1. A system comprising:
- a sensor device sensitive to temporal variations of flux of infrared (IR) radiation emitted by a human body, said variations measured relatively to a predefined reference flux of said radiation, said reference flux is the IR flux, emitted at a body'"'"'s thermal comfort state;
a transmitter device coupled to said sensor device and producing a signal fora receiver device, capable of displaying said variations of said flux of said radiation.

Abstract
Systems and methods for monitoring baby'"'"'s or partially disabled patient'"'"'s level of thermal comfort during his/her rest in bed are provided. Preferably, the system comprises: a sensor of infrared (IR) radiation coupled to electric circuitry, the circuitry includes a transmitter of radio signal, and, as a separate unit, a receiver of this radio signal. The transmitter includes a circuit containing an alarm with an adjustable threshold that turns the alarm on whenever the heat flux radiated by the body of a patient or a baby rises above user-adjustable upper threshold value, or falls below lower threshold value. The system may be combined with a standard, advanced or video baby monitor.

10. A method of monitoring a human employing a parent unit and a baby unit, said baby unit including an infrared sensor device coupled to transmitting electric circuit, said parent unit including receiving electric current, said method comprising the steps of:
-
installing and configuring the system; receiving the infrared flux emitted by said human said infrared sensor device; converting said flux into an electric signal by said transmitting electric circuit; processing of said electric signal by said transmitting electric circuit;
said processing comprising;comparing said electric signal to a signal corresponding to a flux emitted by said human in a state of thermal comfort; sending the result of said comparison to said receiving electric circuit; and
activating said parent unit. - View Dependent Claims (11, 12, 13, 14, 15)
