Abstract:
A system and method of using recursive cyclic redundancy check (CRC)+forward error correction (FEC) for enhancing the channel coding gain for a DVB-H receiver, and using a physical (PHY) Reed-Solomon (RS) decoder+FEC to achieve better coding gain. The system and method utilize a dual mode RS decoder (erasure mode and error mode) for FEC decoding. The PHY RS is used to provide smaller granularity for FEC. The system includes a cache memory management scheme for implementing the recursive CRC/RS+FEC in very large scale integrated circuit chip (VLSI) hardware.
Abstract:
A large resisting distortion combo-type bridge expansion joint, comprises fixed comb plate 2 and moveable comb plate 1 which are respectively disposed on the girder 10 where at the two sides of the bridge expansion joint, the moveable comb plate 1 has comb teeth 11 interdigitate with the comb teeth 21 of the fixed comb plate, characterized in that said moved comb plate 1 has a rotating shaft 8 the bottom of its second end, and the two ends of the rotating shaft 8 pivot in the shaft seat 7 which is directly or indirectly fixed on the girders 10. Compared with the prior art, this invention designs that around the second end of the moveable comb plate is rotatable, by which the moved comb plate will rotate round the girders when the girders have deflection distortion and the ends of the girders are raising or sinking. Therefore, the moved comb plate can keep flat to avoid damage of the expansion joint, and to ensure that the vehicle can pass safely and smoothly.

Abstract:
A system for permitting offline content playback and for managing the rights to one or more digital content files within a computer network. The system manages these rights by encrypting the content files to prevent unauthorized access to the files. Encryption is accomplished by using one or more keys which are associated with one or more segments of the content file. These keys enable an authorized user to decrypt and playback the content files at a subsequent time. When the keys are received, a license which specifies the rights of the user regarding the content files, is obtained by the end user system, and verified locally to permit the content playback.
Abstract:
A micro-electro-mechanical system (MEMS) microphone package is provided in the present disclosure. The MEMS microphone package includes a circuit board, an electromagnetic shielding cover mounted on the circuit board to define an accommodating space, electronic components received in the accommodating space and electrically connected to the circuit board, and a shielding ring covering a joint between the electromagnetic shielding cover and the circuit board. The shielding ring is configured for preventing electromagnetic waves from entering the accommodating space via the joint between the electromagnetic shielding cover and the circuit board.
