THE PERFORMANCE OF IMAGING SYSTEMS IS HIGHLY DEPENDENT ON THE INTENSITY AND DISTRIBUTION OF LIGHT ILLUMINATING THE SCENE. THE HUMAN VISUAL SYSTEM PERFORMS WELL OVER A RANGE OF SCENE BRIGHTNESS FAR GREATER THAN THAT WHICH MAN-MADE IMAGE SENSING SYSTEMS ARE CAPABLE OF OPERATING. ODETICS, INC. PROPOSES AN OPTICAL MODEL WHICH: GREATLY INCREASES THERANGE AND VARIABILITY OF SCENE ILLUMINATION; VASTLY IM ...

THIS IS A PROJECT LEADING TO DEFINITION OF A DIGITAL-PROCESSOR SYSTEM FOR SMALL SPACECRAFT. THE FIRST PHASE OF THE PROGRAM WILL EXAMINE SEVERAL SMALL-SATELLITE PROGRAMS TO DETERMINE A TYPICAL, SMALL-SATELLITE MISSION. NEXT, THESE REQUIREMENTS WILL BE TRANSLATED INTO SPECIFIC REQUIREMENTS FOR AN ATTITUDE-CONTROL SYSTEM THAT WILL GUIDE HARDWARE AND SOFTWARE DECISIONS. HARDWARE QUESTIONS AS INTERFACE ...

IF A PRACTICAL DIRECT CALORIMETER SYSTEM WERE AVAILABLE FOR THE MEASUREMENT OF METABOLIC HEAT RELEASES IN ANIMALS IN ORBITAL LABORATORIES, IT WOULD BE POSSIBLE TO QUANTIFY SUCH PROCESSES AS 1) CHANGES IN BONE MINERAL AND MUSCLE STATUS (AS A RESULT OF WEIGHTLESSNESS) AND 2) CHANGES IN THE IMMUNESYSTEM (AS A RESULT OF STRESS AND RADIATION FORCE FIELDS) INTERMS OF THE CORRESPONDING METABOLIC CHANGES. ...

LOCAL MEMORY, PARALLEL PROCESSING COMPUTER SYSTEMS OFFER THE POTENTIAL TO REALIZE PREVIOUSLY UNAVAILABLE LEVELS OF PERFORMANCE AT COSTS FAR LOWER THAN CURRENT UNIPROCESSOR TECHNOLOGY PERMITS. HOWEVER, THE ARCHITECTURES OF THESE PARALLEL SYSTEMS PRESENT DIFFICULT PROBLEMS FOR BOTH DATA ACCESS AND DATA COMMUNICATIONS. THE ARACHNID SYSTEM IS PROPOSED AS A GENERAL SOLUTION TO THESE PROBLEMS. ARACHNID ...

Future lunar site operations will benefit from mobile robots, both autonomous and tele-operated, that complement or replace human extravehicular activity. Three-dimensional sensing technology is at the heart of such functionality, enabling reliable navigation in complex, dynamic environments, and serving as a valuable tool for inspection and site survey. Honeybee Robotics is therefore developing ...

DEVELOPMENT OF AN ADVANCED MONOLITHIC GAAS 8.5 VOLTAGE CONTROLLED OSCILLATOR WITH ON-CHIP GENERATION OF A LOW FREQUENCY REFERENCE OUTPUT, SUITABLE FOR PHASE LOCKED LOOP APPLICATIONS, IS PROPOSED. CIRCUIT ELEMENTS AND DESIGNS TECHNIQUES TRADITIONALLY RESERVED FOR MICROWAVE APPLICATIONSARE UTILIZED TO OBTAIN THE HIGH SPEED DIVIDE BY N CIRCUIT. A COHERENT REFERENCE SIGNAL IN THE 90-200 MHZ RANGE IS T ...

MANUFACTURING METHOD FOR HIGH ELEVATED-TEMPERATURE STRENGTH FIBERS INCORPORATING RECENT ADVANCES IN SINTERING TECHNOLOGYAND REFRACTORY METAL ALLOY DEVELOPMENT WILL BE INVESTIGATED.A CONTROLLED ATMOSPHERE SINTERING OF POWDER METALLURGY INGOTS OF NEW MOLYBDENUM AND TUNGSTEN ALLOYS UNDER A SELECTED CHEMICAL POTENTIAL ENVIRONMENT, IN CONJUCTION WITH SUBSEQUENT OPTIMIZED WIRE DRAWING PROCESS MAY PRODUC ...

Materials Innovation Technologies LLC is developing a method for making polymer matrix composites fiber preforms that has the potential to revolutionize the industry. The Three Dimensional Engineered Preform (3-DEP) process represents the state-of-the art in chopped fiber preform manufacture. 3-DEP produces a homogeneous fiber distribution within parts and consistent part weight and dimensions f ...

THE GOAL OF THIS PROJECT IS AN INNOVATIVE METHOD OF ENHANCING THE CONTROLLABILITY OF AIRCRAFT AT MODERATE-TO-HIGH ANGLES-OF-ATTACK (AOA) BY CONTROLLING THE FOREBODY VORTEX FLOW WITH ROTATABLE NOSE-BOOM STRAKES. THE IDEA IS TO CONTROL THE ASYMMETRY OF THE NOSE-BOOM WAKE BY PLACING SMALL, MOVABLE STRAKES ON THE NOSE-BOOM. THE WAKE THEN ACTS AS A CONTROLLED PERTURBATION ON THE FOREBODY FLOW AND SUBSE ...

Flutter is a potentially explosive phenomenon that results from the simultaneous interaction of aerodynamic, structural, and inertial forces. The nature of flutter mandates that flight testing be cautious and conservative. In addition to the flutter instability, adverse aeroelastic phenomena include limit cycle oscillations, buffeting, buzz, and undesirable gust response. The analytical prediction ...
