Radio-Controlled Timepiece And Method Of Controlling Radio-Controlled Timepiece - A simplified explanation of the abstract
This abstract first appeared for US patent application 18467183 titled 'Radio-Controlled Timepiece And Method Of Controlling Radio-Controlled Timepiece
Simplified Explanation
The patent application describes a radio-controlled timepiece that uses a second oscillating unit with a frequency less temperature-dependent than the first oscillating unit to provide temperature compensation data for the first unit.
- First oscillating unit oscillates at a first frequency and outputs a clock signal.
- Receiving unit includes a second oscillating unit that receives radio waves with time information.
- Second oscillating unit oscillates at a second frequency and outputs a clock signal.
- Control unit calculates temperature compensation data for the first unit based on the second unit's clock signal and temperature data.
- Storage unit stores the temperature compensation data for future use.

Original Abstract Submitted
A radio-controlled timepiece includes a first oscillating unit configured to oscillate at a first frequency and output a clock signal, a receiving unit including a second oscillating unit and configured to receive radio waves including time information, frequency of the second oscillating unit being less temperature-dependent than that of the first oscillating unit and the second oscillating unit being configured to oscillate at a second frequency and output a clock signal, a control unit configured to calculate temperature compensation data for the first oscillating unit based on an oscillation frequency of the first oscillating unit obtained using, as a reference, the clock signal output from the second oscillating unit and on the temperature data acquired by a temperature acquiring unit, and a storage unit configured to store the temperature compensation data. The control unit performs temperature compensation for the first oscillating unit based on the temperature compensation data and the temperature data.
