Abstract: A flame-retardant epoxy resin composition includes on the basis of the total weight of the composition: 25˜65 wt % of epoxy resin, 16˜30 wt % of brominated epoxy resin, the brominated epoxy resin having a capping group selected from an epoxy group and a tribromophenol group, and 10˜25 wt % of organophosphorus flame retardant. The flame-retardant epoxy resin composition further relates to a method for preparing a composite material by vacuum infusion of the flame-retardant epoxy resin composition, and an article obtained by the method.

Abstract: A ball valve structure includes a valve body having a valve chamber therein. A valve ball is accommodated in the valve chamber. The valve ball defines a flow hole therein. Two gaskets are in close contact with two opposite side surfaces of the valve ball, so that the valve ball can rotate around a fixed point in the valve chamber. One side of one of the two gaskets abuts against a washer and a compression spring, so that the gasket is elastically pressed against a surface of the valve ball. A valve stem is connected to the valve ball through the valve body for driving the valve ball to rotate, enabling the flow hole to be opened.

Abstract: A detector circuit incudes a calculator circuit and a comparator circuit. The calculator circuit is configured to generate a plurality of first calculation values according to a plurality of first calculation symbols of a Pseudo-Noise Sequence and a plurality of second calculation symbols of a received signal, and generate a second calculation value according to the first calculation values. If a sign of a symbol of the Pseudo-Noise Sequence is the same to a sign of an adjacent symbol, the symbol is one of the first calculation symbols, and the second calculation symbols are corresponding to the first calculation symbols respectively. The comparator circuit is configured to generate a comparison result according to the second calculation value and a threshold value. The comparison result is configured for determining whether the detector circuit correctly receives the Pseudo-Noise Sequence.

Abstract: A plasma hydrogen generation device includes a liquid fuel storage bottle, an air filtering element, a large capacitor battery and a fuel cell power set. In operation, the carbon hydrogen compound is decomposed into hydrogen and carbon without carbon dioxide generation when a liquid carbon hydrogen compound is decomposed in the plasma hydrocarbon decomposition element. The produced hydrogen is directly provided to fuel cells on the car to generate electric power. As such, the resulting electric power may be directly used for the electric motor driving system on the car. Further, it is also suitable for a home electric power supply device with home or industry electricity specification, or used in combination with an electric vehicle (EV) car driving system to become a hydrogen hybrid EV car, or used in combination with a natural gas internal combustion engine to become a hydrogen hybrid car driving system.

Abstract: A decoding method for LDPC code includes steps of obtaining a set of parity-check matrices of a set of block codes; obtaining an identical parity-check matrix from the set of parity-check matrices; dividing the identical parity-check matrix into an odd identical parity-check matrix and an even identical parity-check matrix, wherein the odd identical parity-check matrix being composed of odd rows of the identical parity-check matrix, and the even identical parity-check matrix being composed of even rows of the identical parity-check matrix; and decoding the set of block codes basing on the odd identical parity-check matrix and the even identical parity-check matrix.

Abstract: A PCI Express link state management system and method thereof is disclosed. The PCI Express link state management system includes an upstream device, a downstream device and a link. The upstream device outputs a configuration request to the downstream device to change a device power state of the downstream device. At the time, the link is in a first link state. The downstream device outputs a power entering signal to the upstream device and counts a time period. The link enters to a recovery state and further then return to the first link state if the downstream device does not receive a power request acknowledging signal before the time period is expired.

Abstract: A PCI Express link state management system and method thereof is disclosed. The PCI Express link power state management system includes an upstream device, a downstream device and a link. First, the upstream device outputs a configuration request to the downstream device so as to change a device power state of the downstream device. At the time, the link is in a first link state. Next, the downstream device outputs a power entering signal to the upstream device. Following that, the upstream device outputs a power request acknowledging signal to the downstream device in response to the power entering signal and a time period is counting. Finally, the downstream device re-outputs the power entering signal if the link does not enter to an electrical idle state when the time period is expired.

Abstract: In a data buffer space configuration method for requesting data from a target device via a bus, a device count of master device coupled to the bus is detected by the operating system. Then, a first data buffer space is configured to the master device if the device count is not greater than a threshold. On the other hand, a second data buffer space is configured to the master device if the device count is greater than the threshold.
