Abstract: A sample fluid (14) is pumped through a first cavity (38) associated with a first piezoelectric resonator (20.1) and pumped through a second cavity (40) associated with a second piezoelectric resonator (20.2). An electrode (26) of the first piezoelectric resonator (20.1) exposed to the sample fluid (14) in the first cavity (38) is coated with an adsorption layer (34.1) that provides for adsorbing a substance (12) to be detected in the sample fluid (14). The adsorbed substance (12) changes the resonant frequency of the first piezoelectric resonator (20.1) relative to that of the second piezoelectric resonator (20.2), wherein a change in the frequency difference therebetween relative to an initial frequency difference is responsive to and provides a measure of the mass of adsorbed substance (12). The adsorption layer (34.1) of the first piezoelectric resonator (20.1) is automatically refreshed when a change in the frequency difference crosses a threshold (?FEOR).

Abstract: A method used to predict a strength of an ultrasonic weld-joint of a wire-cable comprising the steps of providing a wire-cable, determining a combined-weight, removing a contaminant, determining a weight, determining a percentage by weight of the contaminant, and determining whether the percentage by weight of contaminant is less than a threshold. Determining the percentage by weight of the contaminant removed from the wire-cable is based on a formula [(Mb?Ma)/Mb]*100, where Mb is the combined-weight of the wire-cable and the contaminant and Ma is the weight of the wire-cable. The threshold of the percentage by weight of the contaminant correlates to the strength of the ultrasonic weld-joint.

Abstract: A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.

Abstract: A system for measuring corrosion and corrosion-erosion rates in a high temperature, high pressure multiphase dynamic environment includes a plurality of ring-shaped test coupons disposed within a test vessel in a vertical arrangement relative to one another. A test fluid mixture is added to the vessel and the temperature and pressure are maintained such that the mixture exists in a multiphase condition that has a vertical stratification such that each test coupon is exposed to a different phase and/or combination of phases of the fluid. Impellers can be used to stir the fluid to provide a dynamic environment. The fluid can include particulate matter to simulate real world test conditions. Separator plates can be disposed at different vertical locations within the vessel to maintain separation between various phases of the fluids and further restrict particulate matter from migrating between sections of the test system.
