Title: Parallel rendering of smoothly shaded color triangles with anti-aliased edges for a three dimensional color display
Inventor: EVANGELISTI CARLO J
IPC: G06T15/50
Filed: 1988-09-16
Granted: 1992-10-20
Abstract: PARALLEL RENDERING OF SMOOTHLY SHADED COLOR   TRIANGLES WITH ANTI-ALIASED EDGES FOR A    THREE DIMENSIONAL COLOR DISPLAY     Abstract of the Disclosure The present invention comprises a method for utiliz-ing an SIMD computer architecture in conjunction with a host processor and coordinate processor to render quality, three-dimensional, anti-aliased shaded color images into the frame buffer of a video display system.  The method includes a parallel algorithm for rendering an important graphic primi-tive for accomplishing the production of a smoothly shaded color three-dimensional triangle with anti-aliased edges.  By taking advantage of the SIMD architecture and said parallel algorithm, the very time consuming pixel by pixel computations are broken down for parallel execution.  A single coordinate processor computes and transmits an overall triangle record which is essentially the same for all blocks of pixels within a given bound-ing box which box in turn surrounds each triangle. The individual pixel data is produced by a group of M x N pixel processors and stored in the frame buffer in a series of repetitive steps wherein each step corresponds to the processing of an M x N block of pixels within the bounding box of the triangle. Thus, each pixel processor performs the same opera-tion, modifying its computations in accordance with triangle data received from the coordinate processor and positional data unique to its own sequential connectivity to the frame buffer, thus allowing parallel access to the frame buffer.

Title: Composting method apparatus utilizing air assist to aid in movement of organic matter
Inventor: SCHIENE THOMAS M
IPC: C05F17/02
Filed: 1989-09-28
Granted: 1994-11-22
Abstract: A composting  method  and  apparatus  is  disclosed  for accelerated decomposition of organic matter.  The organic matter is deposited into a chamber of a vessel.  A ram moves through a relatively short stroke within one end of the vessel so that organic matter deposited in the vessel at one end may be moved through the chamber and discharged at the other end as a result of  each  successive  charge  of material  pushing  the  preceding charge forward through the vessel by the action of the ram.  The vessel includes a set of orifices in a floor of the chamber for introducing pressurized air into the vessel.   During the normal composting operation, pressurized air passes through these ori-fices at a relatively low intensity to aerate the organic matter.          At certain times during operation of the ram, a surge of pres-surized air will be introduced into the chamber of the vessel through the orifices at such an intensity as to effect movement of the organic matter through the chamber with a ram force which is substantially less than the ram force required to move the organic matter absent the surge of air.  This provides a substan-tially  less  dense mass  of  organic matter moving through the chamber of the vessel than would be produced without the delivery of the surge of pressurized air.

Granted: 1999-08-24
Abstract: A liquid dispensing nozzle assembly is provided for mounting on a liquid container and dispenser having a flexible wall and liquid storage cavity for manually squeezed dispensing of a liquid from the cavity through the nozzle assembly. The nozzle assembly maintains the liquid, such as contact lens saline solution, in sterile condition during storage and repeated dispensing of the liquid from the container cavity. The nozzle assembly includes a liquid conduit for communication from the container cavity to a liquid discharge port from the nozzle assembly to enable dispensing of the liquid displaced by manually squeezing the flexible wall of the container. The nozzle assembly also includes an air aspiration conduit separate from the liquid conduit for aspirating air into the container cavity to replace the dispensed liquid. The nozzle assembly includes a partitioned diaphragm including separate portions respectively included in the liquid conduit and tree air aspiration conduit. The air conduit portion of the diaphragm can include a filter which is hydrophobic and air permeable but impermeable to bacteria to prevent entrainment of bacteria with the aspirating flow of air into the liquid storage cavity of the container.
