  • Segmented direct drive motor for use in a computed tomography system
    Patent number: 10143427
    Abstract: The present approach includes, in one implementation, a direct drive motor for use in a CT gantry and having a segmented motor stator assembly. The stator segments are connected in series. The stator segments are not independently operable and are instead connected in series to, and operated by, a single frequency controller.
    Type: Grant

  • System for optical communication between stationary and non-stationary parts and method of making same
    Patent number: 7848478
    Abstract: An optical communication system includes a rotatable base having a plurality of optical sources and optical receivers mounted thereon, and a stationary base having a plurality of optical sources and optical receivers mounted thereon. The system is configured to send and receive optical signals bi-directionally between the rotatable base and the stationary base while the rotatable base is rotating.
