An inspection system positions a balancing shim to asymmetrically balance a magnetic field generated by an inductive sensor, which forms part of the inspection system. Additionally, relays and capacitors used to tune the inductive sensor to a desired resonance frequency are geometrically arranged to minimize electrical interference generated by operation of the relays and capacitors. A shielding device, which may be formed on a printed circuit board, protects a magnetic field generated by the inductive sensor from external electromagnetic interference. A slot positioned in the inductive sensor may be used to tune a resonant mode of the inductive sensor to accurately and particularly detect metallic shanks and/or other metallic objects in shoes, socks, and/or clothing.

Apparatus and method for non-symmetric magnetic field balancing in an inspection scanner

A method of operating a passenger screening kiosk system to perform at least one verify a passenger's identity, detect the presence of an explosive material, and detect the presence of a metallic material includes initiating a prompt to be issued by the passenger screening kiosk system to prompt the passenger to enter the passenger screening kiosk system, prompting the passenger to enter the passenger screening kiosk system, and determining whether the passenger is within the passenger screening kiosk system.

Passenger screening system and method

A screening system including a first modality comprising at least one inductive sensor, and a second modality including at least one metal detection coil configured to generate a magnetic field, said induction sensor configured to detect a change in the magnetic field generated by the metal detection coil.
