Abstract: The present invention provides improvements to an array processor for analyzing two dimensional arrays of spatially related data elements. More specifically, provision is made to permit a cellular array processor (10) to efficiently perform data dependent processing such as floating point arithmetic functions. In the preferred embodiment, one module (84) in the array processor (12) generates a signal applied to bus line (24) when all of the bits in a register (86) are zero. The signal on bus line (24) effects the shifting operation of a shift register (36) in a memory module (34) located on a different functional plane. Thus, the processing functions carried out in each elemental processor (26) can be made to depend on the value of data stored therein instead of being dictated solely by a simultaneous executed instruction from the control processor (14) as is the normal case.

Abstract: An infrared (IR) simulator is disclosed in which an array of pixels is defined on an insulative substrate by resistor bridges which contact the substrate at spaced locations and are separated from the substrate, and thereby thermally insulated therefrom, between the contact locations. Semiconductor drive circuits on the substrate enable desired current flows through the resistor bridges in response to input control signals, thereby establishing the appropriate IR radiation from each of the pixels. The drive circuits and also at least some of the electrical lead lines are preferably located under the resistor bridges. A thermal reflector below each bridge shields the drive circuit and reflects radiation to enhance the IR output. The drive circuits employ sample and hold circuits which produce a substantially flicker-free operation, whith the resistor bridges being impedance matched with their respective drive circuits. The resistor bridges may be formed by coating insulative base bridges with a resistive layer having the desired properties, and overcoating the resistive layers with a thermally emissive material. The array is preferably formed on a silicon-on-saphire (SOS) wafer. Arrays of electromagnetic radiation bridge detectors may also be formed, with the bridges having either resistor, thermocouple or Schottky junction constructions.

Abstract: An electron beam addressed crystal light valve (LCLV) produces an AC voltage across a liquid crystal layer from a single polarity electron beam, and exhibits very high resolution. A mirror (20) and a thin layer of partially conductive material (24) are deposited on a support membrane (22) on the electron beam side of the liquid crystal (8). The partially conductive layer (24) is divided into a series of pixel elements by a conductive matrix (26) which faces the electron beam. Electrons from the beam are absorbed by the partially conductive layer (24) to establish a negative voltage across the liquid crystal, and then flow out to the conductive matrix (26) to produce an AC voltage (30) prior to the next electron beam scan. The conductive matrix (26) is connected in circuit with a transparent electrode (18) which provides a voltage reference on the readout side of the liquid crystal. The elements of the device are designed with electrical parameters that produce a discharge rate from the partially conductive layer (24) fast enough to complete an AC cycle between successive electron beam scans, but slow enough for the liquid crystal to respond and produce an image.

Abstract: A process for fabricating a semiconductor device by thermal gradient zone melting, whereby metal-rich droplets (24) such as aluminum migrate through a semiconductor wafer (14) such as silicon to create conductive paths (22). One surface of the wafer (14) is placed intimately adjacent a heating surface (42) to establish a high and uniform thermal gradient through the wafer (14). Heat in the wafer (14) is removed from the other wafer surface. The apparatus for practicing the process comprises a base (40), heating means (44) and heat sink (46) means. Heating means (40) comprises a platform (40) having a generally planar heating surface (42) adapted to receive the entire area of the one surface of at least one wafer (14). The heat sink means (46) is spaced away from the other wafer surface to form a space (48) therebetween, the space being adapted to receive a high heat conductive gas. The heat sink means (46) and the gas cooperatively remove the heat in the wafer (14) to enhance the establishment of the thermal gradient. One surface of the wafer may be provided with a buffer layer (70) thereon, which is placed directly on a heating surface (42). The buffer layer (70) terminates the migration of the droplets to prevent allowing of the droplets with the heating surface (42).

Abstract: A single-Schottky liquid crystal is disclosed in which a series of Schottky contacts are made on one side of a photoconductor substrate by a metal matrix mirror, with a doped semiconductor back contact electrode on the other side of the substrate.

Abstract: An optical beam scanner incorporating an array of beam deflection elements commonly controlled to steer an optical beam impingent on the array is described. The beam steering elements are arranged in the array as individually controlled elements and the deflection of the beam is accomplished by setting the phase tilt and the phase offset of each element according to a calculation which removes modulo 2 pi phase shift from the required position relative to a flat plane. Thus, the array elements can be thin and need only supply about 2 radians of phase shift. These elements may be incorporated in a planar array using beam deflection elements such as liquid crystal beam deflectors by choosing a drive scheme representing either a blazed array or a flat piston array. Operation may be designed for a large range of light wavelengths and the system may efficiently accommodate a combination of the blazed and flat piston techniques to obtain beam deflection characteristics otherwise unavailable by the exclusive use of each individual technique. By use of the liquid crystal phased array approach, rapid, high accuracy, large area beam deflection is possible without the necessity of any moving parts and with low power drive requirements. Phased arrays of the type described above may be arranged in successive parallel planes with an common beam axis to provide two-dimensional beam deflection.

Abstract: An electron beam addressed liquid crystal light valve (LCLV) produces an AC voltage across a liquid crystal layer from a single polarity electron beam (6), and exhibits very high resolution. A thin layer (24) of partially conductive material is deposited on a support membrane (22) on the electron beam side of the liquid crystal (8). A conductive, electron beam permeable sheet (26) is formed on the back of the partially conductive layer. Electrons from the beam are absorbed by the partially conductive layer (24), and then flow back out to the conductive sheet (26) to produce an AC voltage prior to the next electron beam scan. The conductive sheet (26) is connected in circuit with a transparent electrode (18) which provides a voltage reference on the readout side of the liquid crystal. The device is designed with electrical parameters that produce a discharge rate from the partially conductive layer (24) fast enough to complete an AC cycle between successive electron beam scans, but slow enough for the liquid crystal (8) to respond and produce an image. A separate mirror (20) can be provided to reflect the readout beam (14a, 14b) back through the liquid crystal, or the conductive sheet (26) can itself serve as a mirror.
