Abstract: A light emitting key is disclosed. A through hole is made through piezoresistive layer; a light source is arranged under the bottom of the light emitting key. When the light source is turned on, light beams shall emit out of the top substrate. The light emitting effect of the key facilitates it to be used in a dark area such as an aircraft flying in the night sky.

Abstract: A resistive input system is disclosed, which includes a resistor matrix. The resistor matrix includes M first traces, N second traces, and M*N resistors. First ends of the resistors of a same column are coupled to one of the M first traces, second ends of the resistors of a same row are coupled to one of the N second traces, M is integers greater than 1, and N is integers greater than and equal to 1. The M*N resistors include variable resistors. A measurement circuit measures variations of a first voltage level of each of the second traces while a power control circuit provides the first voltage to the one of the M first traces and the second voltage to the rest of the M first traces. At least one input point is determined according to the variation of the first voltage level of each of the second traces.
