Abstract: A system and method for transient satellite doppler signal position determination by receiving multiple measured signals, determining transmission characteristics for those signals, determining orbital characteristics of satellites associated with those signals via a Doppler calculation, identifying the satellites from the transmission and orbital characteristics, determining a closest approach point responsive to identifying the satellites and the Doppler calculations, determining current positions of the satellites relative to the receiver from the closest approach point determinations via comparison to an orbital location-defining modeling equation associated with the first satellite, and determining a geolocation of the receiver responsive to each of the current position of the satellites relative to the receiver.

Abstract: A propeller system including a propeller including a central attachment member and a plurality of blade apparatuses, each including a blade body attached to the central attachment member and a magnetic coupling member attached to a radially outward end of the blade body. The propeller system further comprises a propeller frame configured to at least partially circumscribe the magnetic coupling member of each blade apparatus and a plurality of electromagnets positioned on the propeller frame and operable to generate magnetic fields to suspend the magnetic coupling members, laterally translate the magnetic coupling members, rotate the magnetic coupling members along the radial axis of the propeller system, thereby rotating the blade bodies.

Abstract: An energy storage apparatus including a spherical rotating member having permanent magnets and uniquely-identifiable location-defining elements, a plurality of coils, a controller operably coupled to the plurality of coils, a power source, and a location sensing apparatus operable to detect the plurality of location-defining elements. The controller may compare time-sequential information from the location sensing apparatus to determine a rotational axis and a rotational speed of the rotating member, operate the coils to change the rotational axis speed of the rotating member, increase energy stored by the rotating member by increasing the rotational speed by operating the coils to generate magnetic fields that interact with the permanent magnets, and withdraw energy by operating the coils to generate magnetic fields that interact with the magnetic fields of the permanent magnets to produce induced current in the coils and directing the induced current to a power delivery location.

Abstract: A propeller system with directional thrust control comprising a hub, a plurality of blade attachment apparatuses attached to the hub, and a plurality of blades, each blade of the plurality of blades being attached to a blade attachment apparatus of the plurality of blade attachment apparatuses. The hub is operable to rotate about a rotation axis thereof. The plurality of blades is attached to the hub via the plurality of blade attachment apparatuses such that the plurality of blades rotates about the rotation axis of the hub when the hub rotates about the rotation axis thereof. Each blade attachment apparatus of the plurality of blade attachment apparatuses is operable to rotate the blade attached thereto about a blade rotation axis.
