Abstract: A two-dimensional navigation module of a cursor controller includes a top plate, a first rod, a sliding roller sleeved at the first rod, and a first OTS sensor. The top plate has an elongated groove recessed thereon. The first rod is arranged in the groove. Two opposite ends of the first rod are fastened to the top plate. The sliding roller is movable along the first rod between a first position and a second position, and the sliding roller is spinable along the first rod in a range of 0˜360 degrees. When the sliding roller is moved, a center segment of the first rod keeps touching the sliding roller. The first OTS sensor is arranged under the center segment of the first rod for detecting at least one of a moving distance and a spinning angle of the sliding roller.

Abstract: An optical navigation device has a light-emitting unit, an optical navigation chip and a cover. The light-emitting unit provides a light to a surface of a displacement generating unit. The optical navigation chip has a sensing array, but excludes any optical lens for focusing a reflected light. The sensing array disposed opposite to the surface of the displacement generating unit receives the reflected light which the light provided by the light-emitting unit is reflected from the surface of the displacement generating unit. The cover has a first surface and a second surface, and an angle is formed between the cover and the optical navigation chip, to prevent another reflected light from the surface of the first surface of the cover from entering the sensing array. Particularly, the angle formed between the cover and the optical navigation chip is from 10 degrees to 15 degrees.

Abstract: An optical processing apparatus and a light source luminance adjustment method adapted to detect a rotational displacement and a pressing state are provided. The optical processing apparatus includes a light source unit, a processing unit, and an image sensing unit, wherein the processing unit is electrically connected to the light source unit and the image sensing unit. The light source unit provides a beam of light. The processing unit defines a frame rate, defines a plurality of time instants within a time interval, and sets the light source unit to a luminance value at each of the time instants. A length of the time interval is shorter than the reciprocal of the frame rate. The luminance values are different and are within a range. The image sensing unit captures an image by an exposure time length at each of the time instants, wherein the exposure time lengths are the same.

Abstract: An electronic device with waterproof structure includes an assembly and a manipulation member movably disposed on an outer surface of the assembly. The assembly includes a case and an optical detection module. The case defines a waterproof space and has a translucent region. The optical detection module is arranged in the waterproof space. The optical detection module has a lighting unit and a sensor array. Light emitted from the lighting unit enables to travel out of the waterproof space by penetrating through the translucent region. At least part of the manipulation member is corresponding in position to the translucent region. The lighting unit is configured to emit light onto the manipulation member, and the sensor array is configured to receive the light reflected from the manipulation member.
