Abstract
Disclosed within is a closed loop controller having: (a) a signal processing and statistics subsystem sampling an input data stream from at least one sensor, calculating real-time continuous statistics in the input data stream based on a sliding window technique, and outputting one or more classifications based on the real-time statistics; and (b) an intelligent fuzzy logic controller receiving the one or more classifications from the signal processing and statistics subsystem, accessing a heuristic rule set based on expert knowledge, and outputting a noninvasive stimulation pattern based on the one or more classifications and the heuristic rule set.
Claims25
A closed loop controller comprising:
- a. a signal processing and statistics subsystem sampling an input data stream from at least one sensor, calculating real-time continuous statistics in the input data stream based on a sliding window technique, and outputting one or more classifications based on the real-time continuous statistics;
- and
- b. an intelligent fuzzy logic controller receiving the one or more classifications from the signal processing and statistics subsystem, accessing a heuristic rule set based on expert knowledge, and outputting a noninvasive stimulation pattern based on the one or more classifications and the heuristic rule set.

- and
- c. a synchronizer minimizing interference by coordinating timing and/or incorporating variable hardware gains that can be dynamically changed to prevent amplifier saturation between sensed signals from the at least one sensor and an applied stimulation based on the noninvasive stimulation pattern.
