摘要:
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.
摘要:
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.
