APPLICATION FIELD [001] The present application for a patent refers, in general, to inventory tracking and, more particularly, to an inventory tracking system that uses RFID tags. TECHNICAL STATUS [002] The evolution of radio frequency identification (RFID) has made it possible to wirelessly control inventory items by attaching an RFID tag to each item in the inventory and wirelessly detecting the RFID tag using a set of sensory antennas. If the antenna array can detect the RFID tag, a decision is made that the corresponding item is present in the inventory. On the other hand, if the antenna array does not detect the RFID tag, a decision is made that the corresponding item is not present in the inventory. [003] An operational issue in wirelessly tracking inventory items is that a set of antennas cannot detect an RFID tag that is in a "blind spot" with respect to the set of antennas. For example, an RFID tag may be obstructed from the antenna array by another item in the inventory, or an RFID tag may be oriented in a direction in which the antenna array has low directional sensitivity, resulting in a loss of reading of the RFID tag by the array. antennas. [004] In certain applications, inventory tracking errors, such as errors caused by a failure to read an RFID tag by a set of sensory antennas, can have relevant undesirable operational consequences. For example, in a healthcare facility, incorrect charges may arise from an item that has been wrongly tracked as having been removed from a medicine cabinet. RESUME [005] The features discussed above and other concerns are addressed by inventory tracking systems and methods in accordance with various configurations described in the present application for an invention patent. [006] In one aspect of the present patent application, an inventory control method comprises the association of a plurality of radio frequency identification (RFID) values corresponding to a plurality of RFID tags with an inventory item, the affixing a plurality of RFID tags to a plurality of surfaces of the inventory item in such a way that the antenna axes of the plurality of RFID tags are oriented in a plurality of directions, wirelessly detecting the RFID tags affixed to the items in the inventory, using a set of antennas comprising one or more antennas and deciding, if one or more RFID is detected from the plurality of values associated with the inventory item, that the inventory item is present in the inventory, otherwise, decide that the inventory item is not is present in the inventory. [007] In another aspect of the present patent application, an inventory control system comprises an RFID tape comprising a plurality of RFID tags mounted on a substrate, the RFID tape attachable to an inventory item using a lower surface substrate adhesive, a set of antennas comprising one or more antennas configured to detect RFID tags and a computer coupled to the set of antennas and configured to control a plurality of items in the inventory. [008] In yet another aspect of the present patent application, an RFID tag tape for use in an inventory tracking system comprises a substrate having a top surface and a bottom surface, a plurality of RFID tags mounted on the top surface of the substrate, each RFID tag comprising an antenna for transmitting and receiving radio frequency signals, and an adhesive layer covering the bottom surface of the substrate, the adhesive layer provided for affixing the RFID tag tape to an inventory item . Each of the various RFID tags has a unique identifier associated with it. The RFID tag tape can be wrapped on a roll. [009] The foregoing characteristics and other characteristics, aspects and advantages of the embodiments of the present invention will become more evident from the following detailed description and the accompanying drawings.

DETAILED DESCRIPTION [0010] The configurations of this invention patent application discuss and resolve problems related to the control of inventory items, providing, in part, a method of marking inventory items with multiple RFID tags and tracking of inventory items based on detecting any of the multiple RFID tags. In one aspect, an RFID tag strip is disclosed which comprises a linear arrangement of RFID tags to facilitate easy application to multiple areas of the surface of an inventory item. [0011] In general terms, two or more RFID tags are respectively applied to multiple surfaces of an inventory item so that, regardless of the position and orientation of the inventory item, a set of antennas is capable of detecting at least one of the RFID tags attached to the inventory item with a very high degree of probability. [0012] In certain aspects, a computer system is released for tracking inventory items marked with multiple RFID tags. A user can enter multiple RFID tag identification values in a database communicating with the computer system and associate the multiple RFID tag identification values with a single inventory item. The computer system makes a decision as to the presence or absence of the item in the inventory, checking if any of the RFID tags associated with the item are detected by a set of antennas coupled to the computer system. [0013] As used herein, an RFID tag can be one of the well-known types of RFID tag such as a magnetically coupled RFID tag, an electrically coupled RFID tag or a multi-frequency RFID tag. Likewise, an antenna array used to detect RFID tags can comprise detection antenna elements using magnetic or electrical coupling RFID tags or multiple frequencies. [0014] Figures 1A and 1B illustrate prior art RFID inventory tracking systems that highlight some operational problems associated with inventory tracking by attaching a single RFID tag and / or affixing RFID tags to a single surface of an inventory item. In particular, figure 1A shows an example in which inventory item 102 is oriented to maximize the probability of successful detection of inventory item 102 by an RFID antenna 104 and figure 1B shows an example where inventory item 102 it is oriented to stay in the blind spot of RFID antenna 104, causing the RFID antenna 104 to lose detection of item 102. [0015] Figure 1A is a schematic representation of a portion of the prior art RFID 100 inventory tracking system. Computer 128 is equipped with a communication module (e.g., an RFID transmitting circuit board) configured to transmit and receive messages with antenna array 104. Antenna array 104 is configured to detect RFID tags. The antenna array 104 may include a single antenna or multiple antennas positioned at various locations (for example, on the top and bottom surfaces of a medicine cabinet) to detect inventory items in different orientations. In certain configurations, the individual antennas of an array of antennas 104 are planar metal coil arcs. A planar antenna, such as the antenna 114 shown in FIG. 1A, typically has non-isotropic radio frequency (RF) field characteristics. In other words, a planar antenna generally has a different reception and / or transmission efficiency in different directions. For example, it is well known that a planar antenna coil typically radiates more energy in the direction orthogonal to the plane of the antenna coil. For example, axis 114 in FIG. 1A represents the direction of the best transmission / reception performance by the antenna array 104. The lack of non-isotropic performance of a single antenna is resolved, in known solutions, using multiple antennas, oriented in different directions, to achieve an equivalent performance of RF in all directions. However, using multiple RF antennas is expensive and undesirable due to the increased amount of time required to perform scanning operations with multiple RF antennas. [0016] Still with respect to figure 1A, the item of inventory 102 has an RFID tag 106 affixed. In certain configurations, RFID tag 106 is a planar tag. As is well known in the art, a typical RFID tag 106 includes an antenna 126 used for RF communication with the antenna array 104. Antenna 126 is, for example, a coil for magnetic field communication and a dipole antenna for electric field communication with an array of antennas 104. In general, antenna 126 has a sensitivity axis 108 and the communication sensitivity drops as the angle between the sensitivity axis 108 and the sensitivity axis 114 of the antenna array 104 increases. The transmission / reception signal performance of RFID tag 106 will typically be better when sensitivity axes 114 and 108 are aligned. The coupling between RFID tag 106 is reduced as the angle between the sensitivity axes of 114 and 108 increases, effectively becoming zero when the two axes are at right angles, as shown in figure 1B. [0017] Figure 1B shows the configuration 150 of a portion of a system 100 with an item from inventory 102 oriented in a different direction compared to figure 1A. Inventory item 102 is now oriented so that the RFID tag 110 affixed has its antenna axis 112 orthogonal to the antenna axis 114. With the antenna axis 112 of RFID tag antenna 126 orthogonal to the antenna axis 114 of the antenna array 104, in general, antenna array 104 may be in a "blind spot" of antenna array 104, that is, antenna array 104 may not be able to "see" or detect RFID 110 tag with high probability of success due to poor coupling between antenna array 104 and RFID tag 110. In some guidelines of inventory item 102, antenna array 104 may not be able to detect RFID tag 110 at all. Even if inventory item 102 is designed to avoid the operational problem of RFID tag 110 misdirection, for example, by providing visual cues to a user on where to attach RFID tag 110 and how to place inventory item 102 in inventory (for example, example, printing a "this side up" notice on inventory item 102), inventory item 102 could be misdirected due to the fall of inventory item 102 during storage and use or by user error in choosing correct surface of inventory item 102 when applying RFID tag 110. [0018] With respect to Figures 1A and 1B, in general, the antenna axis of inventory item 102 can be at an angle between a completely aligned position (for example, as shown in FIG. 1A) and a fully orthogonal position ( for example, as shown in FIG. 1B). Therefore, in general, the detection of inventory item 102 by the antenna array 104 is a probabilistic event, with the highest probability of detection when the antenna axis is aligned with the antenna axis 114 of the antenna array 104 and the smallest probability of detection when the antenna axis is orthogonal to the antenna axis 114. During operation, inventory item 102 may reorient due to a fall or obstruction causing inventory item 102 not to be detected by antenna array 104, causing inventory tracking computer 128 to show incorrect status of inventory item 102. [0019] Figure 2A is a schematic representation of a portion of the RFID tag strip 202, according to certain configurations of the present application. In some respects, RFID tag tape 202 is useful for overcoming operational problems related to misalignment of the antenna axes. The RFID tag ribbon 202 comprises a plurality of RFID tags 204, each having the antenna coil 206. In certain configurations, the RFID tags 204 are arranged on the stamp-like RFID tag tape 202 on a roll of postage stamps. In certain configurations, RFID tags 204 may be of more than one type, for example, a magnetically coupled RFID tag, an electrically coupled RFID tag or a multi-frequency RFID tag. [0020] In certain configurations, each RFID tag 204 is individually detachable from the RFID tag tape 202. The RFID tag 204 is permanently attached to the RFID tag tape 202 and the RFID tag tape 202 is configured to be attached to an item of the inventory 102 (for example, providing an adhesive bottom side). In certain other configurations, in operation, a user can unwind a roll of RFID 202 label tape, cut or detach a desired length of the tape, and wrap and affix a desired length around an inventory item. In certain configurations, each RFID tag 204 has a unique identification number associated with the RFID tag 204. In certain configurations, the identification numbers of the RFID tags 204 adjacent to another RPID tag 204 on the RFID tag strip 202, are contiguous ( for example, identification numbers 0x01, 0x02, 0x03, and so on). In certain configurations, the identification numbers of RFID 204 tags are in a random order. In certain configurations, the RFID tag tape 202 is made of a flexible plastic material or paper in such a way that the RFID tag tape 022 can be wound onto a roll. [0021] Figure 2B is a schematic representation of a portion of the RFID tag strip 202, according to certain configurations of the present patent application. In the configuration shown in FIG. 2B, RFID tag tape 202 includes perforations 232 between each two RFID tags 204 to help the user easily tear the RFID tag tape 202. In general, certain configurations of RFID tag tape 202 may include perforations 232 after a number regular RFID tags 202 (for example, between every two or three RFID tags 204) or irregularly spaced (for example, after each N RFID tags 202, where N is an integer between 1 and 10). [0022] Figure 2C is a schematic representation 260 of a portion of the RFID tag strip 202, according to certain configurations of the present patent application. In the configuration shown in FIG. 2C, RFID tag tape 202 includes RFID tags 204 positioned on the RFID tag tape 202 at irregular intervals and in random orientations. The diagrammatic representation 260 shown includes holes 232. In various configurations, holes 232 can be placed differently or can be omitted. In one aspect, the random orientation of RFID tags 204 facilitates the random orientation of the corresponding sensitivity axes 108, when a portion of the RFID tag strip 202 is affixed to a surface of an item in the inventory. [0023] Figure 2D is a schematic representation of a portion of the RFID tag strip 202, according to certain configurations of the present application for an invention patent. Figure 2D illustrates a cross-sectional view of the RFID tag strip 202 along the plane of the RFID tag strip 202 seen in the direction of arrow IIB in figure 2A. RFID tag tape 202 comprises a substrate 222 made from a firm but flexible material, such as transparent plastic or paper tape. The RFID tag strip 202 further comprises an RFID tag 204 mounted on the top surface 228 of the substrate 222. In certain configurations, the RFID tag 204 is mounted on the top surface 228 using a non-removable adhesive. In certain configurations, the RFID tag 204 is mounted on the upper surface 228, establishing electronic components (for example, antenna coil 206 and an integrated circuit 205) of the RFID tag 204 on the upper surface 228 and covering the electrical components for a Protective Case. In certain configurations, the RFID tag strip 202 comprises a substrate 222 covered with an adhesive layer, on which a plurality of RFID tags 204 are positioned such that, during use, an RFID tag 204 can be removed from the tag tape RFID 202 and applied to an item in inventory 102. [0024] In certain configurations, adhesive layer 224 covers the lower surface 229 of substrate 222. In certain configurations, adhesive layer 224 is covered by an optional peel-off layer 226. Peel-off layer 226 protects adhesive layer 224 from unwanted adhesion before affixing to an item in inventory 102 by a user. A user will peel off the peelable layer 226 and affix RFID tag tape 202 to an item in inventory 102. In certain configurations, peelable layer 226 is made of a peelable non-stick material, such as wax paper or a thin plastic film non-adherent. Adhesive layer 224 is made from one of several well-known pressure sensitive adhesive materials, such as epoxy, in certain configurations. [0025] The protective layer 220 is applied to the upper surface 222 and to the RFID tag 204 to protect the antenna elements electrically sensitive to wear during storage and use. In certain configurations, when RFID tag tape 202 is wrapped in a roll of tape, protective layer 220 is useful for protecting the upper surface 222 from adhesion with adhesive layer 224. In certain configurations, protective layer 220 is made of a plastic that is "transparent" to the RF signals transmitted and received by the 206 antenna coil (an electrically non-conductive plastic, for example). [0026] Figure 2E is a schematic representation of a sheet of RFID 238 tags, according to certain configurations of the present application for an invention patent. In the configuration illustrated in FIG. 2E, RFID tags 204 are arranged in three lines on RFID tag sheet 238. The "gift wrapping" configuration of RFID tag sheet 238, as shown in FIG. 2E, is useful for affixing RPID 204 tags over a large surface of inventory item 102. In general, RFID tags 204 can be arranged in a plurality of lines on the RFID tag sheet 238, or can be mounted on the sheet of RFID 238 tags in any other two-dimensional standard (eg random placement). In certain configurations, the RFID 238 label sheet is stored similarly to a cylindrical roll of gift paper. [0027] Figure 2F is a schematic representation of an RFID 262 tag, according to certain configurations of the present application for an invention patent. In the configuration illustrated in FIG. 2F, several RFID 204 tags are randomly oriented and positioned on RFID tag 262. The configuration of tag 262 is useful for affixing RFID tags 204 on a surface of inventory item 102 by applying a single RFID tag 262 to the surface. In one aspect, the random orientation of RFID tags 204 helps to improve the coupling with the antenna array 104, regardless of the orientation of the inventory item 102. [0028] Figure 2G is a schematic representation of a roll of RFID tag tape 202. The roll of RFID tag 250 is described as having a rolled portion 252 and a rolled strip portion 254 (for example, for display during use ), with a plurality of RFID tags 204 visible in both the rolled portion 252 and the rolled strip portion 254. [0029] Still with reference to figure 2E, the greater two-dimensional length of the RFID 238 tag sheet compared to the RFID tag tape 202 makes it useful for application in a large two-dimensional area (for example, large surface area of an inventory item 102 in the form of a pizza box). In certain configurations, the RFID 238 label sheet is manufactured from the same materials, described with reference to Figures 2A to 2D. [0030] Figure 3A is a schematic representation of an RFID 300 inventory tracking system, in accordance with certain configurations of the present invention patent application. Inventory item 102 is "wrapped" with RFID tag tape 202, such that a plurality of surfaces of inventory item 102 are affixed with at least one RFID tag 204. While inventory item 102 is represented in FIG. 3A as having a cubic shape, the general inventory item 102 can be of any shape and can have non-uniform surfaces (e.g., a rounded surface). Regardless of the shape of the inventory item 102, a user can generally attach one or more pieces of RFID tag tape 202 to various surfaces of the inventory item 102 in such a way that the RFID tags are affixed with the antenna axes pointing in different directions in relation to each other. In certain configurations, individual RFID tags (for example, RFID tag 302) can be wrapped around the edge of inventory item 102. [0031] Still with reference to figure 3A, in certain configurations, the computer 128 is still coupled to the tracking antenna 140 via a communication module, such as a printed circuit board (not shown). A user uses the tracking antenna 140 to associate a plurality of RFID tags 204 with a single item in inventory 102, before or after affixing the plurality of RFID tags 204 to inventory item 102. The association operation is further described below. Tracking antenna 140 may, for example, be an RFID antenna, a barcode scanner or other of the many well-known communication devices configured to interface with computer 128. Tracking antenna 140 is not essential. For example, in certain configurations, the set of antennas 104 can be configured to perform operations of antenna 140. In certain configurations, the user can use a keyboard and / or a touch screen to associate the plurality of tags RJFID 204 with a single item from inventory 102. [0032] In system 300, RFID tags are affixed around inventory item 102 in such a way that the three axes of antenna 108, 109 and 110 make inventory item 102 "visible" to antenna array 104, regardless the orientation of inventory item 102 with respect to antenna axis 114 for antenna array 104. This ensures the low probability of error in counting items in inventory 102, regardless of the placement and orientation of inventory item 102. In general, for an item in inventory 102 that has non-uniform surfaces, the application involving an RFID tag strip 202 affixes multiple RFID tags 204 in multiple orientations, thus increasing the likelihood that one or more RFID tags 204 will be detected by the antenna array 104, regardless of the orientation of inventory item 102 with respect to antenna array 104. [0033] Still with respect to figure 3A, on certain occasions, for a successful detection of the item of inventory 102 by the antenna array 104, the alignment of antenna axes of the RTID 204 tag and of the antenna array 104 may not be sufficient . For example, inventory item 102 has three additional surfaces, not visible in Figure 3A, corresponding to surfaces opposite the visible surfaces. The antenna axis for both RFID tags 204 affixed to the right side surface 302 and the corresponding left side surface (not visible in figure 3A.) Are in the direction of the antenna axis 108. However, it is possible that, for the inventory 102 affixed to the surface on the left side, even when the axis of the RFID tag antenna 204 is aligned in the direction of the antenna array 104, RF detection by the antenna array 104 may not happen, as the inventory item 102 may mitigate the communication signal path between the RFID tag 204 affixed to the left side surface and the antenna array 104. Therefore, in general, to increase the probability (for example, 99.999%) of detection of inventory item 102 by the antenna array 104, the RFID 204 tag must both have its antenna axis aligned with that of the antenna array 104 and the RFID 204 tag must also not be occluded by an item from inventory 102 to which the RFID 204 tag has been r affixed (for example, unobstructed line of sight between antennas 104 and RFID tag 204). [0034] By way of example, and not by way of limitation, certain configurations of inventory tracking systems are now described in accordance with the principles of the present disclosures. While the settings are described with reference to the storage of medical inventory items in a health facility, the same principles apply to any inventory tracking system. Some examples include mail storage facilities, store inventory in stores, and so on. [0035] Figure 3B is a schematic representation of the RFID 350 inventory tracking system, according to certain configurations of the present invention patent application. In a healthcare facility, inventory items 102 may be medicine packs, vials or surgical instruments stored in medical supply cabinets 352. Antenna set 104 may comprise antennas placed along side surfaces of the doctor's office, for example, at upper surface 354 and lower surface 356 of the medical cabinet. During operation, various items from medical inventories can be placed or removed from the doctor's office, stored on 358 shelves. Medical inventory items are often stacked on top of each other. Since RFID tag tape 202 is wrapped around inventory items (for example, inventory item 102), medical inventory items in the doctor's office can be detected with a very high probability, regardless of the orientation of the medical inventory items or occlusion by other items in inventory 102. In certain configurations, the use of RFID tag tapes 202 can also advantageously help to reduce the number of antennas used in antenna array 104. For example, inventory items in a cabinet medical storage can be controlled with a high degree of confidence using only two antennas, one positioned at the top of the cabinet and the other positioned at the bottom of the cabinet, instead of having antennas on all surfaces, such as the sides and the side back of the medical storage cabinet. As is well known in the art, capital expenditures and the time taken to detect items in the inventory could increase with the number of antennas used for the detection of RFID tags. In addition, it may be desirable to keep the number of RF transmission antennas low in order to minimize the risk of electromagnetic interference with patients and other medical equipment, as well as doctors and nurses. In some respects, the application involving RFID tag tape 202 advantageously facilitates the operation of an inventory tracking system with fewer antennas than an inventory management system in which more antennas are positioned to provide a low probability of errors in the asset tracking. [0036] Figure 4 is a flow chart of the operations of the inventory tracking process 400, according to certain configurations of the present invention patent application. Process 400 is implemented, for example, on computer 128. In operation 402, an association is made between a plurality of RFID tag values corresponding to a plurality of RFID tags and an inventory item. To facilitate operation 402, a user sets computer 128 to "register RFIDs" mode. In this mode, a user enters, in no particular order, the identity of an inventory item and one or more RFID tag values to be associated with the inventory item on computer 128. The identity of the inventory item is, for example, a string of alphanumeric characters. The user can also, optionally, enter a description of the inventory item (for example, "100 tablets of medicine X"). The user enters the identity of the inventory item, as well as any description associated with it, using, for example, a keyboard or touch screen in communication with the computer 128. In certain configurations, the user selects the inventory item identity from a drop-down list of all possible types of inventory items. [0037] Still regarding operation 402 of Figure 4, a user introduces the plurality of RFID tag values to be associated with the inventory item, inserting the plurality of RFID tag values using one of a variety of methods. For example, in certain configurations, the user uses a tracking antenna 140 on computer 128 that is different from any antenna in the RFID antenna array 104 used for the items detected in the inventory. To use the tracking antenna 140, the user holds the corresponding RFID tags in the vicinity of the tracking antenna 140, possibly at a specific angle, to wirelessly detect the RFID tags and communicate to the computer 128 the detected values of the RFID tag for association with the inventory item. In certain configurations, RFID tags can have human-readable or computer-readable tag values on them (for example, a barcode or an alphanumeric string) and the user can use a barcode scanner or manually enter the values of RFID tags on computer 128. In certain configurations, the RFID tag values to be associated with the inventory item can be in a sequential order and the user types a start tag value and an end tag value (or a range) to associate all values within the range and including the start tag value and the end tag value in the sequence of values with the inventory item. In certain configurations, there is a one-to-one correspondence between the value of the RFID tag that a user associates with an inventory item and the values of the RFID tags on the portion of the RFID tag strip 202 that a user pulls out for display on the inventory item. [0038] Still with respect to figure 4, in operation 403, the plurality of RFID tags is affixed to a plurality of surfaces of the inventory item in such a way that the antenna axes of the plurality of RFID tags are oriented in a plurality of directions . In certain configurations, affixing the plurality of RFID tags to a single surface may be sufficient to make the inventory item "visible" to the antenna array 104 due to variations in the locations, orientations and sensitivities of the RFID tags individually from the plurality of RFID tags (e.g., the RFID tag ribbon 260 shown in FIG. 2C or RFID tag label 262 shown in FIG. 2F). A user can perform the display, for example, by unrolling a roll of RFID tag tape 202, cutting a portion of the RFID tag tape 202, and affixing the portion of the RFID tag tape 202 on one or more item surfaces of the inventory 102 The user can repeat the cut and display until several or all of the external surfaces of the item in inventory 102 have at least one RFID tag 204 affixed to them. [0039] Still with reference to FIG. 4, in certain configurations, the display operation 403 is performed before the association operation 402. In such configurations, a first user affixes the RFID tags on various surfaces of the items of inventory 102 and then associates the values of the RFID tags attached with the inventory item by tracking or detecting the inventory item using antenna array 104 or tracking antenna 140. [0040] After the 402 association operation and the 403 display operation have been carried out, the user places the inventory item in the inventory (for example, the supply office). [0041] Still with respect to figure 4, in operation 404, computer 128 can wirelessly detect RFID tags 204 in the inventory using antenna set 104. Computer 128 performs operation 404 continuously, periodically or upon the occurrence of certain events (for example, opening an inventory door). As is well known in the art, detection is performed by a computer 128 that transmits query messages requesting responses from RFID tags 204 in the transmission range of antenna array 104. Computer 128 directs query messages, directing query messages for all RFID tags or for a subset of RFID tags, as indicated in an address field in a forwarded query message. When antenna array 104 receives RF signals with RFID messages from RFID tags 204, antenna array 104 communicates received messages to computer 128. Computer 128 then processes incoming messages to extract RFID tag values present in them, if any. [0042] From time to time, or when certain events occur (for example, opening a door to an inventory storage area), computer 128 performs operation 406 to determine whether the values of the detected RFID tags correspond to the known inventory items (that is, inventory items for which associative operation 402 was previously performed). If one or more detected values of the RFID tag correspond to one of the plurality of values associated with the RFID tag with an inventory item, then computer 128 decides that the inventory item is present in the inventory (operation 410). Conversely, if none of the detected RFID tag values match any of the plurality of associated RFID tag values with an inventory item, then the computer decides, in operation 412, that the item is not present in the inventory. In operation 414, computer 128 updates an inventory database to reflect the decision made in operation 410 or in operation 412. [0043] Figure 5 is a block diagram illustrating certain relevant modules of computer 128, according to certain configurations of the present application for an invention patent. Those skilled in the art will understand that the various illustrative modules can be implemented as electronic hardware, computer software, or combinations thereof. Computer 128 comprises a tag 502 association module. In certain configurations, a tag 502 association module can perform the operation 402 described above. Computer 128 comprises the detection module of the label 504. In certain configurations, the detection module of the label 504 performs the operation 404 described above. Computer 128 includes inventory tracking module 506. In certain configurations, inventory tracking module 506 performs operations 406, 410, 412 and 414 described above. [0044] Figure 6 is a block diagram illustrating the computer system 600, according to certain configurations of the present application for an invention patent. In certain configurations, computer system 600 operates like computer 128 used for inventory control. Computer system 600 includes a bus [bus] 602 or other communication mechanism for communicating information, and a processor 604 coupled to bus 602 for processing information. Computer system 600 also includes memory 606, such as random access memory ("RAM") or other dynamic storage device, coupled to bus 602 to store information and instructions to be executed by processor 604. Memory 606 also it can be used to store variable temporary information or other intermediate information during the execution of the instructions to be executed by the 604 processor. The computer system 600 also includes a data storage device 610, such as a magnetic disk or optical disk, coupled to the bus 602 to store information and instructions. [0045] The computer system 600 can be coupled, via the I / O module 608, to a display device (not shown), such as a cathode ray tube ("CRT") or liquid crystal display ("LCD" ") to display the information to a computer user. An input device, such as, for example, a keyboard or mouse, can also be attached to computer system 600 via I / O module 608 to communicate information and command selections to processor 604. The computer system 600 also includes a communication module 612 to interface with external communication components, such as RFID antenna 104 or tracking antenna 140. [0046] According to one aspect, inventory management is performed by a computer system 600, in response to a processor 604 that executes one or more sequences of one or more instructions contained in memory 606. Such instructions can be read in memory 606 from another machine-readable medium, such as a data storage device 610. The execution of the instruction sequences contained in main memory 606 causes processor 604 to perform the steps of the process described here. One or more processors in a multiprocessing arrangement can also be employed to execute the instruction sequences contained in memory 1206. In alternate aspects, physically connected circuits can be used in place of or in combination with the software instructions to implement various aspects. Thus, aspects are not limited to any specific combination of hardware and software circuits. [0047] The term "machine-readable medium", as used here, refers to any medium that operates by providing execution instructions to a processor. Such a medium can take many forms, including, but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media include, for example, optical or magnetic disks, such as a data storage device. Volatile media include dynamic memory. Transmission media include coaxial cables, copper wires and optical fiber, including the wires that make up a bus in connection with processors and memory sections. The transmission means can also take the form of acoustic or light waves, such as those generated during radio frequency and infrared data communications. The most common forms of machine-readable media include, for example, a floppy disk, a floppy disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD, any other optical medium, perforated cards, paper tape , any other physical medium with hole patterns, a RAM, a PROM, an EPROM, an EPROM FLASH, any other memory chip or cartridge, a carrier wave, or any other medium from which a computer can read. [0048] Those skilled in the art will understand that the various illustrative sections, modules, elements, components, methods, and algorithms described herein can be implemented as electronic hardware, computer software, or combinations of both. In addition, these can be partitioned differently than what is described. To illustrate this interchangeability of hardware and software, several illustrative sections, modules, elements, components, methods and algorithms have been described above, generally in terms of their functionality. Whether their functionality is implemented as software or hardware depends on the particular application and design restrictions imposed on the system as a whole. Qualified professionals can implement the functionality described in different ways for each specific application. [0049] It is understood that the specific order or hierarchy of steps or sections in the described processes is an illustration of exemplary approaches. Based on design preferences, it is understood that the specific order or hierarchy of steps or sections in processes can be reconfigured.
