In the present invention, various examples are possible.

Example vehicle inspection systems and methods are described. In one implementation, a method activates an unmanned aircraft inside a vehicle to capture images of the vehicle interior. The method accesses a flight path for the unmanned aircraft and receives data associated with the vehicle's current movement. The method adjusts the flight path of the unmanned aircraft to compensate for the vehicle's current movement.

This data processing device is provided with: an acceleration acquisition unit that acquires the acceleration of a moving body equipped with a mechanism for generating a propulsion force and equipped with a measuring instrument for measuring the strength of at least a one-direction component of the wind to which the moving body is exposed; a wind information acquisition unit that acquires wind information indicating the blowing direction of the wind and the strength of the wind, both of which are identified from the values measured by the measuring instrument; an external force estimation unit that estimates, on the basis of the acceleration and the direction and magnitude of the propulsion force, the magnitude of an external force exerted by the wind on the moving body; and a generation unit that generates relational information indicating the relation between the wind strength and the estimated magnitude of the external force.

An industrial activity drone comprising an aerial vehicle having at least one rotor, an activity system, and a fastener device for fastening the activity system to the aerial vehicle. The activity system includes a structure, a computer, a work camera that is stationary relative to the aerial vehicle and that provides a view of a work zone, a distribution device having a plurality of compartments, and a turning motor enabling the distribution device to turn relative to the aerial vehicle. The industrial activity drone performs hovering flight so that the work camera faces a work zone and the distribution device is turned so that the compartment that is to be used faces the work zone, thereby performing one or more tasks.

An apparatus and method for refueling an aircraft comprising a hose guide. The hose guide includes a framework having wings and remotely-adjustable control surfaces interacting with air through which the hose guide moves. An attachment interface, attaching the hose guide to a fuel hose extended from a tanker aircraft, at a distal end away from the tanker aircraft, and a control system adjusting the adjustable control surfaces. Wherein the hose guide is towed as a glider by the tanker aircraft, and adjustment of the control surfaces adjusts three-dimensional position of the end of the fuel hose at the hose guide relative to position of the tanker aircraft.

A ferromagnetic actuator is disposed between first and second semiconductor devices that include first and second inductors. Each inductor is disposed on top of a multilevel wiring structure. Current flows through the first inductor to generate a first magnetic field that attracts the ferromagnetic actuator towards the first inductor causing the ferromagnetic actuator to transition from a first state to a second state. In the second state, a portion of the ferromagnetic actuator is disposed closer to the first inductor than it is in the first state. Current flows through the second inductor to generate a second magnetic field that attracts the ferromagnetic actuator towards the second inductor causing the ferromagnetic actuator to transition from the first or second state to a third state. In the third state, a portion of the ferromagnetic actuator is disposed closer to the first inductor than it is in the first state.

A drone apparatus or arrangement is provided. The drone apparatus or arrangement includes a plurality of drone devices, each drone device including an unmanned vehicle configured to be controlled to hover in air at a desired height and move to a desired location, each drone device comprising a rechargeable battery connected to an exposed drone recharging surface, and a surface apparatus connected to the plurality of drone devices such that the plurality of drone devices are collectively controllable to reposition the surface apparatus to a desired location. Each drone device is configured to connect to and recharge at a compatible charging station including an exposed recharging station recharging surface configured to meet with one exposed drone recharging surface to recharge the rechargeable battery.

A motorized device capable of moving in a fluid and including one or more locomotor systems, each having at least one drive assembly linked to at least one locomotion member and a motor controlled by a voltage. The frequency of a reciprocating motion of the drive assembly matches the resonant frequency of the locomotion member linked to a non-movable portion by at least one prestrained elastic member. The instantaneous amplitude of the reciprocating motion of the drive assembly is adjusted to control the average position and the maximum amplitude of the reciprocating motion of the locomotion member. The drive assembly includes at least one speed reducer for reducing the speed of rotation of the motor. When the motor is operating at its maximum mechanical power, the speed of rotation transmitted to the at least one locomotion member is reduced to match the resonance frequency.

The present technology is directed to a remotely controlled aircraft that can be transported without the risk of damaging certain components, such as the arms and/or propellers. In one non-limiting example, the remotely controlled aircraft technology described herein provides a housing that allows the arms of the remotely controlled aircraft to extend and/or retract through openings in the housing. When retracted, the arms and propellers are protected within an area of the structure of the housing, and when extended, the arms and propellers are operable to make the remotely controlled aircraft fly.
