Patent CA-2211626-A1 (CA)
Inventor: SCARPETTI JULIUS J
IPC: G06K15/00
Filed: 1996-01-30
Abstract: Apparatus and methods are disclosed for the production of digitized stereoscopic polarizing images. The transfer of dichroic inks into stretched and oriented substrates to form stereoscopic polarizing images and the like can be improved by the use of coatings that enhance imbibition of the ink into the substrate. The coatings serve to hold the ink in situ for a sufficient period of time to permit absorption of the dye and transfer of rich colors while minimizing the problems of smearing and/or runoff of unabsorbed ink. The present invention is particularly useful in the adaptation of ink jet printing techniques to the formation of stereoscopic polarizing images.

Title: Monitoring of nonlinear effects
Inventor: ROBERTS KIM BYRON
IPC: H04B10/08
Filed: 1997-11-26
Abstract: An optical transmission system comprises a number of optical terminals connected by optical waveguides such as optical fibres. Nonlinear processes occurring within an optical transmission medium of the waveguide or within the optical terminals is detected by a monitor which outputs monitored data representative of the products of nonlinearity. The data is used to control the power of the optical signal such that power is regulated to avoid the onset of the nonlinear process. The data may also be used to indicate an alarm condition to an operator. A monitor for four wave mixing detection utilises dither signals applied to respective frequency components of a wavelength division multiplexed signal, products of the four wave mixing process being detected in the monitor by correlation between a sample of a received optical signal and reference data representative of dither induced modulation in the four wave mixing product. Mutually orthogonal dither wave forms are derived from pseudo-random sequences and applied as low frequency modulations to transmitted optical signals. Such monitors allow optical power to be controlled and assist in locating defective equipment requiring remedial action. The invention has application to long haul optical transmission systems.

Title: Methods, apparatus, and articles of manufacture for use in forming stator slot wedges
Inventor: HAZELTON THOMAS JAMES
IPC: H02K15/10
Filed: 1998-01-20
Abstract: A slitting and scoring machine includes an upper tooling roller and a lower tooling roller that cooperate to define a tooling nip. Each tooling roller includes an alternating series of coaxially arranged annular knives, annular dies, and annular mandrels. A web of insulation is drawn through the tooling nip to simultaneously (i) cut the web into strips, (ii) score the strips in a manner that promotes the forming of the strips, and (iii) partially form the strips into modified U-shapes. Each strip includes a longitudinally extending middle segment and a pair of longitudinally extending side segments that extend away from the middle segment in a divergent manner to define a longitudinally extending channel. Longitudinally extending grooves are formed by the scoring at the junctures of the middle segment and the side segments. The scoring / grooves promote the divergent shape of the strip. In an end profile view of the strip, the middle segment and each of the side segments are generally straight, and an obtuse angle is defined between each side segment and the middle segment. Each strip is formed into a roll, so that a first length of the strip and a second length of the strip each extend around a common point. At least a portion of the second length is disposed within the channel of the first length.
Patent CA-2229027-A1 (CA)
Title: Method and system for rendering graphical objects to image chunks and combining image layers into a display image
Inventor: VERES JAMES E
IPC: G06T15/00
Filed: 1996-08-02
Abstract: To render a display image, the system serially renders chunks of the gsprites, and composites the gsprites to compute a display image. To reduce rendering overhead, the system can perform affine transformations on gsprites to simulate the motion of a 3D object rather that re-rendering the object for frames animation. Rendering geometry in chunks enables sophisticated fragment list anti-aliasing. The system stores fragments representing partially covered pixel locations or translucent pixels in a fragment buffer. After rasterizing primitives for a chunk, a fragment resolution subsystem resolves the fragments to compute output pixels. The rasterizing component of the system attempts to merge fragments to save fragment memory. If the fragment memory is exceeded, the system can subdivide chunks into smaller regions and render these smaller regions independently. The system supports texture accessed in environments with high latency such as in cases where texture data is compressed. The latency of texture accessing is reduced using either a texture reference or "pixel queue" to buffer partially rendered pixel data as texture data is fetched from memory, or using a pre-rasterizer to generate texture requests and a post-rasterizer to rasterize primitives completely using texture data fetched as a result of the texture requests generated by the pre-rasterizer.  The system support anisotropic filtering of texture data by repetitively sampling texture data along a line of anisotropy computed for pixel location mapped into a texture or MIP mapped textures.

Patent CA-2232739-A1 (CA)
Inventor: THOMAS ANTHONY
IPC: G08G1/07
Filed: 1998-05-22
Abstract: SATDS is a device that becomes a fixture to any combination of traffic lights.   From a fixed position, close to the light cluster (with the three speed sensors pointing towards traffic flow) this device (automatically activating when lights turn from green to yellow) will start to monitor approaching traffic.   If a vehicle is approaching too fast, each of three sensors (set at different distances from the traffic lights) will digitally accumulate a ten-second time delay.  The amount of time delay is relevant to speed limit and is adjustable. The ten-second time delay would be passed to the central traffic light control bank. (if vehicle manages to stop within yellow light duration, time delay will be cancelled) and be added to the normal three-second duration of the cross flow traffic 'Red Light' (also the pedestrian lights) allowing the runaway vehicle to run the red light without incident.   Traffic lights will then return to normal, the device will go to standby ready for next yellow light.

Filed: 1998-06-19
Abstract: A method of manufacturing a thick steel product of high strength and high toughness having excellent weldability with minimal variation of material properties, comprises heating a steel raw material to the temperature of Ac3 to 1350°C, hot rolling and then cooling at the cooling rate of 10 °C/sec. or less. The steel raw material has the following composition:      C: 0.001 - 0.025 wt%;      Mn: 1.0 - 3.0 wt%;      Ti: 0.005 - -0.20 wt%;      Nb: 0.005 - 0.20 wt%;      B : 0.0003 - 0.0050 wt%; and Al: 0.01 - 0.100 wt% balance substantially Fe and incidental impurities.      The composition has a transformation start temperature (Bs) of 670°C or less. Since the steel product obtained by the method has no variation in physical properties regardless of variation in cooling rate, it is possible to supply steel products of high strength and high toughness which have uniform microstructure and properties along their thickness direction and are excellent in weldability.
