Zusammenfassung:An electronic lock includes a rotatable core movable within an outer body. The rotatable core includes a piezo-electric actuator configured to move a tumbler blocking member into or out of interfering engagement with one or more tumblers. Tamper circuitry coupled with the piezo-electric actuator is configured to resist an externally induced acceleration of the electronic lock by shunting electrical power produced by an externally induced motion of the piezo-electric actuator back to the piezo-electric actuator.
