摘要:
A format converting and recording method and system for optical storage media including the steps of converting several first optical storage medium information files into the second optical storage medium through generating corresponding navigation tables which gather at a management file, transmitting image of the first optical storage medium to the second optical storage medium, and then generating a destination disc according to the management file. Thus, the operation process is simplified and the problem of lacking in playback control is solved.

A method and system for routing a multicast packet through a unicast packet switch network of devices. A virtual destination group, which includes destination devices of the multicast packet, is defined, and then the virtual destination group is mapped to an unused unicast destination encoding in routing tables of the devices. The multicast packet is then routed from a source device to the destination devices using the routing tables.

The present invention provides a fixing seat of main transmission shaft of a scanner, wherein a conical hole is formed on the surface of a main transmission shaft whereon a scanning head can move, and a belt conveyor is used to wind around a timing pulley and an idle pulley. The timing pulley is driven to rotate by a motor device so that the belt conveyor can drive the scanning head to move on the main transmission shaft. One end of an axis of the timing pulley protruding out of the surface thereof forms a slanting conical end, which is fixed in the conical hole. The present invention has the advantages of high stability, good reliability, and a low manufacturing cost.

A method of coding video pictures in a PB frames mode comprises the steps of: a) initializing a sum value; b) determining, for each block of a picture, a block motion vector, defining the block motion against the previous picture; c) computing a value indicating of the amount of each block motion vector and comparing each indicative value against a first predetermined threshold value; d) for each block motion vector, if the indicative value thereof exceeds said first predetermined threshold value, incrementing said sum value; e) if, after completing the comparison for all block motion vectors, said sum value exceeds a second predetermined threshold value, then; f) coding the video picture as comprising at least one P-picture, but no B-picture.

The present invention discloses a halftone processing of image and text auto detection, which is used to keep both the bit depth of images and the clarity of text when faxing or copying documents. The process of the present invention is stated as follows: choose the background color from the master copy, separate the content of the master copy into images and text with the chosen background color as the criterion, process the images with halftone processing, process the text with line art processing, and then output the processed images and processed text as a whole.

A method of fabricating a metal-oxide-semiconductor (MOS) transistor is provided. First, a patterned hard mask layer with an opening therein is formed over the substrate. A spacer is formed on the sidewall of the patterned hard mask layer in the opening. An isotropic etching process is performed on the substrate to form a recess in the substrate. An ion implant process is performed on the substrate in the lower portion of the recess using oxidation-restrained ions. The spacer is removed. Then, a thermal process is performed to form a gate oxide layer on the surface of the substrate within the recess such that the gate oxide layer in the upper portion of the recess is thicker than that in the lower portion of the recess.

A method and apparatus for out-of-order memory processing within an in-order processing device includes processing that allows a plurality of memory transactions to be processed in a pipeline manner until a dependency arises between two or more memory transactions. Such processing includes, for each of the plurality of memory transactions, determining whether data associated with the transaction is stored in local cache. If the data is stored in local cache, it is written into a data register in a next pipeline interval. The processing continues by storing the memory transaction in a miss buffer when the data associated with the memory transaction is not stored in the local cache. The processing continues by writing the associated data for the memory transaction identified in the missed buffer into the data register when the data is received without regard to the pipeline manner.
摘要:
A scanner providing the function of an automatic document feeder type scanner and the function of a platform type scanner which includes a platform housing, a lift cover pivoted to the platform housing, an automatic document feeder pivoted to the lift cover and having a feeding slot covered with a dust cover, and a selector switch turned between a platform scan mode and an automatic document feeder scan mode, wherein when the selector switch is switched to the automatic document feeder scan mode, the lift cover is disengaged from the automatic document feeder and the automatic document feeder is retained to the platform housing, permitting the dust cover to be lifted with the lift cover for feeding paper; when the selector switch is switched to the platform scan mode, the automatic document feeder is engaged with the lift cover and disengaged from the platform housing and can be lifted with the lift cover from the platform housing.
