A hearing aid including a hearing aid antenna assembly, a transceiver, and an acoustic transducer is provided. The hearing aid assembly includes a resonant loop antenna, a coupling mechanism such as a primary loop, and an electrically conductive assembly. The resonant loop antenna forms an aperture that is arranged to be substantially parallel to a head of the wearer when the hearing aid is worn. The coupling mechanism is configured to transfer RF energy between the transceiver and the resonant loop antenna. The resonant loop antenna excites the electrically conductive assembly. The electrically conductive assembly includes a battery shield. The resonant loop antenna, the coupling mechanism, and/or the electrically conductive assembly are formed in one or more conductive layers of FPCB. The resonant loop antenna includes a course tuning capacitor in series with a fine tuning capacitor. The primary loop includes a resonating capacitor.

An embodiment of an antenna module includes a substrate, a first antenna, and a second antenna. The first antenna is disposed on the substrate and is configured to radiate a first signal having a wavelength and a first polarization. And the second antenna is disposed on the substrate and is configured to radiate a second signal having the wavelength and a second polarization that is approximately orthogonal to the first polarization. For example, such an antenna module can include, as the first antenna, a T antenna configured to transmit and receive data that forms a first part of a MIMO-OFDM data symbol, and can include, as the second antenna, an F antenna configured to transmit and receive data that forms a second part of the MIMO-OFDM data symbol.

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.

In a personal emergency response system (PERS), a personal help button (PHB) () includes a call button (), a motion sensor (), and a transmitter or transceiver () for transmitting a wireless call signal responsive to pressing the call button. An electronic processor () performs a compliance monitoring process () at successive compliance check times, each including: acquiring motion sensor data over a compliance data acquisition time interval; determining whether the PHB has moved since the last compliance check time; and assessing compliance based at least in part on the determination of whether the PHB has moved. The determining may include determining an orientation change of the PHB since the last check time. Alternatively, compliance may be monitored by detecting and logging wake-up interrupt events that cause the motion sensor to switch from a low-power mode to an operational mode.

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.
