  • Publication number: 20190191472
    Abstract: An electronic device includes at least one wireless communication circuit positioned, and at least one processor operatively connected to the wireless communication circuit. The wireless communication circuit includes an omni-directional first wireless communication circuit capable of communicating at first frequency within a first coverage and a directional second wireless communication circuit capable of communicating at a second frequency higher than the first frequency, within a second coverage smaller than the first coverage. The processor is configured to obtain control information including data regarding a location of an external device, from the external device through the first wireless communication circuit, to set a beamforming attribute associated with the second wireless communication circuit, based on the data, and to establish a communication connection to the external device through the second wireless communication circuit, by using the beamforming attribute.

  • Publication number: 20130068877
    Abstract: An existing bottom-adjustable propeller-type flying object requires a device having a complex structure constructed through the combination of various components such as a servo, a control plate, and a hinge to control the rotor pitch at every moment and operate an adjustable blade for flight control. The bottom-adjustable propeller-type flying object of the disclosure includes a circular frame with a fixing plate and a protective plate installed at a lower portion of a shaft of a power propeller mounted to the central shaft, and an adjusting motor having an adjustable propeller. The flying object moves up or down by using force of the wind generated downward due to the rotation of the power propeller. The flying object makes a hovering flight, and leftward, rightward, forward, and backward flights by using the force of the wind generated due to the rotation of the adjustable propellers mounted on two adjusting motors.

  • Patent number: 8272593
    Abstract: Conventional bottom blade type flight vehicles have a complex structure and complex flying control operations in that several pairs of fixing plates, and forward/backward and left and right rotation adjustment blades are separately mounted and adjusted to remove the anti-torque of the flight vehicle caused by the rotation of the propellers and to fly the flight vehicle, so that the flight vehicles has difficulties in scouting and surveillance of an indoor area due to the heavy weight and the great volume. The flight vehicle of the disclosure continuously rotates in a state in which the anti-torque is not removed by one adjustment blade. The flight vehicle stops, ascends, descends, advances forward, backward, leftward, or rightward, or left or right rotates, performs flight in a narrow space, scouting and surveillance in an indoor area with a simple structure, simple control, light weight, and small size, and increases power efficiency.

  • Patent number: 8251308
    Abstract: Conventional bottom blade type trefoil flight vehicles have composite structures wherein a plurality of pairs of fixing plates, forward/backward adjustment blades, and left and right rotation adjustment blades are separately mounted and adjusted, and thus have difficulties in scouting and surveillance in an indoor area due to the heavy weights and the large volumes of the flight vehicles. Another conventional flight vehicle has drawbacks in that flight in the left and right directions is difficult, and an adjustment blade and a fixing plate are arranged adjacent to each other to cause mutual influences of wind and non-uniformity in the flow of wind. The present invention provides a flight vehicle characterized in that three pairs of fixing plates with fixed pitch propellers and adjustment blades are installed at an angle of 120 degrees.
