Abstract:
Methods and apparatus to determine a state of a media presentation device are disclosed. Example disclosed methods include generating a first set of weighted coefficients based on first audio received by first and second microphones at a first time. Example disclosed methods include generating a second set of weighted coefficients based on second audio received by the first and second microphones at a second time after the first time. Example disclosed methods include comparing the first set of coefficients and the second set of coefficients to generate a similarity value. Example disclosed methods include, when the similarity value satisfies a threshold, determining that the media presentation device is in a first state. Example disclosed methods include, when the similarity value does not satisfy the threshold, determining that the media presentation device is in a second state.

Claim (Index 13):
The computer readable storage medium of  claim 12 , wherein the instructions, when executed, cause the machine to generate the error signal by generating the error signal according to X e (n)=X d (n)\u2212Y 0 (n), the X d (n) representing an audio sample and the Y 0 (n) representing a summed filter output of multiple audio samples, the n being an iteration index, and the first set of weighted coefficients to be adjusted based on the error signal according to W m (n+1)=W m (n)+\u03bcX e X m (n), the W m (n+1) and the W m  being weight coefficients and the \u03bc being a learning factor.
