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.

The microarray modules are arranged to simulate or orient individual transducers in a hyperbolic paraboloid geometry.

Abstract: A system for predicting epileptic seizures includes sensors operable to record a wearer's brain activity. The sensors electronically communicate with a processor configured to receive and store output EEG oscillations and activities. A threshold electrical fluctuation level is identified as the level electrical activity experienced at the onset of a seizure event, and is then stored in the PDA memory as a predetermined threshold value. The processor analyzes the input EEG data logged for a recording period, and the logged data is broken into a number of data values across a series of individual set sampling periods. Convert collected data value readings for individual sampling periods as a non-linear measure value using fractal dimension, P&H and/or Lyapunov weighing. The calculated values for a predicted next time intervals extending the sampling period is projected forward and compared against the predetermined threshold value to indicate a likely seizure event.

Abstract: An ultrasonic device evaluates the sound velocity of a nail to determine the overall health of a patient and to monitor cosmetological effects of certain products on the nail. The ultrasonic device includes a handhold probe having an piezoelectric transducer encased in cover that emits high-frequency ultrasonic impulses directed towards the nail. The nail reflects returning ultrasonic echoes back to the piezoelectric transducer. The returning ultrasonic echoes vibrate the piezoelectric transducer. A processor of a computer converts the vibrations into electrical pulses. The processor evaluates amplitude values of the electrical pulses to determine the parameters of the human nail, including the thickness, density and elasticity. The parameters are displayed on a display and analyzed by a technician to determine the nail condition. The health of the person or the effect of products on the nail can be determined based on the nail parameters.

Abstract: Surface modification methods based on a combination of plasma and chemical treatments render an unfilled butyl rubber surface highly reactive toward organosilanes, allowing formation of an organosilane self-assembled monolayer (SAM). Plasma oxidation of the butyl rubber surface followed by vapor deposition of SiCl4 produces a hydrophilic surface suitable for anchoring organosilanes. Fabrication of SAMs on this hydrophilic butyl rubber surface with n-octadecyltrichlorosilane (OTS) and trichloro(1H,1H,2H,2H-perfluorooctyl)silane (FOTS) via vapor deposition resulted in a 15% and 25% decrease in gas permeability, respectively, with no change in optical transparency of the butyl rubber.

Beneficial effects of the treatment have been observed at lower doses of CoQ10 than previously described.
