Title: Probe-correlated viewing of anatomical image data
Inventor: ZINREICH SIMION J
IPC: A61B34/20
Filed: 1989-11-21
Abstract: A computerized system for viewing of internal anatomical regions of a patient based on previously acquired image data of the patient.  The anatomical regions are viewed in direct relationship to a moving probe which can be hand-held.  The location of the probe relative to the patient is reported to computer.   The computer then uses the previously acquired image data to generate a desired view of the patient's anatomy in relationship to the position or orientation of the probe.   An operator is able to visualize normally invisible anatomical features before commencing, and during, procedure.  The correspondence between positions of the patient's anatomy is to locations on the stored data images is determined  through  an  initialization  procedure  which  can  be repeated or refined between viewing operations.  The system may be employed during diagnostic, therapeutic, or surgical procedures.

Patent CA-2263170-A1 (CA)
Title: Persistent heap for dynamic picture objects
Inventor: DOTY DOUGLAS E
IPC: G06F9/44
Filed: 1997-08-28
Abstract: There is provided a process control system having a display program that permits a program designer to create and edit dynamic picture objects in a persistent heap and save the heap to a storage medium. The display program rapidly reads the dynamic picture objects from the storage medium and invokes the objects for viewing on the system's interactive display. When the persistent heap is subsequently read from the storage medium by an operator, the dynamic picture objects stored in the heap do not need to be instantiated and, thus, invocation of the objects is accelerated and optimized. Accordingly, the persistent heap greatly improves the speed in which picture objects can be read from the storage medium, processed by the display program and called-up to the interactive display.

Patent CA-2269581-A1 (CA)
Inventor: PATEL NARENDRA D
IPC: G01N29/24
Filed: 1997-10-24
Abstract: An on-line ultrasonic sensor for monitoring and sensing failure in a cutting tool insert. The preferred embodiment of the sensor includes a piezoelectric film of aluminum nitride (AIN) deposited onto a tool insert or tool insert seat with the AIN film electrically connected to a signal generator and detection circuitry. A voltage pulse is applied to the AIN film to generate ultrasonic signal pulses in the AIN film which are transmitted through a tool insert to the vicinity of the cutting edge of the tool insert during use. Back-reflected ultrasonic signals from the edge of the tool insert induce a voltage signal in the piezoelectric film which is analysed and compared to signals characteristic of undamaged tool inserts. Temperature increases, wear and various types of tool failure can be readily detected during use of the insert with the sensor.

Abstract: A reclosable plastic bag comprises first and second opposing body panels, a zipper, a slider, and first and second upstanding panels. The opposing body panels are fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The zipper extends along a mouth formed opposite the bottom. The zipper includes a first track with a first profile and a second track with a second profile. The first and second profiles are releasably engageable to each other. The slider is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles are engaged to each other while the slider is in the closed position, and the first and second profiles are disengaged from each other in response to movement of the slider from the closed position to the open position. The first and second upstanding panels extend upwardly from the respective first and second body panels. Each of the upstanding panels includes opposing ends, and the opposing ends of the first upstanding panel are connected to the respective opposing ends of the second upstanding panel to form an open pocket in which the slider and zipper are captured. The open pocket may be sealed by joining the first and second upstanding panels to each other above the slider so as to completely encapsulate the slider within the pocket.

Title: Method and apparatus for retention of a refrigeration fluid in a refrigeration enclosure
Inventor: NOWOTARSKI MARK STEPHEN
IPC: F25D3/11
Filed: 1999-06-07
Abstract: The method of the invention is based on the comparison of local vapor concentrations at the inlet and outlet refrigeration ports and taking action based on that comparison. Control apparatus incorporating the invention is installed inside a refrigeration enclosure, adjacent to a port, preferably at the lowermost port. If the enclosure contains multiple ports at similar height, then each port has a form of the control apparatus attached to it. The control apparatus adjusts a flow of vapor leaving the interior of the enclosure. The control apparatus includes a duct assembly and a blower system. The bottom portion of the duct assembly is a tunnel enclosure through which a conveyor belt passes. Connected to an inside edge of the tunnel enclosure is a duct that extends upward from the conveyor belt. A blower for this duct either sucks vapor away from the conveyor belt or blows vapor from the enclosure interior toward the belt.      Regardless of the flow direction, a vapor curtain forms inside the tunnel enclosure and represents a transitional region from all vapor to all air. Control of the blower for the duct assembly is based on vapor concentrations in the tunnel enclosures adjacent to each port. A microprocessor compares measured concentration levels and alters the blower motor frequency in such a manner as to minimize the difference in concentration levels at each port.

Patent CA-2278498-A1 (CA)
Inventor: DOOLEY MICHAEL W
IPC: A61N1/37
Filed: 1998-01-16
Abstract: A current and temperature compensated voltage reference circuit operates from a power supply voltage as low as approximately 1.3 Volts. A current reference circuit uses a folded-cascode amplifier to measure the temperature dependent voltages provided by first and second bias circuits, each of which includes two series-coupled diodes or diode-connected bipolar junction transistors (BJTs), and provides a proportional to absolute temperature (PTAT) current in response thereto. A voltage reference circuit uses a PTAT current through a resistor to create a PTAT voltage in series with a diode-voltage, and the resistor value is adjusted until the sum of these voltages is approximately equal to the bandgap voltage of silicon, thereby providing a temperature compensated voltage reference. The reference circuit is suitable for use with an implantable cardiac rythm management system having a battery that provides a power supply voltage approximately between 1.3 Volts and 3.25 Volts.

Title: Current interrupter for electrochemical cells
Inventor: PINAULT ROBERT J
IPC: H01M50/574
Filed: 1998-04-08
Abstract: A current interrupt mechanism for electrochemical cells is disclosed. A  thermally activated current interrupt mechanism (38) is integrated into an end cap assembly (10) for an electromechanical cell. The thermally responsive mechanism (38) preferably includes a free floating bimetallic disk (40) or shape memory alloy member which deforms when exposed to elevated temperature causing a break in an electrical pathway within the end cap assembly. This prevents current from flowing through the cell and effectively shuts down an operating cell.
