AT A GLANCE
Developed at the Fraunhofer Institute for Integrated Circuits IIS, IndLoc positioning technology is an economical solution for the three-dimensional, real-time positioning of passive objects in a defined space with a high degree of precision. To this end, a live conductor encloses a defined area of variable size and generates a weak alternating magnetic field within the perimeter. The object to be positioned carries a small, passive coil, similar to an RFID transponder.
This “positioning coil” generates a secondary magnetic field in the monitored space, which is detected by antennas and analyzed by the IndLoc system. In this way, it is possible to detect a boundary breach – as well as the position, orientation, and motion of the target object – with a high degree of accuracy and without the need for active electronics. Using suitable back-end software, the captured positional data can be visualized, processed, or assigned to specific patterns. Predefined actions such as alarm notifications can be triggered in the event of boundary breaches, for example.
