摘要:
There is disclosed apparatus for, and a method of identifying radar signals from selected of their parameters, such as azimuth, instantaneous frequency, pulse duration and the like, so that countermeasures may be initiated. Since the signals are sensed from several radars and occur at short intervals of the order of one microsecond or less, and, for effective countermeasures, the radar systems must be identified in a very short time, instantaneous evaluation of the parameters is demanded. The signals are evaluated by a matrix including a pattern of adaptive memory elements, such as magnetic or solid state memory elements (minstors) disposed in columns and rows. A parameter is assigned to the adaptive elements in each column so that each row of adaptive elements corresponds to a set of parameters. The elements in each row are encoded with a different set of adaptations corresponding to the parameters which it is anticipated will match the parameters of the radar systems. Adaptations derived from sensed parameters of a radar system, each corresponding to the parameters assigned to each column, are simultaneously impressed respectively on each column in comparing relationship with the encoded adaptation of the elements. The comparison takes place in real time (instantaneously) for all parameters. A measure of the total deviation of the impressed adaptation from the encoded adaptation for the elements of the row is derived for each row and a determination is made as to the identity of a radar system from the row manifesting the minimum deviation.

A shadow mask deposition system includes a plurality of identical shadow masks arranged in a number of stacks to form a like number of compound shadow masks, each of which is disposed in a deposition vacuum vessel along with a material deposition source. Materials from the material deposition sources are deposited on the substrate via openings in corresponding compound shadow masks, each opening being formed by the whole or partial alignment of apertures in the shadow masks forming the compound shadow mask, to form an array of electronic elements on the substrate.

A large area integrated solid-state flat panel display is detailed in which thin film transistor addressing and drive circuitry is provided at each individual picture point with a display medium. The preferred display medium is an electroluminescent phosphor layer. An insulating layer of laminated photoresist is disposed over all electrical circuit elements except the electroluminescent drive electrodes.

A system and method for active array temperature sensing and cooling. The system includes an active temperature sensing layer, a thermoelectric cooling layer and a heatsink layer. The temperature sensing layer is formed of temperature sensing elements that sense the temperature gradient across an unevenly heated region of the active array substrate. The thermoelectric cooling layer controls the temperature gradient sensed by the temperature sensing layer. The heatsink layer includes a plurality of cooling channels for absorbing thermal energy from the unevenly heated region. The system is under the control of a process control computer.

A method of producing a color filter to be used in conjunction with a display element such as an active or passive matrix liquid crystal panel. The color filter is formed by a stack of exposed and developed film layers, and each layer corresponds to a color of the resulting filter. The stack of exposed film layers is deposited on a transparent sheet.

An improved method of fabricating integrated circuits, particularly active matrix arrays. The present method comprises applying an etch-resist pattern to an integrated circuit by printing to form resist patterns. The circuit is then etched, recoated with a different substance, a new ink pattern applied and the pattern repeated to form the successive layers of the integrated circuit.

Evaporated receptacles for inkjet deposited polymeric light-emitting diode (PLED)/organic light-emitting diode (OLED) and a method of making the same. The evaporated receptacles are formed via a shadow mask vacuum deposition process. The method of forming a light-emitting display includes forming an electrode on a substrate, forming a receptacle structure over the electrode via a shadow mask vacuum deposition process, and delivering a quantity of polymeric solution, which contains a light-emitting material, into the receptacle via a standard inkjet deposition process.
摘要:
Electronic devices are formed on a substrate that is advanced stepwise through a plurality of deposition vessels. Each deposition vessel includes a source of deposition material and has at least two shadow masks associated therewith. Each of the two masks is alternately positioned within the corresponding deposition vessel for patterning the deposition material onto the substrate through apertures in the mask positioned therein, and positioned in an adjacent cleaning vessel for mask cleaning. The patterning onto the substrate and the cleaning of at least one of the masks are performed concurrently.
