  • Patent number: 10727041
    Abstract: The invention generally relates to systems and methods for separating ions at about or above atmospheric pressure. In certain embodiments, the invention provides systems that include an ionization source that generates ions and an ion trap. The ion trap is maintained at about or above atmospheric pressure and includes a plurality of electrodes and at least one inlet configured to receive a gas flow and at least one outlet. The system is configured such that a combination of a gas flow and one or more electric fields produced by the electrodes separates the ions based on mass-to-charge ratio and sends the separated ions through the at least one outlet of the ion trap.

  • Publication number: 20200219711
    Abstract: The invention generally relates to apparatuses for focusing ions at or above ambient pressure and methods of use thereof. In certain embodiments, the invention provides an apparatus for focusing ions that includes an electrode having a cavity, at least one inlet within the electrode configured to operatively couple with an ionization source, such that discharge generated by the ionization source is injected into the cavity of the electrode, and an outlet. The cavity in the electrode is shaped such that upon application of voltage to the electrode, ions within the cavity are focused and directed to the outlet, which is positioned such that a proximal end of the outlet receives the focused ions and a distal end of the outlet is open to ambient pressure.

  • Patent number: 10419108
    Abstract: An optics module sends, to a host module, a pin signal indicating that an optics module is plugged into the host module, wherein the optics module is configured to operate at at least a first data rate and a second data rate. The optics module receives, from the host module, an indication of a host data rate. The optics module determines whether there is clock and data recovery loss of lock between the first data rate and a host data rate. If it is determined that there is clock and data recovery loss of lock between the first data rate and the host data rate, the optics module initializes at the second data rate if the second data rate matches the host data rate.

  • Patent number: 10295629
    Abstract: The present embodiments provide a gradient coil assembly. The gradient coil assembly includes an aluminum wire body, and a copper wire end connected by cold pressure welding to two ends of the aluminum wire body. Using the gradient coil according to a particular embodiment, it is possible to reduce gradient coil weight as well as reduce the thickness of an outer vacuum chamber used for a magnet, thereby reducing the cost of the magnet and gradient coil, and making it less difficult to install and maintain the magnet and gradient coil. There is no problem of oxidation associated with the cold pressure welding of the aluminum wire body to the copper wire ends, so quality defects arising from such oxidation are avoided.

  • Patent number: 10228431
    Abstract: A gradient coil for a magnetic resonance imaging system has a primary coil set in a cylindrical shape, a secondary coil set cylindrically sheathed on an outer periphery of the primary coil set, and one or more support structures located on the outer periphery of the primary coil set to support the secondary coil set in a radial direction of the gradient coil. This gradient coil can reduce the costs of filling material, reduce the time for assembling the gradient coil, and reduce the risk of breaking the gradient coil during demolding from a shimming mold.
