Abstract: The present invention is directed towards a fixed positively buoyant manned submersible that includes a plurality of vertical thrusters and a sealed enclosure(s) that can support one or more human passengers. The vertical thrusters can include vertically aligned propellers that are coupled to motors that control the rotational velocity of the propellers. The vertical thrusters to generate a negative vertical thrust to allow the submersible to dive within a body of water. Horizontal movement can be achieved through horizontal thrusters or directing the thrust vectoring of the vertical thrusters.

Abstract: A system for communicating with a remotely operated underwater vehicle (ROV) includes a winged ROV coupled to a surface buoy by a tether. A controller on a support ship is coupled to the tether and the control signals are then transmitted through the tether to the ROV. Feedback and sensor signals are transmitted from the ROV through the wireless transceivers to the controller. The wings of the ROV produce negative lift which is greater than the buoyant force of the ROV and the vertical tension forces on the tether.

Abstract: A system for communicating with a remotely operated underwater vehicle (ROV) includes an ROV coupled to a surface buoy by a tether. A controller is coupled to a first wireless transceiver and a second wireless transceiver is attached to the surface buoy. Control signals are transmitted from the controller through the first wireless transceiver the second wireless transceiver on the surface buoy. The control signals are then transmitted through the tether to the ROV. Feedback and sensor signals are transmitted from the ROV through the wireless transceivers to the controller.
