Force lines

Abstract: The present invention is directed towards an improved system and method for visualizing and quantifying data associated with biological curvilinear/tubular structures such as the gastrointestinal tract. In the present invention, an electrical field based approach provides a system and method to unravel convoluted biological curvilinear/tubular structures such as the colon. The approach digitally straightens or flattens such structures with curved cross-sections. Electrical charges are simulated along the structure's central path. Each curved cross section of the colon is defined by electrical force lines due to charges distributed along the colon path, and constructed by directly tracing the force lines. In a further embodiment, the efficiency of the unraveling is improved by directly tracing only representative force lines that originate equiangularly from the current colon path position. The other force lines are interpolated from the traced force lines.

Abstract: The present invention discloses method and apparatus for connecting together two members having mating surfaces by means of a plurality of fasteners such that equal compression forces are exerted on the members along force lines normal to a common plane. To accomplish the foregoing objectives, a plurality of pins are carried by one member and pass through bores in the opposite member. The pins are longitudinally extended simultaneously with a common internal extending force and stops are affixed to the ends extending through the second member snugly against the surface thereof. Upon release of the common extending force, all the pins attempt to restore to their original positions with equal restorative forces being equal and opposite to the common extending force applied thereto.

Abstract: A new method for constructing an optical image of the configuration of magnetic field lines using a ferrofluid cell with a magnetic fluid is considered. The carried out experimental researches have shown that the proposed method allows to determine the volumetric inhomogeneity of the field in the magnetic system. It is shown that the optical image can be used in real time to adjust the magnetic system to the minimum induction values ΔB in three planes.

Abstract: A new method for studying the structure of the field lines of the magnetic systems of various configurations. The optimum parameters of ferrofluid cells and laser light for different research variants of force lines structure in the area between the poles of the magnetic system are determined. The results of experimental studies, which allow to define the change ΔB inhomogeneity of the magnetic field over the cross section of the magnetic system and to carry out its adjustment to the minimum ΔB in real time are represented.
