Memory (120) in a device (100) that includes a power source (105) is erased when an alarm triggering event is detected. An alarm signal is provided that is used to determine whether the memory (120) has been erased since a transition from normal to low power mode. It is only when the memory (120) has not been erased since such a transition, that the memory (120) is erased, thereby providing an energy efficient erasure process.

A system for rapidly detecting power disturbances with ferroresonant transformers having a decay profile comprising the steps of rectifying a power signal; comparing the rectified signal against a reference signal; comparing the rectified signal against a dynamic reference signal; and generating a power-fail signal in response to either comparison falling below its respective reference.
