摘要:
An image processing apparatus coupling at least two image processing systems connected to a network. The network couples image information to each system, and each system displays at least one image. Each system includes a communication unit and a control unit. The communication unit couples information to and receives information from the network. The control unit includes a central processing unit (CPU) and a partitioned memory space, including, both common and personal memory. The personal memory of each system contains one or more personal images that can be viewed only by the respective system, wherein each system is controlled to access only its respective personal memory. Under control of the CPUs in the respective systems, a common image is coupled to each system over the network and commonly displayed on each system. While the common image is commonly displayed on each system, it is edited by the first image processing system.

Method and apparatus for the selective scaling, such as magnification and reduction, of video images stored as collections of image pels in a video memory. A lookup table is provided for determination of the values of the scaled image pels. A framing matrix of unscaled image pels is established for each scaled image pel. The framing matrix for the scaled image pels determines the outputs read out of the lookup table, and derivatively, determines the values of the scaled image pels. The scaled image pels are stored in the video memory for subsequent display or processing.

An anti-flicker and anti-glow switchable load apparatus to be installed in the light socket of a commonly powered electronic switching device, such as a motion activated light switch. An energy efficient light bulb or lamp, such as a cathode fluorescent lamp or light emitting diode is then screwed into the apparatus. A first embodiment of the present invention includes a switchable light source, a switchable load, a controller, and a voltage sensor. When the present invention in the first embodiment detects a higher voltage, thus indicating the lamp has been switched from the “off” state to the on state, the switchable load is disconnected, and the current is re-routed to pass through the energy efficient lamp.

A method for enriching air with hydrogen for subsequent use by internal combustion engines is discussed. The method begins with supplying a modified form of water. Subsequently, the method continues with electrolyzing the water to produce hydrogen gas. Next, the method involves mixing the gas with air to produce a hydrogen-air mixture, and injecting the mixture into the air intake of a combustion engine. Also discussed is a system for enriching internal combustion engine air intake with hydrogen gas. The system uses modified water, an electrolysis unit for producing hydrogen gas from the modified water. The system mixes the gas with ambient air to create a mixture, and a venturi-based injector introduces the mixture into the air intake system of the engine.

A workstation with multiple, functionally related displays clustered under and controlled by a common transparent overlay control device. The position of a hand-held stylus is sensed by the overlay control device and is used as a system input to control system operations, system communications and input, manipulation and editing of images displayed on the displays. Control of certain workstation operations is achieved by directing the stylus towards function symbols which are affixed to the overlay surface. Actuators or other adjustment mechanisms are provided for adjustment of the height and pitch of the workstation for the comfort of the operator. Further, the workstation provides integrated data audio communication over ordinary narrow-band telephone lines or high speed data lines with other linked workstations.

A method and apparatus for compressing digital image data using interlocking digitate geometric sub-areas. The digital picture elements, or PELs, representing the image are divided into interlocking digitate sub-areas, which, in the preferred embodiment, are of substantially the same size and shape. Data compression is achieved for the PELs within a sub-area by first sorting the values of the PELs within the sub-area by magnitude. Depending upon the magnitudes of the PELs in the sub-area relative to the magnitudes of the other PELs in the sub-area, the PELs in the sub-area are either coded solid tone, with each PEL in the sub-area having the same tone, or coded bi-tonal, with each PEL in the sub-area having either one of two tones. A smoothing process is utilized to reduce undesireable effects at the edges of the sub-area.

The present invention provides means and methods for generating high resolution color computer generated graphic elements, such as lines, circles and curves, using a modified color-under coding system. A portion of the original luminance grey scale is reassigned or reallocated for substitution with data for high resolution graphic elements. High resolution graphic data are introduced by a user-operated input device via a control device such as a computer. The input luminance signal is digitally limited and stored in video random access memory (VRAM). A level detector detects the Y signal level to determine the presence of certain Y signal levels. Memory look-up tables provide appropriate user-determined substitute values for the Y, I and Q data values where certain, preselected Y signal levels are detected.

An optical position location apparatus for locating the position of an object in one or more dimensions, which relies upon one or more sources of radiant energy and distributor devices to disburse such radiant energy over a location region or window. Integrated collector assemblies positioned opposite to the distributors receive and collect the transmission of the distributed radiant energy and through reflection or refraction, transfer radiant energy to a minimum of detection locations to monitor the absence or alteration thereof. A rotating optical scanner and a detector are utilized with a continuous stationary light source to successively monitor specific location-coordinate-related portions of transmitted radiant energy and through electronic circuitry, a signal is developed to disclose, with accuracy, the location of objects within the location region "window", as well as other parameters including object size. In other embodiments, an apparatus with elements cooperating along two dimensions is capable of yielding three-dimensional object parameter information.
