The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as a hole, crack, wrinkle, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting defect areas within the 3-D image in real time or near real time and providing data regarding each defect area, such as the depth, size, and/or type of each defect.

A sample testing cartridge is usable to perform a variety of tests on a viscoelastic sample, such hemostasis testing on a whole blood or blood component sample. The cartridge includes a sample processing portion that is in fluid communication with a sample retention structure. A suspension, such as a beam, arm, cantilever or similar structure supports or suspends the sample retention portion relative to the sample processing portion in a unitary structure. In this manner, the sample retention portion may be placed into dynamic excitation responsive to excitation of the cartridge and correspondingly dynamic, resonant excitation of the sample contained within the sample retention portion, while the sample processing portion remains fixed. Observation of the excited sample yields data indicative of hemostasis. The data may correspond to hemostasis parameters such as time to initial clot formation, rate of clot formation, maximum clot strength and degree of clot lysis.

A system and method for real-time measurement of curing energy delivered to a simulated dental restoration from a source of curing energy. The system comprises a detector and a display. The detector measures at a location within the simulated dental restoration the amount of curing energy delivered by the curing energy source. The display displays the measured amount of curing energy in real-time. The system also comprises a temperature detector to measure temperature changes in the oral tissues during curing (teeth and gums). The system also comprises a video camera to record the operator's curing technique.

The present invention relates to a method for determining mechanical parameters of a cementitious system, on the basis of time, and on the basis of the fineness of the cementitious system, pressure and/or temperature, representative of the in situ conditions found in wellbores. The initial composition of the cementitious system, the fineness thereof and the speed of the compression waves on the basis of time V.sub.p(t) are the only input data of the method. Said method comprises: .square-solid. a step A of estimating the degree of hydration of the cementitious system on the basis of time (t) from Vp(t), at a pressure P1 and a temperature T1; .square-solid. a step B wherein (t) is determined on the basis of desired values of fineness n of the cementitious system, pressure Pn and/or temperature Tn; .square-solid. a step C wherein the composition of the cementitious system is determined on the basis of time C(t) and on the basis of desired values of fineness n of the cementitious system, pressure Pn and/or temperature Tn from (t) determined in step B; .square-solid. and a step D of determining at least one mechanical parameter of the cementitious system on the basis of time and on the basis of desired values of fineness n of the cementitious system, pressure Pn and/or temperature Tn, from C(t) determined in step C. According to the method of the invention, these parameters can be determined while the cementitious system is still very young. In particular, the parameters of static deformability and hydro-mechanical coupling parameters are determined by the method according to the invention.

A method for monitoring a vulcanization process of a vulcanization mixture contained in a tool may include using an emitter to emit ultrasonic waves toward a boundary surface between the vulcanization mixture and the tool, wherein boundary surface reflects at least part of the ultrasonic waves. The vulcanization process may be monitored as a function of at least part of the emitted ultrasonic waves reflected by the boundary surface, wherein the ultrasonic waves include at least transverse waves generated by the emitter.

A method and apparatus for ultrasonic in-process monitoring and feedback of resistance spot weld quality uses at least one transducer located in the electrode assembly transmitting through a weld tip into an underway weld. Analysis of the spectrum of ultrasonic waves provides the operator with an indication of the size, thickness, location, dynamics of formation and quality of the spot weld.
