Abstract: An air-coupled ultrasonic plane stress detection method for a composite material based on dual-modal sound-time ratios of a Lamb wave includes: S1: assembling a detection device; S2: based on the detection device and the dual-modal sound-time ratios of the Lamb wave in S1, using unidirectionally loaded stress to obtain different stress coefficient relations; S3: based on the stress coefficient relations in S2, solving stress coefficients; S4: based on the stress coefficients in S3, acquiring three sound-time ratios; S5: based on the sound-time ratios in S4, describing a stress state of a detection point; and S6: repeating S4 and S5 till completing detection and scanning. The method improves the accuracy of stress coefficient calibration and air-coupled ultrasonic stress representation of a composite material panel greatly.

Abstract: The present disclosure provides systems and methods which facilitate the prediction of an estimated time in which one or more fluids will optimally be diffused into a biological specimen, e.g., a tissue sample derived from a human subject. In some embodiments, the present disclosure provides systems and methods which facilitate the prediction of an estimated time until a biological specimen will optimally be fixed with one or more fixatives. In other embodiments, the prediction of a future time at which the biological specimen will be optimally fixed is based on time-of-flight data acquired at a particular point in time during the fixation of the biological specimen that has been deemed sufficiently accurate to predict the time at which the biological specimen will be optimally diffused with fixative.

Abstract: A signal processing unit configured to: cause a first ultrasound emitter, when attached to a wall of a vessel, to emit a first ultrasound test signal; receive, from at least one ultrasound receiver, when attached to the wall of the vessel, the first ultrasound test signal; detect a time of flight of the received first ultrasound test signal; and determine that an acoustic coupling of the first ultrasound emitter and a first ultrasound receiver of the at least one ultrasound receiver to the wall of the vessel is intact if the detected time of flight corresponds to a length of a path in the wall of the vessel from the first ultrasound emitter to the at least one ultrasound receiver.

Abstract: Disclosed are a method of inspecting a printing quality of a 3D printing object using a femtosecond laser beam during a 3D printing process, and an apparatus and a 3D printing system for the same. A laser beam is irradiated from a femtosecond laser source disposed coaxially with a 3D printing laser source to inspect a state of the printing object. The laser beam generated by the femtosecond laser source is separated into a pump laser beam and a probe laser beam. The printing laser beam irradiated from a 3D printing laser source or the pump laser beam is irradiated onto a printing object to generate ultrasonic waves. To measure the ultrasonic waves, a probe laser beam is irradiated onto the printing object. The probe laser beam reflected by the printing object is detected. The quality of the printing object is inspected by analyzing the reflected probe laser beam.

Abstract: The present disclosure discloses a method of identifying delamination damage of an arc-shaped composite laminate, and belongs to the technical field of delamination damage identification. According to the method, an elliptical loci method and a fitted normal PDF for damage imaging are probabilistically integrated under a Bayesian framework. A plurality of characteristics sensitive to damage can be reasonably fused, known prior information is combined with measured time of flight (ToF) data, and the posterior distribution of unknown parameters is sampled by using a Markov Chain Monte Carlo (MCMC) algorithm, so that the reliability of damage location is improved, and the applicability of Lamb waves in damage location of plate structures is enhanced. In addition, the present disclosure can accurately identify the delamination damage of the arc-shaped composite laminate by processing the measured time of flight (ToF), and the absolute positioning error is less than 1 cm.

Abstract: A clamping element comprises a clamping body, such as a screw, having an ultrasound sensor fixed to the head. The sensor transmits and collects ultrasound that propagates along the shaft of the screw between two flat and parallel base surfaces, to measure a physical quantity connected to the clamping force that acts on the screw. A cap-shaped cover element can be removably affixed to the screw head and houses a wired or wireless communication module, a controller, power supply means, and possibly additional sensors. A memory can be stably fixed to the ultrasound sensor to store screw-characteristic data. A monitoring system can collect and process the data of all the clamping elements with a single processor.
