The need for an automated target recognition system that can identify a target from a noisy image, irrespective of the target's orientation or size is identified. A novel pulse-coupled neural network is proposed to meet this need. The first step is to capture the image. Next, a neural network is used to determine whether an object of interest exists in the image. Next, another neural network deter ...

The DOT has identified the need for an emergency location service as part of the IVHS program. GPS has been proposed as a method of providing location in support of this "Mayday" service. However, the expense, slow time-to-first-fix, and inability to compute a navigation fix except when four satellites are visible make conventional GPS receivers inappropriate for emergency location. NAVSYS has dev ...

PRESENT SILICON IC'S ARE REACHING FUNDAMENTAL LIMITS ON GAIN, SPEED, AND POWER DENSITY. HETEROJUNCTION DEVICES PROMISE TEN-FOLD PERFORMANCE IMPROVEMENTS BUT LARGE-SCALE IC'S ARE REQUIRED TO ASSESS THESE EMERGING TECHNOLOGIES. SIGE HETEROSTRUCTURES OFFER SUBSTANTIAL PERFORMANCE INCREASES WHILE COEXISTING WITH CURRENT PROCESSING AND PACKAGING TECHNOLOGY. SILICON SUBSTRATES ARE EASIER TO MANUFACTURE ...

Q-Dot, Inc. proposes an innovative "no-drop" regulator (NDR) for low-voltage micro-power sensor systems. Based upon charge-coupled devices (CCD's), it provides high efficiency with less noise and at a low cost. Designed for battery or solar-cell systems, it has zero-volt input-to-output differential for highly efficient "no-drop" regulation. A 3 V NDR requires only two 1.5 V batteries, decreasing ...

Today, most solid modeling systems work well to precisely define the physical dimensions and properties of object's, but do not support automated reasoning. The capability to reason about model characteristics such as topology, tolerances, and complexity is important for developing integrated design and advanced manufacturing applications. Existing systems are oriented toward representing the gr ...
