  • Publication number: 20220299552
    Abstract: According to one implementation, an aviation system 100 includes electric field sensors 112 and a ground system 114 including a computer configured to communicate with each of the electric field sensors 112. The computer is configured to: acquire electric field intensities from the electric field sensors 112 respectively, and generate a first electric field distribution on a ground surface 16 based on the electric field intensities; derive a matrix; derive a pseudo inverse matrix of the matrix; derive an electric charge distribution on the horizontal plane by multiplying the pseudo inverse matrix by the first electric field distribution on the ground surface 16; and derive a second electric field distribution on a flight path based on the electric charge distribution. The first electric field distribution on the ground surface 16 is derived by multiplying the matrix by electric charges temporarily set on a horizontal plane at a predetermined altitude.

  • Patent number: 7882937
    Abstract: An elevating machine control apparatus controls an inverter (4) to drive an AC motor (5) connected to the inverter (4) with AC power, and energizes a power generation braking resistor (13) to apply a brake during regenerative operation of the AC motor (5). The apparatus prohibits the elevating machine from starting operating and interrupts power supply to the power generation braking resistor (13) if the DC stage voltage of the inverter (4) has a ripple quantity of a set value or more when the elevating machine is being stopped. Alternatively, the apparatus commands the elevating machine to stop operating and interrupts power supply to the power generation braking resistor (13) if the DC stage voltage of the inverter (4) during regenerative operation is a reference value or less when the elevating machine is in operation.
