[0003] Individual sensors with or without wireless transceivers have been created and used for collecting and transmitting physiological data. Systems of sensors have been at various stages of development, commonly referred to as Body Area Networks (BANs). If wireless communication is employed the system is called Wireless Body Area Networks (WBANs), utilizing a storage device for aggregating the data for future access and processing, or are dependent on wireless transceivers, smart phones and similar mobile devices for collecting and transmitting the data to a healthcare provider. While such systems work for their intended purposes, they are cumbersome and difficult to operate, both from the perspective of weight and size of the equipment. In addition, they require many wires for interconnecting the various components, further rendering the equipment difficult to operate and use. [0004] Given the foregoing, there is a need for an improved wireless device for the collection, storage, transmission and presentation of physiological data. There is also a need for an improved lightweight, wireless device that allows for ease of use and desirability.

[0030] In yet another aspect of the present invention, the computer program product of the present invention, use control logic to sense physical and orientation activity using a mechanical device, which may be an accelerometer, an inclinometer or the like. Additionally, the computer program product uses additional control logic to process data regarding the physical and orientation activity and transmitting the generated data. [0031] Aspects of the present invention will now be described in more detail herein in terms of the above exemplary context and the accompanying figures. This description is for convenience only and is not intended to limit the application of aspects of the present invention. In fact, after reading the following description, it will be apparent to those skilled in the relevant art(s) how to implement aspects of the following invention in alternative ways. [0032] The terms "person," "patient," "subject," "user," "subscriber," "client,"

"wearer," "being," and/or the plural form of these terms are sometimes used interchangeably herein to refer to those person(s) or other living being(s) from whom physiological data are being collected (or, in some cases, the safety and medical personnel and professionals entrusted with their well being), and thus would benefit from the system, method, and computer program products that aspects of the present invention provide for facilitating the receipt, collection, storage, transmission and presentation of physiological data of persons or other living beings.

[0033] Referring to FIG. 1, an electronic block diagram of body-wearable (i.e., body patch) device 100 according to an aspect of the present invention is shown. In this aspect, device 100 comprises one or more electrodes 402a, 402b...402n (shown in FIG. 4), one or more one or more sensors 102a, 102b...102n, an accelerometer or inclinometer or similar activity/body positioning mechanical device 104, a signal conditioning unit 106, an on-board computer 108 (with memory), a clock 110, a power supply 112, a transceiver 114 and antenna 116. Various aspects of the present invention may include more or fewer components than those shown in FIG. 1. [0034] Sensors 102a, 102b...l02n are used to collect physiological and activity data.

Physiological data collected by sensors 102a, 102b...102n may include body surface temperature, ambient temperature, ambient humidity, heart rate, electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG), orientation, galvanic skin resistance, photoplethysmograph, location and activity. Sensors 102a, 102b...l02n are electronic devices which receive signal impulses from electrodes or other sensing surfaces (i.e., electrodes 402a, 402b...402n as shown in FIG. 4). Such electrodes or sensing surfaces may or may not touch on the surface of the skin of a monitored person. These electrodes transmit their electrical signals to sensors 102a, 102b...l02n, which in turn interpret the signals and forward the data to on-board computer 108.

[0035] Accelerometer, inclinometer or similar mechanical device 104 is used to sense the orientation and physical activity of the person wearing patch 100. Accelerometer 104 can provide data to determine the state of the person - for example whether the person is moving fast or slow, being immobile or resting. Accelerometer 104 can also be used to provide information on the person's orientation for example sitting, lying down, or a sudden change of body position that has occurred (e.g. sudden fall), etc. Accelerometer data is first sent to on-board computer 108 where the data is then analyzed using computer programs (algorithms) resident on on-board computer 108. The computer programs are configured to determine the user's condition (e.g., whether the user has fallen).

[0036] • Signal conditioning unit 106 is used to modify the signals and/or data received from sensors 102a, 102b...102n. Such modification, in one aspect of the present invention, may include amplification or filtering of the signals as needed in order for the signal or data to be processed. In this aspect of the present invention, signal amplifiers may be used for this purpose.

[0037] Clock 110 has the primary purpose of synchronizing various components found on patch 100. It is also used for synchronisation of external components, because there is communication with other devices, through transceiver 114. Device 100 and communications synchronisation is managed through on-board computer 108. Clock 110 may also be integrated as an integral part of on-board computer 108 to simplify the implementation.

[0038] Transceiver 114 and associated antenna 116 are the communication interface for patch 100 to communicate with external devices external devices within a WBAN as described in more detail in U.S. Provisional Application No. 60/897,243 titled "Method and System for Physiological Data Readings, Transmission, and Presentation," filed on January 25, 2007. Antenna 116 is used for transmitting and receiving signals while transceiver 114 defines the communication protocols and frequencies supported for communication. Any number of protocols may be used, the majority of which specify an operating frequency range. Other protocols may operate on a single frequency. Transmission protocols may include ZigBee (802.15.4), Cellular (CDMA, GSM and others), Wireless (802.11 a/b/g/n), Wi-Fi (802.11 p), ANT, Bluetooth (802.15.1) or custom wireless protocols working in any available frequency or frequencies.

[0039] Power supply 112 may consist of one or multiple batteries, which may or may not be replaceable depending on the configuration. Power supply 112 provides the necessary electrical power to the electronic components, so they can operate properly and perform their designed tasks. Because the availability of sufficient power is necessary for the proper operation of the electronic components, on-board computer 108 monitors the power levels and generates a notification message when it detects power levels below a certain threshold. This power threshold is defined by the suite of electronic components on the patch and their collective power requirements for proper operation. The notification message is transmitted to an external device, to indicate and warn that the power level on the patch is becoming insufficient for sustaining ongoing operations.

[0040] In another aspect of the present invention, device 100 may be powered by using external RF transmission and an inductive coil. Furthermore, device 100 can be powered by harvesting energy from the body's motion, differential temperature gradient, applied pressure (piezoelectric sensors), using collar cells, etc.

[0041] On-board computer 108 is the controlling unit for all electronic components within device 100. On-board computer 108 is also the processing unit for incoming and outgoing signals and data. On-board computer 108 also manages all communications, through transceiver 114, with external devices. Such other devices, in one aspect of the present invention, may be a body-wearable gateway collecting data from the patch 100 and/or other physiological data different than the data from the patch, as described in more detail in co-pending U.S. Provisional Application No. 61/006,095, titled "Gateway for Discrete and Continuous Monitoring of Ambient Data with Emergency Functions," filed on December 19, 2007 and U.S. Provisional Application No. 61/006,097, titled "Gateway for Discrete and Continuous Monitoring of Physiological Data," filed on December 19, 2007; which are incorporated by reference herein in their entirety. In effect, on-board computer 108 is a computer system similar to the block diagram in FIG. 2.

[0042] Referring now to FIG. 2, a computer system 108 depicting various computer system components for use with an exemplary implementation of a data collection, communications and analysis device, in accordance with an aspect of the present invention is shown.

[0043] Various software aspects are described in terms of this exemplary computer system. After reading this description, it will become apparent to a person skilled in the relevant art(s) how to implement the invention using other computer systems and/or architectures.

[0044] The computer system 108 includes one or more processors, such as processor

204. Processor 204 is connected to a communications infrastructure 202 (e.g., a communications bus, cross-over bar or network). Computer system 108 can include a display interface 208 that forwards graphics, text and other data from the communication infrastructure 202 (or from a frame buffer not shown) for display on display unit 210. [0045] Computer system 108 also includes a main memory 206, preferably random access memory (RAM), and may also include a secondary memory 212. The secondary memory 212 may include, for example, and/or a removable storage drive 216, representing a flash memory card, a magnetic tape drive, an optical disk drive, etc. The removable storage drive 216 reads from and/or writes to a removable storage unit 218 in a well known manner. Removable storage unit 218 represents a flash memory card, magnetic tape, optical disk, etc. which is read by and written to by removable storage drive 216. As will be appreciated, the removable storage unit 218 includes a computer usable storage medium having stored therein computer software and/or data.

[0046] In alternative aspects, secondary memory 212 may include other similar devices for allowing computer programs or other instructions to be loaded into computer system 108. Such devices may include, for example, a secondary removable storage unit and an interface. Examples of such may include a program cartridge and cartridge interface (such as that found in video game devices), a removable memory chip (such as flash memory, an erasable programmable read only memory (EPROM), or programmable read only memory (PROM)) and associated socket, and other secondary removable storage units and interfaces, which allow software and data to be transferred from the secondary removable storage unit to computer system 108.

[0047] Computer system 108 may also include a communications interface 224.

Communications interface 224 allows software and data to be transferred between computer system 108 and external devices. Examples of communications interface 224 may include a modem, a serial interface, such as Universal Serial Bus (USB) or RS232, a network interface (such as an Ethernet card), a communications port, etc. Software and data transferred via communications interface 224 are in the form of signals 226 which may be electronic, electromagnetic, optical or other signals capable of being received by communications interface 224. These signals 226 are provided to communications interface 224 via a communications path (e.g., channel) 228. This channel 228 carries signals 226 and may be implemented using wire or cable, fiber optics, a telephone line, a cellular link, an radio frequency (RF) link and other communications channels.

[0048] In this document, the terms "computer program medium" and "computer usable medium" are used to generally refer to media such as removable storage drive 216, a hard disk installed in hard disk drive 214, and signals 226. These computer program products provide software to computer system 108. The invention is directed to such computer program products. [0049] Computer programs (also referred to as computer control logic) are stored in main memory 206 and/or secondary memory 212. Computer programs may also be received via communications interface 224. Such computer programs, when executed, enable the computer system 108 to perform the features of the present invention, as discussed herein. In particular, the computer programs, when executed, enable the processor 204 to perform the features of the present invention. Accordingly, such computer programs represent controllers of the computer system 108.

[0050] In an aspect where the invention is implemented using software, the software may be stored in a computer program product and loaded into computer system 108 using removable storage drive 216, hard drive 214 or communications interface 224. The control logic (software), when executed by the processor 204, causes the processor 204 to perform the functions of the invention as described herein.

[0051] Aspects of the present invention may also be implemented using, for example, a microcontroller. A microcontroller may include a microprocessor on a single integrated circuit configured to operate as a single-chip embedded system. The microcontroller may include a CPU, RAM as working memory, program memory (e.g. flash memory, ROM, or PROM), direct memory access (DMA), timers, I/O ports, other serial communications interfaces, EEPROM or flash memory for permanent data storages, peripheral devices (such as timers, event counters, etc.), a clock generator, analog-to-digital converters, digital-to- analog converters, comparators, and in-circuit programming and debugging support. [0052] In another aspect, the invention is implemented primarily in hardware using, for example, hardware components such as application specific integrated circuits (ASICs). Implementation of the hardware state machine so as to perform the functions described herein will be apparent to persons skilled in the relevant art(s).

[0053] In yet another aspect, the present invention is implemented using a combination of both hardware and software.

[0054] Referring now to FIG. 3, a flowchart depicting exemplary operation and data flow 300 of device 100 according to an aspect of the present invention is shown. In this aspect, physiological and/or ambient data previously received by one of a combination of sensors 102a, 102b...l02n, contained within device 100 is then collected and stored in step 302 into the internal storage of on-board computer 108 to be processed for on-patch analysis. In step 304, the data is processed by on-board computer 108 for on-device analysis. Next, in step 304, processor 108 determines whether it is time to initiate a scheduled transmission of the data to a pre-defined external device, individual, or location. If it is not yet time for the transmission, device 100 waits in step 308 until it is time to transmit. If in step 306 on-board computer 108 determines that it is time to transmit, the transmission preparation process begins. In preparing the data for transmission, all the data from the internal storage of onboard computer 108 (including data from external devices, accelerometer 104 and signal conditioning unit 106) and readings from sensors 102a, 102b...l02n, are aggregated in step 310.

[0055] In step 312, the data is then encrypted and packaged for transmission in step

314. The data is encrypted to ensure its security during transmission. In packaging the data, identifying information such as source, destination, transmission type and other pertinent information are included in step 314 in preparation for transmission. The data is then packaged into a message, according to the transmission protocol being employed. Any number of protocols may be used, the majority of which specify an operating frequency range and signal modulation. Other protocols may operate on a single frequency. In alternate aspects, transmission protocols may include ZigBee (802.15.4), Cellular (CDMA, TDMA, GSM and others), Wireless (802.11 a/b/g/n), Wi-Fi (802.11 p), ANT, Bluetooth (802.15.1) or custom wireless protocols working in any available frequency or frequencies. In step 316, on-board computer 108 activates transceiver 114.

[0056] After transceiver 114 has been activated and a network connection is established in step 316, a burst transmission of data from device 100 to an external device occurs in step 318. Such external device may be a body-wearable gateway collecting other physiological data different than, and in addition to, patch 100 as described in more detail in co-pending U.S. Provisional Application No. 61/006,095, titled "Gateway for Discrete and Continuous Monitoring of Ambient Data with Emergency Functions," filed on December 19, 2007 and U.S. Provisional Application No. 61/006,097, titled "Gateway for Discrete and Continuous Monitoring of Physiological Data," filed on December 19, 2007; which are incorporated by reference herein in their entirety. Transceiver 114 is then deactivated until the next transmission event (e.g., until data flow 300 is repeated). At the external device, the transmitted data undergoes further analysis, processing and preparation for reporting. [0057] Referring now to FIG. 4, a schematic diagram of device 100 according to an aspect of the present invention is shown. The electronic components of device or patch 100 (as shown in FIG. 2) are packaged in a water tight container to prevent short circuits from moisture and are connected to a printed circuit board (PCB) 404, for example in one embodiment, by soldering, which may be constructed of flexible material, so not to restrict freedom of movement. PCB 404 is attached to a bandage-type (fabric, which may be synthetic) material 406 (thus the reference to device 100 as a "patch") with only electrodes 402a, 402b...402n protruding through the bandage-type material in order to make contact with the monitored person's skin or body. One side of the patch 100 contains adhesive 408 which secures the patch onto the monitored person's skin or body.

[0058] Electrodes 402a, 402b...402n make contact with the skin and adhesive 408 holds them in place, ensuring a constant and secure contact which is necessary to provide accurate and continuous collection of physiological data.

[0059] Power supply 112 is located on the PCB 404 and may or may not be replaceable. In the case of a non-replaceable power supply, the whole patch becomes disposable, because no data can be collected and transmitted when there is insufficient power. In the case of a replaceable power supply, the battery compartment is sealed with a traditional water resistant twist-lock cap, which when opened allows the batteries to be replaced. FIG. 5 shows a representative twist-lock battery cap and battery 112, but 112 may also be a thin film battery.

[0060] Referring now to FIG. 6, a schematic diagram depicting device 100 according to another exemplary aspect of the present invention is shown. Specifically, in FIG. 6, a different configuration of the patch assembly allowing for more flexibility and longevity is shown. The patch or device 100 could be constructed of two separate components, one that can be non-disposable and one that is disposable. Non-disposable piece 602 contains all the electronics, excluding electrodes 402a, 402b ... 402n. The construction is the same as with the single piece patch, except there are connectors 606a, 606b ... 606n used to connect non- disposable piece 602 to disposable piece 604. Disposable piece 604 contains electrodes 402a, 402b...402n. This configuration provides two alternatives for power supply 112. In one aspect of the present invention, power supply 112 could be placed in non-disposable piece 602, mounted on PCB 404, along with the other electronic components. In this configuration, power supply 112 may be either replaceable or not. Another aspect of the present invention places power supply 112 in disposable piece 604, along with electrodes 402a, 402b...402n. In this configuration power supply 112 does not need to be replaceable, because it is found within the disposable portion of device 100.

[0061] Aspects of the present invention include an integrated system for obtaining a person's physiological data (vital signs) and other relevant data regarding the person or person's surrounding atmosphere, through non-invasive methods, via a biosensor device and securely transmitting the information and transforming it into an easily understood display.

[0062] Aspects of the present invention are directed to a physiological and activity data aggregation, transmission and presentation system, for the purpose of monitoring a person's vital signs by the person, the person's family members, care takers and healthcare providers, through non-invasive means. This aspect includes at least one biosensor, a gateway device, short and long range transceivers, proprietary software for data aggregation and transmission from multiple sensors, a data centre environment with multiple computers and custom software for data storage, retrieval, manipulation, analysis, display and transmission to an end-user viewing device via the Internet. This system is completely wireless and presents the data to the end users on both a periodic and optionally, on a realtime basis based on a triggering event or on request. The system components placed on a person's body are small and lightweight so that they do not interfere with normal daily activities. Finally, the gateway device offers alert features including simple two-way voice communication.

[0063] The system obtains physiological and other relevant data from at least one sensor, processes the data, encrypts the data, and then transmits the data to the gateway device. That gateway aggregates the physiological data from all the sensor sources, processes the data, and forwards the data to a data collection centre. Additional processing and analysis of the data may occur at the data collection centre.

[0064] In an aspect, the sensor may include an adhesive patch attached to the body of a person, integrating several miniaturized physiological sensors. This patch may include a microprocessor, a short-range wireless transceiver and a power supply miniaturized onto a single board. The sensors obtain vital sign physiological data, which are processed, encrypted and aggregated by the microprocessor for transmission by the transceiver to the gateway, at set intervals. The gateway then transmits the data to the data collection center.

[0065] In one embodiment, the patch may include a feature to measure galvanic skin resistance (GSR).

[0066] In another embodiment, the patch has a feature for determining if the patch is loose or has been removed. In one exemplary embodiment, the amount of resistance between at least two electrodes may be measured. In one embodiment, the at least two electrodes may be the electrodes in an ECG sensor. A person's skin is expected to have a resistance within a certain range. Therefore, removal of the patch may be determined when the resistance between the at least two electrodes rises above that range. In another embodiment, a determination may be made that a patch has become loose by recognizing that large variations in a signal, coming from at least one sensor, have occurred. [0067] In certain embodiments, the identification of a loose or removed patch may trigger an alarm that alerts the monitored person that the patch has become loose or removed. This alarm may be a sound, light, vibration, etc. In addition, a message may be sent to the subscriber and/or the call or data center to notify that a patch has become loose or removed from the monitored person.

[0068] In one embodiment, at least one biosensor, for example on the patch, may process the data to determine whether an "event" has occurred. An event may include at least one of the monitored physiological or other characteristics falling outside a predetermined range, or a trend of parameter change specified by the user (e.g. evident trend of heart rate decrease or abnormal fall, predefined changes in heart rhythm, etc.).. The predetermined range may be set at will through a web interface. The predetermined range information will be sent to the gateway and patch, stored, and used in analyzing sensor data for events.

[0069] When the biosensor determines that an event has occurred, the patch or the gateway transmits data in an event mode for a predetermined period of time. Event mode transmission involves a transmission of physiological or other data in a different form than the previously processed, packaged, and periodically transmitted data. For example, in one embodiment, once an event has been identified, the at least one sensor may transmit unprocessed data on a near real time basis in addition to the results of processing. This at least one sensor may be the sensor that recorded the event data that falls outside the predetermined range.

[0070] For example, at least one biosensor may measure the pulse rate of the monitored person. A family member, care giver, or physician may have set a predetermined acceptable range for the heart rate of the monitored person. If the biosensor determines that the heart rate has fallen below the acceptable range, the biosensor will begin to transmit data to the gateway on a different basis. For example, the biosensor may transmit the ECG signal or the sequence of RR intervals on a near real time basis for a predetermined period of time. Although in this example the biosensor transmits real time heart rate data, the gateway may transmit any type of additional data in this event mode, such as body position and activity signals, as well as previous history of the selected parameter.

[0071] Other possible triggers may include the detection of a fall, cardiac changes,

ECG morphology changes (e.g. QT segment, ST segment deviation, J-point value, etc.), wandering outside a pre-determined distance from a defined base location, etc.

[0072] In one embodiment, based on the event mode transmission, a number of actions may occur. An emergency call may be placed to the gateway to attempt to contact the monitored person. This call may provide more information on the status of that person or provide assistance to the person. A call may be directed to emergency services to direct an emergency response to the location of the monitored person. A call may be directed to a selected contact such as a family member, a care giver, or a physician. An alarm may be sounded at the gateway device. An emergency message may be sent via e-mail, pre-recorded voice mail, text message, or any other desired method, to a family member, care giver, or physician.

[0073] By determining an event, and by sending data in a special event mode transmission, the biosensor may provide for automatic alerts or emergency responses in potentially life threatening situations.

[0074] After the event mode transmission, the biosensor may return to normal acquisition and transmission of data to the gateway until another event mode is determined. [0075] Although the gateway and system may function together with a plurality of additional sensors, the gateway does not require an additional sensor in order to function accurately. For example, the gateway may receive short range transmissions of data from a plurality of sensors placed on the body of the monitored person. The gateway may be capable of accumulating, processing, and packaging this information, together with any information gathered at the gateway device, and transmitting the packaged data.

[0076] However, in accordance with one aspect, the gateway device and system are also capable of functioning properly without data transmissions from additional sensors. In an exemplary embodiment, a subscriber to the system, whether the monitored person, the person's family member, care giver, or physician, may select a "gateway only" option, where the monitored person does not wear any additional sensors. In another aspect, although the subscriber to the service may have selected an option with at least one additional sensor, the sensor may function improperly or cease to function for any number of reasons. When this occurs, the gateway is configured to continue to report the malfunction and continue to properly collect and transmit data without the sensor.

[0077] The system is also capable of collecting and analyzing data from various types of biosensors. For example, the system is capable of functioning with biosensors from a plurality of manufacturers. The biosensors may include a common interface to the gateway or to the data collection center. This interface may ensure that data transmitted to the data collection center is transmitted in a particular format. Each of the manufacturers may offer more than one type of biosensor, with each model offering a different combination of features. The system is capable of identifying the manufacturer and model of a biosensor from the data transmitted to the remote collection center. This feature provides the ability to make an analysis of the performance of different models and manufacturers of biosensors.

[0078] In order to protect the privacy of the monitored person, data transmissions are encrypted before being transmitted. In one aspect, data is encrypted at the gateway device before being transmitted to the data collection center. In another aspect, data is encrypted at the sensor or patch before it is transmitted to the gateway. In a further aspect, data is encrypted both at the sensor and the patch before transmission to the gateway and at the gateway before transmission to the data collection center.

[0079] In another aspect, the biosensor or patch, or both, include a buffering feature that stores collected data when it is determined that transmissions are not reaching the gateway correctly. In one example, the biosensor or patch may receive an acknowledgement of transmission from the gateway when a transmission is received. If the acknowledgement is not received, the biosensor or patch begins to store data transmissions in buffer memory. When an acknowledgement is received, the data transmissions in the buffer memory are transmitted. The biosensor or patch stores data transmissions in the buffer memory until the memory is full. Once the memory is full, the buffer stores the most recent data collected.

[0080] In another aspect, the gateway includes a buffering feature that stores collected data when it is determined that transmissions are not reaching the data collection center correctly. In one example, the gateway may receive an acknowledgement of transmission from the data collection center when a transmission is received. If the acknowledgement is not received, the gateway begins to store data transmissions in buffer memory. When an acknowledgement is received, any intervening data transmissions stored in the buffer memory are transmitted and then deleted along with the acknowledged. The gateway stores data transmissions in the buffer memory until the memory is full. Once the memory is full, the buffer stores the most recent data collected.

[0081] In one aspect, both the biosensor and the gateway include a buffering feature.

In another aspect, a warning is generated at the biosensor, the patch, or the gateway, to alert the monitored person that there is an error with data transmission.

[0082] In another aspect, a message may be generated to the subscriber and/or the call centre if transmission is interrupted between the sensor and the gateway or between the gateway and the data collection center for a predetermined period of time. The predetermined period of time may be a default, and may be an option that can be set by the subscriber. In one embodiment, a default period of time may be between 3 and 5 minutes.

[0083] While various aspects of the present invention have been described above, it should be understood that they have been presented by way of example, and not limitation. It will be apparent to persons skilled in the relevant art(s) that various changes in form and detail can be made therein without departing from the spirit and scope of aspects of the present invention. Thus, aspects of the present invention should not be limited by any of the above described exemplary aspects, but should be defined only in accordance with the following claims and their equivalents.

[0084] In addition, it should be understood that the figures in the attachments, which highlight the structure, methodology, functionality and advantages of aspects of the present invention, are presented for example purposes only. Aspects of the present invention are sufficiently flexible and configurable, such that it may be implemented in ways other than that shown in the accompanying figures.
