US Patent:

7457196, Nov 25, 2008

Filed:

Jul 17, 2006

Appl. No.:

11/458011

Inventors:

Timothy W. Acker - Arlington WA, US
Assad E. K. Ebrahim - Bellevue WA, US
James J. Dawson - Edmonds WA, US

Assignee:

Biosonics, Inc. - Seattle WA

International Classification:

G01S 15/89

US Classification:

367 88

Abstract:

A sonar transducer network for observing a seabed includes a controller. A first transducer assembly includes a first acoustic transducer to convert a first ping to a first electrical signal; and a first transducer processor to receive a first electrical signal from the first acoustic transducer to generate the first transducer data. At least one second transducer assembly is spaced apart from the first transducer assembly. The second transducer assembly includes a second acoustic transducer to convert a second ping to a second electrical signal. The second transducer processor receives the second electrical signal from the second acoustical transducer to generate second transducer data. A network bus communicates first transducer data and second transducer data with the controller.
