Abstract: A carbon film having an area of insulating material surrounded by an area of conducing material, and an area of material between the area of insulating material and the area of conducting material having a graded dielectric constant which varies from high to low from the area of insulating material to the area of conducting material. An emission site on the carbon film will emit electrons as a function of time, and as a function of distance across an emission site area.

Abstract: Field emission characteristics of carbon films are improved by changing the conditions of the growth of the films, by adding nitrogen, or substitutes to the nitrogen for hydrogen, in the carbon film growth process. Resulting field emission cathodes exhibit better field emission characteristics because of the increased concentration of nitrogen within the film.

Abstract: A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.

Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing treatment of a substrate and then depositing the film. The treatment step creates nucleation and growth sites on the substrate for the film deposition process and promotes election emission of the deposited film. With this process, a patterned emission can be achieved without post-deposition processing of the film. A field emitter device can be manufactured with such a film.

Abstract: A field emission cathode is provided which includes a substrate and a conductive layer desposed adjacent the substrate. An electrically resistive pillar is disposed adjacent the conductive layer, the resistive pillar having a substantially flat surface spaced from and substantially parallel to the substrate. A layer of diamond is disposed adjacent the surface of the resistive pillar.

Abstract: A method and system for projecting an image. An image projection system may include a sensor configured to detect the presence of an observer within a proximity of a medium, e.g., screen, window. In response to the sensor detecting the presence of an observer within a proximity of the medium, one or more portions of the medium may be switched from a transparent state to a substantially translucent state. At a substantially concurrent time as switching the one or more portions of the medium to a substantially translucent state, an image may be projected onto such portion(s). Hence, an image may be displayed in response to detecting an observer within the proximity of the medium.

Abstract: Before submitting a sample, including a first material layered upon a substrate, to an ion milling process, whereby a second material is sputtered onto the surface of the first material and the sample is then submitted to an etching process, an irregularity is formed on the surface of the first material. The overall process results in the formation of cones, or micro-tip structures, which may then be layered with a layer of low work function material, such as amorphous diamond. The irregularity in the surface of the first material may be formed by polishing, sandblasting, photolithography, or mechanical means such as scratching.

Abstract: When a riser card is connected to a computer system motherboard, a storage device on the riser card will contain configuration data permitting the computer system to configure any peripheral device on the riser card. The configuration data will be treated by the BIOS in the computer system as a virtual add-on ROM thereby allowing it to execute and initialize any and all PCI configuration spaces associated with the riser card peripheral devices.

Abstract: An image projection system comprises an image projector, such as a film or television projector and a projection screen. The projection screen is fabricated of a substantially transparent material, such as glass or plastic. The screen of transparent material has one or more areas or portions formed therein which areas or portions may be made to be translucent upon the application of a stimulus. Once in a translucent condition, the projected image can be received and viewed on the translucent portion. A mirror can be positioned behind the projection screen so that a person can view the reflection of themselves in the mirror when the screen is transparent, and an image can be projected when the projection screen is made to be substantially translucent.

Abstract: The present invention provides a glass BGA (ball grid array) including a glass substrate having a plurality of conductive leads, such as thin film metal deposited thereon. A die or chip is mounted in a fixed relationship to the glass substrate, and is often mounted on the glass substrate. The die includes a plurality of I/O pads for providing electrical access to circuitry inside the die. Circuitry is included for connecting the plurality of I/O pads to the plurality of conductive leads on the glass substrate.

Abstract: A ceramic actuator array is utilized to move a field emitter material for each pixel or subpixel to a level where an electric field causes electrons to be emitted from the emitter material towards a phosphor layer in an anode for that particular pixel. When the actuator is in an off state, then the field emitter material is removed to a different level where electrons are not urged to escape from the field emitter material. Thus, a display can be created using such an actuator array with field emitter materials deposited on each actuator element where each actuator element is individually controlled.

Abstract: A triode structure code cathode assembly is produced by depositing a carbon emitter material onto a substrate to form a cathode structure. Then, an insulating layer is deposited onto one side of a mesh foil to form a mesh assembly. This mesh assembly is then mechanically attached to the cathode structure so that the insulating layer on the one side of the mesh assembly is contacting the cathode structure. This entire triode cathode assembly can then be used to produce a field emission display device by including an anode structure.

Abstract: A data processing system includes a processor having a first level cache and a prefetch engine. Coupled to the processor are a second level cache and a third level cache and a system memory. Prefetching of cache lines is performed into each of the first, second, and third level caches by the prefetch engine. Prefetch requests from the prefetch engine to the second and third level caches is performed over a private prefetch request bus, which is separate from the bus system that transfers data from the various cache levels to the processor. A software instruction is used to accelerate the prefetch process by overriding the normal functionality of the hardware prefetch engine. The instruction also limits the amount of data to be prefetched.

The emission sites each contain at least two sub-regions having differing electron affinities. Use of the cathode to form a computer screen is also described along with the use of the cathode to form a fluorescent light source.

Abstract: A target detects the location of an impact of an object against a material by using various sensors. One utilization of the target is for a baseball or softball target whereby strikes and balls are detected depending upon the location of the impact of the ball against the target. The determination of the strikes and the balls is then provided to the thrower of the ball using some type of output device.
