Abstract
A handheld device for manually scanning a body of water for the purpose of locating objects and persons therein. The present invention includes a waterproof housing with handle, a transducer, electrical and computer components within the housing for receiving and processing signals received from the transducer and a display to display the results of the processed signals. All located objects are displayed as symbols, providing a simple graphical representation of information indicating distance and location of any potential victims as well as other objects located within the area.
Claims20
A device for sensing the location of an object underwater, the device comprising:
- a waterproof housing with a handle;
- a data acquisition system attached to the waterproof housing;
- and
- a processor located within the waterproof housing, the processor comprising an amplitude and frequency controller.
A device for sensing the location of an object underwater, the device comprising:
- a waterproof housing with a handle;
- a transducer located within the waterproof housing, the transducer configured to convert electrical energy to acoustic energy, radiate sound pulse signals into the water along a field, and receive the returned sound pulse signals;
- a processor located within the waterproof housing, the processor comprising an amplitude and frequency controller;
- and
- a position correction system configured to normalize data affected by device tilt/rotation operation, to sense motion, and to discard non-material data allowing a change in motion to be about an axis of rotation up to 360 degrees along a field plane.
