  • Patent number: 9869977
    Abstract: A radio-controlled timepiece is shown including the following. A timekeeping unit keeps date and time. A date/time obtaining unit obtains date/time information from outside to correct the date and time of the timekeeping unit. A preliminary notice information obtaining unit obtains from outside preliminary notice information regarding whether leap second adjustment in which a leap second is inserted or deleted is executed. A date/time obtaining necessity setting unit sets whether the date/time information needs to be obtained based on history of obtaining the date/time information. The date/time obtaining necessity setting unit sets that the date/time information needs to be obtained when the preliminary notice information is not obtained by the adjustment possible date/time or the leap second adjustment is executed at the adjustment possible date/time, and does not change setting when the preliminary notice information is obtained and the leap second adjustment is not executed.

  • Patent number: 9846120
    Abstract: A light measurement apparatus includes a master laser, a slave laser, an illumination light pulse, and a signal-under-measurement generator. The master laser generates as an output a master laser light pulse, and the slave laser generates as an output a slave laser light pulse having a repetition frequency or a phase different from that of the master laser light pulse. The illumination light pulse generator receives the master laser light pulse and generates as an output an illumination light pulse, and the signal-under-measurement generator, at a point in time when receiving a light pulse under measurement obtained by illuminating the object under measurement with the illumination light pulse and further the slave laser light pulse, generates as an output a signal under measurement according to a power of the light pulse under measurement. The apparatus corrects an error in a measurement of the signal under measurement.

  • Patent number: 9709961
    Abstract: The fixed-time reception control section carries out the reception process at first time to acquire first reception time data and compares the acquired first reception time data with the internal time. When a difference in time between the first reception time data and the internal time is greater than or equal to a first threshold, the fixed-time reception control section carries out the reception process at second time different from the first time to acquire second reception time data. The time correction section compares the acquired second reception time data with the internal time and corrects the internal time based on the second reception time data when a difference in time between the second reception time data and the internal time is smaller than a second threshold.
