20080264323 | Submersible Vehicle - A submersible vehicle having an outer hull which defines a hull axis and appears substantially annular when viewed along the hull axis, the interior of the annulus defining a duct which is open at both ends so that when the vehicle is submerged in a liquid, the liquid floods the duct. The vehicle further comprising means for rolling the vehicle about the hull axis. A buoyancy control system may be provided, and the outer hull may be swept with respect to the hull axis. Various methods of deploying and using the vehicle are described. | 10-30-2008 |
20100044496 | ANNULAR AIRBORNE VEHICLE - An airborne vehicle having a wing-body which defines a wing-body axis and appears substantially annular when viewed along the wing-body axis, the interior of the annulus defining a duct which is open at both ends. A propulsion system is provided comprising one or more pairs of propulsion devices, each pair comprising a first propulsion device mounted to the wing-body and positioned on a first side of a plane including the wing-body axis, and a second propulsion device mounted to the wing-body and positioned on a second side of the plane including the wing-body axis. A direction of thrust of the first propulsion device can be adjusted independently of the direction of thrust of the second propulsion device and/or a magnitude of thrust of the first propulsion device can be adjusted independently of the magnitude of thrust of the second propulsion device. In certain embodiments the wing-body appears swept forward when viewed from a first viewing angle, and swept backward when viewed from a second viewing position at right angles to the first viewing angle. | 02-25-2010 |

20140292592 | ANNULAR VEHICLE WITH DIPOLE ANTENNA - An annular vehicle having a body which defines a body axis and appears substantially annular when viewed along the body axis. The interior of the annulus defines a duct which is open at both ends. The vehicle includes an electric field (EF) coupled dipole antenna arrangement for electro-magnetic communications, which includes at least one dipole antenna. The vehicle is used as a node in an underwater communications system for communicating with other node(s) using their EF coupled dipole antenna arrangements. The electric field coupled dipole antenna arrangement can provide communications with lower latency than systems employing acoustic communications. The annular body provides good separation for electrodes of the EF coupled dipole antenna arrangement disposed around the body. | 10-02-2014 |
20150019053 | COMMUNICATION WITH AN UNDERWATER VEHICLE - A method of communicating with an underwater vehicle comprising a propulsion system for propelling the vehicle through the water. A series of data sets are encoded and transmitted to the underwater vehicle in a series of signal bursts, and decoded at the underwater vehicle. The propulsion system is operated in a series of thrust pulses separated by drift periods such that the propulsion system operates at a relatively high rate during the thrust pulses and at a relatively low (or zero) rate during the drift periods. The drift periods are timed such that each signal burst arrives at the underwater vehicle during a drift period and not during a thrust pulse. The method may be performed with a single vehicle or a plurality of underwater vehicles. The encoded data signals are broadcast simultaneously to the underwater vehicles in the series of signal bursts. | 01-15-2015 |
