    Abstract: An apparatus, system, and related methods for multi-bounce material property detection and signal amplification are provided. The apparatus has a first acoustic transducer positioned on an exterior sidewall of a pipe or container carrying or holding a quantity of fluid therein. An acoustic signal is transmitted by the first acoustic transducer into the sidewall of the pipe from an exterior surface thereof. With material detection, at least a portion of the acoustic signal reflects off an interior surface of the sidewall of the pipe. The reflected acoustic signal is received at the second acoustic transducer on the exterior sidewall of the pipe. The reflected acoustic signal provides an indication of a material property of the pipe or a material within the pipe. With signal amplification, the second acoustic transducer transmits a phase synchronized second acoustic signal to the first acoustic signal to amplify the first acoustic signal.

    Abstract: A method using Infrared Imaging Polarimetry for detecting the presence of foreign fluids on water comprises estimating an expected polarization response for a foreign fluid desired to be detected. Oil from an oil spill is one such foreign fluid. An optimal position of a polarimeter to take images of the water's surface is determined from the expected polarization response. The polarimeter is positioned at the optimal position and records raw image data of the water's surface to obtain polarized images of the area. The polarized images are corrected, and IR and polarization data products are computed. The IR and polarization data products are converted to multi-dimensional data set to form multi-dimensional imagery. Contrast algorithms are applied to the multi-dimensional imagery to form enhanced contrast images, from which foreign fluids can be automatically detected.

    Abstract: A method for enhancing an image for facial recognition comprises capturing an image of the face with a polarizer and correcting the polarized image for non-uniformity. Stokes Parameters S 0 , S 1 , S 2 are obtained by weighted subtraction of the polarized image to form Stokes images. DoLP is computed from the Stokes images, and facial recognition algorithms are applied to the DoLP image. A system for enhancing images for facial recognition comprises a polarimeter configured to record polarized image data of a subject's face, a signal processing unit and logic configured to receive and store in memory the image data from the polarimeter, calculate Stokes parameters from the image data, and compute a DoLP image from the Stokes parameters.

    Abstract: A fire detection system (100) combines a CO2 gas detector (14) with a smoke detector (2). Logic circuitry (400) combines the outputs of both detectors to minimize false alarms and provide a rapid response time. In a preferred embodiment the need for periodic cleaning is reduced. In a further preferred embodiment, two alarms indicative of two different types of fires, for example flaming fires and nonflaming fires are available. A map (810) of flaming fire and smoke may be assembled by the system to guide the firefighters. In a yet another preferred embodiment, a tentative fire alarm indication (222, 233) disables a local air conditioning system thereby helping to isolate and control any existing fire.

    Abstract: An in vivo method and apparatus for detecting an analyte in an individual. A sensor that includes a fluorescence reagent is placed in communication with the body fluids of the individual suspected of containing the analyte in such a way that once in place said sensor does not exit the skin of the individual. The sensor is configured to retain the fluorescence reagent while allowing analyte to diffuse into and out of said sensor. The sensor is illuminated transdermally, and the fluorescence from the fluorescence reagent associated with the presence of the analyte is measured.
