Abstract: A propulsion rudder for use with a water vessel, preferably an unmanned surface water vessel. The propulsion rudder includes a rotating base, a rudder assembly, and a thrust assembly. In one embodiment, the rudder assembly may comprise two vertical mast rudders connected by an upper horizontal wing, with the thrust assembly mounted on the horizontal wing. In a second embodiment, the rudder assembly may comprise an annular airfoil with the thrust assembly mounted on a mast and positioned in the center of the annular airfoil. The thrust assembly may be a propeller, a turbine, a ramjet, or a rocket.

Abstract: A camera drone has an array of eight camera-light units arranged so as to enable capture of photographs and video providing a spherical 360°×360° field of view. Such an expansive field of view enables image capture for use in virtual reality, augmented reality, and similar uses. The camera drone is preferably spherical in shape so as to minimize any obstructions in the expansive field of view. The camera drone is modular with separate but coordinated modules for a main body module, a base module along an equator of the main body, a thruster module, and a camera-light module. The camera drone is also capable of operation in air or water (submersible) having both a tethered and autonomous version.
