Abstract: Systems and methods for operating a marker. The methods comprise: storing energy collected by an energy harvesting element of the marker; using the stored energy to enable operations of the marker's communications element; receiving, by the marker's communications element, a marker deactivation signal transmitted from an external device; and causing either a resonator to be prevented from receiving transmit bursts emitted from an EAS system, a bias element's magnetic field to be normalized, or a resonator to be physically prevented from vibrating, in response to the marker deactivation signal's reception.

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.

Abstract: Systems and methods for making a marker. The methods comprise: disposing a resonator with a flat planar cross-sectional profile in a cavity formed in a first substrate partially defining a marker housing; sealing the cavity using a second substrate; placing a first bias element adjacent to the second substrate so that the resonator will be biased by the first bias element when the marker is in use to oscillate at a frequency of a received transmit burst; and using a physical structure in the cavity or a magnetic field passing through the cavity to reduce frictional forces between the resonator and at least the second substrate.

Abstract: Systems and methods for making a marker. The methods comprise: obtaining a marker housing having first and second cavities formed therein; disposing a first resonator in the first cavity and a second resonator in a second cavity; and placing a bias element at a location on or in the marker so that the first and second resonators are (a) equally spaced apart from the same bias element and (b) biased by the same bias element when the marker is in use to oscillate at a frequency of a received transmit burst.
