Abstract: A video compression system includes a video encoder and a bitstream processing circuit. The video encoder is hardware that performs hardware video encoding upon frames to generate a first bitstream. The first bitstream is output from an entropy encoding circuit of the video encoder. The bitstream processing circuit performs a bitstream post-processing operation upon the first bitstream to produce a second bitstream that is different from the first bitstream, and outputs the second bitstream as a compression output of the frames.

Abstract: A video encoder has a processing circuit and a universal binary entropy (UBE) syntax encoder. The processing circuit processes pixel data of a video frame to generate encoding-related data, wherein the encoding-related data comprise at least quantized transform coefficients. The UBE syntax encoder processes a plurality of syntax elements to generate UBE syntax data. The encoding-related data are represented by the syntax elements. The processing circuit operates according to a video coding standard. The video coding standard supports arithmetic encoding. The UBE syntax data contain no arithmetic-encoded syntax data.

Abstract: A video encoding apparatus has a bitstream buffer and a first video encoder. The first video encoder sequentially encodes coding blocks of a first video frame segment in a first encoding order, and outputs encoded data of the coding blocks of the first video frame segment to the bitstream buffer. The first video frame segment is partitioned into a plurality of column tiles, each having at least one tile. The first encoding order is identical to an encoding order of encoding a video frame segment with only a single column tile.

Abstract: An apparatus and method for video encoding with low latency is disclosed. The apparatus comprises a video encoding module to encode input video data into compressed video data, one or more processing modules to provide the input video data to the video encoding module or to further process the compressed video data from the video encoding module, and one data memory associated with each processing module to store or to provide shared data between the video encoding module and each processing module. The encoding module and each processing module are configured to manage data access of one data memory by coordinating one of the video encoding module and one processing module to receive target shared data from one data memory after the target shared data from another of the video encoding module and one processing module are ready in said one data memory.

Abstract: A scanner has a hollow base, a bracket securely received in the hollow base and having a paper-pressing bar mounted onto the bracket, a top seat securely provided to one side of the hollow base and a top cover mounted on top of the top seat. The top cover has a pressing plate extending into an interior of the top seat and a pair of pressers each extending to engage with and abut the paper-pressing bar. The paper-pressing bar has a driven gear mounted on one distal end thereof so as to correspond to a driving gear of the bracket and a rubber sleeve mounted on the paper-pressing bar to increase a friction. The paper-pressing bar is releasably mounted on a pair of cutouts in the bracket so that the paper-pressing bar is able to move vertically relative to the bracket.

Abstract: A scanner has a motor, a transmission gear set coupled with the motor, a contact image sensor and a belt connected between the transmission gear set and the contact image sensor. A sensing assembly has a casing adapted to be mounted on a side of a screen and a sensor securely received inside the casing to initiate the motor such that the contact image sensor is also driven to scan.

Abstract: A scanner includes a casing defining an interior space in which an optic module movable in a longitudinal direction by means of a first transmission system is mounted. A carrier is arranged inside the casing below the optic module and is selectively movable out of the casing by means of a second transmission system. A tray supports an array of cells arranged in rows and columns for each receiving and retaining a biological sample to be scanned. The tray is movably mounted on the carrier and movable with respect to the carrier in a transverse direction by a third transmission system. The optic module is movable with respect to the sample cells in a line-by-line manner in the longitudinal direction, the tray being movable with respect to the optic module in a line-by-line manner in the transverse direction for covering a two-dimensional area in which the article is located.

Abstract: A micro ELISA reader includes a housing, a tray longitudinally movably provided in the housing, a carrier transversally movably mounted on the tray, a light source board provided on the carrier, and a scanning assembly longitudinally movably mounted in the housing and above the light source board. The ELISA reader is integrally installed in a personal computer. During a testing, a microtiter plate is stably positioned in the carrier and between the light source board and the scanning assembly, and scanned by the scanning assembly.

Abstract: A scanning device includes a body having an engaging recess so as to receive a PDA therein. A scanner is received in one of two ridges of the body an active shaft is connected to a side of the scanner and a first gear wheel is connected to an end of the active shaft. A second gear wheel is connected to the other side of the scanner and the first gear wheel and the second gear wheel are located at outside of the body of the scanning device. A transmission assembly is engaged with the first gear wheel and the second gear wheel. An optical sensing assembly is co-rotatably engaged with the transmission assembly so as to transfer the speed signal of the movement of the scanning device to the PDA to adjust the moving speed of scanning.
