Claim 18:
19. The apparatus of claim 17, wherein the sensor circuitry includes a blood pressure (BP) sensor configured and arranged to provide a bio-signal indicative of BP among the plurality of bio-signals and the processing circuitry is configured and arranged to:
determine the dominant oscillations as the function of the sleep stages and time by:
detecting the peaks in BP using the PSD of the bio-signal indicative of BP;
determining the respective dominant frequency associated with BP based on the detected peaks in the PSD of the bio-signal indicative of BP;
decomposing the bio-signal indicative of BP in the dominant frequency using a respective filter of the filters; and
determining the optimal windows for stimulation based on the decomposed bio-signal indicative of BP in the dominant frequency.
