Abstract
Method and apparatus for a deactivator using an inductive charging technique are described.
Claims41
An apparatus, comprising:
- a power source;
- and
- a deactivation circuit connected to said power source, said deactivation circuit to inductively charge a deactivation antenna using said power source during a charge cycle, and generate a magnetic field having a deactivation envelope to deactivate a security tag during a deactivation cycle.
A system, comprising:
- a security tag;
- and
- a deactivator, said deactivator to include a power source connected to a deactivation circuit, said deactivation circuit to inductively charge a deactivation antenna using said power source during a charge cycle, and generate a magnetic field having a deactivation envelope to deactivate said security tag during a deactivation cycle.
A method, comprising:
- receiving a signal to deactivate a marker at a deactivator;
- charging a deactivation antenna from an power source during a charge cycle for said deactivator;
- and
- creating a deactivation field to deactivate said marker during a deactivation cycle for said deactivator, said deactivation field to generate a magnetic field having a deactivation envelope to deactivate said marker.
