Patent ID: 6989747

Claim:
A method for detecting unauthorized removal of electronic equipment that is connected to a power source, wherein a current delivered to the electronic equipment is sensed by a first current recognizing unit that is included in an arrangement, the arrangement is arranged between the power source and the electronic equipment, characterized therein that a check signal is sent to a sender unit when the current sensed by the first current recognizing unit is below a predetermined value, the sender unit receiving the check signal, the sender unit sending a bounce back signal to the electronic equipment, the bounce back signal being adapted to bounce back to the arrangement so that a detection of unauthorized removal is obtained and a generation of an alarm signal is triggered when the current sensed by the first current recognizing element is lower than the predetermined value and the bouncing back of the bounce back signal is not received by the sender unit, and a current delivered from the power source is sensed by a second current recognizing element that is included in the arrangement so that the signal is sent from the arrangement to the electronic equipment when a current sensed by the second current recognizing element is lower than a certain predetermined level.
