摘要： A computed tomography (CT) image quality phantom for use in calibrating explosive detection systems (EDS) at airports. A foam core block containing up to five right cylinder rod members is positioned in a housing member which is adapted to be passed through an airport luggage scanning machine. The rod members are of different lengths in order to create different data slices for analysis. The housing has a lead-in member at least at one end in order to allow passage through an EDS more easily and provide accurate CT calibrating.

摘要： A patch and associated methods for monitoring and inspecting a structure are provided in order to facilitate such inspections. The patch includes a sheet of material configured to be attached to the structure and a frequency steerable array carried by the sheet of material. The frequency steerable array includes a plurality of sources for emitting structural waves in response to an input having a variable frequency such that variations in the frequency of the input cause the structural waves emitted by the plurality of sources to be controllably steered relative to the sheet of material. Methods utilizing one or more frequency steerable arrays for monitoring and inspecting a patch-repaired structure are also provided.

摘要： A system for measuring a mixture ratio associated with a two-part fluid, at least one of the two parts including conductive particles. The system includes a pair of electrodes, a circuit, and an output. The electrodes are disposed on opposite sides of the two-part fluid and sense the dielectric strength of the fluid. The circuit communicates with the electrodes to sense the dielectric strength and outputs a signal representing the dielectric strength. Preferably, the circuit includes a capacitive bridge, an input for a set-point, and an output for an error signal. Also, the system can include a housing for the electrodes. A timer may also be provided to measure the time elapsed from the beginning of the mixing of the two-part fluid. Preferably, the two-part fluid is an adhesive with aluminum particles that is made from a resin and a hardener. Methods of producing two-part fluids are also provided.

摘要： A method and apparatus are provided to identify unacceptable levels of porosity, microcracking or defects attributable to thermal damage. Ultrasonic signals are introduced into the workpiece, such as by means of an ultrasonic transmitter. The ultrasonic signals propagate along a predefined axis of propagation oriented at an offset angle relative to a predefined reference direction oriented normal to the workpiece. Backscattered signals are received, such as by an ultrasonic receiver, from the workpiece. A measure representative of the cumulative energy of the backscattered signals received over a predefined time interval is then determined, such as integration performed by a processing element. An anomalous response may then be detected based upon the measure representative of the cumulative energy of the backscattered signals. This anomalous response may be representative of at least a predefined amount of porosity, microcracking or thermal damage.
