US 6,211,662 B1 · Hand-held hidden object sensor for sensing a location of objects hidden behind a surface of an architectural structure

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.

Dependent claims

A hand-held hidden object sensor for sensing a location of objects hidden behind a surface of an architectural structure, said sensor comprising:

an indicator for indicating a location of first and second object types hidden behind a surface;
sensing circuitry for sensing said first and second object types hidden behind said surface of said architectural structure;
an indication activation mechanism for causing the indication by said indicator of the location of said first object type as sensed by said sensing circuitry and precluding a concurrent indication of said second object type;
and a housing supporting said indicator, said sensing circuitry, and said indication activation mechanism.
