  • Patent number: 11254551
    Abstract: An apparatus for controlling tension in a pulling rope that is attached to a flying, unmanned aerial device or drone may utilize a cylinder around which the rope is wound, a shaft that longitudinally passes through the cylinder, a disc brake rotor that is mounted to the shaft, a brake caliper that is mounted circumferentially at a periphery of the disc brake rotor, and a brake lever that tensions a cable that is attached to, and movable to control movement of, the brake caliper, which may be hydraulic, against surfaces the disc brake rotor. The brake lever may be hand actuated and mounted to a handlebar. A frame may be part of the apparatus and support apparatus components and may have a protruding hitch portion that inserts into a vehicle's receiver hitch. An adjustable pulling rope guide support through which the rope is threaded, mounts to the frame.

  • Patent number: 10145920
    Abstract: Magnetic resonance imaging (MRI) systems and methods for determining and adjusting TI using single-line acquisition and automatic compartment detection. A method includes positioning a readout line of the MRI scanner through a compartment of interest of a region of interest in a subject. The method includes inverting magnetization within the readout line by playing an inversion pulse; and reading out data along the readout line after play of the inversion pulse. The method also includes determining a T1 value for each pixel along the readout line; determining the pixels that belong to first and second portions within the compartment of interest; determining a T1 value of each of the first and second portions by averaging the pixels within each portion; and determining an inversion time based on the determined T1 values such that the compartment of interest has a desired magnetization in an image to be acquired.
