Abstract:
A ducted fan core for an unmanned aerial vehicle is provided that accommodates a wide variety of payloads. The ducted fan core comprises a frame, attached to which are an engine, gearbox assembly, fan, and a plurality of control vanes. A first surface on the frame comprises a plurality of connects or electrical traces. The plurality of connects are used to removably attach a variety of pods carrying various payloads. Thus, a wide variety of payloads may be delivered using the same unmanned aerial vehicle, simply by removing and attaching different pods to a fixed vehicle core. These pods may be shaped so as to form part of the vehicle exterior, and when the pods are attached to the frame, they enhance the aerodynamics of the vehicle.
Abstract:
A system and method for transmitting UAV position data to a central flight control center transmits UAV position data using a virtual transponder. A ground control station for controlling the UAV receives data from the UAV, including UAV position data. The UAV may provide GPS data, or corrected position data based on readings from an inertial navigation system. The ground control station transmits the UAV position data to a flight control center.

This non-provisional patent filing is a follow-on to U.S. Pat. No. 8,421,636 B2 issued Apr. 16, 2013 and is to document the development work done between the original patent filing and continued product research and development. With increased interest in the realm of incontinence wetness sensing in adults and children within a wide variety of conditions, there is always at the core of the sensing, the need for accuracy. Without accurately predicting a wet event, a system rapidly becomes useless and is abandoned. Ongoing development and implementation of incontinence wetness sensing, in a wide variety of venues has identified significant limitations in current incontinence monitoring systems. In theater test and development data has shown that with any incontinence wetness sensing that key measurement parameters vary much more widely than previously predicted. The measurement accuracy of these parameters can significantly affect the reliability of wetness sensing second, third and fourth wet events of an incontinent product. This patent claims the implementation of a wide dynamic range sensing system that utilizes digital variable resistance, capacitance or other measuring technique. This new sensing method, uniquely adapts to the incontinent product environment significantly improving the sensing range and tailored response. The use of these configurable elements allows for modification in real time by microcontroller or other controlling device of the reference in wetness sensing applications enabling this in system dynamic reconfigurable capability.
Abstract:
A ducted fan air vehicle having increased storage capacity inside the duct for equipment and electronics provides improved airflow and fan efficiency over ducted fan air vehicles carrying cargo in external pods. The outside of the duct may extend outwardly to allow equipment and electronics to be stored inside the duct in storage areas located at intervals along the duct. The storage areas may form a square duct having a circular inside wall. Additionally, the storage areas may extend in the direction of the axis of rotation of the fan to provide additional storage above the lower lip of the duct.
Abstract:
A fuel line air trap for an unmanned aerial vehicle has a vessel in-line with a fuel line, fuel line connectors, and fuel inlet and outlet stems. The vessel contains an inlet at a distal end and an outlet at a proximal end. The fuel line connectors are attached to the vessel at the inlet and at the outlet to connect the fuel line to the vessel. The fuel inlet stem attaches to the vessel at the inlet and a fuel outlet stem attaches to the vessel at the outlet. Both the fuel inlet stem and fuel outlet stem protrude into the vessel a predetermined distance such that a gap exists between them. As air bubbles enter the gap in the fuel line air trap, they separate from the flow of fuel and migrate to the exterior walls of the vessel. The air bubbles are purged during remain trapped refueling.
Abstract:
A structural ring interconnect printed circuit board assembly for a ducted fan unmanned aerial vehicle that comprises a printed circuit board attached to a core vehicle body, wherein the printed circuit board conforms to the shape of the core vehicle body's airframe skirt, and wherein the printed circuit board provides structural integrity to the core vehicle body.
