Patent number: 9784597Abstract: A voltage supply apparatus includes: a primary cell; and a constant voltage supply unit. The constant voltage supply unit has set therein a voltage drop determination value, which is a threshold that is higher than a positional-data loss level and is lower than a second output voltage, which is a constant voltage at a steady voltage level that the constant voltage supply unit outputs when in a steady state. The constant voltage supply unit converts a first output voltage of the primary cell to the second output voltage and supplies it to the absolute-position detection apparatus until the first output voltage falls below the threshold. When the first output voltage falls below the threshold, the constant voltage supply unit converts the first output voltage to a third output voltage which is a voltage at the same level as the threshold, and supplies it to the absolute-position detection apparatus.Type: GrantFiled: August 21, 2014Date of Patent: October 10, 2017Assignee: Mitsubishi Electric CorporationInventors: Akira Tanabe, Hiroyoshi Takeuchi, Yoji Tsutsumishita

Patent number: 9415737Abstract: An airbag controller in a vehicle occupant protection device deploys airbags when one of a front-right acceleration sensor and a front-left acceleration sensor disposed on a front face of a vehicle detects an over-threshold acceleration exceeding a front threshold and one of a side-right acceleration sensor or a side-left acceleration sensor, which are disposed on a side face of the vehicle, detects an over-threshold acceleration exceeding a lateral threshold. A threshold acceleration storage device stores the front threshold and plural lateral thresholds that have respectively different values. An image processor processes image data from an in-vehicle camera and calculates the offset rate, an offset direction, a collision angle, a collision direction, and a relative speed at a timing just-before an offset collision between a subject vehicle and another vehicle. Based on a detection result, the airbag controller selects one of the plural lateral thresholds stored in the storage device.Type: GrantFiled: March 11, 2015Date of Patent: August 16, 2016Assignee: DENSO CORPORATIONInventors: Yuuki Iguchi, Hiroshi Higuchi, Hisashi Takahashi, Hiroyoshi Takeuchi

Publication number: 20130289828Abstract: In an occupant protection system, a controller includes first and second comparison portions, and an activation control portion. The first comparison portion compares a first detection result from a first acceleration detection portion with a first positive threshold value and a first negative threshold value and outputs a first comparison signal when the first detection result is larger than the first positive threshold value or smaller than the first negative threshold value. The second comparison portion compares a second detection result from a second acceleration detection portion with a second positive threshold value and a second negative threshold value and outputs a second comparison signal when the second detection result is larger than the second positive threshold value or smaller than the second negative threshold value. The activation control portion activates one of side occupant protection devices based on positive or negative of the first and second detection results.Type: ApplicationFiled: April 25, 2013Publication date: October 31, 2013Applicant: Denso CorporationInventor: Hiroyoshi Takeuchi

Patent number: 7543742Abstract: A handy reader/writer has a data transmitting and receiving units and a control unit. The transmitting and receiving units communicate with a contactless IC card placed within a communication area of the communicating unit by using first electromagnetic waves outputted from an antenna. The control unit judges whether or not the card is now in communication with a second reader/writer. If the control unit detects the card communicating with the second reader/writer by using second electromagnetic waves, the control unit forbids the antenna outputting the first electromagnetic waves. If the control unit does not detect the card communicating with the second reader/writer, the control unit starts communicating with the card placed. The second reader/writer does not output the second electromagnetic waves when detecting the first electromagnetic waves, and starts communicating with the card when detecting no first electromagnetic waves.Type: GrantFiled: July 26, 2007Date of Patent: June 9, 2009Assignee: Denso Wave IncorporatedInventor: Hiroyoshi Takeuchi

Patent number: 7281599Abstract: A passenger protection system includes acceleration sensors as well as a passenger protection ECU. At least one acceleration sensor is provided on one of the width-direction sides of the vehicle and at least one accelerator sensor is provided on the other width-direction side of the vehicle. Based on signals generated by the acceleration sensors the passenger protection ECU determines occurrence of a collision, and drives passenger protection apparatus accordingly. In the event of a collision, the passenger protection ECU performs an AND operation on a signal from the acceleration sensor on the colliding one of the width-direction sides of the vehicle, and a signal from the acceleration sensor on the other width-direction side not experiencing the collision, to drive the passenger protection apparatus.Type: GrantFiled: November 9, 2004Date of Patent: October 16, 2007Assignee: Denso CorporationInventors: Hiroyoshi Takeuchi, Seiya Ide

Patent number: 6722565Abstract: A data code label including a QR code and an ID tag including a memory having an identification code area and a decode data writing area. A data code in the QR code showing an error in decoding is corrected and stored in the memory in the ID tag while the degree of defection of the QR code is low. When the defects advance, the error rate will increase. If the error occurs after advance of defects, the decode data in the memory is read when the error is detected. If the decode data cannot be read, the error correction is effected. If the error rate is higher than a reference, the decode data is obtained from the memory. If this decreases the error rate under the reference, the error correction is effected.Type: GrantFiled: February 20, 2002Date of Patent: April 20, 2004Assignee: Denso CorporationInventors: Hiroyoshi Takeuchi, Nobuyuki Teraura

Patent number: 6079619Abstract: An identification tag is attached to or imbedded in each article a plurality of which are located nearby or stacked together. The identification tag wirelessly communicates with a remote controller such as a hand-held terminal to send data or receive command. Electric power to operate the identification card is also wirelessly supplied from the remote controller. The electric power is received only by a particular identification card which is communicating with the remote controller, and is turned off when the communication is completed. The electric power is then supplied to the next identification card which communicates with the remote controller. Thus, all the identification tags sequentially send data thereof one by one to the remote controller. The remote controller includes an indicator that indicates whether the communication with all the identification tags is completed, so that the remote controller can be positioned at a right place until the end of the communication.Type: GrantFiled: July 31, 1998Date of Patent: June 27, 2000Assignee: Denso CorporationInventors: Nobuyuki Teraura, Hiroyoshi Takeuchi, Masatoshi Yamauchi
