Abstract: The present invention is a tomographic reconstruction algorithm, which is highly effective improving image quality and accuracy by reducing or eliminating artifacts within images produced by limited data tomography. Using algebraic reconstruction techniques (ART), depending on whether or not an object has higher or lower densities, a current threshold value is set to either a high or low threshold parameter and then decreased or increased, respectively, to reduce or eliminate the artifacts in a reconstructed image.

Abstract: A system for packaging and dispensing fluids including a flexible package having a removable margin portion and retention elements by which a tube may be held in a certain position within the package such that, when the removable margin is detached and pressure is applied to the exterior surface of the package sides, the dispensing end of the tube is indirectly pushed out from within the package inner volume and above the margin of the package for sanitarily dispensing fluid and, upon release of the pressure, the tube may slide back within the inner volume for the sanitary storage of the tube.

Abstract: A system by which the torque applied to a fastener such as a bolt or nut may be measured simply and accurately. More particularly, the invention relates to apparatus and methods by which the torque applied to a fastener by a socket wrench can be measured through a simplified extension element accurately and displayed quickly so that the placement of possibly damaging excessive amounts of pressure on the fastener can be avoided.

Abstract: An apparatus for controlling the position of a door suitable for use in association with door closing piston assemblies having a spring-biased reciprocable door closing piston rod and a latch plate transversely slidable along the length of the piston rod. By use of the present invention, a momentary initial rotational bias may be imparted to the latch plate automatically and electronically, thereby causing it to shift the latch plate towards a rotated angle while the door is closing, and to facilitate pre-positioning the latch plate to set into a locking hold-open orientation without any subsequent manual adjustment.

Abstract: A fluid detection system by which the presence or absence and identity of fluids may be detected within confined areas, such as those existing within underground storage tank systems and in which fluids may accumulate. The fluid detection system includes a probe assembly having circuitry which determines the presence of fluids by the capacitance developed across a variable capacitor. The output signal provided by the capacitor is converted to frequency values, is filtered by a receiver included with the system, and transmitted to a remote location for display. The system is suitable for deployment within and monitoring of one or a multiple of tank systems.
