  • THEFT PREVENTION SYSTEM FOR A PORTABLE ELECTRIC APPARATUS
    Publication number: 20100271206
    Abstract: A theft protection system for an electrical appliance is connected between an electrical appliance, such as a laptop computer, and a voltage source. The theft protection system regularly measures the charging current that is carried between the electrical appliance and the voltage source. If this charging current drops below a predetermined minimum value, a limit value, the theft protection system delivers an alarm signal via an alarm means. The limit value can be set by means of an incorporated calibration unit. The calibration is initiated by pressing the set button.
