    摘要: A method of mounting a volume from a tape medium on a tape drive apparatus. The method reads a bar-code indicating the volume from a tape cartridge, attaches the tape cartridge to a tape drive, and detects the current track position on the basis of a longitudinal track. The method then determines whether a beginning volume label or a last used area volume label is nearer to the current track position, reads the nearer volume label from the tape medium, confirms the volume by comparing the nearer volume label with the bar-code, and mounts the volume onto the tape drive.

    摘要: Video signal processing apparatus in which at least two input video signals are combined in proportions determined by a pixel key signal to generate an output video signal for compression, at least one of the input video signals each having respective associated compression parameters from a data compression process applied to that video signal. The apparatus functions to estimate the quantity of data which will be produced by compression of a current image of the output video signal, compares the detected quantify of data with a target quantity of data, to determine whether a data overflow is expected, and in the event that a data overflow is expected, determine which blocks of the output video signal can be compressed by re-using compression parameters from corresponding block of one of the input video signals.

    摘要: A system and method modifying wavefront shape is provided. Generally, the system contains a wavefront shape modifying device for modifying the shape of the wavefront. The system also contains a series of optical devices for returning the modified wavefront to the wavefront modifying device with an orientation that enables further modification of the modified wavefront by the wavefront modifying device. The method contains the steps of: reflecting a wavefront from a surface of a wavefront shape modifying device, resulting in the wavefront having a modified shape; and reflecting the wavefront having a modified shape from the surface of the wavefront shape modifying device a second time resulting in a final wavefront having a shape that has been modified twice.

    摘要: A method and apparatus for making carbon/carbon composite disks for braking applications that employs a continuous feeding of fiber strands into a mold. The fibers are then compressed to form a mat or preform. The fibers are then needled such that the fibers within the mat interlock and extend in various directions. The mat or preform is then subjected to densification processing. In order to enhance the effectiveness of the densification process and/or to speed up the processing time, a filler is added to the preform during the manufacturing process. The fillers are added by way of a dry powder or as a liquid slurry. The filler may be aluminum oxide, boron carbide, silicon carbide, pitch, or a variety of carbonic or noncarbonic performance enhancers.
