Patent CA-2194569-A1 (CA)
Title: Ionizing radiation detector
Inventor: HASSARD JOHN FRANCIS
IPC: G01T3/08
Filed: 1995-07-21
Abstract: An ionizing radiation detector comprises a flat substrate (30) having a plurality of etched parallel ridges (40) on one surface. The parallel sides of the ridges carry a thin layer of a conducting material, acting as an electrode (50, 60) A particle or radiation beam (70) to be detected impinges on the ridges (40) in a direction normal to the plane of the substrate, so causing electron/hole carriers production within the ridges (40). The carriers migrate to the electrodes (50, 60) in a direction perpendicular to the beam (70) thereby inducing charge on the electrodes. The readout can be extremely rapid, since the carriers need to migrate only a very small distance to the side of the ridge.

Patent CA-2202210-A1 (CA)
Title: Inclined separation tank
Inventor: KOMISTEK STEPHEN MICHAEL
IPC: B01D17/00
Filed: 1997-04-09
Abstract: A vessel designed to separate out clean water from produced oil is disclosed. Conventional free water knockout vessels (FWKO) are normally disposed horizontally, and have a large diameter. The large diameter maximizes the distances between the oil/water interface and the exit points on the vessel for the water and the emulsion. The larger the vertical distance from the oil/water interface, the greater the chance that the oil and water can be agitated by slugs of gas and fluids. Tilting the vessel and reducing the diameter minimizes the distance the fluid has to travel to reach the top and bottom walls of the vessel, maximizes the distances from the oil/water interface, utilizes more fluid space in the vessel, reduces agitation caused by gas slugs, and forces the water to travel a longer distance which provides more separation time.

Title: Variable-incline ramp system for horizontal vehicle
Inventor: WALTERS LORNE
IPC: B66B9/08
Filed: 1997-04-16
Abstract: A variable-incline ramp system guides a vehicle through the incline between a first site and a second site while at all times maintaining the vehicle in its natural horizontal orientation. The ramp system includes a separate set of rails for guiding the front and the rear of the vehicle. In profile, the two sets of rails form a parallelogram having one pair of sides of a length equal to the wheelbase of the vehicle. So long as these parallelogram sides are horizontally oriented, the vehicle travelling along the rails will maintain its normal orientation because its wheelbase axis will be parallel to the horizontal sides of the parallelogram. In one embodiment suited for use in marine settings, the rails are movably connected to the first and second sites such that as the site elevations change, the parallelogram is free to skew while still remaining a parallelogram with the same length sides.

Title: Method for generating non-visible window edges in image compositing systems
Inventor: VLAHOS PAUL
IPC: G06T3/00

Abstract: The invention is a method used with a system for compositing a foreground scene including a subject before a nonuniformly illuminated colored backing, and a background scene, and where the nonuniformity is nonlinear from side to side and/or nonlinear from top to bottom. A window is employed to mask unwanted areas outside of, or on, the colored backing and one or more window edges form a visible join line where the window edges join the backing. The visible join line is made nonvisible without affecting the subject by a horizontal and vertical linear interpolation method for obtaining backing corrections that cause the backing level control signal to be uniform at the window edges and match an assigned window signal level.

Abstract: In the algometry management method and system, a computer apparatus is used to select points of a patient's body on which pain sensitivity pressure measurements have to be made, to determine a sequence of these selected points, and to indicate the selected points one by one to an operator according to the sequence.    A pressure  algometer  is  used  by  the operator to apply pressure  to each point  of  the sequence indicated and to measure the pressure being applied when a patient's threshold of pain is reached, this  pressure  measurement  constituting  a  pain sensitivity  pressure  measurement.    The  computer apparatus also receives the pain sensitivity pressure measurement from the algometer for each point of the sequence,  and stores the received pain sensitivity pressure measurements in a file associated to the patient.   The method and system also ask to the patient a subjective indication of the intensity of pain and degree of discomfort he felt upon application of pressure to each point of the patient's body.  A visual analog scale unit is provided to allow the patient to give this subjective indication of the intensity of pain and degree of discomfort he felt.
