Patent CA-2286784-A1 (CA)
Inventor: RAWLEY CURT A
IPC: G06T19/00
Filed: 1998-04-01
Abstract: In a media production system, two-dimensional images captured from physical objects are analyzed to create three-dimensional representations of the physical objects within a virtual stage. Representations of physical and synthetic objects are manipulated and choreagraphed in the virtual stage within an integrated system which also generates a media product in the form of a two-dimensional image stream of the physical and synthetic objects with optional synchronized audio tracks. A correlation is maintained between object models in the virtual stage and the original two-dimensional images so that information from those images can be included in the final product. To facilitate direction of combined media products, a composite display of the three-dimensional virtual stage and a two-dimensional preview are provided.  Also provided are a score display providing temporal representations of elements within the scene and an object catalog of object oriented representations of elements within the scene.

Patent CA-2317962-A1 (CA)
Inventor: DARA FOROOGH S
IPC: A45D26/00
Filed: 2000-09-01
Abstract: Effective hair removal is often achieved by plucking or removing hair from the root. Plucking hair is often either expensive or involves chemicals that are messy and impractical to use, and could result in allergic reactions or burns on sensitive skins. Hair removal methods that do not involve the above are usually inefficient. This invention is a simple pocket size manual device used for safely and easily removing unwanted facial and other non-coarse body hair. The device consists of a coil attached at each end to a handle. It is approximately the size of a small pencil, and may be used anywhere with no need for a mirror. To pluck hair, the device is bent while held at its handles, brought into contact with the skin, and twisted while it is moved in the opposite direction of hair growth. The invention works like tweezers in that it plucks unwanted hair without the use of chemicals or electricity. It is also as economical and environmentally friendly as tweezers. However, since it plucks dozens of strands of hair with one twist of the fingers, and since it requires minimal attention to apply, it is much more practical, efficient, and effective to use than tweezers are.

Patent CA-2330066-A1 (CA)
Inventor: CROME VICTOR P
IPC: B64D10/00
Filed: 2000-12-29
Abstract: An anti-G system is used to combat the push-pull effect experienced by airmen during and after a transition from a period of low or negative G force levels to high G force levels. The anti-G system includes an anti-G controller configured to receive signals indicative of airman acceleration and anti-G garment pressure. The anti-G controller is coupled to a valve controller controlling fill and vent valves controlling the pressure level in the anti-G garment. As the anti- G controller receives acceleration signals indicating G force levels over time, the controller calculates whether the anti-G garment pressure should be increased or decreased and transmits signals to the valve controller to increase or decrease anti-G garment pressure. Increasing the anti-G garment pressure compensates for the airman's loss of tolerance to high G levels immediately after exposure to a period of low or negative G levels.
