The further development of a unique interferometric based optical biosensor platform for the rapid unlabelled detection and identification of foodborne pathogens was carried out under Phase II SBIR contract DAAD16-01-C- 0001 entitled: An Ultra-Sensitive Optical Biosensor for Food Safety. The potential in combining optical methods with biomolecular recognition techniques is the high signal gain derived from photonic amplification and thus high sensitivity, specificity, and rapid response time.
Centrifuges operating in a field environment need to be compact, light weight rugged and reliable. Available centrifuges have reliability issues related to the robustness of the mechanisms supporting the centrifuge rotor. The mass imbalance introduced on the rotor by asymmetrically loaded tubes aggravates this problem considerably. Use of magnetic bearings with no rubbing surfaces is a viable solution to reduce wear and increase reliability. Combining the magnetic bearing into the ...
New spacecraft designs feature large structures characterized by low natural frequencies and stringent pointing and vibration requirements. These large space structures pose unique and difficult control problems. These problems include system bandwidths greater than structural natural frequencies; lack of accurate information about the dynamic characteristic of the structure being controlled; complicated high-order dynamics, including non-linear behavior; and stringent requirements for distributed shape control. An important part of the solution to ...
