An aircraft that can fly stably when water is discharged from a hose installed on the airframe, and an aircraft system, are provided. The aircraft system can include a master aircraft, slave aircrafts and a remote control device. The aircraft preferably fly as a unit. Each slave aircraft can include four rotary blade portions having propellers, and a suspending means for suspending a part of a hose. The master aircraft may include four first rotary blade portions having first propellers arranged to rotate in a horizontal plane, four second rotary blade portions having second propellers arranged to rotate in a vertical plane, and a nozzle on which a tip end part of the hose is installed. The direction of the center axis of the nozzle is parallel to the direction of the rotational axes of the second propellers.

A system for remote care of an animal includes a smart bowl that includes an open-faced container for holding a substance, a microprocessor, and a proximity sensor configured to detect the presence of a proximity tag attached to an animal.

Presently disclosed subject matter integrates a method of using thousands of semi-autonomous unmanned aerial vehicles, herein called drones, to deliver vastly superior amounts of fire retardant over substantially larger and variably-shaped drop patterns. Each drone is able to swap its own batteries with freshly charged batteries and each drone is able to refill its container with water or fire retardant. Once launched, a swarm of drones can perform repeated trips from the water/retardant source to the fire without human involvement other than the high-level tasking of where to drop the retardant. Once a general drop destination and drop pattern shape is designated, the swarm can transport retardant to that location, form itself into the desired drop shape, and deploy retardant. The drone body is designed to be modular so different components can be attached with ease and no special training or knowledge required.

A fire suppression drone comprises a main body, a plurality of propellers provided on an outer circumference of the main body and driven by a driving motor, a pump provided in the main body and connected to a water feeding vehicle through a water feeding hose, at least one water jet nozzle provided on the outer circumference of the main body to jet water supplied by the pump, a camera provided on the outer circumference of the main body, and a controller connected with the driving motor, the pump, and the camera and connected with a remote controller to be wirelessly communicable with the remote controller, wherein the remote controller includes a monitor, the monitor capable of display, in real-time, an image captured by the camera.

A disposable unmanned aerial glider (UAG) with pre-determined UAG flight capabilities. The UAG comprises a flight module comprising at least one aerodynamic arrangement; and a fuselage module comprising a container configured for storing therein a payload and having structural integrity. The container is pressurized so as to maintain structural integrity thereof at least during flight, so that the UAG flight capabilities are provided only when the container is pressurized.

A first drone equipped with a high energy Directional Ultrasound Parametric Speaker Array and a second drone equipped with an Acoustic Dispersion Cannon are used to fight wildfire. The first drone is distanced far from a burning flame but in close proximity to a fire target. Both drones are guided by GPS to communicate with remote operators. Once the target is locked, the first drone blasts the target with Amplitude Modulated Ultrasound. The Ultrasound is self-demodulated into a lower frequency audio sound when it encounters a hot flame of richly charged ions. The lowered frequency sound pushes and pulls the flame forward and backward rapidly away from the combustion source, causing it to be disconnected from the flame which instantly cools down and is extinguished. The second drone blasts the combustible source with powerful sonic shockwaves to disperse the still hot particulates further apart to prevent the source being reignited.

A method of and system for helping building construction team members in significant ways: (i) quickly detect high-risk fire outbreaks and arson strikes to a wood-framed and mass timber buildings under construction; (ii) receiving automatic notifications when fire outbreaks and arson strikes are detected at GPS-specific regions in a building under construction, and (iii) automatically and quickly responding to the detected fire outbreak and/or arson strike using AI-guided and/or VR-guided thermal-imaging flying drones, and AI/guided and/or VR-guided thermally-imaging fire seeking and suppressing robots and drone systems which eliminate these fire outbreaks by directly controlled spray streams of clean anti-fire (AF) liquid on the fire, using only of the water required using conventional fire extinguishing methods.

A system and method directed to an inflatable aerial beam transported by aerial vehicles for dispensing, among others, power and fluids using the inflatable aerial beam that may be mounted between two or more aerial vehicles. The beam, may become rigid when inflated or flexible when deflated. The beams may be coupled to one or more aerial vehicles via a pivotable joint or a flexible juncture to maintain flexibility of movement of the aerial beams. The beams may include a fluid dispenser that distributes fluid to spray nozzles to dispense fluids from the inflatable beam. The fluid, chemicals, and/or power may be obtained from a remote fixed or mobile source, one or more aerial vehicles, and other types of aerial vehicles. The aerial vehicles may be controlled remotely from a fixed location or from a movable remote-control source and may include sensors for navigation and for controlling the dispensing of the fluid or power.

Methods and systems for fluid supply. In one example, a system includes a conduit for supplying pressurized fluid therethrough and having a proximal end configured for being connected to a fluid source and a distal end with a supply outlet for dispensing said fluid in a first direction. The conduit further includes at least one jet outlet configured to provide a jet fluid flow in a second direction other than the first direction, exerting thereby thrust on at least a portion of said conduit in a third direction. And a tilting mechanism configured to tilt said at least one jet outlet thereby adjusting said third direction.
