Active Control eXperts, Inc. (ACX) proposes to apply its expertise in actuator and control system design to high force, high bandwidth machine tool position control applications. ACX proposes to develop novel hybrid linear actuators which can operate at high loads (greater than 1000 lbs.) at high bandwidths (in excess of 200 Hz), and at high displacements (0.018 inches). This innovative solid-stat ...

Uses of the central visual field, or foveal scotoma, due to accidental exposure to laser light or macular disease can cause serious impairments in visually aided performance. Foveal scotomas also interfere with normal control of eye reations and saccades. Feasibility is tested for using electronic image shifting from scotomatous foveal retina to intact peripheral retina, as a con\mpensation for ce ...

INNOVATIVE TECHNIQUES ARE PROPOSED FOR INVESTIGATION IN A PHASE I EFFORT TO DETERMINE PASSIVE RF SURVEILLANCE AND TARGETING SENSORS AND ASSOCIATED METHODOLOGY FOR PERFORMING RAPID AND ACCURATE MEASUREMENTS OF RANGE/LOCATION OF OTH THREAT RF EMITTERS. THE ESSENTIAL PHYSICAL CONSTRAINTS TO BE OBSERVED ARE SENSOR COMPATIBILITYWITH, AND PORTABILITY OF THE ASSOCIATED RANGE DETERMINATION/ PROCESSING EQU ...

A modified engine cycle based on the early intake valve closing of the Miller or the Adkinson cycle is proposed to meet the needs of the future Military Advanced Diesel Engine. The concpet involves the principle of short, effective compression with long expansion ratio to provide high brake thermal efficiency. This concept is executed by a variable timing rotary valve placed before the standard in ...

A RESEARCH PROGRAM TO PROVIDE SIMULATION MODELS APPLICABLE TO THE DESIGN SPECIFICATION OF A MICROWAVE MOISTURE SOUNDER OPERATING AT 183 GHZ IS DESCRIBED. THE DESIGN SPECIFICATION PROCESS CONSISTS OF INSTRUMENT RESPONSE SIMULATION, SENSITIVITY ANALYSES, AND MOISTURE RETRIEVAL PERFORMANCE ASSESSMENT. THE OBJECTIVE OF THE INITIAL EFFORT IS TO DEVELOP COMPUTER ALGORITHMS CAPABLE OF TREATING THE RESPON ...

THIS PROPOSAL IS TO DEMONSTRATE THE FEASIBILITY OF SWITCHABLE HOLOGRAMS IN RAPID (\ NANOSECOND) REPROGRAMMING OF VLSI CHIPS. THE CONCEPT WAS CHOSEN FOR HIGH SPEED, LOW SIZE, LOW COST, LOW POWER CONSUMPTION, AND MINIMUM WIRING. IT WILL RESULT IN HIGH FLEXIBILITY AND VERY RAPID REPROGRAMMING BUT WILL NOT BE AS FLEXIBLE AS A CROSS BAR SYSTEM. THE FINAL SYSTEM SHOULD SERVE REAL NEEDS, E.G. CHIP COMPUT ...

A TOTALLY NEW APPROACH TO HIGH QUALITY FLICKER-FREE IR MOVIE PROJECTION INVOLVING GRATING ENCODED REFLECTIVE IMAGES ON FILM IS DESCRIBED. THIS APPROACH IS DEMONSTRATED AND CAPABLE OF MEETING EACH OF THE REQUIREMENTS OF TOPIC NO. 29 AS WELL AS GIVING NATURAL (NOT "MONOCHROME") SPECTRAL SHAPES, EXTREMELY LARGE DYNAMIC RANGE, INDEPENDENT CONTROL OF DIFFERENT SCENE AREAS, AND READY EXTENSION TO CONCUR ...

SKIN COATINGS FOR IR SIGNATURE SUPPRESSION REQUIRE MORE THAN SIMPLE EMISSIVITY CONTROL. CONTROL OF THE DIRECTIONAL DISTRIBUTION OF EMITTED/REFLECTED RADIATION AND ACTIVE HEATING OR COOLING ARE ALSO NECESSARY. THE RADIANCE FROM THE OBJECT NEEDS TO APPROXIMATE THE RADIANCE FROM THE BACKGROUND OVER A BROAD RANGE OF VIEWING ANGLES. THIS REQUIRES A COMPLICATED BIDIRECTIONAL REFLECTANCE DISTRIBUTION FUN ...

AN APPROACH IS BEING INVESTIGATED FOR THE FLUORINATION OF DIAMOND THIN FILMS FOR TRIBOLOGICAL APPLICATIONS. THE APPROACH USES LOW PRESSURES OF F AND/OR CFX FREE RADICALS. TO DEMONSTRATE THE FEASIBILITY OF THIS APPROACH, DATA IS BEING COLLECTED ON: FLUORINATION KINETICS, THE COMPOSITION AND STRUCTURE OF THE SURFACE AND NEAR SURFACE LAYERS, THE EFFECTS OF TEMPERATURE ON THE FLUORINATION PROCESS, AND ...

The process of designing and evaluating advanced aircraft coatings can be made more efficient, more robust, and less expensive through application of highly accurate and flexible computer models. The General Scattered Light (GSL) model is such a signature analysis tool, but its potential is difficult to access by untrained or infrequent users, seriously limiting its value. We propose to overcome t ...
