Title: Digital video effects system; avoiding aliasing at object edges by supersampling.
Inventor: HEDLEY DAVID JOHN
IPC: H04N5/262
Filed: 1991-04-09
Abstract: A digital video effects system for generating an output image composed of output image pixels representative of a source image mapped onto a 3-D object surface, the digital video effects system including a memory for temporarily storing source image pixels, an address generator for generating memory read addresses in accordance with a surface function defining the 3-D object surface for mapping the source image pixels onto the 3-D object surface and a includes pixel interpolator for interpolating between source image pixels to determine an object image pixel where a object image pixel does not map directly onto that source image pixel, also includes an edge detector for detecting object image pixels corresponding to an edge of the object and an edge processor for supersampling each object pixel corresponding to an edge of the object to determine a respective edge image pixel, the edge pixels then being superimposed on the object image. The supersampling is peformed by testing for the intersection of a plurality of rays within a pixel and averaging the intensity values determined by each of the plurality of ray traces to determine a value for that edge pixel in the output image. <IMAGE>

Title: Removing air from packages
Inventor: HUTCHINSON GARRY DUANE
IPC: B65B1/26
Filed: 1992-06-05
Abstract: Apparatus (1) for removing excess air from sealed packages so as to prevent ballooning comprises a first conveyor belt (3) along which the packages (2) move through the apparatus (1). The conveyor (3) is driven by two rollers (4 and 5) and is also arranged to vibrate, by means of vibrator (2), in order to settle the contents, e.g. rice, in the packages throughout the operation. When a package is in a predetermined position, as determined by a sensor, such as a photoelectric cell, the package is punctured by a suitable device such as a spike (8). As the package continues down the conveyor (3), excess air is removed from the package by means of a spring loaded conveyor (19) which is biased against the package so as to force air out through the hole made by spike (8). Once the excess air in the package is removed, the package reaches a position where a sticker is placed over the hole in the package by a sticker applicator (14), which can be of any known type. <IMAGE>

Title: High pressure sealing system and method
Inventor: DRIESSEN JAN NICOLAS HENRI
IPC: F16F9/36
Filed: 1992-11-25
Abstract: A sealing system (12) for a hydraulic actuator (10) operable to selectively change the frictional sealing force exerted on a piston rod (22) in response to fluid pressure acting on the sealing system. A first seal member (72) operable for permitting a predetermined amount of fluid to leak from working chamber (16) to leakage chamber (76). A flow control valve (84) controls the flow of fluid from the leakage chamber (76) to a reservoir (86). A pressure responsive seal assembly (90) is operable to inhibit leakage of fluid from the leakage chamber (76) to the exterior of the hydraulic actuator (10) and is energizable in response to an increased fluid pressure within the leakage chamber (76) for generating increased frictional engagement with the piston rod (22) for preventing the vehicle body to sink during an extended stationary period of time. Furthermore, the pressure responsive sealing assembly (90) generates a reduced frictional engagement with the piston rod (22) when fluid pressure in the leakage chamber (76) is relatively low. <IMAGE>
