    Abstract: A diagnostic gage (12) that can be implemented into a tissue-simulating headform (17) or other anthropomorphic surrogate test device (11) as a means of determining the internal strain within the test surrogate. One embodiment of the gage consists of a matrix or substrate embedded with x-ray contrast agents (14) and a series of holes within the substrate (15) that provide contrasting markers in an x-ray image and a means of intimately coupling the gage to the test specimen. The relative motion of these contrasting markers can be monitored using x-ray fluoroscopy equipment (e.g., source (10) and detector (13)). This gage provides a means of determining the internal strain within a headform surrogate model for the purpose of evaluating the performance of helmets in terms of reducing the occurrence of concussion among other biomechanical injuries from trauma.

    Abstract: Wireless strain and displacement sensors wirelessly monitor structural health and integrity, and are made by printing inductor-interdigital capacitor sensing circuits on a variety of substrates, including ceramic substrates, with thermally processable conductive inks. Sensors of the invention can be employed to detect strain and displacement of civil structures, such as bridges and buildings. The sensors include sensing elements that are mounted or printed on stiff, inflexible substrates, which prevent the sensing elements from bending, stretching, or otherwise warping when the sensor is strained. An interlayer between the sensing elements allows the sensing elements to move with respect to each other during application of strain. Thus, strain causes the sensing elements to move but not to deform, causing changes in sensor resonance that can be detected through wireless radio-frequency interrogation. Because the sensing elements do not change shape when under strain, the sensor can undergo millions of measurement cycles before breaking.

    Abstract: A method for inspecting masks used in x-ray lithography is described. An x-ray lithography mask is placed over a glass surface, followed by exposure of the mask and glass surface to soft x-rays. Portions of the mask absorb the soft x-rays while other portions of the mask, corresponding to circuit elements, allow the soft x-rays to strike the glass surface. The soft x-rays striking the glass surface cause the glass surface to darken, thereby forming an image of the circuit pattern in the glass surface corresponding to the stenciled circuit in the mask. An inspection of the image can reveal any defects in the x-ray lithography mask.

    Abstract: An apparatus which allows monochromatic radiographs to be produced using conventional "table top" Coolidge tube generated x-rays, comprises of the use of known bent crystal x-ray diffractive optics to produce radiographic images. The apparatus for producing the desirable x-ray radiation in a predetermined maximum intensity includes a crystal of the type mentioned above which focuses the x-rays emitted from the tube, the crystal and tube being mounted on a linear translation table. In addition, a method of mammography and differential angiography employing that device are presented. Resolution of mammographs are improved and the method which uses images obtained with radiation above and below the absorption edge of the dye being used to detect anomalies in a circulatory system allows the use of dramatically reduced dye concentrations.

    Abstract: An apparatus and method for determining the shape specific contraction and expansion of cylindrical or otherwise geometrically regular-shaped products as a function of time and temperature through high precision, continuous, nondestructive dimensional analysis of a cross-section of the object as the object is heated and/or cooled. The apparatus includes multiple penetrating radiation sources and detectors. In performing the analysis on an object as its temperature changes over a certain temperature range, the apparatus generates curves or formulas representing the changes in a dimension of the object as a function of temperature and/or time.
