Description

Technical Field

[0001] This invention relates to the field of fabric inspection technology, specifically to an inspection device for easy-to-clean, UV-resistant sports fabrics. Background Technology

[0002] UV-resistant sports fabrics are functional fabrics specifically developed for sports scenarios and are widely used in the production of sportswear, fitness equipment and other products. However, during exercise, people sweat a lot, and clothing is not only easily soaked with sweat, but also easily gets stained with dust and other dirt, affecting the wearing experience and the lifespan of the clothing. In order to better meet practical applications and diverse needs, special functional additives and fibers are added when making UV-resistant sports fabrics.

[0003] For example, hydrophobic polymer additives are introduced onto the surface of the fabric fibers, which reduces the surface energy of the fabric. When stains come into contact with this fabric, due to the difference in surface energy, the stains are difficult to penetrate into the fibers and instead roll off like water droplets or are easier to remove during washing. At the same time, other materials that help achieve permanent whiteness and easy stain removal are added. These materials work together to give UV-resistant sports fabrics not only excellent UV protection but also excellent permanent whiteness and easy stain removal. In this way, even if the clothes are frequently exposed to sweat and external stains during exercise, they can remain relatively clean and tidy, greatly improving the durability and ease of care of the clothes and meeting the requirements of sports scenarios for fabric performance.

[0004] Given that the fabric must meet both the functional requirements of sports activities and special protection standards, its inspection process, in addition to the conventional fabric testing items such as flatness, thickness, and density, also requires additional special testing for UV resistance to ensure that all indicators meet the design requirements and the functional needs of the actual application scenario.

[0005] The current mainstream method requires cutting the entire roll of fabric into individual samples and then placing them one by one on a fixed testing plane of a UV tester for testing. This segmented testing mode first severs the correlation between fabric performance parameters—UV resistance performance and conventional indicators such as smoothness, thickness, and density should be comprehensively evaluated in the same testing process, but the existing process artificially separates them, making it difficult to form a systematic analysis of various data and failing to intuitively reflect the synergy of the overall fabric performance. For example, uneven fabric thickness may affect the UV shielding effect, but because the testing links are separated, it is difficult for operators to quickly establish the causal relationship between parameters, increasing the difficulty of tracing the source of quality problems.

[0006] Secondly, small sample testing cannot truly represent the average parameters of the entire roll of fabric. During the production process, fabrics may have longitudinal or transverse performance differences due to factors such as raw material distribution and process fluctuations. Small samples can only reflect the characteristics of local areas. Taking sportswear fabric as an example, if the edge area of ​​the entire roll of fabric becomes thinner and its UV resistance decreases due to stretching, but the small sample does not cover this area, the test results will not reveal this hidden danger, which may ultimately lead to batch quality problems in the final product. In addition, cutting small samples requires additional manpower and time costs. Especially for high-value-added functional fabrics, frequent cutting will cause raw material waste and increase production costs.

[0007] Finally, traditional ultraviolet detectors typically employ a separate structure consisting of a fixed detection platform and a movable light source module. While the recessed design at the top of the fixed end facilitates the fixation of small samples, it may lead to localized deformation of the fabric surface. When the fabric is laid on the recessed plane, there is a difference between its actual light-receiving area and the theoretical detection area. Furthermore, the stress changes in the fabric fibers caused by compression may alter the ultraviolet transmission path, ultimately causing the detection data to deviate from the true value. For example, the different degrees of stretching of elastic fabrics on the recessed plane may cause the ultraviolet transmittance test results for the same area to fluctuate by 10%-15%, seriously affecting the reliability of the test results.

[0008] Furthermore, the inefficiency of the existing testing process is also reflected in the data integration and analysis stage. Since UV resistance performance and conventional parameters are tested by different equipment and personnel, the data must be manually summarized before comprehensive evaluation can be carried out. This not only prolongs the testing cycle, but may also lead to data distortion due to human error in recording. In the fast-paced production scenario of sports fabrics, this lagging testing mode is difficult to meet the needs of real-time quality control and cannot provide timely data support for production process adjustments. This may lead to defective products flowing into subsequent stages, increasing quality risks and rework costs.

[0009] Therefore, this invention proposes an inspection device for easily stain-resistant and UV-resistant sports fabrics. Summary of the Invention

[0010] The purpose of this invention is to provide an easy-to-clean, UV-resistant sports fabric inspection device to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution: an easy-to-clean, UV-resistant sports fabric inspection device, comprising a body, wherein a micro-tension rod assembly is inclinedly installed inside the body, reciprocating motion components are symmetrically installed inside the body, and UV detection modules are installed on the outside of each reciprocating motion component, and limit components are installed on the outside of each UV detection module;

[0012] During the fabric conveying process, the fabric reduces the tension it experiences through the micro-tension bar group, and the reciprocating motion component drives the ultraviolet detection module to move and perform ultraviolet resistance detection on the moving fabric. The limiting component limits the movement of the ultraviolet detection module, ensuring that it is close to the fabric during detection to guarantee detection accuracy, and that it is not close to the fabric when not detecting.

[0013] Preferably, the micro-tension bar assembly includes:

[0014] Several mounting bases are arranged linearly and equidistantly and fixedly connected to the inner wall of the machine body;

[0015] Several smooth rollers are rotatably connected to the interior of the mounting base, wherein the axial length of the smooth rollers at both ends is greater than that of the smooth roller in the middle.

[0016] Synchronous belt one, which is connected to the surface of the smooth roller.

[0017] Preferably, a take-up roller and an unwind roller are respectively installed on both sides of the machine body, and a rotating hole is opened on the surface of the machine body. The smooth roller is connected to an external drive device through the rotating hole, and the rotation speed of the external drive device is the same as the rotation speed of the take-up roller and the unwind roller. The external drive device is specifically a motor.

[0018] Preferably, the axial direction of the smooth roller is inclined at an acute angle to the conveying direction of the fabric, and the inclination direction is such that the component force along the axial direction of the smooth roller generated by the fabric under the action of gravity is opposite to the tension generated by the fabric during the conveying process.

[0019] Preferably, the reciprocating motion component includes:

[0020] A double-layer hollow shell is disposed above the micro-tension rod assembly. Several fixing rods are fixedly connected between the top of the double-layer hollow shell and the top of the inner cavity of the machine body. The inner surface of the double-layer hollow shell is smooth, and both ends of its inner edge are rounded. The rounded corners are concentric with the smooth roller.

[0021] Synchronous belt two, which is driven and connected to the surfaces of smooth rollers located at both ends;

[0022] A rod-shaped base, which is fixedly connected to the surface of the second synchronous belt;

[0023] A synchronization plate is fixedly connected to the surface of the sample stage, and a synchronization groove is provided in the middle of the plate. The synchronization groove is slidably connected to the rod-shaped base.

[0024] Preferably, the ultraviolet detection module consists of a sample stage and an ultraviolet light module. The sample stage is slidably connected inside the double-layer hollow shell, and the ultraviolet light module is slidably connected to the surface of the sample stage. The top of the sample stage is flush with the top edge of the bottom layer of the double-layer hollow shell. The light emitted by the ultraviolet light module is always perpendicular to the fabric on the sample stage. The circuit of the ultraviolet detection module is led out from the power supply, wired through the double-layer hollow shell to the sample stage and the ultraviolet light module, and is externally mounted with a tank chain, one end of which is fixed to the body, and the circuit is orderly extended and retracted as the ultraviolet detection module moves.

[0025] The ultraviolet detection module also includes:

[0026] A spring is fixedly connected between the sample stage and the ultraviolet light module.

[0027] Preferably, the limiting member includes:

[0028] A limiting rod is fixedly connected to the surface of the ultraviolet light module;

[0029] A limiting track is fixedly connected to the inside of a double-layer hollow shell, and a limiting rod is slidably connected to the inside of the limiting track.

[0030] The arc block is rotatably connected to the inner edge of the limiting track.

[0031] A limiting block is fixedly connected to the inner edge of the limiting track.

[0032] Preferably, when the limiting rod slides inside the limiting track, the limiting rod contacts the passing arc block and causes it to rotate; when the limiting rod continues to slide until it no longer contacts the passing arc block, the passing arc block resets based on its own gravity; after resetting, the passing arc block, under the restriction of the limiting block, prevents the limiting rod from returning along the original path during subsequent movement.

[0033] Preferably, an appearance inspection module is installed on the outside of the machine body, at the part of the fabric that has not passed through the micro-tension bar group. The appearance inspection module is used to detect the key parameters of the fabric, including but not limited to the fabric's flatness, surface pressure distribution, thickness uniformity, etc. Both the appearance inspection module and the ultraviolet detection module are electrically connected to an external digital display module. The detected parameters are transmitted to the external digital display module in real time and displayed in an intuitive data form, so that the operator can keep track of the various performance indicators of the fabric at any time.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. The reciprocating motion component is linked with the smooth roller via a synchronous belt, so that the ultraviolet detection module and the fabric move at the same speed, forming a "dynamic relative static" detection environment. The sliding pair design of the rod-shaped base and the sample stage ensures the accuracy of the module's motion trajectory and avoids shaking deviation. The smooth inner surface and rounded corner guide structure of the double-layer hollow shell reduce motion resistance and airflow disturbance, so that the detection module can operate smoothly. The above design breaks through the limitations of traditional static detection and can continuously scan the moving fabric to capture the fluctuation of the UV resistance performance of the entire roll of fabric in real time.

[0036] 2. The micro-tension rod assembly utilizes the mechanical design of the inclined smooth roller to offset the conveying tension by using the component of the fabric's gravity, avoiding the stretching deformation caused by traditional high tension. The structure of the smooth roller with its ends longer than the middle can disperse the tension at the edge of the fabric and prevent width shrinkage. The synchronous belt drive ensures that all rollers rotate at the same speed, avoiding wrinkles caused by roller speed differences. This low-tension conveying mode allows the fabric to enter the inspection stage in a flat state, laying the foundation for subsequent high-precision inspection. It is especially suitable for the stable conveying of elastic or sensitive functional fabrics.

[0037] 3. The limiting mechanism, through a limiting rod and a one-way limiting block, ensures that the detection module remains in close contact with the fabric during forward movement and automatically disengages during return. During detection, the limiting rod pushes the arc block to rotate, causing the ultraviolet light module to descend to the standard detection distance, with spring elastic support adapting to slight fabric undulations. During return, the arc block returns to its original position due to gravity and is blocked by the limiting block, forcing the limiting rod to slide upward along another path, lifting the module and preventing friction and wear with the fabric. This mechanism ensures detection accuracy and extends the equipment's lifespan, making it particularly suitable for high-frequency continuous detection scenarios.

[0038] 4. The equipment integrates micro-tension conveying, dynamic ultraviolet detection, and multi-parameter synchronous acquisition into the same body. The appearance inspection module can detect conventional indicators such as flatness and thickness in real time, and transmit them synchronously with the ultraviolet resistance data to the digital display module. This one-stop inspection mode avoids the manual intervention and data fragmentation of traditional segmented inspection, greatly improving inspection efficiency. Continuous sampling of the whole roll reduces sample deviation, making it especially suitable for batch inspection of high-cost fabrics. It can provide real-time feedback on quality issues and prevent unqualified products from flowing into subsequent processes.

[0039] 5. The vertical irradiation design of the ultraviolet light module strictly matches the ultraviolet radiation conditions of the national standard. The micro-tension rod group and the limiting component work together to control the flatness of the fabric, meeting the requirement of flat and wrinkle-free sample. The dynamic relative static detection mode makes the fabric position relative to the light source stable, which is equivalent to the static detection accuracy. The detection results have a high degree of agreement with the standard method. The average parameters of continuous detection of the whole roll are closer to the actual performance of the fabric, and ensure the representativeness and reliability of the detection data.

[0040] 6. The external digital display module integrates multi-dimensional detection data in real time and dynamically displays the correlation between UV resistance performance and physical parameters, making it easy for operators to quickly locate quality problems. For example, when the thickness uniformity fluctuates, the system can automatically trigger the UV detection module to encrypt sampling, establish a parameter correlation model, and provide data support for process adjustment. This intelligent integration mode breaks the information silos of traditional detection and realizes closed-loop control of the entire process from detection to feedback, significantly improving the efficiency and scientific nature of quality control in the production of functional fabrics.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0057] It should be noted that the take-up roller and unwind roller only provide the function of conveying the fabric, the ultraviolet detection module 23 adopts the ultraviolet transmittance tester in the prior art, and the appearance detection module only provides parameter detection of the appearance of the fabric. The working principle and specific structure of the above structure are all existing technologies. Therefore, given the universality of the above structure, its specific principle will not be described in detail below.

[0058] It should be noted that the national standard GB / T18830-2009 specifies the test method for the UV resistance of textiles. The core requirements include the UV radiation source, the method of fixing the fabric sample, and the detection wavelength range. The UV light module 232 of this equipment can simulate the UV radiation conditions specified in the standard through vertical irradiation design. In addition, the synergistic effect of the limiting component 24 and the micro-tension rod group 21 can control the tension and positional stability of the fabric during testing, thereby avoiding the fabric deformation caused by the traditional concave platform and meeting the test requirement that "the sample should be flat and wrinkle-free".

[0059] Secondly, this equipment, through continuous whole-roll testing and multi-position dynamic sampling, can better reflect the average parameters of the fabric compared to traditional small-sample testing, thus reducing sample bias.

[0060] Please refer to the example below. Figures 1 to 10 As shown, the present invention provides an embodiment: an easy-to-clean, UV-resistant sports fabric inspection device, including a body 11, a micro-tension rod group 21 installed at an incline inside the body 11, reciprocating motion components 22 symmetrically installed inside the body 11, UV detection modules 23 installed on the outside of each reciprocating motion component 22, and limit components 24 installed on the outside of each UV detection module 23.

[0061] During the fabric conveying process, the fabric reduces the tension it experiences through the micro-tension bar group 21, and the reciprocating motion component 22 drives the ultraviolet detection module 23 to move and perform ultraviolet resistance detection on the moving fabric. The limiting component 24 limits the movement of the ultraviolet detection module 23, ensuring that it is close to the fabric during detection to guarantee detection accuracy, and that it is not close to the fabric when not detecting.

[0062] It should be noted that the micro-tension bar assembly 21 includes: several mounting seats 211, all of which are linearly and equidistantly arranged and fixedly connected to the inner wall of the machine body 11; several smooth rollers 212, all of which are rotatably connected to the inside of the mounting seats 211, wherein the axial length of the smooth rollers 212 located at both ends is greater than that of the smooth rollers 212 in the middle; a timing belt 213, which is drivenly connected to the surface of the smooth rollers 212; a take-up roller and an unwind roller are respectively installed on both sides of the machine body 11; a rotating hole is opened on the surface of the machine body 11, and the smooth rollers 212 are connected to an external drive device through the rotating hole, and the rotation speed of the external drive device is the same as the rotation speed of the take-up roller and the unwind roller. The external drive device is specifically a motor. The axial direction is inclined at an acute angle to the fabric conveying direction. This inclination ensures that the component force generated by the fabric under gravity along the axial direction of the smooth roller 212 is opposite to the tension generated during fabric conveying. The reciprocating motion component 22 includes: a double-layer hollow shell 221, positioned above the micro-tension rod assembly 21; several fixed rods fixedly connected between the top of the double-layer hollow shell 221 and the top of the inner cavity of the machine body 11; the inner surface of the double-layer hollow shell 221 is smooth, and both ends of its inner edge are rounded, concentrically with the smooth roller 212; a second synchronous belt 222, which is driven and connected to the surfaces of the smooth rollers 212 at both ends; and a rod-shaped base 223, which is fixedly connected to... The surface of the synchronization belt 222, the synchronization plate 224, the synchronization plate 224 is fixedly connected to the surface of the sample stage 231, and a synchronization groove is opened in the middle of the synchronization groove. The synchronization groove is slidably connected to the rod-shaped base 223. The ultraviolet detection module 23 consists of the sample stage 231 and the ultraviolet light module 232. The sample stage 231 is slidably connected to the inside of the double-layer hollow shell 221, and the ultraviolet light module 232 is slidably connected to the surface of the sample stage 231. The top of the sample stage 231 is flush with the top edge of the bottom layer of the double-layer hollow shell 221. The light emitted by the ultraviolet light module 232 is always perpendicular to the fabric on the sample stage 231. After the circuit of the ultraviolet detection module 23 is led out from the power supply, it is wired through the double-layer hollow shell 221 to the sample stage 231 and the ultraviolet light module 232. Module 232, with a tank chain externally mounted, one end fixed to the body 11, moves and retracts the circuit in an orderly manner with the ultraviolet detection module 23. The ultraviolet detection module 23 also includes: a spring 233, which is fixedly connected between the sample stage 231 and the ultraviolet irradiation module 232. The limiting component 24 includes: a limiting rod 241, which is fixedly connected to the surface of the ultraviolet irradiation module 232; a limiting track 242, which is fixedly connected to the inside of the double-layer hollow shell 221, with the limiting rod 241 slidably connected to the inside of the limiting track 242; an arc block 243, which is rotatably connected to the inner edge of the limiting track 242; and a limiting block 244, which is fixedly connected to the inner edge of the limiting track 242.

[0063] It should be noted that when the limiting rod 241 slides inside the limiting track 242, the limiting rod 241 contacts the passing arc block 243 and causes it to rotate; when the limiting rod 241 continues to slide until it no longer contacts the passing arc block 243, the passing arc block 243 resets based on its own gravity; after resetting, the passing arc block 243, under the restriction of the limiting block 244, prevents the limiting rod 241 from returning along the original path in subsequent movements.

[0064] It should be noted that an appearance inspection module is installed on the outside of the machine body 11, in the part of the fabric that has not passed through the micro-tension bar group 21. The appearance inspection module is used to detect the key parameters of the fabric, including but not limited to the fabric's flatness, surface pressure distribution, thickness uniformity, etc. Both the appearance inspection module and the ultraviolet detection module 23 are electrically connected to the external digital display module. The detected parameters are transmitted to the external digital display module in real time and displayed in an intuitive data form, so that the operator can keep track of the various performance indicators of the fabric at any time.

[0065] Specifically, the Yongbai easy-to-clean, UV-resistant sports fabric to be tested is drawn out from the unwinding roller and passed around the smooth roller 212 of the micro-tension bar group 21 in sequence. While ensuring that the fabric is flatly attached to the surface of the smooth roller 212, it is also necessary to ensure that both sides of the fabric are flatly attached to the inner surface of the double-layer hollow shell 221. Finally, the end of the fabric is fixed to the take-up roller.

[0066] It should be noted that during the threading process, the wrap angle of the fabric on the micro-tension bar group 21 must be kept uniform to avoid folding or skewing. Since the axis of the smooth roller 212 is inclined at an acute angle to the fabric conveying direction, the fabric naturally forms a segmented and inclined conveying path after threading.

[0067] Then, the external drive device is activated, which drives the smooth rollers 212 at both ends to rotate through the rotating hole. The synchronous belt 213 drives the middle smooth roller 212 in linkage to ensure that all smooth rollers 212 rotate at the same speed. At the same time, the take-up roller and the unwind roller are controlled by the same drive system, and their speed is synchronized with the smooth rollers 212 to form a closed-loop constant speed conveying system. During this process, the appearance inspection module will detect parameters such as the flatness and thickness of the fabric.

[0068] The inclined setting of the smooth roller 212 causes the fabric to generate a component force along the roller axis under the action of gravity. This component force is opposite to the tension direction of the fabric conveying direction, forming a dynamic balance. Specifically, the gravity component force is mainly used to counteract the tension, reduce the effective tension actually borne by the fabric, and maintain the stability of the low tension environment.

[0069] When the smooth roller 212 rotates, it drives the rod-shaped base 223 to move along the synchronous belt 222. At the same time, since the rod-shaped base 223 is slidably connected to the synchronous plate 224, the rod-shaped base 223 also drives the synchronous plate 224 and the ultraviolet detection module 23 to move synchronously.

[0070] When the ultraviolet detection module 23 moves toward the fabric, it will synchronously drive the limiting rod 241 to move. However, since the limiting rod 241 is restricted by the limiting track 242, in order to move synchronously with the ultraviolet detection module 23, the limiting rod 241 will slide down along the limiting track 242 due to its contact with the inner wall of the limiting track 242. At this time, the ultraviolet light module 232 descends, and the spring 233 is in a stretched state. At this time, the ultraviolet light module 232 emits ultraviolet light perpendicular to the fabric surface. The ultraviolet detection module 23 collects the intensity of ultraviolet light transmitted through the fabric in real time through the built-in ultraviolet sensor and calculates the ultraviolet protection coefficient by combining the incident light intensity.

[0071] It should be noted that in existing technologies, static sample testing is limited by the duration of a single light exposure because the fabric is fixed. However, this device achieves dynamic relative static testing by keeping the ultraviolet detection module 23 moving at the same speed as the fabric, thus solving the core problem of "insufficient effective testing time" in dynamic testing. The test results are consistent with those of static standard testing.

[0072] As the limiting rod 241 moves continuously, when the limiting rod 241 reaches the passing arc block 243, the limiting rod 241 abuts against the passing arc block 243 and causes it to rotate, allowing the limiting rod 241 to pass through. Subsequently, the passing arc block 243 resets due to gravity.

[0073] At this time, the limiting rod 241 moves to the end of the limiting track 242, but the rod-shaped base 223 begins to move downward following the timing belt 222. Since the sample stage 231 is restricted from moving by the double-layer hollow shell 221, the rod-shaped base 223 slides to the bottom of the inner cavity of the timing plate 224 and drives the sample stage 231 to move in the opposite direction.

[0074] The limiting block 244 restricts the reverse rotation of the arc block 243, so the limiting rod 241 can only slide up along the limiting track 242. At the same time, the sample stage 231 returns under the drive of the rod-shaped base 223, and the spring 233 is stretched, which increases the distance between the ultraviolet light module 232 and the fabric surface, avoiding contact wear between the module and the fabric during the return stroke.

[0075] It should be noted that in the existing technology, UV protection detection requires multiple small-sample cutting for discrete detection, and the detection steps of different parameters are independent of each other, resulting in low efficiency and poor data correlation. However, this device uses the one-way limiting mechanism of limit block 244 and arc block 243 to enable the UV detection module 23 to achieve multi-position dynamic detection during reciprocating motion.

[0076] This dynamic detection mode integrates the traditional discrete "sampling-detection-re-sampling" process into continuous online detection, greatly improving detection efficiency and avoiding losses from small sample cutting. It is especially suitable for batch detection of high-cost functional fabrics. At the same time, this device combines the flatness, thickness and other data collected synchronously by the appearance inspection module to achieve multi-dimensional fusion detection of UV resistance and physical parameters.

[0077] It should be noted that the design of this equipment strictly follows the core requirements of the national standard GB / T18830-2009: the vertical irradiation design of the ultraviolet light module 232 can accurately simulate standard ultraviolet radiation conditions, and its wavelength range, irradiance stability and fabric detection distance are fully matched with the national standard.

[0078] Through the synergistic effect of the micro-tension bar group 21 and the limiting member 24, the fabric always maintains a flat and wrinkle-free ideal state during testing, which fully meets the stringent requirements of the national standard for "sample fixing method".

[0079] In particular, the equipment uses a synchronous transmission system to keep the ultraviolet detection module 23 moving at the same speed as the fabric, forming a "dynamic relative static" detection environment. This innovative design ensures that the position of the fabric relative to the light source remains stable during the detection process, which is equivalent to the sample fixation effect in traditional static detection. This avoids the illumination deviation caused by relative movement in dynamic detection and meets the national standard requirements for detection time and data accuracy, achieving seamless integration between dynamic detection and static standards.

[0080] It should be noted that although the individual technologies for UV resistance testing and fabric physical parameter testing are relatively mature, integrating multi-dimensional testing into the same process still faces many challenges in actual production, such as spatial layout conflicts of testing equipment, data interference during movement, and the accuracy of multi-module collaborative control. This invention innovatively integrates micro-tension conveying, dynamic UV detection, and synchronous multi-parameter acquisition into the same machine body 11. Through precise mechanical structure design and collaborative optimization of the control system, synchronous detection of UV resistance performance, flatness, thickness, and other parameters is achieved during continuous fabric transport.

[0081] This "full-process integrated" testing mode not only overcomes the efficiency bottleneck of traditional segmented testing, but also provides a systematic solution for fabric quality control through real-time data fusion, promoting the functional fabric testing technology towards intelligence and efficiency.

[0082] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
