DETAILED DESCRIPTION OF THE INVENTION

[0032] Although the present invention will be described hereinbelow mainly in association with tools in the form of meat or meat processing hooks and knives and further in association with detectable wireless tags in the form of RFID tags, the invention is not so limited. Tools have been described above as including, but not limited to, knives, meat cleavers, steels, meat or meat processing hooks, manual meat and bone saws and meat tenderizers, while detectable wireless tags have been described above as including, but not limited to, RFID tags, UWB tags, WiFi location tags and IR location tags.

Tool

[0033] As noted above, exemplary tools for use in the present invention include, but are not limited to, meat or meat processing hooks and knives. Each tool comprises a working portion with a projection or tang by which the working portion (e.g., a hook or a blade) of the tool is held. Such tools, which are typically made of metal (e.g., steel), are widely available from known manufacturers.

RFID System

[0034] A typical RFID system includes two primary types of components, namely, a reader device and a tag.

[0035] The RFID tag is typically a very small label-like device assembly containing an integrated circuit (“IC”) chip and an antenna mounted on a flexible plastic or paper substrate. The tag can respond, via a wireless air interface channel, to a Radio Frequency (RF) interrogation signal generated and transmitted by the reader device. The RFID tag is configured to generate a return reply signal in response to the RF interrogation signal emitted by the reader, the response signal being modulated in a manner to convey identification (e.g., a unique code or identifier for the tool) or other data stored within the tag or remotely in the cloud (e.g., on the Internet) back to the reader device. The term “cloud”, as used herein, is meant to broadly encompass all remote data storage configurations.

[0036] The RFID tag used in the practice of the present invention is “passive”, meaning that the tag has no battery and is excited and powered by the reader/antenna signal. This is different from an “active” tag, which contains a battery, and thus is self-powered.

[0037] The substrate serves to hold the tag components together. The tag antenna is deposited or printed on the substrate, and the IC chip is then attached to this antenna. The substrate, as noted above, is usually made from flexible material such as a flexible plastic or paper material, but it may also be made from a rigid material (e.g., a ceramic material). Most passive tags use substrates made from flexible material with a preferred thickness ranging from about 50 to about 200 micrometers (μm). Passive tags using substrates made from a rigid ceramic material have a preferred thickness ranging from about 2.0 to about 3.0 millimeters (mm).

[0038] The substrate material must be able to withstand various environmental conditions through which the tag may pass during its lifespan. Some of the materials used for the substrate include, but are not limited to, paper and polymers such as phenolics, polyamides (nylons), polyesters, polyethylene terephthalate (PET), polypropylene, polyvinyl chloride (PVC), and styrene. The substrate material must provide a smooth printing surface for antenna layout, mechanical protection for the antenna, chip, and their interconnections, dissipation of static buildup, and durability and stability under various operating conditions. Some of the environmental conditions that can affect the substrate are heat, moisture, vibration, chemicals, sunlight, abrasion, impact, and corrosion. One side of the substrate is usually coated with an adhesive material to attach the tag to an object. The adhesive material must be able to withstand appropriate environmental conditions.

[0039] RFID tags can be classified by the RF range they use to communicate (i.e., low, high, or ultra-high), and the way the tag communicates with the reader (active or passive).

[0040] In an exemplary embodiment, the “passive” RFID tag used in the practice of the present invention measures from about 20 to about 28 mm (preferably, from about 22 to about 26 mm) in total length, and from about 10.5 to about 20.5 mm (preferably, from about 13.5 to about 17.5 mm) in total width, and incorporates an IC chip and an antenna into a substrate, the substrate being selected from the group of single or multi-layer flexible plastic or paper substrates. In another exemplary embodiment, the RFID tag is a “passive” RFID tag made using a hardened ceramic substrate.

[0041] In a preferred embodiment, the RFID tag is a passive Ultra-High Frequency (UHF) RFID tag (plastic substrate) with an adhesive backing, which operates in the about 860 megahertz (MHz) to about 960 MHz range.

[0042] The RFID tag preferably has a wide omnidirectional read range, even when covered or embedded within both the inventive housing assembly and tool handle, of at least about 30 centimeters (cm), more preferably, from about 30 to about 200 cm. The RFID tag may be read by any suitable RFID reader.

[0043] The RFID tag of the present invention is located on, but insulated from, the tang using the inventive tag housing assembly, as described in more detail below.

Housing Assembly

[0044] The present invention provides an assembly that houses or encompasses a detectable wireless tag (e.g., an RFID tag), which is suitable for use on a tool, and which comprises: an inner holder; an outer holder; and the detectable wireless tag positioned between the inner and outer holders.

[0045] The inventive housing assembly serves: to hold the tag in a desired position/location for optimal range through one or more manufacturing processes (e.g., a molding or overmolding process for producing a handle); and to protect the tag from harm resulting from its exposure to raised temperatures and pressures during the one or more manufacturing processes.

[0046] Referring now to the drawings in detail, reference numerals 10 and 100 have been used to denote a first and a second exemplary embodiment of the inventive housing assembly, respectively.

[0047] In the first exemplary embodiment 10, which is shown in FIG. 1A, the tool is a meat processing hook 12, and the housing assembly 10 comprises: an inner holder 14; an outer holder 16; and a detectable wireless tag 18 positioned between the inner and outer holders 14, 16. In this exemplary embodiment, both the inner holder 14 and the outer holder 16 are substantially conical in overall shape and have a substantially circular cross-sectional shape. The inner holder 14, which is sized to nest within the outer holder 16, has a substantially flat section 20 on its outer surface, which is sized to accommodate all or part of the tag electronics (i.e., IC chip) of the detectable wireless tag 18. When the outer holder 16 is positioned over the inner holder 14, the substantially flat section 20 of the inner holder 14 forms a gap which aides in protecting the tag electronics. The antenna portion of the tag 18 will typically extend beyond opposing longitudinal edges of the substantially flat section 20 of the inner holder 14.

[0048] As best shown in FIG. 1D, the inner holder 14 has a plurality of ribs (preferably from about 2 to about 4 ribs) 22, on its inner surface 24, which are designed to contact the projection or tang 26, of the tool. The ribs 22, allow for a secure fit between the inner holder and the tang of a tool regardless of minor variations in the size/diameter of the inner holder and/or the tang.

[0049] During assembly of the inventive housing assembly, all or part of the tag electronics are positioned over and adhered to the substantially flat section 20 of the inner holder 14. The substantially flat section 20 has the added benefit of serving as a visual aid for proper tag placement during assembly. The antenna portion of the tag 18 is then wrapped and adhered around the outer surface of the inner holder 14 on both sides of the substantially flat section 20. Hence, once applied onto tang 26 (as shown in FIG. 1B), the RFID tag 18 is positioned substantially equidistant from tang 26, wrapping around it in a circular fashion. The inventive housing assembly 10 maintains the detectable wireless tag 18 at a distance of at least about 0.5 mm (preferably, from about 1.0 to about 2.0 mm) from the tang 26 of the meat processing hook 12.

[0050] As will be readily appreciated by those skilled in the art, for less flexible tags (e.g., hardened ceramic tags) that cannot wrap around the inner holder in a circular fashion, the inner and outer holders would be adapted to accommodate the tag shape.

[0051] In the second exemplary embodiment 100, which is shown in FIG. 2A, the tool is a knife 120, and the housing assembly 100 comprises: an inner holder 140; an outer holder 160; and a detectable wireless tag 180 positioned between the inner and outer holders 140, 160. In this second exemplary embodiment, both the inner holder and the outer holder have a flattened cylindrical overall shape and a substantially oval cross-sectional shape. As shown in FIG. 2D, inner holder 140 has an inner rectangle-shaped slot 410 located at its proximal end 420 for securely receiving the tang.

[0052] Similar to the first exemplary embodiment, during assembly of the inventive housing assembly 100, all or part of the tag electronics are positioned over and adhered to the substantially flat section 200 of the inner holder 140. The antenna portion of the tag 180 is then wrapped and adhered around the outer surface of the inner holder 140 on both sides of the substantially flat section 200. Hence, once applied onto tang 260 (as shown in FIG. 2B), the RFID tag 180 is positioned substantially equidistant from tang 260. The inventive housing assembly 100 maintains the detectable wireless tag 180 at a distance of at least about 0.5 mm (preferably, from about 1.0 to about 2.0 mm) from the tang 260 of the knife 120.

[0053] Again, for less flexible tags (e.g., hardened ceramic tags) that cannot wrap around the inner holder, the inner and outer holders would be adapted to accommodate the tag shape.

[0054] In both the first and second exemplary embodiments, as shown in FIGS. 1A, 2A, the inner holder 14, 140, has a collar 28, 280, which allows the inner and outer holders to securely fit (e.g., snap-fit) together. In the first exemplary embodiment, collar 28 is located on proximal end 30, while in the second exemplary embodiment, collar 280 is located from about 24.13 to about 26.67 mm from distal end 320. When securely fit together, the outer holder 16, 160, and the inner holder 14, 140, have points of contact only around the collar region, and thus there is little or no contact between the detectable wireless tag 18, 180, and the outer holder 16, 160.

[0055] Inner holder 140 of the second exemplary embodiment, as shown in FIGS. 2A, 2B, has a section 340, which extends beyond the collar 280, and which contains a hole 360 that aligns with a hole 380 on tang 260. This allows molten plastic (during formation of handle 400, as described below) to flow in through the aligned holes, thereby strengthening coupling of the handle to the tang.

[0056] The inner holder 14, 140 and the outer holder 16, 160, of the first and second exemplary embodiments, are both made from high-temperature, RF translucent materials such as polyethylene terephthalate (PET), polypropylene (PP), polyoxymethylene (POM), polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polyamide 66P (A66), and ethylene propylene diene monomer (EPDM). The inner and outer holders may be 3D printed for low volume demands and injection molded for higher volume demands.

[0057] In the first exemplary embodiment, the inner and outer holders, 14, 16, both have a thickness ranging from about 0.74 to about 2.10 mm (preferably from about 0.77 to about 2.08 mm). The inner holder 14 has a length ranging from about 26.62 to about 26.72 mm, preferably, from about 26.62 to about 26.67 mm, an inner diameter ranging from about 4.90 to about 5.64 mm, preferably, from about 4.95 to about 5.59 mm, and an outer diameter ranging from about 6.86 to about 9.83 mm, preferably, from about 6.86 to about 9.78 mm. As will be readily appreciated by those skilled in the art, a draft angle applied to each holder will make the diameters different at the proximal and distal ends of the holder. The outer holder 16 has a length ranging from about 27.89 to about 27.99 mm, preferably, from about 27.94 to about 27.99 mm, an inner diameter ranging from about 7.77 to about 9.73 mm, preferably, from about 7.77 to about 9.68 mm, and an outer diameter ranging from about 9.35 to about 11.23 mm, preferably, from about 9.40 to about 11.18 mm.

[0058] In the second exemplary embodiment, the inner and outer holders 140, 160, both have a thickness ranging from about 0.75 to about 2.58 mm (preferably from about 0.78 to about 2.54 mm). The inner holder 140 has a length ranging from about 43.13 to about 43.23 mm, preferably, from about 43.13 to about 43.18 mm, an inner semi-minor diameter ranging from about 7.57 to about 8.18 mm, preferably, from about 7.62 to about 8.13 mm, an inner semi-major diameter ranging from about 14.96 to about 15.80 mm, preferably, from about 15.24 to about 15.75, an outer semi-minor diameter ranging from about 7.57 to about 8.18 mm, preferably, from about 7.62 to about 8.13 mm, and an outer semi-major diameter ranging from about 15.19 to about 15.80 mm, preferably, from about 15.24 to about 15.75 mm. The rectangle-shaped slot positioned inside the inner holder 140 for securely receiving the tang, has a width ranging from about 2.49 to about 2.60 mm, preferably, from about 2.49 to about 2.54 mm, and a length ranging from about 10.11 to about 10.21 mm, preferably, from about 10.11 to about 10.16 mm.

[0059] The outer holder 160 has a length ranging from about 27.38 to about 27.48 mm, preferably, from about 27.42 to about 27.48 mm, an inner semi-minor diameter ranging from about 8.08 to about 8.18 mm, preferably, from about 8.08 to about 8.13 mm, an inner semi-major diameter ranging from about 15.70 to about 15.80 mm, preferably, from about 15.70 to about 15.75 mm, an outer semi-minor diameter ranging from about 9.09 to about 9.20 mm, preferably, from about 9.14 to about 9.20 mm, and an outer semi-major diameter ranging from about 16.71 to about 16.82 mm, preferably, from about 16.76 to about 16.82 mm.

[0060] When assembled onto the tang of a tool, the antenna of the wireless tag and the tang are galvanically separated and are not electromagnetically coupled. In other words, the subject invention does not provide for the electromagnetic coupling of the antenna of the wireless tag to the tang.

Handle

[0061] Handles may be made from any suitable material including, but not limited to, plastics, metal, wood, stone, composite, synthetic, natural, and man-made materials.

[0062] In an exemplary embodiment, the tang and the housing assembly, which surrounds the tang, are overmolded with a plastics material using, for example, an injection molding (i.e., heat/pressure molding) or other forming process. Suitable plastics materials include, but are not limited to, moldable plastics such as polyethylene, polypropylene, polystyrene, and vinyl acetate. In one exemplary embodiment, the tool is a meat or meat processing hook and the moldable plastics material is a purple-colored moldable plastics material.

[0063] The first and second exemplary embodiments overmolded with a plastics material to form a handle 40, 400, are shown in FIGS. 1C and 2C.

[0064] Upon completion of the molding process, and upon cooling of the overmolded assembly to ambient temperature, Acceptance Quality Limits (AQL) testing (scan performance) is performed. The testing involves signaling the passive RFID tag (which is now embedded inside the housing assembly and the handle) and receiving an expected acknowledging signal from the RFID tag using an RFID omnidirectional scanner within a desired range of at least about 30 cm, preferably, from about 30 to about 200 cm.

[0065] In another exemplary embodiment, a handle is molded onto the housing assembly separate from the tang (e.g., injection molded) and upon cooling is attached to the tang using, for example, known hafting techniques. In one such exemplary embodiment, the inventive housing assembly is pressed, by hand, onto a tang-shaped tongue (i.e., a steel molding fixture). The tongue is held in place during the handle molding process, and then removed immediately, while hot, leaving the housing assembly and a tang-shaped hole in the handle. When hafted, the tang is slid into the hole and through the housing assembly.

[0066] Alternatively, the handle may be prepared with an elongated hollow hole at its center. The tang and housing assembly are inserted into the hollow hole and an injection molded plastic material is used to cover, surround, and hold the handle to both the tang and the housing assembly.

Method for Providing a Tool with a Detectable Wireless Tag

[0067] The present invention further provides a method for providing a tool with a detectable wireless tag, which comprises:

[0068] (a) arranging for a detectable wireless tag to be housed within an assembly; and either

[0069] (b)(1) arranging for the assembly housing the detectable wireless tag to be positioned on the projection or tang of the tool, and then arranging for either (i) a handle to be formed over and thereby encompass the assembly and the tang, or (ii) the tang with the assembly to be inserted into a hole in a pre-existing handle and then at least partially filling the hole to firmly hold in place the assembly and the tang; or

[0070] (b)(2) arranging for a handle to be formed over and thereby encompass the assembly housing the detectable wireless tag and attaching the tang to the handle and assembly using known techniques (e.g. hafting technique).

[0071] In an exemplary embodiment, the inventive method comprises: [0072] 1. moving the inner holder 14, 140 onto the projection or tang 26, 260 and tapping it into place using, for example, a rubber mallet; [0073] 2. adhering the detectable wireless tag 18, 180 onto the inner holder 14, 140 so that the tag electronics are positioned over the substantially flat section 20, 200, the tag antenna extending on either side of the substantially flat section; [0074] 3. moving and engaging (e.g., snap-fitting) the outer holder 16, 160 onto the inner holder 14, 140; and then [0075] 4. either arranging for a handle to be formed over and thereby encompass the housing assembly 10, 100 and the tang 26, 260, or arranging for the housing assembly 10, 100 and the tang 26, 260 to be inserted into a hole in a pre-existing handle and then bonded in place by at least partially filling the hole with, for example, a melt flowing adhesive.

[0076] In another exemplary embodiment, the inventive method comprises: [0077] 1. adhering the detectable wireless tag 18, 180 onto the inner holder 14, 140 so that the tag electronics are positioned over the substantially flat section 20, 200, the tag antenna extending on either side of the substantially flat section; [0078] 2. moving and engaging (e.g., snap-fitting) the outer holder 16, 160 onto the inner holder 14, 140 for form an assembly; [0079] 3. arranging for a handle to be formed over and thereby encompass the assembly; and [0080] 4. attaching the tang to the handle and assembly using, for example, a hafting technique.

Method for Monitoring (Tracking and Tracing) Tools Used within a Packaging Facility

[0081] The present invention also provides a method for monitoring (tracking and tracing) tools used within a packaging facility (e.g., a meat, poultry or fish packaging facility), which method comprises: using the inventive housing assembly with tools used within the packaging facility to track and trace each tool within the facility. By use of the inventive monitoring method, each tool's real-time location may be determined and the maintenance of cleanliness and sanitation standards for each tool ensured. The inventive method may also be used to determine the real-time condition of each tool and to use this information to manage the training/competency of the users, with a goal toward reducing repetitive motion injuries.

[0082] Although exemplary embodiments have been shown and described, it will be clear to those of ordinary skill in the art that a number of changes, modifications, or alterations to the invention as described can be made. All such changes, modifications, and alternations should therefore be seen as within the scope of the disclosure.
