1. A breath monitor comprising:
- a plurality of sensors for detecting a load derived from a human lying on a bed and for outputting a sensor signal corresponding to the load; and
breath signal computation means, wherein the sensors are disposed under the human with a predetermined arrangement, and wherein the breath signal computation means converts each sensor signal to a frequency domain so that a spectrum of each sensor signal is obtained, selects the sensors on the basis of the converted sensor signals, and computes a breath signal on the basis of the sensor signals outputted from the selected sensors.

Abstract
A breath monitor includes: a plurality of sensors for detecting a load derived from a human lying on a bed and for outputting a sensor signal corresponding to the load; and breath signal computation means. The sensors are disposed under the human with a predetermined arrangement. The breath signal computation means converts each sensor signal to a frequency domain so that a spectrum of each sensor signal is obtained, selects the sensors on the basis of the converted sensor signals, and computes a breath signal on the basis of the sensor signals outputted from the selected sensors.

16. Detection equipment for detecting an apnea syndrome, comprising:
-
breath signal computation means for computing a breath signal on the basis of a change of a load, which corresponds to a body movement of breathing of a person; and
determination means for determining an apnea symptom and a hypopnea symptom of the person on the basis of a periodicity of extremums of an amplitude envelope curve of the breath signal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
