Patent ID: 8824696

Claim:
A headset comprising: a first acoustic sensor mounted on the headset having an output signal; at least one second acoustic sensor mounted on the headset having an output signal; modulator circuitry configured to receive a carrier signal and coupled to receive the output signal of the second acoustic sensor, the modulator circuitry configured for modulating a carrier signal with the output signal of the second acoustic sensor to provide a modulated output signal reflective of the output signal of the second acoustic sensor; combining circuitry coupled to receive and combine the output signal of the first acoustic sensor and the modulated output signal to produce a composite downlink signal that reflects the output signals of the first and at least one second acoustic sensors for transmission over a common conductor; at least first and second electrical connections configured for providing a connection to a terminal device; and at least one of the electrical connections coupled with the combining circuitry for handling the composite downlink signal and directing the composite downlink signal to the terminal device.
