Abstract:
The present invention discloses a rate matching method and device. The method includes that: an information bit sequence is coded and interleaved to obtain a mother code codeword with a length NFB—Buffer; and bits are selected from the mother code codeword to generate a hybrid automatic repeat request (HARQ) subpacket for current transmission. By means of the present invention, the effect of covering the whole mother code area can be achieved as much as possible, and the performance of the HARQ multiple retransmission link can be enhanced.
Abstract:
A method of image processing comprising receiving a plurality of interpolated images, interpolated from two adjacent camera positions having different image planes, applying a transformation to each interpolated image to a respective one of a plurality intermediate image planes, wherein each intermediate image plane is oriented intermediate to the image planes of the two adjacent camera positions depending on a viewing angle of that interpolated image relative to the adjacent camera positions. Also an integrated circuit or processor, an apparatus for capturing images and an apparatus for displaying images.
Abstract:
The present invention provides a helical slow-wave structure, including a helix, a metal barrel and several supporting rods. The plurality of supporting rods may be inserted into the lines of the grooves tightly, this increases the contact area between the helix and the plurality of supporting rods. With a proper assembly method, the thermal contact resistance between helix and supporting rod may be decreased. So, the invention may enhance the capability of transferring the heat out of the helical slow-wave structure. The helix may have higher heat capacity, therefore, the helical slow-wave structure may become more firm, and more reliable.
Abstract:
A method for processing Forward Error Correction, FEC, data, which includes: a sender encapsulates the FEC data to be a Transport Stream, TS, message, sets FEC identification information in the TS message, and encapsulates the TS message to be a Real-time Transport Protocol, RTP, message; then sends the RTP message to a terminal side. The reception end receives the RTP message; if the reception end has a function for FEC decoding, the reception end identifies the FEC data according to the FEC identification information in the TS message of the received RTP message, and recovers the missed media message according to the FEC data; if the reception end does not have the function for FEC decoding, the reception end processes the RTP message after removing the message header. The embodiments of the present invention also provide a transmission and processing device.

Abstract:
A system for actuating an engine valve to decompress an engine cylinder for engine start up and/or engine braking is disclosed. The system may include a first member, such as an outer piston, disposed above an engine valve, which receives an inner piston extending into a bore provided in the first member. One or more springs may bias the inner piston into a predefined position in the first member. The inner piston may include a lower surface that directly, or through an intervening sliding pin, actuates an engine valve in response to the application of fluid pressure on the inner piston. The inner piston may be used to decompress an engine cylinder for engine start up and/or to provide engine braking.
