Abstract: A method for balancing an aircraft turbofan engine using a respective artificial neural network for each flight of multiple reference aircraft to predict the engine vibrations that would be produced in response to input of flight parameter and balance weight data acquired from a flight of a test aircraft of the same type. The resulting sets of predicted vibrations are then processed to identify and collect those engine vibration predictions which match or nearly match the engine vibration measurements acquired from the test aircraft during its flight test. For each matching modeled flight of the reference aircraft, the magnitude and phase angle of the mass vector for any commonly used balance weight configurations are determined and included in a list of recommended balance weight configurations. A technician can then reconfigure the balance weights attached to the engine on the test aircraft in accordance with a selected recommendation.
Abstract: A method and system for continuously re-planning a vehicle's path, in the face of stationary and moving obstacles, dynamically calculates a new path in real time which is both efficient and maintains minimum safety clearances relative to obstacles. Repulsion signals emanating from obstacles and propagating through delineated sections of a grid representing a geographic space are summed along with values representing the relative distance of the sections from the vehicle origin and vehicle destination. The grid sections having optimal values according to a predetermined criteria represent an efficient and safe travel path between the vehicle origin and destination.
Abstract: A load handling system for a vehicle includes a set of forks that concurrently supports two or more pallets including a first pallet and a second pallet linearly positioned along a length of the forks, and a lifting system to raise and lower the forks. A traction system moves the vehicle in a direction of travel associated with withdrawing the forks from the pallets. Additionally, an actuation device generates an activation signal in response to being actuated by an operator, and a vehicle controller places the vehicle in an automated mode of operation in response to receiving the activation signal. In the automated mode of operation, a front end of the forks moves from the second pallet to the first pallet, and the first pallet is raised while the second pallet remains on a transport surface. The first pallet is then spaced apart from the second pallet by a predetermined distance and then lowered to the transport surface.
Abstract: A movement route generating apparatus includes an angle calculating unit calculating an angle formed by a vehicle travel direction at a target position compared with that at the current position, a graph generating unit generating a graph that has most gentle inclinations by plotting the curvature of a travel trajectory matching the steering angle of the vehicle and a distance traveled on two axes, under the condition that the area of a graph generated in correspondence to a travel trajectory from the current position to the target position is equal to the angle and other conditions, and a route setting unit setting a travel trajectory represented by the graph as the movement route of the vehicle. Accordingly, a travel trajectory with the smallest degree of change in curvature per unit distance traveled, that is, a low horizontal angular velocity caused by vehicle steering, can be set as a movement route.
Abstract: In an aerial vehicle, a malfunction determiner determines whether there is a malfunction in one of thrusters of the aerial vehicle. A flight controller activates the thrusters, and controls the output of each of the thrusters. The flight controller deactivates, when it is determined that there is a malfunction in one of the thrusters as a malfunctioned thruster, the malfunctioned thruster. The flight controller deactivates a selected thruster in the thrusters; the selected thruster being paired to the malfunctioned thruster, and controls the active thrusters except for the deactivated thrusters in all the thrusters to make the flight attitude of the aerial vehicle stable. The flight controller controls the active thrusters to cause the aerial vehicle to land while maintaining the flight attitude of the aerial vehicle being stable.

Abstract: A method comprising accessing sensor data from one or more autonomous escort vehicles in a convoy moving along a route, detecting based on the sensor data, an environmental vehicle along or in proximity to the route of the convoy, determining based on the sensor data and movement of the convoy, that the environmental vehicle should be prevented from interfering with the movement of the convoy, identifying a particular autonomous escort vehicle that is available to modify its position to prevent the environmental vehicle from interfering with the movement of the convoy, generating instructions for the autonomous escort vehicle to modify its position to prevent the environmental vehicle from interfering with the movement of the convoy along the route, and causing the instructions to be communicated to and executed by the autonomous escort vehicle to modify its position to prevent the environmental vehicle from interfering with the movement of the convoy.
Abstract: A parking assist system of a vehicle includes a plurality of sensors disposed at a vehicle and having respective fields of sensing exterior of the vehicle. A vehicle control is operable to determine a target parking space responsive to the processor. The control (i) uses two intersecting lines, with one passing through a start node and one passing through an end node, (ii) uses circles that are tangent to respective ones of the intersecting lines, with each circle having a radius that approximates a minimum turning radius of the vehicle, and (iii) determines possible paths of travel using straight path sections tangent to one or more of the circles and curved path sections that follow a curvature of one or more of the circles. The control selects a target path of travel in accordance with a plurality of objectives for the path of travel of the vehicle.
