Patent CA-2017227-C (CA)
Title: Computer network for real time control with automatic fault identification and by pass
Inventor: MUTONE GIOACCHINO A
IPC: G05B9/03
Filed: 1990-05-22
Granted: 1994-12-13
Abstract: A computer network for real time control having redundant components for automated fault identification and automated bypass of identified faulty components.  The system includes at least two main computers, each coupled to at least two independent parallel data channels.  A plurality of satellite computer pairs are connected to these channels, each pair receiving information from a plurality of I/O racks which are connected to redundant sensors for detecting information and to redundant actuators for implementing system control.  The main computers are continuously cross-linked and perform evaluation of their respective input and output streams comparing these streams for consistency between the main computers.  In the event that an inconsistency is detected in the data streams, the system checks for faulty components to determine the origin of the inconsistency.  The system utilizes an evaluation method whereby each main computer independently accesses each of the parallel data channels, satellite computers, I/O racks, sensors and actuators to locate inconsistencies in the data stream. The system then allows for operation with one of the redundant components while the identified defective redundant component is repaired or replaced.

Title: Apparatus and method for reading, writing, and refreshing memory with direct virtual or physical access
Inventor: HORST ROBERT W
IPC: G06F12/10
Filed: 1990-06-29
Granted: 1996-08-27
Abstract: A computer memory system is provided.  Received memory requests can be for addresses which are virtual or physical.  The type of address is determined, and a virtual/physical bit is set and stored.  At least row address bits are compared to one or more registers which contain either a virtual or a physical row address, corresponding to a row addressed by a row address latch.    When there is a hit with respect to one of these registers, column address bits are used to select the requested memory element, without the necessity for a virtual-to-physical translation.  When there is a miss on all registers, a physical address is obtained, either from the requested address when this is physical, or from a virtual-to-physical translation.  The physical address is used to load a new row address into a row address latch.  Some column address bits are changed only when there has been a miss.  A refresh cycle is described, which includes reading back into a row address latch the same row address which occupied the row address latch before the refresh cycle, thus preserving locality information or structure.

Title: Superconductor sensors
Inventor: HOLLANDER MILTON B
IPC: G01R33/12
Filed: 1990-08-15
Granted: 1996-04-30
Abstract: A  superconducting wire is produced by the surrounding of  a  superconductive  material  core with an intermediate compressible  insulating layer and an outer malleable layer and  then drawing said composite structure through a series of  dies to reduce the diameter of the wire on the order of 400 to 10,000 times  or  by reducing the superconductive core  material  to  the desired  wire  size by passing it through  a  series  of  dies  to reduce the diameter of the wire  on  the order of 400 to 10,000 times and then coating the  wire  with a noncompressible insulating layer and then placing  an  outer  malleable layer over the insulated wire and  drawing  this  through  dies  to snuggly fit the outer layer    onto    the    insulated    wire.    This wire's superconducting characteristics   are  not  intended  for carrying  high  levels  of currents so the reduction of the available   current   carrying   cross   section   by   the introduction  of  the insulating layer is not of concern in the  applications  for  the  wire. Low and high temperature high  level  current-carrying  superconductors  lose  their superconductivity    with   changes   in   their   critical temperature   and  critical  magnetic  field.   A  loss  in superconductivity     in     a     high    current-carrying superconductor   can   cause   irreparable  damage  to  the superconductor   and   its   physical   environment.   Said superconducting  wire  when  used  in  assembly with a high current-carrying  superconductor   provides  a  means  for detecting  changes in the critical temperature and critical magnetic   field  of  the  current-carrying  superconductor before  the  superconducting  properties  are  lost so that measures can be  taken  to  correct  the  changes  in the critical temperature and the critical magnetic field.

Title: Digital signal quality evaluation circuit using synchronization patterns
Inventor: TARALLO JOSEPH A
IPC: H04L7/04
Filed: 1990-08-21
Granted: 1995-01-17
Abstract: DIGITAL SIGNAL QUALITY EVALUATION CIRCUIT    USING SYNCHRONIZATION PATTERNS Abstract In evaluating the quality of received digital signals in terminals of a mobile communication system, the bit error rate is measured. Each station receives signals in successive data frames which includes a synchronization pattern and stores a version of the synchronization pattern. The received sybchronization pattern is compared to the stored synchronization pattern to derive a signal representative of the received signal quality. The quality signal may then be used for hand-off toother base stations or other call transfers. Since the synchronization pattern is included in each data frame, measuring signal quality therefrom obviates the need for system generation and interpretation of special quality messages.

Granted: 2000-10-24
Abstract: A manual operator which is useful when used with a valve or other type of device to provide either manual operation of the valve in one direction or to provide a stop against the movement of the valve away from one of its extreme positions. The device includes a ball nut, screw shaft and balls positioned in facing grooves in the nut and shaft so that relative rotation has very low friction. Thus rotation of one of the nut or screw shaft results in axial movement of the screw shaft so that it can move or provide a stop.      Aligned adjacent exterior surfaces are provided on a rotating part of the device and one a stationary part of the device which surfaces are engaged by a locking spring which can be release from such surfaces when it is desired that the manual operator cause an axial movement of screw shaft. In one form of the invention the screw shaft rotates and the ball nut is stationery. In another form the ball nut rotates and the screw shaft is stationary. In a third form two locking springs are provided to lock against inadvertent relative rotation in both directions. In still another form of the apparatus, it is applied to a blowout preventer ram tail rod so that the axial movement of the tail rod is translated into rotation of a ball nut and a spring engages a surface rotating with the ball nut and a stationary aligned surface to prevent relative rotation in one direction to lock the tail rod with the piston in its inner or ram closed position.

Title: Surgical fluid evacuation system
Inventor: MCCARVER STACEY GERALD
IPC: A61B19/08
Filed: 1992-06-05
Granted: 2002-10-01
Abstract: Disclosed herein is a fluid evacuation system which is particularly well-suited for removing liquids from the site of a surgical procedure. In one configuration the system is in the form of a pad which can be placed directly on a patient or used in conjunction with a surgical drape. The pad is connected to a vacuum source and as fluids flow across the top surface of the pad, they are drawn down into a fluid receiving chamber and then removed via a suction line. As a result, fluids present during a surgical procedure are taken completely away from the operating site. In another configuration, the system is in the form of a suction rail which operates in the same fashion but can be molded or formed into a particular shape and then attached to a surgical drape in the expected path of fluid run-off.
