Abstract: A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate apertures of ultrasound arrays. Some embodiments provide systems and methods for designing, building and using ultrasound probes having continuous arrays of ultrasound transducers which may have a substantially continuous concave curved shape in two or three dimensions (i.e., concave relative to an object to be imaged). Other embodiments herein provide systems and methods for designing, building and using ultrasound imaging probes having other unique configurations, such as adjustable probes and probes with variable configurations.

Abstract: A putty paint compound for marking on a substrate, and a method and system of manufacturing a putty paint compound for marking on a substrate, are provided. In embodiments, the putty paint compound has a putty-like consistency that provides a delivery system for dye. In embodiments, a dye is dispersed into an elastic, pliable compound that maintains a putty-like form. When the compound is applied to a substrate having an activator, the dye dispersed in the compound creates a marking on the substrate that corresponds to the shape of the compound contacting the substrate. In further embodiments, the shape of the putty paint compound may be manipulated to provide a desired marking on a substrate, which may be altered by repeated or varied applications of one or more putty paint compounds.

Abstract: A roller ball pen for use with metallic inks, and a method for assembling the roller ball pen for use with metallic inks, is described herein. The pen body includes a housing that encloses a reservoir, a collet, a feed rod, and a tip. The feed rod transfers ink from the reservoir to a roller ball tip at a tapered end of the pen housing. In embodiments, the feed rod is embedded at a threshold distance inside the reservoir to provide an increased surface area for transfer of a metallic ink suspension. In further embodiments, a method of assembling the roller ball pen includes saturation of the reservoir with a metallic ink based on inserting a particular injection needle at a particular depth inside the reservoir.

Abstract: A gas turbine engine control system which receives an engine condition and generates a parameter signal representative of the condition. The control system also receives a temperature signal representative of the engine temperature downstream of the engine combustor. A comparator is used to compare the parameter signal with the temperature signal and a nonrecoverable stall output signal is produced when the temperature signal indicates the temperature is greater than a scheduled value for the given parameter signal. The invention also includes a method for monitoring a gas turbine engine comprising the steps of receiving an engine condition and for generating a parameter signal representative of the condition.
