  • Patent number: 5142502
    Abstract: A microcomputer-based side scanning sonar system is provided. The system uses a personal microcomputer with a custom designed control and data collection circuit card to provide integrated sonar and navigational data to a display. A specialized software program allows navigational data to be collected from any standard navigational device compatible with NMEA 0183 standards and integrated with sonar data. The system allows accurate and repeatable navigation to sonar targets, including return to the target.

  • Patent number: 5142503
    Abstract: A side-scanning sonar towfish constructed from a solid polyvinyl chloride (PVC) rod is provided. The PVC rod is milled and slotted to provide recesses for electronics and transducers and slotted to provide attachment points for fins and tow rail. The entire fish is then filled and sealed with urethane thereby providing sealed solid unit. A special multi-layer acoustic matching system is bonded over the transducers to provide maximum coupling efficiency of the acoustic signal thereby allowing operation of the fish at reduced power requirements.

  • Patent number: 4285010
    Abstract: In order to obviate the necessity for providing a complete channel of electronics for each transducer of an array incorporated into a real-time ultrasonic imaging system, all system transducers are disposed in apparent series with a single inductor as to direct current. Charging resistors permit each transducer to slowly capacitively charge to a predetermined voltage under static conditions. When a switching transistor disposed in series with a given transducer is placed in the conducting state, the transducer rapidly discharges and mechanically deflects to introduce an ultrasonic pulse into an object. While the switching transistor remains conductive, the inductor and transducer are in parallel circuit as to echo signals returning to the transducer. When the switching transistor is rendered non-conductive, the transducer again charges capacitively in anticipation of a succeeding cycle.
