Abstract: An apparatus, system, program product, and method are disclosed for determining the microstructure and properties of materials using acoustic signal processing. An apparatus includes a one or more sensors for sensing information describing a multiphase material using sound waves. The apparatus includes a processor operably coupled to the one or more sensors and a memory that stores code executable by the processor. The code is executable by the processor to receive sound-wave input from the one or more sensors, perform one or more quantitative analyses on the received sound-wave input in the frequency domain, and determine a microstructure of the multiphase material based on results from the one or more quantitative analyses.

Abstract: An apparatus includes an XY scanning mechanism, a first transducer configured to transmit a sound wave, a second transducer configured to receive the sound wave, and a tray configured to hold a material. The tray is coupled to the XY scanning mechanism and located beneath the first transducer and the second transducer is located on a bottom side of the tray below the material. The tray is moved in an XY pattern along an X axis and a Y axis in response to an XY scanning mechanism controller mechanically moving the XY scanning mechanism while the first transducer is positioned in a stationary location along a vertical axis perpendicular to the tray. The first transducer transmits sound waves into the material and the second transmitter receives the transmitted sound waves at each XY position.

Abstract: A method for determining a pathology of a tissue sample. The method includes steps of coupling the tissue sample between two oppositely-facing ultrasonic transducers; acquiring a pulse-echo ultrasonic measurement and a through-transmission ultrasonic measurement of the tissue sample using the ultrasonic transducers; analyzing at least one of the pulse-echo ultrasonic measurement and the through-transmission ultrasonic measurement using time domain analysis; analyzing at least one of the through-transmission ultrasonic measurements and the pulse-echo ultrasonic measurements using frequency domain analysis; and determining the pathology of the tissue sample based on at least one of the time domain analysis and the frequency domain analysis.

Abstract: A radiation detection, localization, and identification system uses a searching algorithm to identify hypothetical solutions to Compton scatter data. Model based representations of the physical data collection yield the location of radiation sources when suppressed correlations of source location are identified in processed event data. The system's detector is an array of radiation detectors networked to act as a single detection system. This network has wide area of view and high sensitivity to radiation sources since no collimation is required.

Abstract: A scanning system (10) for inspecting a surface (16) including a light source (30) which generates a beam of light (32) that is reflected, scattered or causes fluorescence at the surface to be inspected. An optical interface (14) receives the beam of light and directs it along a predetermined path extending to and from the surface. An acousto-optic tunable filter (34) tuned to pass light having a wavelength corresponding to a known optical property of a predetermined material is positioned within the path of light. A detector (42) is positioned to receive light emanating from the surface and is configured to monitor the intensity of light at each predetermined wavelength being monitored and generate a corrsponding signal. The system is preferably attached to a scan board (90) thereby enabling the system to be used in scanning a surface. The system also includes a signal processor (22) which processes the signal generated by the detector. The resulting data is displayed by an output device (26).

Abstract: An equatorial sundial according to this invention includes a dial surface and an elongated, rod-like gnomon fixedly secured in operative relation thereto. The dial surface is generally semi-cylindrical and concave toward the sun. The circumferential portion of the surface is further formed in the shape of a partial helix. The gnomon lies on the axis of the dial surface such that the longitudinal extent of the surface is transverse of the gnomon at an obtuse angle thereto. In a given geographical location, the sundial is so oriented relative to the earth that the gnomon is parallel to the earth's axis of rotation. With a proper pitch of the helical form of the dial surface, the opposite end portions thereof are offset in a direction parallel to the axis of the gnomon so that neither shade the dial surface either in the morning or evening.

Abstract: An adjustable loom comprising a first adjustable rectangular frame having two spaced, parallel, elongated, rigid uprights of substantially equal length. The uprights are longitudinally hollow. Two rigid, elongated, parallel extending leg members of substantially equal length are rigidly secured at the ends thereof to the lower ends, respectively, of the uprights. The leg members extend orthogonally from the uprights in the same direction. The leg members are also hollow. A first horizontal bar is rigidly secured at the opposite ends thereof to one side of the lower portions, respectively, of said uprights thereby providing a rigid framework of said uprights, leg members and bar. A second rectangular upright frame having two rigid frame elements telescoped into said uprights, respectively, has an elongated, horizontal bar rigidly secured at the opposite ends thereof to the upper ends of the frame elements.
