Patent CA-2207909-A1 (CA)
Title: Amplitude to phase conversion logic using interference
Inventor: HAIT JOHN N
IPC: G06K9/74
Filed: 1995-12-14
Abstract: An apparatus and method is disclosed for providing at least one phasemodulated output from at least one amplitude-modulated input, which is used to produce logical AND and OR functions having phase-modulated outputs. A constant level bias beam set (5) of at least one wavelength of any wave-type energy is superimposed on at least one modulated input beam set (3, 4) having an energy sum out of phase with the bias beam set at at least one location (7). Energy in the resulting interference image (8) is separated from said at least one location to produce at least one output (9). Input levels determine the function performed. When the input energy sum is greater than the bias beam set, the output changes phase. When they are equal, the output is zero, which is also used to produce the NAND function.

Title: Improved loss of potential determination for use in protective relays for electric power systems
Inventor: HOU DAQING
IPC: H02H3/38
Filed: 1997-07-18
Abstract: The positive sequence voltage on the power line is measured at a given time, i.e. the present time, and also for one cycle earlier, and the ratio thereof is then compared against a threshold value of 0.9.   There are four other supervisory tests which also must be true for a loss of potential  condition  to  be  indicated.     These  include determination of change in positive sequence current and angle and zero sequence current and angle.  If the change in those values is smaller  than selected thresholds, then a loss of potential condition is indicated.

Inventor: MCEACHERN RODERICK JOSEPH
IPC: G21F9/06
Filed: 1996-05-14
Abstract: The present invention relates to a process for removing rare earth elements (RE) from spent nuclear fuel.

IPC: H04N5/225
Filed: 1996-07-26
Abstract: A video surveillance system (10) has a camera equipped with a fisheye lens (20) having a substantially hemispheric field of view. The system (10) implements operations equivalent to pan, tilt, and zoom of a conventional camera. The camera produces a distorted fisheye image due to the properties of the fisheye lens (20). The system (10) corrects the distortion by mapping the pixels of the fisheye image to coordinates produced by selecting a particular part of the fisheye image to be viewed. The fisheye image formed by the camera is split into four separate image components (15, 16, 17, 18) carried by four bundles of optical fibers (35, 36, 37, 38). Each bundle has a CCD (45, 46, 47, 48) and associated image processing circuitry (65, 66, 67, 68) which forms an electronic representation of the image component carried by that bundle.
