Abstract:
A multipurpose planting hand tool includes a handle provided for a user to hold, and a hook member fixed into the handle by a root portion of a rod body and extended from the front of the handle to a distance and bent into an arc to form a hook-shaped hand tool portion. A flat deformation occurs at a position where the hook member is bent into the hand tool portion, and sawteeth are formed at an inner curved edge. Both sides of an outer curved edge are extended upwardly and focused into a small arc to form a blade-like portion, and its front is tapered to form a sharp tip. The sawteeth, the blade-like portion and the sharp tip are provided to facilitate the work of collecting and removing weeds and fallen leaves after the operations of loosening soil, weeding, sweeping leaves and removing weeds.
Abstract:
A method for generating a lookup table for color correction for a display device includes obtaining measured stimulus values for grayscales of primaries displayed on the display device, obtaining target stimulus values for the grayscales of the primaries, and obtaining the lookup table by comparing the measured stimulus values for the grayscales of the primaries and the target stimulus values for the grayscales of the primaries. The measured display characteristic is employed to calculate the corresponding lookup table for color correction for the display device for achieving a desired color temperature and brightness curve. It makes the adjustment of color temperature and brightness more accurate and quicker, to reduce cost.

Abstract:
This present invention is a handle with a hidden belt, applying to a handle attached on a portable device, which uses torsion springs to draw the belt into the handle. Thus, a user can not only carry the portable device with the handle, but also shoulder or hang the portable device with the hidden belt of the handle.

Abstract:
A cover figure-displaying device for an electronic device includes a cover, a controller, and a light-emitting matrix. The cover has at least one figure. The controller has GPIO pins. The light-emitting matrix includes at least one light-emitting device connected with the controller. The controller controls the GPIO pins to select the lighting position, color, timing, and duration on the light-emitting matrix.
