Abstract: A physical condition change detection device for detecting a change in physical condition of a subject includes a body-surface-side biological information detection unit that is configured to detect a variation in biological information obtained from a body surface of the subject and that is to face the body surface of the subject and an outside thermal variation detection unit that faces away from the body-surface-side biological information detection unit and that is configured to detect a thermal variation in an outside area separated from the body surface of the subject. The physical condition change detection device further includes a transmit unit configured to provide control to transmit detection data of the body-surface-side biological information detection unit and the outside thermal variation detection unit to the outside at every given time.

Abstract: A non-contact blood vessel analyzer includes an image acquisition device and an image processing device. The image acquisition device acquires an image which is a moving image or successive still images of a blood vessel. The image processing device detects a beat and a thrill from temporal change of an index derived from brightness and/or chromaticity of the image.

Abstract: Disclosed is a pulsation detection system for obtaining the accurate pulsation information by removing a noise of a body motion. The system includes a beat detector obtaining a pulse wave information containing a body movement noise and a body motion information, and a pulsation detector outputting a pulsation information after the noise of the body motion is removed from the pulse wave information. The beat detector includes a pulse wave measuring device, and a body motion measuring device having a light source for irradiating light to a skin and a photodetector for detecting a reflected light from the skin, arranged at a position away from the skin. The pulsation detector includes a receiver for receiving the pulse wave information and the body motion information, and a body motion remover for removing the noise so as to output an accurate pulsation information to the output part.

Abstract: Disclosed is a pulsation detection system 1 for obtaining the accurate pulsation information of which a noise of a body motion is removed. The system 1 comprises a beat detector 3 obtaining a pulse wave information and body motion information containing a body movement noise, and a pulsation detector 4 outputting a pulsation information of which the noise of the body motion is removed from pulse wave information. The beat detector 3 comprises a pulse wave measuring device 31, and a body motion measuring device 32 comprising a light source irradiating and a photodetector for detecting a reflected light from the skin, arranged at a position away from the skin. The pulsation detector 4 comprises a receiver 44 for receiving the pulse wave information and the body motion information, and a body motion remover 45 removing the noise so as to output an accurate pulsation information to the output part.
