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 move­ ment of the equipment, or removal of its plug from the power point, to trigger an electronic lock which will prevent opera­ tion of an important part of the equipment, such as its power supply.
