Abstract: This document describes an unmanned aerial vehicle (UAV) configured to navigate an unmanned aerial vehicle highway. The UAV includes a navigation system that includes a sensor, configured to gather environmental data, and a computing system configured to navigate the UAV. The computing system compares the environmental data to a specified data signature in the one or more spectra and determines a position of the unmanned aerial vehicle in the unmanned aerial vehicle highway. The UAV includes a hybrid generator system including an engine configured to generate mechanical energy and a generator motor coupled to the engine and configured to generate electrical energy from the mechanical energy generated by the engine. The UAV includes a rotor motor configured to drive a propeller to rotate. The navigation system is powered by the electrical energy generated by the generator motor.

Abstract: A non-contact passive ranging system wherein a first imager on a platform is focused on a first object and a second imager on the platform is also focused on the first object. The optical path from the first object to the first imager is configured to be shorter than the optical path from the object to the second imager. Processing circuitry is responsive to an output of the first imager and an output of the second imager as relative motion is provided between the platform and the first object and is configured to calculate the distance from the platform to the object.

Abstract: An aquatic device is usable in an aquatic environment for a variety of purposes, such as physical therapy, rehabilitation, and/or exercise. The aquatic device permits a person to simulate a walking or running gait cycle in the aquatic environment, reducing the stress/strain associated with walking or running on the ground. An aquatic device includes a foot-receiving member rotationally coupled to a fin member. The fin member, when in an extended position, provides increased resistance as the person attempts to walk or run in the aquatic environment. During a walking or running gait, the fin member moves into a folded position, thus reducing the resistance of the water on the aquatic device. The aquatic device is adaptable and modifiable to have varying shapes, designs, sizes, resistance levels, and/or other aspects.
