The present disclosure relates systems and methods involving movable/adjustable guardrails. An example system includes a frame weldment and a rail assembly attached to the frame weldment. The rail assembly includes a first post and a second post. The base portion of the first post is rotatably coupled to a first pivot point of the frame weldment and the base portion of the second post is rotatably coupled to a second pivot point of the frame weldment. The system also includes a top rail rotatably coupled between a top portion of the first post and a top portion of the second post. The system yet further includes an actuator configured to controllably adjust a configuration of the rail assembly between an extended configuration and a retracted configuration with respect to the frame weldment.

A landing station for an unmanned aerial vehicle includes a landing surface and a centering wheel. The centering wheel is coupled to the landing surface and has a spoke extending therefrom. The spoke is positioned to rotate relative to the landing surface in response to rotation of the centering wheel relative to the landing surface. The spoke is configured to rotate into engagement with a landing leg of the unmanned aerial vehicle to impart centrifugal force onto the landing leg sufficient to rotate the unmanned aerial vehicle toward a predetermined position on the landing surface.

A drone docking system (10) for multicopter drone (50) comprises a docking station (20) having a receiver (26). The CT receiver (26) is adapted to connect to a docking formation (52) mounted atop the drone (50) such that when the drone (50) is docked with the docking station (20), the drone (50) is suspended from and below the docking station (20). A fail-safe mechanical connection (56, 32) is provided to connect the docking formation (52) to the receiver (26). One or more electromagnets (34, 58) may be used to NI connect the docking formation (52) to the receiver (26), which electromagnets (34, 58) are suitably controllable to provide a smooth transition between docked and free-flight states of the drone (50) and optionally to guide the docking formation (52) into alignment with the receiver (26). The drone (50) suitably has a payload rendering it useful for surveillance and crime prevention/detection purposes.

Improved systems, apparatus, and methods for enhanced positioning of an airborne relocatable communication hub supporting wireless devices are described. Such a method begins with moving an aerial communication drone operating as the airborne relocatable communication hub to a first deployed airborne position, detecting a first signal broadcast by a first wireless device using a communication hub interface on the drone, and detecting a second signal broadcast by a second wireless device using the communication hub interface. The method has the drone comparing a first connection signal strength for the first signal and a second connection signal strength for the second signal, and repositioning the aerial communication drone to a second deployed airborne position based upon the comparison. Once repositioned at the second deployed airborne position, the method has the drone linking the first and second wireless devices using the communication hub interface on the aerial communication drone.

A storage unit for an Unmanned Aerial Vehicle (UAV) includes a container, a UAV landing platform, and a receptacle. The container is provided for enclosing the UAV. The receptacle is positioned above the UAV landing platform and it includes at least one inclined surface for guiding a landing UAV to a predetermined UAV landing position on the UAV landing platform.

A method of protecting against impact between a vehicle and a physical structure of a facility having an opening for the vehicle to pass through includes defining a monitored plane relative to an edge of the opening, the monitored plane defined by a plurality of baseline measurements, wherein each of the plurality of baseline measurements: 1) corresponds to a distance between a sensor spaced apart from the edge and one of a plurality of virtual ends of the monitored plane, and 2) is identified by an angle parameter. The method also includes obtaining a subsequent measurement; evaluating the subsequent measurement relative to a corresponding baseline measurement to determine if a criterion indicative of an intrusion of the monitored plane is satisfied; and activating an alarm when the criterion is satisfied.

Systems, apparatuses, and methods for autonomously estimating the position and orientation (“pose”) of an aircraft relative to a target site are disclosed herein, including a system including a plurality of beacons arranged about the target site, wherein the plurality of beacons collectively comprise at least one electromagnetic radiation source and at least one beacon ranging radio, a sensor system coupled to the aircraft including an electromagnetic radiation sensor and a ranging radio configured to determine a range of the aircraft relative to the target site, and a processor configured to determine an estimated pose of the aircraft based on at least: (i) detected electromagnetic radiation, and (ii) time-stamped range data for the aircraft relative to the target site.

Drone-based systems and methods are described for providing an airborne relocatable communication hub within a delivery vehicle for broadcast-enabled devices maintained within the delivery vehicle. Such a method has an aerial communication drone paired with the delivery vehicle transitioning to an active power state, uncoupling from a secured position on an internal docking station fixed within the delivery vehicle and then moving to a first deployed airborne position within the delivery vehicle. At a first position, the method has the aerial communication drone establishing a first wireless data communication path to a first broadcast-enabled device within the delivery vehicle, then establishing a second wireless data communication path to a second broadcast-enabled device within the delivery vehicle. The drone then couples the first and second wireless data communication paths it established operating as the airborne relocatable communication hub for the devices.

Method and system to ascertain location of drone box for landing and charging drones comprising at least a drone box having a drone platform with a plurality of limiting boundaries, divided into number of sensor zones that are mechanically contiguous and electrically separated by an insulated separator of insulation width, each sensor zone having an identification coordinates, each drone having a plurality of ground interfaces, each having a unique address code, each ground interface has a charging terminal at a far end, each charging terminal having an interlocked switchable electricity polarity. The identification coordinates of the activated sensor zones are communicable to a second drone so that the second drone knows where NOT to land on the drone box, Such communication enables a third and subsequent drone to ascertain whether the identified drone box is suitable and available for landing.
