Patent number: 6031529Abstract: The present invention relates to method and apparatus for presenting a graphical user interface for use in displaying graphics on a computer display. A frame window is launched that includes a main menu and defines a window border that bounds a user work surface on a display monitor. A first borderless child window is attached to the frame window. This first borderless window is a graphics display window for displaying an image on the user work surface. One or more additional borderless child windows are attached to the frame window. These other child windows display controls such as buttons and icons that allow the user to control depiction of the image within the first borderless child window. The buttons and icons have a sculpted appearance that appears raised in a first state and appear reversed when `depressed` or activated by the user.Type: GrantFiled: June 27, 1997Date of Patent: February 29, 2000Assignee: AVID Technology Inc.Inventors: Charles J.

Patent number: 6023703Abstract: A method and system for representing hierarchical time-based data structures and to extract information therefrom comprises means to create a container, the container having one or more layers within which data elements are arranged along the container axis and to examine the container to produce virtual static graphs which represent active data elements and their interconnections within time durations represented within the container. The data elements in the container can change between active and inactive states with time and the connections between data elements can also change with time and the container represents this information. A set of constraints is defined for the container such that interconnections between data elements only occur between data elements in different layers. Specifically, a data element can only receive input from one or more other data elements which are in lower levels and a data element can only provide output to one or more data elements which are in higher levels.Type: GrantFiled: May 24, 1999Date of Patent: February 8, 2000Assignee: Avid Technology, Inc.Inventor: Raymond Hill

Patent number: 6014150Abstract: A system and method for defining and employing behaviours for articulated chains in computer animations. At least one control, such as a shape control or a resolution plane control, is defined for the articulated chain and is employed as a constraint by the animation engine when animating the chain with inverse kinematics. Each control comprises two or more keys, each key comprising a couple of an effector direction vector and an associated constraint. In the case of shape control keys, the associated constraints comprise a list of preferred limb orientations and in the case of resolution plane control keys, the associated constraints comprise a preferred orientation for the resolution plane. For any given goal, selected control keys are interpolated with appropriate weightings to obtain a resulting constraint to be employed by the animation engine.Type: GrantFiled: October 7, 1997Date of Patent: January 11, 2000Assignee: Avid Technology, Inc.Inventor: Yves Boucher

Patent number: 5977982Abstract: "A system and method for modification of the visual characteristics of digital 3D objects includes a shading buffer wherein parameters relating to the visual characteristics of a rendered 3D object are stored. When a texture applied to the 3D object is selected for modification, a pre-rendering step is performed and a shading buffer constructed. The shading buffer includes pre-computed components of the visual characteristic information for each rendered pixel of the displayed 3D object, these components are independent of the texture selected for modification. When the texture is modified, by indicating one or more pixels on the 3D object to which the texture is applied, re-rendering of those pixels is accomplished by evaluating a simple combination of the corresponding pre-computed components in the shading buffer and the modification effected to the selected texture to obtain new final values to render the pixels.Type: GrantFiled: June 28, 1996Date of Patent: November 2, 1999Assignee: Avid Technology Inc.Inventor: Laurent Lauzon

Patent number: 5938666Abstract: A unitary clamp integrally structured from two U-shaped members respectively disposed one from the other by an interjoining web between proximate arms of each U-shaped member, distal ends of each member having latching means mechanism so as to latch, simultaneously, both U-shaped members into a closed position and the interjoining web sheets spacially disposing each U-shaped member into adjacent closing engagement about an umbilical cord. The web sheets are cut by a pair of scissors to sever the cord and one of the U-shaped clamp members is thus attached to the umbilical cord attached to the abdomen of an infant while the other to the umbilical cord connected to the placenta. On voiding of the placenta, the latter is discarded. When healing of the umbilical cord to the infant is achieved, that clamp member may be removed or discarded.Type: GrantFiled: March 27, 1998Date of Patent: August 17, 1999Assignee: University of Western OntarioInventors: J.
