Title: Method and apparatus for detecting bad frames of information in a communication system
Inventor: WOOD SANDRA L
IPC: H04B14/04
Filed: 1994-07-19
Abstract: A communication system implements detection of bad frames of information by utilizing multiple bit correction thresholds. Equipment used within the communication system adapts to different signaling environments by dynamically altering the bit correction threshold based on a history of the number of consecutive bad frames of information that have been previously erased and the number of bits corrected by a channel decoder (202). By implementing this dynamic bit correction threshold, sufficent bad frame indication (BFI) detection and receiver sensitivity can be obtained simultaneously, which results in an improved perceived audio quality to the end user.

Abstract: To measure the level of contents in metallic tanks by means of short electromagnetic waves, it is proposed to mount the complete level measuring assembly, including the horn antenna, outside the tank. The transmitted waves are projected through an opening in the tank wall toward the surface of the medium whose level is to be measured. The opening is closed with a glass or ceramic plate. To distinguish the useful signal within the unwanted echos caused by multiple reflections of the electromagnetic waves at the glass or ceramic plate, a damping layer of a conventional damping material is interposed between the microwave coupling element and the surface of the glass or ceramic plate. To achieve an optimum signal-to-noise ratio, the damping coefficient is fixable and the distance between the level measuring assembly and the surface of the glass or ceramic plate is adjustable in the axial direction of the opening.

Inventor: GRACE ANDREW
IPC: H04L12/24
Filed: 1994-02-22
Abstract: Simultaneous events reported to an equipment management system are compared with historical data in order to establish whether there is a relationship between the events. Historical data is used to determine the statistical probability of the events occurring independently simultaneously.  If this probability is below a predetermined threshold this will suggest that the events are not independent, but are related. Such relationships are alerted to an operator, for example by highlighting or grouping on a screen display, assisting the operator in identification of related events, without the need for prior knowledge of the relationship in the system. The events may be alarms generated by faults in a network. The identification of related faults at different points in the network assists identification of their common cause. The historical database may be updated by further event occurrences as they are reported to the equipment management system, thereby enlarging the database to make the results more statistically accurate. Events may be reported to the system automatically or by human agency. To allow for systematic delays in event reporting, alarms from one source may be compared with alarms from another source occurring a fixed time later or earlier.

Title: One piece gasket for complex oil pan configuration
Inventor: GACIOCH THOMAS D
IPC: F01M11/00
Filed: 1995-09-01
Abstract: An improved gasket is designed for use on a complex interface surface between an oil pan and an engine. The gasket is formed as a one-piece molded part and is preferably injection molded from a silicone rubber. The gasket incorporates crush limiters at each bolt hole, and dual spaced sealing beads along the sides, with a circular sealing bead surrounding each bolt hole. The crush limiters control the amount of tightening of the bolts, while the sealing beads accommodate warpage of the oil pan, or undertightening of the bolt. In other features, tabs are disposed on each side of the gasket to accommodate an oil dip stick. The user of the gasket merely removes a cutaway portion associated with one of the tabs to provide a space for passage of the oil dip stick on the appropriate side. In this way, a single gasket can be incorporated into engine configurations having dip sticks on either side. In addition, an end tab is formed on one end of the gasket, and provides a saddle to be positioned outwardly of the engine to properly position the gasket.

Abstract: A method of evaluating bone density around a radiolucent composite prosthesis (27) establishes an implant boundary (118, 124) by fitting a stored template to radio-opaque reference markers (31) embedded in the prosthesis. The implant boundary is used to create a measurement boundary (126) displaced from the implant boundary toward the bone (26) producing a conformal region of interest. Matched histograms (130) of bone density in a lateral and medial region of interest may be displayed to evaluate symmetrical stress defects.  Alternatively, bone density may be displayed plotted along an axis (132) cutting across the medial and lateral sides. Fiducial points (100, 102, 104, 106, 108, 110) are identified from the bone and implant morphology to ensure that either display will have a repeatable reference, and hence that such displays will be directly comparable to later and earlier displays thereby aiding in the detection of bone change.

Title: Arbiter organization for serial bus transfers
Inventor: WOOTEN DAVID R
IPC: H04L12/28
Filed: 1995-11-21
Abstract: A serial bus host controller arbiter which organizes data transfer events into three categories, periodic data transfers, which are usually isochronous transfers; aperiodic transfers, which usually are asynchronous transfers; and control transfers.  The arbiter fundamentally operates on a periodic basis.  At the beginning of each period, the arbiter preferably alternates between periodic transfers and control transfers.  When all of the periodic transfers have been completed, the arbiter then provides access to the various asynchronous transfers which are scheduled to occur, alternating with any remaining control transfers.  The arbiter gives preference to the periodic events, and if any time within the period is available, which is referred to as the free time, control events are interleaved with periodic events until no free time remains or all are completed.  Any remaining time in the period is used cycling through the aperiodic transfers.  The arbiter of the preferred embodiment keeps a running total of free time during each period to determine if additional control or aperiodic transfers can occur.

Title: Seek actuator for optical recording
Inventor: GRASSENS LEONARDUS JOHANNES
IPC: G11B7/135
Filed: 1996-03-06
Abstract: An assembly for controlling the position of a lens in an optical data storage and retrieval drive includes a carriage that suspends a lens holder using a plurality of flexures. A lens is mounted in the lens holder such that the center of mass of the suspended lens holder lies on the optical axis of the lens, and also coincides with the center of mass of the lens. The lens holder is capable of relative motion with respect to the carriage with at least one degree of freedom. The center of mass of the carriage lies within 0.1 mm of the optical axis, proximate the center of mass of the lens holder. Suspensory forces acting on the lens holder are symmetric about the optical axis. A coarse magnetic drive moves the carriage in a tracking direction, and exerts forces on the carriage that are balanced and symmetric about the optical axis, so that moments about the center of mass of the carriage are effectively absent. Inertial forces acting on the carriage, and forces reactive to the magnetic drive forces are also balanced and symmetric with respect to the optical axis, and produce insubstantial moments about the center of mass of the carriage. There is a fine tracking and a focusing drive for the lens holder. Both of these drives produce balanced and symmetric forces about the optical axis, such that moments about the optical axis are absent. Inertial forces and reactive forces acting on the suspended lens holder are also symmetric about the optical axis. As a result the objective lens moves along its optical axis, and in its tracking direction without change in attitude, and its focal point can be precisely controlled with respect to the surface of a storage medium being read or written.
