Abstract:
An apparatus for protecting an entrance to a protected area comprises a magnetic sensor to measure an ambient magnetic field or gradient within a first zone of sensitivity at a non-magnetic sensor means adapted to detect the presence of objects within a primary detection zone, a signal processing circuit arranged in communication with the magnetic sensor apparatus and nonmagnetic sensor apparatus, and a warning device operable by an output signal from the signal processing circuit, the warning device adapted to provide an alarm. The signal processing circuit identifies temporal variations due to the movement of a ferromagnetic object within the ambient magnetic field and correlates them with instances in which the non-magnetic sensor means detects the presence of an object in its detection zone, and causes the alarm to operate in the event that the correlation is indicative of the presence of a ferromagnetic object in the primary detection zone. It also determines the direction from which an object is approaching the using signals from the nonmagnetic sensor means and modifies the operation of the warning device dependent on the direction.

Claim (Index 5):
Apparatus according to  claim 3  in which the modification comprises modifying the threshold at which an alarm is triggered as a function of the magnitude of the temporal variations in magnetic field detected by the magnetic sensor when a known RFID tag is detected.
