Patent number: 8848490Abstract: A reception apparatus includes a first determination unit to determine whether a state exists in which timing information and six orbital elements information can be obtained from GPS signals transmitted by only two GPS satellites. When the state exists, a calculation unit calculates a trajectory line having a predetermined width on a surface of the earth, based on the GPS signals transmitted by the two satellites. A second determination unit determines whether the trajectory line traverses a district of use stored by the apparatus. A time correcting unit obtains a current time using the obtained timing information, by correcting the timing information based on a time zone corresponding to the district of use, when the trajectory line traverses the district of use. The time correcting unit does not obtain the current time using the obtained timing information when the trajectory line does not traverse the district of use.Type: GrantFiled: December 7, 2012Date of Patent: September 30, 2014Assignee: Casio Computer Co., Ltd.Inventor: Toshio Hanabusa

Patent number: 8739226Abstract: A wireless television system includes a transmitting device that transmits by wireless transmission a digital broadcast signal obtained by receiving a digital broadcast of a plurality of channels, and a wireless television receiver. The wireless television receiver can directly receive the digital broadcast, and can receive a digital broadcast signal carried in a LAN signal transmitted by the transmitting device. The wireless television receiver compares received levels and error rates of a digital broadcast signal received directly, and digital broadcast signals of a same channel as that of the digital broadcast signal received directly. based on a result of the comparison, the wireless television receiver selects and outputs a digital broadcast signal with a highest received level or a lowest error rate from among the plurality of digital broadcast signals of the same channel.Type: GrantFiled: July 13, 2011Date of Patent: May 27, 2014Assignee: Casio Computer Co., Ltd.Inventor: Toshio Hanabusa

Publication number: 20110271305Abstract: A control data transmission and reception period of, for example, 1 ms is provided for each frame of a digital broadcast signal. The digital broadcast signal is intermittently transmitted. In the intermittent transmission, the transmitting device stops the digital broadcast signal from being sent during the control data transmission and reception period. At the same time, control data is transmitted during the control data transmission and reception period. In other words, a beacon signal is sent from a transmitting device to a wireless television receiver as control data, between the intermittent transmissions of the digital broadcast signal. Having received the beacon signal, the wireless television receiver returns a request signal to the transmitting device. As a result, communication between the transmitting device and the wireless television receiver can be established.Type: ApplicationFiled: July 13, 2011Publication date: November 3, 2011Applicant: CASIO COMPUTER CO., LTD.Inventor: Toshio HANABUSA

Patent number: 8044855Abstract: The first reception operation is started in response to an acquisition request. Power supply to a RF unit and a demodulator is stopped after synchronization with the GPS signal is established. Based on information acquired from a sub-frame in the GPS signal, a time point to start the second reception operation is determined. Elapsed time is counted using a counter clock synchronized with transmission timing of the navigation message, while a reception frequency of the satellite, a PRN code unique to the satellite, and a frequency and a phase of the PRN code are retained. When the elapsed time arrives at the time point, the power supply to the RF unit and the demodulator is restarted.Type: GrantFiled: May 28, 2009Date of Patent: October 25, 2011Assignee: Casio Computer Co., Ltd.Inventor: Toshio Hanabusa
