Abstract: Data merge processing based on difference between source and merged data includes creating merged data from a source data records, the merged data including data fields, performing a difference determination as between the merged data and the source data records, the difference determination including, for each source data record of the source data records, comparison of data in data fields of the merged data to the source data record, and performing processing with respect to the merged data based on the difference determination. Performing processing can include aborting a merge operation to save a merged data record with the merged data, or storing and maintaining a merged data record including the merged data, based on the difference determination determining, for each source data record of the source data records, that the degree of difference between the merged data and the source data record does not exceed a threshold.

Abstract: A data storage library includes a drive enclosure bay which can be adapted to work with multiple air-flow configuration requirements. This is accomplished by creating air-flow ports in the top and bottom of the drive enclosure bay, by forming drive tray slots and printed circuit board ports in associated drive trays, by creating frame ports and PCB notches in associated interface cards, and replacing traditional connectors with slimmer but longer connectors that provide additional standoff and improved air-flow.

Abstract: An apparatus, system, and method are disclosed for integrating a blade RAID controller and storage. A storage blade enclosure communicates with a blade chassis. The storage blade enclosure is mounted within the blade chassis. A RAID controller disposed in the storage blade enclosure receives a command through the storage blade enclosure. In one embodiment, the command is communicated through the blade chassis from a processor blade mounted in the blade chassis. The RAID controller redundantly stores data to or retrieves data from a storage module disposed in the storage blade enclosure in response to the command using a RAID redundancy methodology.

Abstract: Disclosed is a method, system, and data structures for updating data in a storage device. An update to one or more blocks of customer data at addresses in the storage device is received. For each block of data to update, metadata is generated indicating the address of the block in the storage device and an error checking code that is capable of being used to determine whether the customer data in the block has changed. For each block of data to update, the block of data to update and the metadata for the block are written to cache. Further, for each block of data to update, the block of data and the metadata are transferred for the block from the cache to the storage device. The metadata may be used during power loss and recovery.

Abstract: Disclosed is a method, system, program, and data structures for transferring data to a requesting application. A request is received for one or more blocks of data at contiguous addresses in a storage device. Each block of data includes customer data and metadata indicating the address of the block in the storage device and an error checking code that is capable of being used to determine whether the customer data in the block has changed. For each requested block, a determination is made as to whether the address of the block of data in the metadata and the requested address match. Further, for each requested block, an operation is performed on the customer data in the block and the error checking code to determine whether the customer data has changed. The requested block is transferred to the requesting application if the address of the block in the metadata and requested address match and the customer data has not changed.

Abstract: There is disclosed a bar code reading device that can highly accurately read bar codes. Threshold values are established for correct identification of bar codes without being affected by blots on and unevenness of the bar code carrying surface and unstable maneuvering operations of the bar code reading device.

Abstract: A bar code reading apparatus for detecting the space between characters (the character space) by counting the number, which is a fixed number in the bar code, of edges, or transition points, of the bars and spaces for each character code, and either inhibits the count value by its bar/space width counter for the space beyond the fixed number of bars/spaces for one character (i.e., the count value for the character space) from being supplied to its decoder portion, or supplies the decoder portion with a specific code which the decoder will neglect in decoding, whereby the character space is prevented from adversely affecting the bar code reading.

Abstract: A bit image converter for composing a decoder for converting the value of counting clocks loaded in response to the width of bars or spaces for composing a bar code into character information of a code reader is composed of a module number calculator for calculating the magnification of the basic module from the number of the modules for composing one code unit (one character), a module number total comparator for comparing the total sum of the number of the calculated modules with a specified number n of the modules, a module number corrector for correcting, if the number of the calculated modules is less than the specified number n (n-1), it to the specified number n, and a bit image output unit. Thus, the code reader is adapted for a multilevel bar code system so composed that a result becomes correct information by correcting, if the number of modules for composing one character is less than a specified number n, it.

Abstract: A bar-code remote-control device includes a first key for inputting a detection instructing signal and a second key for inputting a transmission instructing signal. The device also includes a gate circuit which is opened after completion of a processing in a remote-control data transmission processing section to permit entrance of the detection instructing signal in a bar-code detection processing section and is closed upon completion of bar code detection processing in the bar-code detection processing section to prohibit entrance of the detection instructing signal in the detection processing section, so that no error occurs upon simultaneous operations against the first and second keys.
