Patent number: 4597162Abstract: A method of making a parallel programmed electronic matrix array including the steps of forming at least one layer of a phase changeable material on a conductive substrate, wherein the phase changeable material has a substantially nonconductive state and a comparatively high conductive state. The layer is formed in one of the states. The method also includes irradiating selected areas of the layer to simultaneously convert the selected areas of the layer to the other one of the states to form selected substantially nonconductive layer portions and selected comparatively high conductive layer portions. Thereafter, in a preprogrammed embodiment, first and second sets of electrically conductive address lines are formed on respective opposite sides of the layer.Type: GrantFiled: October 7, 1985Date of Patent: July 1, 1986Assignee: Energy Conversion Devices, Inc.Inventors: Robert R.

Patent number: 4593199Abstract: A device and method for converting an X-ray image into a corresponding output image with light from a different source and a phosphorescent layer in conjunction with a liquid crystal light valve. The light valve includes a photosensor layer comprised of a deposited semiconductor material having distinct light and dark photoconductivities, the light photoconductivity being substantially greater than the dark photoconductivity.When impinged upon by an particular pattern of X-rays, the phosphorescent layer phosphoresces in a corresponding pattern, which phosphorescence in turn causes the semiconductor layer to be switched to its light photoconductivity in a pattern also corresponding to that of the input X-ray image. The pattern of switched semiconductor in the photosensor layer allows a biasing voltage to be switched over to the liquid crystal layer of the light valve in a corresponding pattern.Type: GrantFiled: January 22, 1985Date of Patent: June 3, 1986Assignee: Energy Conversion Devices, Inc.Inventors: Zvi Yaniv, Robert R.

Patent number: 4588903Abstract: A high speed digital electronic system includes a plurality of logic or switching circuits for providing one or more bits of discrete output in response to applied input signals. At least some of the circuits include devices switchable between at least two logic states, and are formed from materials of the type which exhibit increased switching speeds when maintained in a dynamic mode of operation. Signal source means apply to the system dynamic signals for maintaining the switchable devices in a dynamic mode of operation. The switchable devices are preferably formed from amorphous semiconductor alloys including silicon and may take the form of diodes to form AC logic AND gates, OR gates or a matrix selection circuit. The dynamic signals take the form of alternating major and minor clock pulses having a frequency between 10 and 40 megahertz. The logic circuits are arranged to form a binary adder.Type: GrantFiled: October 24, 1983Date of Patent: May 13, 1986Assignee: Energy Conversion Devices, Inc.Inventor: Robert R. Johnson

Patent number: 4547891Abstract: An apparatus for monitoring the operation of a press provides outputs indicating the total number of hits and the operating speed of the press as well as the total amount of product produced by the press.Specifically, an N-Pulser is driven by a proximity switch coupled to the press so as to fill an accumulator that maintains a running total of the amount of product produced. The N-Pulser includes a gate that has an enabling input coupled to the proximity switch and a signal input coupled to a clock. When the gate is enabled the output of the clock is permitted to pass through the gate to the input of a counter, the counter having been preset to a state determined by the amount of product produced during each cycle of the press. The gate is disabled when the counter has counted to a predetermined, ZERO, state. The output of the gate is in a parallel fashion coupled to the accumulator, so that a specified number of pulses are dumped into the accumulator as a result of each cycle of the press.Type: GrantFiled: December 8, 1983Date of Patent: October 15, 1985Assignee: GTE Products CorporationInventors: Frank J. Avellino, Robert R. Johnson
