Abstract: The invention discloses a circumferential laser dynamic display device, including an inner frame, having an inner frame pattern with multiframe microstructures made on surface; a sheet metal part, at least provided with first and second through holes, wherein the inner frame pattern is directly irradiated by a first beam of laser through the first through hole and by a second beam of laser through the second through hole; and a rotating shaft, with one end fixedly connected with a driving shaft, and the other end rotatably connected with the inner frame pattern. The rotating shaft can drive the inner frame pattern to do translational movement when rotating; wherein the translational movement of the inner frame enables the inner frame pattern to do circumferential movement relative to laser. The dynamic display device disclosed by the invention has simple structure, reasonable design and low production cost, and achieves circumferential dynamic image display.

Abstract: A compact warning light employs LED lamps as a light source and has a lighthead configured for insertion into the reflector shells of a motor vehicle such as a sedan or SUV. The lighthead has a base and cover which define a sealed interior space surrounding the LED lamps. The base is constructed of heat conducting material and the LED lamps are secured to the base so that heat generated by the lamps is conducted away and dissipated by the base. The base may include a post for supporting a plurality of individually energized arrays of LED lamps. The cover may be optically clear, tinted or provided with facets or a surface texture.

Abstract: A docking adapter that interacts with an entertainment system and a parallel television device. The docking adapter may comprise a housing shaped for removable insertion of the parallel television device. The docking adapter may deliver power to the parallel television device. The docking adapter may comprise a communication pathway that carries media flow disposed on the housing. At least one module may receive a user input identifying a video selection. The communication pathway may carry the user input to the parallel television device. The parallel television device may generate a control signal that causes display of video information corresponding to the video selection on the entertainment system. The docking adapter may alternately or in addition receive the video information for display on a built-in screen of the docking adapter. The docking adapter may also deliver the video for display on a screen of the parallel television device.
