Patent number: 7707918Abstract: Improved methods to detect when a human body contacts a predetermined portion of a machine are disclosed. The methods distinguish contact with a person from contact with other materials. The methods are particularly applicable in woodworking equipment such as table saws to distinguish contact between a person and the blade of the saw from contact between the blade and wet or green wood.Type: GrantFiled: January 26, 2009Date of Patent: May 4, 2010Assignee: SD3, LLCInventors: Stephen F. Gass, Paul J. Lingane, Arjuna R. Karunaratne

Patent number: 7667425Abstract: The invention relates to a method and a device for controlling an electric door drive. During a learning process determination of the course over time of the torques of the door drive for each of at least one opening process and closing process is carried out. Maximum permissible torques are derived from the ascertained torques for predetermined zones within an opening process and closing process. During operation of the door drive a comparison of the current torque with the maximum torques and a comparison of the current speeds of the door drive with predetermined target speeds are carried out. The current speed of the door drive is increased if the associated target speed is fallen below. In addition, switching-off the door drive takes place if the current torque exceeds the associated maximum torque.Type: GrantFiled: February 20, 2004Date of Patent: February 23, 2010Assignee: Sommer Antriebs- und Funktechnik GmbHInventor: Frank Sommer

Patent number: 7663330Abstract: An actual detected current value and a target voltage value of an electric motor are subjected to a low-pass filter process, and amounts of change per time in the filtered actual current value and the filtered target voltage value are calculated. If the amount of change in the actual current value on the increase side is greater than a criterion value and the amount of change in the target voltage value on the decrease side is greater than a criterion value, it is judged that the stroke end has been reached. Then, the upper limit value of the target current value is set at the actual current value obtained in the immediately previous cycle of the feedback control, so as to prevent generation of unnecessary torque.Type: GrantFiled: February 13, 2007Date of Patent: February 16, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventor: Ippei Yamazaki

Patent number: 7649332Abstract: A motor control system uses an incremental encoder that provides a signal indicative of motor position. If an illegal state change is detected in the same sampling interval, an error event is recorded and an error counter is incremented. When the number of counts exceeds a pre-determined threshold, the motor is disabled so that appropriate corrective action can be taken.Type: GrantFiled: September 20, 2007Date of Patent: January 19, 2010Assignee: Rockwell Automation Technologies, Inc.Inventor: Thomas D. Lundell

Patent number: 7633252Abstract: A stall protection circuit is provided for bidirectional motor operation that is controlled by a half bridge switch that has forward, reverse and off positions. A method of protecting a motor is also disclosed. A Hall effect current sensor may be provided in a stall current protection circuit that engages a latching circuit. The latching circuit is operative to interrupt current flowing to the motor by disabling MOSFETs on opposite sides of the motor. Alternatively, FET voltage from drain to source may be used to measure the current supplied to the motor that is used to engage the latching circuit.Type: GrantFiled: April 14, 2005Date of Patent: December 15, 2009Assignee: Lear CorporationInventors: H. Winston Maue, John F. Nathan, Michael Pajor, Michael Noorman, John R. Ballard, Jerremy Anderson, Paul Kucher

Patent number: 7621460Abstract: A speed control system is provided for controlling temperature within a chassis. The chassis includes therein a temperature sensing device for producing a temperature signal representative of temperature within the chassis, a fan, and a fan speed controller. The fan speed controller produces a nominal fan speed control signal comprising a train of pulses, successive pulses having a duty cycle related to the temperature signal produced by the temperature sensing device, such time durations decreasing with increasing temperature. The speed control system includes a decoupling circuit responsive to the nominal fan speed control signal for, in response to relatively a low duty cycle, coupling the nominal fan control signal to an output of the decoupling circuit, and, in response a relatively high duty cycle, producing a preset fan speed signal at the output of the decoupling circuit. The fan has a speed in accordance with the signal at the output of the decoupling circuit.Type: GrantFiled: September 29, 2005Date of Patent: November 24, 2009Assignee: EMC CorporationInventor: Timothy Dorr

Patent number: 7605553Abstract: A system for safely opening/closing a power window of a vehicle includes a main opening/closing device provided adjacent to a driver seat so as to open and close a window of a passenger seat. A sub opening/closing device is provided adjacent to a passenger seat so as to open and close a window of a passenger seat. A plurality of main electrodes of the main opening/closing device includes at least one main ground electrode for generating a signal. A main center electrode is electrically connected to a sub opening/closing device and to at least one main ground electrode by a main switch, and is disposed on a portion of a main plate to be prevented from being electrically connected to a main ground electrode when a main switch moves.Type: GrantFiled: December 8, 2005Date of Patent: October 20, 2009Assignee: Kia Motor CorporationInventor: Chul Ho Lee

Patent number: 7605554Abstract: Methods are provided for detecting and alleviating the pinching of an object in a window of a vehicle having a drive unit motor controlling a window based upon current signals received from a control switch, security system remote control, or security system controller. The detection method includes determining a current threshold for the motor, determining time required to close the window, monitoring drive unit motor current draw during a window close operation, and determining if the current threshold is reached before window close time has elapsed. The alleviation method includes determining a current threshold, determining window close time, monitoring drive unit motor current draw during a window close operation, determining if current threshold has been reached before window close time has elapsed, and positioning the window so the drive unit motor current is less than the current threshold. The methods can be programmed into a window control module.Type: GrantFiled: November 9, 2006Date of Patent: October 20, 2009Assignee: DEI Headquartes, Inc.Inventor: Joseph Kunkel
