Pulsation Detector

A pulsation detection system comprising,

• a beat detector for obtaining (i) a pulse wave information containing a noise generated by a body motion and (ii) a body motion information, from a living body in physical exercise movement, and
• a pulsation detector for detecting a pulsation information which is removed the noise of the body motion from the pulse wave information based on the body motion information and then outputting the detected pulsation information to an output part, and wherein
• the beat detector comprises,
• (a) a pulse wave measuring device for detecting the pulse wave information,
• (b) a body motion measuring device comprising a light source and a photodetector, wherein the light source irradiates light to a skin of a living body away from the skin so as to vary an amount of a reflected light in response to a positional change of body surface due to the body motion, and wherein the photodetector detects a reflected light from the skin, synchronizing with the pulse wave information, and then outputs a body motion information defined by the amount of the reflected light,
• (c) a transmitter for transmitting the pulse wave information and the body motion information to the pulsation detector, and
• (d) a mounting tool for mounting the pulse wave measuring device, the body motion measuring device, and the transmitter, to a surface of the living body, and wherein
• the pulsation detector comprises,
• a receiver for receiving the pulse wave information and body motion information which are transmitted by the transmitter, and
• a body motion remover for removing the noise to detect the pulsation information from the received pulse wave information and body motion information, and then outputting the pulsation information to the output port.
