  • Publication number: 20140032017
    Abstract: Various types and levels of operator assistance are performed within a unified, configurable framework. A model of the device with a model of the environment and the current state of the device and the environment are used to iteratively generate a sequence of optimal device control inputs that, when applied to a model of the device, generate an optimal device trajectory through a constraint-bounded corridor or region within the state space. This optimal trajectory and the sequence of device control inputs that generates it is used to generate a threat assessment metric. An appropriate type and level of operator assistance is generated based on this threat assessment. Operator assistance modes include warnings, decision support, operator feedback, vehicle stability control, and autonomous or semi-autonomous hazard avoidance. The responses generated by each assistance mode are mutually consistent because they are generated using the same optimal trajectory.

    Abstract: The present invention applies model-based processing to a sensor output from a sensor such as a sonar, radar, or laser range finder. In particular, embodiments of the invention use a priori knowledge of a model signal return expected from a particular object to identify the location of the object relative to the sensor (and/or vice versa). In some embodiments the object is augmented with reflectors that return the sensor signal back towards the sensor so that the object can be more easily detected by the sensor. In preferred embodiments the reflectors are arranged in an a priori known pattern on the object, to help identify both the location and the orientation of the object with respect to the sensor. In the preferred embodiment, the sensor is a sonar, mounted on an unmanned underwater vehicle (UUV).

    Abstract: The system herein disclosed automatically detects whether an engine control unit instance number of a multi-engine marine vessel needs changing. Each engine control unit is electronically paired with a respective servo controller. A vessel controller is in communication with the servo controllers. The vessel controller commands in turn each servo controller to switch on its paired engine control unit, read the instance number of its paired engine control unit, switch off its paired engine control unit, and convey the instance number back to the vessel controller. The vessel controller then compares the instance numbers of the engine control units. If at least two instance numbers of the engine control units are duplicates of each other, the vessel controller ascertains that at least one of the instance numbers of the engine control units needs to be changed and assigns a new instance number to one of the engine control units.

    Abstract: An autonomous underwater vehicle (AUV) uses a model of propulsive efficiency to achieve high values of propulsive efficiency over a range of forward velocities, giving a lowered energy drain on the battery. Externally monitored information, such as that on flow velocity, is conveyed to an apparatus residing in the vehicle's control unit, which in turn signals the locomotive unit to adopt kinematics, such as fin frequency and amplitude, associated with optimal propulsion efficiency. In an embodiment, the model of propulsive efficiency is generated from a multilayer perception neural network model using data from aquatic species, such as undulatory fin propulsion in the knifefish (Xenomystus nigri), and a sensitivity analysis is used to lower the number of required inputs. Power savings could protract vehicle operational life and/or provide more power to other functions, such as communications.

  • Patent number: 8543256
    Abstract: According to typical practice of the present invention, a vehicle is remotely controlled and is travelable both in water and on land. The vehicle has two liquid-containment components that are situated generally one above the other. Pumping devices bring about transfer of cargo liquid (e.g., fuel or water) from either component to the other component. In accordance with the liquid transfer, the vehicle turns over, about its longitudinal axis, between two generally opposite buoyant positions, each of which is stable and viable for marine navigation. When the flow of the liquid sufficiently shifts weight from one component to the other, the vehicle inverts; that is, the emptying component flips from the bottom to the top, and the filling component flips from the top to the bottom. One of the buoyant positions of the vehicle is characterized by wheels for amphibiously transitioning the vehicle from water travel to land travel.

  • Patent number: 8543268
    Abstract: A method for determining the cumulative lateral slip of a towboat or combination barge tow/towboat. The method comprises providing two positional sensor instruments mounted at either end of a combination barge tow, each positional sensor capable of determining its geographical location from radio transmissions from, e.g., GPS satellites. The velocities of each positional sensor, both parallel and lateral (perpendicular) to the bearing of the barge tow, are determined. The cumulative sum of the absolute differences of the lateral velocities of the two positional sensors over time is calculated, stored and displayed by a microcomputer.

  • Patent number: 8536983
    Abstract: A method and system to optimize underwater operations utilizing a radio frequency identification (RFID) arrangement. The RFID arrangement includes a plurality of RFID tags positioned on an underwater surface, with each of the plurality of tags coded with unique information related to each tag's location on the underwater surface. The RFID system also includes an RFID reader/interrogator attached to an underwater explorer. When the underwater explorer is within a reading range of a tag, the reader/interrogator reads the unique tag information. The tag information is used to optimize underwater operations performed by the explorer, which may be a diver or a water vessel.
