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 orientation and position sensor (OPS) coupled to or within the radar assembly and configured to provide orientation and position 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 orientation and/or position data corresponding to the radar returns from the OPS, determine a target radial speed corresponding to the detected target, and then generate remote sensor image data based on the remote sensor returns and the target radial speed. 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 reliable and relatively quick bottom reacquisition in sonar systems for mobile structures, including three dimensional (3D) capable and/or multichannel sonar systems. A sonar system includes a sonar transducer and associated processing and control electronics and optionally orientation and/or position sensors disposed substantially within the housing of a sonar transducer assembly. A logic device of the sonar system is configured to detect bottom lock loss based, at least in part, on sonar data provided by the sonar transducer, determine an expected bottom depth associated with the detected bottom lock loss, and generate updated sonar data based, at least in part, on the expected bottom depth. Resulting sonar data and/or imagery may be displayed to a user and/or 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 dynamic threshold sonar systems for mobile structures. A dynamic threshold sonar system may include sonar equipment configured to capturing sonar data by receiving and converting acoustic returns into arrays of time differentiated sonar data samples, and a processor communicatively coupled to the sonar receiver. The processor may be configured to receive the sonar data samples and determine noise characteristics of the sonar data. The processor may determine a threshold for surface detection based on the noise characteristics and detect a surface, and determine a distance to the surface, based on a comparison of the sonar data to the threshold that has been determined based on the same sonar data.

A sonar system includes a sonar transducer assembly including a sonar transducer, a sonar receiver configured to receive acoustic returns from the sonar transducer and convert the acoustic returns into arrays of time differentiated sonar data samples, and a logic device adapted to communicate with the sonar receiver. The logic device is configured to receive the arrays of the time differentiated sonar data samples from the sonar receiver and process the received arrays to enhance the time differentiated sonar data samples substantially without enhancing sonar artifacts in the time differentiated sonar data samples Processed sonar data and/or resulting imagery may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the sonar transducer assembly and/or a mobile structure.

Abstract: A cable holder useful for holding a single insulated cable assembly or a multiplicity of insulated cable assemblies wherein the cable holder is formed by a pair of components attached to or integral with each other so as to form a sheath or sleeve for containing the cable assembly or cable assemblies. Adjacent metal ends of the adjoining cable parts are interconnected by a metal joint.
