103 results about "Quartz clock" patented technology

A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds.

The invention relates to a control method of a pointer type CDMA quartz clock, and belongs to the technical field of clock production and processing. According to the control method of the pointer type CDMA quartz clock provided by the invention, the pointer type clock is mainly subjected to timing by taking a precise satellite time provided by a CDMA mobile phone network signal which is wide in signal coverage and great in signal intensity as a standard time by virtue of a CDMA circuit module. The method does not severely require the geographic position of the quartz clock as that of a radio controlled clock. The position is random. Even if the clock is mounted in a building, the CDMA signal is also powerful, so that the defect that the radio controlled clock cannot receive weak signals or mistakenly decodes the signals is avoided effectively. Moreover, a receiving antenna is built in the quartz clock like that of a mobile phone, so that the clock is very easy to mount and suitable for various occasions such as domestic use and office.
