A control switch incorporates a solid state transducer, a strain gauge. The chemisorption product of the first and second substance may include silicon and nitrogen. The interface device may be a vehicle interface device such as a head unit or infotainment system, and the portable device may be a smart phone, media player, or other computing device capable of displaying graphical information. Further, a carrier segment is attached to the first cross section of the chip segment and the conjoined carrier segment and the chip segment are attached to a pad segment so as to form a stacked structure. For multiple channel transfers to hard disk drive storage, a multiplexed IDE host interface is provided with shared pins for data, address, and chip-select lines of the IDE interface so that multiple hard drives may be interfaced using the common pins of the integrated circuit. The drawer may be automatically moved in forward and backward directions.
