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 ...

Frequency stabilized lasers are essential subsystems in many applications. Most importantly, they are used as flywheel oscillators in optical atomic clocks, as well as in many sensing and measurement systems, and some examples are down oil well sensing, l

ClearMark Systems has developed a sensitive and non-destructive inspection technology for identifying the point of origin of semiconductor chips.We capture the identifying information by analyzing markings on the silicon die or the chip package made by laser marking tools at the fabrication facility.Our Phase I effort has successfully distinguished markings that were made by a target tool versus s ...

Creative MicroSystems (CMC), of Waitsfield, VT, using external and internal funding sources, has been engaged in the design and development of a novel, multi-lens optical low-light imaging system (MOLLI)a revolutionary advance in night vision technology. Based upon a combined biomimetic/computed vision processing approacha significant departure from current night vision technologyCMC is developing ...

The proposed work will lead to the development of a flexible plasma simulation capability that can make use of computational accelerators such as GPUs when present. The eventual computational application will be able to transition from full fluid modelin

Due to the difficulties currently involved in fitting prosthetic sockets and the overall subjective nature of the process, DARPA seeks the development of innovative diagnostic tools for quantifying the characteristics of the socket-limb interface during the fitting process. In recent years, prosthetic design has made leaps and bounds implementing robotics to enhance prosthetic performance and ampu ...

In todays military, active special operators must be highly mobile and carry all their essential equipment and supplies with them. A major limitation to mobility is the need to carry fresh water. An individual must carry 12 to 24 pounds of water for each day they will be in the field without re-supply. It would be far better to be able to purify locally available water, but no technology exists ...
