Patent number: 7589685Abstract: To provide a compact and low-cost glass antenna in which an antenna position can be easily recognized by emitting a light near the antenna position, and thus a passerby or the like can easily grasp the position when he or she holds up a tag. The glass antenna has plate-like glasses 11A and 11B, antennas 12A and 12B provided on the plate-like glasses 11A and 11B, and a light emitting unit 16a that is provided so as at least a part thereof to be overlapped with the antennas as seen from the direction that the antennas 12A and 12B are directed, and scatters the light guided by the plate-like glasses 11A and 11B to emit light in the vicinity of the antenna.Type: GrantFiled: January 17, 2006Date of Patent: September 15, 2009Assignees: Fujitsu Limited, Fujitsu Frontech Limited, Nippon Sheet Glass Co., LtdInventors: Toshiaki Ibi, Shigeru Hashimoto, Toru Maniwa, Akihide Sano

Publication number: 20020060498Abstract: The memory backup device obtains power from four power supply systems having different voltages. These power supply systems are selectively employed based on their voltages. In operating, backup is performed by an internal battery as a first power supply system, or by power from a mainframe apparatus as a third or fourth power supply system. When the electronic device is to be stocked in a warehouse, only then, an external battery is connected as a second power supply system.Type: ApplicationFiled: March 5, 2001Publication date: May 23, 2002Inventors: Yasuyuki Higashiura, Takumi Kishino, Toshiaki Ibi, Takashi Ono, Shoki Kadowaki

Publication number: 20010014944Abstract: There is provided a data communication device for transmitting input data to a host device, comprising: a sampling unit for sampling the input signal corresponding to the input operation at every prescribed timing cycle; a transmitter for transmitting data corresponding to the level of the sampled input signal to a host device; and a dummy signal generator for generating a dummy signal and laying the dummy signal over the input signal during the time period other than the sampling period. Even in the case of wiretapping of the input signal, the dummy signal that is unrelated to the input operation will thereby be detected along with the input signal. Theft of the data corresponding to the input signal can be prevented because the wiretapper will be unable to distinguish which is the input signal.Type: ApplicationFiled: March 27, 2001Publication date: August 16, 2001Applicant: FUJITSU LIMITEDInventors: Toshiaki Ibi, Takumi Kishino, Shigeru Hashimoto, Koken Yamamoto
