Abstract:
A heart rate detection earphone is worn on an auricle which has a cavitas conchae. The heart rate detection earphone includes an earphone body matched with and buckled in the auricle, a light guiding module disposed to the earphone body, and an optical sensor. The light guiding module defines a sensing surface exposed out of the earphone body, and the sensing surface abuts against the cavitas conchae. The optical sensor includes a light emitter and a light receiver respectively coupled with the light guiding module. Light beams emitted by the light emitter are guided by the light guiding module to irradiate the cavitas conchae. The light beams emitted by the light emitter are reflected by the cavitas conchae, and then the reflected light beams reflected by the cavitas conchae are returned to and are received by the light receiver through the light guiding module.
Abstract:
A smart watch with an ultraviolet (UV) detector includes a base body, a display module, a UV detector module and a processor module. The base body includes a top housing and a watchband. The top housing defines a receiving chamber. At least one lateral face of the top housing is an inclined face. The inclined face is recessed inward and slantwise downward to form a groove. The display module is disposed in the receiving chamber. The UV detector module is disposed in the groove and exposed outward through the groove, wherein in use, the UV detector module is located outward and upward back to a user's body for gaining UV information. The processor module is disposed in the receiving chamber and electrically connected to the display module and the UV detector module. The processor module processes the UV information and then displays processed results on the display module.
Abstract:
A vital signs measurement system includes a plurality of light sources emitting into a subject's skin. A plurality of photo sensors receives lights reflected from the subject's skin and converts the lights to a plurality of signals. A processing module receives the plurality of signals and transforms the plurality of signals to a PPG signal by analyzing a correlation coefficient between every two ones of the plurality of signals. The vital signs measurement system improves the measurement accuracy of the physiological information of the participant by the correlation coefficient.
