Time adjustment device, timekeeping device with a time adjustment device, and time adjustment method
Patent number: 9329578Abstract: A timepiece can acquire time information in a short time, reduce power consumption, and display the correct time. A timepiece comprises a receiver to receive a satellite signal, and a time information generator to generate internal time information. The receiver runs a first reception process that acquires first information including week information from the satellite signal, a second reception process that acquires second information including leap second information from the satellite signal, or a third reception process that acquires third information including hour, minute and second information from the satellite signal. In the first reception timing, after the internal time information is initialized, the receiver runs the first reception process and runs the second reception process after running the first. In a next reception timing, after the first reception timing, the receiver runs the third reception process if the first and second information are acquired in the first reception timing.Type: GrantFiled: June 4, 2014Date of Patent: May 3, 2016Assignee: Seiko Epson CorporationInventor: Norimitsu Baba -

Patent number: 9154181Abstract: A satellite signal reception device can reliably execute a satellite signal reception process. The satellite signal reception device has a reception time setting unit 71 that sets a reception time; a timekeeping unit that keeps internal time; and a scheduled reception control unit 72 that executes a time-based reception process that operates the reception unit when the time kept by the timekeeping unit reaches the reception time. By having a scheduled reception control unit 72, the reception process can be executed when the internal time goes to the reception time set by the reception time setting unit 71. The reception process is therefore executed once a day. The satellite signal reception process can therefore be executed reliably without being affected by how the device is used, the season, weather, or other factors.Type: GrantFiled: December 22, 2014Date of Patent: October 6, 2015Assignee: Seiko Epson CorporationInventors: Toshikazu Akiyama, Katsuyuki Honda, Norimitsu Baba, Jun Matsuzaki
