Abstract: The invention relates to a rearview mirror device for vehicles incorporating a radio-frequency reception system. The rearview mirror device comprises: a light-reflective surface made of an electrically conductive material, and at least one planar conductive element lying on a plane substantially parallel to said reflective surface. The light-reflective surface and said conductive element are capacitively coupled and are used in combination for the reception of radio-frequency signals. The invention provides a rearview mirror with great simplicity and very-low cost.

Abstract: A semiconductor device with a semiconductor die thereon and a contactor board are electrically coupled when the electrically conductive elements on the semiconductor device and the contactor board are in physical contact. A continuous electrically conductive path is formed with electrically conductive elements involving both the semiconductor device and the contactor board. A complete electrical circuit involving both the semiconductor device and the contactor board is formed only when the relative orientation of the semiconductor device and the contactor board have predetermined relationship and the electrically conductive elements of the two boards are in good physical contact.

Abstract: In order to protect two inter-connected circuits, each powered by different power rail, a circuit is placed between the power supply and the associated power rail. The circuits for both rails are coupled. In this manner, potentially component-damaging power transients are prevented from reaching the power rails. In addition, the power rails are prevented from being separately activated. The extension of the present circuit to more than two power rails is described.
