Description

RADIO FREQUENCY IDENTIFICATION CONNECTOR neoznn / zznz / E / YiAi Field of Invention The present description relates to a connection checker for a clamp and, more particularly, to a clamp or connector comprising a radio frequency identification (RFID) tag that indicates the status of the clamp or a connection by means of a wireless transmission. Background of the Invention A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation by applying inward pressure. Many types of clamps are available for various purposes. Some are temporary, used to position components while they are being assembled, while others are intended for permanent use. A type of clamp, known as a hose clamp, hose clip, or hose lock, is a device used to couple and seal a hose to a fitting such as a valve or nozzle. Some types of hose clamps include screw / band (worm gear) clamps, spring clamps, wire clamps, ear clamps, and other clamps. Ref. 331704 Hose clamps are frequently used to connect hoses or lines to fittings that carry toxic substances, such as coolant, fuel, oil, refrigerant, etc., and are therefore a crucial component. As such, it is essential that the clamp or connector is properly secured to ensure a secure connection (in this case, the hose / fitting connection). It should be noted that clamps or connectors are crucial components of many other connectors, and their use extends far beyond fluid connections. For example, clamps can be used in the medical field to secure components of various tools or machines during surgical or non-surgical procedures. Clamps or connectors can also be used to secure moving objects together, such as a trailer to a vehicle. As such, there has been a long-standing need for a connection verifier that ensures a connection, connector, or clamp is properly secured. There has also been a long-standing need for a connection verifier that uses RFID to guarantee a connection between multiple components is securely connected.

For example, a device comprising a first element, a second element, and / or a third element is intended to be constructed 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 and a second element; a device comprising a first and a third element; a device comprising a first, a second, and a third element; or a device comprising a second and a third element. Now, with reference to the Figures, Figure 1 is a perspective view of RFID connector 10 in an unlocked state. Figure 2 is a perspective view of RFID connector 10 in a locked state. Figure 3 is a detailed view of RFID connector 10, generally taken along detail 3 in Figure 1. RFID connector 10 generally comprises connector or clamp 20 and RFID assemblies 60, 160, and 260. The following description should be read in light of Figures 1–3. The connector 20 comprises the outer component or ring or band 22 and the inner component or ring 40. The component 22 comprises an outward-facing surface, for example, the radially outward-facing surface 24, an inward-facing surface, for example, the radially inward-facing surface 26, end 28, and end 30. In some embodiments, end 28 and end 30 are operatively arranged to be offset toward each other in order to decrease the diameter of the connector 20 and to clamp or press components together (for example, the ends of two pipes, tubes, or lines). In some embodiments, and as shown, end 28 comprises a loop and is connected to a component or trunnion, for example, a grooved trunnion 32, and end 30 comprises a loop and is connected to a component or trunnion, for example, a threaded trunnion 34.Screw 36 engages trunnion 32 and trunnion 34 and is operatively arranged to move trunnion 34 toward it and away from trunnion 32 (or operatively arranged to move trunnion 32 toward and away from trunnion 34). In some embodiments, screw 36 is threaded and extends through a slot or through-hole in trunnion 32 and engages threaded into the threaded trunnion 34. As screw 36 rotates in a first direction, the threaded trunnion 34 moves toward the slotted trunnion 32 (or the slotted trunnion 32 moves toward the threaded trunnion 34). As screw 36 is turned in a second direction, opposite to the first direction, the threaded journal 34 moves away from the slotted journal 32 (or the slotted journal 32 moves away from the threaded journal 34). In some embodiments, the journal 32 is threaded and the journal 34 is slotted. Component 40 is connected to and arranged (radially) inwardly on component 22. In some embodiments, as shown, component 40 comprises one or more segments, for example, segments 46A-46C. In some embodiments, component 40 comprises only one segment, for example, segment 46A. In some embodiments, component 20 does not comprise a connector or an inner ring, and comprises only a connector (in this case, an outer ring) 22. Segments 46A-46C are connected to the radially inwardly oriented surface 26 and are circumferentially spaced around it. neoznn / zznz / E / YiAi Each of segments 46A-46C comprises an outward-facing surface, for example, the radially outward-facing surface 42, which is connected to the radially inward-facing surface 26, and an inward-facing surface, for example, the radially inward-facing surface 44. The radially inward-facing surface 44 can be linear (for example, cylindrical) or curvilinear (for example, U-shaped) for clamping or securing two components together. For example, as shown, the radially inward-facing surface 44 is U-shaped, so that two pipe ends having flanges can be secured within the contour of the radially inward-facing surface 44. However, it should be appreciated that any clamp or connector can be used in place of connector 20, and that the present description should not be limited only to what is shown in the figures. The RFID assembly 60, 160, 260 is disposed on a radially outward-facing surface of one or more segments, for example, on the radially outward-facing surface 42 of segment 46A. The RFID assembly 60, 160, 260 comprises at least one contact that is electrically connected to component 22, as will be described in more detail below. In some embodiments, the RFID assemblies 60 and 160 comprise contacts 80A-80B and 180A-180B, respectively. As best shown in the In Figure 3, contact 80B, 180B is electrically connected to the outward-facing radial surface 42 of segment 46A of component 40. Since segment 46A is also electrically connected to component 22, it follows that contact 80B, 180B is electrically connected to component 22. Contact 80A, 180A is not electrically connected to the outward-facing radial surface 42 of segment 46A. As shown, contact 80A, 180A is positioned on insulating layer 62, 162, thereby preventing electrical connection between contact 80A, 180A and segment 46A, and thus component 22, as will be described in more detail below.As component 22 is pressed in (in this case, end 28 moves closer to end 30), the radially facing inward surface 26 of component 22 makes contact and electrically connects with contact 80A, 180A, thereby completing the circuit between contacts 80A, 180A and 80B, 180B. Once the circuit is complete, RFID tag 70, 170 indicates that the connection is secure. Figure 4 is a perspective view of the RFID 60 assembly. The RFID 60 assembly typically comprises at least one layer (e.g., layer 62), the RFID tag 70, and at least one contact (e.g., contact 80A and / or contact 80B). In some embodiments, the RFID 60 assembly is an RFID tag connected to a first component of a connector, where the connector is arranged to connect two elements. It should be noted that the RFID 60 assembly can be used to secure any type of connection, for example, a fluid connection, a constant velocity (CV) joint, a trailer hitch connection, electrical connections, etc. The following description should be read in reference to Figures 1-4. Layer 62 comprises surfaces 64 and 66 and is operatively arranged to be secured to a component of connector 20, for example, the radially outward-facing surface 42 of component 40. In some embodiments, surface 64 comprises an adhesive and secures the RFID tag 70 and / or contact 80A to connector 20 (for example, segment 46A). It should be noted that layer 62 need not be connected to connector 20 via adhesives, but can instead be connected and / or attached using any other suitable means, for example, string, tape, hook and loop fastener, tin solder, solder, etc. In some embodiments, layer 62 is an insulator. In a disconnected state, as shown in Figures 1 and 3, contact 80A is not electrically connected to segment 46A and component 22, and contact 80B is electrically connected to segment 46A and component 22. neoznn / zznz / E / YiAi The RFID assembly 60 may further comprise an additional ferrite layer attached to the upper surface 66 (not shown), operatively arranged as a platform or base for the RFID tag 70 and / or contact 80A. In some embodiments, the RFID assembly 60 further comprises layer 68. Layer 68 is operatively arranged to cover and protect the RFID tag 70. As shown in Figure 4, layer 68 completely covers the RFID tag 70 and at least partially covers contact 80A. However, at least a portion of contact 80A is required to be exposed, for example, the exposed portion 82, so that it can be electrically coupled and connected to end 28 of component 22, as will be described in more detail below. The RFID tag 70 is disposed on surface 66 and comprises an integrated circuit (IC) or a microprogram (chip) 72 and an antenna 74. In some embodiments, the RFID tag 70 comprises a passive RFID tag. In some embodiments, the RFID tag 70 comprises an active RFID tag (and further comprises a power source). In some embodiments, the RFID tag 70 comprises a semi-passive RFID tag. In some embodiments, the RFID tag 70 is pre-programmed to transmit information, for example, a unique identification number (UID), the status of the RFID assembly 60 (in this case, open or closed), etc. The antenna 74 is connected at one end to the IC 72 at the antenna radio frequency (RF) input LA, and at the other end to the IC 72 at the antenna RF input LB, via conductors 76A and 76B, respectively. The RFID tag 70 is also connected to contact 80A and contact 80B.Specifically, conductor 78A connects contact 80A to IC 72 at the GND ground terminal and conductor 78B connects contact 80B to IC 72 at the DP detector terminal. Contact 80A is separate from contact 80B. Specifically, contact 80A is located on surface 66 of layer 62, while contact 80B is not located on layer 62. Contact 80B is located on the outward-facing radial surface 42 and is electrically connected to component 40 and component 22 of connector 20. In some embodiments, contact 80B is located on the inward-facing radial surface 26 and is electrically connected to component 40 and component 22 of connector 20. It should be noted that contact 80B can be connected to component 40 and / or component 22 by any suitable means, such as adhesives, string, tape, hook and loop fasteners, solder, etc. In some embodiments, contacts 80A and 80B are electrically conductive.It should be noted that, in the unlocked state, as shown in Figures 1 and 3, contact 80B is always electrically connected to component 22, and contact 80A is not electrically connected to component 22. When connector 20 is properly secured, end 28 of component 22 is inserted and electrically connected to contact 80A. In some embodiments, component 22 and / or component 40 comprise an electrically conductive material (e.g., metal). As such, when end 28 is connected to contact 80A, component 22 completes the circuit between contacts 80A-80B and IC 72, causing RFID tag 70 to become enabled (in this case, RFID tag 70 may be able to be energized by an electromagnetic field generated by an external device (not shown)) or to switch to a closed state (from an open state).Before completing the circuit—that is, electrically connecting contact 80A directly to contact 80B—RFID tag 70 is not enabled (in this case, RFID tag 70 cannot be energized by an electromagnetic field generated by the external device) or, in some configurations, indicates an open state. When the circuit is completed (in this case, component 22 and / or component 40 are connected directly to contact 80A and contact 80B as shown in Figure 2), an external device, such as an RFID reader, will detect that RFID tag 70 is enabled, or in a closed state, thus indicating that RFID connector 10 is correctly connected. In other words, when RFID tag 70 is enabled, the RFID reader will identify its presence and, therefore, determine that RFID connector 10 is correctly connected.When the circuit is incomplete (in this case, contact 80A is not directly connected to contact 80B), the RFID reader will not detect an enabled RFID tag 70, indicating that RFID connector 10 is not properly connected. In other words, when RFID tag 70 is disabled, the RFID reader will not recognize that RFID tag 70 exists and will therefore determine that RFID connector 10 is not properly connected. In some configurations, RFID tag 70 is always enabled and can be detected and read by an RFID reader regardless of whether contacts 80A and 80B are connected. In such configurations, when contacts 80A and 80B are not directly connected, for example, via component 22 and / or component 40, RFID tag 70 is still able to transmit certain information to an RFID reader. This information may include, but is not limited to, a UID number (e.g., for the RFID tag, connector type, etc.), size number, model number, serial number, status of RFID tag 70 (in this case, open or closed), Uniform Resource Locator (URL), station ID (in this case, manufacturer's LOT number), date / time stamp, description, etc. In other words, regardless of whether contacts 80A and 80B are connected, the REID 70 tag will always transmit certain data (e.g., a UID number, a status, etc.).provided it is functioning correctly. In this way, the REID 70 tag is pre-programmed to always transmit at least one UID number and a status (in this case, open or closed), for example, using hexadecimal data or a value. This is important because it allows the user to scan a given REID tag to determine if it is functioning correctly (in this case, if the REID tag is transmitting data correctly, then it is functioning correctly), as well as to determine its current status (in this case, open or closed). When contacts 80A and 80B are connected, for example, via component 22 and / or component 40, the RFID 70 tag transmits data indicating a closed state.In some configurations, the RFID 70 tag 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. It should be noted that the RFID 70 tag can include any programming suitable for indicating that it is functioning correctly and for differentiating between an open and a closed state, and that this description should not be limited solely to the use of the hexadecimal system. Figure 5 is a perspective view of the RFID 160 assembly. Figure 6 is a cross-sectional view of the RFID 160 assembly, typically taken along line 6-6 in Figure 5. The RFID 160 assembly generally comprises at least one layer (e.g., layer 162), an RFID tag 170, and at least one contact (e.g., contact 180A and / or contact 180B). In some embodiments, the RFID 160 assembly is an RFID tag connected to a first component of a connector, where the connector is arranged to connect two elements. It should be appreciated that the RFID 160 assembly can be used to secure any type of connection, e.g., a fluid connection, a CV joint, a trailer hitch connection, electrical connections, etc. The following description should be read in reference to Figures 1-6. Layer 162 comprises surfaces 164 and 166 and is operatively arranged to be attached to a component of connector 20, for example, the radially outward-facing surface 42 of component 40 (for example, segment 46A). In some embodiments, surface 164 comprises an adhesive and secures the RFID tag 170 and / or contact 180A and / or contact 180B to connector 20. It should be noted that layer 162 need not be attached to connector 20 by means of adhesives, but may be attached and / or applied using any other suitable means, for example, string, tape, hook and loop fastener, tin solder, solder, etc. In some embodiments, layer 162 is an insulator. In a disconnected state, as shown in Figures 1 and 3, contact 180A is not electrically connected to segment 46A and component 22, and contact 180B is electrically connected to segment 46A and component 22. The RFID assembly 160 may further comprise an additional ferrite layer attached to the upper surface 166 (not shown) operatively arranged as a platform or base for the RFID tag 170 and / or contact 180A. In some embodiments, the RFID assembly 160 further comprises layer 168. Layer 168 is operatively arranged to cover and protect the RFID tag 170 and / or contact 180A. As shown in Figures 5-6, layer 168 completely covers the RFID tag 170 and at least partially covers contact 180A. However, at least a portion of contact 180A, for example, the exposed portion 182, is required to be exposed so that it is capable of mating and electrically connecting to the end of component 22, as will be described in more detail below. The REID tag 170 is disposed on surface 166 and comprises an IC or chip 172 and an antenna 174. In some embodiments, the REID tag 170 comprises a passive REID tag. In some embodiments, the REID tag 170 comprises an active REID tag (and further comprises a power source). In some embodiments, the REID tag 170 comprises a semi-passive REID tag. In some embodiments, the REID tag 170 is pre-programmed to transmit information, for example, a UID number, the status of the REID assembly 160 (in this case, open or closed), etc. The antenna 174 is connected at one end to IC 172 at antenna input RE LA, and at the other end to IC 172 at antenna input RE LB, via conductors 176A and 176B, respectively. The REID 170 label is also connected to contact 180A and contact 180B.Specifically, conductor 178A connects contact 180A to IC 172 at the GND ground terminal and conductor 178B connects contact 180B to IC 172 at the DP detector terminal. Contact 180A is separate from contact 180B. Specifically, contact 180A is located on surface 166 of layer 162, and contact 180B is located on surface 164 of layer 162. 180B is arranged on the outwardly facing radial surface 42 and is electrically connected to component 40 and component 22 of connector 20. In some embodiments, contacts 180A and 180B are electrically conductive. It should be noted that, in the unlocked state, as shown in Figures 1 and 3, contact 180B is always electrically connected to component 22 (via segment 46A) and contact 180A is not electrically connected to component 22. When connector 20 is properly secured, the end 28 of component 22 engages in a coupling and makes an electrical connection with contact 180A. In some embodiments, component 22 and / or component 40 comprise an electrically conductive material (e.g., metal).As such, component 22 completes the circuit between contacts 180A-180B and IC 172, causing RFID tag 170 to become enabled (in this case, RFID tag 170 has the ability to receive energy from an electromagnetic field generated by an external device (not shown)) or to switch to a closed state (from an open state). Before completing the circuit, i.e., electrically connecting contact 180A directly to contact 180B, RFID tag 170 is not enabled (in this case, RFID tag 170 cannot be energized by an electromagnetic field generated by the external device) or, in some modes, indicates an open state.When the circuit is complete (in this case, component 22 and / or component 40 directly connect contact 180A and contact 180B as shown in Figure 2), an external device such as an RFID reader will detect that RFID tag 170 is enabled or in a closed state, indicating that RFID connector 10 is correctly connected. In other words, when RFID tag 170 is enabled, the RFID reader will identify its presence and thus determine that RFID connector 10 is correctly connected. When the circuit is incomplete (in this case, contact 180A is not directly connected to contact 180B), the RFID reader will not detect an enabled RFID tag 170, indicating that RFID connector 10 is not correctly connected.Put another way, when RFID tag 170 is disabled, the RFID reader will not identify that RFID tag 170 exists and will thus determine that RFID connector 10 is not properly connected. In some configurations, RFID tag 170 is always enabled and can be detected and read by an RFID reader regardless of whether contacts 180A and 180B are connected. In such configurations, when contacts 180A and 180B are not directly connected, for example, via component 22 and / or component 40, RFID tag 170 can transmit certain information to an RFID reader. This information may include, but is not limited to, a UID number (e.g., for the RFID tag, connector, etc.), size number, model number, serial number, RFID tag 170 status (in this case, open or closed), URL, station ID (in this case, the manufacturing BATCH number), date / time stamp, description, etc. In other words, regardless of whether contacts 180A and 180B are connected, the RFID tag 170 will always transmit certain data (e.g., a UID number, a status, etc.).provided it is functioning correctly. In this way, the RFID tag 170 is pre-programmed to always transmit at least one UID number and a status (in this case, open or closed), for example, using hexadecimal data or a value. This is important because it allows the user to scan a given RFID tag to determine if it is functioning correctly (in this case, if the RFID tag is transmitting data correctly, then it is functioning correctly), as well as to determine its current status (in this case, open or closed). When contacts 180A and 180B are connected, for example, by component 22 and / or component 40, the RFID tag 170 transmits data indicating a closed state.In some configurations, the RFID 170 tag indicates a first value (e.g., a first hexadecimal value) neoznn / zznz / E / YiAi for an open state and a second value (e.g., a second hexadecimal value) for a closed state; the second value is different from the first. It should be noted that the RFID 170 tag can include any suitable programming to indicate that it is functioning correctly and to differentiate between an open and a closed state, and that this description should not be limited to the use of the hexadecimal system alone. Figure 7 is a perspective view of the RFID assembly 260. Figure 8 is a close-up view of the RFID connector 10, typically taken along detail 8 in Figure 1. The RFID assembly 260 generally comprises at least one layer (e.g., layer 262), the RFID tag 270, and at least one contact (e.g., contact 280). In some embodiments, the RFID assembly 260 is an RFID tag attached to a connector or clamp, where the connector or clamp is arranged to connect two elements together. It should be appreciated that the RFID assembly 260 can be used to secure any type of connection, e.g., a fluid connection, a constant velocity joint, a trailer hitch connection, electrical connections, etc. The following description should be read in view of Figures 1-3 and 7-9B. Layer 262 comprises surfaces 264 and 266 and is operatively arranged to be secured to a component of connector 20, for example, the radially outward-facing surface 42 of component 40 (for example, segment 46A). In some embodiments, surface 264 comprises an adhesive and secures the RFID tag 270 and / or contact 280 to connector 20. It should be noted that layer 262 need not be connected to connector 20 via adhesives, but rather may be connected and / or applied using any other suitable means, for example, string, tape, hook and loop fastener, tin solder, solder, etc. In some embodiments, layer 262 is an insulator. The RFID assembly 260 may further comprise an additional ferrite layer attached to the upper surface 266 (not shown) operatively arranged as a platform or base for the RFID tag 270 and / or the contact 280. In some embodiments, the RFID assembly 260 further comprises layer 268. Layer 268 is operatively arranged to cover and protect the RFID tag 270 and / or the contact 280. As shown in Figure 7, layer 268 completely covers the RFID tag 270 and at least partially covers the contact 280. However, at least a portion of the contact 280 is required to be exposed, for example, the exposed portion 282, so that it has the ability to couple and electrically connect to the end 28 of component 22, as will be described in more detail below. The RFID tag 270 is disposed on surface 266 and comprises an IC or chip 272 and an antenna 274. In some embodiments, the RFID tag 270 comprises a passive RFID tag. In some embodiments, the RFID tag 270 comprises an active RFID tag (and further comprises a power source). In some embodiments, the RFID tag 270 comprises a semi-passive RFID tag. In some embodiments, the RFID tag 270 is pre-programmed to transmit information, for example, a UID number, the status of the RFID assembly 260 (in this case, open or closed), etc. The antenna 274 is connected at one end to the IC 272 at the RF antenna input LA, and at the other end to the IC 272 at the RF antenna input LB, via conductors 276A and 276B, respectively. The RFID tag 270 is additionally connected to contact 280.Specifically, conductor 278A connects contact 280 to IC 272 at the GND ground terminal and conductor 278B connects contact 280 to IC 272 at the DP detector terminal. Contact 280 is disposed on surface 266 of layer 262. Contact 280 is disposed on the radially outward-facing surface 42. Contact 280 is operatively arranged to engage with component 22, for example, end 28. In some embodiments, contact 280 is a pressure-sensitive contact. When the RFID connector 10 is properly connected, end 28 engages with contact 280 and applies pressure to it. In some embodiments, connector 20 comprises a metal. In some embodiments, connector 20 comprises a non-metallic material, such as a polymer or an elastomer. It should be appreciated that connector 20 can comprise any material suitable for applying pressure to contact 280.Once sufficient pressure is applied to contact 280, the circuit is completed between conductors 278A and 278B and IC 272, enabling RFID tag 270 (in this case, RFID tag 270 can be energized by an electromagnetic field generated by an external device (not shown)) or indicating 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 (in this case, RFID tag 270 cannot be energized by an electromagnetic field generated by the external device) or indicates an open state.When the circuit is complete (in this case, connector 20 applies sufficient pressure to contact 280, thereby electrically connecting conductor 278A directly to conductor 278B), an external device such as an RFID reader will detect that RFID tag 270 is enabled or in a closed state, indicating that RFID connector 10 is properly connected. In other words, when RFID tag 270 is enabled, the RFID reader will identify its presence and thus determine that RFID connector 10 is properly connected. When the circuit is incomplete (in this case, the ends of conductors 278A are not directly connected to contact 278B), the RFID reader will not detect an enabled RFID tag 270, indicating that RFID connector 10 is not properly connected.Put another way, when RFID tag 270 is disabled, the RFID reader will not identify that RFID tag 270 exists and will therefore determine that RFID connector 10 is not properly connected. In some configurations, the RFID tag 270 is always enabled and can be detected and read by an RFID reader regardless of whether the conductive layers 290 and 294 (in this case, conductors 278A and 278B) are in direct contact. In such configurations, and as described above, when the conductive layers 290 and 294 (in this case, conductors 278A and 278B) are not directly connected, for example, by force from component 22, the RFID tag 270 can transmit certain information to an RFID reader. This information may include, but is not limited to, a UID number, size number, model number, serial number, the status of the RFID tag 270 (in this case, open or closed), URL, station ID, date / time stamp, description, etc.In other words, regardless of whether conductive layers 290 and 294 (in this case, conductors 278A and 278B) are connected, REID tag 270 will always transmit data (e.g., a UID number, a status, etc.) as long as it is functioning correctly. Therefore, REID tag 270 is pre-programmed to always transmit at least a UID number and a status (in this case, open or closed), for example, using hexadecimal data or a value. This is important because it allows the user to scan a given REID tag to determine if it is functioning correctly (in this case, if the REID tag is transmitting data correctly, then it is functioning correctly), as well as to determine its current status (in this case, open or closed).When conductive layers 290 and 294 (in this case, conductors 278A and 278B) are connected, for example, by applying a suitable force F to layer 294 through component 22 (for example, end 28), the RFID tag 270 transmits data indicating a closed state. In some embodiments, the RFID tag 270 indicates a first value (for example, a first hexadecimal value) for an open state and a second value (for example, a second hexadecimal value) for a closed state; the second value is different from the first. It should be appreciated that the RFID tag 270 can include any suitable programming to indicate that it is functioning correctly and to differentiate between an open and a closed state, and that the present description should not be limited to the use of the hexadecimal system alone. Figure 9A is a schematic partial cross-sectional view of the RFID assembly 260 in an open (or disabled) state, according to some embodiments of the present description. It should be appreciated that this is only one embodiment of a pressure-sensitive contact, and that various other pressure-sensitive contacts known in the prior art or that may be developed in the future can be used. The contact 280 comprises a conductive layer 290, an insulating layer 292, and a conductive layer 294. The conductive layer 290 is disposed on the surface 266 of layer 262. In some embodiments, the conductive layer 290 is disposed on an additional ferrite layer disposed on surface 266 (not shown). In some embodiments, the conductive layer 290 is disposed on the radially outward-facing surface 42 of segment 46A (in this case, layer 262 is not included).The insulating layer 292 is positioned on top of layer 290. The conductive layer 294 is positioned on the upper portion of the insulating layer 292. The insulating layer 292 is operatively arranged to separate the conductive layers 290 and 294 until a sufficient force F is applied to the conductive layer 294, as will be described in more detail below. Conductor 278A connects the ground terminal GND to the conductive layer 294, and conductor 278B connects the sensing terminal DP to the conductive layer 290. In some embodiments, conductor 278A connects the ground terminal GND to the conductive layer 290, and conductor 278B connects the sensing terminal DP to the conductive layer 294.As shown in Figure 9A, conductors 278A and 278B remain disconnected, and thus RFID tag 270 will indicate an open state or remain disabled (in this case, an RFID reader would not detect the presence of RFID tag 270). Therefore, in either case, the RFID reader will indicate that RFID connector 10 is not properly secured. Figure 9B is a schematic partial cross-sectional view of the RFID assembly 260 shown in Figure 9A, in a closed (or enabled) state. When a sufficient force F is applied to the conductive layer 294, for example, through component 22, the conductive layer 294 moves through the insulating layer 292 and makes contact with the conductive layer 290. When the conductive layer 294 makes contact with the conductive layer 290, the conductors 278A and 278B are electrically connected, completing the circuit, and RFID tag 270 indicates a closed or enabled state (in this case, RFID tag 270 can be energized by an electromagnetic field generated by the RFID reader). As such, in either case, the RFID reader will indicate that RFID connector 10 is properly secured. As can be seen in the Figures, as end 28 moves toward end 30, end 28 is pushed down onto RFID assembly 260 and applies force F to contact 280, specifically to layer 294. It should be noted that the RFID tags and assemblies described here, for example, RFID tags 70, 170, and 270 and RFID assemblies 60, 160, and 260, can use any suitable radio frequency range. In some configurations, RFID tags 70, 170, and 270 comprise low-frequency (LF) RFID tags that operate in the 30 kHz to 300 kHz range and have a read range of up to 10 cm. While LF RFID tags have a shorter read range and slower data read speed than other technologies, they perform better in the presence of metals or liquids (which can interfere with other types of RFID tag transmissions). Common standards for LF RFID include ISO 14223 and ISO / IEC 18000-2. In some forms, the RFID 70, 170, and 270 tags comprise high-frequency (HF) RFID tags that operate in the 3 MHz to 30 MHz range and provide read distances of 10 cm to 1 m.In such configurations, REID 70, 170, and 270 tags can even be Near Field Communication (NFC) tags, since NFC technology is based on HF RFID. Common standards for HF RFID include ISO 15693, ECMA-340, ISO / IEC 18092 (for NFC), ISO / IEC 14443A, and ISO / IEC 14443 (for MIFARE and other smart card solutions). In some configurations, RFID 70, 170, and 270 tags incorporate ultra-high frequency (UHF) RFID, which operates in the 300 MHz to 2 GHz range and provides read distances of up to 12 m. A well-known standard for UHF RFID is EPCglobal Gen2 / ISO 18000-6C. Furthermore, in some configurations, a single RFID reader can detect and receive data from multiple RFID tags, not just one. It should be noted that various aspects of the foregoing description, and other features and functions, or alternatives thereof, may be combined as desired in many other different systems or applications. Persons skilled in the art may subsequently make various alternatives, modifications, variations, or improvements not currently foreseen or anticipated, which are also intended to be covered by the following claims.
