Abstract: An electronic watch includes a reception circuit configured to receive a radio wave, a hand, an operation device, a storage unit configured to store a reception result of whether reception by the reception circuit succeeds or fails, and a reception controller configured to switchably set a reception permission state where reception is permitted and a reception inhibition state where reception is inhibited, wherein when first operation of the operation device is performed, the hand indicates a first position in a case in which the reception permission state is set and a reception result stored in the storage unit is a success, indicates a second position in a case in which the reception permission state is set and a reception result stored in the storage unit is a failure, and indicates a third position in a case in which the reception inhibition state is set.

Abstract: The electronic watch includes a controller configured to perform switching between a time display mode which displays a time, a modification mode in which at least one of hands is moved in accordance with an operation of the operation device, and a power saving mode which consumes less power than in the time display mode by stopping at least one of the hands. The controller switches to the power saving mode when a battery voltage is detected to be less than a first voltage threshold value while the time display mode is performed, and switches to the power saving mode when the battery voltage to be less than a second voltage threshold value which is lower than the first voltage threshold value while the modification mode is performed.

Abstract: Provided is a radio-controlled timepiece that can reduce overall power consumption. The radio-controlled timepiece 1 has a receiver circuit 12 that executes during a specific time limit a reception process to acquire multiple time data from the standard time signals at different times; storage 22 that stores multiple time data; a timekeeper 23 that keeps an internal time; a time setting adjuster 24 that corrects the internal time based on coherent time data when the number of coherent time data, which is time data that is mutually coherent, in the multiple time data reaches a threshold; and a reception controller 21 that extends the time limit when the number of coherent time data is less than the threshold when a specific time that is shorter than the time limit has past since the reception process started.

Abstract: The electronic timepiece has a receiver that receives standard time signals; a detector that samples the received signal and detects the signal level; a calculator that computes, based on the detected signal level, the total signal width of a first level signal in 1-second, and the continuous time of the second level signal; and a code evaluator that determines the code transmitted in the signal based on the calculated total. The signal contains a first code and a second code in which the total signal width of the first level signal in 1 second is the same; the first code is a code that transmits the first level signal in 1 second; the second code is a code that transmits two first level signals separated by a second level signal in 1 second.

Abstract: An electrophoretic display device has an electrophoretic display panel that has a plurality of drive electrodes, a common electrode, and a plurality of electrophoretic particles disposed between the drive electrodes and the common electrode. The device also has a drive control unit including components for setting the display color and applying pulses to update the display color to a first color, a second color, or an intermediate color between the first and second colors. The first or second color is displayed by applying a first or second pulse respectively. The first and second pulses are opposite in polarity to maintain DC balance. A method of driving such a device is also provided.

Abstract: An electrophoretic display device comprises an electrophoretic display panel having drive electrodes, a common electrode, and electrophoretic particles inbetween. The panel can update the display color of each display unit correlated to a particular drive electrode according to a voltage applied between that drive electrode and the common electrode. A drive control unit applies such voltage and also has components that determine for each display unit the current display color and selectively apply specifically configured first, second and third pulses between the common and drive electrodes of display units to effect color change.
