An electrical circuit, planar diode, and method of forming a diode and one or more CMOS devices on the same chip. The method includes the step of determining whether an at least first object is located within a proximal distance of the first surface of the display screen based on information provided by a depth camera. This two-stage linkage and cable design maximizes the movement of the slip assemblies while minimizing vertical movement of the power slip’s housing. The lamp section is retractable into an elongate base section that is shaped and structured to receive the lamp section snugly in its interior.
