Abstract: A system including a processor configured to perform generating a plurality of different layout blocks; selecting, among the plurality of layout blocks, layout blocks corresponding to a plurality of blocks in a floorplan of a circuit; combining the selected layout blocks in accordance with the floorplan into a layout of the circuit; and storing the layout of the circuit in a cell library or using the layout of the circuit to generate a layout for an integrated circuit (IC) containing the circuit. Each of the plurality of layout blocks satisfies predetermined design rules and includes at least one of a plurality of different first block options associated with a first layout feature, and at least one of a plurality of different second block options associated with a second layout feature different from the first layout feature.

Abstract: A set-top box device capable of providing electrical power to an antenna includes an insulation housing, a printed circuit board, a metal portion, and a conductive locking member. The insulation housing has at least one lateral arranged thereon a through hole portion. The printed circuit board is arranged in the insulation housing and includes a power supply module. The metal portion is arranged on the printed circuit board and includes a locking hole corresponding the through hole portion. The conductive locking member passes through the locking hole, the through hole portion, a conductive end portion of the power supply line, and the metal portion. The power supply module feeds a current into the antenna through a connection of the metal portion, the conductive locking member, and the conductive end portion, and the current flows to a ground portion of the signal line thereby forming a power supply loop.

Abstract: A method for reducing roughens of the metals on a ceramic substrate having metal filled via holes, comprising forming via holes, a seed layer, and through film coating, exposure and development process followed by multiple steps of DC electroplating to achieve copper circuit with desired surface roughness.

Abstract: A digital TV set-top box includes a casing, a fixing frame, an adapter board, a hard disk drive, and a sliding frame. The casing is provided with an opening, and the fixing frame is arranged with the hard disk drive. Since the sliding frame is smaller than the opening of the casing, the sliding frame can pass through the opening and be slidably arranged between two chutes of the fixing frame, and a connecting head of the hard disk drive can be correspondingly plugged into the adapter board so as to establish an electrical connection. As such, the present invention provides a TV set-top box that the hard disk drive can be assembled therewith or disassembled therefrom easily, so that the hard disk drive of the digital TV set-top box can be maintained or upgraded without the need of removing the whole upper casing of the set-top box.

Abstract: A projector comprises a light-emitting device for generating light beams, a reflector for focusing the light beams to a predetermined region, a light integrator positioned at the predetermined region and a brightness-adjusting module for adjusting the brightness of the projector by changing the relative distance of the reflector and the light integrator. Preferably, the reflector is an elliptical reflector having two foci, the light-emitting device is positioned at one of the two foci and the other focus is laid in the predetermined region. The present method for adjusting the brightness of a projector is characterized in adjusting the distance between the light integrator and the reflector to adjust the brightness of the projector.

Abstract: A heat-dissipating structure for switching an air direction is provided. The heat-dissipating structure for switching an air direction is used for dissipating the heat generated from a bulb according to one of an upright state and an inverse state of an apparatus provided with the heat-dissipating structure and having a body placing thereon the bulb, including: a wind-supply device and an air direction switching device. The wind-supply device is mounted in the body for supplying a wind flow to a first side of the bulb for dissipating heat along a first wind direction while the apparatus is at the upright state. The air direction switching device is mounted in the body and includes a guiding region for guiding the wind flow to a second opposite side of the bulb along a second wind direction while the apparatus is at the inverse state.
