Abstract: A person-portable object tracking system for identifying a location of a tracked person-portable object such as a security tracking bag, money pack or other container by a location identifier powered by a portable power source, the location transmitted to a central processor by a communicator. The location identifier preferably uses the global positioning satellite system or a radio frequency identification tag. An event detector sends a signal by way of the communicator to the central processor, the signal indicating the occurrence of a predetermined event such as a change from darkness to light, movement of a handle or the like and/or opening of an enclosure, cutting, motion and/or exceeding a distance from a desired location. Using plural event detectors in logical AND combination prevents unwanted event indications. The central processor archives a history of locations of the tracked person-portable object.

Abstract: A fire-resistant container such as a courier bag or the like which provides both active and passive protection to its contents to thereby obtain a high degree of fire protection over a long period of time. Passive protection is provided by insulating walls, while active protection is obtained by disposing inside the bag a gas cylinder containing a charge of halogenated hydrocarbon. The gas cylinder is closed with a solder plug whose melting temperature is chosen in accordance with the type of material to be protected.

Abstract: A door seal for use on an aircraft in which one portion of a striker (22) is attached to the door (12) and a second portion of the striker (34) is attached to the door frame (14) and in which one portion of a lip (18) for engaging the striker is attached to the door (12) and a second portion of the lip (16) is attached to the door frame (14), the two lip portions (16, 18) being configured to overlap one another and to mate with the two striker portions (22, 34) and with one another when the door (12) is closed, whereby the lip (18) on the door (12) transitions to a lip (16) on the door frame (14).
