    摘要: An aircraft seat arrangement having identical groupings, each separately including at least one aircraft seat, each including a voltage supply port associated only with the aircraft seat for the connection of external devices of a passenger seated on the aircraft seat, a voltage supply unit, with a voltage input, at least one voltage output, each connected to the voltage supply port of another of the aircraft seat, and a switching circuit, such that each of the voltage output can be activated and deactivated. At least one control unit is connected to the switching circuit, and a near-field communication reading device is connected to the control unit for wireless reception of near-field communication signals from an external near-field communication sending device. The communication reading device can receive signals from a predetermined group of predetermined near-field communication signals. The number of predetermined signals in the group equals the number of aircraft seats in the grouping and each of the predetermined near-field communication signals is associated with another of the aircraft seats of the grouping. The control unit activates the voltage supply port by the switching circuit only upon receiving one of the predetermined signals, which port is associated with the aircraft seat associated with the received predetermined near-field communication signal.

    摘要: Methods and systems for detecting and passively monitoring communication of an unmanned aerial vehicle are disclosed. In an example method, a radio frequency spectrum is scanned to detect one or more radio signals transmitted within a pre-defined area. A modulated radio signal of interest from the one or more radio signals is determined. The radio signal of interest is associated with a drone. The radio signal of interest is captured. The radio signal of interest is demodulated to determine coded sensor data carried by the radio signal of interest. The sensor data is determined by the drone. The coded sensor data is decoded to determine a characteristic of the sensor data. An alert is generated based on the characteristic of the sensor data.

    摘要: A system for transmitting signals includes Orbital Angular Momentum (OAM) processing circuitry for receiving a plurality of input signals and applying a different orbital angular momentum to each of the plurality of input signals for transmission to a second location. Electromagnetic knot processing circuitry receives a plurality of OAM processed signals from the OAM processing circuitry and applies an electromagnetic knot to each of the received OAM processed signal before transmission to the second location. Multiplexing circuitry multiplexes the plurality of OAM/electromagnetic knot processed signals into a single multiplexed OAM/electromagnetic knot processed signal. A first signal degradation caused by environmental factors of the OAM/electromagnetic knot processed signal is improved over a second signal degradation caused by the environmental factors of a signal not including the electromagnetic knot. A transmitter transmits the single multiplexed OAM/electromagnetic knot processed signal to the second location.
