Abstract: A system and method for applying non-homogeneous properties to multiple video processing units (VPUs) in a multiple VPU system are described. Respective VPUs in the system cooperate to produce a frame to be displayed. In various embodiments, data output by different VPUs in the system is combined, or merged, or composited to produce a frame to be displayed. In load balancing modes, each VPU in the system performs different tasks as part of rendering a same frame, and therefore typically executes different commands. In various embodiments, efficiency of the system is enhanced by forming a single command buffer for execution by all of the VPUs in the system even though each VPU may have a different set of commands to execute in the command buffer.

Abstract: A support 10 for a flexible trash bag 16 comprises a housing 12 having an open end 11, substantially planar first side 18 and second and third sides 20, 24. A pair of brackets 50, 94 on circumferentially opposing sides of the housing each have a cavity 51, 96 therein. A leg assembly for supporting the housing with the open end of the housing facing generally upward and the bag supported on the housing including at least one leg 52 selectively positionable within the receiving cavity in each of the pair of brackets 50, 94.

Abstract: A system and method for frame synchronization in multiple video processing unit (VPU) systems is described. In various embodiments, multiple VPUs cooperatively process frame data for display. According to embodiments, more than one VPU may not reside on a same card such that conventional synchronization methods are available. Frame data synchronization is accomplished in various embodiments by using semaphore mechanisms and by writing values to shared memory locations. For synchronization of execution among multiple VPUs operating on a same command buffer, execution of commands by one or more VPUs is stalled based on a semaphore value or a value in a shared memory location.

Abstract: A dual function lock, a tilt latch assembly, and tilt latch for use on a hung or double hung window are provided. The lock includes a base, a handle, and a tilt latch actuating mechanism. The tilt latch assembly includes a lock, left and right latches, and an extensible member. The tilt latch actuating mechanism is adapted to receive the extensible member and has a null zone between locked and unlocked positions of the handle. In the null zone, no substantial movement of the extensible member as the handle is rotated from the locked to unlocked positions. The tilt latch actuating mechanism causes the extensible member to move in a direction toward the lock as the handle is rotated from the unlocked position to a tilt position.

Abstract: A fenestration unit including screen coil apparatus is provided by the invention. The fenestration unit includes a frame defining an opening. A sash—is slideably received by the opening of the frame. The fenestration unit includes a screen coil assembly attached to the sash. The screen coil assembly includes a screen having first and second edges, and a roll core, wherein the screen is capable of being coiled and uncoiled on the roll core. The fenestration unit further includes an edge support having first and second support members having at least a portion located between the frame and the sash, the first and second support members for fastening to the screen first and second edges.

Abstract: The present invention comprises a printer system for a device that comprises a secure compartment and a top surface displaced at an acute angle relative to a floor. A portion of the secure compartment includes interior of an opening from the top surface. The printer system comprises a support frame attachable to the device and displaced in the secure compartment of the device. The support frame comprises at least one glide rail. The printer system further comprises a printer assembly attached to the support frame. The printer assembly comprises a media holder adapted to hold printable media, a chassis intermediate and attached to the media holder, and a printer attached to the chassis and adapted to print on the media. In a first position, the printer assembly is displaced substantially inside the secure compartment. In a second position, the printer assembly is extended away from the secure compartment.

Abstract: An insect screen frame assembly including a frame comprising a screen retention groove and a cover. The cover is configured to engage the frame and comprises a rib positioned to be inserted into the groove. Screening is held in tension between the frame and the cover and trapped between the rib and the groove. A first adhesive is positioned between the frame and the cover in contact with the screening.

Abstract: A mechanical heart valve assembly includes an orifice coupled with a stiffening ring and sewing cuff by a lock wire. The lock wire is made from a super-elastic material, e.g., a nickel-titanium alloy, and pre-formed into a C-shape. The lock wire is inserted between the orifice and stiffening ring by piercing the sewing cuff that surrounds the ring, and passing the lock wire into a window in the stiffening ring and into the aligned lock wire grooves on the stiffening ring and orifice. Once seated in the lock wire grooves, the lock wire retains its C-shape, providing a secure coupling between the orifice and stiffening ring.

Abstract: A foot operated mouse for controlling a computer, providing similar functions as a conventional hand operated mouse. The novel foot operated mouse has a base which rests on a horizontal pad or surface, and a separate platform for supporting the foot. A ball for generating positional signals based upon an x-and-y coordinate grid is fixed to the base. The foot platform is attached to the ball and can wobble, or simultaneously rotate and incline, thereon. Switch operators corresponding to conventional finger operated control buttons of a conventional hand operated mouse are provided. Preferably, these switch operators are hinged to the foot platform, and incline when depressed. In an alternative embodiment, the foot platform and switch operators are integral. In the latter embodiment, switch operation results from contact of the platform with the base. Preferably, the upper surface of the platform is inclined, thereby establishing a toe position and a heel position.
