Abstract: A breast phantom is provided that has a non-uniform thickness to mimic clinically realistic variations in compressed breast thicknesses when in contact with the compression paddle during a mammography imaging procedure. With the non-uniform thickness, the breast phantom enables a mammography imaging device to be tested for image quality with regard to image correction processes and/or algorithms employed by the mammography imaging device to address non-uniformity in the thickness of the imaged breast. The breast phantom can be made of one or more sections, with one or more of the sections having a non-uniform thickness.

Abstract: A system may receive, from one or more data sources, one or more de-identified data sets that include de-identified personal data. The system may receive a request for a feature set of the one or more de-identified data sets, wherein the feature set includes a set of quasi-identifiers included in the de-identified personal data. The system may calculate a re-identification risk score for the set of quasi-identifiers. The system may selectively output, based on the re-identification risk score, one of: actual data, from the one or more de-identified data sets, of the feature set if the re-identification risk score satisfies a condition, or synthetic data, generated by the device from the one or more de-identified data sets, for the feature set, or a combination of the synthetic data and the actual data for the feature set, if the re-identification risk score does not satisfy the condition.

Abstract: A bi-stable brake actuator is provided and includes a fixed core movable in a first direction, a coil disposed in the fixed core and configured to generate magnetic fields of opposite polarities when supplied with opposing currents, respectively, a movable core disposed to move between retracted and extended positions with respect to the fixed core and the coil in exclusively a second direction defined orthogonally with respect to the first direction and a permanent magnet assembly. The permanent magnet assembly is disposed to move between first and second positions in accordance with the coil being supplied with the opposing currents, respectively.

Abstract: An actuation mechanism for an elevator safety gear comprises an engagement element, at least two permanent magnets and at least one electric coil. The engagement element is movable between an engaged position in which it engages with the guide member of the elevator system and a disengaged position in which it does not engage with the guide member of the elevator system. The at least two permanent magnets are arranged in a configuration generating a repulsive force (FR) between the at least two permanent magnets and urging the engagement element towards the engaged position. The at least one electric coil is configured for generating an electromagnetic force urging the engagement element towards the disengaged position and/or for holding the engagement element in the disengaged position, when an electric current is flowing through the at least one electric coil.

Abstract: An elevator safety gear actuation device for actuating an elevator safety gear comprises a first member and a second member. The first and second members are arranged opposite to each other defining a gap configured for accommodating a guide member extending in a longitudinal direction. At least one of the engagement members comprises an engagement element which is movable in a direction transverse to the longitudinal direction between a disengaged position and an engaged position. The first engagement element comprises at least one permanent magnet which is configured for being magnetically attracted and attaching to the guide member extending through the gap when the engagement element is arranged in the engaged position. The second member comprises at least one additional permanent magnet which is configured for being magnetically attracted to the guide member extending through the gap.

Abstract: A technique facilitates coupling of sections of tubing, e.g. a casing and a liner. A first tubing is positioned at a desired location, and then a second tubing is deployed through an interior of the first tubing until predetermined regions of the first tubing and the second tubing are in proximity to one another. A molten metal material is located between the first tubing and the second tubing at the predetermined regions. The molten metal material is then solidified to secure the second tubing to the first tubing.

Abstract: An anchor device is utilized to locate the whipstock both longitudinally and rotationally in order to properly orient the whipstock prior to beginning the sidetrack operation. In order to hydraulically set the slips a hydraulically actuated piston in a hydraulic cylinder is pressurized to overcome a restraint such as a shear pin thereby releasing a spring that drives a second piston to force the slips radially outwards thereby setting the anchor. In certain instances the anchor may also be set down on a rod that is also attached to the hydraulic piston. By setting down on the rod the shear pin is also overcome which also releases the spring.

Abstract: A folder that provides an improvement in protection of papers in an easier and handier way, having slots, which are located in any of its backs, either in the corners or in any part of the edges, these slots allow us to hold documents in all the corners, locking the folder this way. This feature allows us to eliminate mechanisms and additional objects that perform these functions, so we obtain a simple and useful folder that prevents papers from falling or coming out, since it is vital to protect papers.

Abstract: An orifice fitting seal assembly is provided for use in an orifice fitting having a body structure defining a flow passage and opposed spaced sealing surfaces surrounding the flow passage. The improvement comprises a pair of internal seal rings of symmetrical configuration which cooperate to define a plate receptacle within which an apertured orifice plate is positioned. Each of the internal seal rings defines peripheral locking flanges that are disposed in spaced relation when the rings are in assembly. An external locking ring surrounds the assembled internal seal rings and establishes locking engagement therewith to retain the internal seal rings and the orifice plate in assembly. A pair of inner O-ring type sealing elements are retained within internal sealed grooves defined by each of the internal seal rings and the orifice plate.
