Description

Technical Field

[0001] The present invention relates to the technical field of purity detection of extracted components, and in particular to a purity measurement device and method for extracting soothing components. Background Art

[0002] Extraction of soothing ingredients refers to extracting chemical ingredients that can soothe sensitive skin and reduce inflammatory reactions from plants or other natural sources. In the prior art, different extraction methods are disclosed, such as the extraction method of a pure natural soothing and anti-aging ingredient from Centella asiatica disclosed in Chinese patent document CN114886815A, and the anti-allergic soothing composition containing Menyanthes leaf extract and its preparation method disclosed in CN112656726A. In fact, there are many effective soothing ingredients available. Even for the same soothing ingredient, the specific proportion of impurity components varies based on its different extraction and preparation methods. Testing the yield, purity, and actual efficacy of allergy-relieving ingredient extracts is essential. High-performance liquid chromatography (HPLC) is a common method for purity testing. HPLC separates components of a test mixture based on their interactions in two immiscible phases (stationary phase and mobile phase), followed by chromatographic testing. Therefore, for different allergy-relieving ingredients, or even for the same allergy-relieving ingredient prepared using different extraction methods, appropriate chromatographic columns (stationary phase), solvents (mobile phase), and testing parameters must be employed for purity testing to obtain a purity value that is closer to the true value.

[0003] In actual operation, multiple liquid chromatographs are often used to detect different components, or when the number of liquid chromatographs is insufficient, manual settings are made to detect different components. Even if a single liquid chromatograph is equipped with multiple detectors or detection positions to cope with complex analysis tasks, considering that component extracts are often sent to the testing laboratory in batches, it is still necessary to manually place the corresponding components in the corresponding detectors or detection positions in sequence and in a quantitative manner. The operation is cumbersome and consumes a lot of working hours and waiting time. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a purity measurement device and method for extracting soothing ingredients, so as to solve the problems of complicated operation, large amount of working hours and intermediate waiting time when batch purity detection of soothing extract ingredients is carried out.

[0005] Based on the above objectives, the present invention provides a purity measurement device for extracting soothing ingredients, including a detection platform, a liquid chromatograph provided on the detection platform, and further comprising:

[0006] The sample rack is located next to the liquid chromatograph, and is provided with a transfer chamber on the sample rack, a conveyor belt is provided in the transfer chamber, a plurality of sample holders are provided at intervals along the length direction of the conveyor belt, and a plurality of sample slots are provided on the sample holder at intervals along the width direction of the conveyor belt for placing sample boxes of different components. A rotating rod is rotatably connected to the top of the transfer chamber, and a plurality of rotating sleeves are rotatably connected to the rotating rod. A push plate is connected to the bottom end of the rotating sleeve, and a sensing surface is provided on the outer side of the rotating sleeve. A flushing rack is provided next to the sample rack, and a plurality of flushing positions are provided in the flushing rack.

[0007] The stand is erected on the detection table, and the top of the stand is connected to the sampling rack for horizontal sliding. The bottom of the sampling rack is connected to multiple samplers. A visual sensor and a rotating drum located below the visual sensor are fixed on the sampling rack. Multiple sensing positions and a perspective position are sequentially spaced along the outer circumference of the rotating drum. The sensing position is provided with a sensing surface identical to the outer side of the rotating sleeve. The liquid chromatograph is provided with multiple feed positions for purity detection of different components. In the initial state, the push plate is in an upright position, with the sensing surface facing the side end direction of the conveying bin and the perspective position facing upward. When the sampling rack slides to the top of the sample rack, the visual sensor detects the position of each rotating sleeve through the perspective position. If the sensing surface is not detected, the conveyor belt is triggered to move forward until the sample box moves forward and pushes the push plate to rotate so that the corresponding sensing surface rotates upward. When detected by the visual sensor, the corresponding sampler is triggered to descend for sampling. When the sampler moves up and resets, the rotating drum is pushed to rotate to switch to the next sensing position, and then the corresponding sampler is triggered to descend for sampling and flushing.

[0008] Preferably, a plurality of telescopic cylinders are provided at intervals on the sampling rack, and each sampler is connected to the bottom end of the telescopic cylinder.

[0009] Preferably, a pad is elastically connected to the sample groove. When the sample box storing the sample liquid is placed on the pad, the bottom end of the sample box is located in the sample groove and pushes the push plate at an eccentric position on the outside of the sample box. After the sampler takes samples, the sample box is elastically lifted by the pad and moved outside the sample groove.

[0010] Preferably, a gap is left between the front end of the conveying bin and the conveyor belt, and the sample boxes pushed out of the sample slot fall along the gap and are collected.

[0011] Preferably, the rotating sleeve is connected to a baffle on one side of its sensing surface. In the initial state, the baffle of the rotating sleeve faces the side end of the conveying bin. When the push plate rotates to rotate its sensing surface upward, the baffle blocks the sensing surface of the remaining rotating sleeve on the adjacent side.

[0012] Preferably, a protective cover is fixedly connected to the sampling frame, the protective cover is sleeved on the outside of the sampler, the visual sensor is fixed inside the protective cover, the end of the rotating drum is connected to the protective cover through the rotation of the drum shaft, a connecting rod is unidirectionally connected to the drum shaft, and a convex strip is vertically connected to the outer end of the sampler. During the descent of the sampler, the convex strip pushes the connecting rod downward to make the connecting rod rotate in one direction. During the ascent and resetting of the sampler, the convex strip pushes the connecting rod upward to drive the drum shaft to rotate, so that the rotating drum rotates to switch to the next sensing position.

[0013] Preferably, the plurality of flushing positions in the flushing rack are arranged at intervals along the length direction of the conveyor belt, and when the sampling rack moves above the flushing rack, the sampler moves above the corresponding flushing positions.

[0014] Preferably, the top of the vertical frame is laterally connected to a guide frame, the top of the guide frame is provided with a power frame parallel to the top of the guide frame, a guide groove is provided in the guide frame, the top of the sampling frame is connected to a hanging column, the top of the hanging column is inserted into the guide groove and fixedly connected to a guide block, the top of the guide block is rotatably connected to a power column, and an elastic member is provided at the rotating connection, the power column penetrates into the power frame, and is used to drive the sampling frame to move horizontally, and the guide groove is divided into a narrow groove section, a transition section and a wide groove section in sequence, the inner diameter of the wide groove section is larger than the inner diameter of the narrow groove section, the two ends of the transition section are respectively connected with the narrow groove section and the wide groove section, and a stop block is fixed in the wide groove section. When the guide block moves from the narrow groove section to the transition section, the elastic member drives the guide block to rotate, and when the guide block moves and abuts against the stop block, the stop block pushes the guide block to rotate, so that the sampler rotates to the corresponding flushing positions.

[0015] The present invention also provides a method for measuring the purity of the extracted soothing component, comprising the following steps:

[0016] Place the sample box into the sample slot. Select the corresponding sample slot on each sample holder and place a sample box in it. In the initial state, each push plate is upright, with the sensing surface facing the side of the transfer chamber, each perspective position facing upward and facing the visual sensor, and the sampling rack is located above the washing rack.

[0017] During operation, the sampling rack slides to the top of the sample rack, and the visual sensor detects the position of each rotary sleeve through the perspective position. If the sensing surface is not detected, the conveyor belt is triggered to move forward until the sample box moves forward and pushes the push plate to rotate so that the corresponding sensing surface rotates upward. When detected by the visual sensor, the corresponding sampler is triggered to descend for sampling. After sampling, the sampler moves up and resets, pushing the rotating drum to rotate and switch to the next sensing position upward. The sampling rack slides to the liquid chromatograph again, and also triggers the corresponding sampler to descend for sampling, and starts the corresponding purity test. After sampling, the sampler moves up and resets, and the sampling rack slides to the flushing rack again, and also triggers the corresponding sampler to descend for flushing. When the sampler moves up and resets after flushing, it pushes the rotating drum to rotate and reset so that its perspective position faces upward, completing continuous testing.

[0018] The beneficial effects of the present invention are as follows: by placing the sample box into the sample slot, selecting the corresponding sample slot on each sample holder and placing a sample box, the sampling rack slides to the top of the sample rack, and the visual sensor detects the position of each rotating sleeve through the perspective position. If the sensing surface is not detected, the conveyor belt is triggered to move forward until the sample box moves forward and pushes the push plate to rotate so that the corresponding sensing surface rotates upward. When detected by the visual sensor, the corresponding sampler is triggered to descend for sampling. After sampling, the sampler moves up and resets, pushing the rotating drum to rotate and switch to the next sensing position facing upward. The sampling rack slides to the liquid chromatograph again, and also triggers the corresponding sampler to descend for sampling, and starts the corresponding purity detection. After sampling, the sampler moves up and resets, and the sampling rack slides to the flushing rack again, and also triggers the corresponding sampler to descend for flushing. When the sampler moves up and reset after flushing, it pushes the rotating drum to rotate and reset so that its perspective position faces upward, completing continuous detection. The operation is simple and saves a lot of manual operation steps and working hours. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating drum 18 below the sensor 17 has a plurality of sensing positions 181 and a perspective position 182 arranged in sequence on the outer circumference of the rotating drum 18. The sensing position 181 is provided with a sensing surface identical to that on the outer side of the rotating sleeve 9. The liquid chromatograph 2 is provided with a plurality of feed positions 201 for purity detection of different components. In the initial state, the push plate 10 is in an upright position, the sensing surface faces the side end direction of the conveying bin 4, and the perspective position 182 faces upward. When the sampling rack 15 slides to above the sample rack 3, the visual sensor 17 detects the position of each rotating sleeve 9 through the perspective position 182. If the sensing surface is not detected, the conveyor belt 5 is triggered to move forward until the sample box 7 moves forward and pushes the push plate 10 to rotate so that the corresponding sensing surface rotates upward. When detected by the visual sensor 17, the corresponding sampler 16 is triggered to descend for sampling. When the sampler 16 moves up and resets, the rotating drum 18 is pushed to rotate to switch to the next sensing position 181, and then the corresponding sampler 16 is triggered to descend for sampling and flushing.

[0044] The present invention is based on the existing method and equipment for detecting the purity of soothing ingredients, including a detection table 1, a liquid chromatograph 2 for detecting the purity of ingredients is provided on the detection table 1, and a plurality of feed positions 201 are provided on the liquid chromatograph 2. For example, the existing liquid chromatography system can be equipped with at least one detector or detection position. When a certain amount of ingredients is put into the detector or detection position, the corresponding detection and analysis task is started for detecting the purity of different ingredients. The present invention also includes a sample rack 3 arranged beside the liquid chromatograph 2, a conveying bin 4 is provided on the sample rack 3, a conveyor belt 5 is provided in the conveying bin 4, a plurality of sample holders 6 are provided on the conveyor belt 5 at intervals along its length direction, a plurality of sample slots 61 are provided on the sample holder 6 at intervals along the width direction of the conveyor belt 5, and a plurality of sample slots 61 are provided on the top of the conveying bin 4 at intervals along the width direction of the conveyor belt 5. A rotating rod 8 is rotatably connected to the conveyor belt 5 in the width direction, and a plurality of rotating sleeves 9 are rotatably connected to the rotating rod 8 at intervals along its length direction. A push plate 10 is connected to the bottom end of the rotating sleeve 9, and a sensing surface is provided on the outside of the rotating sleeve 9. A flushing rack 11 is provided next to the sample rack 3, and a flushing trough 12 is provided at the top end of the flushing rack 11. A plurality of flushing positions 13 are provided in the flushing trough 12. A stand 14 is erected on the detection table 1, and a sampling rack 15 is connected to the top of the stand 14 for transverse sliding. A plurality of samplers 16 are connected to the bottom end of the sampling rack 15. A visual sensor 17 and a rotating drum 18 located below the visual sensor 17 are fixed on the sampling rack 15. A plurality of sensing positions 181 and a perspective position 182 are sequentially spaced in the circumferential direction of the outer side of the rotating drum 18. The sensing position 181 is provided with a rotation sensor. The same sensing surface on the outside of the sleeve 9, specifically, the feed position 201, the sample slot 61, the rotating sleeve 9, the flushing position 13, the sampler 16, the visual sensor 17, and the rotating drum 18 are all provided with three. Three sampling holes for sampling are opened on the front end of the transmission bin 4, and a hinged openable and closable lid is provided on the rear end of the transmission bin 4. When the component extracts are delivered to the testing laboratory in batches, the lid is opened and the sample box 7 containing the component extracts is placed in the sample slot 61. The corresponding sample slot 61 is selected on each sample holder 6 and a sample box 7 is placed therein. In the initial state, each push plate 10 is in an upright position, with the sensing surface facing the side end direction of the transmission bin 4, and each perspective position 182 is facing upward and facing the visual sensor 17. The sampling rack 15 is located above the flushing rack 11. When working, the sampling rack 15 slides When it reaches the top of the sample rack 3, the visual sensor 17 detects the position of each rotary sleeve 9 through the perspective position 182. If the sensing surface is not detected, the conveyor belt 5 is triggered to move forward until the sample box 7 moves forward and pushes the push plate 10 to rotate so that the corresponding sensing surface rotates upward. When it is detected by the visual sensor 17, the corresponding sampler 16 is triggered to descend for sampling. After sampling, the sampler 16 moves up and resets, pushing the rotating drum 18 to rotate and switch to the next sensing position 181 upward. The sampling rack 15 slides to the liquid chromatograph 2. Since the other two samplers 16 do not rise or fall, the visual sensor 17 thereon always faces the perspective position 182. Therefore, at the liquid chromatograph 2, the corresponding sampler 16 is also triggered to descend for sampling, and the corresponding purity detection is turned on. After sampling,The sampler 16 moves upward and resets, and the sampling rack 15 then slides to the flushing rack 11, which also triggers the corresponding sampler 16 to descend and flush. When the flushed sampler 16 moves upward and resets, it pushes the rotating drum 18 to rotate and reset, so that its perspective position 182 faces upward, and then the next round of continuous testing begins. The operation is simple and saves a lot of manual steps and work hours.

[0045] In an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 11 As shown, a plurality of telescopic cylinders 19 are provided at intervals on the sampling rack 15, and each sampler 16 is connected to the bottom end of the telescopic cylinder 19, respectively, for driving the sampler 16 to rise and fall. Specifically, the sampler 16 adopts the existing conventional syringe sampling equipment, and utilizes power components such as cylinders to drive the piston movement to realize the function of extracting and pushing out liquid materials, and the sampling and sample volume are more accurate than manual operation, which is conducive to more stable adaptation to the detection parameters of the liquid chromatograph 2, and outputs more stable and accurate detection values. Specifically, a one-way overflow valve can be provided at the bottom end of the sampling port of the sampler 16 to prevent the liquid material extracted in the sampler 16 from naturally leaking downward during the transportation process.

[0046] Preferably, a switch component electrically connected to the visual sensor 17 can also be provided at the top of the stand 14. When the sampling rack 15 moves to the position of the sample rack 3, the liquid chromatograph 2, and the flushing rack 11, the switch component is touched to energize the visual sensor 17 to avoid repeated detection and energy consumption during transportation. The visual sensor 17 is electrically connected to the telescopic cylinder 19 and the sampler 16 respectively. When the visual sensor 17 detects the sensing surface, the telescopic cylinder 19 and the sampler 16 are triggered to cooperate in sampling and placing.

[0047] Among them, the visual sensor 17 can adopt existing conventional scanning cameras, image recognition sensors, etc., and each sensing surface is provided with the same image. The top cover of the conveying bin 4 is made of transparent material, which is conducive to accurate detection and avoids human error.

[0048] In an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 11 As shown, a pad 62 is elastically connected to the sample tank 61. Specifically, the pad 62 can be elastically connected to the bottom end of the sample tank 61 by a spring or the like. The pad 62 itself can also be designed to be a conventional elastic component such as an elastic sponge. When the sample box 7 storing the sample liquid is placed on the pad 62, as shown in FIG. Figure 11 As shown, the cushion block 62 is naturally compressed so that the bottom end of the sample box 7 is located in the sample slot 61. On the one hand, it is conducive to stable storage. On the other hand, when the push plate 10 is pushed at the eccentric position on the outside of the sample box 7, the sample box 7 is not easy to separate from the sample slot 61, which is conducive to the stable rotation of the push plate 10. After the sampler 16 takes samples, the sample box 7 becomes lighter and is elastically lifted up by the cushion block 62 and moved to the outside of the sample slot 61. At this time, the sample box 7 is not enough to push the push plate 10, so that the push plate 10 turns to the initial upright state, and the sample box 7 moves forward with the conveyor belt 5. Specifically, there is a gap between the front end of the conveying bin 4 and the conveyor belt 5, and the sample box 7 pushed out of the sample slot 61 falls along the gap and is collected.

[0049] In an embodiment of the present invention, Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 As shown, the rotating sleeve 9 is connected to a stopper 20 on one side of its sensing surface. In the initial state, the stopper 20 of the rotating sleeve 9 is directed toward the side end of the transfer chamber 4. When the push plate 10 rotates to rotate its sensing surface upward, the stopper 20 blocks the sensing surface of the remaining rotating sleeve 9 on the adjacent side. Therefore, when manual operation is neglected and more than one sample box 7 is placed on the same sample holder 6, as shown in FIG. Figure 14 As shown, the baffle 20 rotates with the rotating sleeve 9, thereby blocking all the sensing surfaces on the side, so that the visual sensor 17 can only detect one sensing surface at a time and trigger sampling. After sampling, stocking, and rinsing, when the sampling rack 15 is moved to the top of the sample rack 3, as shown in FIG. Figure 15 As shown, the remaining sensing surfaces are sensed and the remaining sample boxes 7 are sampled until no sensing surface is detected, triggering the conveyor belt 5 to move forward, thereby avoiding sampling two sample boxes 7 at the same time and causing detection confusion.

[0050] In an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11As shown, a protective cover 21 is fixedly connected to the sampling frame 15, and the protective cover 21 is sleeved on the outside of the sampler 16. The visual sensor 17 is fixed in the protective cover 21 to play a protective role. The end of the rotating drum 18 is rotatably connected to the protective cover 21 through the cylinder shaft 180. The cylinder shaft 180 is unidirectionally rotatably connected with a connecting rod 22, that is, the connecting rod 22 can only be rotated downward in one direction, which can be achieved by various methods such as one-way hinges and one-way hinges. A raised rib 23 is vertically connected to the outer end of the sampler 16. During the descent of the sampler 16, as shown in FIG. Figure 8 As shown, the convex strip 23 pushes the connecting rod 22 downward to make the connecting rod 22 rotate downward in one direction. During the process of the sampler 16 rising and resetting, as shown in FIG. Figure 9 As shown, the convex strip 23 pushes the connecting rod 22 upward, driving the cylinder shaft 180 to rotate, so that the rotating cylinder 18 rotates to switch to the next sensing position 181 or perspective position 182. Figure 10 As shown, a bearing may be provided in the protective cover 21 for cooperating with the cylindrical shaft 180. A marble may be provided on the outside of the cylindrical shaft 180. Grooves are provided at circumferentially spaced positions on the inner ring of the bearing so that when the rotating drum 18 rotates, the marbles fall into the grooves and limit their positions, which is beneficial for the sensing position 181 or the perspective position 182 to stably face the visual sensor 17.

[0051] Specifically, such as Figure 7 、 Figure 8 、 Figure 9 As shown, the sensing position 181 or the perspective position 182 can be designed in the shape of a boss along the outer circumference of the rotating drum 18, wherein a conventional perspective mirror and other components can be set at the perspective position 182, and the perspective mirror can be symmetrically arranged along the upper and lower ends of the rotating drum 18, which is beneficial for the visual sensor 17 to see downward through the perspective mirror and the hollow rotating drum 18.

[0052] In an embodiment of the present invention, Figure 1 As shown, the multiple flushing positions 13 in the flushing rack 11 are spaced apart along the length direction of the conveyor belt 5. When the sampling rack 15 moves above the flushing rack 11, the sampler 16 rotates to the corresponding flushing positions 13, which is conducive to a more reasonable space layout.

[0053] Specifically, the flushing position 13 can be composed of a hollow movable column in the outer circle and a nozzle located in the middle of the hollow movable column. During flushing, the sampler 16 descends until it presses against the hollow movable column in the outer circle, so that the nozzle sprays pure water upward. The sewage after flushing is discharged outward along the gap between the hollow movable column and the nozzle, and the flushing trough 12.

[0054] In an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7、 Figure 11 、 Figure 17 、 Figure 18 、 Figure 19 As shown, the top of the stand 14 is laterally connected to a guide frame 24, and a power frame 25 is provided in parallel to the top of the guide frame 24. A guide groove 240 is provided in parallel in the guide frame 24. The top of the sampling frame 15 is connected to a hanging column 26, and the top of the hanging column 26 penetrates into the guide groove 240 and is fixedly connected to a guide block 27. The top of the guide block 27 is rotatably connected to a power column 28, and an elastic member is provided at the rotation connection. The elastic member can specifically adopt an existing conventional elastic member such as a torsion spring. A screw and a slider meshingly connected to the screw can be specifically provided in the power frame 25. The power column 28 penetrates into the power frame 25 and is connected to the slider. The drive component such as a reduction motor is used to drive the screw to rotate, thereby driving the power column 28 and the sampling frame 15 to move laterally. Figure 17 As shown, the guide groove 240 is divided into a narrow groove section 241, a transition section 242 and a wide groove section 243 in sequence. The inner diameter of the wide groove section 243 is larger than the inner diameter of the narrow groove section 241. The two ends of the transition section 242 are connected with the narrow groove section 241 and the wide groove section 243 respectively. The wide groove section 243 is fixed with a stopper 29. The guide block 27 can be specifically designed to be in the shape of a waist pill. The guide block 27 is attached to the narrow groove section 241 and slides. When it moves from the narrow groove section 241 to the transition section 242, as shown in FIG. Figure 18 As shown, the elastic member drives the guide block 27 to rotate. When the guide block 27 continues to move until it abuts against the stopper 29, the stopper 29 pushes the guide block 27 to rotate further, so that the sampler 16 is rotated to the state above the corresponding flushing position 13. On the contrary, the guide block 27 moves from the wide groove section 243 and the transition section 242 to the narrow groove section 241, as shown in FIG. Figure 19 As shown, the sampler 16 is turned to the state of sampling and stocking direction.

[0055] The present invention also provides a method for measuring the purity of the extracted soothing component, comprising the following steps:

[0056] Place the sample box 7 containing the component extract into the sample slot 61. Select the corresponding sample slot 61 on each sample holder 6 and place a sample box 7 therein. In the initial state, each push plate 10 is in an upright position, with the sensing surface facing the side end of the transfer chamber 4, each perspective position 182 facing upward and facing the visual sensor 17, and the sampling rack 15 is located above the washing rack 11.

[0057] During operation, the sampling rack 15 slides to the top of the sample rack 3, and the visual sensor 17 detects the position of each rotary sleeve 9 through the perspective position 182. If the sensing surface is not detected, the conveyor belt 5 is triggered to move forward until the sample box 7 moves forward and pushes the push plate 10 to rotate so that the corresponding sensing surface rotates upward. When detected by the visual sensor 17, the corresponding sampler 16 is triggered to descend for sampling. After sampling, the sampler 16 moves up and resets, pushing the rotating drum 18 to rotate and switch to the next sensing position 181 upward. The sampling rack 15 slides to the liquid chromatograph 2 again, and also triggers the corresponding sampler 16 to descend for sampling, and starts the corresponding purity detection. After sampling, the sampler 16 moves up and resets, and the sampling rack 15 slides to the flushing rack 11 again, and also triggers the corresponding sampler 16 to descend for flushing. When the flushed sampler 16 moves up and resets, it pushes the rotating drum 18 to rotate and reset so that its perspective position 182 faces upward, completing continuous detection.

[0058] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention is limited to these examples. Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
