Provisional Patent for an Emergency Call System

Authors: Peri Avitan, Robert J. Benetti, Bryan T. Benetti, and Robert A. Benetti

OVERVIEW

Health Care Signaling Equipment (including Medical Alerts) Personal Emergency Response Equipment, Emergency Call Systems, and Hospital Signaling and Nurse Call Equipment comprise a wide range of individual components and systems that are used to electronically signal to another individual or caregiver, multiple individuals or caregivers, and/or a Central Station that they are in need of personal assistance or medical assistance for both routine and acute emergency situations in a wide range of environments, including:

- Personal residences and their surrounding property.
- During out of home excursions and travel.
- During temporary or extended stays in assisted living and independent living facilities.
- In hospitals and other acute care facilities.
- Etc.

All of the above types of systems will be referred to herein as Emergency Call Systems (ECS).

An ECS is typically accompanied by a portable call initiation station (pendant) which may be handheld, body worn, or attached to a person's clothing. These pendants provide assistance request or emergency request signaling to the ECS and/or directly to a Central Station via wireless technology (RF, Wi-Fi, cellular, etc.). All of the various types of pendants will be referred to herein as ECS Pendants.

The various types of ECS and ECS Pendants are certified by domestic safety standards that are published by Underwriters Laboratory (UL) and similar international standards for various usages and operating environments:

- a. UL 1637 Home Health Care Signaling Equipment.
- b. UL 1698 Personal Emergency Response Equipment—(proposed standard)
- c. UL 2560 Emergency Call Systems for Assisted Living and Independent Living Facilities.
- d. UL 1069 Hospital Signaling and Nurse Call Equipment.

These standards have different safety and operational performance requirements for the various usage scenarios and operating environments. Please refer to FIG. 10 for the following discussion:

The dashed lines around the environments covered under UL 1637 and UL 1698 (proposed standard) represents that these environments are currently using ECS and/or ECS Pendants that communicate ECS signaling to another individual or individuals, caregivers, or a Central Station via the public switched telephone network (PSTN) or cellular network.

UL. 1637 Home Health Care Signaling Equipment

[The following was excerpted from UL 1637]

1 Scope

1.1 These requirements cover the individual units that comprise a home health care system intended for use in ordinary indoor residential locations.

- [Note that this requirement specifically states “for use in ordinary indoor residential locations” with no allowance for outdoor use, or the multitude of complex environments that will be addressed in the proposed UL 1698 standard]

1.2 These requirements also cover a complete home health care system in which a signal initiating device (both routine monitoring and medical emergency signals) may be connected directly or indirectly to receiving equipment at a residence or to continuously monitored receiving equipment at a central supervising station. The system is arranged so that a predetermined change in the status of the signal initiating circuits or devices automatically causes transmission of a signal over a communication channel to receiving equipment at a residence, to a central supervising station, or to a private telephone number.

- [Note that this requirement states: “transmission of a signal over a communication channel . . . ” with no definitive safety or performance requirements in the standard for communication over cellular networks which will be addressed in the proposed UL 1698 standard]

1.3 The components of the home health care system may include signal initiating devices, control units, transmitters, and digital communicators, all located at the residence, and the receiving, processing, and displaying equipment located at the central supervising station.

- [Note that this requirement states: “may include signal initiating devices, control units, transmitters, and digital communicators, all located at the residence . . . ” with no definitive safety or performance requirements in the standard for devices used outside of the residence and communication over cellular networks which will be addressed in the proposed UL1698 standard]

UL 1698 Personal Emergency Response Equipment (Proposed)

[The following was excerpted from the proposed Scope for UL 1698]

Scope

Covers application, construction, and performance of equipment utilized in personal emergency response systems. The purpose of this standard is to define the means of signal initiation, transmission, notification and annunciation; level of performance; and the reliability of various types of personal emergency response systems. The standard also defines the features associated with these systems.

- [This is a proposed UL standard that is currently under development and not yet published as of Mar. 29, 2016.
- It is not specifically stated in the above Scope, however, the Scope will include the wide range of environments illustrated in FIG. 10, and include cellular communication and advanced locating technologies that includes GPS for: single and multilevel (aka multi-floor) personal residences, apartments, hotels, cities with high rise building, shopping malls, multistory buildings, multilevel and underground roadways and parking garages, rural areas, parks, recreation areas, traveling in vehicles, etc.]

UL 2560 Emergency Call Systems for Assisted Living and Independent Living Facilities

- [Referring to FIG. 10 the solid line around the environments covered under UL 2560 represents that these environments are currently not using ECS Pendants for ECS signaling, two-way voice communication, and alarm clearing via PSTN, Internet, cellular network, or other method of communication to caregivers or a Central Station that are remotely located.]

[The following was excerpted from UL 2560]

1 Scope

1.1 These requirements cover the individual unit employed to form assisted and independent living emergency call systems (ECS) intended to provide audible and visual signaling between residents and assisted and independent living facility staff. Some examples include call initiation stations, call notification stations, and power supplies.

- [Note that under the following section 40.2.1 b of UL 2560 (below) it states, “A required battery trouble call shall be transmitted to the receiver for a minimum of 7 days before the battery capacity of the transmitter has depleted to a level insufficient to maintain proper non-call operation of the transmitter.” There is also a battery life performance test under section 41.1.1 (see below) to ensure that the ECS Pedant meets this requirement. As such, by using a single low power RF transceiver and battery as in the current competitive product offerings it is not feasible to include two-way audio and/or videoconferencing capability into an ECS Pendant. The LiveCare™ ECS Pendant uses a novel dual transceiver/dual battery design that provides UL 2560 compliant ECS signaling and concurrent two-way audio and/or HIPAA compliant videoconferencing in the same ECS Pendant (see LiveCare™ ECS and LiveCare™ ECS Pendant, below)]

40.2.1 A primary battery is not prohibited from being used as the sole source of power for a low-power radio transmitter when all of the following conditions are met:

- a) The capacity of the primary battery shall be monitored for integrity. The battery shall be monitored while loaded by:
  - 1) Transmission of the transmitter or
  - 2) A load equivalent to the load imposed by transmission.
- b) A required battery trouble call shall be transmitted to the receiver for a minimum of 7 days before the battery capacity of the transmitter has depleted to a level insufficient to maintain proper non-call operation of the transmitter. It is acceptable for the battery trouble call at the call notification station to be initially delayed up to 24 hours.
- c) The battery of a transmitter shall be capable of operating the transmitter in its normal supervisory mode and placing a single emergency call per day, each call remaining for 5 minutes before it is reset, for a published manufacturer specified length of time before the battery depletion threshold specified in (b) is reached.

41 Primary Batteries Test

41.1 Life Test

41.1.1 When a primary battery is used as the main source of power for a low power radio transmitter, it shall provide power to the unit under intended ambient conditions for the manufacturers specified battery life using the normal signaling performance as described in 40.2.1(c) and then operate the transmitter for a minimum of 7 days of trouble signal. Data on battery life, including discharge curves, shall be provided for the investigation to evaluate battery performance characteristics.

UL 1069 Hospital Signaling and Nurse Call Equipment

- [Referring to FIG. 10 the solid line around the environments covered under UL 1069 represents that these environments are currently not using ECS Pendants for ECS signaling, two-way voice communication, and alarm clearing via the PSTN, internet, cellular network, or other method of communication to caregivers or a Central Station that are remotely located.]

1 Scope

1.1 These requirements cover the individual units employed to form a hospital nurse call system (NCS) intended to provide audible and visual communication between patients and hospital personnel. They also cover miscellaneous signaling equipment employed in hospitals. Some examples include bedside tables, annunciators, power supplies for nurse call systems, and gas monitoring units.

- [Note that under the following section 49.2.1 b of UL 1069 (below) it states, “A required battery trouble call shall be transmitted to the receiver for a minimum of 7 days before the battery capacity of the transmitter has depleted to a level insufficient to maintain proper non-call operation of the transmitter.” There is also a battery life performance test under section 50.1.1 (see below) to ensure that the ECS Pedant meets this requirement. As such, by using a single low power RF transceiver and battery as in the current competitive product offerings it is not feasible to include two-way audio and/or videoconferencing capability into an ECS Pendant. The LiveCare™ ECS Pendant uses a novel dual transceiver/dual battery design that provides UL 2560 compliant ECS signaling and concurrent two-way audio and HIPAA compliant videoconferencing in the same ECS Pendant (see LiveCare™ ECS and LiveCare™ ECS Pendant, below)]

49.2 Primary Batteries

49.2.1 A primary battery is not prohibited from being used as the sole source of power for a low-power radio transmitter when all of the following conditions are met:

- a) The capacity of the primary battery shall be monitored for integrity. The battery shall be monitored while loaded by:
  - 1) Transmission of the transmitter or
  - 2) A load equivalent to the load imposed by transmission.
- b) A required battery trouble call shall be transmitted to the receiver for a minimum of 7 days before the battery capacity of the transmitter has depleted to a level insufficient to maintain proper non-call operation of the transmitter. It is acceptable for the battery trouble call at the Primary Nurse Control Station to be initially delayed up to 4 hours. The battery trouble annunciation shall be retransmitted at intervals not exceeding four hours until the battery is replaced.

The novel design also includes non-HIPAA compliant and/or HIPAA

compliant multiparty videoconferencing for:

Billable remote patient monitoring, performing audio and visual medical

examinations, and medical consultations.

Videoconferencing with remote family and friends as allowed in the

particular environments.

Multiparty two-way videoconferencing is not required in the standards, but

provided in some embodiments. Multiparty two-way videoconferencing

allows remote caregivers, attending physicians, and medical specialists to

examine and consult with private individuals, assisted living residents, and

hospital or acute care patients without having to travel to the specific

location. Due to recently enacted legislation, this type of remote telehealth

service is also becoming a billable service for the physicians. As with

multiparty two-way audio conferencing, multiparty videoconferencing

improves customer satisfaction by having quick access to their physician or

specialist, and improves staff efficiency by reducing travel within and to

facilities.

An added benefit of providing audio and video conferencing is the ability to

visit with friends and family which can significantly improve user well-

being and satisfaction

Novel Designs:

Concurrent ECS signaling and multiparty two-way audio and/or video

conferencing requires a novel design to ensure adequate battery performance

that is required in the standards. ECS signaling requires long-lasting batteries

that can provide continued signaling up to 7 days after a low battery

condition has been detected. However, as every cell phone user has

experienced, several hours of audio communication or videoconferencing

can rapidly deplete batteries in less than 24 hours. As such, LiveCare

engineering has developed a novel dual radio transceiver architecture with

dual batteries to provide low power ECS signaling that is powered from a

primary or secondary battery, and a separate wireless transceiver and

associated subsystems that are powered by a higher capacity rechargeable

battery for audio and video conferencing that can be recharged daily while

the patient sleeps. The larger capacity rechargeable battery also provides the

ability to provide a wide range of other features not normally available in a

low power ECS signaling pendant such as a backlit touchscreen, “Walking

Light ™”, “Reading Light ™”, high power audio amplifier, etc. An ECS

signaling subsystem secondary battery is recharged any time the larger

capacity battery is being recharged to significantly improve the effective

battery life of the ECS signaling battery. The ECS signaling subsystem can

be powered by rechargeable super capacitor, ultra-capacitor, or other energy

storage system as the associated regulatory standard permits.

LiveCare engineering has also developed a novel architecture with ECS

signaling and multiparty two-way audio and video conferencing that

operates from a single high capacity rechargeable battery. Advanced battery

fuel gauge monitoring with associated battery aging analysis software allows

concurrent ECS signaling and multiparty two-way audio and video

conferencing (and other high power features) wherein two-way

videoconferencing and other non-critical function are suspended at low

battery reserve levels to allow continued signaling with continued two-way

audio conferencing. At lower battery discharge levels, two-way audio

conferencing and other noncritical functions are suspended to allow

continued signaling up to 7 days or as stipulated by the respective standard

after a lower battery condition has been detected.

Automatic user, caregiver, and/or Central Station notifications at the various

battery discharge states.

Personal Medical Device
Background and Summary

The present invention relates generally to portable devices and specifically to such devices used in the consumer and healthcare industry for remote patient communication and emergency situations.

Elderly persons are not typically technically savvy; nor are they adept at using portable devices. Poor eyesight and physical dexterity leave them unable to use most devices. The notion of using such devices oftentimes strikes the elderly with fear resulting in reluctance or refusal to use such devices. Children share many of these characteristics, and therefore can also benefit from this invention.

Seniors are constantly exposed to a barrage of emerging technologies that can overwhelm the aging brain, and are contending with diminishing manual dexterity and functionality of their nervous system and musculoskeletal physiology. The present invention has a wide range of novel features and technical advancements to facilitate simplified uniform operation that improves the quality of life and extends independent living for as long as practical. The skill sets learned in their home and other environments will eventually transition with them into assisted living facilities and/or nursing homes, hospitals, or acute care facilities without having to relearn or simply give up on what can pose daunting mental and physical learning obstacles.

The ubiquitous nature of the internet, and technologies that take advantage of it, presents opportunities to remotely engage and/or help the elderly who are oftentimes unable or unwilling to travel. Thus, there is a need for devices and systems that take advantage of modern technology, and are usable by the elderly.

The present invention is a novel wearable mobile personal emergency response system (mPERS) smart pendant for providing timely healthcare and personal services to the user. In addition to mPERS signaling, the pendant includes wireless automatic signaling in assisted living and other medical facilities, and personal residences for home healthcare and other personal services, intended to be compliant with all of the current UL, standards: UL 1637 Home Health Care Signaling Equipment (as applicable) UL 2560 Emergency Call Systems for Assisted Living and Independent Living Facilities, and UL 1069 Hospital Signaling and Nurse Call Equipment; and the forthcoming UL 1698 standard that is being developed by the UL Standards Technical Panel for Personal Emergency Response Equipment (STP 1698) UL 1698 Personal Emergency Response Equipment. The intended user of the present invention is an individual in an assisted living facility (ALE) or other medical facility, under home healthcare supervision in their residence, or a parent or child that is being cared for by family members or friends. The operation of the present invention is intended to require minimal physical dexterity, eyesight, mental acuteness, and/or specialized training to setup, operate, or interconnect with the present invention.

Some features of one embodiment of the present invention include: The device (aka mobile device, or pendant) has only one mechanical button (aka hardware button, or control button) that is used to initiate a call for urgent assistance to a central station monitoring center, ALF call notification station, ALE designated number, nurse call station, and/or caregiver; continuous automatic fall detection initiates an emergency call for assistance to a central station monitoring center, ALF call notification station, ALF designated number, nurse call station, and/or caregiver; automatic power on, power recovery, power management, and battery monitoring features with low battery status signaling to the central station monitoring center, ALF call notification station, ALF designated number, nurse call station, and/or caregiver; an LCD touch screen (aka LCD) is automatically turned on by rotating the pendant for normal viewing (see FIGS. 3A through 3D), by tapping on the pendant, by shaking the pendant, or by simply moving the pendent (in a user-sleep mode); the LCD turns off automatically and the processor(s) go to a low power mode when the pendant is rotated back to the normal resting position (aka dormant mode), suspended by the lanyard, or after a programed timeout due to inactivity in order to conserve battery capacity; large high contrast fonts and capacitive touchscreen buttons (distinguished from mechanical button) on a high brightness LCD with automatic and remotely controllable (by caregiver) brightness control that offers several advantages, including allowing the caregiver to illuminate the user's face via the LCD brightness; amplified speaker with local volume control (slider on LCD) and remotely controllable by a caregiver; wireless battery charging from any Qi compliant battery charger; wireless interface to accessories, computers, smartphones, etc. (optional Bluetooth); Remote pendant setup and control by authorized caregivers; the touch screen having icons or control components that can be remotely acted upon by a caregiver (e.g. temporarily enlarging the size of the icon, or temporarily amplifying the brightness of the icon), can facilitate the remote caregiver teaching the user how to use the present invention.

Remote Setup

In one embodiment, the present invention can be remotely programmed or setup by a caregiver, or family member, with the following information and/or features: personal account information; emergency call phone numbers including call sequence, timeouts, automatic messages, etc; audio/video calling configuration to designated caregivers, family members, or friends for two-way audio or audio/videoconferencing; default LCD brightness and contrast controls: default video digital zoom value; default speaker volume; default display profile, font colors, font contrast, and language (English, Spanish, French, German, custom, etc.); alert types (ring tones, alert tones); individual volume controls: LCD display timeout controls; default wake up alarms, alarm sounds; display wakeup controls (tilt angle, tap and shake sensitivity, timers, etc.); fall detection profile and sensitivity; default GPS locations: ALF facility location, home location, and other locations; GPS tracking features; event logging features; pedometer features, and sensitivity controls.

Remote Control

In one embodiment, the present invention can be remotely controlled by a caregiver, or family member, as follows:

Speaker volume: if the user expresses difficulty in healing the caregiver during a two-way audio call, they can adjust the audio volume with an on-screen touch slider, or the remote caregiver can remotely adjust the audio volume on the device during the call. The remote caregiver can also adjust the default audio volume for all calls (see “Remote Setup”).

LCD brightness: if the user expresses difficulty in seeing their LCD display during a video call, they can adjust the LCD brightness with an on-screen touch slider, or the remote caregiver can remotely adjust the LCD brightness on the pendant during the call from their application on a remote device. The remote caregiver can also adjust the default LCD brightness and contrast (see “Remote Setup”).

Video digital zoom: the remote caregiver can adjust the video digital zoom from their application to see a close up view' of the user's face, skin, eyes, etc. for general viewing or diagnostic purposes. The remote caregiver can also adjust the default video zoom value for all video calls (see Remote Setup).

Pendant Locate: remote caregiver can make the pendant vibrate and/or sound a loud beeping sound so that the pendant can be located by the user. The remote caregiver can also initiate a video call to observe the camera, view and hear sounds in the vicinity of the pendant to assist in locating the pendant.

Unattended audio or audio/video conferencing: The remote caregiver (or family member that is concerned or otherwise unable to contact the user) can initiate and automatically connect an audio or audio/videoconference (the camera, microphone, and speakers can be remotely activated) with the pendant. The pendant user does not need to answer or authorize the call (in some embodiments), or rotate, tap or shake the pendant to answer the call. In one embodiment, the user is presented with a warning on the LCD that the device is about to be remotely controlled, so that the user can override or stop said control.

MCU Embedded Software Summary

In one embodiment, the following embedded software functionality is available in the MCU: low power MCU modes are optimized for the various scenarios described herein; power on, watchdog recovery, or recovery from discharged battery features are also incorporated; accelerometer configuration; accelerometer magnetometer (or gyro) configuration; audio CODEC configuration; cellular module configuration; GPS configuration; pressure/altitude sensor configuration; APU reset; accelerometer fall detection algorithm; accelerometer shake detection algorithm; accelerometer magnetometer (or gyro) pendant orientation/tilt detection algorithm to wake up APU; call button debounce logic to wake APU (consideration for RC network); MCU communication software for mPERS data signaling, monitoring center server acknowledgment handshake, and remediation in the event of communication failures; MCU initiate and control 2-way audio call, and remediation in the event of call failure; MCU interface to APU; valid cellular connection annunciation with bi-color LEDs; event logging in I2C FLASH memory; battery SOC and notification to server or APU data sharing; prerecorded audio annunciations.

Other Objects and Advantages

One object of the present invention is to address signaling/communication and GPS & non-GPS/horizontal location, indoors not at home/vertical location, and accuracy/minimum # of satellites, including considerations implicated by the development of UL 1698.

As a mobile device, the location of a reportable event must be provided to the monitoring center. The location may be determined utilizing various technologies such as GPS, beacons, Wi-Fi, etc. Since the device of the present invention by nature is mobile, communications and location may not always be determined with 100% accuracy. Therefore, it is important to provide the user and call center with an indication whether cell service is available or not, an indication that a call for help is in progress, and whether or not the call was successful. In addition, since current location may not be determined accurately, the device should be capable of reporting the last known location and the time of known location to a monitoring center when a call for help is made. Due to the vagaries of mobile communications, the elapsed time between the call being initiated and terminating into the monitoring center should also be reported.

The communications link is vital. The device must ping (test connectivity) the database at least once every 24 hours. If connectivity fails, the device must indicate that it is inoperable or service is not available; the call center is placed on notice by failure to receive the requisite confirmation.

Summary of mPERS Signaling (also discussed in Detailed Description).

Upon activation or detection of a reportable event, the mPERS (mobile personal emergency response system) shall provide necessary information to the monitoring center to effectively provide needed assistance. “mPERS System” is defined as a stand-alone mobile PERS capable of transmitting all pertinent alarm data directly to the monitoring center, or a mobile PERS linked together with a backend database which relays the pertinent information to the monitoring center. Data communications must use a closed loop or ACK/NAK protocol between the device, backend and/or the monitoring center.

“Pertinent data” shall include the following fields:

- a. Account Field: A data field that uniquely identifies the account or customer in need.
- b. Alarm Field: A data field or fields that uniquely identify the alarm event or events triggering activation.
- c. Last Known Location: Indicates the last known X-Y location.
- d. Last Known Location Time: Provides the time stamp of the last known location.
- e. Current Location Field: specifies the X-Y location (latitude/longitude) of the device when activated. This may be the same as last known location. If the mobile device is linked to a stationary device at a known location, i.e. customer's home, or specific room in a specific building, the location field may be filled with a keyword to indicate the customer's specific known location.

Data provided to the monitoring center shall be sufficient to give the monitoring center the ability to determine when the reportable event occurred.

Two-Way Voice Communications.

Once the monitoring center receives the signaling information from the mPERS, the monitoring center must have the ability to communicate with the user by voice for compliance with UL 1698.

Determination of Location.

X-Y location shall be determined electronically using methods such as GPS, beacons, cellular, Wi-Fi, etc. and shall be reported as Latitude and Longitude m accordance with UL 1698. In addition, if a user-predefined location is known, the location may be reported as such. For example: HOME. If determinable, more specific locations may be reported such as HOME-KITCHEN or HOME-BASEMENT. Vertical (Z axis) location can be incorporated m accordance with known techniques. Generally, location accuracy is proportional to the number of ascertainable GPS satellites, or cellular towers. Thus, it is an object of this invention to ascertain location in accordance with best known techniques.

MCU 22 has access to sufficient volatile memory for all runtime use, and sufficient non-volatile memory for program space. MCU 22 is capable of continuously monitoring the activity of all sensors and interrupts with which it interfaces, including detection of “wake up” conditions that require subsequent activity by the MCU or APU and/or their connected peripherals. MCU 22 controls cellular module 24 activities. In one embodiment, MCU 22 comprises cd Qualcomm/NXP Kinetis KL17 microcontroller, and serves as the primary point of power consumption management of the device. In one embodiment, MCU non-volatile memory 25 is intended exclusively for storing configuration information and event logging, and interfaces with the MCU via serial peripheral interface (SPI) 26.

In one embodiment, camera 14 comprises a CCD-based camera that utilizes a dual-lane MIPI interface 7 with APU 20, and has a minimum resolution of 5 megapixels. Ambient light sensor (ALS) 13 is intended for use in controlling the brightness of the Video Display, and interfaces with APU 20 via 12C 5. A 3-axis accelerometer is used tor “wake up on tilt” functions and fall detection algorithms, and interfaces with MCU 22 via I2C 5. In one embodiment, gyroscope 27 comprises a 3-axis MEMS gyroscope intended for use in “wake up on tilt” functions and fall detection algorithms, and interfaces with MCU 22 via 12C 5.

Ambient pressure sensor 28 is intended for use in altitude measurement, and interfaces with MCU 22 via I2C 5. In one embodiment, WiFi communication module 17 is 802.11a/b/g/n compliant, and utilizes and accesses APU 20 via SDIO interface 9, and Bluetooth (BT) communication module 23 comprises a BT 4.0+EDR communication module, interfaces with APU 20 via UART 1, and is integral to the WiFi module. Cellular communication module 24 is operatively connected to SIM card 30, is capable of “3G” communication, and interfaces MCU 22 via UART 29 as the primary control channel; Cellular communication module 24 interfaces APU 20 via USB as a data channel rather than the primary control channel for the cellular module. Cellular communication module 24 interfaces with global positioning system (GPS) component 31, working in conjunction with the Global Navigation Satellite System (GNSS).

In one embodiment, video display component 2 comprises a 2.8″ (diagonal) class LCD video display having a minimum resolution of 240×320 pixels, with an 18-bit RGB video interface with APU 20; capacitive touch panel 32 is overlaid on video display component 2, the combination generally referred to herein as “touch screen”. In one embodiment, call button 12 is the only hardware button externally accessible to the device user.

Audio input/output component 15 is operatively connected to microphone 33 and speaker 34, all of which are minimally capable of voice quality audio. In one embodiment, microphone 33 comprises a MEMS microphone. Audio input/output component 15 is controllable by MCU 22, and is switchable between application input/output, microcontroller input/output, Bluetooth module input/output, and cellular module input/output, all via I2S 6.

In one embodiment, a multi-color light emitting diode (LED) 35 is used communicate to the user the status of the device in various conditions. In other embodiments, multiple LEDs are used (e.g. one red and one green, or red, green, and blue). LEDs interface MCU 22 via PWM communication components.

In one embodiment, power management integrated circuit component (PMIC) 36 comprises a single-chip PMIC, the configuration of which shall be performed MCU 22; PMIC 36 interfaces MCU 22 via an I2C interface; PMIC 36 controls the order of power-up for APU 20 and all peripherals; power-up occurs following initial power-up of the device or following an indication from the MCU to wake up any portion of the device; battery component 37 comprises a rechargeable 1700 mAh lithium-based battery, charged via wireless charging component 38; a “gas gauge” function capable of determining the charge state of the battery, interfaces MCU 22 via an I2C interface.

Pendant Idle (Aka “Dormant”, “Low Power”) Mode

In one embodiment, mobile device 39 (aka pendant) is suspended from the neck of the user by a lanyard. In the idle mode, the LCD is turned off and the processor(s) (MCU 22 in one embodiment) is/are in a low power mode. Cellular module 24 periodically pings the local cell towers, verifies if cellular service is available, and wakes up MCU 22 to provide a visual indication via a flashing LED (green in one embodiment) that cell service is available. A low current bi-color LED is flashed once per second (time interval is programmable) to conserve battery power. The bi-color LED flashes red when cellular service is not available (see “mPERS Signaling” and the proposed UL1698 guidelines). GPS component 31 periodically stores the user's current location in accordance with the proposed ULI698 guidelines (see “mPERS Signaling” and the proposed UL1698 guidelines).

Accelerometer component 41 interrupts MCU 22 if a pre-determined and/or programmable acceleration threshold is exceeded. MCU 22 wakes up and performs a fall detection assessment to determine if the user has fallen. If a fall has been detected, the MCU logs the event and initiates an emergency call to monitoring center 40 (see “mPERS Signaling”). If a fall has not been detected, the MCU logs the event and performs a shake assessment to determine if the user shook the pendant to wake up the device (aka initiate smart pendant operation). Otherwise, the MCU logs the event and returns to a low power mode. MCU 22 is interrupted if a double tap has been detected. The MCU logs the event and interrupts APU 20 to turn on the LCD and touchscreen for smart pendant operation.

Gyroscope 27 interrupts the MCU if a pre-established tilt angle or orientation threshold is exceeded (e.g. FIGS. 3A through 3D). MCU 22 wakes up and performs a pendant orientation assessment to determine if the pendant has been positioned for using smart pendant operation (aka “active mode”). If the pendant has been positioned for small pendant operation, the MCU logs the event and interrupts APU 20 to turn on the LCD and Touchscreen for smart pendant operation. Otherwise, the MCU logs the event and returns to a low power mode.

Depressing call button 12 interrupts MCU 22 to wake up and perform an algorithm to debounce the Call Button signal in accordance with known techniques. If a Call Button push has been validated, the MCU logs the event and initiates mPERS signaling as discussed herein. Otherwise the MCU logs the event and returns to the low power mode.

Pendant Orientation Assessment

Generally, pendant orientation assessment comprises detecting if the device is moved from a dormant mode to an active mode. In one embodiment, the active mode comprises being visible to a user positioned between a substantially standing position through a substantially siting position; the dormant mode comprising the device not being in the active mode. In one embodiment, the dormant mode comprises the device is not being held by the user, and the active mode comprises the device not being in the dormant mode.

In one embodiment, the active mode comprises the touch screen being oriented in the range of: a relatively >0 degree horizontal position (the touch screen facing upwardly and slightly towards the user), through a substantially 135 degree position (the touch screen facing slightly downwardly and towards the user; the dormant mode comprises the touch screen being oriented in the range of: a substantially >135 degree position, through a relatively 180 degree horizontal position (the touch screen facing downwardly towards the floor), through a relatively 270 degree vertical position (the touch screen facing away from the user), to a relatively 360 degree horizontal position (the touch screen facing upwardly towards the ceiling).

It should be noted that in some embodiments, the touch screen being positioned so as to be viewable by the user contemplates the user not lying in bed. Alternatively, a user-sleep mode (i.e. distinguished from a device sleep mode) can be invoked by the user wherein the device “wakes up” (the touch screen is activated) upon movement.

In the sleep mode, it is contemplated that the device is placed within arms-reach of a user lying in bed and is activated if the user grabs the device. Thus, the device might be relatively horizontal and downwardly facing as the user is lying in bed holding the device above them.

Smart Pendant Operation

As depicted in E7ig. 7, the device is maintained in a dormant mode 100 until a pre-determined event 101 occurs; upon the occurrence of the pre-determined event, the touch screen is temporarily activated 102 for a pre-determined interval; the touch screen is deactivated and the device resumes the dormant mode after the pre-determined interval unless a confirmation input is received from a user 104, in which case the wake up process is continued 105; the confirmation input received from the user comprises presenting the user with a control component 103 whereby the user confirms the pre-determined event has occurred. In one embodiment, the control component is a hardware button. In another embodiment, the control component is a software button.

In one embodiment, upon detection of a pre-determined event as described herein, (e.g. the device being shaken, the touch screen being positioned so as to be viewable by the user, fall detection, touch screen double tapped by the user, control button pushed by the user), a high contrast “Start Screen” (e.g. FIG. 5) is displayed for 10 seconds (this interval being programmable). If the user does not touch the “Start” button the LCD turns off and the MCU and APU return to low power modes to conserve battery life. All features of the Stall Screen are programmable to customize or unclutter the display.

It should be noted that in some embodiments, a fall detection event does not require user authentication/confirmation; the advantage being that an unconscious user will not be able to confirm the event. Additionally, some embodiments contemplate the control button being pushed in a panic state of mind which does not necessitate authentication. Otherwise, the start screen is only displayed for a brief time to allow the user to decide if they want to use the smart pendant features. This prevents the processors and LCD display from staying on for a prolonged time, thereby draining the battery (e.g. if the display is unintentionally turned on while moving, sitting or lying down, etc).

The brief interval can be utilized by the user to quickly check: the time of day, if messages are waiting, the day of the week, date, current local weather outside, the user's name (also for mentally challenged users), engaging active mode to interact with the settings menu, changing the contrast to a “light” mode to provide a LCD brightness level flashlight or reading light.

In one embodiment, an “airplane mode” can be activated. In one embodiment, any of the screen icons can be hidden or deactivated to prevent accidental use.

mPERS Signaling

If a fall has been detected, or the user presses call button 12, (some embodiment require authentication while others do not) MCU 22 initiates mPERS (mobile personal emergency response system) signaling comprising:

1. MCU 22 logs the time and type of event (fall detected or user pressed the Call Button).

2. MCU 22 signals the monitoring center backend servers via the cellular module with the following:

- a. Account Field: a data, field that uniquely identifies the account or customer in need.
- b. Alarm Field: a data field or fields that uniquely identify the alarm event or events triggering activation.
- c. Last Known GPS Location: indicates the last known GPS latitude/longitude (X-Y) location.
- Note: for all of the GPS locations, the location may be the cell tower CELL-LOCATE location from the cellular tower(s) if the GPS location was not available. Location data obtained from CELL-LOCATE services must be identified due to the inherent inaccuracy of the data.
- d. Last Known GPS Location Time: provides the time stamp of the last known GPS location.
- e. Current GPS Location Field: specifies the X-Y location of the device when activated. This may be the same as Last Known Location.
- f. The MCU vibrates the pendant and plays a prerecorded tone and audio message that a call for help is in progress.

3. The monitoring center backend server must communicate an acknowledgment and timestamp that the data was received.

4. The MCU logs the acknowledgement received from the monitoring center backend server, plays a prerecorded audio message that help is on the way and/or a two-way audio call will be initiated.

5. The MCU initiates a two-way audio call with the monitoring center.

6. If the monitoring center server does not acknowledge the MCU signaling within a programmable time limit the MCU will attempt to retransmit the request. If the MCU retransmitted request is not acknowledged by the monitoring center server, the MCU will enter a prescribed fallback signaling mode (with consideration for Wi-Fi signaling). Similarly, if the two-way audio call is not completed, the MCU wall enter a prescribed fallback two-way audio calling mode (with consideration tor a two-way audio call via Wi-Fi. Also see “Two-Way Voice Communications”, herein).

In one embodiment, a portable and wearable device comprises: touch screen 2; microphone 33; speaker 34; camera 14; hardware button 12; GPS component 31; and processing and memory sufficient to perform the steps of: maintaining the device in a dormant mode until a pre-determined event occurs 106: while in the dormant mode: periodically ascertaining and logging the physical location of the device 107: periodically monitoring for at least one communication channel between device and remote location 108, and causing alert conditions locally (e.g. LED flashes, screen icon appears, sound vibration), and at a remote location (personnel are alerted and protocol initiated to contact user), if a communication channel (e.g. wifi, cellular, RF) between the device and the remote location ceases to be available during a pre-established periodic interval 109; upon the occurrence of the pre-determined event: enabling selective remote operation (cause noise, vibration, flashing LED or screen, audio annunciation) and/or monitoring (remote person looks through camera, listens from microphone) of the touch screen, the microphone, the speaker, the camera, or the GPS component 110.
