In one embodiment, an apparatus () is presented that detects wireless signals from external devices () that uniquely identify each of the external devices, records, in memory (), information about the external devices without access to an external database, and compares information from the external devices to determine a relative location of the wearable device without using additional, power-hungry position location functionality if there is a threshold match in the compared information. In some embodiments, the invention uses the determined relative location to trigger an action at another device. The invention, using self-contained functionality, enables improvements in same location or home location determination accuracy, memory conservation, and power consumption.

Wireless location recognition for wearable device

A geo-fencing system () includes a base device () configured to create a virtual fence () around the base devise that bounds a safe zone (). The geo-fencing system further includes a wearable device () initially located within the safe zone. The geo-fencing system further includes a processor configured to execute a dynamic adaptive control algorithm that computes at least one operating parameter for at least one of the base device and the wearable device based on a dynamic and adaptive combination of different signals indicative of distance measurements between the wearable device and the base device computed by the at least one of the base device and the wearable device. The processor conveys the at least one operating parameter to the at least one of the base device and the wearable device, which employs the at least one operating parameter for operation and determination of subsequent distance measurements.

Geo-fencing based on multiple signals and configuration

In one embodiment, an apparatus is presented that detects wireless signals from external devices that uniquely identify each of the external devices, records, in memory, information about the external devices without access to an external database, and compares information from the external devices to determine a relative location of the wearable device without using additional, power-hungry position location functionality if there is a threshold match in the compared information. In some embodiments, the invention uses the determined relative location to trigger an action at another device. The invention, using self-contained functionality, enables improvements in same location or home location determination accuracy, memory conservation, and power consumption.

A Personal Emergency Response System (PERS) includes a call device () with a call button (), LAN (), WAN (), and locator service(s) (). The PERS further includes a hub or gateway device (). The call device is programmed to periodically send transmissions to the hub or gateway device using the LAN, recognize based on the transmissions that the call device is no longer in a home geo-fence, and transition to communicating using the WAN in response to recognizing that the call device is no longer in the home geo-fence. The transition also includes turning on the locator service(s). The call button triggers the call device to contact the hub or gateway device using the LAN, or a PERS call center when using the WAN. A speaker () and microphone () are built into the call device for use when communicating using the WAN.

In home transition for data and power management of personal emergency response system (PERS) device

A mobile button device () comprises a call button (), a local wireless link () to a communicator (), and a cellular connection (). The mobile button device is programmed to perform an alarm reporting method including: originating an alarm by sending the alarm via the local wireless link to the communicator for alarm reporting by the communicator; after sending the alarm to the communicator, monitoring alarm reporting status via the local wireless link to the communicator; and reporting the alarm via the cellular connection in response to the monitoring determining that the communicator failed to report the alarm. For example, the monitoring may include polling the communicator via the local wireless link and the monitoring determines that the communicator failed to report the alarm if the polling indicates the communicator is unavailable () or a timeout condition () is reached.

Alarm reporting fail over mechanism

A mobile call device () for use in conjunction with a Personal Emergency Response System (PERS) includes a cellular radio () configured for voice communication () and data transmission () and a call button (). The mobile call device is programmed to: send a machine-to-machine (M2M) message () from the cellular radio to a PERS call center () via a M2M server (). The M2M message includes at least PERS subscriber or mobile call device identification information, and may further include current location information acquired by one or more locator services () of the mobile call device. After sending the M2M message, the mobile call device is further programmed to receive and conduct a voice call () originating from the PERS call center. The mobile call device may be further programmed to initiate a voice call to a Public Safety Answering Point ().
