Patent number: 6548980Abstract: An apparatus for driving a motor that opens and closes the window of vehicle, for example, is so adapted that when the vehicle becomes submersed in the sea, a lake or a river, etc., the window is prevented from being closed owing to malfunctioning of a relay caused when a leakage current flows into an operating switch for opening and closing the window. When submersion is sensed and it is sensed that the motor is being rotated by a malfunction in a direction that closes the window, a relay for rotating the motor in the forward direction is actuated. This prevents the occurrence of a situation in which the motor is caused to rotate (especially in the direction that closes the window) regardless of the fact that the operating switch has not been operated.Type: GrantFiled: June 15, 2001Date of Patent: April 15, 2003Assignee: Omron CorporationInventors: Yoichi Sakuma, Atsushi Kawano

The motor is normally responsive to a motor drive signal to control door/lift gate movement via rotation of the motor drive shaft. In the absence of the motor drive signal, the motor is responsive to rotation of the drive shaft, via manual movement of the door or lift gate, to produce a back electromotive force (EMF) signal at the input of the motor. The wakeup signal generating circuit is responsive to the back EMF signal to produce a wakeup signal. In one embodiment, the wakeup signal is used to cause a control circuit controlling the overall operation of the motor to wake up from a reduced-function, power conserving sleep mode of operation and operate in a full-function, full power wakeup mode of operation.Type: GrantFiled: July 27, 2000Date of Patent: June 11, 2002Inventor: John D.

Patent number: 6252363Abstract: The present invention relates to an electronic circuit that interrupts the application of electrical power to a motor after a predetermined period of time. The electronic circuit is disposed between a motor which drives a device from an initial position to a final position and a switch movable from a first position to a second position. A battery which supplies the electrical power for the motor is engaged with the switch. The control circuit includes at least two energy storage devices. Depending on the position of the switch, one of the energy storage devices will be fully charged by the battery source. Altering the position of the switch will cause the fully charged energy storage device to begin its discharge and the alternate energy storage device will be “instantly” charged. During the time that both energy storage devices have a significant charge on them, a control signal is generated.Type: GrantFiled: May 28, 1999Date of Patent: June 26, 2001Assignee: Prestolite Wire CorporationInventor: Mark Emerson Grady
