Abstract: A light guide plate structure includes a body and a plurality of microstructures. The body includes a first surface, a second surface, and a light incident surface. The light incident surface is connected to the first surface and the second surface. The light incident surface faces a light source, and light incident by the light source via the light incident surface has a light source direction on the body. The microstructures are formed on the first surface and have crests and troughs along a second direction, where projections of the crests on the first surface are distributed on a plurality of first wave trajectories, each of the first wave trajectories extends along the light source direction, and the troughs have ups and downs in the first direction. The light guide plate structure may improve the optical grade of pictures of a display device. A backlight module is also provided.

Abstract: A method and a system for wireless positioning are provided. Multiple received signal strengths corresponding to multiple wireless access points are measured by a user device. The received signal strengths include multiple first received signal strengths. A reference positioning position is obtained according to positioning reference information provided by the user device. A first positioning position based on the first received signal strengths is obtained. The reference positioning position is compared with the first positioning position. In response to the distance between the reference positioning position and the first positioning position being greater than a tolerance value, at least one of the first received signal strengths is excluded from the multiple received signal strengths, so as to obtain multiple filtered received signal strengths. A user position of the user device is obtained according to the filtered received signal strengths.

Abstract: A front light module applied to full lamination includes a display, a front light guide plate, a light-emitting unit, a transparent medium, and a cover layer. The front light guide plate is located over the display and includes a micro-structure. The micro-structure is recessed from an upper surface of the front light guide plate. The light-emitting unit is adjacent to the front light guide plate. The transparent medium is located over the front light guide plate. A space is located between the front light guide plate and the transparent medium. The cover layer is located over the transparent medium.

Abstract: The present invention provides a light guide plate having a light exit surface, a light incident surface and a bottom surface. In the said light guide plate, the bottom surface is opposite to the light exit surface, and the light incident surface connects the light exit surface and the bottom surface. A plurality of light guide structures are formed on the bottom surface, and each of the light guide structure includes a front mound protruding above the bottom surface, a back mound protruding above the bottom surface and located at the side of the front mound opposite to the light incident surface, and a concave eye-shaped portion caved in from the bottom surface and located between the front mound and the back mound.

Abstract: A method for reducing file storage area includes duplicating a original disk image file of an operating system to a storage device of a computer, duplicating a plurality of add-on disk image files to the storage device, and installing the original disk image file of the operating system and at least one add-on disk image file to the storage device of the computer. The plurality of add-on disk image files are different language packages, different package specific software or different SKU packages.

Abstract: A portable electronic device includes a pivot unit coupled to a main housing and a cover body such that the cover body is pivotable about a longitudinal axis parallel to a top surface of the main housing, and about a vertical axis transverse to the top surface of the main housing. A virtual control key module configures a display panel mounted on a first surface of the cover body to show simulated control keys thereon when the portable electronic device is operated in a mode, where the cover body is superimposed on the main housing such that a second surface of the cover body opposite to the first surface faces toward the top surface of the main housing. The simulated control keys have distinct functions assigned thereto and are available for selection so as to enable execution of the function assigned to a selected simulated control key.

Abstract: A device for manually turning-on at least one circuit-breaker from the front panel of a cabinet includes at least one sleeve having a front end and a rear end. The sleeve extends through an aperture in the front panel and is movable between a backward position, in which the front end of the sleeve projects slightly from the front panel, and a forward position, in which the front end of the sleeve projects away from the front panel. A spring is compressed to push the sleeve from the forward position to the backward position. A rod is operably connected to the sleeve so as to be displaced following the forward movement of the sleeve and to remain in its position uneffected by the backward movement of the sleeve.
