The microcontroller is operable to store door mid-stop time delay values, braking rates, a door position limit overrun signal, a door cycle count, door reversals upon receiving an obstruction detector signal and error codes associated with door operator and control system malfunctions. The brake may be controlled on a variable duty cycle to provide smooth braking action in both directions of movement of the door.Type: GrantFiled: December 13, 2001Date of Patent: May 18, 2004Assignee: Overhead Door CorporationInventors: Brett A. Reed, Robert E. Balli

Patent number: 6724164Abstract: A power-window control device is provided which is capable of inexpensively avoiding the occurrence of a failure, not to overlook in safety, due to a short-circuit (including current leak) at between adjacent ones of switch terminals. The switch terminals are arranged in a combination that the terminals having a possibility to cause a failure due to short-circuit are not in an adjacent relationship. Specifically, in the case of a configuration of FIG. 1, arrangement is made such that there is no adjacent relationship between the MU and the COMA, the MD and the COMA, the NC and the COMA, the NC and the NO, the NC and the COMS, the NO and the COMA, the NO and the COMS, and the COMA and the COMS, e.g. in an order of the COMS, MD, NO, AD, COMA, AU, NC and MU.Type: GrantFiled: June 18, 2003Date of Patent: April 20, 2004Assignee: Omron CorporationInventors: Keiichi Shimizu, Yasuhide Tanaka

Patent number: 6703804Abstract: The invention concerns a method for controlling a motor vehicle wiper motor comprising steps which consist in: determining at least a range related to an operating parameter of the motor and capable of having several non null values; comparing said range with a predetermined threshold (high LS, low; HS, high INT, low LS, low INT); and controlling the motor on the basis of the result of the comparison. The range is determined when the rotor of the motor occupies a determining position corresponding to a predetermined point on a trajectory of a blade driven by the motor.Type: GrantFiled: June 27, 2001Date of Patent: March 9, 2004Assignee: Valeo Systemes d'EssuyageInventors: Paul Courdier, Phillipe Gougeon

Patent number: 6696806Abstract: A movable barrier operator (11) receives movement sensing signals from a sensor (13) and calculates corresponding speed of movement of a movable barrier. Such speed measurements lead to development of a median speed value over a monitoring window. The median speed value is used in a subsequent monitoring window to facilitate determining when speed of movement for the movable barrier has slowed in a way that likely corresponds to the movable barrier having encountered an obstacle.Type: GrantFiled: April 25, 2002Date of Patent: February 24, 2004Assignee: The Chamberlain Group, Inc.Inventors: Robert S. Study, Terence E. Crimmins

Patent number: 6696808Abstract: A windscreen wiper device and a method for wiping windscreens, including at least one motor whose direction of rotation can be altered, at least one wiper which is coupled to the motor and which moves back and forth between two reversing positions, a control device which switches the motor by means of switching signals and operating signals which are conveyed to the control device. The control device determines the switching signals from the operating signals to determine the reversing positions of the wiper. The degree of wetness of the windscreen surface is conveyed to the control mechanism and used as an operating signal.Type: GrantFiled: August 29, 2002Date of Patent: February 24, 2004Assignee: Valeo Auto-Electric Wischer und Motoren GmbHInventors: Bernd Schmid, Eberhard Hoegler

Patent number: 6657406Abstract: A method of operation for a motor-driven worm gear actuator coupled to a load device energizes the motor in a series of pulses during an initial period of motor operation when reversal of the motor is commanded. The pulsed energization produces a slow initial axial movement of the motor armature without moving the load device, minimizing the contact force between the armature shaft and a mechanical end stop of the motor. Rotation of the motor is determined by identifying and counting motor current pulses due to commutation, and the pulse count is adjusted at each reversal of motor rotation to compensate for motor current pulses due to the pulsed energization.Type: GrantFiled: September 19, 2001Date of Patent: December 2, 2003Assignee: Delphi Technologies, Inc.Inventors: Donald John Enzinna, Mark Joseph Parisi

Patent number: 6650076Abstract: A method and apparatus for moving a gate a distance in a predetermined period of time. In one embodiment the current load for an electric motor to move a gate is first measured to determine whether the gate's motion is being hindered or helped. A microprocessor then controls voltage supplied to the motor to enhance or retard the evolved power of the motor according to the load and the predetermined time.Type: GrantFiled: October 24, 2002Date of Patent: November 18, 2003Assignee: Elite Access Systems, Inc.Inventors: Wayne C.
