Motoatsu Yoshikawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Wireless tag, wireless tag communication system, wireless tag access device, method of detecting corresponding wireless tags and computer readable medium
    Patent number: 8334752
    Abstract: A wireless tag includes at least one of a signal radiation unit that radiates a first linking signal based on an instruction from a wireless tag access device, and a signal detection unit that detects a second linking signal that has been radiated and provides the second linking signal to the wireless tag access device.
    Type: Grant
    Filed: June 6, 2008
    Date of Patent: December 18, 2012
    Assignees: Oki Electric Industry Co., Ltd., Oki Consulting Solutions Co., Ltd.
    Inventors: Shigezou Kukita, Takahide Kawakami, Koichi Sakanashi, Fujio Deguchi, Masayuki Muratani, Masaru Nishijima, Motoatsu Yoshikawa, Shirou Nagata
  • Frame synchronous control for use in a DSRC system using operational information provided from input circuitry of an on-board unit
    Patent number: 7787579
    Abstract: A frame synchronous circuit operable in a dedicated short-range communication system, applicable to several modulation schemes, includes a UW detector for detecting a UW word from received data, an operation setting register group for specifying the operations of an on-board unit, a synchronous manager for controlling synchronization, an unlimited synchronization continuation register for maintaining the unlimited continuation of the synchronization, and an FCMC data analyzer for analyzing FCMC data. The operation setting register group can control synchronization by using not only operational information obtained from the FCMC data but also another operational information retrieved from an input device such as a CPU or terminal connected to the on-board unit. Consequently, debug and test operations can be performed without receiving any FCMC data.
