Apparatus and methods for detecting concealed personal security threats may comprise conventional mirrors and less conventional arrays of Hall-effect sensors and/or magnetometers, preferably at least two axis or three axis sensors or sensors mounted back-to-back. The concealed personal security threats may comprise, for example, sticky devices consisting of geographic position sensors for covertly broadcasting motor vehicle location data, of so-called Improvised Explosive Devices (IED's) which may be covertly or openly affixed to, for example, the undercarriages of motor vehicles using strong magnets and later exploded, the former giving away private location information, the latter causing damage to the motor vehicles to which they are affixed and sticky containers for hiding contraband among other “sticky devices.” Magnetic fields detected by, for example, arrays of Hall-effect sensors and the like may be quantified and stored in processor memory as a vehicle magnetic field signature. A processor receiving magnetic field data collected by the arrays may retrieve and subtract known signatures from acquired magnetic field data for a given vehicle to obtain location for a magnetic field on the vehicle that may be of potential interest as a risk and.
A magnetic field sensor for detecting a magnetic field of a sticky device configured to adhere to a portion of a vehicle, the magnetic field sensor comprising:
A magnetic field sensor for detecting a magnetic field of a sticky device configured to be attached to a vehicle, the magnetic field sensor comprising:
A magnetic field sensing and scanning device comprising a plurality of pairs of Hall-effect sensor circuits mounted back to back to identify either of two polarities of a suspect magnetic field, the Hall-effect sensor circuit pairs being mounted spatially distant from one another on a surface of the scanning device, the Hall-effect sensor pairs having a corresponding light emitting diode display whereby the location of the Hall-effect sensor pairs corresponds to the location of the light emitting diodes of the display.
