摘要： Analog to digital converter for two-dimensional radiant energy array computers in which the converter stage derives a bit array of digital radiant energy signals representative of the amplitudes of an input radiant energy analog signal array and derives an output radiant energy analog signal array to serve as an input to succeeding stages. The converter stage includes a digital radiant energy array device which contains radiant energy array positions so that the analog array is less than a predetermined threshold level and which doesn't contain radiant energy at array positions where the input analog array exceeds the threshold level. A scaling device amplifies the radiant energy signal levels of the input array and the digital array so that the radiant energy signal level carried by the digital array corresponds to the threshold level. An adder device adds the signals of the scaled input and digital arrays at corresponding array positions to form the output analog array.

摘要： Two-dimensional digital computers and computer devices operate in parallel on rectangular arrays of digital radiant energy optical signal elements which are arranged in ordered rows and columns. Logic gate devices receive two input arrays and provide an output array having digital states dependent only on the digital states of the signal elements of the two input arrays at corresponding row and column positions. The logic devices include an array of photoconductors responsive to at least one of the input arrays for either selectively accelerating electrons to a phosphor output surface, applying potentials to an electroluminescent output layer, exciting an array of discrete radiant energy sources, or exciting a liquid crystal to influence crystal transparency or reflectivity. An image combiner/duplicator serves as an interface device for either converting two spaced apart input arrays to a combined input array or for converting an input array to two spaced apart output arrays. Interconnecting devices provide an output array having signal element digital states dependent on the states of non-corresponding input signal elements. Such devices include: a slider for translating the output array with respect to the input array; a twister for rotating the output array by a multiple of 90.degree.; an interchanger of rows and columns; an inverter of row or column element order; a magnifier responsive to a subarray of an input array; a spiller device responsive to the state of a single input element; a contractor device having an output signal element responsive to a digital 1 of any input element; a sweeper device for producing redundant rows or columns corresponding to a single input row or column. Memory devices utilizing the gates in conjunction with regenerative feedback also serve to threshold analog images. An A/D converter system converts an analog input image into bit planes. An array computer system organization includes array mask gating for performing different operations simultaneously on different image portions.

摘要： Two light paths are disposed to induce resonant coupling of light energy from one path to the other. Electrodes connected to an electrical source are positioned relative to the two light paths and to develop electric fields which inhibit the resonant coupling from one light path to the other. A photoconductive region is positioned in one of the two light paths or in an additional third light path so that transmission of light energy through the photoconductive material produces a lowered resistance path between the electrodes, substantially diminishing the potential across the electrodes, and causing commensurate dimunition of the electric fields so that resonant coupling is inhibited between the resonantly coupled optical paths. Three light paths may be employed to provide an optical AND gate while two light paths can be arranged to provide an optical OR gate.

摘要： The state of a sensing device such as a switch is indicated as a logic signal at a circuit output terminal and a malfunction is indicated at another circuit output when the connections to the sensing device open circuit or short circuit. The input circuit employs a pair of LED photo-isolators which conduct during alternate half cycles of an a-c current which is applied through the sensing device when it is closed. A diode connects in shunt with the sensing device and when the device is open, only one of the photo-isolators conducts. If a malfunction occurs, neither photo-isolator conducts.

摘要： An optical device for gating an incident light ray which utilizes the principle of absorption edge shift in a semiconductor due to an external electric field. The optical device comprises a semiconductor material and a source of bias potential applied thereacross. In a preferred embodiment, a PN junction is provided for control purposes such that the potential is primarily dropped across the junction. The absorption band edge of the semiconductor is selected to correspond to the wavelength of the incident radiation to be controlled whereby in the normal mode of operation, the semiconductor appears to be transparent to the incident radiation. When charged carriers are introduced at the junction, the potential is dropped across the semiconductor, causing an absorption edge shift towards longer wavelengths. In this mode of operation, the incident radiation is substantially absorbed, or attenuated, by the semiconductor.
