1. Field of the Invention
The present invention relates generally to an item and/or object tracking system and arrangement, and in particular to an item tracking system and arrangement for use in tracking and managing items and/or objects associated with a signal emitting element, such as a tag, a radio frequency identification tag, a transponder, and the like.
2. Description of the Related Art
In the field of item and/or object tracking, various systems and arrangements have been developed to effectively and accurately track an item, as well as some characteristic or data associated with the item. For example, and as is known in the art, an item can be “tagged” with a signal emitting element that transmits a signal including specific data. This data can be used to track the item, control the flow of items in the system, locate the item amongst multiple items, make decisions regarding the dispensing, movement, purchase, or other action related to the item (or group of items with a similar characteristic), etc. For example, one such item tracking system is shown and described in U.S. patent application Ser. No. 12/240,022, entitled “Dynamic Control Containment Unit,” the entirety of which is incorporated herein by reference. Such tracking systems are useful in connection with tracking various items that are placed within or removed from a specifically-configured containment or storage structure.
There are different types of signal emitting elements, including tag members, radio frequency identification members, transponders, and the like. Some of these members are active, i.e., continuously or periodically “wake-up” and transmit information and data for receipt by some signal receiving member, or passive, i.e., remain dormant until activated by some other device or member, such as a “wake-up-and-transmit” signal from a signal receiving member. As stated, both types of tag members may be used in connection with a tracking system.
However, certain items and/or objects are not amenable to the use of such existing tag members. For example, certain items are too thin or too flimsy to be positioned in a container, e.g., a drawer or a shelf, and effectively tagged, where the system can read the tag and obtain the necessary data. Accordingly, a tag has been developed that can be attached to and extend from a surface of such an item, such as the “flag tag” used by Mobile Aspects, Inc., which has been used in connection with the above-referenced “Dynamic Control Containment Unit” and associated system. Using such an extending tag allows for a thin or flimsy item to be associated with a tag; however, the issues of accuracy and interference are still present.
Currently, in order to effectively identify and establish a data exchange between the signal emitting members, e.g., tag members, and the signal receiving member, e.g., an antenna or the like, a complex and configured structure is required. Further, even such a specialized configuration may not effectively identify all of the tags (and, thus, the associated items) in the containment area based upon the random positioning of the tags. For example, the items may be too close together, thus leading to the contact or close proximity of adjacent tag members. In addition, when the item includes metallic components or features, data emission and receipt from and to the tag will be subject to interference. Therefore, the accuracy of the tracking process may be compromised.
There is considerable room for improvement in the accuracy and effectiveness of item tracking systems, which are deployed throughout many industries and in numerous environments. There is also a need for an item tracking system and arrangement that can be used in connection with specifically-sized or -shaped items and/or objects. In addition, there is a need for an item tracking system and arrangement that can maintain accuracy regardless of the materials used by or integrated with the item-to-be-tracked.
Generally, the present invention provides an item tracking system and arrangement that overcomes or addresses some or all of the deficiencies and drawbacks associated with the prior art. Preferably, and in some preferred and non-limiting embodiments, the present invention provides an item tracking system and arrangement that can be effectively used in connection with specifically-sized or -shaped items and/or objects. Preferably, and in other preferred and non-limiting embodiments, the present invention provides an item tracking system and arrangement that maintains accuracy regardless of the materials used by or integrated with the item-to-be-tracked, for example metallic components or materials.
Accordingly, and in one preferred and non-limiting embodiment, the present invention is directed to an item tracking system including at least one signal emitting element directly or indirectly attached to a portion of at least one item, wherein at least a portion of the at least one signal emitting element extends from the at least one item. The system further includes a container, including: (i) a support surface configured to at least partially support the at least one item and having at least one opening extending therethrough, which is configured to at least partially receive at least a portion of the signal emitting element therethrough; and (ii) at least one signal receiving member configured for communication with the portion of the at least one signal emitting member extending through the at least one opening.
In another preferred and non-limiting embodiment, the present invention is directed to an item tracking container, including: a support surface configured to at least partially support at least one item and having at least one opening extending therethrough, which is configured to at least partially receive therethrough at least a portion of a signal emitting element directly or indirectly attached to a portion of at least one item; and (ii) at least one signal receiving member configured for communication with the portion of the at least one signal emitting member extending through the at least one opening.
In a further preferred and non-limiting embodiment, the present invention is directed to a method of tracking at least one item having at least one signal emitting element attached to at least a portion thereof. The method includes: positioning at least a portion of the at least one signal emitting element through at least one opening extending through a support surface configured to at least partially support the at least one item thereon; and communicating, by at least one signal receiving member, with the portion of the at least one signal emitting extending through the at least one opening.
These and other features and characteristics of the present invention, as well as the methods of operation and functions of the related elements of structures and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures.

However, it is to be understood that the invention may assume various alternative variations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the invention. Hence, specific dimensions and other physical characteristics related to the embodiments disclosed herein are not to be considered as limiting. Further, it is to be understood that the invention may assume various alternative variations and step sequences, except where expressly specified to the contrary.
The present invention is directed to an item tracking system 10 and an item tracking container 12 for use in tracking, locating, or otherwise identifying one or more items I. Certain preferred and non-limiting embodiments of the item tracking system 10 and item tracking container 12 of the present invention are illustrated in
Still further, the item tracking system 10 and container 12 of the present invention include the ability to uniquely identify the item I in an environment by using signal identification, transmission, receipt, and processing functions, and should not be limited to any particular type of signal processing system or infrastructure. In one preferred and non-limiting embodiment, the item tracking system 10 and container 12 of the present invention are utilized in connection with a radio frequency identification (RF/ID) environment. However, other similar signal tracking arrangements may be utilized without departing from the spirit and scope of the presently-invented item tracking system 10 and container 12.
Any wireless data transfer and communication architecture can serve as the basis of the present invention. For example, the system 10 and container 12 of the present invention can be configured for effective use in a bar code system, an optical character recognition system, an image recognition system, or the like. Accordingly, any system that permits the emission, sensing, and/or receipt of a signal associated with or containing data can be used or implemented within the context of the present invention.
Still further, the present invention may be used to manage and track items I that have a specific configuration, size, or shape, including, but not limited to, flimsy items I, thin items I, items I that contain metallic components or features, items I that are contained in metallic packaging, etc. In particular, it is one object of the present invention to provide an item tracking system 10 and container 12 that can be used in an RF/ID environment and still accurately and consistently identify the item I, based at least in part upon the signals and data associated therewith. Still further, and in some preferred and non-limiting embodiments of the present invention, the system 10 and container 12 are arranged to displace or space the tag (or signal emitting element) from the body of the item I (or packaging containing the item I) when the item I or packaging includes metallic portions. Accordingly, the system 10 and arrangement of the present invention assist in reducing the “de-tuning” effect on the radio frequency field, which is a known issue that may arise when interacting with metallic components in an RF/ID environment.
With reference to
It is envisioned that the signal emitting element 14 can be an “active” tag or a “passive” tag, as discussed above in connection with the known prior art. In addition, the data that is stored on the signal emitting element 14 can be embedded therein, programmed thereon, or otherwise associated with the signal emitting element 14. In addition, this data may include item data, packaging data, item grouping data, characteristics of the item, identification of the item, location data, interaction data, expiry data, condition data, alert data, signal emitting element data, system data, container data, or any other information that would be useful in managing and tracking items I in the system 10.
With continued reference to
As also illustrated in
In the preferred and non-limiting embodiment of
With further reference to
A central controller 34 may also be used, and this central controller 34 may include any of the above functions. Further, the central controller 34 may be used in managing multiple containers 12 within the item tracking system 10. Accordingly, the central controller 34 may be positioned remote from one or more of the containers 12, and in wireless (or hardwired) communication with the local controller 30 and/or the signal receiving member 24. Any type of communication between the various components of the container 12, as well as within the system 10, is envisioned.
As seen in
With reference to
In addition, any appropriate sensing arrangement and configuration may be used to determine the presence of a signal emitting element 14 extending through an opening 22 (or slot). Such a sensing arrangement may include a physically-activatable switch, a transducer, a capacitor, a conductive element, or the like. As discussed, this provides a faster scanning process.
Still further, the local controller 30, the central controller 34, or some other programmable component of the system 10 could be configured to scan specified portions or areas of the container 12. As discussed above, the instructions to only scan or read the signal emitting elements 14 in a specified portion or area may be based upon the presence of one or more signal emitting elements 14 in the lanes 36 (or other designated area or portion in the container 12). Such an instruction may also be determined based upon other data available to the local controller 30 and/or central controller 34. For example, if specific items I are placed only in specific areas or portions of the support surface 20, and only these specific items I need to be tracked or scanned at some point in time, then the scanning area of the signal receiving member 24 could be reduced and specified. This also provides much faster scanning times within the system 10, thus yielding greater efficiencies in the tracking process.
A further preferred and non-limiting embodiment of the present invention is illustrated in
While the container 12 may take a variety of forms, in the preferred and non-limiting embodiment of
As shown in
A still further preferred and non-limiting embodiment of the present invention is illustrated in
Accordingly, the present invention provides an item tracking system 10 and container 12 that is accurate and particularly useful in connection with specific types of items I (or packaging associated with such items I). Again, the slots 26 may be non-continuous, such that the signal emitting elements 14 can only be placed into specific areas on the support surface 20. For example, this “forced” orientation may ensure that the signal emitting elements 14 do not overlap with adjacent areas of the containment area, whether above or below the support surface 20. This reduces “tag shading” and/or interaction. As also discussed, spacers 42 can be used to optimally orient the signal emitting elements 14 for communication with the signal receiving member 24. Accordingly, the signal receiving member 24, such as an antenna, can also be optimized for the determined and known orientation of the signal emitting elements 14. By using lanes 36 and/or the optical sensing arrangement 38, activation of the signal receiving member 24 (or portions thereof) can be controlled, thereby increasing scan speeds.
In general, controlling the spatial separation between a metal surface (e.g., a surface or component of the item I (or packaging)) and the signal emitting elements 14, as well as the signal receiving member 24, ensures that the effect of the metal in a radio frequency environment is minimized. Accordingly, the item tracking system 10 and container 12 of the present invention represents an improvement on the current method of handling items with metal content or packaging without the need for complex modifications in container design. For example, the container 12 of the present invention can be used and easily positioned in connection with existing systems.
Still further, the present invention leverages gravity to deterministically set the distance between signal emitting elements 14 and the signal receiving member 24 at a fixed distance. The signal emitting elements 14 do not shade or interfere with each other, and very thin or “flimsy” items I (or associated packaging) can be tracked, since the signal emitting portion 18 of the signal emitting element 14 is appropriately managed and oriented. Further, mixed-sized and -shaped items I can be co-mingled on the same support surface 20, since the substrate does not impact the location of the signal emitting element 14.
In addition, shielding can be used in any portion of the container 12 in order to isolate the signal emitting portion 18 of the signal emitting element 14, and reduce or eliminate interference. Further, the support structure of the signal receiving member 24 may be made lightweight, as it is not required to support the weight of the items I positioned above it. Still further, the defined orientation of the signal emitting element 14 may permit the use of two-dimensional antennae, rather than the more complex and costly three-dimensional antennae. This will improve reading speed, lower costs, and improve manufacturability.
Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred embodiments, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
