Patent number: 7898195Abstract: The present invention presents a motor drive device capable of detecting jamming accurately without falsely detecting jamming when a movable part contacts with other members. Jamming by a backrest is detected by judging whether the value of a period of one pulse P1 and a period of the next pulse P2 (P2/P1) integrated for 150 times (integrated value: 150) exceeds a specified threshold (160) or not. Accordingly, if the backrest rubs against a backrest of an adjacent seat, and the motor speed suddenly drops for a short period, such “warp” is not falsely detected as jamming, and only actual jamming can be detected securely.Type: GrantFiled: November 27, 2007Date of Patent: March 1, 2011Assignees: Kabushiki Kaisha Imasen Denki Seisakusho, NHK Spring Co., LtdInventors: Toshiaki Sone, Akira Sakoguchi, Hiroyuki Ueki, Takeshi Nakamura, Akira Sasaki

Patent number: 7859204Abstract: A controller prestores average moving speed data, which corresponds to respective corresponding positions of a window glass of a door driven by a motor at the time of the closing movement of the window glass, as learning data. The controller senses pinching of an object by the window glass based on the learning data and the speed measurement signal obtained at the time of the closing movement of the window glass. The controller senses a disturbance when the speed measurement signal obtained at the time of the closing movement of the window glass exceeds a predetermined value. The controller updates the learning data based on the average moving speed data at the time of the closing movement of the window glass. The controller controls execution and non-execution of updating of the learning data in response to a close state and an open state of the door.Type: GrantFiled: May 27, 2008Date of Patent: December 28, 2010Assignee: Asmo Co., Ltd.Inventors: Shin Sakai, Takahiro Sumiya

Patent number: 7750588Abstract: A method of accurately maintaining, in position registers of memory modules, a net count of rotor signals received from a motor equipped with a rotor position sensor. A vehicle apparatus includes the memory modules and motor, as well as a driven component and processors that: (a) adjust the net count while the motor is driven; (b) monitor for, and terminate power upon encounter of, a mechanical stop; and (c) correct the net count for rotor signals received thereafter. Storage media and memory modules are encoded with processor instructions and processor-readable code that, when executed by processors, cause them to perform the method.Type: GrantFiled: June 29, 2007Date of Patent: July 6, 2010Assignee: Faurecia Automotive Seating Canada LimitedInventor: Xuyang Zhang

Patent number: 7741801Abstract: The invention provides a device for automatically opening and closing a lid of a trash bin in noncontact fashion disposed in a lavatory unit of an aircraft. On the upper portion of a trash bin 100 disposed in a lavatory unit of an aircraft is attached a lid 50 that pivots via a shaft 250. The reflective infrared radiation sensor 200 attached to a lid frame 60 irradiates infrared radiation IR and detects an object. When the object is detected, a control means drives the DC motor 220 to pivot the shaft 250 via a rotating lever 240 and link arms 242 and 244 to open the lid 50 downward. The fully closed state and the fully opened state of the lid 50 can be detected by position detecting sensors 260 and 262.Type: GrantFiled: December 14, 2004Date of Patent: June 22, 2010Assignee: Jamco CorporationInventor: Masahito Fukuizumi

Patent number: 7701157Abstract: A motor controller for fully closing and opening a window glass for a vehicle door. The motor controller controls a motor that drives the window glass and includes a relay circuit connected to the motor and switching contact states in accordance with movement of the window glass. An FET is connected to the relay circuit. A sensor detects rotation speed of the motor and generates a detection signal. A CPU, which is connected to the FET and sensor, generates a duty signal having a duty ratio that is in accordance with a waveform of the detection signal generated by the sensor, provides the FET with the duty signal, and drives the motor in accordance with the waveform of the detection signal.Type: GrantFiled: March 22, 2007Date of Patent: April 20, 2010Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Yasuhiro Shimomura, Hirofumi Moriya

Patent number: 7583040Abstract: An operating device for an overhead closure which comprises a motor, operatively connected to the closure for opening and closing the closure, and at least one sensor unit mountable either the closure or a support surface bordering the closure. The sensor unit is operable to detect the presence of an obstacle obstructing a travel path of the closure and to generate a signal in response thereto. A control system is in communication with the sensor and with the motor. The control system includes a control unit which receives the signal and provides a sensing feature which stops and/or opens the closure in response to the signal. The control unit deactivates the sensing feature at a selected point prior to an end limit position of the closure. The selected point is determined by the control unit based on a calculated delay characteristic.Type: GrantFiled: September 29, 2006Date of Patent: September 1, 2009Assignee: 9141-0720 Quebec Inc.Inventors: Christian Claudel, ChangLu Wang

Patent number: 7526371Abstract: The present invention concerns a method for the position-dependent control of a mobile element in a motor vehicle, wherein the element is movable in a drive movement by an electrically powered positioning device, wherein the positioning device has several different operational modes, and characteristics of a drive signal of the positing device, in particular a waviness of a drive current, are used for the determination of the position of the element. According to the invention, a characteristic variable, which influences the drive movement of the positioning device, and/or a specific value, which characterizes the positioning device, are evaluated for the determination of an error value of the determined position of the mobile element, and that the operating modes of the positioning device are controlled in dependence of the determined error value.Type: GrantFiled: June 10, 2005Date of Patent: April 28, 2009Assignees: Brose Fahrzeugteile GmbH & Co., Kommanditgesellschaft, HallstadtInventors: Jürgen Seeberger, Carsten Abert
