Weidlinger Associates Inc. proposes to develop effective technology for simulating explosive detonations within civil buildings where the propagation of airblast and failure of weak internal walls are strongly coupled. We will conduct a field test program designed to complement other internal detonation testing efforts such as DTRA''s Distinct Cobra, expanding the available database. We will perfo ...

In Phase I of this effort we analyzed the structural response of a BLU 109 during typical penetration events. Based on these finite element results, we proposed and demsonstrated a simple robust concept for a passive penetrator sensor that identifies the material being penetrated and also correlates strongly with its underground trajectory. Such a sensor would obviously provide valuable informatio ...

Conversion of highly stable optical clocks into electrical clocks through photodetection introduces excess phase noise, thereby degrading the frequency stability. This noise is primarily generated due to the conversion of optical intensity noise into electrical phase noise by photodiode¿s non-linearity, specifically power-to-phase conversion. During Phase I, Discovery developed dual photodiodes h ...

This is an SBIR Phase II proposal to develop a tactile refreshable computer display prototype (TRCD) that will support multiple tactile alphabets (e.g. ELIA, braille, and Roman), multiple lines of text, and graphics to benefit the more than 1.8 million blind Americans. Commercially available TRCDs are expensive (~$12,000, or $19 per actuator), provide only one line of text (with 640 actuators) and ...
