Abstract: A three-dimensional image display system includes an array of directionally-modulated pixels or light emitting picture elements. Each directionally-modulated pixel (DMP) emits light which is modulated in a manner that is not uniform in all directions, to insure that the light emitted in each included direction is appropriate for the scene being displayed. In this manner, observers viewing the scene from various positions see a scene generated by the image display device that closely simulates the three-dimensional attributes of the real objects located in the real scene being reproduced.

Abstract: Apparatus for use in conjunction with a vise to provide a secured work station in which the vise grips the vise engaging device connected to the work station with a first locking force in a first direction and a locking assembly is provided to secure the vise engaging device with a second locking force in a second direction different than the first direction.
Abstract: In a system for compressing video data, the degree of global motion between a plurality of successive frames is determined for use in designating and spacing reference frames, relative to the global motion exceeding predetermined thresholds or levels of motion between certain ones of the frames.
Abstract: In a method using organic vapor phase deposition (OCPD), for the growth of thin films of optically nonlinear organic salts, a volatile precursor of each component of the salt is carried as a vapor to a hot-wall reaction chamber by independently controlled streams of carrier gas. The components react to form a polycrystalline thin film on substrates of glass and gold. Excess reactants and reaction products are purged from the system by the carrier gas. For example, the method provides the growth of polycrystalline, optically nonlinear thin films of 4'-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) with >95% purity.

Abstract: A coin or token-operated amusement ride comprises a base having a drive unit therein and one or more driven arms extending therefrom and supporting a ride seat which is moved cyclically for a period of ride operation by the drive unit upon actuation by payment of one or more coins or other tokens into the ride, wherein there is further provided a camera unit mounted on the ride and directed toward the ride occupant/user and adapted to be triggered during operation of the ride to take a photograph of the ride occupant. A printer may deliver the finished print to the ride occupant as the ride operation ends.
Abstract: The frequency components of an input pulse are dispersed into divergent respective rays that are applied to an acousto-optic modulator after being collimated. The amplitude of each frequency component emerging from the modulator is determined by the amplitude and phase of a grating formed therein by modulated radio frequency wave applied to it. The parallel rays emerging from the modulator are focussed onto a device for forming an output pulse.

Abstract: A system for testing a condom includes a housing containing a porous liner having an interior cavity conformed to the exterior shape of a condom to be tested, whereby a holder carrying the condom is inserted into the liner, a closed pathway for gas flow is provided between a gas port of the holder and the interior volume of the condom, for permitting the condom to be inflated with the gas, causing the exterior walls of the condom to be pushed against opposing inside walls of the liner, permitting gas passing through holes in the condom to flow through pores in walls of the liner to another gas port of the housing for detecting unacceptable holes in the condom using differential pressure techniques and/or gas tagging.

Abstract: A three-way elbow for connection between a trap and a waste line is provided with a valved access ending in a plug. Removal of the plug allows attachment of a first end of a hose in its place. The second end of the hose is held above the water level of a sink by attachment to a board that fits over the sink. A snake inserted through the hose is directed by passageways in the elbow to the waste line. A container is mounted between a faucet for the sink and the second end of the hose so that disinfectant in the container can be carried into the hose. Brushes are mounted in the second end of the hose so as to aid in cleaning the snake as it is withdrawn.
Abstract: A wire tensioning device for use in repairing breaks in wires strung between supports comprising a pair of drums that revolve about parallel axes, belts of insulating material respectively wrapped about each drum, a motor coupled to drive said drums in either direction, and a decoupler for each drum.
Abstract: Apparatus and method for decaffeinating a liquid, especially brewed coffee in which caffeine is removed by imposing an electrostatic field in counteracting relationship to the flow of the coffee and drawing the caffeine to and retaining the caffeine on an ionic resin.

Abstract: Effluent to be treated is introduced into the top of a first bioreactor 10 through an inlet pipe 16 and, after passing through second and third bioreactors 11 and 12, passes through a settling device 17, the treated effluent then flowing over a depth control weir 18 into an outlet pipe 19. The three bioreactors 10, 11 and 12 and the settling device 17 are housed in a tank having three sets of vertically-staggered transverse partitions 21, 22, 23 and a transverse settling tank partition 24. Each set of staggered partitions 21, 22 and 23 are arranged so that the bioreactors are interconnected in series, the effluent preferably being constrained to pass downwardly through each matrix 13, 14, 15 in turn against an upward discharge of very fine air bubbles from aeration panels 28 which extend under substantially the whole of each matrix. Aerobic bacteria feeds on nutrients in the effluent and grows on the roughened walls of the cross-flow matrix and the air bubbles promote sloughing of the bacteria.
Abstract: Apparatus and method for forming a metal oxide film on a glass substrate in which ambient air and particularly water vapor is prevented from reaching the initial nucleation site by injection of dry gas at a point such that ambient air is excluded from the area around the upstream edge of the injector where the film first starts to be formed. Crystal growth inhibiting gas is injected so as to reach only the initial nucleation site to improve the nucleation process, thereby improving film properties without decreasing the overall film thickness. Application of the above methods in the deposition of tin oxide yields improved haze control of the tin oxide film, including very low haze coatings.

Abstract: A clip assembly for retaining a semiconductor wafer on a pedestal during processing of the wafer, and releasing the wafer for removal from the pedestal after processing, includes a pair of tines each having a lower sloping surface for contacting an edge of an associated semiconductor wafer, and a ledge provided immediately above the lower sloping surface inward from a shared leading edge serves to catch debris or particulate material, preventing it from falling onto the surface of the semiconductor wafer. A metal spring, biasing the clip head into contact with the wafer, has an upper portion affixed to a front face of the clip head via an electrically nonconductive rectangularly shaped retainer for substantially reducing voltage arcing between the highly electrically charged plasma used in processing a semiconductor wafer and the clip head.
Abstract: A file folder locating system which includes a transmitter to selectively transmit packets of radio frequency cycles indicative of the coded address of a particular folder. A transponder, attached to the folder, receives the transmission and responds thereto by producing an audible sound which enables the file to be easily located.
