Abstract: The invention features a skin-piercing device having a piercing element and the use thereof of treating acne.

Abstract: A skin treatment article comprising a first side, a second side and edges provides customizable tactile stimulation. The first side comprises a plurality of lines extending between the edges having a thickness of about 0.1-2 mm and a spacing of about 1-20 mm.

Abstract: A fuel delivery system for a gas turbine engine includes a main fuel pump supplying fuel to a fuel-metering device. The operational flow range of the fuel system is dependent on a minimum net positive suction pressure at the main pump inlet required to prevent pump cavitation. A mixture of fuel and dissolved gases increases the minimum net positive suction pressure required to prevent cavitation. A fuel de-aerator including a permeable membrane removes dissolved gases from the fuel to eliminate formation of dissolved gases. The elimination of dissolved gases from within the liquid fuel reduces the required net positive suction pressure, enabling a greater operational flow range.

Abstract: An automated system and/or method is disclosed for rapidly, accurately, and efficiently processing bulk three-dimensional digital image data of both path/corridor and area scenes to discriminate different structures or classifications of objects from within the image. The method first decomposes the three-dimensional digital imagery coordinate points into simple local structures and then extracts the globally complex structures from the local structures. The system and/or method incorporates procedures for sub-dividing the three-dimensional image data into rectilinear and/or ellipsoidal finite element cells, mathematically analyzing the contents (point coordinates) of each individual cell to classify/define the local structure, and extracting the globally complex structure or object from the image.

Abstract: A method for demonstrating breathability by providing an aliquot of liquid in a container having an opening; forming a closed system by securing a film about the opening; imparting evaporation on the closed system; and measuring or observing the remaining fluid after a predetermined time.
