    摘要： A single low side power transistor switch is used to efficiently control a brushed motor in a forward rotational direction. A boost voltage power supply is used to supply voltage to the brushed motor in a reverse rotational direction and/or braking from the forward rotational direction. A digital device controls the brushed motor rotational speed and rotational directions.

    摘要： A multilayer printed circuit board provides both physical and electrical attributes necessary for creating an inductive touch sensor panel. Inductive sense coils are formed on a surface of first layer of the multilayer printed circuit board. A second layer is used as a spacer between the first layer and a third layer. The first, second and third layers of the multilayer printed circuit board form chambers in which the inductive sense coils are disposed therein. When a force is applied to a portion of the third layer proximate to an inductive sense coil, a metal target on a face of the third layer is biased toward the inductive sense coil and thereby changes the inductance value thereof.
