Systems and methods for the use of unmanned aerial vehicles (UAVs) in medical emergencies are disclosed herein. The systems and methods include receiving at a first UAV an indication of a medical emergency and coordinating with a second UAV based on the second UAV's capabilities. The first UAV determines if the capabilities of the second UAV complement the capabilities of the first UAV based on the indicated medical emergency. The disclosed systems and methods deploy both the first and second UAVs to the medical emergency if the capabilities of the second UAV complement those of the first UAV.

The present invention relates to a fire extinguishing firefighting drone which, in case of a fire in a house, a structure, a building, or the like, can be rapidly introduced and extinguish a fire in an early stage of the fire, and can be remotely operated in an unmanned manner through connection with a central control system. The fire extinguishing firefighting drone includes a flight unit configured to include propeller units, a disaster prevention turret unit configured to spray a fire-extinguishing chemical, a plurality of movement units configured to move a body unit, and a disaster prevention means unit configured to be provided with items adapted to spray a fire-extinguishing chemical, to launch a fire-extinguishing bomb, or to save lives.

A system and method for tracking the growth of large-area wildland fires. The technique includes monitoring wind conditions in and around a wildfire using near-surface-sited sensors deployed by a high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV), such as the Global Hawk. The deployed sensors measure a localized wind vector at multiple locations within and surrounding the wildfire, and transmit the wind data back to the UAV for relaying to a command center operated by fire management authorities, where the wind data are used to assist decision-making, including as input into wildfire growth prediction models. The sensors may provide additional data such as local altitude/elevation, pressure, temperature and relative humidity. The UAV may also carry sensors that provide additional data to be used by the fire management authorities or the wildfire growth prediction modelssuch as infrared images defining actively flaming areas, and visual images which indicate vegetation type and density.

Unmanned Aerial Systems (UAS) for use in the detection, localization, and quantification of gas leaks are provided. More specifically the use of an in-situ sensor mounted to a UAS such that the sensor is positioned in a region unaffected by prop wash that is relatively undisturbed by the effects of the propeller(s) and other environmental conditions when in use is described. Additionally, methods of determining the optimal placement of the in-situ sensor on any given UAS are also provided.

A firefighting aircraft adapted for use in an unmanned aircraft system includes a storage tank for firefighting fluid, having a plurality of filling ports spaced from one another. A probe carries a conduit that is in fluid communication with the storage tank. The conduit receives water from a body of water overflown by the aircraft. A filling system for controls the flow of water to and from the storage tank, and includes a remotely and automatically operable valve respectively associated with each filling port. A control system is in communication with each valve, and is operative to command the position of each valve to regulate the flow of fluid through each filling port. A baffle may be further provided internal to the storage tank at least partially defining a first chamber within the tank. The baffle may include one or more baffles, and be provided substantially vertically, horizontally, parallel with or transverse to a longitudinal axis of the aircraft, or otherwise, and is operative to contain water entering the tank through the filling port, substantially filling the first chamber before filing any other portion of the storage tank.

Multi-rotor aerial vehicle (1, 1, 1, 1, 1, 1, 1) comprising, at least a first, second and third rotor 10, 20, 30, each rotatable by a dedicated first second and third hydraulic motor 11, 21, 31, a power unit 2, at least a first, second and third hydraulic pump 12, 22, 32 dedicated to the respective first, second and third hydraulic motor 11, 21, 31, wherein each hydraulic pump 12, 22, 32 is arranged to provide pressurized fluid to each hydraulic motor 11, 21, 31 for powering the hydraulic motor 11, 21, 31 and thereby rotating the respective rotor 10, 20, 30, a control unit 6 for controlling the operation of the multi-rotor aerial vehicle (1, 1, 1, 1, 1, 1, 1), wherein the control of the multi-rotor aerial vehicle (1, 1, 1, 1, 1, 1, 1) is arranged to be performed by altering the flow of pressurized fluid distributed to each respective hydraulic motor 11, 21, 31, wherein, wherein the flow of pressurized fluid provided to each hydraulic motor 11, 21, 31 is individually controllable by means of at least one control valve 13, 23, 33 configured to control the flow of pressurized fluid from each hydraulic pump 12, 22, 32 to its dedicated hydraulic motor 11, 21, 31.

A disclosed method includes monitoring a plurality of emergency event queues at an emergency network entity; determining that an emergency event in one of the emergency event queues corresponds to an emergency type that can be responded to using an unmanned aerial vehicle; determining that an unmanned aerial vehicle is available that has capabilities corresponding to the emergency type; establishing an unmanned aerial vehicle control link between the unmanned aerial vehicle and the emergency network entity; and deploying the unmanned aerial vehicle to the emergency event location and providing data from the unmanned aerial vehicle on a display of the emergency network entity.
