Abstract: A switching method of video setting for a video conversion system includes generating a static metadata change flag when a static metadata change event is detected, repeating an output video after the static metadata change flag is generated, updating a video setting according to a static metadata corresponding to an input video when the output video is repeated, and converting the input video into the output video according to the video setting to display the output video.

Abstract: A lighting device includes a mount, a first seat, a switch and a fixture. When the mount is connected to the fixture, the fixture contacts the switch to activate the circuit, and the second seat on the fixture, the light source and the first seat are electrically connected to the exterior power source. When the fixture is removed from the mount, the switch is shut off to protect the users from electrical hazard.

Abstract: A carbon brush holder with improved air vents includes a body, a housing, and an exhaust lid, which are provided with corresponding fixing structures for their convenient assembly or disassembly. The exhaust lid is formed with a diverging air channel. By the exquisite configurations of the fixing structures provided on its components, the carbon brush holder is easy to assemble and disassemble so as to facilitate replacement or repair of parts settled in the carbon brush holder. Besides, since the exhaust lid in the present invention has the diverging air channel opened at two sides thereof as the air vents, it significantly improves the efficiency in dust expelling and heat dissipating, thereby effectively preventing the air vent from blocked and preventing overheat caused by poor exhaust.

Abstract: A circuit and a method for image processing are provided. The image processing circuit has an adaptor and a sharpening circuit. The adaptor has a processing unit and a weight generator. The processing unit receives an input video signal, and the input video signal has information of a plurality of pixels. The processing unit processes the input video signal to calculate a color difference value of a target pixel of the pixels. The weight generator generates a weighting signal according to the color difference value. The sharpening circuit performs a sharpening operation on the input video signal according to the weighting signal to generate a sharpened video signal.

Abstract: An improved heat sink module includes a main body and at least one diode. Mounting brackets, each having a through hole, extend from the outer periphery of the arcuate main body. A plurality of engaging holes are formed on the backside of the main body and each have at least one vent slot. To increase the heat dissipation area and yield rate of the main body, a plurality of upright, alternately arranged first and second fins are provided on the front side of the main body. The first fins extend between the inner and the outer peripheries of the main body, whereas the second fins extend from the outer periphery toward the inner periphery but are spaced therefrom. Each diode is peripherally provided with engaging ribs and has a wired end. The vent slots allow the at least one diode to be inserted into the engaging holes without difficulty.

Abstract: A welding assembled structure of a diode in a rectifier is disclosed. Therein, a solid joint lead which is a lengthwise member with one end contacting a leader frame of the rectifier, and an opposite extended end bent and extended outward the leader frame, while having a soldering tag located at one side of the extended end. The diode has a pin with an extended end located in a restricting area defined by the solid joint lead and the soldering tag. The soldering tag is welded by a spot welding process and bent toward the solid joint lead under stress when melted at a high temperature and, so as to deform and clamp the pin of the diode together with the solid joint lead, thereby fix-clamping the pin of the diode. The diode is secured by spot welding from loosening during operation, thereby ensuring the performance of the rectifier.
