USING A PASSIVE SEPARATOR TO SEPARATE AIR AND FUEL OF A FUEL MIXTURE PASSIVELY WHEN DELIVERING FUEL TO A COMBUSTION ENGINE OF AN UNMANNED AERIAL VEHICLE
A fuel delivery system has a tank, a fuel pump, and an air filtering apparatus coupled with the tank and the fuel pump. The air filtering apparatus includes a housing that defines a housing chamber, a fuel flow controller coupled with the housing, and a passive separator disposed within the housing chamber. The passive separator is constructed and arranged to separate air and fuel of a fuel mixture passively while the fuel mixture enters the housing chamber from the tank and while filtered fuel exits the housing chamber toward the fuel pump in response to operation of the fuel flow controller. Such a system is well-suited for supplying fuel to a combustion engine in which consistent fuel pressure may be critical. Furthermore, the passive separator alleviates the need for a power source for active air and fuel separation, a control mechanism, and so on.

A technique for adaptively disrupting UAVs detects a target UAV using a camera, monitors the target UAV's communications using a directional antenna aligned with the camera, and attempts to communicate with the target UAV to request that it land, fly away, or return to launch. With the camera trained on the UAV, the directional antenna detects down-link signals from the UAV, which the UAV may employ to communicate with a ground-based controller. Control circuitry analyzes the down-link signals and generates a disrupting signal based thereon. The disrupting signal shares characteristics with the down-link signal, such as its protocol, bit rate, and/or packet length. The directional antenna transmits the disrupting signal back toward the UAV to affect the UAV's flight.
