Publication number: 20030189558Abstract: With the aim of offering a video display technique by which stable and high contrast video images are reproduced, contrast adjusting circuitry is constructed. The contrast adjusting circuitry detects a maximum picture level (MPL) and an average picture level (APL) of analog-to-digital converted luminance signals for a predetermined period, determines one of the predefined luminance regions within which the MPL falls and one of the predefined luminance regions within which the APL falls, and, based on the thus determined luminance regions of both MPL and APL, carries out a contrast adjustment of video images by changing the gain of luminance signals and color depth correction by changing the gain of color signals.Type: ApplicationFiled: November 15, 2002Publication date: October 9, 2003Inventors: Hiroshi Aoki, Ryo Hasegawa, Takaaki Matono

Patent number: 6626460Abstract: A method of suitably controlling an airbag device or a pretensioner without imposing a burden on an airbag deployment control system and without complicating the wiring and logic for information interchange. A load discriminator receives an output from seat load cells and binarizes the output of the seat load cells, i.e. the weight of an occupant, with reference to two different threshold values corresponding to ON and OFF of the buckle switch, thereby obtaining two results. The weight discriminator sends the respective results to an airbag controller. The airbag controller receives the results and an ON/OFF signal from the buckle switch, employs the result according to the threshold value corresponding to the actual ON/OFF state of the buckle switch, and judges the kind (adult or child) of the occupant based on the employed result. Then, the airbag controller judges the actuation of the airbag based on this discrimination.Type: GrantFiled: June 14, 2001Date of Patent: September 30, 2003Assignee: Takata CorporationInventor: Hiroshi Aoki

Patent number: 6574540Abstract: A vehicle collision damage reduction system is provided. The system works by detecting the relative speed between the vehicle and an object, such as another vehicle. A danger level is calculated based on parameters such as speed and distance to the object; the danger level could be at an “emergency level” or at some lower level. Based on the danger level, different corrective measures and the degree of the corrective measures can be adjusted to attempt to minimize occupant injury. For example, the airbag can be adjusted to better protect the occupant, a pre-tensioner can be activated at a certain level, and the inclination of a child restraint seat may be adjusted as well.Type: GrantFiled: July 8, 2002Date of Patent: June 3, 2003Assignee: Takata CorporationInventors: Keishi Yokota, Hiroaki Fujii, Tadayuki Ato, Eiji Yanagi, Hiroshi Aoki

Patent number: 6571647Abstract: In order to provide a seat weight measuring apparatus in which the performance of load sensors is not spoiled due to dimensional error or deformation of a vehicle body or a seat and provides higher precision measurement, a seat weight measuring apparatus is provided for measuring a seat weight including the weight of a passenger sitting thereon and comprises load sensors for converting at least parts of the seat weight into electric signals and a dislocation/deflection absorbing mechanism (pin brackets and pins) arranged between a seat and the load sensors. Each load sensor comprises a cantilever-type sensor plate which is deformable when subjected to load, and a plurality of strain gauges attached to one surface (strain measuring surface) of the sensor plate. The load sensor is so structured that one of the strain gauges is subjected to tensile strain while the other one of the strain gauges is subjected to the compressive strain when the sensor plate is subjected to the applied load and is thus deformed.Type: GrantFiled: March 9, 2000Date of Patent: June 3, 2003Assignee: Takata CorporationInventors: Hiroshi Aoki, Shuji Kusaka

Patent number: 6546817Abstract: To provide a diagnostic method of a seat load measuring apparatus for detecting an abnormality of the seat load measuring apparatus, outputs of load sensors 1R, 1L are inputted into a differential amplifier 4 through a multiplexer 3, converted into digital signals by a A/D converter 5, and then inputted into the MPU 6. An offset correction amount is added into the input of the differential amplifier 3 from the MPU 6 through a D/A converter 10. First, the output of the differential amplifier 4 is measured in a state in which no load is applied to a seat and a value thus measured is assumed as X1. After a predetermined load is applied to the seat, the output of the differential amplifier 4 is measured and a value thus measured is assumed as Y1. It is judged that a difference between X1 and Y1 is in a predetermined range between A1 and B1. When the difference between X1 and Y1 is not in the range between A1 and B1, an alarm indicating abnormality is emitted.Type: GrantFiled: February 8, 2000Date of Patent: April 15, 2003Assignee: Takata CorporationInventor: Hiroshi Aoki
