Assignee: ONTECH SECURITY, S.L.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 7:
8. The device for measuring disruptions in a controlled magnetic field of claim 1 wherein the digital module comprises: (a) a communications module in series with the processor, including: (a.1) a clock input signal (SCK); (a.2) a serial output (SDO) to the processor; (a.3) a serial input (SDI) from the processor to the controlled magnetic field sensor; (a.4) a controlled magnetic field sensor selection signal; (b) a module of interruption signals comprising: (b.1) an interruption (INT_MES) indicating that a measurement has just been made and which is configurable to connect to a plurality of controlled magnetic field sensor in series; (b.2) an interruption (INT_LAST) indicating that the difference between the current and the last measurement has exceeded a configured threshold; (b.3) an interruption indicating that the difference between the current and the average of the last measurements has exceeded the threshold, given that the number of measurements to calculate the average is configurable; and (c) an electrode selection module configured as an 8-coded bits output signal that activates a switch which selects a measurement electrode, whereby each sensor is capable of being connected to one of the electrodes that would be configured as an emitter-receiver antenna of the controlled magnetic field.
