  • Patent number: 10492741
    Abstract: For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. Additional examples are directed to applying selective filtering at a proximal end of the elongated member to provide a more stable base for distal measurements and thereby reducing the influence of measurement errors.

  • Publication number: 20190318434
    Abstract: Methods and systems for crop management are disclosed. An example method can comprise receiving first information associated with an environmental management zone. The first information can relate to one or more of a land characteristic and a management practice. The first information can comprise a soil type of the environmental management zone. An example method can comprise, receiving historical weather data relating to the environmental management zone. An example method can comprise receiving real-time weather data relating to the environmental management zone. An example method can comprise executing a growth model to predict a nitrogen range for the environmental management zone based on one or more of the first information, the historical weather data, and the real-time weather data. The nitrogen range can comprise probabilities for one or more of a current time period and a future time period in the growing season.

  • Patent number: 10130427
    Abstract: Systems and methods for introducing and driving flexible members in a patient's body are described herein. In one embodiment, a robotic method includes positioning a flexible elongated member that has a preformed configuration, wherein at least a part of the flexible elongated member has a first member disposed around it, and wherein the first member includes a first wire for bending the first member or for maintaining the first member in a bent configuration, releasing at least some tension in the first wire to relax the first member, and advancing the first member distally relative to the flexible elongated member while the first member is in a relaxed configuration.

  • Publication number: 20180326181
    Abstract: The present application is related to devices, systems, and methods for controlling active drive systems. In one embodiment, the drive system may include a first surface and a second surface for engaging an elongate member. The first and second surfaces may be attached to a drive mechanism to move the elongate member. The first surface may be slidable relative to the drive mechanism and may have a clearance between the drive mechanism and an end of the first surface during movement of the elongate member in a non-slip condition. A sensor may be associated with the first surface and may be configured to detect movement of the first surface in a slip condition.
