Security system for portable device with arming feature
First Claim
1. A security system for a portable device, the security system comprising:
- a first sensor that is capable of being operatively attached to a portable device,the first sensor having a secured state and an unsecured state;
a controller that is capable of sensing the state of the first sensor; and
an alarm signal generator,the security system having an armed state and an unarmed state,the controller capable of detecting that the first sensor, 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 signed to be generated,the controller and first sensor configured so that with the security system in the unarmed state and the first sensor changed from the secured state into the unsecured state;
a) the security system can be changed from the unarmed state into the armed 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.

Abstract
A security system and method of monitoring a portable device. The security system has a first sensor, a controller, and an alarm signal generator. The controller is capable of detecting that the first sensor, with the security system in an armed state, has changed from the secured state, and as an incident thereof, causing a signal to be generated by the alarm signal generator. The controller and first sensor are configured so that under certain conditions 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 produce a detectable signal in the event of a security breach.

-
a first sensor that is capable of being operatively attached to a portable device, the first sensor having a secured state and an unsecured state; a controller that is capable of sensing the state of the first sensor; and an alarm signal generator, the security system having an armed state and an unarmed state, the controller capable of detecting that the first sensor, 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 signed to be generated, the controller and first sensor configured so that with the security system in the unarmed state and the first sensor changed from the secured state into the unsecured state;
a) the security system can be changed from the unarmed state into the armed 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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A method of monitoring a portable device, the method comprising the steps of:
-
providing a security system having armed and unarmed states and comprising; a) a first sensor with secured and unsecured states; b) a controller that is capable of sensing the state of the first sensor; and c) an alarm signal generator; operatively attaching the first sensor to the portable device; and changing the first sensor from the unsecured state into the secured state to allow the controller, with the security system in the armed state, to interact with the first sensor to cause the alarm signal generator to cause a detectable signal to be generated in the event that the first sensor is thereafter changed back into the unsecured state, only after the first sensor is maintained in the secured state for a predetermined time period. - View Dependent Claims (15, 16, 17, 19, 20)

18. The step of changing the first sensor from the unsecured state into the secured state comprises changing the first sensor from the unsecured state into the secured state only after the first sensor is maintained in the secured state for a predetermined time period of on the order of 2 minutes.
