Patent number: 8248204Abstract: A tag detecting system for detecting a movement of a person or an object that mounts an RFID tag, a moving object detecting method, and an entrance/exit management system using the moving object detecting system are provided. The tag detecting system detects a specific person or object by restricting a detection area of the RFID tag to a narrow area. Since the moving object detecting method detects a piggyback, the entrance/exit system prevents the piggyback even if there are a number of persons passing through an entrance/exit gate almost at the same time.Type: GrantFiled: March 13, 2009Date of Patent: August 21, 2012Assignees: Hitachi, Ltd., Hitachi Engineering & Services Co., Ltd., Matrix Inc.Inventors: Masahiro Takeshima, Kazuo Tamura, Takeshi Kawahara, Masayoshi Kondou, Dai Kawarai

Patent number: 7848963Abstract: An automatic auction method which makes it unnecessary for bidders to stay before auction terminals at the time of auction and which makes possible auction transactions on an open network on which it is difficult to assure the on-line and real time properties. A plurality of auction ordering information pieces each containing a desired price, number of purchase, and a highest possible price in competition for the desired price and received from bidder terminals via on-line circuits are collected. Until an auction issue appears, the price is lowered. If there is at least one auction issue and a desired quantity which is the sum total of the numbers of purchase of the auction issues is not satisfied, then it is determined whether there is an auction issue coinciding in price by comparing the set price with (the desired price+the highest possible price in competition). Until the desired quantity is satisfied, the price is raised.Type: GrantFiled: October 9, 2009Date of Patent: December 7, 2010Assignee: Hitachi, Ltd.Inventors: Masakatsu Mori, Masahiro Ogura, Masahiro Takeshima, Kenji Arai

Patent number: 7209182Abstract: A false contour correcting apparatus is capable of removing a false contour in an image based on a digital image signal while avoiding such a side effect caused by false contour correction where noises negatively effecting the display occur on a screen. Therefore, in the false contour correcting apparatus according, a double bit change detection circuit detects as a double bit change a signal value change which is twice a minimum quantization unit in a digital image signal, and outputs a double bit change detection signal representing the position of the double bit change. A signal correction circuit corrects the double bit change in the digital image signal into two one-bit changes on the basis of the double bit change detection signal. Consequently, a false contour corresponding to a portion where the double bit change exists is removed.Type: GrantFiled: July 11, 2003Date of Patent: April 24, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Minoru Kawabata, Atsuhisa Kageyama, Masahiro Takeshima

Patent number: 6970203Abstract: The automatic cut-off system includes a video data processing circuit, a cut-off control circuit, a drive circuit, and a level control section. The video data processing circuit adds a cut-off reference pulse having a predetermined level to primary-color signals of red (R), green (G) and blue (B) at different timings within a single vertical blanking interval, and outputs latch timing signals respectively indicating the timings. The cut-off control circuit shifts a level of each primary-color signal having the cut-off reference pulse added thereto based on a corresponding cut-off control signal. The drive circuit drives each cathode of a CRT (cathode-ray tube) based on a corresponding one of the shifted primary-color signals, and outputs a voltage corresponding to each cathode current as a common feedback signal. The level control section latches the feedback signal in response to each latch timing signal, and outputs the cut-off control signal of one of the primary-color signals.Type: GrantFiled: August 22, 2002Date of Patent: November 29, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yutaka Otani, Masahiko Sasada, Nobuo Taketani, Masahiro Takeshima, Hiroshi Moribe
