Abstract: A drone receives an initiation signal which indicates that flight and/or navigation components of the drone are to be activated. Once activated, the drone then determines its initial position using a position-identifying radio signal. The drone then retrieves, from storage, dimensions of a drone-relative geofence. The drone can then calculate, using a processor, the drone-relative geofence having the dimensions with at least a specified floor and a specified radius. The drone adjusts the motor controller inputs to prevent the drone from exiting the calculated drone-relative geofence.

Abstract: The objective of the device is to spray sun care products out of a hand sprayer and can be moved from customer to customer.

Abstract: A low voltage, portable, outdoor spray system for applying sunscreen to a user. The system is comprised of a booth having a floor and at least one wall defining an enclosure. At least one spray nozzle is positioned within the enclosure and is connected to a pump. The pump in turn is connected to a reservoir tank, which may hold a sunscreen lotion, a tanning lotion or a aloe vera lotion. The spray system also includes an automated payment system. Once payment has been verified, a microcontroller sends a signal to the pump to begin operation. The pump draws lotion from the reservoir tank and delivers the lotion to a check valve. Upon reaching a predetermined pressure, the check valve opens and releases the lotion through the spray nozzle and onto the user.

Abstract: An electric motor pressurized line and tank provide a cosmetic solution through a hose loop to an array of spaced stationary spray nozzles in a spray booth. A microprocessor automatically opens solenoid valves in the hose loop for spraying the cosmetic solution into the spray booth and drawing unused cosmetic solution back into the tank. A water spray and nozzle cleans the spray booth and a drainage tank with a pump forces drainage out a drain opening in the bottom of the booth and into the drainage tank.
