  • Publication number: 20220151054
    Abstract: A method and system for stably generating and accelerating magnetized plasma comprises ionizing an injected gas in plasma generator and generating a formation magnetic field to form a magnetized plasma with a closed poloidal field, generating a reverse poloidal field behind the magnetized plasma and having a same field direction as a back edge of the closed poloidal field and having an opposite field direction of the formation magnetic field, and generating a pushing toroidal field that pushes the reverse poloidal field against the closed poloidal field, thereby accelerating the magnetized plasma through a plasma accelerator downstream from the plasma generator. The reverse poloidal field serves to prevent the reconnection of the formation magnetic field and closed poloidal field after the magnetized plasma is formed, which would allow the pushing toroidal field to mix with the closed poloidal field and cause instability and reduced plasma confinement.

  • Publication number: 20220120828
    Abstract: A magnetic sensor device with an array of magnetic sensors arranged on a common semiconductor substrate to measure the multi-axis magnetic field of an arbitrary region with high spatial resolution, reduced sensing distance, higher measurement throughput, motion tolerance, temperature tolerance, and improved manufacturing yield. A multi-axis magnetic sensor array device fabricated on a common semiconductor substrate is optimized offering additional improvements to reduce measurement time, increase spatial resolution uniformity, and lower thermal compensation cost. Further, the central area of a surface is utilized to measure the normal magnetic field. A perimeter of Hall effect plates measuring the components of the magnetic field in the plane of the measuring surface, which allows for a very high density of normal field measurements allows calculation of the in-plane field components. Error along the edges can be mitigated with the in-plane measured components.

  • Publication number: 20220114264
    Abstract: A method for determining authenticity of a component in an imaging device is disclosed. Embodiments of the present disclosure provide for a method for a device to use an electronic authentication scheme to authenticate a second device while overcoming vulnerabilities associated with sending data over a communication bus when performing authentication, by using information other than that transmitted over the shared bus as authentication parameters. Embodiments utilize the current drawn by a chip from a power source when the chip performs an operation in response to a command as an authentication parameter.

  • Publication number: 20210217536
    Abstract: A system for generating magnetized plasma and sustaining plasma's magnetic field comprises a plasma generator for generating magnetized plasma and a flux conserver in which the generated magnetized plasma is injected and confined. A central conductor comprises an upper central conductor and a lower central conductor that are electrically connected forming a single integrated conductor. The upper central conductor and an outer electrode form an annular plasma propagating channel. The lower central conductor extends out of the plasma generator and into the flux conserver such that an end of the inner electrode is electrically connected to a wall of the flux conserver. A power system provides a formation current pulse and a sustainment current pulse to the central conductor to form the magnetized plasma, inject such plasma into the flux conserver and sustain plasma's magnetic field.
