Illumination for optical touch panel
An optical touch panel including a support defining a generally planar surface, an optical illumination assembly arranged along and above at least part of a periphery of the support to define a detection region, at least one light detector, arranged to detect changes in the light received from the optical illumination assembly produced by the presence of an object in the detection region and detection circuitry receiving at least one output from the at least one light detector and providing an output indication of the two dimensional location of object impingement in the detection region.

Optical touch screen
An optical touch panel including a support, an optical fiber illumination assembly arranged along and above at least part of a periphery of the support to define a detection region, the assembly including at least one optical fiber and a light source arranged for directing light along the at least one optical fiber, at least one light detector, arranged to detect changes in the light received from the optical fiber illumination assembly produced by the presence of a finger or stylus in the detection region and detection circuitry receiving at least one output from the at least one light detector and providing an output indication of the two dimensional location of finger or stylus impingement in the detection region.

Dual mode computer mouse
A dual mode computer mouse including a first mouse body and a second mouse body is disclosed. The first mouse body includes a first sensor, a first button and at least a second button. A second sensor is disposed either in the first or the second mouse body. The second mouse body includes a third button and is hinged to one tail end of the first mouse body. The first mouse body and the second mouse body can rotate relatively. When the dual mode computer mouse is in a palm-type configuration, the first button and, third button and the second sensor are activated. When the dual mode computer mouse forms a pen-type configuration, the third button is activated and the first sensor is in an activated state.
