The present invention provides a drone-passing multiple detection sensor gate comprising: a gate having a ring-like structure through which a drone can pass during flight; a first sensor, disposed on the front or the inner front of the gate, for detecting whether the drone approaches the gate or passes through the front side of the gate; a second sensor, disposed on the inner rear of the gate, for detecting whether the drone sensed by the first sensor passes through the rear side of the gate; a detection signal transmitter, disposed inside or on a surface of the gate, for receiving, from the first sensor and the second sensor, the detection signal indicating whether the drone approaches or passes through the gate, and wirelessly transmitting the detection signal. In addition, the present invention provides a drone game system using a multiple detection sensor gate.

A reconfigurable system capable of autonomously exchanging material from unmanned vehicles of various types and sizes. The system comprises an environmental enclosure, a landing area, a universal mechanical system to load and unload material from the unmanned vehicle, and a central processor that manages the aforementioned tasks. The landing area may comprise a one or more visible or non-visible markers/emitters capable of generating composite images to assist in landing the unmanned vehicle upon the reconfigurable, autonomous system.

Methods, devices, and systems for airfield luminaire vibration monitoring are described herein. In some examples, one or more embodiments include a computing device comprising a memory and a processor to execute instructions stored in the memory to receive a vibration signal from a sensor on an airfield luminaire, compare the vibration signal from the sensor to a vibration profile for the airfield luminaire, and determine a status of a bolt of the airfield luminaire based on the comparison.

A system for guiding a drone to an intended destination using a remote guidance system, independent of a global positioning system installed on the drone and independent of radio guidance. The system uses a two-way optical communication channel between the guidance system and the drone. The drone and the guidance system each have a light source emitting a beam of encoded light, such as a modulated laser beam, and having an extended field of illumination, and a detector receiving the impinging light beam. The guidance system can detect the angular location of the drone emission, and can transmit instructions optically to the drone, while the drone can receive flight path instructions from the guidance system. The drone can be launched from a position that is not in the line of sight of its intended destination and guided optically from the launch position to its intended target destination.
