Patent ID: 8527041

Claim:
A stimulation system for indicating stimulation signals to a user, comprising: at least one heart beat sensor for converting measured heart beats into a signal; a processing circuit configured to process the measured heart beat signals; and a user interface configured to indicate stimulation signals to a user; wherein the processing circuit is configured to: calculate time intervals between detected heart beats and register a predetermined number of successive calculated heart beat time intervals, predict a heart beat time interval (a) between (a)(i) a detected heart beat and (a)(ii) a predicted future heart beat, (b) wherein the predicted heart beat time interval is based on the registered predetermined number of successive calculated heart beat time intervals, and instruct the user interface to indicate a stimulation signal to a user non-simultaneously with the predicted future heart beat at the end of the predicted heart beat time interval so as to change the heart rate and/or heart coherence of the user, wherein (i) to excite the user, the processing circuit instructs the user interface to indicate the stimulation signal just before the predicted future heart beat, and after a heart beat that occurs before an actual heart beat corresponding to the predicted future heart beat, and (ii) to relax the user, the processing circuit instructs the user interface to indicate the stimulation signal after the actual heart beat corresponding to the predicted future heart beat, and before a second future heart beat.
