摘要： A pulse wave monitor having a structure capable of automatically performing optimal positioning of a pulse wave probe with respect to a user's body. A plurality of transmitting piezoelectric vibrators for transmitting an ultrasonic wave to an artery are provided along with a plurality of receiving piezoelectric vibrators for receiving an ultrasonic wave from the artery. An optimal combination of a transmitting piezoelectric vibrator and a receiving piezoelectric vibrator for use in pulse wave measurement is determined based on the intensity of a received ultrasonic wave signal. Ultrasonic wave transmission and reception are made by the optimal combination so that accurate pulse wave detection measurement is made possible by automatic positioning of the pulse wave probe.

摘要： There is provided a pulse wave detector enabling pulse wave detection with reduced power consumption, and prolonged usage time. Ultrasonic waves having a frequency of 10 MHz are transmitted from a transmitter towards an artery, and reflected waves that have undergone frequency modulation as a result of the Doppler effect of the artery are received by a receiver, pulse waves are extracted by FM detection, and a pulse rate is counted and displayed. Transmission of ultrasonic waves by the transmitter and reception of reflected waves by the receiver are carried intermittently at a frequency of 64 Hz to reduce the power consumption, to enable installation even in a small portable device with low battery capacity such as a watch, and to enable prolonged usage time. The transmitter and receiver have a rectangular shape and are arranged so that a long axis crosses the artery, which means that measurement of pulse waves can be continued without the need to correct positioning even if the artery or a sensor position shifts laterally.

摘要： In order to eliminate the unnecessary power consumption caused by the increase in frequency associated with wireless communication systems using electromagnetic induction techniques, the wireless communication system of the present invention modulates and transmits a magnetic field in accordance with information. A close-range receiver is provided with an amorphous magnetic impedance element having an impedance which varies in accordance with the modulated characteristic of the magnetic field. Use of an amorphous magnetic impedance element in the receiver results in a reduction in power and increase in sensitivity of the device.

摘要： In a pulse wave detecting device for detecting a pulse wave by use of an ultrasonic wave, in order to prevent attenuation of the ultrasonic wave caused by a gap formed between the pulse wave detecting device and the user's skin, a transmitter for generating an ultrasonic wave and a receiver are formed on a support substrate so as to protrude therefrom. Consequently, the transmitter and receiver contact a surface of the skin and no gap is formed between the surface of the skin and the pulse wave detecting device. A pulse wave detecting device high in detection accuracy is thus realized without the need for applying a gel between the skin and a detecting surface of the device.
