A system for communicating pitch selections wirelessly from a wireless transmitter has a coded signal generator that generates coded signals in accordance with selected pitch types. A receiver decodes the received coded signals, selects an audio file based on the received coded signal and generates an audio signal announcing the selected pitch type based on the transmitted selected pitch type in accordance with the received coded signal. The audio signal is transduced by a bone conductor transducer so that the player can hear the announced selected pitch type through bone conduction.

A mobile conversion apparatus for docking cellular data devices including push-to-talk over cellular (PoC) devices. The apparatus includes a Universal Serial Bus Type-C (USB-C) connection. The conversion apparatus is designed and configured to couple the PoC device to a mobile communications interface within a vehicle using the USB-C connection. The PoC device is horizontally insertable into the conversion apparatus exposing only the top of the PoC device leaving only the display and knob of the PoC device exposed on the face of the conversion apparatus. In this manner, the conversion apparatus effectively docks the PoC device, thereby connecting the two together via the USB-C connection.

A near-field communication (NFC) receiver includes first and second input terminals for receiving first and second input signals having a modulated signal portion and a carrier signal portion. The receiver includes a digital-to-analog converter (DAC), a mixer, a track-and-hold (T&H) circuit, an amplifier, and an analog-to-digital converter. The mixer has a first input coupled to receive the first and second input signals and a second input coupled to receive a low frequency current from the DAC. The mixer subtracts the carrier portion from the first and second input signals using the DAC current at a level determined using a DSP in a feedback loop to approximate the carrier. The T&H circuit has an input coupled to receive the combined current and an output to provide a series of output samples. The ADC is coupled to receive the amplified output signal and to provide a digital representation of the amplified output signal.
