Abstract
The invention is a secure container for the transport and storage of materials that can alert the user as to the location and condition of materials, as well as container status. This provides cargo and access information that is critical in high-value or controlled shipments. The container uses a wound fiber-optic layer embedded in a covering. A transmitted light signal is sent through the fiber-optic layer to a receiver. Any change in the light signal causes an alarm or indication. The container also gives real time read outs, remotely or locally, as to the conditions of the contents and the container itself.
Description




FIELD OF INVENTION




The present invention relates generally to a secure container that can be used for the transport and storage of materials whose location and condition needs to be continuously monitored or recorded.




BACKGROUND OF THE INVENTION




In today's world of commerce, materials are constantly moving interstate and internationally. Many of these materials need to be either controlled or monitored. It is useful to those that are burdened with the responsibility to control or monitor these shipments to have real-time information about the status and location of the materials, and the containers that house those materials. For example, it is useful to know the location, the condition, and if the cargo was accessed or tampered with by unauthorized parties. These materials and cargo can include things such as: high value items, jewels and cash; weapons, strategic or conventional; hazardous materials; medical or biological related; and materials that are time or condition sensitive in nature. A variety of means are now employed to attempt this level of control and monitoring.




The oldest of the means is to place the cargo under lock and key at the shipping point, and then later unlock the cargo at the point of delivery. This method has limited commercial success as it does not provide information as to either the condition of the cargo during shipment, or if the cargo was taken on a detour. Nor is any indication given if a duplicate key was used to gain access to the cargo during transit, and then reseal the shipping container to conceal that access.




A global positioning system (G.P.S.) is a partial solution for this problem. G.P.S. has been used for things like automobiles and other high value items. However, this does not provide information on access or condition during shipment. For example, the G.P.S. could be tracking a tow truck moving the automobile after an accident and the G.P.S. would simply provide information on its continuously changing location.




Current burglar alarm technology utilizes continuous conductive strips on windows and doors. However, these strips, like any conductive strips, may be jumpered around, and therefore defeated.




In view of these difficulties, it would be useful to those charged with the responsibility for the shipment of critical cargo to know the cargo's condition, if it was accessed or tampered with, as well as its location continuously. This is possible with the instant invention.




SUMMARY OF THE INVENTION




The instant invention simultaneously provides, location, access, and condition information about the cargo and containers of critical shipments. The instant invention is a secure container for the transport and storage of materials, whose location and condition needs to be monitored either real time or near real time. The container employs a wound fiber-optic layer embedded in a covering. An IR transmitter sends light through the fiber-optic layer to a receiver. Any change in the light signal causes an alarm or indication, either locally or at a pre-designated location. The container also gives real-time read outs, remotely or locally, as to the conditions of the contents and the container itself.




The subject matter of the present invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. However, both the organization and method of operation, together with further advantages and objects thereof, may best be understood by reference to the following description taken in connection with accompanying drawings wherein like reference characters refer to like elements.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to FIG.


1


and to

FIG. 2

the instant invention is a secure storage and transport container


1


for the handling of controlled materials


3


within a storage cavity


5


.




Now referring to FIG.


3


and to

FIG. 4

, there are no limitations on the size of the outer shell


7


, or the storage cavity


5


, which is enclosed by a covering


9


that is a supportive structure which supports, and holds in place, a continuous optical fiber


11


that is connected to an electronics package


13


. The instant invention readily lends itself to containers from the size of match boxes up to Conex and Sealand containers.




Now referring to

FIG. 4

, the cargo embodiment, is for the outer shell


7


to be the size of typical hand-held luggage for the transport and control of smaller items or materials


3


within a storage cavity


5


. Another cargo embodiment is for the outer shell


7


to be large enough for the secure container


1


to be accessed, from above or the side, via a man hole or doorway (not shown).




Now referring to

FIG. 3

, yet another embodiment utilizes a drawer for ease of handling the materials


3


and location of the electronics package


13


. Still another embodiment can be used to store and transport gaseous or liquid materials utilizing the outer shell as the actual containment of the materials (not shown). Materials, items, stored items, contents, controlled inventory, and packages will be used interchangeably to indicate the item or thing that is stored or transported within the instant invention.




PHYSICAL STRUCTURE




Now referring to

FIG. 5

the basic physical structure of the instant invention comprises an outer shell


7


having a covering


9


which typically has an optical fiber covering


15


, a non-active fiber covering


17


, and a woven fiber mat covering


19


. The physical structure of the instant invention


1


has an electronics package


13


that is contained within the outer shell


7


. The coverings


15


,


17


,


19


are wrapped in a continuous manner around on the outer shell


7


. It should be noted that the fiber's ability to be woven is an advantage, however, it must also be kept in mind that bending of the fiber reduces the light reaching the detector.




Referring again to

FIG. 3

within the outer shell


7


can be a drawer


21


that contains the materials


3


that are to be transported or stored. For ease of removal, a handle


23


is placed on front end


25


of the drawer


21


.




Referring to

FIG. 5

it is contemplated that one skilled in the art can combine the non-active fiber coating


17


and the woven fiber mat covering


19


into a single outer layer as illustrated in FIG.


3


. It is also contemplated that an uncovered optical fiber cable can be woven around the outer shell then covered in material that is capable of being cast around the optical fiber cable. It is well known in the art to be able to cast materials such as polymers, fiberglass, concrete, etc around cables.




CONNECTION TO ELECTRONICS PACKAGE




Now referring to FIG.


5


and

FIG. 6

the electronics package


13


,


13




a


,


13




b


, can be connected to the optical fiber covering


15


in three principle ways: (I) externally as illustrated in

FIG. 5

; (ii) internally as illustrated in

FIG. 6

which is used in the majority of the applications; or (iii) remotely using, for example, electromagnetic (EM) or infra-red (IR) radiation.




IR radiation is invisible to the naked eye and is readily applicable to commercially available fibers. Visual spectrum light can also be used, as well as having commercially available fibers or use with visible light. The desired spectrum of radiation that is used is typically created by fixed spectrum diode (not shown) that is well known in the art.




If radiation is used as the means of connection the electronics package


13


is typically located within the outer shell


7


for security and ease of handling reasons, as illustrated in FIG.


6


. As illustrated in

FIG. 6

the electronics package


13


would be a transmitter, and another electronic package


13




b


would be the receiver. This embodiment would be particularly valuable in situations where loss of the container itself is possible. The remote electronic package


13




b


would record, process, and provide the necessary indications to the user.




External Connection




Referring again to

FIG. 5

the first connecting lead


27


and the second connecting lead


29


are passed through the non-active fiber


17


covering and the woven fiber mat covering


19


to an external electronics package


13




a


. This embodiment would be best suited for storage applications. Typically, with more than one container in a storage area.




Internal Connection




Referring again to

FIG. 6

the first connecting lead


27


and the second connecting lead


29


are passed through a penetration


31


in the outer shell


7


to the electronics package


13


. The internal connecting means lends itself greater ability to transport or conceal the secure nature of the container


1


. When connected internally the secure container can collect data about any break of integrity or it can transmit (or store) data describing the conditions of the contents or cargo


3


.




Remote Connection




Referring again to

FIG. 5

, it is well known in the art for the internal electronics package


13


to be able to communicate with a non-physically connected external electronics package


13




b


(or other indicating or receiving systems—not shown) via electro-magnetic or infra-red radiation. For example, information concerning the location of the cargo may be communicated by utilizing a GPS system in electronics package


13


. The remote connecting means lends itself greater ability to transport or conceal. With the use of satellites the distances for use is greatly increased.




INDICATION FUNCTIONS OF THE ELECTRONICS PACKAGE




There are four principle functions of electronics package


13


: tamper indication; location indication relative to pre-set boundaries; condition and status data recording and/or transmitting; and notice initiation for a pre-determined set of conditions or occurrences. Conditions considered include, but are not limited to, moisture, light, vibration, chemicals, radiation, movement, or any other detectable quantity.




Each function provides real-time indication of the desired functional feature on the instant invention


1


. The indication provided can be all four types, or alternatively one of each or any combination thereof. It is not germane to the instant invention if the indication produced by the instant invention is used to initiate action or merely to give passive indication. Nor is it germane whether the indications are local or remote from the secure container


1


.




An advantage of the instant invention is that the indication capabilities of the instant invention can be disguised or hidden to an observer.




For each embodiment the electronics package


13


can perform a plurality of functions. For example: indication when the secure container moves across a specified boundary, such indication can also either be internal or external; inventory control of the materials; real-time location of the cargo


3


; or the relationship of the secure container


1


to specified boundaries can be monitored.




Now referring to FIG.


7


and

FIG. 8

the electronics package


13


can be placed in the bottom of the secure container


1


with the cargo


3


placed on or near the electronics package


13


. It should be noted that the electronics package


13


can be placed anywhere within the secure container


1


, i.e. the bottom area


34


, in the lid


33


, or in the walls of the outer shell


7


. To enable access to the secure container


1


, for the storage and removal of cargo


3


, a seam


32


is used to separate the container body


35


from the lid


33


. It is within the contemplation of the invention that the lid


33


may be hinged upon one side (not shown). When the lid


33


is removed the first lead


37


and the second lead


39


are separated, thereby breaking the continuity of the optical fiber. For ease of reuse a coupling


41


is typically used. The seam


32


consists of a lower sealing surface


42


and an upper sealing surface


44


.




Now referring to

FIG. 9

either one of two occurrences can interrupt an IR signal


47


in the optical fiber


11


. The first is for a coupling


41


to be opened, and the second is for a break


49


or alteration


49


to occur in the optical fiber


11


. Within the electronics package


13


, an infra-red transmitter


51


passes an IR signal


47


through the optical fiber


11


to an IR receiver unit


53


. Such that when the optical fiber


11


is breached


49


(or changed


49


) there is a change of the IR light signal


47


at the receiver


53


unit.




Upon sensing a change in the IR signal


47


, the receiver


53


will send an event signal


55


to a processing unit


57


that records the event signal


55


and/or can be used to trigger other events. Whether the event is merely recorded or used to trigger other events depends upon the needs to be fulfilled by the particular embodiment of the instant invention.




Still referring to

FIG. 9

the optical fiber


11


should be spaced close enough together to make breaking or alteration of the optical fiber


11


necessary to be able to access the cargo


3


other than through opening the lid


33


. Alternatively, the covering


9


should be secure enough to necessitate the disruption of the optical fiber


11


should penetration of the secure container


1


be attempted.




Another operational consideration is that the electronics package can be fitted with a connection to a PC or lap-top computer for analysis of the data.




OPERATION OF THE DRAWER EMBODIMENT




Referring again to

FIG. 1

the drawer embodiment of the instant invention is a secure container that is typically luggage size or smaller. This embodiment is typically used to transport items/materials that are either valuable or hazardous, or for any reason, its location and access need to be controlled.




RF TAG SYSTEM




Now referring again to

FIG. 8

, a commercially attractive embodiment is the RF-tag system. In this embodiment


1


of the instant invention an antenna


59


is embedded near the container opening


61


, which antenna reads all items


3


having an RF tag that move across the system boundary. An “RF tag” refers to any item


3


that emits an RF signal that can be detected by the electronics package


13


. The electronics package can store and/or transmit the information.




OPERATION OF THE SEALED CONTAINER EMBODIMENT




When said optical continuous strand is penetrated said indicator system gives an indication to an observer at the desired location.




STRUCTURAL AND PHYSICAL CONSIDERATIONS




It is well known to one skilled in the art that the construction materials used to fabricate the particular embodiment can vary according to the instant invention end use. For example, the materials (including the electronics package) can be radiation insensitive, microwave hardened, heat resistant, acid resistant, impact resistant. If reactive chemicals or elements are shipped or stored in the instant invention then due consideration would have to be given in construction material selection.




The use of fiber optics as the sensing circuit of the instant inventions adds certain advantages. For example, it can't be defeated by electromagnetic radiation. Nor is it possible to use cable jumpers as with conventional electrical circuits.




An advantage of the instant invention is that the indication capabilities of the instant invention can be disguised or hidden to an observer.




REUSE OF CONTAINERS




Inherent in the secure nature of the container that is the instant invention is the need to be able to place the contents in and out of the container and still preserve the usefulness of the container. Couplings (mechanical, electrical, magnetic, etc.) of the optical fiber can be used at or near the place where either the drawer(s)


25


or lids


33


are removed from the outer shell. An internally connected electronics package is typically set with a timer that will give the user time to replace the lid or the drawer.




The use of reusable optical fiber couplings is well known in the art.




MATERIALS TO BE TRANSPORTED OR STORED




Any material that is capable of being contained can be transported or stored in the instant invention. The drawer embodiment lends itself to use with packages that are to be frequently handled by personnel or loading equipment. The sealed container embodiment lends itself to the seal on shipment—open on arrival type shipments.




OTHER EMBODIMENTS POSSIBLE




While several embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from the invention in its broader aspects.
