Patent ID: 7818036

Claim:
A wireless device for use with a half-duplex wireless communications device, the wireless device comprising: a microphone assembly adapted to receive audio information from a user; a switch; and an induction transceiver adapted to wirelessly transmit at least one signal through a magnetic induction link to one of the half-duplex wireless communications device and an adapter coupled to the half-duplex wireless communications device, wherein the at least one signal wirelessly transmitted through the magnetic induction link comprises information indicating a status of the switch and information representative of at least a portion of the audio information received at the microphone, wherein, if the information indicating the status of the switch indicates that the switch is engaged, the information indicating that the switch is engaged is used to control the half-duplex wireless communications device to enter a half-duplex transmission mode for the half-duplex wireless communications device to wirelessly communicate the at least a portion of the audio information to another wireless communications device, and wherein a disengagement of the switch does not prevent the at least one signal wirelessly transmitted by the induction transceiver from comprising the information representative of at least a portion of the audio information.
