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.

A search and rescue drone system includes a buoyant body member, a frame attached to the buoyant body member for carrying a motor and propeller, and an electronic array including a camera, GPS, an EPIRB radio distress beacon, and a transmitter/receiver for remote control flying the drone and communicating with an operator. A laser guidance system may provide coordinates for landing near a swimmer in distress. The search and rescue drone may also be programmed to simply fly to the location of an electronic wearable device, like a bracelet, that is worn by a man overboard. In another embodiment, the search and rescue drone includes pivoting motor mounts, so that it can take off and land vertically with propellers rotating in a horizontal plane, and then the propellers may pivot to rotate in a vertical plane for propulsion across water similar to a fan boat with rescued people aboard.

A modular autonomous aerial passenger vehicle is provided to automatically transport any person or luggage or capable of being used by the defense organizations for monitoring without any interference or need of human pilot. The autonomous aerial vehicle is comprising of an aerodynamic main body having 4 fixed arms each and 2 foldable arms each of which further having a pair of propellers coupled at the edge of each foldable arm, one at the top and one at the bottom. Further, the autonomous aerial vehicle further includes a power management system; safety system; interior cockpit having a HMI and seating arrangement, where the HMI is a brain computer interface that acquires signals from the brain and analyses them to convert it into commands. It includes a display unit and manual control unit; primary and auxiliary battery modules, flight control unit, plurality of sensors and cameras and other safety equipment for safe functioning of the present autonomous aerial vehicle.

An air transport vehicle that capitalizes on the strengths and complexities of a fixed and rotary winged aircraft. The air transport vehicle comprises a body aerodynamically designed to avoid substantial drag. The vehicle has a plurality of rotors configured to generate vertical thrust with a rear rotor configured to generate forward thrust. Additionally, each of the rotors are connected to the fixed wing elements and the fixed wing is positioned about the center of mass of the fuselage. Furthermore, each of the rotors are positioned at a fixed tilt angle such that the stability of the vehicle is maintained in a number of different flight configurations.

An unmanned aerial system (UAS) may comprise an unmanned aerial vehicle (UAV) configured to search and recover persons and things, collect and produce data of an emergency situation for display on a vehicle navigation system, or explore for natural resources. The UAS may include a landing pad, and/or a sensor such as a ground penetrating sensor configured to search for a person trapped underground. The UAS may be configured to receive data from the one or more sensors. An analyzer may be used to assess surrounding environment and the status of the person or thing, and send a signal to the UAV. The components attached to the UAV may include connectors, a robotic arm, a sensor, and/or a portable power source. The UAS may be configured to, for example, detect an emergency situation and determine the nature and location of the emergency situation. The UAS may be configured to explore for oil, gas, and mineral sources, and/or excavate location using a robotic arm.

Modular add-on structures may be connected to a structure, such as a multi-rotor flight vehicle, using connection and release apparatuses. Replacement modules may be interchanged in one or more locations on the platform structure, and may provide an operating component that enables a capability once added, such as a medical bed for medical evacuation, a seat for manned flight control, a seat for passive riders, a cargo hold for the transportation of cargo, a cargo hold for transportation of an aid package, a liquid dispersing mechanism for dispersion of a liquid, other projectile disbursement mechanisms for disbursement of other non-liquid or projectile disbursement, flight through propulsion enabling attachment. A flight vehicle, such as a multi-rotorcraft flight vehicle, may support different capabilities and functionalities, where the design of the multi-rotorcraft, modular add-on structures, and multi-rotorcraft functionality, configuration, control, and shape, enable different uses, capabilities, and functionality.

A search and rescue drone system includes a buoyant body member, a frame attached to the buoyant body member for carrying a motor and propeller, and an electronic array including a camera, GPS, an EPIRB radio distress beacon, and a transmitter/receiver for remote control flying the drone and communicating with an operator. The search and rescue drone may be flown manually, or may have some autonomous flight and locator capabilities. For example, in one embodiment, the search and rescue drone may be programmed to simply fly to the location of an electronic wearable device, like a bracelet, that is worn by a man overboard. In another embodiment, the search and rescue drone includes a basket, harness, or other means for actually recovering a swimmer in distress, and flying that person back to safety on a ship or on shore.
