A marine drone system utilizing an unmanned aerial vehicle to provide visual feedback for conditions including temperature, depth, and conditions which may suggest favorable fishing conditions, such as weed lines, flotsam, breaks, and objects, such as birds or fish. The system utilizes a plurality of sensors, including, but not limited to, cameras, laser, GPS, radar, and LIDAR. The visual feedback may be shown as a video fees or a map, wherein the feedback is shown as a visual backgrounds, wherein an overlay of interactive functions provides information regarding the conditions. The system also includes method steps for implementing, obtaining, and displaying the information. The system hardware includes the unmanned aerial vehicle, a base station, and a hardwired tether between the unmanned aerial vehicle and the base station providing power and bi-directional data transfer.

A multi-modular aerial firefighting control method and apparatus for use by firefighters to control fire. The multi-modular aerial firefighting control method and apparatus generally includes multi-modular units that are held together to form an aerial firefighting system. The modular units may work together or independently. The multi-modular system comprises more than one modular unit, fluid, fluid conduit, reservoir, air flow generator, multi-modular unit support structure, aerial suspension system and aerial lift system.

A system and a method are provided for achieving long range, over the horizon (OTH), persistent surveillance, alerting, tracking and situational awareness against small, low radar cross section moving targets. The system and method use one or more tethered unmanned arial systems, or unmanned arial vehicles, to lift components including a radar antenna to a height above nearby obstacles or much higher. The system and method can also be used for subsurface radar detection and tracking applications, as well as communications with submarines.

A patient transfer device. According to one embodiment, there is provided a patient transfer device: a support part including a patient seating surface on which a patient is supported; a plurality of propeller parts, connected to the support part, for moving the support part; a power supply unit to be transported while being borne by the user, the power supply unit serving to supply power to the plurality of propeller parts; and a connection member connecting the power supply unit and the support part, wherein the support part is configured to move to follow the power supply unit.

An unmanned aircraft system 100 built off of a purpose-built transmission infrastructure 300 with a power collector 400 riding along the infrastructure 300 connected to a tether 500 that is electrically connected to both the infrastructure 300 through the power collector 400 and also connected to an unmanned aircraft carrying associated electronics that are powered through the tether.

A tethered aerial system includes an on-board fuel cell for powering on-board electronics and a tether cable which is less conductive than air. The tether cable includes a pipe for carrying a flow of gas to the fuel cell and/or maintain the gas level in a lighter-than-air platform, so that the tethered aerial system can remain operational for an extended period of time. The system is particularly applicable for maintaining communication links in remote areas, agriculture and applications in the IoT (Internet of Things), event coverage, interactive marketing, for post-disaster situations in rural areas and at mining sites or construction sites in remote environments. The system also is immune to rays.

The present invention relates to an atmospheric environment-improving drone having life-saving and advertising functions, and more specifically, to a drone configured to move while hovering in the air, the drone comprising: a drone body; and a hovering transport unit for hovering the drone body in the air and moving same. The drone body is provided with a water spray means for purifying the air by adsorbing dust and fine dust in the air. The water spray means includes: support shafts, each of which has one end fixed on the outer surface of the drone body; spray liquid supply pipes fixed to lower portions of the support shafts; and spray liquid spraying nozzles formed at regular intervals on the purified liquid supply pipes. Since the drone configured to move while hovering in the air is used to spray water from the air, the drone can spray a wider area than ground-based water spray devices, thus having the effect of improving the purification efficiency for contaminants or fine dust in the air. Moreover, the drone has an advertising function, and thus can also achieve an advertising effect.

The invention relates to a protection device for protecting the connection between a detachable wired drone (1) and the wire (5) thereof. This device enables the plug (3) to be reused even when it has fallen many times from a great height and limits the risk of injury and electrocution of people. The device consists of a non-conductive envelope surrounding the electrical contacts of the plug (3), a procedure or a mechanical system that cuts off the power when the plug (3) is detached from the drone (1), a system for mechanical protection against impacts, which can be an energy-dissipating envelope, a parachute-like system (4) for slowing down the fall, or the separation of the plug into a plurality of parts connected by a flexible element. The device according to the invention is particularly applicable to wired drones (1) in order to speed up movement outside the perimeter defined by the wire (5).
