Abstract:
A method of detecting and processing time-dependent signals from a stimulus source, the method comprising the steps of:a) detecting with a detector the signal energy from stimuli from the stimulus source at predetermined time points; b) processing the output signals of the detector to produce a sensor state x(t) at each time point tin a collection of predetermined time points, said sensor state x(t) including one or more numbers; c) saving in computer memory said output signals of the detector and said sensor states x(t) at each time point in the collection; d) processing the saved sensor states x(t) to produce a representation of each sensor state x of a predetermined collection of sensor states in the space of possible sensor states, each said representation including one or more numbers and said processing of said saved sensor states x(t) having the property that said representation of each said sensor state x is approximately the same as the representation of the transformed said sensor state xâ€²=xâ€²(x), said representation of said transformed sensor state xâ€² being produced from the transformed time series of said saved sensor states xâ€²(t)=xâ€²[x(t)], xâ€²(x) being a transformation on the space of possible sensor states; e) saving in computer memory said sensor states in said predetermined collection of sensor states and said representations of the sensor states in said predetermined collection of sensor states; and f) processing at least one of the saved output signals of the detector and the sensor states in said predetermined collection and corresponding representations to determine aspects of the nature of the stimuli producing the sensor states in said predetermined collection.
