Patent number: 9739322Abstract: A clutch module which includes a first rotating member including at least one strut actuation module and a second engaged member including cam surfaces thereon for engagement by said strut actuation module. The strut actuation module includes a frame with a strut pivotally movable with respect to the frame. The strut includes an engagement end and a base end including a first side and a second side thereof. A pin or post portion extends from the frame and has an insulated bobbin with an energizable coil surrounding the bobbin. A U-shaped member including a pair of actuation legs is attached to the pin member and forms a magnetic gap between the base end of the strut and peripheral ends of the legs, such that when the coil is energized the peripheral ends of the legs are polarized in a first polarity and the frame and the strut are polarized with an opposite polarity thereby biasing the strut toward the peripheral ends and pivoting the actuation end into engagement with a cam surface of the engagement member.Type: GrantFiled: September 3, 2015Date of Patent: August 22, 2017Assignee: Magna Powertrain of America, Inc.Inventors: Darrell Greene, Adrian Cioc

Publication number: 20070241707Abstract: A system for controlling a displacement drive of a motor vehicle includes a manually operable actuator movable over a fixed stroke between a first end position and a second end position. The actuator is biased to a neutral position centrally located between the first and second end positions and provides a signal representative of position of the actuator. A controller receives the signal from the actuator and produces commands for a reversible DC electric motor of the displacement drive device. The commands vary speed of the drive motor based on the position of the actuator such that the speed of the drive motor is zero at the neutral position, increases in one direction as the actuator moves toward the first end position, and increases in the other direction as the actuator moves toward the second end position.Type: ApplicationFiled: March 23, 2006Publication date: October 18, 2007Inventors: Darrell Greene, Pascal Garrido

Publication number: 20070228786Abstract: A powered adjustable seat assembly for a motor vehicle includes a seat, an adjuster mechanism operatively connected to the seat to adjust the seat, a controller operatively connected to the drive motor of the adjuster mechanism to selectively adjust the seat, and a plurality of lights located below the seat and operatively connected to the controller to selectively illuminate the lights upon predetermined conditions. The lights are secured to a moving portion of the adjuster mechanism so that the lights move with the seat. Preferably, one of the lights is positioned to direct illumination in a forward direction toward operator pedals, one of the lights is positioned to direct illumination in a rearward direction toward a rear seat, and one of the lights is positioned to direct light in a lateral direction toward a vehicle door.Type: ApplicationFiled: April 4, 2006Publication date: October 4, 2007Inventor: Darrell Greene

Publication number: 20070164619Abstract: An electric motor including a rotational sensor is provided. Certain examples of the rotational sensor are operative to output a sinusoidal signal that corresponds to the rotational position of the motor armature in response to the potential at a single point or multiple points on the commutator. Certain other examples of the motor and rotational sensor disclosed here are operative to provide multiple pulses per rotation of the armature, which can allow for finer adjustment of devices attached to the motor. The motor and rotational sensor provides a simpler and less costly design requiring fewer parts subject to mechanical failure.Type: ApplicationFiled: March 23, 2007Publication date: July 19, 2007Applicant: Dura Global Technologies, Inc.Inventor: Darrell Greene

Publication number: 20060220600Abstract: A motor vehicle seat adjuster includes a DC motor and a control system operably connected to the motor to control seat motion to a desired motion profile. Power to the motor is variable from less than 100% of normal power to greater than 100% of normal power. The desired motion profile preferably includes a normal operating power and a boost operating power and the control system automatically increases motor power to the boost operating power after one of a predetermined period of time, a predetermined distance of travel, or a predetermined sensed condition. Parameters of the motion profile are preferably customizable.Type: ApplicationFiled: March 7, 2006Publication date: October 5, 2006Inventors: Darrell Greene, James William Mondry, Dave Parent, Charles Flynn

Publication number: 20060145549Abstract: An electric motor includes a rotation shaft and an armature coupled to the rotation shaft. A commutator is coupled to the rotation shaft and is electrically connected to the armature. At least two power brushes are fixed relative to the commutator for electrically coupling the armature to a power source. A rotational ring independent of the commutator is also coupled to the rotation shaft. At least one sensor brush is fixed relative to the rotational ring for detecting a voltage. The rotational ring includes a plurality of segments. At least two of the plurality of segments are electrically connected to the commutator through a diode.Type: ApplicationFiled: January 4, 2005Publication date: July 6, 2006Inventor: Darrell Greene
