ALPHATECH PROPOSES TO DEVELOP INNOVATIVE ALGORITHMS FOR AIRBORNE MULTI-SPECTRAL COUNTERMEASURE MANAGEMENT BUILT UPON OUR PREVIOUSLY DEVELOPED ADVANCED ALGORITHMS FOR ELECTRONIC COUNTERMEASURE (ECM) POWER MANAGEMENT FOR USE AGAINST GROUND-BASE AIR DEFENSE THREATS. THESE ALGORITHMS DETERMINE OPTIMAL COUNTERMEASURE SEQUENCES BY PREDICTING IN REAL-TIME HOW THREATS WILL RESPOND TO COUNTERMEASURES. IN S ...

THE PERFORMANCE OF MANY ADVANCED UNDERWATER ACOUSTIC SENSOR SYSTEMS IS LIMITED BY UNWANTED NOISE CAUSED BY THE TURBULENT BOUNDARY LAYER (TBL). THE TBL MAY ALSO EXCITE UNWANTED NOISE AND VIBRATION (FLOW NOISE) IN A VARIETY OF MARINE AND AIRCRAFT VEHICLES. A SIGNIFICANT AMOUNT OF FLOW NOISE REDUCTION HAS BEEN REPORTED WHEN ANISOTROPIC COMPLIANT WALLS HAVE BEEN TESTED. THE PROPOSED WORK IS TO DEVELOP ...

AN INTEGRATED ACOUSTIC ARRAY AND SIGNAL PROCESSING SYSTEM WILL BE DEVELOPED FOR THE DETECTION, TRACKING AND IDENTIFICATION OF ROTARYWING AIRCRAFT. THE TECHNIQUE USES A RUGGED PIEZO-ELECTRIC POLYMER SENSOR AND A PROPRIETARY TELEMETRY SYSTEM. A COMMERCIALLY AVAILABLE ARRAY PROCESSOR IS USED TO PERFORM THE REQUIRED SIGNAL PROCESSING.

ATLANTIC APPLIED RESEARCH CORPORATION HAS BEEN DEVELOPING A VERY HIGH ACCURACY LASER SURFACE SHAPE MEASUREMENT SYSTEM. IT CURRENTLY HAS THE ABILITY TO SCAN A MEASUREMENT LASER BEAM IN ONE DIMENSION AND MEASURE THE POSITION OF THE SURFACE OF ALMOST ANY OBJECT IT STRIKES RELATIVE TO A REFERENCE PLANE. THIS NON CONTACT LINEAR DISPLACEMENT SENSOR PROJECT WOULD INVOLVE ADAPTING THE SCANNING MECHANISM S ...

THIS PROPOSAL PRESENTS A PLAN FOR DEVELOPING AN ANALYSIS FRAMEWORK AND AN AUTOMATED LIFE-CYCLE COST MODEL FOR THE EVALUATION OF ICBM GUIDANCE AND CONTROL (G&C) SYSTEM OPTIONS. THE PROPOSED FRAMEWORK INCORPORATES THE CONCEPT OF SYSTEM MISSION AVAILABILITY (MA) AND ALSO INCORPORATES MODELS FOR THE HARDWARE ARCHITECTURE, LOGISTICS SCENARIO AND MAINTENANCE POLICIES, AS WELL AS THE MORE TRADITIONAL REL ...

THE OBJECTIVE OF THIS PROJECT IS TO ADVANCE THE STATE-OF-THE-ART OF VISION GUIDED ROBOTIC WELDING (SEAM TRACKING) BY THE DEVELOPMENT OF EXPERT SYSTEMS CAPABLE OF ADAPTING THE WELDING PARAMETERS TO COMPENSATE FOR WELDING PROCESS DISTURBANCIES. IN PHASE I OF THE PROJECT, WE WILL FOCUS ON ADAPTATION TO JOINT GEOMETRY VARIATIONS AND ESTABLISH THE FEASIBILITY OF THE OVERALL APPROACH. EXPERIMENTS WILL B ...

A NOVEL APPROACH TO THE SAFETY OF RESERVE BATTERIES IS TAKEN, BASED ON A BATTERY DESIGN THAT ELIMINATES THE USE OF A SEPARATE RESERVOIR TO STORE THE ELECTROLYTE DURING INACTIVE LIFE OF THE BATTERY. CELLS WITHOUT THE ELECTROLYTE AND THE ELECTROLYTE ITSELF ARE SITUATED IN A BATTERY CONTAINER, STORED UNDER VACUUM. THE BATTERY IS ACTIVATED SIMPLY BY ADMITTING THE AIR INTO THE CONTAINER. THE AIR FORCES ...
