Abstract
Systems and methods for operating a marker. The method comprising: receiving, by a communications element of the marker, a marker deactivation signal from an external device; and causing a coil surrounding at least the marker's resonator to be shorted in response to the marker deactivation signal, by supplying power to a deactivation element so that the deactivation element switches from an open state to a closed state. In some scenarios, the power is supplied by an energy harvesting element disposed in the marker.
