Abstract: A vape cleaning device for easily and thoroughly cleaning vape coils for reuse and avoiding the need for frequent replacement. The device has a base enclosing a fan oriented to direct air upwardly, a heat block suspended above the fan, a heating element coupled to the heat block, and a shield coupled to the base and having a central opening. A cup is removably positioned in the central opening of the shield and in contact with the heat block to be heated thereby. A vape coil holder may removably suspended in the cup that the vape coil is submerged in a cleaning fluid in the cup. After the cup has been warmed to a predetermined temperature for a cleaning cycle, the cup may be removed and the vape coil holder suspended from the shield. The fan may then be operated for a predetermined time period for a drying cycle.

Abstract: Systems, methods, and devices are provided that enable robust operations of a small unmanned aircraft system (sUAS) using a compound wing. The various embodiments may provide a sUAS with vertical takeoff and landing capability, long endurance, and the capability to operate in adverse environmental conditions. In the various embodiments a sUAS may include a fuselage and a compound wing comprising a fixed portion coupled to the fuselage, a wing lifting portion outboard of the fixed portion comprising a rigid cross member and a controllable articulating portion configured to rotate controllable through a range of motion from a horizontal position to a vertical position, and a freely rotating wing portion outboard of the wing lifting portion and configured to rotate freely based on wind forces incident on the freely rotating wing portion.

Abstract: A self-contained avionics sensing and flight control system is provided for an unmanned aerial vehicle (UAV). The system includes sensors for sensing flight control parameters and surveillance parameters, and a Global Positioning System (GPS) receiver. Flight control parameters and location signals are processed to generate flight control signals. A Field Programmable Gate Array (FPGA) is configured to provide a look-up table storing sets of values with each set being associated with a servo mechanism mounted on the UAV and with each value in each set indicating a unique duty cycle for the servo mechanism associated therewith. Each value in each set is further indexed to a bit position indicative of a unique percentage of a maximum duty cycle for the servo mechanism associated therewith. The FPGA is further configured to provide a plurality of pulse width modulation (PWM) generators coupled to the look-up table. Each PWM generator is associated with and adapted to be coupled to one of the servo mechanisms.
