Abstract: A gearbox assembly includes a planet gear including an outer surface and an inner surface opposite the outer surface. A pair of circumferential oil channels are formed in the inner surface proximate opposite ends of the planet gear. A distributor channel is formed to extend in a longitudinal direction toward a center of the planet gear from each circumferential oil channel. One or more tooth channels are formed to extend from each distributor channel to the outer surface of the planet gear. A journal pin is received within the planet gear extending along an axis about which the planet gear rotates. A gap defines a journal bearing formed between the inner surface of the planet gear and the journal pin. An oil passage is provided supplying oil to the gap.

Abstract: The present invention provides a system for control and guidance of an unmanned aerial vehicle (UAV) using modulated laser light in radio frequency (RF) contested environments. The system enables the user to send light signal communications to the UAV from a handheld device. In one embodiment, where the handheld device is capable of being incorporated into a firearm fore-grip with built-in controls that allow for control of the UAV by a user in a shooting/aiming position. The UAV includes an optical array for detecting and receiving the light signal communications, as well as filtering systems for filtering out unnecessary image data for better control in different weather and time conditions, as well as an avoidance system to avoid objects and other UAVs when used in a swarm of UAVs.
