Embodiments of the present invention provide an electromagnetic sensor () for detecting a microstructure of a metal target, comprising: a magnetic device () for providing an excitation magnetic field; a magnetometer () for detecting a resultant magnetic field induced in a metal target; and a calibration circuit () for generating a calibration magnetic field for calibrating the electromagnetic sensor, wherein the calibration reference magnetic field is generated by an electrical current induced in the calibration circuit by the excitation magnetic field.

Sensors

A detection system comprising a plurality of magnetic field generators and a plurality of magnetic field detectors located adjacent to a detection area, and a control system arranged to generate magnetic field using the generators, and, for each of the generators, to make measurements of the magnetic field generated using each of the detectors, and processing means arranged to process the measurements to generate a data set characterising the detection area.

Detector systems

An ultra-wide band microwave based personnel/passenger screening system, and in particular, a system for material specific detection, uses non-ionizing radiation in which focused beams of low intensity microwave radiation are projected in rapid succession at an individual as they walk through a portal.

Ultra wide band detectors

A detection system comprising a plurality of magnetic field generators and a plurality of magnetic field detectors located adjacent to a detection area, and a control system arranged to generate magnetic field using the generators, and, for each of the generators, to make measurements of the magnetic field generated using each of the detectors, and processing means arranged to process the measurements to generate a data set characterizing the detection area.

The present application is a detection system for locating and characterizing an object placed in a detection area in a three dimensional space. The detection system includes a plurality of magnetic field generators and magnetic field detectors arranged on opposite sides of the detection area and a control system for enabling generation of a magnetic field in the detection area by the magnetic field generators and for measuring of the magnetic field modified by the object at each of the magnetic field detectors. The detection system also includes a processor for processing the measured magnetic field to obtain a data set characterizing the object and a location of the object. The processor applies a reconstruction process on a predefined number of measurements of the modified magnetic field.

Apparatuses and methods for analyzing at least one characteristic of a test signal coupled out from one of a plurality of cable lines by a coupling unit to determine whether that test signal has propagated directly to the coupling unit via a single cable line or has propagated indirectly to the coupling unit via one or more coupling paths between different cable lines. The determination of whether the test signal has propagated directly to the coupling unit via a single cable line or has propagated indirectly to the coupling unit via one or more coupling paths between different cable lines, may advantageously be used for operational or diagnostic purposes, e.g. to identify interconnections between ports in a network.

An apparatus for identifying interconnections in a network. The apparatus comprises a plurality of transmitter coupling units, a plurality of receiver coupling units, and an interconnection identification means configured to identify interconnections between the transmitter coupling units and the receiver coupling units by cable lines in the network. In some embodiments, the interconnection identification means is configured to, if any one of the transmitter coupling units is coupled to the same cable line as a selected one of the receiver coupling units, identify the interconnection between the transmitter coupling unit and the selected receiver coupling unit according to by a binary tree search algorithm.

Apparatuses and methods for coupling a signal to and from a twisted pair cable by non-contact coupling with twisted pairs in the twisted pair cable, such that the signal propagates along the cable between at least two of the twisted pairs. In particular, a coupling unit for coupling a voltage signal to and/or from such a cable, the coupling unit having a first electrode and a second electrode.

Apparatuses and methods for coupling a signal to and/or from a cable

A method of determining the state of a cable including at least one electrical conductor, uses a generated test signal and applies it to at least one conductor by a non-contact coupling transmitter. The resulting signal is propagated along the at least one conductor and a non-contact electrical coupling receiver picks up a reflected signal, and compares the reflected signal to expected state signal values for the cable to determine its current state.
