Abstract:
A method for transporting maintenance personnel at a cell tower includes, responsive to a requirement for a tower climb for one or more of a site survey, a site audit, maintenance, and installation at the cell tower, securing a person in a drone, wherein the drone includes flight components at a substantial length from the person allowing the flight components to fly over a top of the cell tower and to place the person directly adjacent to a desired location on the cell tower; flying the drone up the cell tower to locate the person directly adjacent to the desired location; and performing the one or more of a site survey, a site audit, maintenance, and installation at the cell tower.
Abstract:
A modeling method performed for a cell site to detect changes in or at the cell site includes obtaining first data regarding the cell site from a first audit performed using one or more data acquisition techniques and obtaining second data regarding the cell site from a second audit performed using the one or more data acquisition techniques, wherein the second audit is performed at a different time than the first audit; processing the first data to define a first model of the cell site using the associated one or more location identifiers and processing the second data to define a second model of the cell site using the associated one or more location identifiers; comparing the first model with the second model to identify the changes in or at the cell site; and performing one or more actions based on the identified changes.
Abstract:
A tethered flight control system for a small unmanned aircraft. The tethered flight control system can have a mobile base, a tether arm, a tether spout, and a remote-controlled winch that can hold a tether line, which can be connected to a small unmanned aircraft. By controlling the tether line using the winch, the small unmanned aircraft can be prevented from flying out of range or out of control. The winch can have a high-speed motor configured to remove substantially all slack from the tether line while the small unmanned aircraft is in flight. The winch can be controlled from a hard-wired winch remote, which can take the form of a foot pedal device having one or more foot pedals. The tether line can be attached to the small unmanned aircraft through a tether attachment apparatus, which can have a travel bar, two or more rotor protectors, and a mounting section.
Abstract:
A tethered unmanned aerial vehicle (“UAV”) may be outfitted with a sensor payload for data gathering. The tethered UAV may be tethered to a ground station for constricting the flight space of the UAV while also providing the option for power delivery and/or bidirectional communications. The tethered UAV's flight path may be extended by introducing one or more secondary UAVs that cooperate to extend the horizontal flight path of a primary UAV. The ground station, which may be coupled with the tethered aerial vehicle, may comprise a listening switch configured to determine a condition of the tether such that the supply of power to the tether may be terminated when tether damage or a tether severance is detected.
Abstract:
A method may involve operating an aerial vehicle in a hover-flight orientation. The aerial vehicle may be connected to a tether that defines a tether sphere having a radius based on a length of the tether, and the tether may be connected to a ground station. The method may involve positioning the aerial vehicle at a first location that is substantially on the tether sphere. The method may involve transitioning the aerial vehicle from the hover-flight orientation to a forward-flight orientation, such that the aerial vehicle moves from the tether sphere. And the method may involve operating the aerial vehicle in the forward-flight orientation to ascend at an angle of ascent to a second location that is substantially on the tether sphere. The first and second locations may be substantially downwind of the ground station.

A system is disclosed including an aerial vehicle to perform a task to an object, while in an aerial mode that includes at least one of a hover mode or a slow movement mode during a predominant phase of the task being performed, the aerial vehicle has a command and control system, a removable mobile computing device that when attached to the aerial vehicle assists in control of the aerial vehicle and when detached assists in control of the aerial vehicle with user intervention through the mobile device, wherein assist in control is further performed through the command and control system and at least one attachment attachable to the aerial vehicle for facilitating the task performed to the object by the aerial vehicle while the aerial vehicle is in the aerial mode, the at least one attachment is controlled by the removable mobile computing device. Methods are also disclosed.
Abstract:
A method automatically controls the movement of a winch device (2), which is adapted to pull in or let out a cable (T), to which at least one flying device 4 is connected. The method includes the following subsequent steps: a) determining the relative position between the winch device (2) and the flying device (4); b) calculating the optimal length of the cable “T” as a function of the relative distance determined during the previous step; c) activating said winch device (2), so as to obtain the desired length of the cable “T” calculated during the previous step; d) repeating the sequence of steps a)-c) for a desired amount of time; in order to obtain, in real time, the optimal length of the cable (T) as a function of the changes in the relative position between the winch device (2) and the flying device (4).
Abstract:
Wind energy systems, such as an Airborne Wind Turbine (“AWT”), may be used to facilitate conversion of kinetic energy to electrical energy. An AWT may include an aerial vehicle that flies in a path to convert kinetic wind energy to electrical energy. The aerial vehicle may be tethered to a ground station with a tether that terminates at a tether termination mount. In one aspect, the tether may be a conductive tether that can transmit electricity and/or electrical signals back and forth between the aerial vehicle and the ground station. The tether termination mount may include one or more gimbals that allow for the tether termination mount to rotate about one or more axis. In a further aspect, the tether termination mount may include a slip ring that allows for rotation of the tether without twisting the tether.
