摘要:
A time adjustment device having a time information generating unit that produces time information and outputs the generated time information; a reception unit that receives satellite signals transmitted sequentially from a positioning information satellite in subframe information units where a plurality of subframe information units each containing satellite-time-related information and at least one subframe information unit containing satellite health information is a unit, the satellite-time-related information is the time-related information of the positioning information satellite, and the satellite health information denotes an operating condition of the positioning information satellite; an external input unit that outputs command information instructing the reception unit to receive in response to external input; a reception timing configuration unit that sets the start time of reception by the reception unit so that the satellite signal is received immediately or at a predetermined timing based on command information from the external input unit; and a time adjustment information storage unit that stores the satellite-time-related information of the satellite signal received by the reception unit as time adjustment information. The generated time information is corrected based on the time adjustment information, and reception by the reception unit starts when the start timing comes.

摘要:
A time correction device has a reception unit that receives satellite signals transmitted from positioning information satellites orbiting the Earth; a time correction information storage unit that stores time correction information for correcting time information produced by a time information generating unit; and a time information correction unit for correcting the time information based on the time correction information. The satellite signals are transmitted by individual positioning information satellites, and contain a time-related information part denoting time-related information that is kept by each satellite, and a satellite information part denoting satellite information other than the time-related information. The time correction information is generated based on the time-related information. The reception unit receives the satellite signal during the signal period in which the time-related information part can be received, and does not receive the satellite signal during the signal period in which the satellite information part can be received.

A radio-controlled timepiece can adjust the time with a short reception process while also reducing the likelihood of incorrect adjustment. The radio-controlled timepiece has a reception control means 31, time information updating means 32, time adjustment storage means 33, and time display means. The reception control means 31 has a simple time adjustment means 330 that is driven within a predetermined time of the last successful signal reception, and a normal time adjustment means 320 that is driven when this predetermined time has passed. The simple time adjustment means 330 has a pulse timing detection unit 331, a offset calculation unit 332, a offset evaluation unit 333, and a seconds information adjustment unit 334. The pulse timing detection unit 331 detects the reference timing, which is the timing of the rising edge or falling edge of rectangular wave pulses in the received time code. The offset calculation unit 332 calculates the difference between this reference timing and the timing of the seconds unit in the internally kept time. The offset evaluation unit 333 determines if this offset is within a tolerance range. The seconds information adjustment unit 334 adjusts the seconds unit of the internal time based on the offset if the offset is within the tolerance range.
摘要:
A radio-controlled timepiece with an internal antenna provides an improved arrangement within and appearance to a case member of the timepiece that reduces manufacturing cost and affords a smaller timepiece. The antenna, which has a core and coil wound around the core, is rendered inside the case member such that both end portions of the core, and preferably the entire core, are disposed along a curved inside surface of the case member. Because the end surfaces of the core do not oppose the inside surface, the antenna can be located close to the case member without a drop in antenna performance. The case member can therefore be made of metal to give the timepiece a better design and appearance. With such an arrangement, production cost can be reduced because notches need not be formed in the case, and the timepiece can be made smaller.

摘要:
A user can easily identify the content of data (the value or the state of the data), such as a credit balance, stored in a contactless IC module provided in a wrist-watch device having a communication function. A timepiece control unit 14 of a timepiece module 10 transmits a confirmation command for the data, such as the credit balance, to a contactless IC module 60 every determination cycle period TSP, and receives the data stored in the contactless IC module 60. When the value of the stored data (for example, the amount of balance) becomes smaller than a predetermined value, the timepiece control unit 14 causes a second hand to perform an irregular movement noticeably different from the regular timing movement. Accordingly, the user is able to easily identify the data content (for example, insufficient balance).

A hand-held electronic device comprises an IC-card chip unit, a watch CPU, a power source unit, a display unit, and a switch connected between the power source unit and the IC-card chip unit. The watch CPU has a power supply controlling unit. The IC-card chip unit performs contactless data communication with an external transmitter-receiver in close range. The watch CPU operates on power from the power source unit, receives data from the IC-card chip unit to display the data on the display unit or to process the data before displaying them on the display unit. The power supply controlling unit closes a switch at least during the period of time that the watch CPU receives data from the IC-card chip unit, thereby causing power to be supplied from the power source unit to the IC-card chip unit.

A mobile telephone device effects the image and voice communication with the other party of communication through a network. The mobile telephone device transmits the voice received from the other party, to a headset having a voice input/output unit by local radio communication, and receives by local radio communication and transmits to the other party the voice received from the headset. Also, the mobile telephone device transmits the image received from the other party to a wearable radio communication device having an imaging unit and a display unit by local radio communication, and receives by local radio communication and transmits to the other party the image from the wearable radio communication device. The wearable radio communication device receives an image from the mobile telephone device by local radio communication and displays it on the display unit, and picks up an image by the imaging unit and transmits it to the mobile telephone device by local radio communication. The headset receives the voice from the mobile telephone device by local radio communication and outputs it from the voice input/output unit while at the same time transmitting the voice input through the voice input/output unit, to the mobile telephone device by local radio communication.
