An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, a line having one end coupled to the chassis and an opposite free end, wherein the free end is positioned below the chassis, and a severing mechanism operable to sever the line under control of the control system.

An aeronautical vehicle that rights itself from an inverted state to an upright state has a self-righting frame assembly has a protrusion extending upwardly from a central vertical axis. The protrusion provides an initial instability to begin a self-righting process when the aeronautical vehicle is inverted on a surface. A propulsion system, such as rotor driven by a motor can be mounted in a central void of the self-righting frame assembly and oriented to provide a lifting force. A power supply is mounted in the central void of the self-righting frame assembly and operationally connected to the at least one rotor for rotatably powering the rotor. An electronics assembly is also mounted in the central void of the self-righting frame for receiving remote control commands and is communicatively interconnected to the power supply for remotely controlling the aeronautical vehicle to take off, to fly, and to land on a surface.

An aerial utility meter read system and a custom utility meter read equipment carrying case are disclosed. The custom utility meter read equipment carrying case is configured to attach to a drone while securely carrying operable wireless radio-based utility meter read equipment used to conduct aerial utility meter reads.

Provided is a discharge apparatus for an air vehicle, capable of reducing a loss of discharge pressure from an aerosol container. The discharge apparatus for an air vehicle discharges contents from an aerosol container 10 mounted on an airframe 101 through a nozzle 15. The aerosol container 10 is mounted on an exterior of the airframe 101, and one end of the nozzle 15 is supported by a discharge end part of the aerosol container 10 via a pipe joint 17 that allows the nozzle 15 to rotate so as to be rotatable around at least one rotation axis M.
