Abstract: An audio player device includes a digital-to-analog converter (DAC), a startup circuit, a multiplexer and an output amplifier. The DAC converts audio data into a first signal and a second signal. The startup circuit gradually increases a level of a startup voltage according to a reference voltage during a predetermined period. The multiplexer outputs the startup voltage as a control voltage during the predetermined period, and switches to output the reference voltage as the control voltage after the predetermined period has elapsed. The output amplifier generates an audio signal according to the control voltage, the first signal and the second signal. The control voltage is used to set a common mode voltage of the output amplifier.

Abstract: Location of objects associated with radio frequency (RF) tags in a particular subspace or room within a predefined master space. A plurality of multi-channel radio beacons (e.g. Bluetooth Low Energy or BLE) transmit signals into the master space. A survey operation is conducted to detect RF signals, e.g. RSSI values, from the beacons within predefined subspaces within the master space. Data from the survey operation is used to construct one or more machine learning (ML) data models. Each object to be located is provided with a dual mode RF tag that receives beacon signals when placed into a subspace and activates (e.g. by motion or command) to transmit data containing RSSI of beacon signals to an object location system. The system runs the received beacon signals against the ML data models and returns a prediction candidate of a particular subspace corresponding to a likely location of the tag and object.
