Description

Technical Field

[0001] This application belongs to the field of fire extinguishing equipment technology, specifically relating to a multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing system and method for use with adhesive tape. Background Technology

[0002] Low-temperature resistant ultrafine dry powder fire extinguishing agents are widely used both domestically and internationally due to their low extinguishing concentration, rapid extinguishing speed, low-temperature resistance, high extinguishing efficiency, and green, environmentally friendly, and healthy characteristics. These agents primarily use ammonium polyphosphate as a base material. Factory buildings used for tape production and storage are required to be equipped with fire extinguishing systems. These factories typically have suspended fire extinguishing devices installed on the ceiling. Since tape factory buildings are often large, multiple suspended fire extinguishing devices are usually installed. Because the ceilings of tape factory buildings are typically high, the suspended fire extinguishing devices are generally installed at the lower end of the hanging brackets to achieve optimal fire extinguishing effect. However, due to the length of the hanging brackets themselves, the temperature sensing elements at the lower end of the suspended fire extinguishing device may be damaged by impact, thus affecting the normal operation of the device. Summary of the Invention

[0003] This application provides a multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing system and method specifically for adhesive tape, which solves the problem in the prior art where the temperature sensing element of a suspended fire extinguishing device installed at the lower end of a hanging bracket is damaged by impact.

[0004] To achieve the above objectives, embodiments of the present invention provide a multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing system for adhesive tape, including a cover, a telescopic sleeve, a motor, a rope wheel, a rotating mechanism, and a suspended fire extinguishing device;

[0005] The lower part of the cover is equipped with the telescopic sleeve, the motor is installed inside the cover, the output shaft of the motor is equipped with the rope winding wheel, the rope winding wheel is wound with a suspension rope, and the end of the suspension rope extends into the telescopic sleeve and is connected to the bottom wall of the telescopic tube at the lowest end of the telescopic sleeve.

[0006] The lower end of the telescopic sleeve is equipped with the rotating mechanism, and two or more of the suspended fire extinguishing devices are evenly distributed around the circumference of the rotating mechanism; a temperature sensing element is provided at the nozzle of the suspended fire extinguishing device.

[0007] When two or more of the suspended fire extinguishing devices rotate, they form a virtual circle, and the nozzles of the two or more suspended fire extinguishing devices are arranged clockwise according to the virtual circle.

[0008] In one possible implementation, two or more of the suspended fire extinguishing devices are arranged in a centrally symmetrical manner with respect to the rotation center of the rotating mechanism;

[0009] Each of the suspended fire extinguishing devices is equipped with two nozzles, and the tangent of the virtual circle at the center of the suspended fire extinguishing device is taken as the axis of symmetry.

[0010] The two nozzles are arranged symmetrically about the axis of symmetry; one nozzle is arranged downward, outward and backward, and the other nozzle is arranged downward, inward and backward.

[0011] In one possible implementation, the temperature-sensing elements of two or more of the suspended fire extinguishing devices are interconnected via temperature-sensing wires.

[0012] In one possible implementation, the rotating mechanism includes a housing, a central plate, a rotating shaft, a push bearing, a disc, a cylindrical roller bearing, and a telescopic rod;

[0013] The housing is installed at the lower end of the telescopic sleeve. The center plate is provided inside the housing. The upper end of the rotating shaft extends into the interior of the housing and passes through the center plate. The rotating shaft and the center plate are fixedly connected. The center plate is provided with push bearings at both the upper and lower parts. The rotating shaft passes through the push bearings. The cylindrical roller bearings are provided between the rotating shaft and the top and bottom walls of the housing.

[0014] The lower end of the rotating shaft is connected to the disc, and two or more telescopic rods are evenly distributed around the circumference of the disc. Each of the two or more telescopic rods corresponds to one or more suspended fire extinguishing devices, and the top of the suspended fire extinguishing device is connected to the end of the telescopic rod.

[0015] In one possible implementation, an unlocking mechanism is also included, which comprises a locking rope, a rotating column, and a cutter;

[0016] The telescopic sleeve is initially in a retracted state, and the end of the suspension rope is connected to a fixing block on the bottom wall of the telescopic sleeve at the lowest end. The suspension rope is in a slack state.

[0017] The upper end of the locking rope is fixed to the top wall of the cover body, and the lower end of the locking rope extends into the telescopic sleeve and is connected to the bottom wall of the telescopic tube at the lowest end of the telescopic sleeve. The locking rope is in a tensioned state.

[0018] The rotating column is rotatably installed at the center of the bottom wall of the telescopic tube at the lowest end of the telescopic sleeve. The lower end of the rotating column is fixed to the top of the rotating shaft. The upper side wall of the rotating column is provided with the cutter. The cutting edge of the cutter is located on the side away from the locking rope at the center of the cutter. The locking rope and the cutter are arranged in sequence according to the rotation direction of the rotating column.

[0019] In one possible implementation, a pressurization mechanism is also included, which comprises a compressed gas cylinder, a balance tube, a spring, a magnetic drive block, a flexible sealing sheet, a magnetic driven block, and a sealing plate.

[0020] The upper part of the cylinder body of the suspended fire extinguishing device is provided with the compressed gas cylinder, and the compressed gas cylinder is provided with compressed nitrogen.

[0021] The balance tube is vertically installed on the inner wall of the bottle. The lower end of the balance tube is provided with an air inlet, which is connected to the inside of the bottle. The upper part of the balance tube is provided with an exhaust port that is connected to the outside atmosphere. The spring, the magnetic drive block, and the flexible sealing sheet are arranged sequentially from top to bottom inside the balance tube. The flexible sealing sheet is circumferentially sealed to the inner wall of the balance tube.

[0022] The magnetic driven block is mounted on the balance tube. Both the magnetic driven block and the magnetic driving block are magnetic, and they are connected by magnetic force.

[0023] The lower part of the compressed gas cylinder is provided with an exhaust port, and the upper part of the magnetic drive block is provided with a sealing plate, the upper surface of the sealing plate abutting against the exhaust port of the compressed gas cylinder.

[0024] In one possible implementation, the pressurization mechanism further includes a fixed cylinder, a telescopic column, and an elastic block;

[0025] The elastic block is disposed on the bottom wall inside the fixed cylinder. The lower end of the telescopic column extends into the fixed cylinder and abuts against the elastic block. The fixed cylinder and the magnetic driven block are connected. The upper end of the telescopic column is connected to the lower surface of the sealing plate.

[0026] This invention also provides a method for extinguishing fires with multi-dimensional low-temperature resistant ultrafine dry powder specifically for adhesive tape, which uses the above-mentioned multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing system specifically for adhesive tape and includes the following steps;

[0027] When a fire occurs, the temperature sensing element of the suspended fire extinguishing device detects the fire signal, causing the nozzle of the suspended fire extinguishing device to spray fire extinguishing agent to extinguish the fire. At the same time, it controls the telescopic sleeve to extend to the set length, thereby driving the rotating mechanism and the suspended fire extinguishing device to move down to the set position.

[0028] The extinguishing agent produced by the two nozzles of the suspended fire extinguishing device is sprayed downward and backward simultaneously, causing two or more suspended fire extinguishing devices to rotate around the rotation center of the rotating mechanism. The extinguishing agent produced by the two nozzles of the suspended fire extinguishing device is sprayed to both sides of the suspended fire extinguishing device, thereby covering the inner and outer sides of the virtual circle below.

[0029] In one possible implementation, when two or more suspended fire extinguishing devices rotate around the rotation center of the rotating mechanism, the rotating shaft of the rotating mechanism drives the rotating column to rotate. When the rotating column rotates nearly one revolution, the cutter cuts the locking rope. After the telescopic sleeve releases the locking rope, the telescopic sleeve extends under the action of gravity until the suspension rope is taut.

[0030] In one possible implementation, the following process repeatedly occurs during the continuous fire suppression process of the suspended fire extinguishing device:

[0031] As the pressure inside the bottle gradually decreases, the magnetic drive block moves downward, causing the magnetic driven block to move downward, thus separating the sealing plate from the exhaust port. Nitrogen gas from the compressed gas cylinder enters the bottle, causing the pressure inside the bottle to gradually increase. This causes the magnetic drive block to move upward, causing the magnetic driven block to move upward, thus sealing the exhaust port with the sealing plate.

[0032] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0033] This invention provides a multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing system and method specifically for adhesive tape. In the initial state, the telescopic sleeve is in a retracted state, so the system is located at a high position on the ceiling of the adhesive tape factory. When normally suspended, the temperature sensing element at the lower end of the suspended fire extinguishing device is not susceptible to damage from collisions. In the event of a fire, the suspended fire extinguishing device moves down to a set height to achieve a better fire extinguishing effect. By rotating the suspended fire extinguishing device to spray the extinguishing agent, the fire extinguishing range can be increased, thereby further improving the fire extinguishing effect.

Detailed Implementation

[0041] 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, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the description of the embodiments of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the embodiments of the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0043] like Figures 1 to 5As shown in the figure, the multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing system for tape provided in this embodiment of the invention includes a cover 1, a telescopic sleeve 2, a motor 3, a rope wheel 4, a rotating mechanism 6, and a suspended fire extinguishing device 7.

[0044] A telescopic sleeve 2 is installed at the lower part of the cover 1. A motor 3 is installed inside the cover 1. A rope wheel 4 is installed on the output shaft of the motor 3. A suspension rope 5 is wound on the rope wheel 4. The end of the suspension rope 5 extends into the telescopic sleeve 2 and is connected to the bottom wall of the telescopic tube at the lowest end of the telescopic sleeve 2.

[0045] A rotating mechanism 6 is installed at the lower end of the telescopic sleeve 2, and two or more suspended fire extinguishing devices 7 are evenly distributed around the circumference of the rotating mechanism 6. A temperature sensing element 72 is installed at the nozzle 71 of the suspended fire extinguishing device 7.

[0046] When two or more suspended fire extinguishing devices 7 rotate, they form a virtual circle, and the nozzles 71 of the two or more suspended fire extinguishing devices 7 are all arranged clockwise according to the virtual circle.

[0047] It should be noted that the temperature sensing element 72 can be either a smoke and heat detector or a temperature sensing element bulb. Smoke and heat detectors are easier to integrate into control systems for remote real-time management. Temperature sensing element bulbs use a physical detection method, offering advantages such as fast response and reduced malfunction.

[0048] When the motor 3 drives the rope wheel 4 to rotate, it can drive the telescopic tube at the bottom of the telescopic sleeve 2 to move, thereby realizing the extension action of the telescopic sleeve 2. The telescopic sleeve 2 adopts a multi-section square tube structure.

[0049] In this embodiment, two or more suspended fire extinguishing devices 7 are arranged symmetrically about the rotation center of the rotating mechanism 6.

[0050] Each suspended fire extinguishing device 7 is equipped with two nozzles 71, and the tangent of the virtual circle at the center of the suspended fire extinguishing device 7 is taken as the axis of symmetry.

[0051] The two nozzles 71 are arranged symmetrically about an axis of symmetry. One nozzle 71 is positioned downward, outward, and backward, while the other nozzle 71 is positioned downward, inward, and backward.

[0052] It should be noted that, as Figure 3 The downward-facing nozzle 71 is primarily aimed at the burning facility below it. The rearward-facing nozzle 71 mainly provides thrust to rotate the suspended fire extinguishing device 7. The outward and inward-facing nozzles 71 direct the extinguishing agent towards the inner and outer areas of a virtual circle. Therefore, the nozzle 71's arrangement allows the extinguishing agent sprayed from two or more suspended fire extinguishing devices 7 to rotate around the rotation center of the rotating mechanism 6, achieving a larger extinguishing range and improving the fire extinguishing effect.

[0053] In this embodiment, the temperature sensing elements 72 of two or more suspended fire extinguishing devices 7 are interconnected through temperature sensing wires 10.

[0054] It should be noted that when one of the temperature sensing elements 72 detects a fire, the fire signal can be transmitted to other temperature sensing elements 72 via the temperature sensing wire 10, thereby simultaneously activating multiple suspended fire extinguishing devices 7 for fire suppression. This avoids the problems of some temperature sensing elements 72 activating slowly, resulting in untimely fire suppression, and the suspended fire extinguishing devices 7 failing to rotate, leading to poor fire suppression effects.

[0055] In this embodiment, the rotating mechanism 6 includes a housing 61, a center plate 62, a rotating shaft 63, a push bearing 64, a disc 65, a cylindrical roller bearing 66, and a telescopic rod 67.

[0056] The housing 61 is installed at the lower end of the telescopic sleeve 2. A center plate 62 is provided inside the housing 61. The upper end of the rotating shaft 63 extends into the interior of the housing 61 and passes through the center plate 62. The rotating shaft 63 and the center plate 62 are fixedly connected. A push bearing 64 is provided at both the upper and lower parts of the center plate 62. The rotating shaft 63 passes through the push bearing 64. A cylindrical roller bearing 66 is provided between the rotating shaft 63 and the top and bottom walls of the housing 61.

[0057] The lower end of the rotating shaft 63 is connected to the disc 65. Two or more telescopic rods 67 are evenly distributed around the disc 65. The two or more telescopic rods 67 correspond one-to-one with two or more suspended fire extinguishing devices 7. The top of the suspended fire extinguishing device 7 is connected to the end of the telescopic rod 67.

[0058] It should be noted that the installation of the push bearing 64 and the cylindrical roller bearing 66 reduces the frictional force when the shaft 63 rotates, thereby allowing the suspended fire extinguishing device 7 to rotate smoothly. The telescopic rod 67 facilitates the adjustment of the rotation radius of the suspended fire extinguishing device 7, thereby adjusting the fire extinguishing range.

[0059] In this embodiment, an unlocking mechanism 9 is also included, which includes a locking rope 91, a rotating column 92, and a cutter 93.

[0060] In the initial state, the telescopic sleeve 2 is in a retracted state, and the end of the suspension rope 5 is connected to the fixing block on the bottom wall of the telescopic tube at the lowest end of the telescopic sleeve 2, and the suspension rope 5 is in a slack state.

[0061] The upper end of the locking rope 91 is fixed to the top wall inside the cover 1, and the lower end of the locking rope 91 extends into the telescopic sleeve 2 and is connected to the bottom wall inside the telescopic tube at the lowest end of the telescopic sleeve 2. The locking rope 91 is in a tensioned state.

[0062] The rotating column 92 is rotatably installed at the center of the bottom wall of the telescopic tube at the lowest end of the telescopic sleeve 2. The lower end of the rotating column 92 is fixed to the top of the rotating shaft 63. A cutter 93 is provided on the upper side wall of the rotating column 92. The cutting edge of the cutter 93 is located on the side of the cutter 93 away from the locking rope 91. The locking rope 91 and the cutter 93 are arranged in sequence according to the rotation direction of the rotating column 92.

[0063] It should be noted that, in the initial state, the telescopic sleeve 2 remains retracted under the pull of the locking rope 91. When the cutting blade 93 rotates nearly one revolution with the rotating column 92, the cutting edge of the cutting blade 93 begins to contact and cut the locking rope 91 until the locking rope 91 is cut. After the locking rope 91 is cut, the telescopic sleeve 2 quickly extends to the set length under the action of gravity, thereby adjusting the suspended fire extinguishing device 7 to the optimal fire extinguishing height. A shock-absorbing spring 83 can also be installed at the connection of the telescopic sleeve 2 to buffer the impact when the telescopic sleeve falls. By extending the telescopic sleeve 2 in this way, the time taken for the telescopic sleeve 2 to extend can be shortened, thereby achieving the purpose of timely fire extinguishing. At the same time, this structure is simple and easy to maintain. The locking rope 91 is cut only when the rotating column 92 rotates nearly one revolution, that is, when the suspended fire extinguishing device 7 rotates nearly one revolution, thus avoiding the problem of the telescopic sleeve 2 extending due to accidental shaking of the suspended fire extinguishing device 7 or small-angle rotation.

[0064] In this embodiment, a pressurizing mechanism 8 is also included. The pressurizing mechanism 8 includes a compressed gas cylinder 81, a balance tube 82, a spring 83, a magnetic drive block 84, a flexible sealing sheet 85, a magnetic driven block 86, and a sealing plate 87.

[0065] The upper part of the cylinder body 73 of the suspended fire extinguishing device 7 is equipped with a compressed gas cylinder 81, which is filled with compressed nitrogen.

[0066] The balance tube 82 is vertically installed on the inner wall of the bottle body 73. The lower end of the balance tube 82 is provided with an air inlet, which is connected to the inside of the bottle body 73. The upper part of the balance tube 82 is provided with an exhaust port that is connected to the outside atmosphere. From top to bottom, the balance tube 82 is provided with a spring 83, a magnetic drive block 84, and a flexible sealing sheet 85. The flexible sealing sheet 85 is circumferentially sealed to the inner wall of the balance tube 82.

[0067] A magnetic follower block 86 is mounted on the balance tube 82. Both the magnetic follower block 86 and the magnetic drive block 84 are magnetic, and they are connected by magnetic force.

[0068] The lower part of the compressed gas cylinder 81 is provided with an exhaust port, and the upper part of the magnetic drive block 84 is provided with a sealing plate 87, the upper surface of the sealing plate 87 abutting against the exhaust port of the compressed gas cylinder 81.

[0069] It should be noted that the two ends of the spring 83 are respectively connected to the top wall of the balance tube 82 and the upper surface of the magnetic drive block 84. The flexible sealing plate 85 plays a sealing role to prevent the compressed gas in the bottle 73 from leaking out. When the suspended fire extinguishing device 7 is not in use, the pressure in the bottle 73 keeps the magnetic drive block 84 at a set height, keeps the magnetic driven block 86 at a set height, and thus makes the upper surface of the sealing plate 87 abut against the exhaust port of the compressed gas bottle 81. An upper limit block can also be provided on the inner wall of the balance tube 82. The lower surface of the upper limit block abuts against the upper surface of the magnetic drive block 84. The upper limit block can prevent the magnetic drive block 84 from moving too high and causing the magnetic driven block 86 to detach from the magnetic drive block 84. A lower limit block can also be provided at the lower end of the outer wall of the balance tube 82. The lower limit block prevents the magnetic driven block 86 from detaching from the balance tube 82.

[0070] The thrust exerted by the gas output from the exhaust port of the compressed gas cylinder 81 on the sealing plate 87 can be calculated using the formula of pressure, force and area, ensuring that the magnetic force formed by the magnetic driven block 86 and the magnetic driving block 84 is greater than the thrust generated by the gas, thereby avoiding the problem of continuous gas leakage.

[0071] The bottle body 73 and the compressed gas bottle 81 can be made of aluminum to ensure that the magnetic driven block 86 and the magnetic driving block 84 slide normally.

[0072] In this embodiment, the pressurization mechanism 8 also includes a fixed cylinder 88, a telescopic column 89, and an elastic block 810.

[0073] The elastic block 810 is disposed on the bottom wall inside the fixed cylinder 88. The lower end of the telescopic column 89 extends into the fixed cylinder 88 and abuts against the elastic block 810. The fixed cylinder 88 is connected to the magnetic driven block 86. The upper end of the telescopic column 89 is connected to the lower surface of the sealing plate 87.

[0074] It should be noted that when the upper surface of the sealing plate 87 comes into contact with the exhaust port of the compressed gas cylinder 81, the elastic block 810 is compressed, thereby improving the sealing effect.

[0075] like Figures 1 to 5 As shown in the figure, the multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing method for tape provided in this embodiment of the invention adopts the above-mentioned multi-dimensional low-temperature resistant ultrafine dry powder fire extinguishing system for tape and includes the following steps.

[0076] When a fire occurs, the temperature sensing element 72 of the suspended fire extinguishing device 7 detects the fire signal, causing the nozzle 71 of the suspended fire extinguishing device 7 to spray fire extinguishing agent to extinguish the fire. At the same time, it controls the telescopic sleeve 2 to extend to the set length, thereby driving the rotating mechanism 6 and the suspended fire extinguishing device 7 to move down to the set position.

[0077] The extinguishing agent generated by the two nozzles 71 of the suspended fire extinguishing device 7 is sprayed downward and backward simultaneously, causing two or more suspended fire extinguishing devices 7 to rotate around the rotation center of the rotating mechanism 6. The extinguishing agent generated by the two nozzles 71 of the suspended fire extinguishing device 7 is sprayed to both sides of the suspended fire extinguishing device 7, thereby covering the inner and outer sides of the virtual circle below.

[0078] It should be noted that the telescopic sleeve 2 can also be extended by being driven by the motor 3. In the initial state, the telescopic sleeve 2 is in a retracted state. Therefore, the system is located at a high position on the ceiling of the conveyor belt factory. When it is normally suspended, the temperature sensing element at the lower end of the suspended fire extinguishing device 7 will not be damaged by collision. In the event of a fire, the suspended fire extinguishing device 7 moves down to a set height to achieve a better fire extinguishing effect. By rotating the suspended fire extinguishing device 7 to spray the extinguishing agent, the fire extinguishing range can be increased, thereby further improving the fire extinguishing effect.

[0079] In this embodiment, when two or more suspended fire extinguishing devices 7 rotate around the rotation center of the rotating mechanism 6, the rotating shaft 63 of the rotating mechanism 6 drives the rotating column 92 to rotate. When the rotating column 92 rotates nearly one revolution, the cutter 93 cuts the locking rope 91. After the telescopic sleeve 2 releases the locking rope 91, the telescopic sleeve 2 extends under the action of gravity until the suspension rope 5 is in a taut state.

[0080] It should be noted that after the fire extinguishing duration is set, the control motor 3 starts, which drives the rope wheel 4 to rotate, thereby raising the suspended fire extinguishing device 7 to the set height via the hoisting rope 5. Then, a new locking rope 91 is installed to fix the position of the telescopic sleeve 2.

[0081] The present invention achieves the extension of the telescopic sleeve 2 by rotating and cutting the locking rope 91 of the suspended fire extinguishing device 7. This control method is reasonable and reliable, avoiding the problem of complicated operation steps caused by the need for continuous power supply to the electronic components to drive the device. The method is highly practical and easy to promote and use.

[0082] In this embodiment, the following process repeatedly occurs during the continuous fire extinguishing process of the suspended fire extinguishing device 7:

[0083] The pressure inside the bottle 73 gradually decreases, causing the magnetic drive block 84 to move downwards. The magnetic drive block 84 drives the magnetic driven block 86 to move downwards, causing the sealing plate 87 to separate from the exhaust port. Nitrogen gas from the compressed gas bottle 81 enters the bottle 73, causing the pressure inside the bottle 73 to gradually increase. This causes the magnetic drive block 84 to move upwards, and the magnetic drive block 84 drives the magnetic driven block 86 to move upwards, causing the sealing plate 87 to block the exhaust port.

[0084] It should be noted that during the fire extinguishing process, the sealing plate 87 moves repeatedly, allowing nitrogen gas to continuously enter the cylinder 73. This maintains a constant pressure within the cylinder 73, ensuring that the suspended fire extinguishing device 7 maintains its set rotation speed and preventing insufficient pressure within the cylinder 73 from affecting the fire extinguishing effect. Under this maintained pressure, the extinguishing agent can also be fully discharged, thus guaranteeing the fire extinguishing effect.

[0085] In this embodiment, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the present invention.
