Abstract

Official abstract text for this publication.

A power delivery method and system for powering a headset. A power signal is combined with an audio signal to form a composite signal that is communicated over a shared channel to the headset. The power signal is generated by modulating a carrier signal with a modulation signal. The modulation signal is derived from the amplitude of the audio signal so that the peak levels of the composite signal do not exceed the maximum allowable output of an audio I/O circuit driving the headset.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of providing power to a headset, the method comprising: processing an audio signal having a time-varying amplitude; generating a power signal by amplitude modulating a carrier signal with a modulation signal that is formed in a complementary fashion to the time-varying amplitude of the audio signal; and summing the power signal with the audio signal to form a composite signal having an amplitude limited to a maximum amplitude value.…
