The method comprises detecting the direction of the desired movement; detecting a movement of the vehicle in the direction opposite the desired direction; calculating a torque to be applied by the motor to the at least one wheel to counteract the movement of the vehicle in the undesired direction; and applying the counteracting torque to the at least one wheel via the electric motor.

Abstract: A bumper for attachment to the front of a vehicle, includes an elongated bumper beam having a front face provided with at least one rearwardly depressed portion extending lengthwise of the bumper beam, a compressable energy absorbing foam material extending lengthwise of the bumper beam, and a bumper fascia covering the foam material. The foam material has a first portion received in the depressed portion and a second portion protruding forwardly from the front face of the bumper beam such that the second portion is compressed into the depressed portion upon receipt of a collision impact.

Abstract: The high spin golf club uses modified grooves for use on all types of known golf clubs, wherein the modified grooves maximizes control of the golf ball through increasing backspin. The high spin golf club's modified grooves can be used alone or in a combination with conventional grooves to tailor the properties of the club face. The modified grooves are of varied configurations and all modified grooves can be used in combination with any other modified or conventional grooves to maximize the backspin of the golf ball and tailor the spin properties of the face of the club. Further a method for making high backspin golf clubs that reduce cover damage of golf balls is disclosed.

Abstract: A theft detection system includes an accelerometer attachable to an object, the accelerometer providing an acceleration signal in response to movement of the object; an alarm mechanism for providing a signal in response to movement of the object; and for preventing false alarms, a filter programmed to determine the frequency of the acceleration signal and to provide an output to activate the alarm mechanism only when the frequency of the acceleration signal meets a predetermined criteria.

Abstract: An improved window sash lock keeper is provided having a slot to provide clearance for a burr, which is typically found on a surface upon which such a sash lock keeper is mounted. The improved keeper is typically mounted flush to a surface of an extruded window component. The clearance slot allows the keeper to be mounted with improved precision and thereby reduces interferences caused by misaligned window hardware.
