A remotely controlled unmanned aerial device for use in proximity or in contact with high voltage powerlines, includes an unmanned aerial vehicle and an electrically conductive shield forming part of or operatively coupled to so as to encapsulate the unmanned aerial vehicle. When in the presence of a high voltage powerline, the unmanned aerial vehicle either when bonded-on or within the corresponding magnetic fields of the powerline, so as to transfer the powerline potential in whole or in part to the unmanned aerial vehicle, electrically energizes the conductive shield around the unmanned aerial vehicle while leaving components of the unmanned aerial vehicle within the shield substantially electrically unaffected by the voltage potential.

Provided are an information management method, an identification information imparting apparatus, and an information management system that use a spray pattern capable of identifying a target object in a simple way. The present invention is characterized by: spraying a liquid material on a part of a target object (Oi) by the liquid material ejection device (10) to form an irregular spray pattern (Mi); storing a spray pattern image (Pi), which is obtained by photographing and imaging the spray pattern (Mi), and information (Ri) about the target object in association with each other; and managing the information about the target object using the spray pattern image (Pi) as identification information of the target object.

Unmanned vehicles can be terrestrial, aerial, nautical, or multi-mode. Unmanned vehicles may be used to survey a property in response to or in anticipation of a threat. For example, an unmanned vehicle may analyze information about the property and based on the information deter theft of items on the property.

The present invention discloses a drone or unmanned aerial vehicle (UAV) mounted on a law enforcement vehicle for the purposes of interfacing with occupants of a stopped vehicle after being pulled over for a traffic violation or routine stop. The drone is equipped with a navigation system, obstacle-avoidance sensors, a telepresence system (a camera, microphone, speaker and screen), and a robotic arm with a secure box and a device for estimating blood alcohol content. Once a suspect vehicle has been pulled over by a law enforcement officer, without leaving the safety of a law enforcement vehicle, the officer deploys the drone to perform a visual check of the interior of the suspect vehicle for dangerous items, ascertain if an occupant's face triggers any flags on a central database, administer a sobriety test, collect the necessary documents and deliver a citation to the driver via the secure box.

In some implementations, a UAV flight system can dynamically adjust UAV flight operations based on radio frequency (RF) signal data. For example, the flight system can determine an initial flight plan for inspecting a RF transmitter and configure a UAV to perform an aerial inspection of the RF transmitter. Once airborne, the UAV can collect RF signal data and the flight system can automatically adjust the flight plan to avoid RF signal interference and/or damage to the UAV based on the collected RF signal data. In some implementations, the UAV can collect RF signal data and generate a three-dimensional received signal strength map that describes the received signal strength at various locations within a volumetric area around the RF transmitter. In some implementations, the UAV can collect RF signal data and determine whether a RF signal transmitter is properly aligned.

A dimming device for a switchable glass includes a third wireless communications component and a third controller. The third wireless communications component is configured to establish a communications connection to a master computer and a second unmanned aerial vehicle, and to receive a target transmittance sent by the master computer and a transmittance of a switchable glass to be detected sent by the second unmanned aerial vehicle. The third controller is configured to adjust a voltage applied to the switchable glass to be detected when the transmittance of the switchable glass to be detected is inconsistent with the target transmittance, so that the transmittance of the switchable glass to be detected is consistent with the target transmittance.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for reserving airspace for UAV operations. In some implementations, a flight planning system can reserve and allocate airspace for unmanned aerial vehicle (UAV) operations. For example, a UAV operator device can submit a flight plan to the flight planning system. The flight planning system can submit a flight authorization request to an airspace management system to reserve airspace necessary for the flight plan. The flight planning system can receive approval and/or a reservation of the airspace for the flight plan from the airspace management system, generate a flight data package, and send the flight data package to the operator's device.

A tool positioning system of an unmanned aerial vehicle that is mountable relative to a power line to monitor a component of the line. The tool positioning system includes a displacement module having a first member mountable to one side of a body of the unmanned aerial vehicle, a second member movable vertically relative to the first member on the side of the body, and a tool holder pivotably coupled to the second member and couplable to a tool. The tool holder is movable relative to the body to mount the tool to or around the component.

An inspection operator can perform a hammering inspection without operation to move an inspection device to a location to be inspected, and the hammering inspection can also be performed to the location to be inspected where a vehicle has difficulty in entering. An inspection system includes a flying device including a hammering inspection unit that performs an inspection and a flying unit that flies with the hammering inspection unit, a ground-side device that is fixedly installed at a position relative to a location to be inspected and detects a position of the flying device, and a flight instruction unit that controls the flying device in such a way that a forwarding direction of the flying device is a direction from the ground-side device to the location to be inspected based on the position of the flying device.
