Patent ID: 7174206

Claim:
A method for detecting poor signal quality and for phase shifting neurological signals received from the plurality of monitoring elements, comprising the steps of: (a) receiving a first neurological signal from a first monitoring element and a second neurological signal from a second monitoring element; (b) processing the first neurological signal to generate a plurality of data points for the first neurological signal in a moving time window; (c) detecting whether the first neurological signal has poor signal quality by determining that an amount of the data points exhibiting poor signal quality within the moving time window has exceeded a predetermined threshold; (d) if the first neurological signal has poor signal quality, ignoring the first neurological signal experiencing poor signal quality in signal processing; and (e) if the first neurological signal does not have poor signal quality, performing (i) sampling the first and second neurological signals at different time instances resulting in a time shift between the first and second neurological signal samples; and (ii) time shifting signal samples of the second neurological signal to correct for the time shift so the second neurological signal is synchronized with the first neurological signal.
