  • Publication number: 20240191817
    Abstract: A magnetic coupling system that includes a first housing disposed about an end of a first conduit. The first housing includes an axially-extending annular flange. A first annular magnetic element, coupled to the first housing and concentric with the annular flange, has a first plurality of magnetic polarities disbursed thereabout. A second housing, disposed about an end of a second conduit, includes an axially-extending annular channel for engagement with the annular flange. A second annular magnetic element is coupled to the second housing and is concentric with the annular channel. An air gap is disposed between the first annular magnetic element and the second annular magnetic element when the annular flange is engaged in the annular channel. The second annular magnetic element has a second plurality of magnetic polarities disbursed thereabout.

  • Publication number: 20240152528
    Abstract: The present disclosure relates to utilizing a distributed data management system to provide improved data management, redundancy, and reliability in distributed directory systems. To illustrate, a distributed data management system improves existing distributed directory systems by relocating and distributing the management of data records from a centralized cache device to the backend storage partition devices. In this manner, the backend storage partition devices become responsible for automatically pushing data record metadata and changes to the centralized cache device, which only passively redirects the incoming requests to the proper backend storage partition devices. Additionally, the backend storage partition devices automatically resolve conflicts and restore lost data if the centralized cache device or a backend storage partition device suffers from faults or device failures.

  • Patent number: 11353524
    Abstract: A system for measuring magnetic field gradients comprising a multi-bay support structure with a series of raised contact shoulders separated from each other by voids. An optical fiber is spaced along the length of the multi-cell support structure and traverses all the raised contact points and voids. The optical fiber has a plurality of Fiber Bragg gratings (FBGs) spaced lengthwise, each FBG suspended in a void. In addition, a plurality of ferromagnetic members are strung onto the optical fiber, each suspended in a void. Magnetic field gradients act on the ferromagnetic member to create localized tension in the optical fiber. The FBG's refractive indices are monitored, tension is calculated therefrom, and the tension is correlated to the magnetic field gradient. This greatly simplifies mechanical, optical, electronic and computational complexity and is bay suited for any FOSS array for measuring magnetic fields using many dense measurement points.

  • Patent number: 10612911
    Abstract: A method and system for rendering the quaternion shape and orientation of a three-dimensional structure. The proposed system and method keeps track of twist/roll angles and updates its effect on pitch and yaw orientations. The system relies on a single or multi-core optical fiber or multi-fiber bundle containing fiber Bragg grating sensors (FBGs) arrayed in rosettes at 45° deltas and spaced at uniform intervals along the entire length of the structure to be monitored. A tunable laser is used to interrogate the sensors using optical frequency domain reflectometry (OFDR), which detects shifts in the wavelength reflected by the sensors in response to strain on the fibers. Each sensor is continuously queried by software which determines the strain magnitude (?L/L) for each fiber at a given triplet. Given these measured strain values, the software implements a novel quaternion approach to rendering the 3D shape of the fiber including twist.
