    Abstract: When recovering power from a motor driver, a forward voltage across a parasitic diode can reduce the recovery efficiency, and control of a power recovery operation can take an unnecessarily long time. In order to address this problem, the power recovery operation is performed as follows without being affected by a parasitic diode: near a peak position of a waveform of an induced current resulting from free oscillation of a rotor after a drive pulse is output, a recovery pulse having such a level that the rotor does not rotate is output from a terminal different from a motor driver terminal to which the drive pulse was output. Also, by adjusting the width and output timing of the recovery pulse based on a power supply voltage, the power recovery can be optimized for the power supply voltage.

  • Patent number: 8274863
    Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the battery reliability service life time from being exceeded even when the period of time that the chronograph function is used is short, making it possible to prevent failure generation in the chronograph timepiece due to liquid leakage. A 24-hour counter down-counts a period of time that has elapsed starting from 24 hours, and a chronograph counter down-counts the period of time that chronograph measurement operation is performed from a predetermined time; when the count values of the 24-hour counter and the chronograph counter become equal to each other, a processing unit consumes a battery for the residual period of time of the two counters by a battery power consuming unit.

  • Patent number: 8258964
    Abstract: A recording unit includes one or more signal sensors and a recording controller. The recording controller is configured to execute a first recording instruction to record first data received from the one or more signal sensors. The first data is recorded according to first recording rules that specify a first value of a parameter. The recording controller is also configured to, in response to an irregularity detected in the first data, execute a second recording instruction to record second data received from the one or more signal sensors. The second data is recorded according to second recording rules that specify a second value of the parameter, where the second value differs from the first value.
