Abstract: Disclosed are a system, a method, and an article of manufacture to provide for the detection and compensation of tape breakage in a tape drive. The invention operates by simultaneously monitoring the tape reel rotation direction and the ratio of rotation between the tape reels. If the rotation direction is not the same for both reels, then tape breakage is indicated and reel rotation ceases. Tape breakage is also detected if the tape reel angular rotation ratio between the supply and take up reels is not within a specified tape reel ratio range. The tape reel angular rotation ratio is detected by simultaneously measuring the angular rotation of each tape reel in a specified time period and then calculating the ratio. The present invention detects the tape reel angular rotation ratio and if tape reel angular rotation ratio is outside of the specified tape reel ratio range, tape breakage is indicated and reel rotation ceases.

Abstract: In a tape having separate servo bands of patterns positioned laterally across the tape, the patterns of a separate servo band have at least one differentiating characteristic with respect to patterns of another of the separate servo bands. The differentiating characteristic allows identification of the separate servo bands. For example, the patterns of a separate servo band have differing azimuthal orientations of detectable transitions with respect to another servo band, such as being laterally inverted. In another, variations in the width of gaps of patterns are made with respect to another servo band. In another, variations are made in the number of the detectable transitions of patterns with respect to the patterns of another servo band.

Abstract: An in-vehicle hand-free apparatus that is for ensuring hand-free talk by a short-range wireless communication system in compliance with the Bluetooth includes a notification unit which notifies the status of the in-vehicle hand-free apparatus. As the in-vehicle hand-free apparatus notifies the status thereof by the notification unit, the user can easily perceive the status of the in-vehicle hand-free apparatus.

Abstract: A video platform architecture for video processing includes complex video compression/decompression algorithms in a computer with a two-dimensional Single-Instruction Multiple-Data (SIMD) array architecture. The video platform architecture includes one or more video processing modules, on-chip shared memory, and a general-purpose RISC central processing unit CPU used as a system controller. Each video processing module includes a rectangular array of processing elements (PEs), a block load/store unit, a global-accumulation unit. Video to be processed is configured into blocks of data, and a general-purpose CPU used as a local controller. A plurality of registers are provided in the processing elements and the block load/store unit to support two-dimensional processing of the data blocks. Types of registers used include block registers, vector registers, scalar registers, and exchange registers. Each of these registers is designed to hold a short ordered one- or two-dimensional set of video data (data blocks).

Abstract: A video platform architecture provides video processing using parallel vector processing. The video platform architecture includes a plurality of video processing modules, each module including a plurality of processing elements (PEs). Each PE provides parallel vector processing. Specifically, means are provided to read all elements of one or two source vector registers in each PE simultaneously, process the read elements by a set of arithmetic-logical units (ALUs), and write back all results to one of the vector registers, all of which occurs in one PE cycle. To provide such parallel vector processing capabilities, the datapath of each PE is built as a set of identical PE processing slices, each of which includes an integer arithmetic-logical unit (ALU), a vector register bank, and a block register bank. A block/vector register bank holds all I elements of row J in a two-dimensional I×J data blocks for all block/vector registers provided by the architecture.

Abstract: A method and system for rewriting data on a tape when an error occurs during an initial write operation. When the initial write error occurs, the data is rewritten at a location that is a pre-defined block gap distance from the last valid write location on the tape. By measuring the length of the pre-defined block gap distance, the cause or causes of the write error or errors are known. Thus, the pre-defined block gap not only ensures that the data is not re-written in a no-write zone of the tape, due to the zone known to be error prone, but a historical record of past write errors is logged based on the length of the block gaps.
