Abstract: In an electronic device provided with a resume function, a timer outputs a predetermined signal if a measured time value becomes a set time. Upon receiving the predetermined signal from the timer, a state control unit executes a resume process. A time information receiving unit receives time information that specifies a time interval, at which an application executes a predetermined process. A time interval retaining unit retains a time interval T for restoring the application to an executable state. A defining unit registers a set time with the timer on the basis of the received time information and the time interval T.

Abstract: A radio-controlled timepiece includes the following. A timekeeping unit keeps date and time. A satellite radio wave receiving unit receives a transmitting radio wave of a positioning satellite. A receiving term setting unit sets a receiving term with the satellite radio wave receiving unit. A date/time obtaining unit obtains date/time information from the transmitting radio wave received by the satellite radio wave receiving unit. An elapsed time counting unit counts elapsed time from when the date and time is obtained by the date/time obtaining unit. A first judging unit judges whether the elapsed time is less than a first reference time determined based on a timekeeping error of the timekeeping unit and a format of a signal transmitted from the positioning satellite.

Abstract: A timepiece, which includes an ornamental body; a drive mechanism that moves the ornamental body; an output portion that outputs a sound; and a control portion that performs movement control for outputting a piece of theme music and moving the ornamental body from an initial position. The control portion further performs return control for outputting a piece of ending music and moving the ornamental body to the initial position after the movement control is finished. Under the return control, the outputted and selected pieces of ending music have different lengths depending on whether or not a position of the ornamental body is in front of a reference position. It is thus possible to design the movement pattern of the ornamental body under the movement control, without consideration of the stop positions of the ornamental body at the end of the movement control period; thereby, allowing for a wide variety of appearances for the timepiece.
