US Patent or Application No. Titled Issue Date
7,145,835 Personal Sonar Device December 5, 2006
7,272,075 Personal Sonar Device September 18, 2007
11/901,496 Personal Sonar Device Est. September 2008

The basic concept with all of the patents is a sonar device that transmits a sonar signal and receives a reflected signal from underwater objects. The sonar system filters the ambient noise signals in the water from the reflected sonar signals. The filtered sonar signals are then compared to a database of fish. If a detected sonar signal corresponds to a signal stored in the database of fish, the system will emit a signal. Based upon the reflected and filtered sonar signals, the system can detect different types of fish that are in the database of fish.

US Patent No. 7,145,835 is directed towards a system that detects hazardous fish such as sharks, orca, etc. When a hazardous fish is detected the inventive system actuates an output device. The specific output device is not described in the claims but it can be any type of signal to the user of the personal sonar device such as a warning light or audible alarm. The user can respond to the warning by moving away from the hazardous fish and warning others in the area. The device can be mounted in various objects including a waterproof housing, surfboard or a hull of a boat.

US Patent No. 7,272,075 is similar to US Patent No. 7,145,835 but removes the limitation that the system only detects hazardous fish. Thus, this personal sonar system will actuate an output device when any fish stored in the fish database is detected. This can be particularly useful for fishermen trying to catch specific types of fish because the patented device can identify different types of fish that are within the range of the inventive sonar device. The device can be mounted in a waterproof housing or a hull of a boat.

US Patent Application No. 11/901,496 is directed towards a system that transmits a first signal indicating the detection of the fish and a second signal indicating the GPS location of the inventive sonar device. This can be useful for manually or automatically monitoring an area of water. The inventive devices can be placed throughout an area of interest. The inventive devices can be coupled to objects such as buoys and secured to fixed or movable locations such as a boat hulls. If a known type of fish is detected, the system will transmit a signal to notify a user that a specific type of fish has been detected at a specific GPS location. For example, the type of system can be used as an automated shark detection system used to protect beaches or areas of water used by people or an indicator of good fishing conditions. The system can be powered by solar panels.
