| 20090195504 | Optical Pointing Device - An optical pointing device includes a light source, a light beam splitter, an image sensor and a lens. The light source provides an illumination light beam. The light beam splitter is disposed on a transmission path of the illumination light beam and configured for splitting the illumination light beam into a first light beam and a second light beam. The image sensor is for sensing the first and the second light beams. The lens is disposed before the image sensor. When the optical pointing device is put on a reflective surface, the first light beam is reflected to the lens by the reflective surface and then is focused on the image sensor. When the optical pointing device is put on a transparent body disposed on the reflective surface, the second light beam is reflected to the lens by the reflective surface and then is focused on the image sensor. | 08-06-2009 |

| 20090251414 | Optical Scrolling Module and Optical Control Module - An optical scrolling module includes a prism, a light source, an image sensor and a first condenser. The prism is disposed at an opening of an upper shell of a mouse and has a light incident surface, a reflective surface, a contact surface and a light emitting surface. The contact and light incident surfaces are respectively connected between the reflective and light emitting surfaces. The contact surface is exposed by the opening. A light beam from the light source is transmitted to the contact surface via the light incident and reflective surfaces. When an object with a pattern structure puts on the contact surface, the light beam is scattered and a portion of the light beam is transmitted to the image sensor via the first condenser. When the object is removed from the contact surface, the light beam is reflected to the light emitting surface by the contact surface. | 10-08-2009 |
