Abstract: Various data (e.g., audio) relay devices and methods are disclosed. An exemplary data relay device may comprise a first chip configured to wirelessly connect to one or more physical sink devices, and a second chip. The second chip may be configured to create one or more virtual sink devices configured to be wirelessly detectable by one or more physical source devices, in response to the one or more physical source devices wirelessly connecting to the second chip, obtain data from the one or more physical source devices, and transmit the data to the first chip, causing the first chip to relay the data to the one or more physical sink devices.

Abstract: Devices, systems, and methods are disclosed for detecting falls and transmitting notifications. One embodiment includes a wearable device. The wearable device may include a first sensor configured to collect acceleration data, and at least one of a second sensor configured to collect pressure data or a third sensor configured to collect temperature data. The wearable device may also include an antenna and a processor. The wearable device may also include a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to receive the acceleration data and at least one of the pressure data or the temperature data, process the acceleration data and at least one of the pressure data or the temperature data, and control, when the processor determines that a person falls, the antenna to transmit a signal.
