This invention relates generally to anti-theft devices and in particular to a method for detecting unauthorized opening of containers and baggage.
Protecting personal property has become a major industry from a security system standpoint. Security systems today can be as elaborate as those installed to protect banking institutions, equipped with video cameras, hooked-up as alarms to the local police station and security guards, or be as simple as a car alarm that is sounded when the door is forced open.
Likewise, the shipping industry is faced with an increasingly growing security problem in that containers, packages, baggage, luggage and mail (all of which may be referred to as simply “shipping container” hereinafter) are vulnerable to being opened by unauthorized personnel, who might steal the contents. As this problem increases it becomes necessary to protect these articles in order to protect the customer's property.
Due to the smaller size and larger quantity of the shipping articles mentioned above, the protection system used must be compact for concealment purposes, and somewhat simple in operation, thereby making them easy to produce and install in mass quantities while being fairly easy to monitor and operate.
The anti-theft method of the present invention conveniently addresses all of these issues to provide a workable and fairly inexpensive solution to securing safe transportation of articles shipped in some type of enclosed shipping container.
The present invention introduces a method for protecting against the unauthorized opening of shipping containers which is disclosed in the several embodiments following.
A first embodiment comprises a simple trip-wire or magnetic circuit that provides continuity, which is detected electrically. Simply, if continuity is disabled by a forced entry of the container, electrical detection means, such as a radio-frequency-identification (RFID) transceiver tag (or simply RFID tag), will alert the owner or monitoring station. The trip-wire concept would require the replacing of a broken trip wire (resulting from forced entry), while the magnetic circuit concept can be reused repetitively.
A second embodiment comprises the magnetic circuit approach of the first embodiment by having the magnetic circuit and the detection device embedded into the shipping article during manufacturing. The preferred detection device, and RFID tag, could also be a battery backed transceiver type on which a replaceable or rechargeable battery could be mounted on the inside of the shipping container during manufacturing. The RFID tag would communicate with an interrogator unit, which could be connected to a host computer. The interrogator and/or the host computer would then monitor the shipping container's status (opened or closed). The RPID tag could also have an output that changes state upon alarm, so that another device could be connected to indicate the alarm via sound, flashing lights or other means.
Implementation of the present invention will become readily understandable to one skilled in the art in the detailed descriptions that follow.

In the next step, the rear battery epoxy is applied in station 20 before adding a stiffener and then folding the polymer base over onto the top cover as indicated in station 22. The epoxy material is then cured in station 24 before providing a final sealing step in stage 26 to complete the package as described in more detail below.

A pair of rectangular shaped batteries 38 and 40 are positioned as shown adjacent to the IC chip 32 and are also disposed on the upper surface of the base support member 30. The two rectangular batteries 38 and 40 are electrically connected in series to power the IC chip 32 in a manner more particularly described below. The device or package shown in

Next, a conductive epoxy is applied to the upper surfaces of the two batteries 38 and 40, and then the polymer base material 30 with the batteries thereon are folded over onto the cover member 42 to thus complete and seal the package in the configuration shown in

Both attaching methods serve as examples of how the opening detection unit may be attached to containers or doors that open. It would be preferred to have the wire attached so that it is not easily detected by casual observance and not easily broken by accident. Tag 67 could be affixed to label 66 with tag 67 itself being adhered to a self-adhesive paper, such as stamp, and then applied to the label.
A second embodiment of an “unauthorized opening detection device” is shown in

The methods of the embodiments discussed above, can easily be implemented into security systems. For example, by attaching the RFID tag and continuity completing circuitry to span between an entry/exit door and the framework supporting the door, unauthorized entry can now be monitored by activating the system when the door is to remain closed. Other such security schemes could also use the monitoring methods of the present invention.
It is to be understood that although the present invention has been described in several embodiments, various modifications known to those skilled in the art, such as applying these techniques to any kind of containers (mail, freight, etc.) or by various methods of attaching the detection device to the container, may be made without departing from the invention as recited in the several claims appended hereto.
