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： There is disclosed a portable GPS (Global Positioning System) receiver carried by a user. The receiver measures the distance traveled by the user and the speed. In the prior art technique, if satellites cannot be captured, no measurements are made. To find the distance and speed accurately, the measurements have to be performed continuously, thus increasing the electric power consumed by the receiver. The inventive receiver once finds the speed from the Doppler frequencies of the carrier waves. Then, a first distance-calculating means finds the distance from the speed. A walk-detecting means detects walking. A step number-calculating means accumulates the number of steps taken in steps. A stride-calculating means finds the stride from the accumulated step number and from the found distance. Then, a second distance-calculating means finds the distance from the stride and from the accumulated number of steps. A speed-calculating means finds the speed. The GPS receiver receives at regular intervals and updates the stride.

摘要： A GPS signal receiving section measures a Doppler frequency of a carrier wave to output a three-dimensional velocity vector to a CPU 100. The CPU 100 calculates a cumulative distance from a signal receiving interval and velocity data to compare between the cumulative distance stored in a RAM 104 and the distance point data previously stored in the RAM 104. Where the cumulative distance exceeds the distance point data, a lap time is calculated and displayed on a display section 106 based on the time count data sent from the time count circuit 105. Further, the CPU 100 calculates and displays on the display section 106 a time to arrive at the predetermined moving distance from the velocity data, the cumulative distance and the predetermined moving distance stored in the RAM 104.

摘要： A pulse rate monitor having an enhanced accuracy, reduced power consumption and reduced calculation time comprises a pulse wave extraction circuitry for extracting pulse wave frequency components from a power spectrum output of a pulse wave sensor and a movement sensor, and a pulse rate calculation circuit for calculating a pulse rate in accordance with the extracted pulse wave frequency components. A display device may be included to display the calculated pulse rate. In order to reduce power consumption, unnecessary circuitry may be deactivated and unnecessary operations may be avoided by use of a changing circuit which changes the method of calculation when movement of the user is not detected. Accordingly, when no movement has been detected for a predetermined period of time, the pulse rate may be calculated based upon a direct output of the pulse rate sensor, while the frequency analysis circuitry and calculation circuitry may remain deactivated.

摘要： An improved GPS receiving apparatus may be worn on a user's arm and is not affected by the user's periodic arm swinging motion. A GPS signal receiver receives a GPS signal from GPS satellites, the receiver being mountable on a user's arm. A display is provided for displaying information based upon an output of the GPS signal receiver. An arm swing detecting circuit including an acceleration sensor detects the periodic swinging motion of the user's arm and outputs a corresponding periodic signal. A timing circuit sets a predetermined time during respective arm swing movements at which a GPS signal receiving operation will be performed based upon the periodic signal output by the arm swing detecting circuit. Operation timing of the GPS signal receiver is performed based on the output signal of the timing circuit so that a GPS signal receiving operation is performed at the same time during each cycle of periodic arm swinging motion to thereby cancel the effect of the periodic arm swinging motion.

摘要： A period and frequency measurement device is provided having a sensor for measuring pulse waves and body movements. A window determination circuit sets a reference value in accordance with previously measured pulse waves and body movements and determines whether currently measured pulse waves and body movements is within a window defined by upper and lower margins relative to the reference value. A window correction circuit corrects the window to be used for a next pulse waves and body movement measurement by applying a specified correction to the current pulse waves and body movements measurement if a determination result of the window determination circuit indicates that the current pulse waves and body movements measurement is outside a current window.

摘要： A tide meter for calculating a spring tide day. First, a moon age value is determined depending on a designated calendar. The moon age value includes at least one of the day of the new moon and the day of the full moon. Tidal data is stored that is specific for each geographic location, and this data is used in calculating the spring tide day for a selected geographic area. Since the time of the rising and falling of the tide depends on geographic location, simply calculating a spring tide day from the position of the moon and sun may not be accurate for a specific geographic location. Accordingly, the stored tidal data that corresponds to a selected geographic area is included in the spring tide day calculation. Thus, the accuracy of the spring tide day calculation is increased for the particular selected geographic area.
