The acoustic-intensity calculating unit calculates an acoustic intensity, in which an acoustic intensity caused by hammering on an inspection target at a hammering position is canceled out, based on audio signals acquired by microphones in a symmetrical arrangement of at least one pair of microphone positions with respect to the hammering position or in a symmetrical arrangement of two hammering positions with respect to a pair of microphone positions. The noise calculating unit calculates a noise component from the calculated acoustic intensity. The noise removing unit removes the noise component from a physical quantity based on at least one of audio signals acquired at the at least one pair of microphone positions. The inspecting unit performs inspection on the hammering position based on the physical quantity.

  • Patent number: 9618549
    Abstract: A spectrum analyzer contains a number of improvements that adapt it to common commercial uses. The spectrum analyzer is capable of automatically wirelessly receiving and synchronizing frequency spectrum data collected from multiple remote spectrum analyzers with respect to frequency, time and location. A selector function is used to create composite frequency data sets from multiple frequency data sets while allowing retroactive identification and examination of the original frequency data. An improved non-linear graphical display of the frequency spectrum data is created by automatically expanding the resolution of frequency axis for frequency ranges having signals of interest and contracting the resolution of the frequency axis of frequency ranges having no signals of interest.

  • Patent number: 9518891
    Abstract: Testing methods and equipment are provided for fast, non-destructive testing of the quality of seal and/or integrity of a package. According to certain embodiments, dynamic impact characterization is used to determine whether a loss of pressure due to a leak in the package occurs. The methods and equipment can be used in-line with product packaging processes. According to one embodiment, an initial pressure is applied to a package under test. A region of the package is impacted with a force sufficient to create a disturbance to the package while not destroying the package by using an impacting rod. Force sensors/transducers contact with the package and spaced a distance away from the impact region of the package detect a force signature from the impact. The existence of a leak is determined by evaluating the force signature.

  • Patent number: 9182434
    Abstract: A new rapid optical specific absorption rate (SAR) system is disclosed. The rapid optical SAR system has ability to measure and map the power deposited in a flat phantom or other phantom filled with a transparent simulant fluid. Absolute rates of temperature increase in the phantom by photo thermal techniques are measured. For example, the temperature increase and gradients in the phantom bend the path of a laser beam, which may be aimed at a position sensitive detector. The spatial SAR may be mapped and SAR differences between different telephones and telephone orientations, for example, can be distinguished. The system is non-invasive and non-perturbing of the SAR distribution in the phantom, can measure at locations up to the interior surface of the phantom, and provides thermally-based SAR measurements that do not necessarily require constant calibration.

    Abstract: A package testing system or apparatus that may be mounted directly onto an F/F/S machine and allows for communication with an F/F/S machine in the form of either a digital or analog signal. The communication may be implemented into a PID loop which allows for a predetermined burst pressure set point to be reached “automatically” by either the burst pressure controller or the F/F/S controller to automatically adjust the sealing parameters via the PID loop. The system may employ a novel sealing system that uses either a viscous solution or a series of laminated materials to seal either the needle entry point or the puncture side of the material in its entirety, thereby eliminating the use of known sealing patches that cover the porous webbing in testing. Methods for conducting such testing and for operating such systems are within the scope of the present disclosure.

An external signal is generated by a signal generator. Receive and transmit an external signal to an actuating unit by the signal input terminal so that the actuating unit has a vibration. Prompt a flexible portion by the actuating unit to produce a first resonant motion when the actuating unit having the vibration. The first resonant motion converts into a second resonant motion because the flexible portion is subject to a damping force of ambient air. Prompt a sensor unit by the second resonant motion to cause a shape transformation of the sensor unit to generate a detecting signal. Output the detecting signal to an external instrument by a signal output terminal of sensor unit to calculate a vacuum pressure value.

  • Patent number: 7980136
    Abstract: The leak and contamination detection micro-submarine includes an “electronic ear” and an “electronic nose” for detecting both leaks and chemicals within a pipe which may be leaking. The submarine includes an on-board electric motor which is radio remote controlled and may operate, or swim, in a manner similar to a fish using piezoelectric micro-motors and the like. Contamination, leak and other related data is stored in on-board memory and summary reports may be transmitted via RF signals.

  • Patent number: 7934415
    Abstract: A hydrostatic testing tool for testing containers, hoses or the like under high pressures. The testing tool having a coupling that threadably engages a threaded aperture of a test container without having to be rotated into the threaded aperture. The hydrostatic testing tool may be hooked up to a source of pressurized medium and the tool includes a container-engaging head having a plurality of collet segments that each have a threaded surface that can expand radially outward, partially due to the force of the pressurized medium, to engage a threaded aperture of the test container, allowing for the formation of a liquid and/or gas tight seal under high pressures. The testing tool further includes an actuating unit connected to the head that controls the movement of the collet segments with a piston or the like.

  • Patent number: 7748098
    Abstract: The present invention is for a method of testing a seal on a collapsible tube dispensing orifice during the manufacturing process in an assembly line. Air pressure is applied within the tube wall, at a station in the line, on one side of the seal, and the pressure is monitored on the other side of the seal within a reciprocating cover, for any increase in pressure which would indicate a leak in the seal.

  • Patent number: 7673491
    Abstract: A method of making an easy open end for a container includes steps of providing a can end blank having an end panel and forming the can end blank in a series of forming operations that are performed with specialized and unique tooling. The can end is preferably shaped during the forming operations so that a major portion of the end panel is curved. Specifically, the curvature is preferably such that a top surface of the major portion is generally concave and a bottom surface of the major portion is generally convex. The end panel is also preferably shaped and constructed so that the curved major portion will invert in shape upon the application of a sufficient predetermined pressure differential between the top and bottom surfaces. A method of testing a fill level of a sealed container is performed in reliance on this “cricketing” or “oil canning” effect.
