Abstract: A matte film for hot pressing and a manufacturing method thereof are provided. The manufacturing method includes steps of forming at least one polyester composition into an unstretched polyester thick film and stretching the unstretched polyester thick film in a machine direction (MD) and a transverse direction (TD). The polyester composition includes 81% to 97.9497% by weight of a polyester resin, 0.02% to 2% by weight of an antioxidative ingredient, 0.0003% to 1% by weight of a nucleating agent, 0.01% to 2% by weight of a flow aid, 0.01% to 2% by weight of a polyester modifier, 0.01% to 2% by weight of an inorganic filler, and 2% to 10% by weight of silica particles. The polyester resin has an intrinsic viscosity between 0.60 dl/g and 0.80 dl/g.

Abstract: A knob structure and an electronic device thereof are disclosed. The knob structure is assembled with a case of the electronic device and includes a plurality of pressing portions, an elastic component, and a fixing component. At least one pressing portion has a pressing rib used for pressing a switch module. The elastic component includes a main body and a plurality of elastic ribs. The plurality of elastic rib is disposed on the main body to support the pressing portion. When the pressing portion is pressed along a supporting direction, the elastic rib is capable of providing an elastic force. The fixing component includes a first end and a second end, wherein the first end connects to at least one of the plurality of pressing portions and the second end is extended along a direction different from the supporting direction and fixed to the case.

Abstract: A controller and a method of updating parameters on the same. The controller includes an embedded non-volatile memory, a programming circuit, an embedded SRAM, a MCU (Micro Computer Unit), and a memory controller. The embedded non-volatile memory has a program code block for storing program codes to be executed by the MCU, and a data block for storing the parameters. The MCU writes the parameters into the data block of the flash memory through the memory controller, or reads data in the data block of the non-volatile memory through the memory controller. Because the controller does not need to employ an external EEPROM, the cost can be reduced and the speed for accessing the parameters can be increased.

Abstract: A counterbalanced blind has a top frame, a bottom bar, a shade mounted between the top frame and the bottom bar, a reel device, two roller devices and two cords. The reel device is mounted in the top frame, and the two roller devices are mounted on the opposite side of the reel device in the top frame. The cords are wound and fastened in the reel device, respectively extend in opposite directions to the roller devices, pass downward through the shade and are fastened on the bottom bar. The bottom bar can be raised or lowered and position of the bottom bar will be retained after releasing the bottom bar.

Abstract: A system for programming at least a controller chip is disclosed. The system includes a programming apparatus and at least a programmable device mounted on the programming apparatus. The programming apparatus has at least a first connection interface and a micro-controller. The programmable device has the monitor controller chip mounted thereon and a second connection interface coupled between the first connection interface and the controller chip. The micro-controller controls the programming of the controller chip.

Abstract: A retractable window shade with multiple shading gradations has a guide rail, two shade bodies and two cord assemblies. The guide rail has two one-way arresting mechanisms. The two shade bodies have different opacities and each shade body has a top side mounted on the guide rail and a lower section. The cord assembles are respectively mounted through the one-way arresting mechanism and connected to the lower sections of the of the shade bodies. The cord assemblies are pulled to rise the lower sections of the shade bodies. When the force for pulling one shade body is released, the cords are selectively arrested by the one-way arresting mechanisms to hold the shade body in a proper position. By expanding both of, one of or none of the shade bodies, the retractable window shade provides a proper proportion of shading sunlight with appropriate, comfortable and mild brightness.

Abstract: A curtain rod support includes a bracket having a top plate, securing holes and an extension extending downward from a bottom face of the top plate, a hook having positioning holes aligned with the securing holes in the top plate to allow two bolts to extend through the aligned securing holes and the positioning holes to secure engagement between the bracket and the hook and a bend formed on a distal end thereof receivable therein a first curtain rod and a base having two arms extending upward from a base and a connecting hole defined through the base so that a second threaded rod is extended through the connecting hole and into the extension to secure engagement between the seat and the bracket such that a second curtain rod is receivable inside a receiving space between the base and a bottom face of the hook.
