Abstract: An improved storage method that maximizes efficiency and removes redundancy for a computing system maintaining a message handle system (MHS). For example, a MHS that is in accordance with the X.400 message handle system (MHS) standard. The X.400 MHS processes messages on a recipient basis, that is, the message is processed once for each recipient listed on a message. Such processing is inefficient and redundant, placing a toll on overall system processing. Such inefficiencies are even more apparent in the case of multiple recipient messages that require translation. In such event the message is translated and routed for each of the recipients listed. The improved storage system and method alleviates this redundancy and inefficiency. In the event a multiple recipient message requiring translation is routed over a X.400 MHS, the components of the X.400 MHS cooperate such that the message is translated, transferred, and stored in the X.400 MHS component requiring translated messages. The X.

Abstract: A document transport for moving documents past a document processing station utilizes a drive roller having a mass sufficient to provide a flywheel effect to stabilize speed of documents passing between the drive roller and a pinch belt in contact with a portion of the circumference of the drive wheel. The drive wheel may additionally have a circumference large enough to prevent document slippage between the drive wheel and the pinch belt.

Abstract: In a computer system having a memory and an operating system persistently stored in a storage device, a method for comparing System States of the system from time to time.

Next, the first collection of System State objects is stored in the memory. A second collection of System State objects, which was previously created and stored in the storage device, is then loaded into the memory. A comparison of the first collection with the second collection is made and an indicia of any differences therebetween is provided.

Abstract: A fiber optic channel loop provides a transmission path between a computer platform and a multiple number of peripheral devices. When any change occurs in the number of connected peripheral devices or their operation status, then Fiber Channel loop is interrupted so to disable ongoing Input/Output operations to a targeted peripheral device. When this interruption is sensed, the Master Control Program of the platform will institute corrective measures to re-originate any interrupted I/O operations.

Abstract: An integrated circuit tester includes a fail-safe mechanism for moving an integrated circuit chip between an initial position where the integrated circuit chip is inserted into the tester, and a test position where the integrated circuit chips is actually tested. This fail-safe mechanism includes a motor and a shaft which the motor rotates to move the integrated circuit chip. An electronic control circuit can be included to automatically stop the motor when the integrated circuit reaches its initial position, or its test position; but if the control circuit fails to operate properly, then damage to the integrated circuit tester is prevented by the fail-safe mechanism.

Abstract: A method of tracking a document in a system for feeding and transporting documents includes detecting a document trailing edge at a fixed location upstream of a feeder. The system includes a feeder stage and a transport stage downstream of the feeder stage. The feeder stage includes the feeder and a separator. The method further includes tracking a position of the document trailing edge as the document trailing edge moves between the fixed location and the feeder, and performing an operation dependent on the document trailing edge position when the document trailing edge is between the fixed location and the feeder.

Abstract: A method and an estimator program for estimating the optimum Server Farm size and the availability of the Server Farm for a given Redundancy Factor and a given particular number of clients.

Abstract: An initial stage of a multi-stage algorithmic pattern generator which generates bit streams for testing IC chips, is comprised of multiple sets of input registers which store respective addresses; and an address modifying circuit that is coupled to the input registers, which receives commands, and in response, selects one register in one set and generates a modified address by performing arithmetic operations on the address in the selected register. Also, the initial stage includes a boundary check circuit that is coupled to the address modifying circuit, which stores a respective minimum limit and a respective maximum limit for each register set. This initial stage is particularly useful in generating sequences of addresses for memory cells in a chip that is to be tested, where the cells are arranged in rows and columns. When a particular Min/Max limit for a row/column is reached, then that event is remembered by the boundary check circuit.

Abstract: A performance measurement tool is developed to measure performance of a terminal server servicing multiple Clients who operate on remote systems in a farm of multiple PC's. Test scripts to simulate actual operating conditions are run on each PC Client-User over a sequence of time which varies the number of concurrently active PC Client-Users from a small number of Users to a vary large number of current Users. During this test period, a record is kept of designated simulated-user-initiated actions such as log-on times, time to open various application programs, and character entries thus to determine acceptable operating configurations.

Abstract: In a system where a remote backup platform is enabled to automatically duplicate each registry key change in a local platform, a method is provided wherein restoration of original remote registry key data can be accomplished by utilizing a remote disk file which stores original data. When local original registry data on the local platform is lost to due breakdown, then a restoration program can access the backup remote registry key data for conveyance to the local registry key.

Abstract: The present invention provides a method and a computer system that compares a portion of a signal and information transferred from a cache memory, while the information is in transit from the cache memory. The information may be routed differently depending on the outcome of the compare. Specifically, the information may be delivered to a memory bus when it matches the portion of the signal and when the signal is a read command. Alternatively, the information may not be delivered to a memory bus when it matches the portion of the signal and when the signal is a write command. If the information does not match the portion of the signal, it may be transferred to a main memory via a memory bus. The information may be compared to the portion of the signal for a first time interval, and the portion of the signal may be compared to the information for a second time interval.

Abstract: A method of compressing image data utilizing CCITT Group 4 coding criteria reduces compression time and the amount of required data transfer by combining pixel data thresholding and transposition steps through the capabilities of a customized processing chip. Additional economies are achieved by using black/white and white/black transition pointers rather than the conventional approach requiring examination of every pixel to locate the transitions in preparation for conventional CCITT Group 4 encoding.

Abstract: A method of document overlap/gap error detection and correction includes detecting a trailing edge of a first document at a feeder, and detecting a leading edge of a second document at an edge detector between the feeder and a transport stage. An overlap/gap error is determined and the feeder is controlled to correct the overlap/gap error, when the error is present. An overlap may be measured before the first document trailing edge arrives at the edge detector, providing a greater remaining length of the second document left in the feeder with which to perform the necessary feeder motions to correct the overlap/gap error.

Abstract: A method and system provide for generating a predetermined feed spacing between a first document and a second document. The method includes the steps of determining an adjustment time period, and reducing a feed wheel speed to an adjustment speed. The feed wheel transports the documents between a document stack and a transport wheel. The method further provides for increasing the feed wheel speed after the adjustment time period has expired such that the trailing edge of the first document and the leading edge of the second document have the predetermined feed spacing. Determining the adjustment time period in conjunction with variable control of the feed wheel provides and enhanced approach to feed spacing unachievable through conventional approaches.

Abstract: A method is provided in a computer system executing a repository program and having a storage means for mapping alterations in system state to rules, both of which are part of an object-oriented model resident in a persistent repository. The method includes storing in the persistent storage means the model comprising a set of rules and a set of facts defining event states, both of which are stored as objects. The set of rules and said set of facts comprise an object-oriented representation of the model. Next, a set of commands representing an extensible inference engine are loaded as meta objects into the persistent storage. The method accepts as inputs events representing alterations in the set of facts. All of the events are retained and the events are mapped to the set of rules for deriving a list of affected rules, which are evaluated to determine if they have been qualified. Only those affected rules determined as qualified are saved for further processing.
