  • Patent number: 9182486
    Abstract: Sonar rendering systems and methods are described herein. One example is an apparatus that includes a transducer element, position sensing circuitry, processing circuitry, and a display device. The processing circuitry may be configured to receive raw sonar data and positioning data, convert the raw sonar data into range cell data based at least on amplitudes of the return echoes, make a location-based association between the raw sonar data and the positioning data, plot the range cell data based on respective positions derived from the positioning data and rotate the range cell data based on a direction of movement of the watercraft to generate adjusted range cell data. The processing circuitry may be further configured to convert the adjusted range cell data into sonar image data, and cause the display device to render the sonar image data with a presentation of a geographic map.

  • Patent number: 9135731
    Abstract: Devices and systems for noninvasively and nondestructively sensing a signal in an electrical outdoor device, such a fishing transponder, are described. The device can include a first electrical connection to connect to a port on a main unit of an echo-location device, a second electrical connection to connect to a port on a transponder, the second electrical connection being in bi-directional electrical communication with the first connection to send a power signal from the main unit to the transponder and return an echoed signal to the main unit, and a third electrical connection to sense the signals between the first electrical connection and the second electrical connection. Positioning data is also created and stored with the signal data. The positioning data can be used to control acquisition of data. Systems and methods for processing the sensed data are described. Reports can be generated using the data and, in some reports with the positioning data.

    Abstract: A sonar transducer assembly for mounting to a surface watercraft includes a rectangular first transducer configured to produce a first beam defining a fan-shape and extending generally in a first plane. The assembly further includes a rectangular second transducer configured to produce a second beam defining a fan-shape and extending generally in a second plane. The first transducer and the second transducer are oriented such that the respective first and second beams insonify different first and second areas each extending laterally with respect to a running direction of the surface watercraft, and such that the first beam is outside of the second plane of the second beam, the resulting planar separation of the first and second planes of the first and second beams reducing interference between the first and second transducers.
