Abstract:
An off-head detection system for an in-ear headset comprises an input device that receives an audio signal, a feed-forward microphone signal, and a driver output signal; an expected-output computation circuit that predicts a value of the driver output signal based on a combination of the audio signal and the feed-forward microphone signal from the signal monitoring circuit, and off-head data from the off-head model; and a comparison circuit that compares the observed output signal provided to the driver and the computed expected output to determine an off-head state of the in-ear headset.

Claim (Index 16):
The off-head detection system of  claim 15 , wherein comparing the output signal to the estimated output signal comprises comparing the output signal at one or more predetermined frequencies to the estimated output signal at the one or more predetermined frequencies.
