Patent CA-2254470-C (CA)
Inventor: MUNROE EARL ROBERT
IPC: G06T15/50
Filed: 1998-11-24
Granted: 2004-01-20
Abstract: A method and apparatus for reproducing real-world lighting effects in a computer animated object, in which a three dimensional virtual set is created in proportion to the physical set, optical parameters of each physical light source used on the real-world set are input into the model and qualified by effects such as dimming, filtration, diffusion, occlusion and attenuation to produce synthetic lighting of the virtual set.  The camera lens transmission characteristics and film speed may also be incorporated into the virtual set parameters. The three dimensional computer animated object is positioned and oriented within the virtual set according to the position and orientation in which the visual effect is to appear in the cinematographic scene, and is thus synthetically illuminated within the virtual set in exactly the manner that a physical object of the same shape in the physical set would be illuminated, to produce a computer animated object that exhibits lighting effects as would appear in a comparable physical object photographed through the same camera lens using the same film as used in the physical set. The invention thus eliminates most of the judgment required on the part of a visual effects artist trying to reproduce in a computer animated object the lighting effects used in a cinematographic scene, and thus significantly reduces the time required to integrate the visual effect object into the cinematographic scene. Inherent characteristics of many light sources, filters, cameras and films can be maintained in a database or look-up table and can thus be entered into the virtual set by reference to the actual light sources and camera used on the real-world set.

Title: Lock system with key trapping
Inventor: EDEN CHARLES W JR
IPC: E05B11/06
Filed: 1997-07-18
Granted: 2006-01-03
Abstract: A cylinder lock (10) comprises a shell (14), a core (12), and a plurality of pin tumbler stacks (22, 24). The core includes an outer surface, a keyway and a cut-out offset from, but alignable with, at least on e of the tumbler stacks. A plate (34) disposed on the cut-out is movable between a first position, wherein the plate acts as an extension of the core surface to prevent a tumbler stack from entering the cut-out, and a second position, wherein the plate does not prevent a tumbler stack from entering the cut-out. Upon insertion of an authorized key (46) having a projection (58) extending from a side thereof, the projection urges the plate from the second position to the first position to permit the core to rotate to an unlocked position. Upon the insertion of a properly bitted key, but without the projection, only partial rotation is permitted whereupon the tumbler stack enters the cut-out to thereby render the lock inoperable and trap the unauthorized key within the keyway.

Title: Wavelength division multiplexed signal amplifier
Inventor: PEDERSEN BO
IPC: H04B10/572
Filed: 1997-10-09
Granted: 2011-06-21
Abstract: An optical signal processing method and apparatus for providing a noise feedback loop that uses exiting noise within the optical system to saturate a chain of amplifiers after the branching unit, thereby preventing information channels in a WDM signal containing empty channels from becoming overamplified as they pass through downstream amplifiers. The method and apparatus uses an existing drop amplifier which emits ASE noise as a side effect. A coupler connects the ASE noise to a filter. The filter ASE noise is fed into an existing trunk amplifier by a second coupler. The trunk amplifier increases gain to the filtered ASE noise to a level high enough to saturate the amplifier chain, without requiring an external noise generating device.

Abstract: A real-time method for routing subject to an acceptable delay constraint between nodes in high-speed data networks, such as PNNI protocol networks, uses an illustrative two-phase algorithm employing Dijkstra's algorithm at each phase. In an illustrative first phase, the Dijkstra SPF algorithm is used in seeking the shortest cumulative delay from the destination to the source, thereby generating cumulative delay labels from a node j to the destination node k. The delay results are then employed in the second phase, where the Dijkstra SPF algorithm is illustratively employed for determining administrative weight (AW) as the link metric subject to modification in accordance with results obtained in the first phase.

Granted: 2005-11-08
Abstract: A capless fuel filler neck has an annular resilient seal which seals over a fuel nozzle upon insertion in the filler tube. Further insertion of the nozzle opens a flapper biased against a rim flange on the lower end of annular seal. Movement of the flapper by the nozzle also moves an auxiliary seal on the flapper and which opens separate venting passages disposed externally of the nozzle tube. Upon removal of the nozzle from the filler tube, the flapper closes against the rim flange to seal the filler tube; and, the auxiliary seals close and seal the vent tubes. The vent tubes serve to prevent spray-back of fuel when the nozzle opens the flapper in a tank with pressurized vapor and fuel trapped in the filler tube and to provide an air inlet path to accommodate the aspiration of the refueling nozzle.
