20100315907Electronic Device And Control Method Therefor - An electronic device that receives a radio signal according to specific conditions and displays specific information, including a reception unit that receives the radio signal; an electrophoretic display unit that displays the specific information; a display drive unit that supplies a drive signal corresponding to content of the specific information to be displayed to the electrophoretic display unit; and a control unit that instructs the reception unit to receive the radio signal and instructs the display drive unit to supply the drive signal to the electrophoretic display unit, instructs the display drive unit to supply a drive signal for displaying an indication that the reception unit is receiving the radio signal to the electrophoretic display unit before instructing the reception unit to receive the radio signal, and controls the display drive unit to stop supplying the drive signal while the reception unit is receiving the radio signal.12-16-2010
20130121117LEAP SECOND AND DAYLIGHT SAVING TIME CORRECTION FOR USE IN A RADIO CONTROLLED CLOCK RECEIVER - A novel and useful system and method for leap second and daylight saving time (DST) correction for use in a radio controlled clock (RCC) receiver. The RCC receiver extracts schedule information from the frame, including the time for the DST transition and whether a leap second needs to be added at the end of this half-year. Linear error correcting coding is used for the leap second and the DST on/off indications, while non-linear error correcting coding (e.g., a look up table) is used for the DST schedule to enhance reception reliability in the presence of noise and interference. The one second/one hour corrections are scheduled to occur when they should take place and the correction is applied exactly when DST or leap second is to go into effect, without having to receive anything around the time of the correction.05-16-2013
20120020191Wireless Clock System - A wireless system and method comprises a plurality of master time sources, each master time source wireless transmitting time signals containing time data, a plurality of slave clocks, each of the slave clocks for wirelessly receiving time signals which cause the slave clocks to operate in synchronization with a source of the received time signals, the source of the received time signals for at least one of the slave clocks being the master time source and the source for each other one of the slave clocks being one of the master time source or another one of the slave clocks which receives and retransmits the time signals in repeater fashion; and wherein each of the slave clocks is associated and paired with the master time source from which the time signal is first transmitted.01-26-2012
20130208573PIEZOELECTRIC VIBRATING PIECE, PIEZOELECTRIC VIBRATOR, OSCILLATOR, ELECTRONIC DEVICE, AND RADIO-CONTROLLED TIMEPIECE - Provided are a piezoelectric vibrating piece, a piezoelectric vibrator, an oscillator, an electronic device, and a radio-controlled timepiece which can effectively suppress the vibration leakage while maintaining sufficient rigidity of the piezoelectric vibrating piece without making the piezoelectric vibrating piece large-sized. A chamfered portion is formed on corner portions of a connecting portion 08-15-2013
