  • Patent number: 6722019
    Abstract: A horizontal combined head is provided which has both a thin film write and an MR read element located at an air bearing surface (ABS). The read element can be formed with a track width that is independent of the track width of the write element. The MR sensor or the read element is separated from one of the first and second pole pieces of the write element by an insulation layer. Accordingly, the shields for the read element remain more stable after a write operation. In one embodiment of the present invention a single stripe MR sensor is employed while in a second embodiment a dual stripe MR sensor is employed. A method of the invention includes forming the dual MR stripe in a single process step so that the dual MR stripes of the dual MR sensor are near identical for implementing near absolute common mode rejection of noise.

  • Patent number: 6453325
    Abstract: In a database system with linkage between data in the database system and files in a system for filing data which is external to the database system (“the filing system”), backup and restoration of the database are coordinated with the filing system. Backup of a referenced file is initiated when the file is linked to the database system. The file backup is asynchronous to the linking process. When database backup occurs, all unfinished file backups are accelerated and completed before the database backup is declared successful. When a database is restored to a state with reference to files in a file manager, the database system causes the file manager to ensure that referenced files are linked to the database system.

  • Patent number: 6304866
    Abstract: In a multiprocessing system, multiple concurrently operating task execution units are operated to perform an aggregate task by using incremental and on-demand sub-task allocation. A command is received to perform a machine-executed task divisible into multiple sub-tasks, i.e., an “aggregate task”. A granularity is then established, for dividing the aggregate task into sub-tasks. Preferably, the granularity is not too large to permit potentially uneven sub-task allocation, and not too small to incur excessive overhead in allocating sub-tasks. Having established the granularity, multiple task execution units are independently operated on-demand to sequentially self-allocate and execute sub-tasks of the aggregate tasks. Each sub-task is sized according to the established granularity. Operating “on-demand”, each task execution unit sequentially allocates and executes one sub-task at a time, then proceeding to the next unexecuted sub-task.

  • Patent number: 6279128
    Abstract: A system for continuous monitoring and autonomous detection of patterns in the main memory subsystem of a computer system. The invention can be embodied as an extension to existing memory scrubbing hardware to permit stored code pattern analysis and identification during the autonomous transparent memory scrubbing process. A library of stored target signatures is provided to which code signatures are compared during analysis. Code signatures may be derived directly from the memory subsystem data pattern or may be indirectly and more efficiently derived from the error correction code (ECC) string associated with the stored data pattern. This invention is directly applicable to computer virus detection and neutralization systems.

  • Patent number: 6275031
    Abstract: Apparatus for quantitatively measuring groups of magnetic particles. The particles are complexed with substances to be determined and are excited in a magnetic field. The magnetic particles are thereby caused to oscillate at the excitation frequency in the manner of a dipole to create their own fields. These fields are inductively coupled to sensing coils fabricated in a gradiometer configuration. The output signals from the sensing coils are appropriately amplified and processed to provide useful output indications.

  • Patent number: 6272256
    Abstract: A method and apparatus incorporating a binary function correlation of run edges for compressing periodic halftoned digital images while increasing compression ratios over currently known one- and two-dimensional and adaptive arithmetic methods and decreasing the time required to perform the operation. In one embodiment, the invention horizontally encodes an image's run edges located at or near least &tgr; pixels ahead of a reference run edge in raster sequential image data. After the image is divided into lines of digital bits containing digital information indicative of binary values, the lines are encoded. A value for &tgr;—where &tgr; is independent of the width of the image and represents the periodicity for an edge of a run—is selected. Thereafter, run edges located &tgr;±n pixels ahead of a designated run edge of a reference run are encoded.

  • Patent number: 6266708
    Abstract: A framework for use with object-oriented programming systems includes one or more objects of a class called “Socket” that receive and process packets of work. As various applications execute, they require servicing of tasks, which correspond to the packets of work mentioned above. The packets of work are represented in the framework by objects of a class called “WorkUnit”. When a WorkUnit object is generated by an application, it in turn generates an object of a class called “Retriever” which is associated with the appropriate Socket object needed for servicing the WorkUnit. The Retriever object retrieves the Socket object to service the WorkUnit from an object of a class called “SessionInfo”. The SessionInfo object is a single object for maintaining registries of Socket objects and objects of a class called “ApplicationInfo”.

  • Patent number: 6256408
    Abstract: An automated optical character recognition method is provided for use in conjunction with a programmable digital processing device. The method inputs a sequence of values representing one or more characters in an array of characters to be optically recognized. The values define one or more dimensional characteristics of the characters. From the input values, a standard dimensional value is determined from a frequency distribution of a selected one of the character dimensional characteristics. For each of the input characters, a set of normalized values is determined from the standard dimensional value. The normalized values correspond to the one or more character dimensional characteristics. Optical character recognition is thereafter performed using the normalized values.

  • Patent number: 6210401
    Abstract: A laser-based method and apparatus for corneal surgery. The present invention is intended to be applied primarily to ablate organic materials, and human cornea in particular. The invention uses a laser source which has the characteristics of providing a shallow ablation depth (0.2 microns or less per laser pulse), and a low ablation energy density threshold (less than or equal to about 10 mJ/cm2), to achieve optically smooth ablated corneal surfaces. The preferred laser includes a laser emitting approximately 100-50,000 laser pulses per second, with a wave-length of about 198-300 nm and a pulse duration of about 1-5,000 picoseconds. Each laser pulse is directed by a highly controllable laser scanning system. Described is a method of distributing laser pulses and the energy deposited on a target surface such that surface roughness is controlled within a specific range.

  • Patent number: RE37242
    Abstract: A frame, a drive mechanism for rotating a mandrel, at least two spindles mounted to the frame, a tensioner, and a belt extending between the first and second spindles may be used to roll pre-preg strips or similar sheets of composite materials around the mandrel. The belt over the spindles, and the spindles guide the belt through changes in its direction of travel. The mandrel is mounted in the drive mechanism in contact with the belt, which changes its direction of travel around the mandrel. The lower surface of the belt bears against portions of the spindles, and the mandrel contacts the upper surface of the belt. As the drive mechanism rotates the mandrel, pre-preg sheets are fed between the mandrel and the belt and are thereby wrapped around the mandrel. The belt presses the pre-preg sheets against the mandrel. The wrapped mandrel may then be removed from the apparatus and cured in any suitable manner known in the art to produce a composite tubular article.
