Patent number: 8789419Abstract: An apparatus and method for ultrasonic non-destructive testing provides an elongate strip of ultrasound transmissive material coupled at a proximal end to an object under test. The elongate strip has a transverse cross-section with a width and thickness giving an aspect ratio greater than unity and matched to the ultrasonic transducer such that excitation induces a substantially non-dispersive ultrasonic signal to propagate along the elongate strip to the proximal end and to enter the object under test. These non-dispersive pulses are particularly suited for time-of-flight measurements, thickness measurements, crack measurements and the like. The elongate strip helps to separate the transducer from a potentially hostile environment associated with the object under test. The elongate strip also has a large area of contact with the object under test allowing efficient transmission of energy into the object under test.Type: GrantFiled: December 12, 2012Date of Patent: July 29, 2014Assignee: Imperial Innovations LimitedInventors: Peter Cawley, Frederick Bert Cegla

Patent number: 8789425Abstract: A micromachined or microelectromechanical system (MEMS) based push-to-pull mechanical transformer for tensile testing of micro-to-nanometer scale material samples including a first structure and a second structure. The second structure is coupled to the first structure by at least one flexible element that enables the second structure to be moveable relative to the first structure, wherein the second structure is disposed relative to the first structure so as to form a pulling gap between the first and second structures such that when an external pushing force is applied to and pushes the second structure in a tensile extension direction a width of the pulling gap increases so as to apply a tensile force to a test sample mounted across the pulling gap between a first sample mounting area on the first structure and a second sample mounting area on the second structure.Type: GrantFiled: May 7, 2013Date of Patent: July 29, 2014Assignee: Hysitron IncorporatedInventors: Yunje Oh, Edward Cyrankowski, Zhiwei Shan, Syed Amanula Syed Asif

Patent number: 8789426Abstract: A system and method employing a piezoelectric sensor for quasi-static force measurement substantially free of drift and with improved low-frequency response. The output signal from the sensor is sampled and integrated using digital techniques that include a drift compensation algorithm. The algorithm continually monitors the sensor output and estimates bias errors that will cause the output to drift.Type: GrantFiled: August 15, 2011Date of Patent: July 29, 2014Assignee: Purdue Research FoundationInventors: Steven D. Pekarek, Kevin A. Rosenbaum

Patent number: 8789427Abstract: In an embodiment, a hydraulic jack is provided having a first portion and a second portion. The first portion attached to a first section of a structure and the second portion attached to a second section of the structure. When a pressurized fluid is forced between the first portion and the second portion, a load is transferred to the first section and the second section by the pressure of the fluid on the first portion and the second portion. The first section and the second section are forced apart by the load, thus creating or enlarging at least one void in the structure. The pressurized fluid fills or partially fills one or more of the at least one void, thereby increasing the surface area effectively normal to the direction of the load in contact with the pressurized fluid.Type: GrantFiled: May 20, 2013Date of Patent: July 29, 2014Assignee: Loadtest, Inc.Inventors: John A. Hayes, William G. Ryan, Nicholas K. Yankopolus
