1. Field of the Invention
The present invention is directed to methods for monitoring user or patient parameters, and more particularly to methods that use a user activity manager, feedback control in combination with a monitoring device with a unique user ID and a telemetry system to provide for monitoring a user's activities using one or more analysis tools and provide feedback.
2. Description of the Related Art
Patient monitoring was accomplished by electronic equipment maintained at the user's bedside. Vital signs derived from physiological waveforms were monitored with the bedside equipment and alarms were generated if predetermined limits were exceeded by the vital signs. This bedside monitoring equipment became larger, more complex and expensive as each bedside unit undertook to monitor more physiological data and provide more sophisticated displays, e.g. color, more and better communications and more in-depth analysis of the data, such as calculation of vital signs and trends which required memory and processing capability. The provision of such units at each appropriate user bedside introduces considerable additional expense to the hospital user care costs.
With the introduction of bedside monitoring units, attempts were made to provide a measure of remote monitoring by transmitting analog waveforms of physiological data from the bedside unit to equipment at a central station such as a nurse's station. Subsequently remote monitoring efforts included analog waveforms plus digital representations for display. Both the bedside and remote monitoring activity acted to give alarms upon sensing an abnormal condition and to store data and analyze data to obtain vital signs and trends. But these systems are basically one-way systems reporting physiological data from the user. There is no communication with the user as a part of an interactive integrated system.
Telemetry systems can be implemented to acquire and transmit data from a remote source. Some telemetry systems provide information about a user's activities.
It is becoming commonplace to use wireless packet data service networks for effectuating data sessions with. In some implementations, unique identifications (ID) need to be assigned to the devices in order to facilitate certain aspects of service provisioning, e.g., security, validation and authentication, et cetera. In such scenarios, it becomes imperative that no two devices have the same indicium (i.e., collision). Further, provisioning of such indicia should be flexible so as to maintain the entire pool of indicia to a manageable level while allowing for their widespread use in multiple service environments.
Medical telemetry systems may comprise an alarm adapted to identify high risk users and/or users requiring special assistance. Some medical procedures and diagnostic examinations require the removal of any telemetry system components attached directly to a user. One problem with conventional medical telemetry systems is that the process of removing telemetry system components for purposes of performing a medical procedure or diagnostic examination can generate a false alarm. False alarms unnecessarily tax hospital resources and interfere with the working environment.
There is a need for methods using telemetry devices configured to be used for user lifestyle management, monitoring user behavior, user activity and habits and health monitoring. There is a further need for wireless communication methods with monitoring devices that have sensors used for a monitoring user behavior, user activity and habits and health monitoring, analysis of the monitoring followed by feedback alerts.
An object of the present invention is to provide methods that provide tools for analysis and feedback for medical and lifestyle management.
Another object of the present invention is to provide methods for medical and lifestyle management using user habit information or user monitoring, analysis tools and feedback.
A further object of the present invention is to provide methods for medical and lifestyle management using monitoring devices with sensors that monitor one or more of a user's activities, behaviors and habit information, the use of analysis tools followed by providing user feedback.
Still another object of the present invention is to provide methods for medical and lifestyle management using one or more contexts selected from at least one of, time, location, type of user activity, duration of user activity and a status of the user activity, analysis tools used to provide user feedback.
Yet another object of the present invention is to provide methods that use an activity manager and feedback to manage and monitor user lifestyle or medical conditions in response to receiving information for a monitoring device with sensors that monitor one or more of a user's activities, behaviors and habit information, following by using analysis tools in response to the monitoring.
These and other objects of the present invention are achieved in a method for using telemetry data based on user habit information or user monitoring. One or more sensors of a monitoring device detects or measures user information selected from of at least one of, a user's activities, behaviors and habit information, and a user's health. The user information is received at a telemetry system with a database. One or more analysis tools at the telemetry system are used for the analysis. Analysis information is produced that is sent to the monitoring device.

Classifiers are functions that can be tuned according to examples. A wide range of classifiers are available, each with its strengths and weaknesses. The most widely used classifiers are neural networks, support vector machines, k-nearest neighbor algorithms, Gaussian mixture models, naive Bayes classifiers, and decision trees. Expert systems apply reasoning capabilities to reach a conclusion. An expert system can process large amounts of known information and provide conclusions based on them.
A case-based reasoning system stores a set of problems and answers in an organized data structure called cases. A case based reasoning system upon being presented with a problem finds a case in its knowledge base that is most closely related to the new problem and presents its solutions as an output with suitable modifications. A behavior based AI is a modular method of building AI systems by hand. Neural networks are trainable systems with very strong pattern recognition capabilities.
Fuzzy systems provide techniques for reasoning under uncertainty and have been widely used in modern industrial and consumer product control systems. An Evolutionary Computation applies biologically inspired concepts such as populations, mutation and survival of the fittest to generate increasingly better solutions to the problem. These methods most notably divide into evolutionary algorithms (e.g., genetic algorithms) and swarm intelligence (e.g., ant algorithms). Hybrid intelligent systems are any combinations of the above. It is understood that any other algorithm, AI or otherwise, may also be used.

For purposes of this disclosure, monitoring data is defined to include data acquired during the process of monitoring or evaluating a predefined characteristic. The user activity data tracks data from the sensors 14 is transferred to the receivers 34 via the wireless connections 38 represented by a dashed line.
A network of receivers 34 transfers the user activity and/or tracking data to system server 16 via connection 50. System server 16 includes a processor 52 configured to process the user data in a known manner. For example, the processor 52 may convert raw user data acquired by the sensors 14 into more conveniently readable data.

In addition to insuring authorized access, this process also insures that the data itself is correct. The longer the polynomial sequence used, the greater the security.
In one embodiment, spread spectrum or other RF transmission is used and can include programming to determine that the frequency or spread spectrum code is unique to the area. If a spread spectrum code, system code, or frequency channel is found to be occupied at a future time of use. Re-programming of the user monitoring device 10 is then done with a new, unused spread spectrum code or system code or frequency channel can be selected, or, in the alternative, CPU 20.

In one embodiment, the position signal transmitted by the remote sensor 14 can also include an emergency code. For example, in the event of an emergency, such as a medical emergency or otherwise, a user may press a “panic button” that can be on the user monitoring device 10 or by use of a user's mobile device. Pressing the panic button may cause mobile device 74 to transmit an emergency signal to a cell site 76 where the emergency signal is relayed to server 16. In response, server 16 can transmit Doppler information regarding in-view satellites, a fix command and a time trigger signal to the user monitoring device 10.
When the location of the user monitoring device 10 has been determined, software running on server 16 configures server 16 such that a call or other signal is sent to a local emergency operator in the vicinity of remote sensor 14. When the call or signal is received at the emergency operator station, the location of remote sensor 14 is transmitted and displayed. In some cases, where separate panic buttons are available for identifying medical, police, fire or other types of emergencies, the nature of the emergency is also displayed for the emergency operator. Based on this information, the emergency operator can initiate an emergency response by providing the location of remote sensor 14 to the required emergency service (police, fire department, ambulance service, etc.). In other embodiments, instead of or in addition to a position report for the remote sensor 14, the emergency operator may also be provided with information which identifies an emergency response vehicle in close proximity to remote sensor 14.

As non-limiting examples, and as illustrated in
The acoustic transducer 80 may include a microphone, a low-pass filter, a gain amplifier, and a threshold comparator. The acoustic transducer 80 may include an omnidirectional microphone, although any other suitable acoustic transducer device would suffice. The microphone may be a surface mount MEMS device that has a frequency range of 100 Hz to 10 kHz. A single MCP602 operational amplifier is used on the acoustic sensor to amplify and low-pass filter the acoustic signal from the microphone. Another operational amplifier is used to generate a voltage reference used for single biasing and detection. The microphone output is biased to the midway point between the circuit supply voltage and ground to allow for both positive and negative signal swings. The biased signal is filtered with a second order low-pass Butterworth filter to remove upper frequency noise. It is then amplified with an adjustable gain that is controlled by a digital resistor potentiometer. This digital resistor operates on an I2C bus and is controlled by the microprocessor 84. Lastly, the amplified acoustic signal is threshold detected against a static voltage to detect sufficiently large acoustic signals. The digital output of the threshold detector is connected to the microprocessor 84 for processing.
The magnetic transducer 82 can include a magnetic sensor integrated circuit, a differential instrumentation amplifier, a low-pass filter, two gain amplifiers, and a threshold detector. The magnetic transducer 82 may include an NVE AA002-02 GMR (giant magneto resistive) field sensor, although any suitable magnetic sensor would suffice. This sensor has a saturation field of 15 Oe, a linear range of 0 to 10.5 Oe, and a sensitivity of 3 mV/V/Oe. Two MCP602 CMOS operational amplifiers are used on the magnetic sensor to amplify and low-pass filter the analog output signal. An INA122UA instrumentation amplifier is used as a difference amplifier for the differential output from the magnetic sensor. The magnetic sensor IC can be based on Spintronics technology. Its output includes a differential voltage pair proportional to the detected magnetic field. The differential voltage pair is amplified and converted to a single voltage by the instrumentation amplifier. The AC-coupled signal is then amplified and filtered with a low-pass filter to remove upper frequency noise and boost the low-voltage signal output. The signal is amplified a second time by an adjustable gain controlled by a digital resistor similar to the acoustic sensor. Lastly, the amplified magnetic signal is threshold detected against a static voltage, to detect sufficiently large changes in magnetic fields. The digital output of the threshold detector can be connected to the microprocessor 84 for processing.
A DS1803E-010 digitally controlled 10 kOhm variable resistor can be used in both the acoustic and magnetic sensor circuits. It is used to adjust the gain of one gain stage in each circuit. The digital resistor is controlled through an I2C interface. A LMV393IPWR comparator is also used in both the magnetic and acoustic sensor circuits for determining when a sufficiently strong sensor signal has been detected. It compares the analog sensor signal against the voltage reference and its output is tied to the microprocessor 84 for data collection.
The thermal transducer 78 may include a Burr Brown TMP 100NA/250 12-bit digital temperature sensor, although any suitable thermal sensor would suffice. The digital temperature sensor has an operating range of −55 to +120.degree C., an accuracy of 0.5.degree C. and a maximum resolution of 0.0625.degree C.
Even though it is a 12-bit sensor, suitable results are achieved with only 9-bit conversions with only the 8 most significant bits used. The sensor has an I2C interface and is normally kept in sleep mode for low power operation. When directed by the microprocessor 84, the thermal transducer can perform a 9-bit temperature conversion in 75 milliseconds.
The RF transceiver 86 may include an RF Monolithic DR3000 transceiver, although any suitable transceiver or separate transmitter and receiver 34 would suffice. This transceiver 86 allows for both digital transmission and reception. The transceiver 86 can have an operating frequency of 916.5 MHz and is capable of baud rates between 2.4 kbps and 19.2 kbps. It can use OOK modulation and has an output power of 0.75 mW. It also can use digital inputs and outputs for direct connection with the microprocessor 84. The transceiver 86 can use an antenna 92 (
The IRDA transceiver 88 may include a Sharp GP2W0110YPS infrared transceiver, although any suitable IRDA compliant infrared transceiver would suffice. This transceiver 88 can be IRDA v1.2 compliant and in one embodiment has an operating range of 0.7 meters. In one embodiment, it is capable of 115.2 kbps data speeds.
The RF backscatter transmission device 90 may include circuitry available from Alien Technology (of Morgan Hill, Calif.) for receiving and transmitting signals via RF backscatter. Battery 24 may be a 3.6 volt 1/2 AA lithium battery with a capacity of 1.2 amp hours. The battery 24 can be a power source 24 that can include a Texas Instruments TPS76930DBVT voltage regulator to regulate the output signal to 3 volts and with a maximum current of 100 mA. The voltage regulator can include a LDO.
The RF backscatter transceiver 86 in the user monitoring device 10 communicates with an RF backscatter reader 94 such as a class 3 reader from Alien Technology. The reader 94 transmits data to the backscatter transceiver 90 of the user monitoring device 10 by broadcasting encoded RF pulses and receives data back from the transceiver 86 by continually broadcasting RF energy to the sensor 10 and monitoring the modulated RF reflections from the sensor 10.
The RF backscatter transceiver 90 can include a printed circuit board (PCB) patch antenna for RF reception, and RF modulation, a Schotky diode detector circuit, a comparator circuit for signal decoding, and a logic circuit for wake-up. The logic circuit monitors the incoming data, and when an appropriate wake-up pattern is detected, it triggers the microprocessor 84 so that data reception can begin. In one embodiment, the reader 94 has an operating frequency between 2402 MHz and 2480 MHz, and uses frequency hopping in this band to reduce noise interference. A modulation method used by the reader 94 can be On-Off Keying (00K). In one embodiment, the transmission power is 1 watt. The operation of the reader 94 may be controlled by an external computer (not shown) as directed by Labview software via a RS-232 serial link.
The RF transceiver 86 can communicate with an external RF transceiver 96 such as a DR3000 transceiver from Radio Monolithics, Inc. In one embodiment, it operates at 916.5 MHz, uses OOK modulation, has a communication range of 100 meters line of sight, and a baud rate of 19.2 kbps. The active RF antenna 92 can be a quarter-wavelength monopole made from a guitar G-string and appropriate matching circuitry. Two control lines from the microprocessor 84 can be used to select the mode of operation, choosing from transmit, receive, and sleep. The active RF receiver 34 consumes the most power in receive mode compared to the other two communication links.
The IRDA transceiver 88 of the user monitoring device 10 can communicate with an external IRDA transceiver 100 that may be identical to the IRDA transceiver 88. Alternatively, the IRDA transceiver 100 can be one such as is provided in most personal digital assistants (PDA) as well as many other consumer devices. The IRDA communication link follows the standard IRDA signal and coding protocol and is modeled after a standard UART interface. In one embodiment, the IRDA transceiver 88 is capable of data speeds less than 115.2 kbps, and may only have a range of 0.7 meters for transmission. One advantage of the IRDA communication link is that it does not require any of the RF spectrums for operation, but it typically does require line-of-sight communication.
When any one of the transceivers 86, 88 and 90 on the user monitoring device 10 detect the beginning of valid data on their respective communication link, all other transceivers are disabled, thereby preventing the corruption of incoming data with the noise or partial data packets on the other communication links. However, if the data on the active transceiver proves to be erroneous, the other transceivers will be re-enabled if appropriate to allow normal operation to continue. If the data received by the active transceiver is valid, however, the other transceivers will remain disabled for several hundred milliseconds longer in the high probability that the next data packet will be transmitted on the same communication link. If, after this extended delay, no additional packets are received, then the other transceivers will be re-enabled as appropriate.
In one embodiment, the active RF protocol has no wake-up or synchronization packets, and the packets sent to and from the sensor are identical. In one embodiment, the format of an active RF packet is shown in
Furthermore, the encoding scheme for the three symbols is shown in
The IRDA communication link can follow the standard IRDA protocol for bit encoding and UART protocol for byte transmission. Packets transmitted on the IRDA link can contain no preamble or framing bits, but they do have a header that contains two bytes. The first byte is an ASCII “I” which denotes the beginning of a valid IRDA packet. The second byte equals the number of preceding bytes in the packet. This value is used by the receiver 34 to determine when the entire packet has been received and processing of information can begin. The packet structure is shown in
The data bytes contained in a packet transmitted to the sensor 10 through any of the communication links conform to a packet format. The CMD section of a packet is a single byte that identifies the type of packet being sent. The CMD byte appears above the beginning and end of the packet and the two must be identical. The reason for including the redundant byte is to further eliminate the chance of a packet's CMD identifier being corrupted at the receiver 34, even if the CHECKSUM is correct.
The PAYLOAD contains all of the data that must be sent to, or returned from, the sensor. The PAYLOAD is broken down into individual bytes with the overall number of bytes and their content dependent on the type of packet being sent.
The CHECKSUM is a 16-bit CRC that is performed on all bytes in the data packet excluding the end CMD byte in packets generated by the external device. The CHECKSUM is sent most significant byte first.
The transceivers 86, 88 and 90 may be required to communicate over a greater distance than do the components described herein. Upgrading these components to be suitable for longer distance transmission is considered to be within the spirit of this invention. The type of transducer is not limited to the specific transducer types described herein. In addition, the logic described herein for arbitrating between which communication device to use to communicate with the outside world and which sensor data to provide at what time is but one possible approach to arbitration logic within such a remote sensor 10.
In one embodiment, illustrated in
In one embodiment, one or more of sensors 14 can be a lifestyle sensor. For example, the sensor 14 can be a physiological sensor such as a heart rate sensor, body temperature sensor, caloric sensor, or the like. Another example of a sensor is a pedometer. It should be noted that any sensor or device capable of taking measurements is applicable to the present invention. These sensors can be embedded, for example, in clothing and/shoes or can be stand-alone items. One specific example of these types of sensors is a sensor that is embedded in running shoes. As a user walks or runs, the sensor 14 monitors various functions such as speed, stride length, body functions (heart rate, temperatures, hydration, and the like), and the like.
This information can then be relayed back to the dynamic activity manager 218 if desired. A web service 224 can be any type of service subscribed to by the user over the Internet. For example, a user can be subscribed to a weather service that is used by the dynamic activity manager 218 when monitoring an activity such as running. The dynamic activity manager 218, identifier enable items, including but not limited to RFID enabled items 220, sensors 14, and Network System 224 are discussed in greater detail below.
The dynamic activity manager 218 provides management for managing user lifestyle activities and is preferably included as part of the telemetry system 32. In one embodiment, the activity manager 218 is in communication to a user interface 202, which can be at the monitoring device 10, for allowing a user to enter information associated with an activity that the user wants managed and/or monitored. As a non-limiting example,
In one embodiment, a name entry field 302 can be used that allows the user to enter the name of an existing activity or the field 302 can be a drop down box including existing activities. In another embodiment, the monitoring device 10 or the telemetry system 32 can perform this activity and function.
A user may also want the activity manager 218 to track specific items associated with the activity. For example, with respect to the running activity, a user may want to have her running shoes and headphones tracked to ensure that she has these items when she begins the activity. This information can be entered in the items to be tracked field 312. The tracking process is discussed in further detail below. The user may also want to use specific sensors 14 during the activity such as sensors 14 in the running shoes and a heart rate monitor. The sensor IDs or names can be added into the sensor field 314. A user can also configure the sensor parameters that she wants used during the activity. Alternatively, the sensor parameters can be transparent to a user. For example, the parameters can be pre-populated based on success of data collection of prior activity history. This information is entered in a sensor parameter field 316. In addition to having items tracked and sensors 14 monitored during the activity, the user may want to associate a web service with the activity.
For example, a user may want to associate a weather service with the running activity so that the activity manager 218 can automatically and dynamically adjust settings on the sensors 14; determine to track different items; and the like. For example, the activity manager 218 can monitor the web service to determine if the weather is sunny, cloudy, raining, or the like. If the weather is sunny, the activity manager may determine that a first pair of running shoes, sun glasses, and the like need to be tracked. On the other hand, if the weather is raining, the activity manager 218 can determine not to track sunglasses and to track a second pair of running shoes. It should be noted that the term “tracked” as used throughout this discussion refers to use of the ID of the monitoring device.
Alternatively, a user can setup rules that allow a web service to perform a function based on contexts. For example, if the weather is rainy, a user can have a rule setup that has a web service make a reservation at an indoor track.
It should also be noted that the user interface of
Referring again to
Based upon the received activity information, the activity manager 218 creates activity profiles 210, 212 that are stored in an activity management database 208.
Also,
In the example of
For example, if the user has defined a “running” activity on two different days at two different times and at two different locations, the activity manager 218 can still refer to the “running” activity profile and use the information included therein for the two instances of the “running” activity. Therefore, the activity manger 218 monitors both the calendar 402 and the activity management database 208. However, the activity profiles 210 can also include time and location contexts as well. In this example, a separate activity profile is stored in the activity management database for each instance of an activity.
Returning now to
In one embodiment, the dynamic activity manager 218 is communicatively coupled to a GPS module 246 and a display 244. The GPS module can be used by the dynamic activity manager 218 to determine the location of the monitoring device 14. The display 244 can be used for, among other things, to display data/information, visual alerts to a user.
As discussed above, the activity manager 218 manages and monitors identifier, enabled items 220, sensors 14, and Network Systems 224 associated with a user activity. The identifier enabled items 220 can be any item that is coupled to an identifier or other communication tag. The activity manager 218 monitors identifier enabled items 220 via an identifier enabled item monitor 206, herein referred to as the “identifier monitor” 206. The identifier monitor 206, in one embodiment, can be an identifier transceiver embedded with monitoring software or can be a separate monitoring software module coupled to an identifier transceiver.
The identifier monitor 206 can be configured by the user to automatically start monitoring for items associated with an activity or to continuously monitor for identifier enabled items 220. For example, when the activity manager determines, based on a time context and/or a location context associated with an activity, that it is time for an activity to start, the activity manager 218 can begin monitoring for associated identifier enabled items 220. For example, if the activity manager 218 determines that the running activity is about to begin, the identifier monitor analyzes the activity profile 210 to determine what items are needed for the activity. The identifier monitor 206 then determines if items such as running shoes and heart beat monitor are present. In other words, the identifier monitor 206 determines if an identifier signal from the running shoes and the heartbeat monitor has been detected. The activity manager 218 can then visually, audibly, and/or tactilely notify the user of the presence or non-presence of the items 220.
Based on the activity profiles 210, calendar 204, and/or an internal clock the activity manager 218 can determine that the user has not left for work, to go running, or whatever the activity may be. For example, a user can have a calendar entry or an activity defined for “leave for work”, which begins at 8:00 a.m. Therefore, if the time is 7:30 a.m. the activity manager 218 can determine that the user has not left for work. In another example, a user can have an activity defined for “running”. The activity manager 218 can detect that the user has left the house, entered his/her car or the like either by passing an identifier sensor at a door or via GPS and analyzes the activity profiles 210 accordingly.
The activity manager 218, based on activity profiles and/or calendar events determines that the user is going straight from work to her running activity. Therefore, the activity manager 218 monitors for the items associated with the running activity. The activity manager 218 then notifies the user if these items have been protected
In addition to monitoring for associated identifier enabled items 220 when an activity is to begin, the activity manager 218 manages sensors 14 associated with the activity. For example, when an activity is about to begin, the activity manager 218 analyzes the activity profile 210 associated with the activity and identifies the sensors 14 associated with the activity. If the sensor 14 has not been initialized, the activity manager 218 initializes the sensor 14 using the configuration parameters in the activity profile 210. For example, the sensors 14 and the monitoring device 14 can communicate via a communication manager 212 within the activity manager 218. The sensors 14 and the monitoring device 14 can communicate using a wireless connection such as BLUETOOTH®, Zigbee, or the like. In one embodiment, the dynamic activity manager also includes a data fusion module 214 for performing data fusion with respect to health and fitness information monitored by the sensors 14.
At time T3 the activity manager 218 pings the sensors 14 to determine if they have been initialized. If the sensors 14 have not been initialized the activity manager 218 identifies that configurations parameters of the sensor from the activity profile 210 and initializes the sensors 14 accordingly. The sensors 14, at time T4, send a ready response to the activity manager 218. At time T5 the activity manager 218 begins collecting data from the sensors 14. The activity manager 218, at time T6, determines that the activity has completed. At time T7, the activity manager 218 displays collected data from the sensors 14 to the user via the user interface 202.
In another embodiment, a user can configure the activity manager 218 to only collect specific data from a sensor 14 or not all data. Also, the activity manager 218 does not have to communicate with a sensor 14 during an activity. For example, a user may have forgotten the monitoring device 10 at her house. The application manager 218 determines that an activity is starting, but sensors 14 are not in the vicinity. When sensors 14 come back into range with the monitoring device 14, e.g., the user comes home from running, the activity manager 218 queries the sensor 14 for the data collected during the activity. In one example, the sensors 14 collect data continuously and in another example the sensor 14 only collects data during scheduled activities. For example, a user's watch may have a biometric sensor that collects data throughout the day. However, the user may only be concerned with plotting data during athletic activities such as bicycling. Therefore, the activity manager 218 can query the sensor 14 for data only collected during a bicycling activity. In the above embodiments, the sensors include memory for storing data.
As illustrated in
The activity manager 218 can also make dynamic decisions for when to monitor and/or manage an activity. For example, a user has an activity defined for “pick up dry-cleaning” at 3:00 p.m. However, at 12:00 p.m. the user runs errands and is approaching the dry cleaners. The activity manager 218 can detect the location of the user via GPS and determines that the user is near the dry cleaners. The activity manager then determines that the user needs to pick up the dry cleaning and prompts the user to pick up the dry cleaning even though the time is prior to the 3:00 p.m. scheduled pickup time.

In another embodiment, feedback system or subsystem 710 can generate and communicate signals 714 for video/audio data communication to the monitoring device user or patient.
In another embodiment feedback system or subsystem 710 can generate and communicate monitoring device user or patient control data (“PCD”) 716 to the monitoring device user or patient. In another embodiment, feedback system or subsystem 710 generates and communicates sensing control data (“SCD”) 718 to a feedback system 720 associated with the monitoring device 10 for providing feedback to the monitoring device user or patient. Signals and data 712 through 718 can be converted into signals for executing feedback information, visual, audio and the like, to the monitoring device user or patient.
An example of feedback system or subsystem 710 includes, but is not limited to, a feedback engine installed as software and/or firmware on any type at the telemetry system 32. In one embodiment, the feedback system or subsystem 710 is at monitoring device 10 and receives feedback signals from telemetry system.
At block 702, user or patient feedback is detected. Examples of feedback include but are not limited to lifestyle parameters, medical conditions, lifestyle events, exercise parameters, battery 24 life of the monitoring device 10, battery 24 replacement required, lead or sensor 14 function, pending therapy delivery, and the like. The type of feedback and alert conditions detected can vary.
At block 704, a feedback or alert is selected that is associated with a detected feedback or alert condition. Selection of a feedback or alert signal may involve the selection of any of the above listed parameters listed above relative to user or patient, used to control the feedback or alert signal. At block 706 the feedback or alert signal is delivered according to settings selected at block 704.
At block 708, a sensor 14 signal is measured at telemetry system 32 or monitoring device 10, analyzed and compared to a threshold level corresponding to the selected alert level at block 710. An alert threshold level may be predefined or tailored to a given monitoring device user or patient. If the measured sensor 14 response does not correspond to an expected threshold signal level or characteristic pattern of the selected feedback or alert signal, the feedback or alert signal is adjusted at block 712 in a closed-loop feedback method until the sensor signal measured at block 708 falls within a desired range of an expected threshold level, as determined at block 710. Once the desired feedback or alert signal level is reached, the feedback or alert signal stimulation parameters are maintained at the current settings at block 714 to maintain the sensor signal measurement within a desired range of the threshold. Maintaining the feedback or alert signal response within a desired threshold range promotes the reliability of the feedback or alert signal in informing the monitoring device user or patient of a detected parameter described above.
Determining that the sensor signal corresponds to a selected feedback or alert threshold at block 710 may involve detecting a magnitude of the a sensor signal amplitude or frequency, and/or recognizing an intended alert pattern (e.g. short-long burst sequences, strong-weak burst sequences, or the like) based on a morphology of the sensor signal. As such, measuring the sensor signal at block 708 may involve measuring signal magnitude as well as frequency characteristics during the feedback or alert signal delivery.
Additionally or alternatively, frequency characteristics of the sensor signal may be determined to detect sensor 10 signals. The frequency power band of the sensor may be analyzed for correspondence to frequency, amplitude and the like. Additionally, a sensor waveform may be evaluated for correspondence to a frequency or amplitude. A combination of the amplitude and frequency of the sensor signal may also be measured to determine a monitoring device user or patient medical or lifestyle condition.
The feedback or alert signal may be terminated if a predetermined maximum alert duration has expired, as determined at block 716. If a maximum feedback or alert signal duration is not reached, the feedback or alert signal may continue to be held at the current stimulation signal settings at block 714 until the alert expires. Alternatively, the process may return to block 708 to continue monitoring the sensor signal throughout the duration of the alert delivery in order to make further adjustments at block 712 as needed to maintain a desired strength and pattern of the monitoring device user or patient feedback or alert signal. If the feedback or alert signal maximum duration is reached, the signal may be immediately terminated at block 722.
In some embodiments, if a monitoring device user or patient acknowledgement signal is received prior to the maximum signal duration expiring, as determined at decision block 718, the feedback or alert signal is terminated at block 722. A monitoring device user or patient acknowledgment may be in a variety of forms.
In one specific embodiment, if monitoring device user or patient acknowledgement is not received or detected at block 718, the intensity of the feedback or alert signal may be increased at block 720, steadily or in step-wise, pre-determined intervals within a feedback or alert signal maximum duration. It will be appreciated that monitoring device user or patient acknowledgement is not required. The intensity may be increased at block 720 according to a predefined pattern by increasing pulse amplitude (up to some maximum), increasing pulse width, increasing pulse frequency or other adjustment that causes a relatively stronger contraction, i.e., greater recruitment of the muscle being stimulated. Adjusting the intensity of the feedback or alert signal at block 720 may also be performed using sensor signal feedback control by returning to block 708 to compare measured sensor signal characteristics to a next higher feedback or alert signal threshold level. In other words, the sensor signal is compared to a different, increased intensity, threshold than an initial threshold in order to control the feedback or alert signal to elicit a stronger response as compared to the initial feedback or alert signal settings. Thus for a given alert condition, multiple alert intensity levels may be stored in the telemetry system 32 memory along with multiple expected sensor signal responses or thresholds for each intensity level. The sensor signal is used in a closed-loop feedback method to adjust feedback or alert signal control parameters to achieve a feedback or alert signal with the desired intensity at each level.
The feedback or alert signal may be delivered continuously, with continuous or stepwise increasing intensity according to a predefined pattern, until either a maximum alert duration is reached or a monitoring device user or patient acknowledgment is received. In other embodiments, a feedback or alert signal may be delivered intermittently until monitoring device user or patient acknowledgement or expiration of a maximum feedback or alert signal duration, whichever occurs earlier. When delivered intermittently, the feedback or alert signal is delivered at an initial intensity for a predefined alert interval. The feedback or alert signal is held at the current settings at block 714 until the alert interval has expired as determined at block 719. If the alert interval expires, the intensity is increased at block 720 and the feedback or alert signal is resumed for another feedback or alert signal interval at block 721. A pause between differing feedback and alert signal intensities may be applied. As a non-limiting example, the feedback or alert signal may be delivered for a 30 second interval at an initial intensity. This process may continue until a maximum alert duration is reached as determined at block 716, or monitoring device user or patient acknowledgement is received at block 718.
As non-limiting examples, a maximum alert duration may be set at 5 minutes, 10 minutes, 30 minutes, one hour or more and may be set differently for different alert conditions, e.g. according to the seriousness of a particular alert condition. Alert intervals applied during the maximum alert duration may be set differently for different alert conditions and different alert intervals may be applied during a given maximum alert duration. For example, the alert intervals may increase in length as feedback or alert signal intensity is increased.
The same is true relative to the amplitude and duration of the alert signal.
If a maximum alert duration is not reached the alert is terminated at block 722 and optionally repeated at a later time. As described above, a maximum alert duration may correspond to a continuously delivered feedback or alert signal, which may be increased in intensity according to a predefined pattern, or an intermittently delivered feedback or alert signal that includes successive intervals of increasing intensity of the feedback or alert signal with intervening pauses of no feedback or alert signal.
In some embodiments, initial feedback or alert signal settings may be “learned” over time, based on a monitoring device user or patient's response to prior alerting attempts. When a monitoring device user or patient acknowledgement is received at block 718, the feedback or alert signal control parameters are stored at block 723. These alert settings may be used as the initial feedback or alert signal settings the next time the same alert condition is detected (or another condition using the same feedback or alert signal). These stored settings can also be used for further analysis. In one embodiment, the user or patient can provide input relative to the feedback or alert signal. This input can be used to adjust the thresholds for the alerts. In this way, if a previous alert was generated and no monitoring device user or patient acknowledgement occurred until a particular sensor signal amplitude or frequency measurement was reached, the next time the alert is generated, the alert is delivered using a lower setting at which a monitoring device user or patient acknowledgement occurred to improve responsiveness of the monitoring device user or patient to feedback or alert signals.
Adjustment of user or patient parameters at block 712, as the result of an input provided by the user or patient can be provided for maintaining a feedback or alert signal within a targeted threshold level.
The monitoring device 10 and/or the telemetry system 32 can include a feedback loop. User and patient profiles can be stored in database 18, which can include a non-volatile memory. A user or patient can input information 64 about the desired circumstances or parameters relative to a parameter that is measured by a sensor 14. The processor 20 and/or 34 can include a variety of different user and patient profiles relating to information obtained from sensors 14. The processor 20 and/or 34 can customize by either scaling or modifying the user or patient profile based on additional user or patient input information.
Furthermore, feedback or alert signals corresponding to different alert conditions may be distinguished by the monitoring device user or patient by delivering the feedback or alert signals to different body locations. When feedback or alert signals are delivered to different body locations, multiple sensors may be required in the telemetry system 32 system such that a sensor signal responsive to alert stimulation at each body location is available. Depending on the number of body locations and relative distance there between, one or more sensors may be implanted in order to provide at least one sensor in operative relation to each of the targeted alert stimulation sites.
At block 806, a feedback or alert signal pattern for the alert is selected from a person or from telemetry system database 18, and the like, which may be a default pattern for a selected alert condition or customized using any combination signals from sensors 14. Various parameters controlling the alert signal may be programmable.
Optionally, at block 808 a test signal is delivered to the monitoring device user or patient according to a selected sensor signal value. In one embodiment, the sensor signal is measured during the test signal at block 810, which may include measurements of both signal magnitude and frequency characteristics. At block 812, the patient/user may optionally provide input to establish whether the test signal is adequately perceivable and distinct from any other feedback or alert signals that have already been established. User or patient feedback may be received by a user interface included in a monitoring device 10, home monitor, device programmer, or other external device in communication with the telemetry system 32. User or patient feedback may be received by a variety of different ways known in the art when the signal is acceptable or using a signal transmitted by telemetry system 32 or monitoring device 10. A feedback or alert signal may be unacceptable to the monitoring device user or patient.
If the signal is not acceptable to the monitoring device user or patient, or not adequately measured by a sensor 14 to facilitate closed-loop feedback of the signal, as determined at block 814, one or more feedback or alert signal control parameters is adjusted at block 816, and the process at blocks 808 through 814 repeats until an acceptable feedback or alert signal is established. The feedback or alert signal settings and the sensor signal characteristic(s) associated with the acceptable feedback or alert signal are stored at block 818 to establish a threshold range of the magnitude and/or frequency characteristics of the sensor signal for the given feedback or alert signal.
If additional alert conditions can be detected by the telemetry system 32, as determined at block 820, a unique feedback or alert signal pattern can be selected for the next alert condition by returning to block 804 and repeating the process shown in blocks 804 through 818. Each alert condition may be assigned a unique monitoring device user or patient feedback or alert signal that is established by storing expected sensor signal characteristics with corresponding feedback or alert signal parameters. The monitoring device user or patient can provide feedback such that each feedback or alert signal is easily perceived, recognized and distinguished from other feedback or alert signals.
For each acceptable feedback or alert signal, a sensor threshold level is established, which may include both a magnitude component and a frequency component. The stored sensor signal thresholds allow the feedback or alert signal to be adjusted as needed during an actual monitoring device user or patient alert to most closely match the magnitude and/or frequency characteristics of the established feedback or alert signal. The monitoring device user or patient can be “trained” to recognize different feedback or alert signal patterns, intensities (strength or duration of the muscle response), and/or locations and their correspondence to different alert conditions.
Once all sensor-based threshold characteristics have been stored for all alert conditions, the process is terminated at block 822. The stored sensor signal data can then be used in a closed-loop feedback method for controlling feedback or alert signal stimulation parameters during normal operation of the telemetry system 32 as described in conjunction with

The database includes base standards for at least one of user, activities, behaviors, habit information and health information that is indicative of a healthy lifestyle of activities, behaviors, habit information, exercise programs and health condition. The user information received from the monitoring device 10 is analyzed relative to the base standards in the database. In one embodiment, the base standards in operation are updatable. The update information includes updated base standards.
