Abstract: In one example, a mouse may include a base for movement along a horizontal surface, first and second sets of pins disposed in the base, and an upper shell movable relative to the base between multiple mode positions. The upper shell may include a first button and a second button. The first button and the second button may electrically connect to the first set of pins in a first mode position. The first button and the second button may electrically connect to the second set of pins in a second mode position to switch functions of the first button and the second button.

Abstract: A device matching verification method is provided. The device matching verification method includes reading, respectively, first color code information stored in a cradle device and second color code information stored in a memory device of an electronic device; transforming the first color code information to display a first color code on a first display region of a display device of the electronic device; transforming the second color code information to display a second color code on a second display region of the display device; and determining whether the cradle device matches the electronic device or not according to the first color code and the second color code.

Abstract: A system for interactive media skimming and search on a device comprises a scene manager building a model of a 3D scene of a multimedia segment of the media visible on a screen of the device, facets of scene objects in the 3D scene are used to dynamically convey visual imagery as a texture from a multimedia source and maintaining a logical navigable relationship between the scene objects, the object facets and the multimedia segments, and further comprising an interaction manager, a user manager securely storing user information and preferences, a playback component initiating rough or high definition playback, a texturizer creating a 2D texture artifact from a set of the multimedia segments in the media for a 3D facet, a transformer transforming and modifying pixels, a cache and scene heuristics maintaining a set of 3D scenes comprising objects, object facets, a virtual camera, and positions of the objects.

Abstract: An optical structure is characterized by improving a primary lens of a photovoltaic concentrator system. The optical structure is accomplished by properly dividing the primary lens, determining required optical operational regions, and arranging the optical operational regions basing on an identical location into an annular array, thereby forming the complete optical structure. The optical structure facilitates enhancing uniformity of light distribution throughout the optical operational regions, improving photoelectric conversion efficiency of a solar cell having the optical structure, and reducing operational distance between the primary lens and the solar cell.
