  • Patent number: 9937808
    Abstract: A charging system for drones has a base structure connected to a power grid, a connector extendable from the base structure and ending in a charging interface compatible with a charging port of a drone, and a computerized controller at the base structure enabled to communicate with a drone and to initiate, control and stop charging power. As a drone approaches the charging-system, the controller directs the drone into position for charging, manages connection of the charging interface to the charging port of the drone, initiates charging power, monitors progress of charging, and upon completion of charging, disconnects the charging interface from the charging port of the drone.

  • Patent number: 9909602
    Abstract: A surface plasma actuator includes a conducting wire attached to a surface of a target object and electrically insulated from the target object. Surface plasma is generated along a neighborhood of the conducting wire by applying a pulse voltage between the conducting wire and a conductive portion on a side of the target object. An induced gas flow is generated by the surface plasma.

  • Patent number: 9889756
    Abstract: A drive over estimating unit of an electric vehicle estimates whether or not wheels of the vehicle will drive over a power supplying coil, e.g., power supplying pad, from a stopped position estimation value, e.g., a deviation amount in a direction of positional shifting of the electric vehicle with respect to the power supplying pad, and a steering angle (?? (left) or +? (right)) when the vehicle starts to move after non-contact charging thereof is completed. A notification unit issues a notification when it is estimated that the wheels of the electric vehicle will drive over the power supplying coil, e.g., power supplying pad.

  • Patent number: 9862338
    Abstract: A system for contactless energy transmission includes a transformer formed by a primary winding and a secondary winding, which transformer is designed so as to be resonant as a result of capacitors. By measuring and comparing electrical state variables on the primary side and on the secondary side the efficiency of the transmission of electrical power from the primary side to the secondary side is determined, and by varying the resonance frequency of the transformer or of the frequency of a primary voltage applied to the primary winding the resonance frequency and the primary voltage frequency are attuned to each other.
