  • Process for detecting metallic items including a search path defined by a linear movement with a superimposed rotational movement along a curved closed path
    Patent number: 5719500
    Abstract: A process for detecting metallic or other electrically conducting objects in essentially flat search areas by means of at least one search probe which generates search signals is presented. The probe is guided relative to the search area parallel to its surface, along a search path situated in a search surface. By at least one analysis unit coupled with the search probe, the search signals are automatically correlated with the positions of the search probe on the search surface, as determined by localizing devices. The correlated data are converted to an image of the objects in the search area, such as an object map.
