Abstract: An autonomous vehicle includes a chassis for housing an aircraft ground contacting structure (GCS) and one or more GCS coupling and lifting mechanisms, GCS securing mechanisms, drivetrain, batteries and a sensor stack for performing autonomous navigation. Further, the vehicle incorporates multiple sensors, such as high-resolution machine vision cameras, GPS modules, Lidars, ultrasonic range sensors, and radars. The sensors deliver spatial perception capabilities to the vehicle and feed relevant data to onboard computing units to achieve location-based navigation, precision alignment with aircraft, obstacle detection and collision avoidance capabilities. A series of batteries deliver power to all components, including but not limited to, motors, electromechanical units, onboard computers, sensors and any other component requiring electrical input. External ports allow the vehicle to recharge batteries after each utilization cycle without replacement.

Abstract: A rose pruning and stripping device includes first and second jaws pivotally connected between handle and cutting portions thereof. An inner edge of the cutting portion of the first jaw sharpened into a cutting edge, and the opposite inner edge of the cutting portion of the second jaw defines a dull edge. A multi-faceted notch is formed in each cutting portion of the first and second jaws between the pivotal connection and the sharpened edge. A leaf and thorn stripping aperture is formed as the handles of the first and second jaws, and particularly the cutting portions thereof, are brought towards one another.
