Abstract: A compact and lightweight, drone delivery device propelled by an electric ducted air propulsion system. The device is called an ArcSpear Electric Jet Drone System and is relatively difficult to track in flight (stealth), relatively fast, able to maneuver quickly, and able to be re-deployed after recharging and replenishing the payload. The system includes a frame carrying the propulsion system, payload, and controls. The frame structure supports a flight controller and a ducted turbine system with at least one and preferably four turbines the blades/impellers being secured inside a protection shroud/duct and individual electric motors that are powered by rechargeable batteries.

Abstract: An improved system of electrical, battery operated propulsion for use by an individual when engaging in paragliding, powered paragliding, paramotoring, hang gliding, and other similar sporting activities. The system includes a lightweight frame; at least one electrical driven, ducted turbine system made of at least one turbine, a shroud with a cut protector, and an electric motor; a seat assembly; a seat belt, and a pair of shoulder straps to hold user to the seat; a power system with a set of rechargeable batteries, battery boxes, a wiring harness from batteries to motors; and a servo-throttle for powering a motor of the system.

Abstract: Disclosed is a Personal Electric Helicopter device with an integral wind turbine recharging capability. The device is a relatively small, lighter weight powered aircraft capable of vertical take-offs and propulsion across various terrain at low altitudes. The device is uniquely capable of re-charging its power source by connection to an electrical grid or by using its uplift components as a wind turbine for re-charging. The preferred embodiment is comprised of a rechargeable uplift and propulsion power system with components and features; a frame structure to carry an operator and/or payload; a means to connect the structure to the power system; and a means to control the uplift and propulsion system wherein the vehicle may be used to elevate and propel a payload at low altitudes across various terrains and may be positioned to reverse power the wind turbine to recharge the batteries.

Abstract: A method or device uses a dazzling laser light and an acoustic energy wave to non-lethally immobilize a person or animal. In some embodiments, the distance to the target is used to control the intensity of the dazzling laser light source striking the target subject and the acoustic energy output power.
