The present invention is a hand held portable remote such as a key fob that allows a user to interact with the security system using a flat panel touch-pad. The touch-pad input allows a user to rapidly select and control a large number of security functions, such as Arm, Disarm, Panic, garage door open, lamp on / off, and lamp dimming control, etc. The security device comprises a housing, a wireless communication port for interface with the security system, a touch-pad input device, and processing circuitry. In order to operate the security device, the user generates a user input by creating a contact motion on the touch-pad input device with a fingertip. The contact motion may consist of a swiping motion, a tapping, or a circular motion. In order to distinguish the contact motion clearly, when the fingertip contact comprises a wider than normal contact, it causes the processing circuitry to not generate an output signal. The security device also comprises an LCD display for displaying alpha numeric control options to a user and LED indicators for indicating the modes of the processing circuitry.

An object of the present invention is to provide a semiconductor wafer having a front and a back surfaces polished so as to have different glossiness from each other, yet with a lower cost. The glossiness of the front surface and the back surface can be selected arbitrarily. In a double-sided polisher with no sun gear, silicon wafers W are inserted in respective holding holes 11a of a carrier plate 11. The wafers W are placed with their back surfaces facing up. An expanded urethane foam pad 14 is pressed against the back surfaces of the wafers W and a non-woven fabric pad 15 is pressed against the front surfaces of the wafers W. A carrier holder 20 and thus the carrier plate 11 are then driven to make a circular motion associated with no rotation on their own axes within a horizontal plane while supplying a slurry to the wafers W from an upper surface plate 12 side. As a result, each of the front and the back surfaces of respective silicon wafers W can be polished uniformly over entire area thereof respectively. At that time, the urethane pad 14 has a sink rate of the wafer lower than that of the non-woven fabric pad 15. Therefore, such a polished wafer having the back surface formed into a satin-finished surface and the front surface formed into a mirror-finished surface can be obtained. Alternatively, those polishing cloths having different sink rates from each other may be employed for the upper and the lower surface plates, respectively. Further, the upper surface plate and the lower surface plate may be rotated at different speeds from each other. Those methods are also advantageously used to manufacture the semiconductor wafer having different glossiness between the front surface and the back surface thereof.

A power toothbrush with a drive train that is easy to manufacture, reliable in service and that enables multiple heads or other complex design or functional elements is provided. In an illustrative embodiment, the power toothbrush includes a sealed case that encloses a motor with a pinion gear joined to an eccentric link. This eccentric link can be a circular rack having an eccentric pin that rides in a slot on a drive plate.

The head assembly includes one or more moving disks that are each connected to generally circular brush heads, which project outwardly from the head assembly. One disk receives a bent end of the drive shaft in a hole located eccentrically to the axis of rotation. When the circular rack rotates in a single direction, it drives the shaft in a reciprocating motion that, thereby, rotates the disk in a corresponding reciprocating circular motion about its axis. Additional disks can be linked by a short connecting shaft or link to the first disk via eccentric holes—other linkages, such as mating gears between disks can be used to simultaneously drive further disks, thereby providing a multiple moving-head power toothbrush.
