Abstract
A respiration monitoring system includes a thermoelectric generator that may be mounted within a mask enclosure or free-standing, covering all or part of the nose and/or mouth of a subject. A first temperature sensor is attached to the thermoelectric generator for measuring the subject's breath. A power controller develops a difference between a preset temperature and the subject's breath temperature that is then inserted into a feedback error signal and then into a power controller which regulates the power to the thermoelectric generator to maintain a preset temperature.

A respiration monitoring system for monitoring respiration parameters of a subject, comprising:
- (a) a first temperature sensor;
- (b) a thermoelectric generator thermally coupled to said first temperature sensor for generating an electrical signal of the subject respiration that depends on a preset temperature of said thermoelectric generator and the temperature of the subject's respiration, said thermoelectric generator to be driven to a calculated preset temperature;
- (c) a second temperature sensor to measure an ambient temperature;
- (d) a feedback error signal processor coupled to said thermoelectric generator and configured to develop and output a processed electrical signal that depends on said ambient temperature, said calculated preset temperature and said subject's respiration temperature;
- and
- (e) a compensating power controller electrically coupled to said feedback error signal processor and said thermoelectric generator for developing a compensating electrical signal input to said thermoelectric generator to drive said thermoelectric generator to said calculated preset temperature.
A method of monitoring respiration of a subject, including the steps of:
- (a) measuring a subject's respiration temperature by a first temperature sensor coupled to a thermoelectric generator;
- (b) measuring an ambient temperature by a second temperature sensor positioned to measure the ambient temperature;
- (c) calculating a thermoelectric generator preset temperature within a feedback error signal processor;
- (d) forming a processed electrical signal based upon said subject's respiration temperature and said thermoelectric preset temperature;
- (e) developing a compensating electrical signal within a compensating power controller electrically coupled to said feedback error signal processor;
- (f) applying said compensating electrical signal to said thermoelectric generator so as to drive said thermoelectric generator to said thermoelectric generator preset temperature;
- and,
- (g) repeating steps (a) through (f) throughout a plurality of breathing cycles of said subject.
