Patent number: 10043359Abstract: A monitoring area is scanned by an area sensor device (e.g., an optical distance meter) detects objects. Moving objects are identified among the detected objects, and, among the identified moving objects, a moving object which is present in the monitoring area and which has been newest identified is set as a tracking target. The moving object which has been set at the tracking target is automatically tracked by a camera device. As a result, even if there are present a plurality of moving objects in the monitoring area, tracking targets can be switched from one to another, so that it is possible to designate, as a tracking target, a moving object desired by an observer.Type: GrantFiled: March 10, 2014Date of Patent: August 7, 2018Assignees: DENSO WAVE INCORPORATED, DENSO CORPORATIONInventors: Masahiro Takiguchi, Tetsuya Iwasaki, Kenji Tsubone

Patent number: 9766056Abstract: In a monitoring apparatus, an optical sensor senses objects present in a sensing area, and moving speeds and moving directions of the objects are calculated based on changes with time in positional information of the sensed objects. An object which meets a predetermined moving condition is determined as a moving object. Hence an entrance of the moving object into the sensing area can be monitored. In this apparatus, by a determining section, it is determined whether or not an object is sensed in an area (after-passage sensing area) which is set to include positions adjacent to positions through which the sensed moving object has passed. When the object has been sensed in the area, by the determining section, it is further determined whether or not the object has remained for a predetermined determination period of time or more. This determined result is outputted by an outputting section.Type: GrantFiled: March 19, 2014Date of Patent: September 19, 2017Assignees: DENSO WAVE INCORPORATED, DENSO CORPORATIONInventors: Masahiro Takiguchi, Tetsuya Iwasaki

Patent number: 9403461Abstract: A seat heater device initiates power supply upon operation of a switch by a seat occupant within a vehicle interior and includes a heater for warming installed in a seat within the vehicle interior and a control unit for controlling energization of the heater for warming. The control unit includes a low-voltage detecting means for detecting whether an input voltage is a regular drive voltage value of the control unit or a voltage value lower than a predetermined voltage value and a switching element that is turned on when the low-voltage detecting means detects the regular drive voltage value of the control unit and turned off when the low-voltage detecting means detects a voltage value lower than the predetermined voltage value. This configuration can avoid heat generation of the switching element even if a leakage occurs in an electronic circuit within the switch due to, for example, insulation failure.Type: GrantFiled: June 8, 2011Date of Patent: August 2, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Masanori Nishikawa, Masahiro Takiguchi

Patent number: 7469127Abstract: In a noncontact information carrier reader, a receiving unit receives a response wave transmitted from a noncontact information carrier. The response wave is generated by modulating the carrier wave based on a response signal. An amplifying unit amplifies carrier wave components contained in the received response wave based on a first gain, and amplifies response signal components contained in the received response wave based on a second gain. The second gain is higher than the first gain. A synchronized-detection demodulator demodulates the response signal components contained in the response wave by mixing the transmitted carrier wave and the response wave amplified by the amplifying unit.Type: GrantFiled: September 2, 2005Date of Patent: December 23, 2008Assignee: Denso Wave IncorporatedInventor: Masahiro Takiguchi

Patent number: 6388562Abstract: A reader/writer (RW) requires identification of anti-collision techniques used by IC cards (A, B, C, and D). The IC cards implement answers to the anti-collision technique identification requirement by the reader/writer at different timings respectively for respective IC cards among the IC cards which use different anti-collision techniques respectively. The reader/writer requires identifications of types of the IC cards in dependence upon the anti-collision techniques in response to the answers by the IC cards. The IC cards return identification data thereof in response to the card type identification requirements by the reader/writer for respective IC cards among the IC cards which use different anti-collision techniques respectively. The reader/writer identifies the types of the IC cards in response to the identification data of the respective IC cards.Type: GrantFiled: January 12, 1999Date of Patent: May 14, 2002Assignees: Denso Corporation, Nippon Telegraph and Telephone Corporation, Hitachi Ltd., Tokin CorporationInventors: Masahiro Takiguchi, Kiyoshi Takahashi, Tatsuya Hirata, Shigeru Date, Hisanobu Dobashi, Shinji Nishimura, Ryouzo Yoshino, Tomoaki Ishifuji, Hiromi Sato, Toru Miura

Patent number: 6352202Abstract: A reader/writer (RW) requires identification information pieces of respective plural IC cards (A, B, C). The plural IC cards return the respective identification information pieces in response to the requirement by the reader/writer. Logical addresses are assigned to some IC cards among the plural IC cards respectively to cause the reader/writer to select them in response to the return of the identification information pieces by the plural IC cards. The IC cards selected by the reader/writer are controlled. The reader/writer cancels the assignment of the logical address to one of the selected IC cards. The logical address, the assignment of which has been canceled by the reader/writer, is assigned to an IC card among the plural IC cards to which any logical address has not been assigned yet. The IC card to which the logical address has just been assigned is controlled.Type: GrantFiled: January 12, 1999Date of Patent: March 5, 2002Assignee: Denso CorporationInventors: Masahiro Takiguchi, Kiyoshi Takahashi, Tatsuya Hirata, Shigeru Date, Hisanobu Dobashi, Shinji Nishimura, Kimiaki Ando, Tadashi Sato, Hiromi Sato, Toru Miura
