In one embodiment, the present invention provides an input device with a mechanical wheel which includes a touch sensor. In one embodiment, the wheel is a thumbwheel that uses a magnetometer to detect rotation of a magnet inside the thumbwheel. The touch sensor in one embodiment is a cylindrical floating electrode which is capacitively coupled to a bridge electrode connected to a sensing circuit. The thumbwheel may be used for horizontal scrolling, zoom and other gestures.

Rotational element enabling touch-like gestures

A method for constructing a wireless communications apparatus includes attaching a three dimensional antenna having a first end and a second end to a printed circuit board (PCB) using a spring-loaded attachment mechanism. The three dimensional antenna is attached in an orientation that is perpendicular to a mounting surface of the PCB. The first end of the three dimensional antenna is further soldered to the PCB.

A roller for a mouse includes a roller wheel having an outer portion formed of metal and a corrugated surface; a pivot arm configured to pivot in a first direction to contact the corrugated surface and to pivot in a second direction to move away from the corrugated surface; and user operable device configured to be translated to pivot the pivot arm.

Multi-function roller apparatus and method for a control device

A system and method for controlling friction between a mouse and the surface upon which it is placed. Reduction of friction can be accomplished in several ways, including: making the feet of the mouse from various different materials, creating layers of air between the mouse and the surface, creating beveled edges for the feet of mouse, etc. In one embodiment, the feet of the mouse are made of a piezo-electric layer bonded to another layer made of a different material. Exciting the piezo-electric layer at certain frequencies makes the two layers shrink and expand differently, thus creating oscillations of the feet. In yet another embodiment, portions of the mouse feet are made of different materials with different coefficients of friction. These different portions of the feet can be pressed down onto the surface with varying amounts of pressure, thus altering the friction.
