Abstract: A first blood vessel diameter and a second blood vessel diameter are measured using a first ultrasonic probe and a second ultrasonic probe that are provided close to a blood vessel of a subject so as to be situated at a given distance (Lp). Characteristic phases of a pulse wave are determined from the peak of a second-order differential value of the first blood vessel diameter and the peak of a second-order differential value of the second blood vessel diameter, and the difference (?t) in pulse wave transit time is calculated from the difference in timing between the characteristic phases to calculate pulse wave velocity (PWV). A given calculation process that uses the pulse wave velocity (PWV) and the measured blood vessel diameter as variables is performed to calculate blood pressure.

Abstract: When a first half of a transmission packet is sent by an FSK modulating signal, and a latter half thereof is sent by a PSK modulating signal, a received signal is converted into an intermediate frequency signal by a mixer. The converted intermediate frequency signal is switched to an FSK demodulation unit and a PSK demodulation unit by a received signal changeover switch. A frequency error detection circuit is provided in the FSK demodulation unit to detect a frequency error detection value. A demodulation circuit of a phase locked loop type of the PSK demodulation unit includes a loop filter. The frequency error detection value detected by the frequency error detection circuit is set as an initial value of this loop filter, whereby a time until lockup of a phase locked loop is reduced at the time when reception of a PSK modulating signal is started.

Abstract: A hopping control device selects one hopping pattern out of hopping patterns P1 to PN, reads out a hopping frequency sequence arranged in the selected hopping pattern from a frequency hopping pattern memory, and sends the hopping frequency sequence to frequency synthesizers as a frequency designation signal by wire at a predetermined period. The frequency synthesizers generate local oscillation signals of a frequency specified by the frequency designation signal, respectively, and output the local oscillator signals to mixers, respectively, to thereby perform communication by a frequency hopping system between a first housing unit and a second housing unit.
