Abstract:
A portable electronic device includes: a wireless communication unit that transmits and receives data to and from an external device via near field communication; a measuring unit that measures a physical quantity for determining a predetermined kinetic state of the portable electronic device; an announcement unit that issues a predetermined announcement; an announcement setting unit that makes a setting for whether to permit the announcement and/or for an announcement mode based on the kinetic state of the portable electronic device, which is determined based on the measurement by the measuring unit, and the kinetic state of the external device, which is acquired via the wireless communication unit; and an announcement controller that controls the announcement unit to issue the announcement based on the setting made by the announcement setting unit.
Abstract:
A radio wave receiver includes a radio wave reception processor which receives radio waves and obtains signals transmitted from positioning satellites from the received radio waves; and a processor which sets reception start timing of the radio waves by the radio wave reception processor and controls the radio wave reception processor to start reception. The processor sets the reception start timing so that following reception conditions are satisfied: (i) a total power consumption amount of a power amount necessary for positioning and a power amount according to an obtaining upper limit time from start timing of a positioning operation by the radio wave reception processor to when the radio wave reception processor obtains signals necessary for computing a present position and the positioning operation is equal to or less than a predetermined upper limit power consumption amount, and (ii) the obtaining upper limit time is equal to or more than a predetermined reference time.
Abstract:
A portable display device includes: an acceleration sensor; an outputting section outputting a detection signal when a measurement value changes across a reference value; a calculating section calculating a duration time in which the measurement value exceeds the reference value; a judging section judging whether the movement state is due to running based on an occurrence frequency of the movement state and the duration time; a setting section setting a running state when the movement state is due to the running; a calculating section calculating a time interval between the movement states; a continuous tap judging section judging whether the movement states are due to continuous tap operations according to a judgment condition based on the duration time and time interval; and a setting range changing section setting a range of the judgment condition in the running state to be broader than that in a non-running state.
Abstract:
A radio wave receiver, that receives satellite waves, includes a GPS reception processing unit configured to receive signals from a plurality of positioning satellites, acquire data necessary for positioning from the received signals, calculate a current location of the radio wave receiver, save a failure history related to acquisition of the data necessary for positioning with respect to each of the received signals, determine a reception condition of each of the received signals in accordance with the failure history, and suspend acquisition of the data necessary for positioning with respect to a signal having the reception condition determined to be at least equal to a predetermined reference level, the signal being among the signals from the plurality of positioning satellites.
Abstract:
An electronic device includes a clocking unit; a receiving unit; a reception control unit; and a date and time obtaining unit. The reception control unit makes the receiving unit receive first date and time information which is transmitted from a positioning satellite, the first date and time information indicating an elapsed time from a start of a week to an end of the week, and the reception control unit does not make the receiving unit receive second date and time information which is transmitted from the positioning satellite, the second date and time information indicating a week number. The date and time obtaining unit calculates an uncorrected date and time based on the first date and time information and a clocking unit week number which is a week number calculated from date and time counted by the clocking unit.
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.
