Abstract: A computing device that provides hardware conversion of flow control predicates associated with program instructions executable within the computing device, detects the beginning and the end of a branch domain of the program instructions, and realizes the beginning and the end of the branch domain at execution time, for selectively enabling and disabling instructions within said branch domain.

Abstract: A fluorescent fiber-optic biosensor system using ultrasonic concentration of particles and cells for the detection of Salmonella typhimurium. A biosensor test chamber serves as an ultrasonic standing-wave cell that allows microspheres or cells to be concentrated in parallel layers or in a column along the axis of the cell. A fiber probe along the axis delivers laser excitation to fluorescent-labeled antibodies of Salmonella and collects the fluorescent signal. The Salmonella-antibody complexes are moved acoustically to the axis of the cell, increasing the fluorescent signal. Alternatively, the Salmonella-labelled antibody complexes attach to unlabeled antibodies that have been immobilized on the surface of polystyrene microspheres. This entire structure can be manipulated acoustically and the increase in the fluorescent signal, which can be an order of magnitude, indicates the presence of Salmonella.
