Abstract: A light-emitting diode assembly incorporates a power shunting element that provides electrical over-stress protection to a light-emitting diode (LED) and prevents damage to the LED from electrostatic discharge (ESD). The power shunting element is coupled in parallel to the LED within the LED assembly and protects the LED by diverting electrical current from the LED and limiting the voltage across the LED to a clamp voltage when a threshold voltage across the LED is exceeded.

Abstract: A down stop for a cross arm window regulator for moving a vehicle window between open and closed position is provided. The down stop comprises an elongated slider means which can either be fixed or made adjustable in length which is slidably received within a sash channel secured to the lower end of the window and between the guides carried by the cross arms of the cross arm window regulator. The slider means has its opposite ends engageable with the guides on the cross arm window regulator when the window has been moved to a fully open position to prevent further movement of the window.

Abstract: The present invention provides an apparatus and a method of the utilization of the same of a tape drive window regulator with a counterbalance. The counterbalance decreases the amount of torque required for the winder to raise the window glass. An embodiment of the present invention provides a window regulator wherein the drive tape is always in a tension mode.

Abstract: The present invention provides an improved tape drive window regulator apparatus and method of utilization of the same. The apparatus of the present invention provides a window regulator wherein the slack portion of the tape is laterally stabilized and/or deflected. In addition, an embodiment of the present invention allowed the tape to be placed in a loaded position in respect to deflector by the tape drive mechanism during assembly eliminating an assembly step.
