Patent Application
20090189763
The present disclosure relates generally to a flexible security film and monitoring device that can detect and provide a real time alert, signaling the film has been tampered with or penetrated.
It is highly desirable to have an accurate method of determining and signaling exactly when tampering or penetration occurs. It is often difficult to accomplish this without triggering false alarms; items protected using current technology only tell you they were tampered with after they have been received and the tamper indicator has been inspected. They do not signal that they have been tampered with at the time of occurrence.
Security concerns exist for all types of packaging that contains high value items/goods, envelopes, crates, containers, or pallets that are shipped by carriers, air ship etc. All goods are susceptible to pilfering or tampering during transport or storage in unsecured areas.
To date there have been various attempts to provide monitoring and security. The use of dye when exposed to air changes color to let one know if someone has compromised the envelope or package. This provides a tamper indicator that has a small deterrent factor for honest employees.
However, these approaches do nothing for the user but to let the user know someone has tampered with the user's goods, which would be discovered upon opening the goods anyway.
Some of these approaches can result in a false trigger leaving the user with doubt in the carrier's ability to properly handle the package.
The present disclosure seeks to overcome the aforementioned drawbacks of the prior art proposal by utilizing a low cost RFID unit in concert with the film to send an instantaneous alert the moment tampering occurs. This greatly increases the chance of recovery and identifying the weak links in the system that plague the company with unnecessary loss at the high cost of loss of revenue and reputation. Additionally, the films unique properties are used with a communication link that can utilize a variety of RF technologies such as, but not limited to, passive and active RFID Tags and also use hard wired communications to name a few.
The present disclosure provides for a tamper indication film that is responsive to a variety of tampering methods. A tamper indicative film can provide an output as a visually or audibly perceptible display or as a feed to a data collection system such as a computer. It can provide a tamper indication that can be used on different sized envelopes and containers.
It can provide a tamper indication in remote areas using cellular or other communication links to provide remote security. Utilizing the security film which can be formed by way of illustrative but non-limiting example by a wall paper like material or tape, a user has the ability the provide low power to the tamper indicative device of the present disclosure, for example with an AA size lithium battery that could provide 24 hour security to the item it is attached to for ten years. Alternatively, a printable battery can be used. If the RFI Tags are passive the charge for the RFID Tag can be induced.
The tamper security device of the present disclosure that can be used for small packages is independent of other security systems such as those utilized for an office building or a house where the packaged item in question—the item for which the tamper security device is to be attached to—is located. Thus an authorized user may disable the home or office security to permit someone else to have access within the location where the item to be protected by the tamper security device is located but still have security control via the tamper security device over that particular item. This eliminates pilfering by limiting access to the personal item. Studies have shown that 90% of most thefts are opportunistic.
Additional objects, advantages and other novel features will be set forth in part of the description that follows and in part will become apparent to those skilled in the art upon examination of the following or maybe learned with practice of the present disclosure.
As described herein, there is a tamper indication device having a film attached and connected within the circuit that generates a signal in response to a tamper event. The signal is received by a micro-controller which generates an output signal to a display or data collection device and transceiver. The output signal can take information from a variety of different sensor types, i.e., shock, vibration, temperature and security breach information and display it in a data collection device.
Still other objects of the present disclosure will become apparent to those skilled in this and from the following description wherein there is shown and described in the preferred embodiment of this invention, simply by the way of illustration of one of the best modes contemplated for carrying out the present disclosure. As will be realized, the present disclosure is capable of different embodiments, and its several details are capable of modification in various, obvious aspects all without departing from the invention. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.
Reference will be made in detail to the present preferred embodiment(s) of the invention, an example of which is illustrated in the accompanying drawings
Referring now to the drawings in detail, wherein like numerals indicate the same elements throughout the views,

It is understood that the present disclosure is not limited to enclosures protected by the tamper indication device 1 of the present disclosure but can include any other item that one wishes to protect by providing the mechanism of the present disclosure for alerting someone when that item is being tampered with and also storing the tampering information within the transponder.
The film laminate 2 can be formed by printable conductive ink that can be printed on any surface including but not limited to Mylar film, plastic, flexible material, cloth etc. The ink would preferably have the following characteristics or attributes: a viscosity 12,000 CPS @30 C; a total solids content 61%; a density 17 lbs/gal; a flash point 212 F; VOC 794 grams of solvent/liter; an electrical resistance<0.015 ohms/square @1.0 Mil; and an electrical resistance<0.015 ohms/square @25.4 microns.
An embodiment of the present disclosure would be for palletized goods as shown in
There are numerous types of outputs possible with the open architecture designed into the system. It can easily be configured to provide audible alerts as well as silent alerts within microseconds of the unauthorized event/entry into
The tamper indication device 1 can be incorporated into a bullet proof vest acting as a sensor (not shown) for when a bullet penetrates the vest and sets off the security film by breaching it with the bullet's penetration therein. A police officer wearing a bullet proof vest may be able to have the vest stop the bullet from completely penetrating through his body; however, the officer still may suffer from trauma due to the impact from the bullet hitting the bullet proof vest and even knocking the officer over causing incapacitating injuries. If the police officer is working on a lone patrol, he may be hurt and unable to call for help due to the trauma suffered from bullet. Under these circumstances the tamper indication device of the present application works like a sensor not only detecting the bullet strike but also making it possible to determine the location of the bullet. This application of the tamper indication device of the present application works in the military as well as for providing a low cost bullet detection sensor.
Another embodiment is in the event an explosion or fire vision is often reduced to touch for both the evacuees and the rescuers. Exit signs during these emergencies just indicate a safe exit during the best circumstances. (No fire).
In the event you are in a multi floor building a fire or an explosion can make an exit unsafe and the closest exit may not be the best exit, but with no indication as it stands right now the wrong turn can be fatal.
The solution is to use the tamper indication device 1 as a sensor covering the floors, ceilings and the walls with its low power transceiver providing not only a security function, but also a wire frame of the interior of the building (not shown). With some logic you could turn the exit signs into smart exits indicating the best route to go and provide fire fighter-rescuers for the first time revolutionary near real time status of existing or remaining floors, walls and ceilings. The device can be incorporated into each corner of four corners of a building floor as wells as the ceiling and floor to detect breaches and alert someone as to where the breach is located specifically in the building.
While presently preferred embodiments have been described for purposes of the disclosure, numerous changes in the arrangement of method steps and apparatus parts can be made by those skilled in the art. Such changes are encompassed within the spirit of the invention as defined by the appended claims.
