Hand-Held Hidden Object Sensor For Sensing A Location Of Objects Hidden Behind A Surface Of An Architectural Structure
US Patent:
6211662, Apr 3, 2001
Filed:
Aug 7, 1998
Appl. No.:
9/130471
Inventors:

Assignee:
The Stanley Works - New Britain CT
International Classification:
G01R 1900
US Classification:
324 67
Abstract:
A hidden object sensor is described which senses and locates hidden objects hidden behind a surface of an architectural structure. The sensor includes sensing elements for sensing live wires behind the accessible surface, and separate sensing elements for respectively sensing metal and non-metallic objects behind the tested surface. A microprocessor alternates between the use of the various sensing elements and their associated circuits to detect live wires, metal objects, or wood studs. Visible and audible indicators are provided for indicating the device's mode of operation and the locations of sensed hidden objects. If a live wire is sensed, the processor may preclude an indication of a metal object or wood stud.
