THE OBJECTIVE IS TO DESIGN AND FABRICATE A PROOF-OF-CONCEPT MODEL OF A NOVEL SIX DEGREES-OF-FREEDOM TRACKING DEVICE FOR MEASURING THE POSITION AND ORIENTATION OF A HEAD OR HAND IN AN AUGMENTED REALITY ENVIRONMENT. THE FEASIBILITY MODEL TO BE BUILT IN PHASE I WILL DEMONSTRATE GREATLY REDUCED SENSITIVITY TO NEARBY METAL OBJECTS, LESS SENSITIVITY TO ENVIRONMENTAL NOISE, A HIGHER MEASUREMENT RATE, LES ...

SENSITIVITIES IN MAGNETIC AND LOW-FREQUENCY ELECTROMAGNETIC BANDS HAVE BEEN LIMITED BY AMBIENT NOISE. SENSORS ARE AVAILABLE WITH EXTREMELY LOW NOISE LEVELS (ABOUT FIVE ORDERS OF MAGNITUDELOWER THAN THE AMBIENT NOISE). WE PROPOSE TO USE SUCH SENSORS IN AN ARRAY CONFIGURATION WHERE IT IS POSSIBLE TO OBTAIN SENSITIVITIES APPROACHING THOSE OF THE SENSORS THEMSELVES. ALGORITHMS FOR SUCH NOISE CANCELLAT ...

A BREAKTHROUGH IN ENGINEERING OPTIMIZATION METHODOLOGY HAS BEEN ACHIEVED, BASED ON TECHNOLOGY DEVELOPED IN THE DARPA INITIATIVE IN CONCURRENT ENGINEERING (DICE) PROGRAM. THE METHODOLOGY IS BASED ON A COMPLETELY RIGOROUS INTEGRATION OF UNCERTAINTY AND RANDOMNESS IN ENGINEERING OPTIMIZATION PROBLEMS. THIS INTEGRATION OF UNCERTAINTY AND RANDOMNESS SOLVES THE CRITICAL TECHNICAL PROBLEM OF CONCURRENT E ...

THIS PROPOSAL ADDRESSES THE DESIGN OF A LOW FREQUENCY AIRBORNE EARTH PENETRATING RADAR WHICH WILL DETECT BURIED OBJECTS AND EARTH CAVITIES (AS CONTRASTED TO IMAGING THEM). IT USES LOW DIRECTIVITY LOOP-DIPOLE ANTENNAS, GROUND CLUTTER CANCELLATION THROUGH FREQUENCY DIVERSITY AND POSSIBLY LOBE SWITCHING. IT MIGHT ALSO DETECT RADAR CAMOUFLAGE. WE ALSO PROPOSE .01 SCALE MODEL EXPERIMENTS TO SEARCH FOR ...
