  • WIRE ROUTING ALGORITHM
    Publication number: 20190340325
    Abstract: A method for determining a wire connection plan includes receiving a wiring specification including a set of links and a first set of connection points. Each link specifies a connection between two connection points of the first set of connection points. The method includes determining the wire connection plan including an ordered sequence of wire segments linking points of a second set of connection points, the second set of connection points including the first set of connection points and a set of additional connection points.

  • Navigation systems and methods using fiber optic shape sensors and localized position sensors
    Patent number: 10317196
    Abstract: Systems and methods for determining the shape and/or position of an object are described. A fiber optic shape sensor (FOSS) may be used in combination with one or more inertial measurement units (IMUs) to mutually cross-correct for errors in the sensors' measurements of position and/or orientation. The IMU(s) may be attached to the FOSS's optical fiber, such that each IMU measures the orientation of a corresponding portion of the optical fiber. The position and shape of the optical fiber can then be determined based on the measurements obtained from the IMU(s) and the measurements obtained from the FOSS. For example, the FOSS measurements and the IMU measurements can be provided to a state estimation unit (e.g., a Kalman filter), which can estimate the position and/or shape of the optical fiber based on those measurements. In some embodiments, the estimates of position are used for navigation of tethered mobile devices.
