摘要： An acoustic emissions testing device includes a testing sample, an acoustic sensor communicably coupled to the testing sample, and a load that is exerted on the sample. The acoustic sensor detects one or more acoustic events occurring within the sample. The acoustic sensor transmits data to a data recorder, which includes a processor and storage medium for executing instructions provided by a software residing within the storage medium. Upon executing the instructions on the transmitted data, the toughness of the sample is objectively determined and can be ranked comparatively to the toughness of other samples. The instructions provide for categorizing the data into possible acoustic event points and background data points, interpolating a background noise curve, determining the actual acoustic event points, and calculating the area under each actual acoustic event point.

摘要： The present invention allows even soft tissue such as body tissue having a hierarchic structure of skin, fat, muscle and bone, etc., to be estimated and allows estimation only through a short-time pressing operation to thereby reduce damages to the soft tissue. The present invention is constructed of an ultrasonic probe for transmitting/receiving an ultrasonic signal, a target deformation amount calculation section for calculating an amount of deformation of a target shape from a time variation of data received from the ultrasonic probe, a movement mechanism for moving the ultrasonic probe, a probe control section for controlling the probe, a position sensor for measuring the position of the probe, a force sensor for measuring a force applied to the probe section, a viscoelasticity estimation section for estimating viscoelasticity of the target based on values obtained from the position sensor, force sensor, target deformation amount calculation section and a viscoelasticity display section for presenting the estimated viscoelasticity to the user.

摘要： Apparatus for measuring the hardness properties of materials may comprise: a frame for supporting the apparatus and the material to be tested; a test head assembly mounted on the frame for applying predetermined measuring forces to the material and a clamp assembly mounted on the frame for supporting the material and for applying a clamping force to clamp the material against the tester head assembly prior to application of the predetermined measuring forces. The tester head assembly may include a housing; a penetrator assembly carried by the housing, including an axially reciprocal penetrator shaft at the lower end of which is a ball member for contact with the material; an operating assembly for applying a first predetermined force and a second and greater predetermined force to the penetrator shaft for indentation of the material by the ball member, and indicating devices for measuring the difference of indentations of the material by the first and second predetermined forces. A load cell may be attached to the penetrator shaft for measuring the first and second predetermined forces, for controlling the operating assembly by which the first and second predetermined forces are applied to the penetrator shaft, and for reporting load to the control panel.
