Abstract
Abstract A circuit is included within electrical equipment to disable it in the event of its being tampered with. Typically, the circuit is arranged to sense an unauthorized action, such as movement of the equipment, or removal of its plug from the power point, to trigger an electronic lock which will prevent operation of an important part of the equipment, such as its power supply.
