Abstract: The method of the present invention defines a method in a computer system having a user interface, a memory, a repository and a database, and a repository program operating in the computer system for generically manipulating properties of objects stored in the repository. The program executes a method comprising the steps of determining if the current value of the property is known, and if not; determining if the current value of the property is needed, and if so; calling getProperty to retrieve the current value of the property; determining if the value of the property is to be changed, and if so; calling setProperty to alter the value of the property.

Abstract: A method of arranging and operating a multiprocessor computer server system having "split-transaction bus" architecture, including bus modules operating with an address phase and a cycle phase, and arranged for access by a prescribed resource stage, to facilitate "RETRY", this method including; providing a Cache Tag and Address Compare,arranging the system so that a first bus module stores the address for the Resource stage in the Cycle Tag; andcomparing subsequent address bus cycles to the contents of the Cache Tag so that, givena "match", a "RETRY" direction is responsively sent to any other bus module that requests access.

Abstract: The present invention operates in a file server having a peripheral storage subsystem coupled thereto by means of a fibre channel. The file server includes an apparatus disposed between the file server and the storage subsystem for adapting fibre channel transmissions to and from an industry standard data bus of the file server. The apparatus includes a microprocessor executing a method comprising the following steps. Sensing if an interrupt has occurred by the file server, and if so, determining the condition of the interrupt by the file server and handling it. If an interrupt has not occurred, testing an interface between the fibre channel and the apparatus to assure connectivity of the fibre channel. Next, sense for an action to be taken in response to the interrupt, and if so attempt to take appropriate action.

Abstract: An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.

Abstract: A "bit-sliced" construction cache module dictates dual TAG RAM Structures and dual invalidation queues, yielding enhanced performance: putting half the TAG array in each of two cache arrays, and allowing each to handle only one-half of the possible address values. Preferably, one half-module handles ZERO least-significant bits and the other handles ONE least-significant bits. Processor operations and invalidation operations can be "overlapped", and even operate simultaneously.

Abstract: A method and system for optimizing shift operations by reducing the computational overhead and the number of full scan path shifts associated with accessing and modifying data on a rotating scan path image are disclosed. The system further simplifies the construction of a scan path image by inserting a programmable number of leading and trailing bits around a selected string of data bits. The system manipulates and constructs a scan path image without having to shift or prepare the entire scan path image in memory. Specifically, the system comprises a master controller having a lead bypass module, a trail bypass module, a first shift module, a second shift module, a select module and a shift control module. Collectively, these modules comprise the necessary hardware for executing a plurality of shift optimization functions which include lead and trail bypass insertion, non-destructive read, field isolation, field insertion, bit order reversion, bit rotation and simultaneous read and write operation.

Abstract: An improved digital data modulator is provided for a digital transmitter. The digital data modulator comprises of a pair of digital data synthesizers which are controlled in a manner which produces complex conjugate modulated data signals of the input signals. Summing means are provided to sum the outputs of the digital data synthesizers in a manner which removes the imaginary components and simultaneously reduces the side load power without employing conventional filters.

Abstract: A novel interface unit circuit for connecting circuit card assemblies to a data stream and to each other is designed for implementation on a high speed semiconductor chip. A parallel bit data word comprising a programmable address field is compared to a mask address stored in buffer registers and in the presence of a match, the parallel bit data word is stored in a sink register. Also the address field of the data word is filled with zeros and passed to the output of the data channel where the time slot for the data word may be written over with new data words or the time slot passed on to other circuit card assemblies or other elements.

Abstract: A method which provides for controlling the ordering of document images in an image based document processing system so as to minimize the likelihood of an operator making an incorrect entry. In a particular preferred embodiment, transactions comprised of a single deposit ticket and a single check are reordered when displayed for amount entry so that they are separated by at least one document image. This minimizes data entry errors, since an operator cannot assume that successively displayed items are related.
