  • Patent number: 5701444
    Abstract: A rendering subsystem with enhanced capability for handling both 2D rendering and 3D rendering tasks. Since the 2D rendering tasks may be generated by the operating system (or other user-interfacing software), it is highly desirable not to interfere with rapid performance of 2D rendering, even if substantial 3D rendering tasks have been loaded into the pipeline. To avoid this, the innovative system uses dual independent contexts, and suspends 3D rendering operation during periods of 2D rendering demand. Moreover, a certain percentage of cycles is reserved, as a minimum, to be available for 2D operations if any have been requested. Window ownership identifiers are maintained for each pixel, but these identifiers are only updated when the 3D rendering operations have been suspended. Moreover, the window position (offset) values are only updated during periods when 3D rendering has been suspended.

  • Patent number: 5425562
    Abstract: A game dragging device is provided which includes a first, handle member and a first game grabbing member. The handle member has a pair of leg members and a first hole proximate the distal end of one of its legs. It also has at least a second hole which is located substantially at the mid point of the leg. A first, hook member, is provided which has a barb-like member at one end and a hole proximate its other end. A first rotation member rotatably secures the handle member to the hook member to form a first unit. A second unit is provided which is essentially identical to the first unit. The first and second units are rotatably secured to each other such that the first unit being positioned so as to be reversed relative to second unit. The handle member and the first hook member are secured to each other to form a unit which is essentially in the form of an S-shaped member.
