Patent ID: 7880605

Claim:
A security system for a portable device, the security system comprising: a plurality of sensors each capable of being operatively attached to a portable device, the sensors each having a secured state and an unsecured state; a controller that is capable of sensing the state of the sensors; and an alarm signal generator, the security system having an armed state and an unarmed state, the controller capable of detecting that each of the sensors, with the security system in the armed state, has changed from the secured state into the unsecured state and, as an incident thereof, causing the alarm signal generator to cause a detectable signal to be generated, the controller and sensors configured so that with the security system in the unarmed state with one of the sensors in the plurality of sensors in the secured state and a first sensor in the plurality of sensors separate from the one sensor in the unsecured state: a) the security system can be changed from the unarmed state into the armed state with the one sensor in the secured state after which the first sensor can be changed from the unsecured state into the secured state whereupon the controller will detect changing of the first sensor from the secured state into the unsecured state and cause the alarm signal generator to cause a detectable signal to be generated; and b) the first sensor must be changed from the unsecured state into the secured state and maintained in the secured state for a predetermined time period before the controller, first sensor and alarm signal generator can thereafter interact to cause the alarm signal generator to cause a detectable signal to be generated in the event that the first sensor is changed from the secured state into the unsecured state with the security system in the armed state.
