Abstract:
To carry out step number measurement more precisely even when a walk signal enough to be detected is not obtained. After a fixed noise of a signal detected by an acceleration detecting portion having an acceleration sensor is removed by a filter portion of a counting portion, a walk cycle comparing portion compares a cycle of the resultant signal with a moving average value calculated by a walk cycle calculating portion, and each signal within a predetermined cycle range is counted as the number of steps for one step by a step number counting portion. A signal within a range similar to a cycle n times as large as a predetermined cycle of the signals each beyond the predetermined cycle range is judged as the number of steps for n steps by an extra-regulation step number processing portion and is counted as the number of steps for n steps by the step number counting portion. Data on the number of steps obtained through the counting in the step number counting portion is displayed on a display portion.
Abstract:
There is provided an analog radio-controlled timepiece made so as to be capable of performing a time difference correction by a simple operation while maintaining an operability of a time difference correction timepiece. A radio reception section receives, through an antenna, information of a minute and a second in a time code included in a standard radio, and an operation section corrects only a minute hand and a second hand to the minute and the second, which were received. A correction of an hour hand is performed by operating a crown included in a time difference correction mechanism.

Abstract:
To enhance precision in measurement of the number of steps even when a walk cycle changes. An acceleration detecting portion outputs a walk signal corresponding to a walk of a user detected by a walk sensor. A step number counting portion of a counting portion counts each signal which is judged to be beyond a first reference cycle range by a walk cycle comparing portion among signals from the acceleration detecting portion as the number of steps for one step, and when an extra-regulation step number processing portion judges that a predetermined number of signals each within a second reference cycle range among the signals each beyond the first reference cycle range is continuously outputted, counts the predetermined number of signals as the predetermined number of steps.
Abstract:
A portable altimeter of the present invention is provided with a movement determining unit for determining whether or not the altimeter is at a standstill or moving by comparing an amount of change in altitude with a prescribed standstill threshold value and movement threshold value. When the standstill mode is set, the moving mode is then set only when the amount of change equals or exceeds the movement threshold value, and when the moving mode is set, the standstill mode is then set only when the amount of change falls below the standstill threshold value.

In a via-human-body information transmission system, there is made so as to be capable of more stably transmitting a signal. An electrode (104) of a transmitter-receiver (102) contacting with or capacitance-connected to a human body (101) and an electrode (108) of a receiver (106) contacting with or capacitance-connected to the human body (101) are electrically connected through the human body (101) (mainly, a chest part and a left arm). An electrode (105) of the transmitter-receiver (102) contacting with or capacitance-connected to the human body (101) and an electrode (109), of the receiver (106), having been disposed while being directed to an outside of the human body (101) are electrically connected by a capacitance connection. A communication between the transmitter-receiver (102) and the receiver (106) is performed through a path passing the electrodes (104, 105, 108, 109) and the human body (101) and a path by the capacitance connection.

Abstract:
A portable pressure measuring apparatus detects a designated altitude by sensing an outside atmospheric pressure. An A/D converter generates pressure data corresponding to the outside pressure. Pressure data corresponding to a designated altitude is stored in a memory, and the pressure data generated by the A/D converter is compared with the stored pressure data. The designated altitude may be set to any value through a manually-operated input switch and converted into pressure data. Alternatively, the designated altitude may be set as the altitude at which the apparatus is positioned by converting pressure data generated by the A/D converter at that altitude into a corresponding altitude.
Abstract:
It is an object of the present invention to provide a portable pressure measuring apparatus to be used as an altimeter, which can be automatically switched to an optimum sampling period in accordance with a use of the apparatus before a pressure measurement at all times. A portable pressure measuring apparatus additionally comprises a pressure/altitude operation section for obtaining an altitude from a measured pressure by an arithmetic operation, a rate of pressure change operation section, and a movement detecting section, wherein, if the movement detecting section detects a movement, a pressure is measured in a sampling period, for example, in a 1-second sampling period, if a rate of altitude change is equal to or greater than a threshold or in a sampling period, for example, in a 5-second sampling period, if the rate of altitude change is smaller than the threshold and wherein, unless the movement detecting section detects any movement, the pressure sampling measurement is not performed.
