Abstract: A slightly negatively buoyant personnel-accommodating chamber is suspended from a pair of buoyant-link flexible drive loops engaging the under surface of an ice cover over the body of water in which the chamber is submerged. Propulsion of the chamber can be effectuated through the medium of a power driven sprocket wheel arrangement that propels the chamber along the buoyant drive loops which in turn are caused to "roll" along the under surface of the ice.

Abstract: A mechanical propulsion system of a watercraft includes one or more propeller or impeller units operable to provide thrust for forward cruise. Disclosed herein is a non-mechanical marine propulsion system that utilizes heating-elements installed at submerged-regions of bow and stern of a waterborne watercraft in order to generate a pressure-difference between the bow and the stern by virtue of boiling and displacing surrounding water, and thus provide a net thrust to propel, steer or brake the watercraft. Further, a non-mechanical active roll stabilization system also based on the above concept is disclosed.

Abstract: An apparatus includes first and second tanks each configured to receive and store a refrigerant under pressure. The apparatus also includes at least one generator configured to receive flows of the refrigerant between the tanks and to generate electrical power based on the flows of the refrigerant. The apparatus further includes first and second hydraulic drives associated with the first and second tanks, respectively. Each hydraulic drive includes a first piston within the associated tank, a channel fluidly coupled to the associated tank and configured to contain hydraulic fluid, and a second piston within the channel and configured to move within the channel in order to vary an amount of the hydraulic fluid within the associated tank and vary a position of the first piston within the associated tank. The channel of each hydraulic drive has a cross-sectional area that is less than a cross-sectional area of the associated tank.

Abstract: An apparatus comprises multiple electrically conductive loops, an elongated tubular ferromagnetic shield, and an elongated tubular superconductive inner shield. The superconductive inner shield is positioned within the ferromagnetic shield. Each conductive loop includes (i) a thrust segment extending from a first end of the superconductive inner shield outside the ferromagnetic shield to a second end of the superconductive inner shield and (ii) a return segment passing through an interior passage of the superconductive inner shield from the second end of the superconductive inner shield to the first end of the superconductive inner shield. The conductive loops can be spatially arranged relative to a uniform external magnetic field so that interaction between the external magnetic field and electrical current flowing in the conductive loops results in asymmetric magnetic flux density around, and non-zero net force exerted on, the conductive loops.

Abstract: In one embodiment, a general-purpose wireless mobile device having a touch-sensitive screen and executing a remote control application is used to remotely control a vehicle (e.g., a marine vessel). The general-purpose wireless mobile device communicates via a wireless network with an interface (e.g., a server) that is coupled to an electronic control system of the vehicle (e.g., the vessel). In operation, environmental information and/or system status information is collected through the electronic control system, propagated to the interface (e.g., server), and then sent over the wireless network to the wireless mobile device. Similarly, control input is sent over the wireless network to the interface (e.g., server), which passes the information to the electronic control system, which in turn issues appropriate control signals to the vehicle subsystems (e.g., marine subsystems) to control the motion of the vehicle (e.g., the vessel).

Abstract: A system and method may include energizing one or more of a plurality of electromagnets contained within and fixedly distributed about a first region of a structure and de-energizing other of the electromagnets to attract a substance contained and movable within a second region of the structure to the energized electromagnets and change the center of gravity of the structure. The structure may be disposed on a surface or within a liquid, where energizing and de-energizing of the electromagnets causes the structure to move about the surface or within the liquid in a desired fashion. The substance may be a magnetic or magnetizable substance. Energizing and de-energizing the electromagnets may be performed by a controller responsive to a signal received from a sensor or transceiver.

Abstract: An electrokinetic actuator for a propulsion system is described. The actuator includes an array of channels, with each channel having an inlet and an outlet. A reservoir is included that contains an ionic solution of particles. A first electrode proximate to (or deposited at) the inlet and a second electrode proximate to (or deposited at) the outlet are connected to a voltage source. The voltage source and electrodes apply a voltage across the length of the channels to generate an electric field parallel to each channel. The electric field causes an electro-osmotic flow of ions from the reservoir to the outlet producing electrokinetic thrust at the outlet. By varying the concentration of the ionic solution and the magnitude of the electric field, the electro-osmotic flow of ions is controlled.
