in the environment, such as toxins. These bacteria, however, are difficult to store, since they can survive only in a narrow range of environmental conditions. The inventors have genetically engineered spore-forming bacterial cells to detect substances. Spores permit the survival of bacteria in harsh conditions, so the genetically engineered bacteria of this invention can be stored in harsh environmental conditions.

Title: "System and technique for retrieving depth information about a surface by projecting a composite image of modulated light patterns" Inventors: Dr. Daniel Lau and Chun Guan (Electrical and Computer Engineering)
Technical Description: The invention relates to structured light systems that utilize multipattern techniques, whereby multiple projected structured light patterns are used to reconstruct an image. In particular, the invention relates to a technique and system that employ at least one camera and one projector used in concert for retrieving depth information about at least one surface of an object employing traditional, and new, structured light-pattern projections.
Summary: Extracting depth information from camera images or real-world objects is useful and has both and robotics or military applications. Current methods of extracting depth information from camera images are sensitive to
