A Method and a Device for Detecting Intrusion Into or Tampering with Contents of an Enclosure
First Claim
1. A method for detecting intrusion into or tampering with contents of an enclosure, characterised byproviding at least one gas proof seal-barrier in association with the enclosure,producing a first environment within said gas proof seal-barrier,said first environment being different regarding at least one characteristic feature from a second environment surrounding said gas proof seal-barrier,arranging at least one detector within said gas proof seal-barrier for detecting a predetermined change of the characteristic feature of the said first environment,transferring irrevocably said detector from a first state to a second state when there is a predetermined change of the characteristic feature, andsupplying the state of the detector to a position outside said gas proof seal-barrier.

Abstract
A method and a device for detecting intrusion into or tampering with contents of an enclosure. According to the method at least one gas proof seal-barrier is provided in association with the enclosure and a first environment is produced within said gas proof seal-barrier. Said first environment is different regarding at least one characteristic feature from a second environment surrounding said gas proof seal-barrier. At least one detector is arranged within said gas proof seal-barrier for detecting a predetermined change of the characteristic feature of the said first environment. Said detector is transferred irrevocably from a first state to a second state when there is a predetermined change of the characteristic feature, and the state of the detector is supplied to a position outside said gas proof seal-barrier.

22. A device for detecting intrusion into or tampering with contents of an enclosure, characterised in
that the enclosure is provided with at least one gas proof seal-barrier enclosing an environment, said first environment being different regarding at least one characteristic feature from a second environment surrounding said gas proof seal-barrier, that at least one detector is provided within said gas proof seal-barrier that the detector is arranged to switch from a first state to a second state when there is a predetermined change of the characteristic feature of the said first environment, and that the detector is provided with means for supplying the state to a location outside the gas proof seal-barrier.
