A sample inspection apparatus includes a source of electromagnetic radiation, a beam former for producing a plurality of coaxial and substantially conical shells of radiation, a detection surface and a set of conical shell slot collimators. Each conical shell has a different opening angle. The detection surface is arranged to receive diffracted radiation after incidence of one or more of the conical shells upon the sample to be inspected. The set of conical shell slot collimators is provided at or close to the detection surface which each stare at different annular regions of different corresponding conical shells.

An on-body injector system includes a drug container assembly including a container, a seal member, and a sealing interface between the seal member and the container. The container includes an opening and the seal member at least partially covers the opening in the container. A fluid pathway assembly is coupled to the drug container assembly and includes a needle that is movable between a storage position, in which a point of the needle is spaced from the seal member, and a delivery position, in which the point of the needle is disposed at least partially through the seal member. A radiation generator is configured to emit rays of radiation to sterilize and/or disinfect the sealing interface. A barrier is disposed adjacent to the sealing interface and has an opening. At least a portion of the drug container assembly is positioned adjacent to the opening in the barrier.

Systems and methods for measuring the concentricity of golf balls using filter pairs to gather and analyze data on concentricity.

A Sterilization Unit includes: a UV-C radiation source configured to emit UV-C radiation; and a room partition selectably configurable between two or more different partition geometrics and configured, in each of the two or more different partition geometrics, to (a) physically separate floor space of a room into sterilization target area and a non-target area, and (b) direct the UV-C radiation to the target area from at least two different directions while shielding the non-target area from the UV-C radiation.

A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.

A defect inspection system includes an X-ray generator that generates X-ray to be irradiated to a structure, and an X-ray detector that detects the X-ray generated by the X-ray generator and transmitted through the structure. In particular, the X-ray generator is configured to be moved by a first transporting means, and the X-ray detector is configured to be moved by a second transporting means. The system further includes a control unit configured to control and operate the first transporting means and the second transporting means.

A method of investigating a specimen using tomographic imaging, comprising the steps of providing a specimen and a source, directing a beam of radiation from said source to said specimen, and detecting a flux of radiation transmitted through said specimen. The method further comprises the steps of moving at least one of said specimen and said source for providing relative motion of the source with respect to the specimen; and imaging the specimen along a series of different viewing axes, which intersect a virtual reference surface that surrounds the specimen and is substantially centered thereon, wherein said combined steps of moving and imaging generate a sampling geometry on said virtual reference surface. As defined herein, the steps of moving and imaging are coordinated in such a way that said sampling geometry comprises a plurality of spaced apart line segments.

A system can have an x-ray source that generates a series of individual x-ray pulses for multi-energy imaging. A first x-ray pulse can have a first energy level and a subsequent second x-ray pulse in the series can have a second energy level different from the first energy level. An x-ray imager can receive the x-rays from the x-ray source and can detect the received x-rays for image generation. A generator interface box (GIB) controls the x-ray source to provide the series of individual x-ray pulses and synchronizes detection by the x-ray imager with generation of the individual x-ray pulses. The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.

Techniques including methods, apparatus and computer program products are disclosed. These techniques include computer instructions that are encoded on computer storage media for determining wettability. The techniques use a numerical aging computation process to provide a representation of a wettability alteration of a physical rock sample in the presence of at least two fluids is disclosed. The techniques include retrieving a representation of a physical rock sample, the representation including pore space and grain space data corresponding to the physical rock sample, calculating local curvature for each surface in the pore space, determining from the calculated local curvature whether water-film breakage will occur, and classifying the wettability of the physical rock based on the determination of water-film breakage.
