Patent CA-2223756-C (CA)
Title: Light beam range finder
Inventor: MCEWAN THOMAS E
IPC: G01S13/00
Filed: 1996-05-22
Granted: 2009-01-20
Abstract: A "laser tape measure" for measuring distance which includes a transmitter such as a laser diode (43) which transmits a sequence of electromagnetic pulses in response to a transmit timing signal. A receiver samples reflections from objects within the field of the sequence of visible electromagnetic pulses with controlled timing, in response to a receive timing signal (42). The receiver generates a sample signal in response to the samples which indicates distance to the object causing th e reflections. The timing circuit supplies the transmit timing signal to the transmitter and supplies the receive timing signal to the receiver. The receive timing signal causes the receiver to sample (50) the reflection such that the time between transmission of pulses in the sequence in sampling by the receiver sweeps over a range of delays.

Title: Method for settling of suspensions with use of seepage force and vibrations
Inventor: TER-STEPANIAN GEORGE
IPC: B01D21/00
Filed: 1998-04-06
Granted: 1999-12-07
Abstract: Impossibility to settle mining tailings in form of hard sediments and forced storage of jelly-like sludge in tailings ponds have a great economic and environmental impact. This feature is caused by undiscovered until present suspension force that decreases the static unit weight of solid particles. Lesser dynamic unit weight is fanned, and solid particles settle extremely slowly. On sufficient concentration of suspension the solid particles become weightless and further settling is ceased. The solid particles remain in equilibrium for indefinite long time.  This force can be destroyed by greater seepage force and dense sediment can be obtained. A  number of auxiliary methods can be used, as vibration for destroying loose structure formed by rigid angular grains, diluting of thick suspensions. for initiating seepage, and applying supplementary hydrostatic pressure into closed container for increasing the hydraulic gradient. The method can be used for purification of impure liquids by settling the impurities.

Title: Method and apparatus for in situ field stator bar insulation capacitance mapping
Inventor: GARWATOSKI FRANK JOSEPH
IPC: G01R31/06
Filed: 1998-04-23
Granted: 2007-02-13
Abstract: A capacitance mapping tool consisting of an improved capacitance probe head assembly having an inflatable electrode bladder mounted at the end of a telescoping support pole is provided for enabling a service technician to accurately position the probe head assembly between stator bars of a large electric motor or power generator from a remote location.      Using the tool, capacitance measurements of insulation on stator bars can be obtained without removing the field. The tool is constructed such that it can be inserted between the field generating component (e.g., the rotor) and the stator windings of a large motor or power generator, thus, precluding the need for field removal. A bendable articulated tip section, which remains in a particular bend arrangement until manually reconfigured, is provided at one end of the tool where the capacitance measuring probe head is attached. This allows the probe head to be preconfigured at a particular angle with respect to the support pole and the stator bars prior to inserting. The probe head includes a bladder support plate which acts as a spacer and is adapted to accept one or more additional spacer plates for changing the overall width of the probe head to adjust for different spacings between stator bars. The pole supports an electric cable from the probe electrode to a remote electric meter and an air hose to a remote fluid source for inflating/deflating the probe bladder. The pole may also support a mount for a miniature TV camera. A remote actuator for controlling the fluid source to inflate and deflate the probe bladder is provided and adapted to worn by a service technician when performing measurements. A portable kit is provided which consists of the capacitance mapping tool, various accessories such as a video camera mounting bracket, probe spacer plates of various widths, electric cable lengths, vacuum tubing lengths and a belt mounted pressure actuator switch box.

Title: Generation of sweepout motion profile in an individual section glassware forming system
Inventor: NAFZIGER GREGORY W
IPC: C03B9/453
Filed: 1998-05-12
Granted: 2003-12-16
Abstract: In an individual section (IS) glassware forming system that includes a plurality of operating mechanisms for performing cyclic motions, an electronic controller for controlling cyclic motion of at least one of the operating mechanisms includes an electronic memory for storing a plurality of motion profiles for the one operating mechanism, with each of the profiles comprising a set of motion data versus time data. Each of the profiles has a piecewise linear contour determined by a plurality of control points, with each of the control points having associated motion and time data values. The operator may selectively display one of the profiles as a table of time values for the control points, with the time values preferably being in units of IS machine degrees. The operator may change the time values associated with one or more of the control points, and the controller automatically recomputes the motion data versus time data for the entire profile as a function of a change in time data by the operator at at least one of the control points, while maintaining the piecewise linear contour of the overall profile. Operation of the operating mechanism is thereafter controlled as a function of the recomputed motion versus time profile data.

Abstract: To facilitate saving of image data and movement of an image. An original image is displayed on a screen of a display device. An area to be extracted (cut out) from the displayed original image is designated by a mouse. Image data of an area other than the designated area is changed to image data representing a specified color. Pixel image data and coordinate data representing pixels in the (designated) area excluding the area of the specified color are produced.  Pairs of the pixel image data and the coordinate data is stored. Alternatively, a set of pixel image data and a set of coordinate data are respectively compressed, and compressed pixel image data and the compressed coordinate data are stored. To perform proper color correction (conversion) even when a user image is inlaid in a template image to produce a composite image. A position, in which the user image is to be inlaid, on the template image is defined by mask information. The template image and the mask information are correlated with each other. The user image is inlaid in the position, on the template image, defined by the mask information, to produce a composite image. Data representing the produced composite image and the corresponding mask information are transmitted from a client computer to an image synthesizer. In the image synthesizer, the mask information is referred to, to separate the template image and the user image from the composite image. The template image and the user image, which have been separated from each other, are individually subjected to color correction in the image synthesizer. The template image and the user image, which have been respectively subjected to the color correction, are resynthesized.

Abstract: A stent having varying outward radial force along its length. In use, the stent can provide greater force in vessel regions requiring greater force and less force in regions requiring less. In particular, more force is provided in the narrowed, center of a stenosis, while not applying too much force to the adjoining healthy tissue area. Greater stent expansion is provided in wider vessel geometries and less stent expansion in narrower regions. Varying force is achieved varying the number of elements, the density of elements, and the thickness of the elements.
