  • Patent number: 11961648
    Abstract: A rapid demagnetization method based on characteristics of magnetic media. In the method, basic information is obtained by a recognition module of magnetic media by means of multi-source sensing collaboration. The magnetic medium is identified by using a data processing technology and a magnetic medium identification algorithm, and then the characteristic information is extracted. Optimized set values of demagnetization parameters are obtained by a demagnetization parameter optimizing and setting module based on a demagnetization optimizing model. Demagnetization parameter set values are tracked by a closed-loop control module of a demagnetization magnetic field in combination with domain expert knowledge by using a closed-loop control mechanism integrated with a magnetic field control algorithm, a charging-discharging device, a magnetic field generating device, a magnetic field sensor and an environmental sensor, completing the rapid demagnetization of the magnetic medium.

  • Patent number: 11955277
    Abstract: Today, chemical rockets are the most expensive components of a launch; even reusable boosters require costly fuel, ongoing maintenance, and long durations between launches. As a result, far too many space bound opportunities are prohibitively expensive. However, kinetic launchers offer an economical alternative for projecting payloads into orbit. Harnessing angular velocity, a centrifuge gradually accelerates its payload to hypersonic speeds within a vacuum sealed chamber; upon reaching the desired speed, its airlock opens and the payload is released into the atmosphere. Flux-Pinned Superconductors offer a radical advancement to this technology; wherein, Flux Pinning is used to levitate and stabilize the launch package while reinforcing the entire platform against centrifugal stress. These Flux-Pinned joints require no power, lubricant or physical contact, while providing limitless stiffness that is essentially impervious to mechanical wear.

  • Patent number: 11948736
    Abstract: A superconducting magnet system having two-stage quenching. A primary coil assembly includes a coil section configured to be superconducting when conducting current below a first critical current. An EMI shielding coil assembly includes a coil section configured to be superconducting when conducting current below a second critical current, which is electrically coupled to a variable resistor configured to be superconducting when conducting current below a third critical current and to be non-superconducting when conducting current at or above the third critical current that is less than both the first and second critical currents. Generating a magnetic flux within the EMI shielding coil assembly causes the current conducted through the variable resistor to exceed the third critical current, quenching the variable resistor and generating heat. The EMI shielding coil assembly is disposed such that the heat from the variable resistor quenches the primary coil assembly.

  • Patent number: 11933423
    Abstract: A method for determining a switching point of a solenoid valve. A solenoid coil is energized to raise a solenoid armature to unblock a flow opening. For a signal profile characteristic of a current profile in the solenoid coil, multiple periods each different from one another and each having the same predefined temporal length are determined. Within each period, a minimal and a maximal value of the signal profile and associated points in time are ascertained and a product of a difference between the maximal and minimal value and a difference between the associated points in time are ascertained. On the basis of the points in time of the minimal and maximal value of that period, which corresponds to a maximal value of the product, the switching point is determined.
