Abstract: A method and apparatus for implementing a dynamic display memory is provided. A memory control hub suitable for interposition between a central processor and a memory includes a graphics memory control component. The graphics memory control component determines whether operands accessed by the central processor are graphics operands. If so, the graphics memory control component transforms the virtual address supplied by the central processor to a system address suitable for use in locating the graphics operand in the memory. In one embodiment, the graphics control component maintains a graphics translation table in the memory and utilizes the graphics translation table in transforming virtual addresses to system addresses. Furthermore, in one embodiment, the graphics control component reorders the addresses of the graphics operands to optimize for performance memory accesses by a graphics device.

Abstract: A system and method for controlling peripheral devices wherein at least one command is written to a location in a system memory and a write pointer is advanced. A peripheral device then reads the at least one command from that location in memory, increments a read pointer and executes the at least one command.

Abstract: A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may be applied at an add-on greater than 25%, and the web may travel at a speed of at least 60 meters per minute.

Abstract: An assembly to effect adjustments to the end play, or preloading, of a bearing set. The adjusting assembly utilizes a threaded bearing cup body and a correspondingly threaded adjusting ring. The bearing cup body abuts the outer race of the bearing and the adjusting ring is threaded onto the bearing cup body and abuts a fixed or stationary housing surface. The adjusting ring is rotated to adjust bearing preload and provide proper spacing. The bearing cap is then placed to lock the bearing adjusting assembly in place.

Abstract: A bathtub for the elderly or physically infirm includes several important innovations, namely a narrow front wall at one end of the bathtub permitting easy access to the bathtub, a wide front platform at the other end of the bathtub, and a plurality of sockets in the top wall of the bathtub for mounting accessories on the bathtub. The accessories include a railing extending around the ends and rear of the bathtub, with a headrest at one end of the railing, an inverted U-tube for mounting proximate the center of the bathtub for use when entering or exiting the bathtub, a seat assembly which can be fixed in one position extending transversely of the bathtub or rotated outwardly to a non-use position, and a backrest for releasable mounting on the seat assembly, so that the seat assembly and the backrest can form a compact unit for storage under the platform.

Abstract: A walking aid for physically challenged persons having front and back leg assemblies each having a front leg extending forwardly and a rear leg extending rearwardly and wheels at the lower ends of the legs, and modular hinges at the upper ends of each pair of legs. Each modular hinge has a bearing housing with bearing recesses, two bearing bodies, each bearing body being received in a respective recess. Each bearing body is interengagable with a respective front or rear leg, and, a transverse assembly bar is connected to the hinge mounting and secures the hinges in spaced apart side by side relation. Also disclosed is a brake locking system for an in-line two part brake handle, and a multi-use seat for a walker.

Abstract: A knee support for supporting an injured knee while permitting bending and straightening movements of such knee such movements involving both displacement of the femur portion of such joint away from the tibia portion and also involving sliding and tilting movement of such femur portion relative to such tibia portion, the knee support having an upper cuff which can be secured around a portion of a leg, above the knee, a lower cuff which can be secured around the leg below the knee, attachments on the upper and lower cuffs, and, linear bearings secured to the attachments on either side of the knee, the linear bearings enabling movement of one of the cuffs away from the other and enabling free displacement movement and sliding movement of the knee joint.
