STUDIES ARE DESIGNED TO DEVELOP CORNEAL MASKS, FORMED IN SITU, WITH KNOWN CENTRAL RADII OF CURVATURE. MASK FORMATION WILL UTILIZE A NEW TECHNOLOGY, ALLOWING APPLICATION OF A VISCOUS FLUID TO SMOOTHE OVER ALL CORNEAL IRREGULARITIES BEFORE GELLING IN PLACE. MASK FIRMNESS WILL BE ACHIEVED CHEMICALLY IN THE PRESENCE OF A HARD CONTACT LENS. LENS REMOVAL WILL LEAVE AN ABLATABLE MASK OF THE SAME CURVATUR ...

TO CONSTRUCT AN EMULATION CAPABILITY FOR EXISTING OR PLANNED ROBOTIC COMMAND CENTERS (RCCS) WE PROPOSE TO APPLY TECHNOLOGY DEVELOPED FOR SIMULATION AND CONTROL OF TELEOPERATED SERVICING ROBOTIC SYSTEMS TO THE PROBLEM. AS PART OF A COLLABORATION WITH IN THE CENTER FOR AUTONOMOUS AND MAN-CONTROLLED ROBOTIC AND SENSING SYSTEMS, A NASA SPONSORED CENTER FOR COMMERCIAL DEVELOPMENT OF SPACE AUTOMATION AN ...

THE GOAL OF THIS PROGRAM IS TO DEMONSTRATE A HIGH-RESOLUTIONACTIVE RANGING SYSTEM USING LOW-TEMPERATURE-GROWN (LTG) GAAS PHOTOCONDUCTORS AS DEPTH SENSORS. THESE NEWLY-DEVELOPED SOLID-STATE DEVICES ARE CHARACTERIZED BY AN EXCEPTIONALLY BROAD FREQUENCY RESPONSE (UP TO 375 GHZ @ -3 DB) AND A VERY HIGH SENSITIVITY (70% QUANTUM EFFICIENCY). TO REDUCE THE NOISE BACKGROUND THEY CAN BE GATED ON A PICOSECO ...

The advanced technology described in this proposal promises to increase the performance of laboratory and, specifically, tabletop x-ray lasers by up to an order of magnitude. Such gains in performance coupled with compact technology will lead to the introduction of the world s first table-top, commercial x-ray laser. Tetra proposes to develop an advanced driver for the laboratory laser based upo ...

M-Vision Inc., along with the University of Michigan and Michigan State University, proposes to develop a new and novel solution to the problem of target detection and discrimination in a complex scene. This solution is obtained by innovatively combining Gabor wavelets and scale space inference. The result is a computational model of human perception that resembles the human visual system in its ...

MANY COMBUSTION EXPERIMENTS INVOLVING PARTICLE SIZING AND RADIATION MEASUREMENT REQUIRE AN ACCURATE KNOWLEDGE OF THE REFRACTIVE (N) AND ABSORPTION (K) INDICES OF SOOT. EVEN THOUGH SOOT IS A COMPLEX HYDROCARBON WITH A PARTICULARLY HIGH C:H MASS RATIO, VALUES FOR N AND K FOR CARBON ARE OFTENUSED AS BEING EQUIVALENT FOR SOOT. LITERATURE VALUES OF N AND K FOR SOOT AND CARBON SHOW WIDE SCATTER: 1.40

THE DEVICE DESCRIBED IN THIS PHASE I PROPOSAL INCORPORATES A NOVEL TECHNIQUE FOR USING RF AS AN ENHANCEMENT TO FACILITY SECURITY SYSTEMS. RF HAS OFTEN BEEN INVESTIGATED AS A METHOD FOR PROVIDING A NON-LETHAL DETERRENT TO INTRUSION INTO SECURED FACILITIES SUCH AS STORAGE FACILITIES FOR NUCLEAR WEAPONS. THE PRIMARY PROBLEM ASSOCIATED WITH THE SYSTEMS THAT HAVE BEEN STUDIED HAS BEEN THE ABILITY TO CO ...

A quality simulation which allows a user to simulate the acoustic emissions in a multi-source environment and then study the effects these conditions have on a set of acoustic sensors would be of great value. As acoustic sensors technology continues to advance with robust algorithms for detection, tracking and identification as well as high performance hardware providing real-time operation, thes ...
