Abstract: Aspects of the present disclosure provide a power activation module for powering one or more wearable electronic components. The power activation module includes a switch configured to provide a path for current flow between a battery associated with the power activation module, the one or more wearable electronic components, and a ground terminal. The power activation module also includes a sensor configured to detect whether a signal is applied to the sensor and, based on the detection, output a first digital output signal for controlling, at least in part, the switch to control the current flow from the battery to the one or more wearable electronic components. The power activation module also includes a lock pin configured to receive a lock signal, wherein when the lock signal is received, the switch is locked to allow current flow from the battery to the one or more wearable electronic components.

Abstract: Aspects of the present disclosure provide techniques for improving a communication range of an analyte sensor system. The analyte sensor system may include a analyte sensor configured to generate analyte data associated with analyte levels of a user of the analyte sensor system, an antenna system comprising a plurality of antennas, a transceiver circuit configured to transmit the analyte data to a communications device via one or more antennas of the plurality of antennas of the antenna system, a switching device configured to selectively couple the one or more antennas to the transceiver circuit, and a circuit board configured to operatively connect the transcutaneous analyte sensor with the transceiver circuit.
