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.

An unmanned vehicle capable of operating in harsh environments is disclosed. The unmanned vehicle includes an aerial platform, a piloting system supported by the aerial platform, a medium source supported by the aerial platform, and a control system having a processor running computer executable code that actuates the medium source to emit a medium away from the aerial vehicle with an intensity sufficient to disorient a subject when the medium interacts with an exteroceptive sense of a subject.

Airborne unmanned autonomous vehicles (UAVs) may be used to hover over swimming pools or spas and dispense chemicals (or other materials or devices) directly thereinto. UAVs alternatively or additionally may include sensors designed to identify certain characteristics of pools or spas or of the water therein. The UAVs further may hover over, or land on, pool pads or other areas adjacent or near a pool or spa to deliver or receive parts or other objects.

A pump body assembly, a pump, a sprinkler system, and an unmanned aerial vehicle are provided, the pump body assembly including a drainage outlet on a pump housing and a valve body portion of a valve core member, where the valve body portion is elastic, and the valve body portion changes from a natural state to an elastic deformation state under an action of liquid in the pump housing, such that when the valve body portion is in the natural state, the valve body portion seals the drainage outlet of the pump housing, and when the valve body portion is in the elastic deformation state, the valve body portion does not seal the drainage outlet of the pump housing.

A smart agent container cover (100), a smart agent container, and an aircraft are provided. The smart agent container cover (100) includes an upper cover (11), a lower cover (10), a control module (3), a liquid level measuring module (2), a communication module (4), and a power supply module (5). The upper cover (11) and the lower cover (10) define a sealed accommodating space therebetween. Electronic components, such as the control module (3), the communication module (4), and the power supply module (5), are all arranged within the accommodating space, and have no electrically conductive physical contact with an external environment. During use, only the liquid level measuring module (2) is submerged below a liquid surface, such that the electronic components are better protected, thereby ensuring the stability and accuracy of liquid level measurement, prolonging the service life of the smart agent container and the agent container cover (100) thereof, and guaranteeing precise spraying by an unmanned aerial vehicle.

An unmanned aerial vehicle includes a body, a propulsion system connected to the body. The propulsion system generates a lift force in a vertical direction opposite of a gravitational force when activated. In some cases, the unmanned aerial vehicle includes an applicator connected to the body. The applicator includes a channel, a chamber in fluid communication with the channel, and a nozzle in fluid communication with the channel.

Devices, such as mobile sensors and static sensors, monitor field health. A comparison to a baseline may facilitate detection of a field health issue. When an issue with field health is determined, a remedy may be deployed. Deploying a remedy may use an unmanned vehicle, such as an unmanned aerial vehicle, or a liquid distribution manifold.

Provide is an agricultural chemical spraying drone with improved safety. An acceleration sensor and a contact detection sensor are combined to detect contact of a drone with an obstacle. In a case where the contact is detected, a retreat action such as hovering is taken. In addition, a message may be displayed on a control terminal, a warning sound may be generated, and a warning light may be turned on. Further, a structure capable of minimizing finger insertion accidents and minimizing interference with a rotor even in collision is adopted as a propeller guard.

A system and method to distribute pesticides, fertilizers, water, and other materials on a farm with accuracy and precision is disclosed in order to combat the problems imposed on the environment due to over-fertilization and over use of pesticides. This system and method is a social networking control system in which multiple farms have independent grids of sensors capable of detecting the presence of pesticides, fertilizers, water, and other materials in the air, in the top-soil, and in the groundwater. These grids of sensors detect the location and concentration of these materials and reports them back to a social control system for analysis. The control system regulates the deposition of further chemicals through computer control of the chemical dispersal systems.

The present invention relates to an unmanned aerial vehicle (10) for spraying an agricultural field. The UAV has a liquid reservoir (20), a liquid spray gun (30), and a plurality of sets of rotor blades (40). The liquid spray gun has a spray axis extending away from the liquid spray gun. Each one of the plurality of sets of rotor blades is connected to a corresponding one of a plurality of drive shafts (50). A first drive shaft (51) of the plurality of drive shafts has a first drive axis extending longitudinally through the first drive shaft that is configured to be at a first angle to the spray axis. A second drive shaft (52) of the plurality of drive shafts has a second drive axis extending longitudinally through the second drive shaft that is configured to be at a second angle to the spray axis. The first drive axis and second drive axis are located in substantially the same first-second plane. The first angle extends away from the spray axis in a first direction and the second angle extends away from the spray axis in a second direction. The first direction is different to the second direction The liquid product ejected from the spray gun is at least partially entrained by a downwash of air from a first set of rotor blades connected to the first drive shaft and by a downwash of air from a second set of rotor blades connected to the second drive shaft.
