Abstract: Rotary positive displacement machines can include a rotor having a teardrop-shaped profile that undergoes planetary motion relative to a stator having an elliptical or near-elliptical profile. In some embodiments, these rotary positive displacement machines can be used for a variety of applications including as positive displacement pumps. In some embodiments the rotor and stator are helical. In some embodiments the rotor comprises a dynamic seal. Aspects of the machine geometry can be selected to provide operational and/or durability benefits.

Abstract: Techniques are disclosed for systems and methods to provide remote sensing imagery for mobile structures. A remote sensing imagery system includes a radar assembly mounted to a mobile structure and a coupled logic device. The radar assembly includes an imaging system coupled to or within the radar assembly and configured to provide image data associated with the radar assembly. The logic device is configured to receive radar returns corresponding to a detected target from the radar assembly and image data corresponding to the radar returns from the imaging system, and then generate radar image data based on the radar returns and the image data. Subsequent user input and/or the sensor data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Abstract: Flight based marine object search, detection and identification systems and related techniques include an unmanned aerial system (UAS) having a flight platform configured to execute a search path to search for an underwater object, an imaging system comprising image capture components configured to generate a stream of images corresponding to a field of view of the UAS, and a logic device associated with the UAS and configured to analyze the stream of images using a marine video analysis (MVA) system to detect a region of interest comprising an underwater object, identify an underwater object in the detected region of interest, and notify a mobile structure of the identified object.

Abstract: Flight based infrared imaging systems and related techniques, and in particular unmanned aerial system (UAS) based systems, are provided for aiding in operation and/or piloting of a mobile structure. Such systems and techniques may include determining environmental conditions around the mobile structure with the UAS detecting the presence of objects and/or persons around the mobile structure and/or determining the presence of other structures around the mobile structure. Instructions for the operation of such mobile structures may then be accordingly determined responsive to such data.

Abstract: Improved solids handling in rotary positive displacement machines, where the machines are based on trochoidal geometry, can be achieved through the use of solids-handling features on the surface of the rotor and/or stator and/or by the use of modified seals mounted on the rotor or stator. In at least some embodiments the rotary machines comprise a helical rotor that undergoes planetary motion relative to a helical stator.

Abstract: Techniques are disclosed for systems and methods to provide wildlife feeding flock detection using a remote sensing imagery system. A remote sensing imagery system includes a radar assembly mounted to a mobile structure and a coupled logic device. The logic device is configured to receive radar returns corresponding to a detected target, determine a radial velocity spectrum associated with the detected target based, at least in part, on the received radar returns, and determine a probability the detected target includes a feeding flock based, at least in part, on the determined radial velocity spectrum. The logic device may generate radar image data based on the received radar returns, the determined radial velocity spectrum, and/or the probability the detected target includes the feeding flock. Subsequent user input and/or the sensor data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Abstract: Techniques are disclosed for systems and methods to provide three dimensional volume rendering of volume data for use when operating mobile structures. A three dimensional volume rendering system includes a logic device configured to communicate with a user interface and receive volume data from a volume data source. The logic device is configured to render a three dimensional) representation of the volume data on a display of the user interface according to a view perspective, render an indicator key on a first two dimensional plane overlaid in the 3D representation, detect a change condition, and rotate the indicator key about a rotational axis in response to the detected change condition.

Abstract: Techniques are disclosed for systems and methods to provide casting guidance for users of mobile structures, including watercraft. A casting guidance system includes a sonar transducer assembly and a logic device configured to communicate with the sonar transducer assembly. The sonar transducer assembly is adapted to be mounted to a mobile structure and placed in a body of water. The logic device is configured to identify one or more underwater targets in sonar data received from the sonar transducer assembly, determine casting guidance parameters corresponding to the one or more identified underwater targets, and generate at least one casting guidance identifier based, at least in part, on the determined casting guidance parameters. Subsequent user input, the sonar data, and/or the casting guidance parameters may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.
