Abstract: Used in an analog timepiece, a daylight saving time adjustment method is disclosed to includes the steps of: (a) use a time setting device to input date and time data and an adjustment knob to the adjust the hour and minute hands to 12:00, (b) use setting and selection buttons of the time setting device to adjust polarity relationship between stator and rotor of a driving unit for the rotor to move a gearwheel set and to further adjust the second hand to 12:00, (c) the CPU of the analog timepiece analyzes the inputted data subject to calculation of its built-in daylight saving time calculation program, and then drives the driving unit to move the hour and minute hands to indicate the local standard time subject to the inputted data if the inputted data was inputted before start of daylight saving time, or to indicate the corrected local daylight saving time if the inputted data was inputted after start of daylight saving time, and (d) CPU drives the driving unit to move the hands set, returning the analog tim

Abstract: A timepiece time having installed in the movement thereof a CPU, a time zone adjustment device and a time display unit, the CPU having installed therein a perpetual calendar program, a time zone calculation program, and a daylight saving time calculation program, the time zone adjustment device being operable to input a time zone signal to the CPU for enabling the time zone calculation program to calculate the conversion time corresponding to the set time zone and for enabling the daylight saving time calculation program to determine whether the set time zone has applied daylight saving time, such that the time display unit is controllable by the CPU to automatically adjust displayed time and to automatically enter/withdraw from the daylight saving time cycle of the corresponding time zone subject to calculation of the time zone calculation program and the daylight saving time calculation program.

Abstract: A body fat determining device takes the form of a weight measuring device, and has two pairs of electrodes, a display, and setting buttons on the upper sides. Each of the electrode pairs comes into contact with one of the subject's sole when the subject stands on the device. The electrodes of the electrode pairs can form current paths with each other, and are also provided for measuring the impedance of the subject's body such that the impedance of the contact between the subject's soles and the electrodes is eliminated from calculation. In other words, the accuracy can't be affected by unwanted factors such as moistures, roughness, or area of the subject's skin in contact with the electrodes. The device can find data that are stored in the memory, and belong to the present subject for calculation according to the datum on weight; thus, every subject only has to input data about him at the first time he uses the device.

Abstract: A device for measuring a man's body-adipose includes two pairs of electrodes. Two contacting points of the two pairs of electrodes are formed into four circuits. The resistances measured out are input in a CPU for operation and the resistances measured between fingers of two hands are eliminated by the CPU so that the resistance of one's body is not affected by different conditions of a man's fingers, dry or damp degrees, rough or smooth degrees and large or small contacting dimensions, thus, possible to get a correct body resistance and accordingly to measure out an accurate value of a man's body adipose.
