Abstract: An R-wave of a heartbeat signal accompanied by periodic fluctuation is detected to obtain the average value of an RR interval. Further, a waveform of a heart sound signal, which periodically fluctuates in synchronization with the heartbeat signal, is forcibly repositioned at an interval equivalent to the average value of the RR interval. After performing reposition, noise is removed by using orthogonal transformation and orthogonal inverse transformation, so that the position of obtained waveform is restored to its original position.

Abstract: In order to be able to accurately identify a signal source using a radio wave-type non-contact radio wave sensor without being affected by surrounding environmental vibrations, a first environmental information associated with a biological information detected by a first non-contact sensor, and a second environmental information associated with a biological information detected by a second non-contact sensor are subtracted by a first subtractor, and the signal from the first subtractor is added to a first adaptive filter and extracted as a noise source. Next, the noise source signal extracted by the adaptive filter is subtracted from the first environmental information associated with the biological information detected by the first non-contact sensor by a second subtractor, and the position of a subject is identified in accordance with the magnitude of the signal from the second subtractor.

Abstract: A device and method for detecting biological information without being affected by sudden-onset signal even when sudden-onset large vibration is caused while driving a vehicle or the like. Peak input and output values of a variable delay device are detected, and the difference between the values is determined by a subtractor. The difference is compared to a predetermined threshold to obtain a positive or negative output as an up/down selection output for an up/down counter. The output of the up/down counter is sent to a variable delay device with a clock generated based on an inputted peak signal of biological information to obtain a variable delay amount corresponding to one cycle of the biological information. When the subtractor output exceeds the predetermined threshold, a predetermined output voltage is generated, and an amplifier connected to the variable delay device is controlled so that the gain of the amplifier becomes zero.
