  • Patent number: 6295248
    Abstract: The timing of a tide is calculated depending on a user-selected geographic region and calendar date. Tide data is stored in memory for each geographic region available for selection by the user. The timing of a tide is calculated by determining first and second tide level data using a tide level estimating equation. The first tide level data is dependent on the selected calendar date and the stored tide data that corresponds to the selected geographic region. The second tide level data having a time interval that is shorter in duration than a time interval of the first tide level is determined data again using the tide level estimating equation. The timing that a tide corresponding to the selected geographic region and calendar date occurs is then calculated dependent on the second tide level data. Thus, an accurate calculation of the timing of a desired tide is obtained for the user-selected geographic region and calendar date.

  • Patent number: 6246362
    Abstract: 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.

  • Patent number: 6226594
    Abstract: 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.

  • Patent number: 6155983
    Abstract: The present invention relates to a pulse wave detecting device for detecting pulse waves, and to a pulse measurer employing this pulse wave detecting device. The present invention addresses the problem of obtaining a pulse wave signal in which the noise components have been suitably removed from a pulse waveform, and of determining the pulse rate with high accuracy based on this pulse wave signal.The method for deriving the pulse wave signal and pulse rate is as follows.The pulse wave signal from pulse wave detecting sensor unit (30) is temporarily stored in buffer (503). When impulse noise is detected in the pulse wave signal in buffer (503) by impulse noise detecting means (505), the band pass for first digital filter (506) becomes a hill-shaped curve centered on the frequency corresponding to the preceding pulse rate, and impulse noise in the pulse wave signal output from buffer (503) is decreased.

  • Patent number: 6023662
    Abstract: In a measurement device and a measurement method for determining output values by analyzing the frequency of cyclically changing detection data, such as pulse count, the output value indicating a peak in the analysis result is corrected using side lobe values that appear on both sides of said peak, and an output value having higher precision than the output value indicating the peak value is derived, such that a value closer to the original output value of the detection data can be obtained. Because the measurement device and measurement method according to the invention can improve the precision of the output value without increasing the sampling count, highly precise output values such as pulse counts can be obtained at high speeds without extending the data fetch time.

  • Patent number: 6009375
    Abstract: 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.

  • Patent number: 5926131
    Abstract: 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.

  • Patent number: 5908396
    Abstract: In order to be able to accurately measure pitch both during running and walking, the invention focuses on the fact that the second harmonic of the body movement can be detected at a high level during running and that the third harmonic of the body movement can be detected at a high level during walking, and is designed to be able to calculate pitch regardless of whether or not the user is running or walking, by using a high-level line spectrum appearing in the area that is at or above 100 times/minute, for example, as the reference wave, and by determining whether this reference wave is the second or third harmonic. Whether the reference wave is the second or third harmonic can be determined based on whether or not a high-level signal is present near a frequency that is 1/3 or 2/3 of the frequency of the reference wave, for example; and pitch can be calculated by determining that the reference wave is the second harmonic if no high-level signal is present in the above frequency band.
