    Abstract: In a preferred embodiment, there is provided a method for determining a breathing pattern, the method comprising: placing a motion sensor and a flex sensor proximate to a diaphragm of a subject; obtaining time domain signals or data from both said sensors over a time period; subjecting the time domain signals or data from the motion sensor to Fast Fourier transformation to obtain frequency domain signals or data, and determining from the frequency domain signals or data one or more frequencies associated with body motion of the subject substantially unrelated to breathing; and filtering the time domain signals or data from the flex sensor to remove information related to the body motion therefrom to obtain filtered time domain signals or data.

    Abstract: An inspection probe and system for inspecting a welded or brazed joint includes a housing having an internal cavity and opposed tapered standoffs disposed at a distal end portion of the housing. Distal ends of the opposed tapered standoffs define pivot surfaces, and the opposed tapered standoffs are spaced apart to define a secondary enclosure. A plurality of transducer elements are disposed within the internal cavity of the housing and a primary coupling medium made of a flexible, semi-solid material is secured between the opposed tapered standoffs. A signal processing module is in communication with a data acquisition unit, which is in communication with the transducer elements. The inspection probe is rotated across the joint, data from the transducer elements is communicated to the signal processing module, and reconstructed and corrected images obtained at different angles from the transducer elements are stitched to generate an inspection image.

    Abstract: A method and apparatus for generating true random numbers is provided which is hardware based, and which uses unpredictable physical noise produced by an optoisolator. Specifically, the noises resulting from one or more of quantum shot, thermal noise, flicker, and the photoelectric effect are used as variable energy sources for subsequent conversion into a bitstream used for random number selection. The apparatus is preferably provided with a through hole prototype design and construction which requires minimal number of components reducing overall costs.

    Abstract: A sensor assembly including one or more capacitive micromachined ultrasonic transducer (CMUT) microarray modules which are provided with a number of individual transducers. The microarray modules are arranged to simulate or orient individual transducers in a hyperbolic paraboloid geometry. The transducers/sensor are arranged in a rectangular or square matrix and are activatable individually, selectively or collectively to emit and received reflected beam signals at a frequency of between about 100 to 170 kHz.

    Abstract: A plating bath for electroless deposition of gold and gold alloy layers on such silicon-based substrates, includes Na(AuCl4) and/or other gold (III) chloride salts as a gold ion source. The bath is formed as a binary bath solution formed from mixing first and second bath components. The first bath component includes gold salts in concentrations up to 40 g/L, boric acid, in amounts of up to 30 g/L, and a metal hydroxide in amounts up to 20 g/L. The second bath component includes an acid salt, in amounts up to 25 g/L, sodium thiosulfate in amounts up to 30 g/L, and suitable acid, such as boric acid in amounts up to 20 g/L.
