Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit under Articles 4 and 8 of the Stockholm Act for the Protection of Industrial Property of U.S. Provisional Patent Application No. 62 / 907,758, filed on September 30, 2019, which is incorporated herein by reference in its entirety. Technical Field

[0003] The present invention relates to a connection checker for a clamp, and more particularly, to a clamp or connector including a radio frequency identification (RFID) tag that indicates the state of the clamp or connection through wireless transmission. Background Art

[0004] A clamp is a fastening device used to hold or secure objects together tightly to prevent movement or separation by applying inward pressure. There are many types of clamps that can be used for many different purposes. Some are temporary and are used to position parts while holding them together, others are permanent.

[0005] One type of clamp is called a hose clamp or hose clip or hose lock, which is a device used to attach and seal a hose to a fitting such as a barb or a fitting. Some types of hose clamps include screw / strap (worm gear) clamps, spring clamps, wire clamps, ear clamps, v-clamps, etc. Typically, hose clamps are used to connect hoses or lines to fittings that carry toxic substances (such as refrigerants, fuel, oil, coolants, etc.) and are therefore critical components. Therefore, it is important that the clamp or connector is properly secured, thereby properly securing the connection (i.e., hose / fitting connection).

[0006] It should be understood that clamps or connectors are key components of many other connectors, and their use extends beyond just fluid connections. For example, clamps can be used in the medical field to secure various tools or parts of machines during surgical or non-surgical procedures. Clamps or connectors can be used to secure moving objects together, such as securing a trailer to a vehicle.

[0007] Therefore, there has long been a need for a connection tester that ensures that a connection, connector or clamp is adequately secured. There has also long been a need for a connection tester that utilizes RFID to ensure that connections between various components are securely connected. Summary of the invention

[0025] First, it should be understood that like reference numerals in different figures indicate like or functionally similar structural elements. It should be understood that the claims are not limited to the disclosed aspects.

[0026] Furthermore, it is to be understood that the present disclosure is not limited to the specific methods, materials and modifications described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to limit the scope of the claims.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. It should be understood that any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the exemplary embodiments. The components of the present invention can be driven by hydraulics, electronics, pneumatics and / or springs.

[0028] It should be understood that the term "substantially" is synonymous with terms such as "close", "very close", "approximately", "around", "near", "close to", "roughly", "adjacent", "nearby", etc., and these terms can be used interchangeably in the specification and claims. It should be understood that the term "nearby" is synonymous with terms such as "near", "close", "adjacent", "near", "immediately adjacent", "adjacent", etc., and these terms can be used interchangeably in the specification and claims. The term "approximately" refers to a value within ten percent of a specified value.

[0029] It should be understood that, unless otherwise stated, the use of "or" in this application is relative to a "non-exclusive" arrangement. For example, when it is said that "item x is A or B", it can be understood that this can mean one of the following: (1) item x is only one or the other of A and B; (2) item x is both A and B. In other words, the word "or" is not used to define an "exclusive or" arrangement. For example, an "exclusive or" arrangement stating "item x is A or B" would require that x can only be one of A and B. In addition, as used herein, "and / or" is intended to represent a grammatical conjunction used to indicate that one or more elements or conditions described may be included or appear. For example, a device comprising a first element, a second element, and / or a third element is intended to be interpreted as any of the following structural arrangements: a device comprising a first element; a device comprising a second element; a device comprising a third element; a device comprising a first element and a second element; a device comprising a first element and a third element; a device comprising a first element, a second element, and a third element; or, a device comprising a second element and a third element.

[0030] In addition, as used herein, the phrase "at least one of..." in conjunction with a system or element is intended to indicate that the system or element includes one or more elements listed after the phrase. For example, a device includes at least one of: a first element; a second element; a third element, and is intended to be interpreted as any of the following structural arrangements: a device including the first element; a device including the second element; a device including the third element; a device including the first element and the second element; a device including the first element and the third element; a device including the first element, the second element, and the third element; or, a device including the second element and the third element. When the phrase "at least one of..." is used herein, a similar interpretation is intended. In addition, as used herein, "and / or" is intended to represent a grammatical conjunction used to indicate that one or more elements or conditions described may be included or occur. For example, a device comprising a first element, a second element and / or a third element is intended to be interpreted as any of the following structural arrangements: a device comprising the first element; a device comprising the second element; a device comprising the third element; a device comprising the first element and the second element; a device comprising the first element and the third element; a device comprising the first element, the second element and the third element; or, a device comprising the second element and the third element.

[0031] Now pay attention to the attached figure, Figure 1 is a perspective view of the RFID connector 10 in an unlocked state. Figure 2 is a perspective view of the RFID connector 10 in a locked state. Figure 3 It is roughly along Figure 1Detailed view of RFID connector 10 taken from detail 3 in FIG. RFID connector 10 generally includes a connector or fixture 20 and an RFID assembly 60, 160, 260. Figure 1-3 Let's read the description below.

[0032] The connector 20 includes a component or outer ring or band 22 and a component or inner ring 40. Component 22 includes an outwardly facing surface, such as a radially outwardly facing surface 24, an inwardly facing surface, such as a radially inwardly facing surface 26, an end 28, and an end 30. In some embodiments, the end 28 and the end 30 are operably arranged to be displaced toward each other so as to reduce the diameter of the connector 20 and to squeeze or clamp the components together (e.g., the ends of two pipes, tubes, or pipelines). In some embodiments, as shown, the end 28 includes a ring and is connected to a component or trunnion, such as a slotted trunnion 32, and the end 30 includes a ring and is connected to a component or trunnion, such as a threaded trunnion 34. The screw 36 engages the trunnion 32 and the trunnion 34 and is operably arranged to displace the trunnion 34 toward and away from the trunnion 32 (or is operably arranged to displace the trunnion 32 toward and away from the trunnion 34). In some embodiments, the screw 36 is threaded and extends through a slot or through hole in the trunnion 32 and threadedly engages the threaded trunnion 34. When the screw 36 is rotated in a first direction, the threaded trunnion 34 is displaced toward the slotted trunnion 32 (or the slotted trunnion 32 is displaced toward the threaded trunnion 34). When the screw 36 is rotated in a second direction opposite to the first direction, the threaded trunnion 34 is displaced away from the slotted trunnion 32 (or the slotted trunnion 32 is displaced away from the threaded trunnion 34). In some embodiments, the trunnion 32 is threaded and the trunnion 34 is slotted.

[0033] Component 40 is connected to component 22 and arranged (radially) inward from component 22. In some embodiments, as shown, component 40 includes one or more segments, such as segments 46A-C. In some embodiments, connector 40 includes only one segment, such as segment 46A. In some embodiments, connector 20 does not include a connector or inner ring, and only includes connector (i.e. outer ring) 22. Segments 46A-C are connected to radially inward surface 26 and are spaced apart circumferentially therearound. Each segment 46A-C includes an outwardly facing surface, such as a radially outwardly facing surface 42 connected to the radially inwardly facing surface 26, and an inwardly facing surface, such as a radially inwardly facing surface 44. The radially inwardly facing surface 44 can be linear (e.g., cylindrical) or curvilinear (e.g., U-shaped) so that the two components are clamped or fixed together. For example, as shown, the radially inwardly facing surface 44 is U-shaped so that the two pipe ends with flanges can be fixed within the profile of the radially inwardly facing surface 44. However, it should be understood that any fixture or connector can be used instead of connector 20, and the present disclosure should not be limited to the contents shown in the accompanying drawings.

[0034] RFID assembly 60, 160, 260 is disposed on a radially outwardly facing surface of one or more segments, such as radially outwardly facing surface 42 of segment 46A. RFID assembly 60, 160, 260 includes at least one contact electrically connected to component 22, as will be described in more detail below. In some embodiments, RFID assemblies 60 and 160 include contacts 80A-B and 180A-B, respectively. Figure 3 As best shown, the contacts 80B, 180B are electrically connected to the radially outwardly facing surface 42 of the segment 46A of the component 40. Since the segment 46A is also electrically connected to the component 22, the contacts 80B, 180B are electrically connected to the component 22. The contacts 80A, 180A are not electrically connected to the radially outwardly facing surface 42 of the segment 46A. As shown, the contacts 80A, 180A are arranged on the insulating layer 62, 162, thereby preventing electrical connection between the contacts 80A, 180A and the segment 46A and thus the element 22, which will be described in more detail below. When the component 22 is tightened (i.e., the end 28 is displaced closer to the end 30), the radially inwardly facing surface 26 of the component 22 contacts and electrically connects to the contacts 80A, 180A, thereby completing the circuit between the contacts 80A, 180A and 80B, 180B. Once the circuit is completed, the RFID tag 70, 170 indicates that the connection is secure.

[0035] Figure 4 6 is a perspective view of an RFID assembly 60. The RFID assembly 60 generally includes at least one layer (e.g., layer 62), an RFID tag 70, and at least one contact (e.g., contact 80A and / or contact 80B). In some embodiments, the RFID assembly 60 is an RFID tag connected to a first component of a connector, wherein the connector is arranged to connect two components. It should be understood that the RFID assembly 60 can be used to ensure any type of connection, such as a fluid connection, a constant velocity (CV) joint, a trailer hitch connection, an electrical connection, etc. It should be understood according to Figure 1-4 Let's read the description below.

[0036] Layer 62 includes surface 64 and surface 66, and is operably arranged to be secured to a component of connector 20, such as radially outwardly facing surface 42 of component 40. In some embodiments, surface 64 includes an adhesive and secures RFID tag 70 and / or contact 80A to connector 20 (e.g., segment 46A). It should be understood that layer 62 need not be attached to connector 20 via an adhesive, but rather may be attached and / or applied using any other suitable means, such as string, tape, hook and loop fasteners, solder, welding, etc. In some embodiments, layer 62 is an insulator. As shown in FIG. Figure 1 and 3As shown, in the unconnected state, contact 80A is not electrically connected to segment 46A and component 22 , while contact 80B is electrically connected to segment 46A and component 22 .

[0037] RFID assembly 60 may also include an additional ferrite layer connected to top surface 66 (not shown), which is operably arranged as a platform or substrate for RFID tag 70 and / or contacts 80A. In some embodiments, RFID assembly 60 also includes layer 68. Layer 68 is operably arranged to cover and protect RFID tag 70. Figure 4 As shown, layer 68 completely covers RFID tag 70 and at least partially covers contact 80A. However, it is desired that at least a portion of contact 80A be exposed, such as exposed portion 82, so that it can engage and electrically connect to end 28 of component 22, as will be described in more detail below.

[0038] RFID tag 70 is arranged on surface 66 and includes integrated circuit (IC) or chip 72 and antenna 74. In some embodiments, RFID tag 70 includes passive RFID tag. In some embodiments, RFID tag 70 includes active RFID tag (and also includes power source). In some embodiments, RFID tag 70 includes semi-passive RFID tag. In some embodiments, RFID tag 70 is preprogrammed so that it transmits information, such as unique identification (UID) number, state of RFID component 60 (i.e., open or closed), etc. Antenna 74 is connected to IC72 at antenna radio frequency (RF) input terminal LA at the first end and to IC72 at antenna RF input terminal LB at the second end via conductors 76A and 76B, respectively. RFID tag 70 is further connected to contact 80A and contact 80B. Specifically, conductor 78A connects contact 80A to IC72 at ground pin GND, and conductor 78B connects contact 80B to IC72 at detector pin DP.

[0039] Contact 80A is separated from contact 80B. Specifically, contact 80A is arranged on surface 66 of layer 62, while contact 80B is not arranged on layer 62. Contact 80B is arranged on radially outwardly facing surface 42 and is electrically connected to component 40 and component 22 of connector 20. In some embodiments, contact 80B is arranged on radially inwardly facing surface 26 and is electrically connected to component 40 and component 22 of connector 20. It should be understood that contact 80B can be connected to component 40 and / or component 22 by any suitable means, such as adhesive, string, tape, hook and loop fasteners, solder, welding, etc. In some embodiments, contacts 80A and 80B are electrical conductors. It should be understood that as Figure 1 and 3As shown, in the unlocked state, the contact 80B is always electrically connected to the component 22, while the contact 80A is not electrically connected to the component 22. When the connector 20 is properly secured, the end 28 of the component 22 is pulled into engagement and electrical connection with the contact 80A. In some embodiments, the component 22 and / or the component 40 includes a conductive material (e.g., metal). Thus, when the end 28 engages with the contact 80A, the component 22 completes the circuit between the contacts 80A-B and the IC 72, and enables the RFID tag 70 to be enabled (i.e., the RFID tag 70 can be powered by an electromagnetic field generated by an external device (not shown)) or switched to a closed state (from an open state). Before the circuit is completed, i.e., before the contact 80A is directly electrically connected to the contact 80B, the RFID tag 70 is not enabled (i.e., the RFID tag 70 cannot be powered by an electromagnetic field generated by an external device), or in some embodiments, it indicates a closed state. When the circuit is completed (i.e., as shown in FIG. 2 ), the RFID tag 70 is not enabled (i.e., the RFID tag 70 cannot be powered by an electromagnetic field generated by an external device). Figure 2 As shown, component 22 and / or component 40 are directly connected to contact 80A and contact 80B), an external device such as an RFID reader will detect that the RFID tag 70 is enabled, or is in a closed state, thereby indicating that the RFID connector 10 is properly connected. In other words, when the RFID tag 70 is enabled, the RFID reader will recognize that the RFID tag 70 exists, thereby determining that the RFID connector 10 is properly connected. When the circuit is not completed (i.e., contact 80A is not directly connected to contact 80B), the RFID reader will not detect the enabled RFID tag 70, thereby indicating that the RFID connector 10 is not properly connected. In other words, when the RFID tag 70 is disabled, the RFID reader will not recognize that the RFID tag 70 exists, thereby determining that the RFID connector 10 is not properly connected.

[0040] In some embodiments, regardless of whether contacts 80A and 80B are connected, RFID tag 70 is always enabled and can be detected and read by an RFID reader. In such an embodiment, when contacts 80A and 80B are not directly connected, such as through component 22 and / or component 40, RFID tag 70 is able to send certain information to the RFID reader. Such information may include, but is not limited to, a UID number (e.g., for RFID tags, connector form, etc.), a size number, a model number, a serial number, a state of the RFID tag 70 (i.e., open or closed), a uniform resource locator (URL), a station identifier (i.e., a manufacturing batch number), a date / time stamp, a description, etc. In other words, regardless of whether contacts 80A and 80B are connected, RFID tag 70 will always send certain data (e.g., UID number, state, etc.), provided that it is functioning properly. Therefore, RFID tag 70 is preprogrammed to always send at least a UID number and a state (i.e., open or closed), such as using hexadecimal data or values. This is important because it allows a user to scan a given RFID tag to determine whether it is functioning properly (i.e., if the RFID tag is transmitting data properly, then it is functioning properly) as well as to determine its current state (i.e., open or closed). When contacts 80A and 80B are connected, for example, via component 22 and / or component 40, the RFID tag 70 transmits data indicating a closed state. In some embodiments, the RFID tag 70 indicates a first value (e.g., a first hexadecimal value) for an open state and a second value (e.g., a second hexadecimal value) for a closed state, the second value being different from the first value. It should be understood that the RFID tag 70 may include any programming suitable for indicating its proper functioning, as well as the distinction between an open state and a closed state, and that the present disclosure should not be limited to the use of a hexadecimal system.

[0041] Figure 5 is a perspective view of RFID assembly 160 . Figure 6 It is roughly along Figure 5 6-6 in FIG. 1 . RFID assembly 160 generally includes at least one layer (e.g., layer 162), RFID tag 170, and at least one contact (e.g., contact 180A and / or contact 180B). In some embodiments, RFID assembly 160 is an RFID tag connected to a first component of a connector, wherein the connector is arranged to connect two components. It should be understood that RFID assembly 160 can be used to ensure any type of connection, such as a fluid connection, a CV joint, a trailer hitch connection, an electrical connection, etc. It should be understood that the RFID assembly 160 can be used to ensure any type of connection, such as a fluid connection, a CV joint, a trailer hitch connection, an electrical connection, etc. Figure 1-6 Let's read the description below.

[0042] Layer 162 includes surface 164 and surface 166 and is operably arranged to be secured to a component of connector 20, such as radially outwardly facing surface 42 of component 40 (e.g., segment 46A). In some embodiments, surface 164 includes an adhesive and secures RFID tag 170 and / or contacts 180A and / or contacts 180B to connector 20. It should be understood that layer 162 need not be attached to connector 20 via an adhesive, but rather may be attached and / or applied using any other suitable means, such as string, tape, hook and loop fasteners, solder, welding, etc. In some embodiments, layer 162 is an insulator. As shown in FIG. Figure 1 and 3 As shown, in the unconnected state, contact 180A is not electrically connected to segment 46A and component 22 , while contact 180B is electrically connected to segment 46A and component 22 .

[0043] RFID assembly 160 may also include an additional ferrite layer connected to top surface 166 (not shown), which is operably arranged as a platform or substrate for RFID tag 170 and / or contacts 180A. In some embodiments, RFID assembly 160 also includes layer 168. Layer 168 is operably arranged to cover and protect RFID tag 170 and / or contacts 180A. Figure 5-6 As shown, layer 168 completely covers RFID tag 170 and at least partially covers contact 180A. However, it is desired that at least a portion of contact 180A be exposed, such as exposed portion 182, so that it can engage and electrically connect to end 28 of component 22, as will be described in more detail below.

[0044] RFID tag 170 is arranged on surface 166 and includes IC or chip 172 and antenna 174. In some embodiments, RFID tag 170 includes a passive RFID tag. In some embodiments, RFID tag 170 includes an active RFID tag (and also includes a power supply). In some embodiments, RFID tag 170 includes a semi-passive RFID tag. In some embodiments, RFID tag 170 is preprogrammed so that it transmits information, such as UID number, the state of RFID component 160 (i.e., open or closed), etc. Antenna 174 is connected to IC172 at antenna RF input terminal LA at a first end and to IC172 at antenna RF input terminal LB at a second end via conductors 176A and 176B, respectively. RFID tag 170 is further connected to contact 180A and contact 180B. Specifically, conductor 178A connects contact 180A to IC172 at ground pin GND, and conductor 178B connects contact 180B to IC172 at detector pin DP.

[0045] Contact 180A is separate from contact 180B. Specifically, contact 180A is disposed on surface 166 of layer 162 and contact 180B is disposed on surface 164 of layer 162. Contact 180B is disposed on radially outwardly facing surface 42 and is electrically connected to component 40 and component 22 of connector 20. In some embodiments, contacts 180A and 180B are electrical conductors. It should be understood that, as Figure 1 and 3 As shown, in the unlocked state, contact 180B is always electrically connected to component 22 (via segment 46A), while contact 180A is not electrically connected to component 22. When connector 20 is properly secured, end 28 of component 22 is pulled into engagement and electrical connection with contact 180A. In some embodiments, component 22 and / or component 40 include a conductive material (e.g., metal). In this way, component 22 completes the circuit between contacts 180A-B and IC 172 and enables RFID tag 170 to be enabled (i.e., RFID tag 170 can be powered by an electromagnetic field generated by an external device (not shown)) or switched to a closed state (from an open state). Before the circuit is completed, i.e., before contact 180A is directly electrically connected to contact 180B, RFID tag 170 is not enabled (i.e., RFID tag 170 cannot be powered by an electromagnetic field generated by an external device), or in some embodiments, it indicates an open state. When the circuit is completed (i.e., as shown in FIG. 1 ), RFID tag 170 is not enabled (i.e., RFID tag 170 cannot be powered by an electromagnetic field generated by an external device), or in some embodiments, it indicates an open state. Figure 2 As shown, component 22 and / or component 40 are directly connected to contact 180A and contact 180B), an external device such as an RFID reader will detect that RFID tag 170 is enabled, or is in a closed state, thereby indicating that RFID connector 10 is properly connected. In other words, when RFID tag 170 is enabled, the RFID reader will recognize that RFID tag 170 exists, thereby determining that RFID connector 10 is properly connected. When the circuit is not completed (i.e., contact 180A is not directly connected to contact 180B), the RFID reader will not detect the enabled RFID tag 170, thereby indicating that RFID connector 10 is not properly connected. In other words, when RFID tag 170 is disabled, the RFID reader will not recognize that RFID tag 170 exists, thereby determining that RFID connector 10 is not properly connected.

[0046] In some embodiments, regardless of whether contacts 180A and 180B are connected, RFID tag 170 is always enabled and can be detected and read by an RFID reader. In such an embodiment, when contacts 180A and 180B are not directly connected, such as through component 22 and / or component 40, RFID tag 170 is able to send certain information to the RFID reader. Such information may include, but is not limited to, a UID number (e.g., for an RFID tag, connector, etc.), a size number, a model number, a serial number, a state of RFID tag 170 (i.e., open or closed), a URL, a site identifier (i.e., a manufacturing batch number), a date / time stamp, a description, etc. In other words, regardless of whether contacts 180A and 180B are connected, RFID tag 170 will always send certain data (e.g., UID number, state, etc.), provided that it is functioning properly. Therefore, RFID tag 170 is preprogrammed to always send at least a UID number and a state (i.e., open or closed), such as using hexadecimal data or values. This is important because it allows a user to scan a given RFID tag to determine whether it is functioning properly (i.e., if the RFID tag is transmitting data properly, then it is functioning properly) as well as to determine its current state (i.e., open or closed). When contacts 180A and 180B are connected, for example, via component 22 and / or component 40, the RFID tag 170 transmits data indicating a closed state. In some embodiments, the RFID tag 170 indicates a first value (e.g., a first hexadecimal value) for an open state and a second value (e.g., a second hexadecimal value) for a closed state, the second value being different from the first value. It should be understood that the RFID tag 170 may include any programming suitable for indicating its proper functioning, as well as the distinction between an open state and a closed state, and that the present disclosure should not be limited to the use of a hexadecimal system.

[0047] Figure 7 is a perspective view of RFID assembly 260 . Figure 8 It is roughly along Figure 1 Detailed view of RFID connector 10 as captured in detail 8 of FIG. RFID assembly 260 generally includes at least one layer (e.g., layer 262), RFID tag 270, and at least one contact (e.g., contact 280). In some embodiments, RFID assembly 260 is an RFID tag connected to a connector or fixture, wherein the connector or fixture is arranged to connect two elements together. It should be understood that RFID assembly 260 can be used to ensure any type of connection, such as a fluid connection, a CV joint, a trailer hitch connection, an electrical connection, etc. Figure 1-3 and 7-9B to read the following description.

[0048] Layer 262 includes surface 264 and surface 266, and is operably arranged to be secured to a component of connector 20, such as radially outwardly facing surface 42 (e.g., segment 46A) of component 40. In some embodiments, surface 264 includes an adhesive and secures RFID tag 270 and / or contact 280 to connector 20. It should be understood that layer 262 need not be connected to connector 20 by an adhesive, but rather may be connected and / or applied using any other suitable means, such as string, tape, hook and loop fasteners, solder, welding, etc. In some embodiments, layer 262 is an insulator.

[0049] RFID assembly 260 may also include an additional ferrite layer connected to top surface 266 (not shown), which is operably arranged as a platform or substrate for RFID tag 270 and / or contacts 280. In some embodiments, RFID assembly 260 also includes layer 268. Layer 268 is operably arranged to cover and protect RFID tag 270 and / or contacts 280. Figure 7 As shown, layer 268 completely covers RFID tag 270 and at least partially covers contact 280. However, it is desired that at least a portion of contact 280 be exposed, such as exposed portion 282, so that it can engage and electrically connect to end 28 of component 22, as will be described in more detail below.

[0050] RFID tag 270 is arranged on surface 266 and includes IC or chip 272 and antenna 274. In some embodiments, RFID tag 270 includes a passive RFID tag. In some embodiments, RFID tag 270 includes an active RFID tag (and also includes a power supply). In some embodiments, RFID tag 270 includes a semi-passive RFID tag. In some embodiments, RFID tag 270 is preprogrammed so that it transmits information, such as UID number, the state of RFID component 260 (i.e., open or closed), etc. Antenna 274 is connected to IC272 at antenna RF input terminal LA at a first end and to IC272 at antenna RF input terminal LB at a second end via conductors 276A and 276B, respectively. RFID tag 270 is further connected to contact 280. Specifically, conductor 278A connects contact 280 to IC272 at ground pin GND, and conductor 278B connects contact 280 to IC272 at detector pin DP.

[0051] The contact 280 is arranged on the surface 266 of the layer 262. The contact 280 is arranged on the radially outwardly facing surface 42. The contact 280 is operably arranged to engage with the component 22, such as the end 28. In some embodiments, the contact 280 is a pressure-sensitive contact. When the RFID connector 10 is properly connected, the end 28 engages the contact 280 and applies pressure thereto. In some embodiments, the connector 20 includes metal. In some embodiments, the connector 20 includes a non-metallic material, such as a polymer or an elastomer. It should be understood that the connector 20 may include any material suitable for applying pressure to the contact 280. Once sufficient pressure is applied to the contact 280, the circuit between the conductors 278A and 278B and the IC 272 is completed, and the RFID tag 270 is enabled (i.e., the RFID tag 270 can be powered by an electromagnetic field generated by an external device (not shown)) or indicates a closed state. Before the circuit is completed, i.e., before the ends of conductors 278A and 278B are electrically connected, RFID tag 270 is not enabled (i.e., RFID tag 270 cannot be powered by an electromagnetic field generated by an external device) or indicates an open state. When the circuit is completed (i.e., connector 20 applies sufficient pressure to contact 280 to directly electrically connect conductor 278A to conductor 278B), an external device such as an RFID reader will detect that RFID tag 270 is enabled or in a closed state, thereby indicating that RFID connector 10 is properly connected. In other words, when RFID tag 270 is enabled, an RFID reader will recognize that RFID tag 270 is present, thereby determining that RFID connector 10 is properly connected. When the circuit is not completed (i.e., the end of conductor 278A is not directly connected to contact 278B), an RFID reader will not detect an enabled RFID tag 270, thereby indicating that RFID connector 10 is not properly connected. In other words, when RFID tag 270 is disabled, an RFID reader will not recognize that RFID tag 270 is present, thereby determining that RFID connector 10 is not properly connected.

[0052] In some embodiments, regardless of whether the conductive layers 290 and 294 (i.e., conductors 278A and 278B) are in direct contact, the RFID tag 270 is always enabled and can be detected and read by the RFID reader. In such an embodiment, and as previously described, when the conductive layers 290 and 294 (i.e., conductors 278A and 278B) are not directly connected, for example due to the force of component 22, the RFID tag 270 is able to send specific information to the RFID reader. This information may include, but is not limited to, a UID number, a size number, a model number, a serial number, the state of the RFID tag 270 (i.e., open or closed), a URL, a site identifier, a date / time stamp, a description, and the like. In other words, regardless of whether the conductive layers 290 and 294 (i.e., conductors 278A and 278B) are connected, the RFID tag 270 will always transmit data (e.g., UID number, state, etc.), provided that it is working properly. Therefore, the RFID tag 270 is preprogrammed to always send at least the UID number and state (i.e., open or closed), for example using hexadecimal data or values. This is important because it allows a user to scan a given RFID tag to determine whether it is functioning properly (i.e., if the RFID tag is transmitting data properly, then it is functioning properly) as well as to determine its current state (i.e., open or closed). When the conductive layers 290 and 294 (i.e., conductors 278A and 278B) are connected, for example by applying a suitable force F to layer 294 via component 22 (e.g., end 28), the RFID tag 270 transmits data indicating a closed state. In some embodiments, the RFID tag 270 indicates a first value (e.g., a first hexadecimal value) for an open state and a second value (e.g., a second hexadecimal value) for a closed state, the second value being different from the first value. It should be understood that the RFID tag 270 may include any programming suitable for indicating its normal operation and the distinction between an open state and a closed state, and the present disclosure should not be limited to the use of a hexadecimal system.

[0053] Fig.9A2 is a schematic diagram of a portion of an RFID assembly 260 in a disconnected (or disabled) state according to some embodiments of the present disclosure. It should be understood that this is merely one embodiment of a pressure-sensitive contact, and various other pressure-sensitive contacts known in the art or developed in the future may be used. Contact 280 includes a conductive layer 290, an insulating layer 292, and a conductive layer 294. Conductive layer 290 is disposed on surface 266 of layer 262. In some embodiments, conductive layer 290 is disposed on an additional ferrite layer (which is disposed on surface 266 (not shown)). In some embodiments, conductive layer 290 is disposed on radially outwardly facing surface 42 of segment 46A (i.e., excluding layer 262). Insulating layer 292 is disposed on top of layer 290. Conductive layer 294 is disposed on top of insulating layer 292. Insulating layer 292 is operably arranged to separate conductive layers 290 and 294 until sufficient force F is applied to conductive layer 294, which will be described in more detail below. Conductor 278A connects the ground pin GND to the conductive layer 294, and conductor 278B connects the detection pin DP to the conductive layer 290. In some embodiments, conductor 278A connects the ground pin GND to the conductive layer 290, and conductor 278B connects the detection pin DP to the conductive layer 294. Fig.9A As shown, conductors 278A and 278B remain unconnected, so the RFID tag 270 will indicate a disconnected state or remain disabled (i.e., the RFID reader will not detect the presence of the RFID tag 270). Therefore, in either case, the RFID reader will indicate that the RFID connector 10 is not properly secured.

[0054] Fig. 9B yes Fig.9A The RFID assembly 260 shown is a partial cross-sectional schematic diagram in a closed (or enabled) state. When a sufficient force F is applied to the conductive layer 294, for example, by component 22, the conductive layer 294 is displaced through the insulating layer 292 and contacts the conductive layer 290. When the conductive layer 294 contacts the conductive layer 290, the conductors 278A and 278B are electrically connected to complete the circuit, and the RFID tag 270 indicates a closed state or is enabled (i.e., the RFID tag 270 can be powered by the electromagnetic field generated by the RFID reader). Therefore, in either case, the RFID reader will indicate that the RFID connector 10 is properly secured. As can be seen from the figure, when the end 28 is displaced toward the end 30, the end 28 is pressed downward onto the RFID assembly 260 and a force F is applied to the contact 280, especially the layer 294.

[0055] It should be understood that the RFID tags and components described herein, such as RFID tags 70, 170 and 270 and RFID components 60, 160 and 260, can utilize any suitable radio frequency range. In some embodiments, RFID tags 70, 170 and 270 include low frequency (LF) RFID tags operating in the range of 30KHz to 300KHz and have a read range of up to 10cm. Although LFRFID tags have a shorter read range and slower data read rate than other technologies, they perform better in the presence of metal or liquid (which may interfere with other types of RFID tag transmissions). Common standards for LF RFID include ISO14223 and ISO / IEC 18000-2. In some embodiments, RFID tags 70, 170 and 270 include high frequency (HF) RFID tags operating in the range of 3MHz to 30MHz and provide a read distance of 10cm to 1m. In such embodiments, RFID tags 70, 170 and 270 can even be near field communication (NFC) tags, because NFC technology is based on HF RFID. Common standards for high frequency RFID include ISO 15693, ECMA-340, ISO / IEC 18092 (for NFC), ISO / IEC 14443A and ISO / IEC14443 (for MIFARE and other smart card solutions). In some embodiments, the RFID tags 70, 170 and 270 include ultra-high frequency (UHF) RFIDs operating in the range of 300 MHz to 2 GHz and providing a read distance of up to 12 m. A well-known standard for UHF RFID is EPCglobal Gen2 / ISO 18000-6C. In addition, in some embodiments, a single RFID reader is capable of detecting and receiving data from multiple RFID tags, not just one.

[0056] It should be understood that the above disclosed aspects and other features and functions or their alternatives can be ideally combined into many other different systems or applications.
