodiment, an independent temperature zone contains three temperature probes. In one example, zone 501 contains a temperature probe in the center of the mattress pad 11, a temperature probe on the left side of the mattress pad 11, and a temperature probe on the right side of the mattress pad 11. Advantageously, this embodiment provides information about the left, center, and right of the mattress pad. In yet another embodiment, an independent temperature zone contains at least three temperature probes.
The mattress pad includes padding 509 between the conduit circuits and the resting surface, in order to improve the comfort of a user and to prevent the concentrated heat or cold of the conduit circuits from being applied directly or semi-directly to the user's body. Instead, the conduit circuits heat or cool the padding 509, which provides more gentle temperature modulation for the user's body.
In this embodiment, despite the presence of two separate controls, a single control unit 10 is utilized to control the temperature of the fluid. In another embodiment, a first control unit is utilized to control the temperature of the fluid for the first user and a second control unit is utilized to control the temperature of the fluid for the second user. Alternatively, each user has at least two control units to control the temperature of the fluid.
Preferably, the mattress pad 11 is sized to fit standard mattress sizes. For example, twin (about 97 cm by about 191 cm (about 38 inches by about 75 inches)), twin XL (about 97 cm by about 203 cm (about 38 inches by about 80 inches)), full (about 137 cm by about 191 cm (about 54 inches by about 75 inches)), queen (about 152 cm by about 203 cm (about 60 inches by about 80 inches)), king (about 193 cm by about 203 cm (about 76 inches by about 80 inches), and California king (about 183 cm by about 213 cm (about 72 inches by about 84 inches)). In one embodiment, the mattress pad is about 76 cm by about 203 cm (about 30 inches by about 80 inches). This allows a single user of a full, queen, or king size bed to use the mattress pad without affecting a sleeping partner. In one embodiment, the mattress pad is sized to fit a crib mattress (about 71 cm by about 132 cm (about 28 inches by about 52 inches)). In a preferred embodiment, the single mattress pad (e.g., twin, twin XL, sized to fit a single user of a larger bed, crib) attaches to one control unit and the double mattress pad (e.g., full, queen, king, California king) attaches to two control units.
In an alternative embodiment, the mattress pad contains a conductive fiber to heat one section of the mattress pad and water circulation to cool another section of the mattress pad. In one example, this allows the temperature of the main body or body core region to be lower than the temperature for the feet. The feet play an active role in the regulation of body temperature. The feet have a large surface area and specialized blood vessels, which allow the feet to release heat from the body. If the feet become too cold, excess heat cannot be released from the body and an individual will not be able to sleep.
In one embodiment, the mattress pad is grounded, which provides the human body with electrically conductive contact with the surface of the earth. Grounding is based on the theory that the earth is a source of negatively charged free electrons, and, when in contact with the earth, the body can use these free electrons as antioxidants to neutralize free radicals within the body. Grounding the body during sleep can normalize cortisol levels, improve sleep, and decrease pain and stress levels. In a preferred embodiment, the mattress pad has a conductive material on at least one exterior surface of the mattress pad. In one embodiment, the mattress pad is attached to a wire that is electrically connected to an electrical outlet ground port. Alternatively, the mattress pad is attached to a wire that is connected to a ground rod.
The mattress pad includes at least two layers of a waterproof material that are laminated, affixed to each other, adhered to each other, attached to each other, secured to each other, or welded together to prevent separation or delamination of the layers. In a preferred embodiment, the waterproof material is a urethane or a mixture of urethane and ethylene-vinyl acetate (EVA). A first layer of the waterproof material is permanently affixed to a second layer of the waterproof material.

In one embodiment, the waterproof material is covered on the exterior surface with a moisture wicking material.
In one embodiment, the mattress pad includes a spacer layer positioned within the interior chamber between the interior surface of the first layer of the waterproof material and the interior surface of the second layer of the waterproof material. The spacer layer provides separation between the first layer of the waterproof material and the second layer of the waterproof material, ensuring that the fluid flows through the mattress pad when a body is on the mattress pad. The spacer layer advantageously provides structural support to maintain partial channels through the interior chamber or fluid passageways, which are important to ensure constant and consistent fluid flow through the interior chamber with heavy users on firm mattresses. In a preferred embodiment, the spacer layer is laminated, affixed, adhered, attached, secured, or welded to the first layer of the waterproof material and/or the second layer of the waterproof material. The spacer layer is preferably made of a foam mesh or a spacer fabric. In one embodiment, the spacer layer has antimicrobial properties.

The spacer layer is preferably made of a foam mesh or a spacer fabric. In one embodiment, the spacer layer has antimicrobial properties. In another embodiment, the spacer layer 610 is in a honeycomb shape.
A spacer layer 610 is positioned within the interior chamber 600 between an interior surface of the first layer of the waterproof material 602 and an interior facing of the second layer of the waterproof material 604. The spacer layer 610 is configured to provide structural support to maintain partial channels for fluid flow through the interior chamber. In one embodiment, the fluid flows through the spacer layer. In a preferred embodiment, the spacer layer is laminated, affixed, adhered, attached, secured, or welded to the first layer of the waterproof material and/or the second layer of the waterproof material. The spacer layer is preferably made of a foam mesh or a spacer fabric. In one embodiment, the spacer layer has antimicrobial properties.
A mattress pad hose elbow 108 is concentric around the flexible hose 106. The mattress pad hose elbow 108 secures the flexible hose 106 to the side of the mattress 102 and box springs or foundation 104, which provides structural support to the flexible hose 106. The mattress pad hose elbow 108 is sized to fit tightly around the flexible hose 106. In a preferred embodiment, the mattress pad hose elbow 108 is formed with silicone or rubber. Alternatively, the mattress pad hose elbow 108 is formed from plastic (e.g., ethylene-vinyl acetate (EVA) foam, polyethylene foam).

The mattress pad 11 preferably contains a plurality of holes or openings 100 in the surface of the mattress pad 11. The plurality of holes or openings 100 direct the movement of the fluid in the pad. In a preferred embodiment, the plurality of holes or openings 100 is in a pre-selected pattern to help manufacturing efficiency. Alternatively, the plurality of holes or openings 100 is in a random pattern. The plurality of holes or openings 100 is shown in a hexagon shape in
The spacing and number of the plurality of holes or openings 100 can be varied to adjust the thermal properties of the mattress pad. For example, in one embodiment, the density of the holes or openings is higher near the torso region than in the head and leg regions, for providing more exposure to the torso region of the user for managing body temperature in that region, and less exposure to the extremities of the user. In one embodiment, the spacing between each of the plurality of holes or openings is at least 5 mm (0.2 inches).
In a preferred embodiment, the mattress pad 11 contains at least one weld line 105 to help manage the flow of the fluid in the interior chamber. The at least one weld line 105 preferably directs the fluid flow through the pad from head to foot, and returns the fluid to the control unit via the return line. The at least one weld line 105 allows the fluid to flow across all areas of the mattress pad 11 to provide a substantially uniform temperature within the pad. In one embodiment, the at least one weld line is formed from the permanent attachment of the first layer of the waterproof material and the second layer of the waterproof layer along the periphery of the plurality of holes or openings.
In another embodiment, the flexible hose is positioned next to the mattress using hook and loop tape. In yet another embodiment, the flexible hose is positioned next to the mattress using elastic. In still another embodiment, the flexible hose is positioned next to the mattress using at least one snap. Alternatively, the flexible hose is positioned next to the mattress using at least one buckle.
In another embodiment, the top panel 110A and the bottom panel 110B act as a non-slip surface. In one embodiment, the top panel 110A and the bottom panel 110B are made of gripper or anti-slip fabric. In this embodiment, the non-slip pieces 112A and 112B are not needed because the top panel 110A and the bottom panel 110B act as the non-slip surface.
The single mattress pad is preferably reversible, such that the mattress pad is operable when either exposed surface is facing upward. Advantageously, this allows the flexible hose 106 to exit on either the left or the right side of the bed. This reversibility eliminates the need to manufacture single mattress pads with a “left” configuration or a “right” configuration for single users of a full, queen, or king size bed and/or single users where a bed is positioned such that a particular configuration is required (e.g., a bed positioned against a wall).
As previously described, the mattress pad 11 preferably contains a plurality of holes or openings 100 in the surface of the mattress pad 11. A first layer having a plurality of holes or openings is permanently affixed to a second layer having a plurality of holes or openings along a periphery of the mattress pad and a periphery of each of the plurality of holes or openings. At least one interior chamber is defined between an interior surface of the first layer and an interior surface of the second layer. The at least one interior chamber is constructed and configured to retain a fluid without leaking. The interior surface of the first layer and the interior surface of the second layer are made of at least one layer of a waterproof material.
In an alternative embodiment, the mattress pad 11 does not contain a plurality of holes or openings in the surface in the mattress pad 11. In one embodiment, the waterproof material is stretchable. In a preferred embodiment, the stretch rate of the waterproof material is equal to or greater than the stretch rate of surrounding materials (e.g., a mattress). Advantageously, this prevents the mattress pad 11 from gathering and bunching underneath a user.

Alternatively, the non-slip pieces 112 are formed from latex, silicon, or rubber. The non-slip pieces 112 are preferably moisture wicking and/or antimicrobial.
In alternative embodiments, the mattress pad includes interlock or knit fabric on exterior surfaces of the mattress pad. In other embodiments, the exterior surfaces of the mattress pad are covered with a woven fabric, a non-woven fabric, or a polymer film (e.g., urethane or thermoplastic polyurethane (TPU)). Additionally or alternatively, the mattress pad includes a spacer layer between an interior surface of the first layer of waterproof material 602 and an interior surface of the second layer of waterproof material 604.
The mattress pad 11 preferably contains at least one weld line or other separation to help manage the flow of fluid in the at least one interior chamber. The at least one weld line 105 directs the fluid flow through the pad from head to foot, and returns the fluid to the control unit via the return line. In
To secure the mattress pad 11 to the bed, the edge of the left side panel 110B and the edge of the bottom panel 110D are placed on top of the bottom non-slip piece 130C′. The top non-slip piece 130C is then placed on top the left side panel 110B, bottom panel 110D, and the bottom non-slip piece 130C′. The top non-slip piece 130C and bottom non-slip piece 130C′ are preferably formed from non-slip foam. Alternatively, the top non-slip piece 130C and bottom non-slip piece 130C′ are formed from silicone, rubber, or latex. In one embodiment, the left side panel 110B and the bottom panel 110D are formed from a material with stretch (e.g., interlock or knit). The top non-slip piece 130C and bottom non-slip piece 130C′ provide friction to keep the mattress pad in place.
As mentioned previously, the at least one remote device is operable to programmatically control the target temperatures over time, such as over the course of a night's sleep. Because the target temperatures can be set at any time, those target temperatures can be manipulated through the sleeping period in order to match user preferences or a program to correlate with user sleep cycles to produce a deeper, more restful sleep.

There are two main types of sleep: rapid eye movement (REM) sleep and non-rapid eye movement (non-REM) sleep. A sleep cycle typically lasts about 90 minutes, with REM sleep and non-REM sleep alternating within the sleep cycle. Non-REM sleep is divided into three stages: Stage 1 (“N1”, drowsy sleep), Stage 2 (“N2”, light sleep), and Stage 3 (“N3”, deep sleep).
The N1 stage is a transitional stage between wakefulness and sleep, and is characterized as a very light and easily disrupted sleep. During N1 sleep, breathing becomes more regular and the heart rate slows. N1 sleep typically lasts less than 10 minutes and accounts for approximately 2-5% of total sleep time. The N2 stage is a deeper stage of sleep. N2 sleep accounts for approximately 45-50% of total sleep time because sleepers pass through the N2 stage multiple times throughout the night. The N3 stage is deep sleep. During N3 sleep, brain temperature, breathing rate, heart rate, and blood pressure are each at their lowest levels. Deep sleep is associated with repairing and regrowing tissues, building bone and muscle, and strengthening the immune system.
REM sleep is a stage of sleep associated with random movement of the eyes. REM sleep accounts for approximately 20-25% of total sleep time. The first period of REM sleep begins approximately 90 minutes after sleep begins and lasts for approximately 10 minutes. Further, REM sleep is more prevalent in the last half of a sleeping period, such that the last REM stage may last up to about 60 minutes. Heart rate, breath rate, and blood pressure increase during REM sleep. Additionally, due to high brain activity, dreams are more prevalent in REM sleep. REM is associated with preserving memories and building neural connections.
Because deep sleep and REM sleep are the most regenerative parts of the sleep cycle, it is most beneficial to spend most of a sleeping period in deep sleep and/or REM sleep. The target temperature of the mattress pad can be manipulated over time through programmatic control using the at least one remote device. Because the target temperature can be manipulated using the at least one remote device, those target temperatures can be manipulated through the sleeping period to allow a user to spend more time in REM and/or deep sleep.

The predefined programs 740 are general sleep settings for various conditions and/or body types (e.g., weight loss, comfort, athletic recovery, hot flashes, bed sores, depression, multiple sclerosis, alternative sleep cycles). In one embodiment, a weight loss predefined program sets a surface temperature at a very cold setting (e.g., 15.56-18.89° C. (60-66° F.)) to increase a metabolic response, resulting in an increase in calories burned, which then leads to weight loss. Temperature settings are automatically adjusted to be as cold as tolerable by the user after the first sleep cycle starts to maximize the caloric burn while having the smallest impact on sleep quality. The core temperature of an overweight individual may fail to drop due to a low metabolism. In one example, the surface temperature is 20° C. (68° F.) at the start of a sleep period, 18.89° C. (66° F.) during N1-N2 sleep, 18.33° C. (65° F.) during N3 sleep, 19.44° C. (67° F.) during REM sleep, and 20° C. (68° F.) to wake the user.
In yet another embodiment, temperature modulation cycles are used to reduce insomnia. Insomnia may be caused by the core body temperature failing to drop or a delay of the drop in core body temperature. In one example, the surface temperature is 20° C. (68° F.) at the start of a sleep period, 17.78° C. (64° F.) during N1-N2 sleep, 15.56° C. (60° F.) during N3 sleep, 18.89° C. (66° F.) during REM sleep, and 20° C. (68° F.) to wake the user.
In still another embodiment, temperature modulation cycles are used to reduce sleep disruptions due to multiple sclerosis (MS). In MS, core temperature and extremity temperature management is not consistent. As a result, a warm to sleep and warm to wake is suggested. In one example, the surface temperature is 37.78° C. (100° F.) at the start of a sleep period, 21.11° C. (70° F.) during N1-N2 sleep, 20° C. (68° F.) during N3 sleep, 26.67° C. (80° F.) during REM sleep, and 37.78° C. (100° F.) to wake the user.
In yet another embodiment, temperature modulation cycles are used to support users with alternative sleep cycles. An alternative sleep cycle is when a user changes to a multiple phase sleep cycle in a 24 hour cycle (e.g., biphasic, segmented, polyphasic sleep). In one example, the surface temperature is 21.11° C. (70° F.) at the start of a sleep period, 17.78° C. (64° F.) during N1-N2 sleep, 16.67° C. (62° F.) during N3 sleep, 19.44° C. (67° F.) during REM sleep, and 21.11° C. (70° F.) to wake the user. This program can repeat for multiple, evenly spaced sleep blocks or be used in a longer block of 4-5 hours. For a short 30 minute block, the temperature drops (e.g., 0.278° C./minute (0.5° F./minute) or greater).
In one embodiment, temperature modulation cycles are used to reduce bed sores. The temperature modulation cycles alternate cooling and heating based on automated collection of risk factors, including temperature, surface area pressure, and moisture (e.g., sweat). In another embodiment, temperature modulation cycles are prescribed by a sleep specialist or physician base on a particular health condition of a user.
The custom programs 741 are sleep settings defined by the user. In one example, the user creates a custom program by modifying a predefined program (e.g., the weight loss program above) to be 1.11° C. (2° F.) cooler during the N3 stage. In another example, the user creates a custom program by modifying a predefined program (e.g., the weight loss program above) to have a start temperature of 37.78° C. (100° F.). The custom programs 741 allow a user to save preferred sleep settings.
The remote server 708 includes global historical subjective data 746, global historical objective data 748, global historical environmental data 750, global profile data 752, a global analytics engine 754, a calibration engine 756, and a simulation engine 758. The global historical subjective data 746, the global historical objective data 748, the global historical environmental data 750, and the global profile data 752 include data from multiple users.
The system components include a mattress pad 11 with adjustable temperature control, a mattress with adjustable firmness 768, a mattress with adjustable elevation 770, an alarm clock 772, a thermostat to adjust the room temperature 774, a lighting system 776, a fan 778, a humidifier 780, and/or a dehumidifier 782.
The body sensors 702, the environmental sensors 704, the remote device 511 with local storage 706, the remote server 708, and the system components 710 are designed to connect directly (e.g., USB or equivalent) or wirelessly (e.g., Bluetooth, Wi-Fi, ZigBee) through systems designed to exchange data between various data collection sources.
At the start of a sleeping period, a program is selected that provides optimized values for the sleeping period. The program is preferably a predefined program or customized program based on user preferences. In one embodiment, the optimized values include, but are not limited to, sleep stage (e.g., awake, Stage N1, Stage N2, Stage N3, REM Sleep), breath rate, heart rate, brain waves (e.g., beta waves, alpha waves, theta waves, delta waves), blood oxygen rate, body temperature, and/or settings for the system components 710.
As shown in
The global analytics engine 754 analyzes differences between the predicted values and optimized values. If the difference between the optimized values and the predicted values is greater than a threshold, then the simulation engine 758 determines optimized values of the monitored sleep system 700 based on the real-time data and user preferences. The global analytics engine 754 determines whether a change in parameters of the system components 710 is necessary to optimize sleep based on the output of the simulation engine 758. If a change in parameters is necessary, the new parameters are transmitted to the mobile application on the remote device 511 and then to the system components 710. The calibration engine 756 then updates the virtual model with the new parameters. Thus, the system autonomously optimizes the sleep system (e.g., surface temperature) without requiring input from a user.
The sleep system 700 includes a virtual model of the sleep system. The virtual model is initialized based on the program selected. The virtual model of the sleep system is dynamic, changing to reflect the status of the sleep system 700 in real time or near-real time. The virtual model includes information from the body sensors 702 and the environmental sensors 704. Based on the data from the body sensors 702 and the environmental sensors 704, the virtual model generates predicted values for the sleep system 700. A sleep stage (e.g., awake, Stage N1, Stage N2, Stage N3, REM sleep) for the user is determined from the data from the body sensors 702.
The sleep system 700 is monitored to determine if there is a change in status of the body sensors 702 (e.g., change in body temperature), the environmental sensors 704 (e.g., change in room temperature), the system components 710 (e.g., change in temperature of mattress pad), or sleep stage of the user. If there is a change in status, the virtual model is updated to reflect the change in status. Predicted values are generated for the sleep system 700. If a difference between the optimized values and the predicted values is greater than a threshold, a simulation is run on the simulation engine 758 to optimize the sleep system 700 based on the real-time data. The simulation engine 758 uses information including, but not limited to, global historical subjective data 746, global historical objective data 748, global historical environmental data 750, and/or global profile data 752 to determine if a change in parameters is necessary to optimize the sleep system 700. In one example, the temperature of the mattress pad 11 is lowered to keep a user in Stage N3 sleep for a longer period of time.
In step 2214, predicted values for the monitored sleep system 700 are generated based on the current, real-time status of the monitored system. In one embodiment, the predicted values include, but are not limited to, sleep stage (e.g., awake, Stage N1, Stage N2, Stage N3, REM Sleep). In step 2216, the optimized values loaded in step 2204 are compared with the predicted values obtained in step 2214.
Accordingly, meaningful predicted values based on the actual condition of monitored sleep system 700 are generated in step 2214. These predicted values are then used to determine if further action should be taken based on the results of the comparison in step 2216. For example, if it is determined in step 2218 that the difference between the predicted values and the optimized values is less than or equal to a threshold, then a do not calibrate instruction is issued in step 2220. If the difference between the real-time data and the predicted values is greater than the threshold, as determined in step 2218, then an initiate simulation command is generated in step 2222.
In step 2224, a function call to the simulation engine 758 is generated in response to the initiate simulation command. The simulation engine 758 selects optimized values for the sleep system 700 in step 2226. These optimized values are updated on the global analytics engine 754 in step 2204. Based on the output of the simulation engine 758, the global analytics engine 754 determines if the optimized values require a change in parameters of the sleep system 700 (e.g., temperature of mattress pad, room temperature, lighting, mattress firmness, mattress elevation) in step 2228. In a preferred embodiment, the simulation engine 758 uses the global historical subjective data 746, the global historical objective data 748, the global historical environmental data 750, and the global profile data 752 to determine if the change in parameters is necessary. If a change in parameters is not necessary, a do not calibrate instruction is issued in step 2230. If a change in parameters is necessary, the new parameters are transmitted to the remote device 511 in step 2232. The remote device 511 transmits the new parameters to the system components 710 in step 2234.
The calibration engine 756 updates the virtual model in step 2212 based on the real-time data and the new parameters. Predicted values are then generated in step 2214. In this manner, the predicted values generated in step 2214 are not only updated to reflect the actual status of monitored sleep system 700, but they are also updated to reflect natural changes in monitored system 700 as the user moves through the sleep cycle. Accordingly, realistic predicted values can be generated in step 2214.
As previously mentioned, the least one remote device 511 preferably has a user interface 766 (e.g., a mobile application for a smartphone or tablet) that allows the sleep system 700 to adjust the parameters of the sleep system. The parameters of the sleep system (e.g., target temperatures of a mattress pad) can be manipulated through the sleeping period using a predefined program or a customized program based on user preferences to produce a deeper, more restful sleep.
Because the target temperatures may be set at any time, those target temperatures may be manipulated through the sleeping period in order to match user preferences or a program to correlate with user sleep cycles to produce a deeper, more restful sleep.
In one embodiment, the mobile application measures a time when a user began attempting to sleep (TATS), a TATS start time, a TATS end time, a time in bed (TIB), a TIB start time, and/or a TIB end time. The mobile application calculates a total TATS duration based on the TATS start time and the TATS end time. The mobile application also calculates a total TIB duration based on the TIB start time and the TIB end time. In one embodiment, the TATS start time, the TATS end time, the TIB start time, and/or the TIB end time are indicated by the user (e.g., by pressing a button in the mobile application). Alternatively, the TATS start time, the TATS end time, the TIB start time, and/or the TIB end time are determined by sensors. In one example, the TATS start time is determined by a user's eyes closing while in bed. In another example, the TATS end time is determined by increased motion as measured by a movement sensor and/or opening of the eyes. In yet another example, the TIB start time is determined by sensors indicating a user is horizontal and/or bed or room sensors indicating the user is in bed. In still another example, the TIB end time is determined by sensors indicating a user is not horizonal and/or bed or room sensors indicating the user is not in bed.
The mobile application is operable to determine whether a user is awake or asleep. The state of wakefulness (i.e., “awake”) is characterized by cognitive awareness and/or consciousness, responsiveness to environmental cues, sustained movement detected by a movement sensor, beta and/or alpha waves as detected by EEG, increased heart rate, increased respiration, increased blood pressure, increased electrodermal activity, increased body temperature, open eyes, voluntary eye movements, and/or increased EMG on the chin. The state of sleep (i.e., “asleep”) is characterized by loss of alertness and/or consciousness, lack of response to environmental cues, lack of movement, reduction in alpha waves as detected by EEG, increased theta and delta waves as detected by EEG, decreased heart rate, decreased respiration, decreased blood pressure, decreased body temperature, closed eyes, eye twitches, and/or decreased oxygen saturation.
In a preferred embodiment, the mobile application is operable to measure an initial sleep onset time and/or a final awakening time. The initial sleep onset time is a first occurrence of sleep after the TATS start time. The final awakening time is a time immediately after the last occurrence of sleep before the TATS end time. In one embodiment, the mobile application calculates a latency to sleep onset as the duration of a time interval between the TATS start time to the initial sleep onset time. In another embodiment, the mobile application calculates a latency to arising as the duration of a time interval between the final awakening time to the TATS end time. In a preferred embodiment, the mobile application is operable to calculate a sleep efficiency percentage. In one embodiment, the sleep efficiency percentage is defined as the total sleep time divided by the total TATS duration. In an alternative embodiment, the sleep efficiency percentage is defined as the total sleep time divided by the total TIB duration.
In one embodiment, the mobile application is operable to determine a total sleep period duration, a total sleep time, a sleep maintenance percentage, a total wakefulness duration, a wakefulness duration after initial sleep onset, a total number of awakenings, an awakening rate per hour, and/or a sleep fragmentation rate.
In another embodiment, the mobile application is operable to determine REM sleep, N1 sleep, N2 sleep, and/or N3 sleep. REM sleep is characterized by low-voltage, mixed-frequency EEG activity with less than 15 seconds of alpha activity, saw-tooth theta EEG activity, rapid eye movements, and/or decreased or absent EMG activity on the chin. N1 sleep is characterized by low-voltage, mixed-frequency EEG activity with less than 15 seconds of alpha activity in a 30-second epoch, no sleep spindles or K complexes, possible slow rolling eye movements, and/or diminished EMG activity on the chin. N2 sleep is characterized by sleep spindle and/or K complex activity, absence of eye movements, and/or diminished EMG activity on the chin. N3 sleep is characterized by high amplitude (e.g., greater than 75 μV peak-to-peak), slow wave (e.g., frequency of 4 Hz or less) EEG activity. In yet another embodiment, the mobile application is operable to calculate REM sleep duration, percentage, and latency from sleep onset; N1 sleep duration, percentage, and latency from sleep onset; N2 sleep duration, percentage, and latency from sleep onset; and/or N3 sleep duration, percentage, and latency from sleep onset.
Alternatively, the calculations and determining of sleep states described above are determined over the network on a remote server. In one embodiment, the calculations and determining of sleep states are then transmitted to at least one remote device.
The home screen includes a graph of the number of hours a user slept versus dates. In this example, the graph provides the number of hours a user slept for the previous 10 days. In one embodiment, the number of hours a user slept for a day is obtained from a wearable device (e.g., Fitbit, Jawbone UP, Misfit, Apple Watch, Nokia Steel, Nokia Go). Alternatively, the user manually enters a time the user went to sleep and a time the user woke up.
The home screen also provides a current snapshot of the user's daily health information. The user's daily health information includes, but is not limited to, the number of steps the user has taken, the percentage of fitness goals achieved, the number of calories consumed by the user, and the amount of water consumed by the user. This information is preferably updated in real time or near-real time by the mobile application. In one embodiment, this information is manually entered into the mobile application. Alternatively, this information is obtained from third-party applications (e.g., Fitbit, Jawbone, Misfit, MyFitnessPal, Apple Health, Health Mate).
The home screen allows the user to set a smart alarm (e.g., 6:10 AM). The smart alarm increases the surface temperature of the mattress pad sufficiently over a period of time to allow the user to emerge out of the last sleep cycle. The speed of awakening is based on the sleep cycle information. The speed of temperature increase is faster (e.g., 0.278° C./minute (0.5° F./minute)) if a new cycle is just beginning. The speed of temperature increase is slower (e.g., 0.056° C./minute (0.1° F./minute)) if the user is just coming out of the bottom of a sleep cycle. In one embodiment, the mobile application uses active data collection of the user's vital signs, including, but not limited to, heart rate, breath rate, blood oxygen level, brain waves, and/or skin temperature, to determine the speed of awakening.
The sleep screen also has a button for a smart alarm. This allows the mobile application to adjust the settings of the mattress pad to wake the user at an optimal time within a sleep cycle. As previously described, gently awakening the user by increasing the temperature prevents sleep inertia. The sleep screen also has a button for tracking motion of the user. Further, the sleep screen also has a button for tracking sound of the user.
In another embodiment, the mobile application notifies the user that water treatment or purification is required. In another embodiment, the mobile application automatically schedules water treatment or purification (e.g., automatically turning on the UV light for water treatment) at designated time intervals.
Most individuals adopt a monophasic sleep pattern (e.g., sleeping 6-8 hours at a time). Non-monophasic sleep occurs when an individual adopts a biphasic or polyphasic sleep pattern. A biphasic sleep pattern is when the individual sleeps twice per day. Typically, this consists of a shorter rest (e.g., “siesta”) during the day and a longer sleep period during the night. A polyphasic sleep pattern (e.g., Everyman, Uberman, Dymaxion, Dual Core) consists of multiple sleeps throughout the day, generally ranging from 4 to 6 periods of sleep per day.
