Abstract: A display system includes a display device and an HDMI dongle electrically connected to the display device. The display device includes a first transmission interface, a first control module, and a power supply module. The HDMI dongle includes a second transmission interface and a second control module. The first and the second transmission interfaces include transmission pins corresponding to each other. The first control module detects voltage of one pin to obtain matching state between the display device and the HDMI dongle and outputs an enabling signal. When the HDMI dongle matches the display device, the enabling signal controls the power supply module to transmit the power supply signal to the second control module through the first and the second transmission interfaces for charging the second control module. When the HDMI dongle does not match the display device, the power supply module is not transmitted to the second control module.

Abstract: A chain plate structure includes a link plate body and a sleeve. The link plate body has an acting surface being provided with a first approach edge, two combining portions, and a limiting block located adjacent to the first approach edge. The limiting block has an altitude higher than an altitude of the acting surface. The sleeve is mounted on the link plate body and has a through hole whose maximum diameter is greater than a maximum diameter of a raised ring peripherally formed on the corresponding one of the combining portions. Therefore, when two of the link plate bodies are combined together, a first space is formed between the acting surfaces of the two aligned link plate bodies. The limiting block serves to limit the first space, while the sleeve is allowed to move on one of the combining portions so as to provide a second space.

Abstract: A hanging support for hanging a panel display on a flat surface includes a mounting structure and a support structure. The support structure fixes the panel display on the mounting structure. The mounting structure is mounted on the flat surface and adjusts an angle between the panel display and the flat surface. The support structure includes a top holder, a bottom holder, and a main holder. The top holder, the bottom holder, and the main holder corporately define a clamping space to clamp two opposite edges of the display panel.

Abstract: A display apparatus adaptable to being placed in different locations includes a frame, a display panel received in the frame, at least one rotating portion rotatably connected with the frame, and a base rotatably connected to the at least one rotating portion. The at least one rotating portion is parallel with a back surface of the frame. The base can be perpendicularly located under the frame to support the display apparatus in a first placing orientation, on a table for example, or the center of the base can be swung through 180 degrees to rest substantially flush against the back of the display panel when it is desired that the display apparatus be hung from a wall for example.

Abstract: A link plate, wherein a combining portion is correspondingly configured on each of the two ends of a link plate body, wherein an axle hole is configured on each combining portion and a middle portion is configured between the two combining portions, wherein an arc-shaped connection surface is configured at the junction between the middle portion and a corresponding one of the two combining portions, wherein each connection surface has an inner edge and an outer edge forming borders with the middle portion and a corresponding combining portion, respectively, and being configured as equidistance double arcs, and wherein at least one protrusion protruding from the middle portion is configured between the two connection surfaces.

Abstract: A connection unit of a chain includes two outer link plates each having a first hole and a second hole. The second hole has a first recess and a second recess which communicates with the first recess. The first recess has a diameter larger than that of the second recess. The second recess includes an inner surface and a stepped engaging surface which is perpendicular to the inner surface. A stop surface is perpendicularly connected to the engaging surface. At least one first protrusion extends from the inner surface. A pin is securely fixed in the first hole and includes an engaging portion. A neck is located beside the engaging portion and has a diameter smaller than that of the engaging portion.

Abstract: A flat panel display device includes a rear housing defining a containing space, a support member disposed in the containing space and secured to the rear housing, a display panel secured to a front face of the support member, a front frame, and a motherboard. The front frame covers a peripheral portion of a front face of the display panel, is connected to the rear housing, and includes light guides extending into corresponding holes in the front frame. The motherboard includes a board body secured to a rear face of the support member, a plurality of press buttons disposed on the board body and extending respectively holes in the rear housing, a plurality of light-emitting diodes disposed at the board body, and a wireless signal receiver disposed on the board body. The light-emitting diodes and the wireless signal receiver correspond to the rear ends of the light guides.

Abstract: A forming method for applying a continuous punching to a chain roller includes a raw block having a first surface and a second surface. The raw block would be sequentially punched and formed throughout the first to sixth punching or throughout the first to seventh punching. During the fourth punching, a first blanking would be executed. Alternatively, before executing the sixth or the seventh punching, a second blanking would be implemented.

Abstract: A dual-purpose pliers adapted to chain link applies to concurrently promote a separation of two first jaw parts or an approach of two second jaw parts, which is conducive to a convenient detachment or assemblage of a master chain link via merely using a driving tool. Further, each jaw part forms a curved brim represented by an arcuate contour, a serrated shape, or the combination thereof. Accordingly, the curved brim serves to encircle and lean against a periphery of a chain pin of the chain for a stable manipulation.

Abstract: A pliers for chain link includes a left pliers body, a right pliers body, a pin and an elastic member. The left pliers body and the right pliers body are connected either in a parallel form or in a cross form. Center portions of the left and right pliers bodies are connected by the pin. The elastic member is located between the left and right pliers bodies. The left and the right pliers bodies includes clamping portions which have jaw parts. The jaw parts have curved edges thereon. The jaw part of the left pliers body corresponds to the jaw part of the right pliers body. The curved edges are adapted to lean against chain pins of chain plates to stabilize the operation of clamping.
