Patent CA-2252786-A1 (CA)
Title: Video camera system
Inventor: JENKINS MICHAEL D
IPC: G06F1/16
Filed: 1998-11-04
Abstract: This invention involves the use of a body worn mobile computer with a video camera to allow image alignment. Quite frequently a video camera user cannot look directly into the camera because of some obstruction. In these cases, in order to be sure the camera is pointed in the right direction and toward the object to be captured by the image, a head mounted display worn by the user and connected to a computer can simplify this process. An example of where this system can be used is when the camera operator is located in the rear of a crowd watching a parade. He or she can hold the camera viewer above the crowd and view the image in their head mounted display thereby moving the camera viewer in the desired direction. The visible image can then be simultaneously displayed to the wearer (or user) and stored or recorded on the wearable computer or even transmitted via the computer peripherals to a remote location.

Patent CA-2267591-A1 (CA)
Title: A system for editing complex visual data providing a continuously updated renderings
Inventor: KRATTLI JEAN-MARC
IPC: G06T15/00
Filed: 1999-03-30
Abstract: An authoring system provides a realistic rendering that may be updated and displayed continuously while simultaneously allowing full access to all authoring tools. The system is an enhancement to an authoring environment for 3D modeling. The rendering is incorporated in the authoring environment in a way that avoids conflicting with the abstract images and tools useful for working with models such as would obtain in a WYSIWYG implementation. The computational burden of rendering is handled by rendering in an asynchronous parallel thread with respect to that supporting the authoring UI. The number of pixels that must be ray-traced is reduced by several mechanisms including: limiting the number of objects, limiting the resolution of the display, tailoring the size of the field-of view window (while providing orientation context by placing the rendering on top of a wire-frame view). Also, only portions of the scene that are affected in a visible way by updates are re-rendered. The rendering fits into the authoring context by forming it in a selectable-size region in a wire-frame or other type of view.  Also, the authoring UI thread is executed at a higher priority than the rendering thread (or some other control means) to insure the UI is not slowed down. The rendering is placed on top of a wire frame so that it fits into and takes advantage of the wire-frame view without interfering with it substantially. The rendering window can be tailored to show precisely the part of the scene the author is working on.

Title: Air density system with air recirculation and gyrating bar feeder
Inventor: BIELAGUS JOSEPH B
IPC: B07B11/04
Filed: 1997-09-25
Abstract: An air density separator (20) has a vertical air separation chamber (24) that opens downwardly to allow rejected material (54) to fall out from the chamber (24) through the open bottom. The air density separator (20) is configured to recirculate the air and entrained fines, and so minimizes emissions and costly air treatment processes. The air separation chamber (20) is connected by a first duct (26) to a cyclone (28). A fan (30) is positioned adjacent the lower end (34) to the air separation chamber (24), and draws air through a second duct (27) out of the cyclone (28) for reintroduction into the air chamber (24). The fan (30) by way of the cyclone (28) draws air through the first duct (26) from the air separation chamber (24). The fan (30) exhausts into the vertical air separation chamber (24) below the material infeed (61) through a plenum (31). An oscillating screen (36) composed of bars (38) extends into the separation chamber (24) of the air density separator (20) and is used to disperse material into the separation chamber (24). The bars (38) are spaced apart to allow air to be drawn up through the bars (38) to separate the light component (56) in the feed material (44) from heavier materials (54). A tray (61) to which the bars (38) are mounted is caused to oscillate by an eccentric weight (50) which is mounted to the bars (38) and driven to oscillate in a horizontal plane. The tray (61) is suspended by four universal linkages (47) to a support frame (46), the linkages (47) allowing the tray (61) and attached bars (38) to oscillate.

Title: Jawed crimping tool and method of use
Inventor: MORALES STEPHEN A
IPC: A61F2/06
Filed: 1999-04-28
Abstract: A stent crimping tool for firmly and uniformly crimping a conventional or radioactive stmt onto a balloon catheter is constructed from a housing having a proximal section rotatably connected to a distal section. A cylindrical cavity having a tapered end is formed into the proximal section.  Inside the cavity is affixed a transparent cylindrical collar having radial slots leading to a central passage extending along its axis, and a conical end that fits into the tapered end. Teeth made of trapezoidally-shaped flat plates each having an angular proximal edge and a radiused edge slide into their respective slots in the collar. A transparent screw-feed having a hollow core and a slotted head that receives the radiused edge of each tooth and plate is threaded to the distal section. A  balloon catheter is passed through a passage in the proximal section and the collar and an uncrimped stmt positioned in the hollow core of the screw is loaded thereon. Rotating the distal section of the housing advances the screw and teeth towards the tapered cavity, which has angled walls that force the teeth to converge radially inward. This convergence causes the radiused edges of the teeth to collectively crimp the stem onto the balloon catheter.
