Abstract: A method and an apparatus are provided for measuring the thickness of a coating material using ultrasonic signals. A broad band of frequencies is transmitted by a transducer towards a layer of coating layer on a substrate and a trailing signal is received from the coating layer/substrate interface while a leading backscattered signal from a fluid/coating layer is gated out. The trailing signal is deconvolved into a set of frequencies. The resonant frequency of the coating layer is determined as the frequency with the greatest amplitude. The thickness of the material is calculated as a function of the resonant frequency of the coating layer.

Abstract: A shock tube comprises a driver section, an expansion section connected to the driver section, and an extension connected to the expansion section. Shock absorbent material is disposed within a cavity defined by the driver section and extension section. At least one active vent is disposed over respective holes in the extension section that are connected to the cavity. The extension section is adjustable between one of at least two positions such that a length of the extension section in a first position is longer than a length of the extension section in a second position. The length of the gas column contained within the driver section can also be adjusted by the position of a movable bulkhead.

Abstract: An apparatus for detecting and processing impacts to an electronic percussion instrument is disclosed. The apparatus includes a pad for being impacted with an impact pressure at an impact point, and several sensors. One sensor is located in close proximity to the pad for producing a first output value corresponding to the impact pressure, and another sensor located in close proximity to the pad for producing a second output value corresponding to the impact point and the impact pressure. A processor determines a computed impact point from the first and second output values, and controls output sound in conformance with the computed impact point.

Abstract: A method and apparatus for the accurate monitoring of a granule during compression testing is provided and enables the study of breakage mechanisms that cause particle failure during compression. The method involves compressing a granule or particle with the apparatus and the apparatus is a spring device that combines a spring in parallel with the granule or particle and a spring in series with the granule or particle. Under failure conditions, sudden deformation of the granule or particle results in fast relaxation of the granule or particle during breakage and allows very careful granule breakage. Measuring or recording devices coupled to the apparatus provide for the detailed study of breakage conditions at the moment of failure and lend incite into the compression strength characteristics of the granule or particle.

Abstract: A damage detection device is used to detect damage in bonded and laminated composite structures. A tap hammer or tap coin containing an acceleration sensor is connected to a circuit that can measure the width of an impact signal and then display the result. The result correlates to local stiffness of a structure. A method of determining the desired signal width and the method of using the damage detection device, includes tapping a known good region and then tapping a suspect region. Readings from the two areas are used to determine whether the suspect region is within an acceptable range. The circuit determines the desired signal width by measuring from the time the impact signal exceeds a threshold to the time it falls below the threshold.
