Description

Technical Field

[0001] The invention belongs to the technical field of fishery information collection and analysis, and in particular relates to an automatic collection and classification device for fish catch information and a method thereof. Background Art

[0002] Catch refers to the fish, shrimp, crab, cephalopods, and other products caught by professional fishermen using various fishing gear. Currently, fishermen generally estimate their catch by counting the number of baskets containing a particular type of fish, multiplying this by the average basket weight of that catch, and so on for all other catches, to arrive at the total weight of the catch.

[0003] In the current fishing process, the processing of catches is very extensive. Fishermen usually do not collect and report catch information in a timely manner. As for the classification and processing of catches, they usually rely on experience and use manual processing methods to classify and store catches of different sizes and types. This method is not only manpower-consuming, but also occupies valuable manpower and fishing time, which greatly affects the efficiency of fishing.

[0004] Moreover, different catches have different processing and preservation methods, requiring different tools and storage environments. When catch information is difficult to obtain in a timely manner, it is difficult for the docking personnel and consignee merchants on the shore to make corresponding preparations in advance. This can easily cause some catches to be wasted due to the lack of corresponding storage tools and environment, resulting in improper storage.

[0005] In addition, each fishing area usually conducts a survey of fishery resources at sea, and analyzes and judges the marine fishery environment by comprehensively collecting information on the catch, so that corresponding measures can be taken in a timely manner when problems arise to reduce the losses of fishermen; but under normal circumstances, it is difficult to collect more abundant information in a timely and comprehensive manner by relying solely on a small number of official survey ships.

[0006] There is a lack of monitoring methods for fishing boats, and they can only rely on oral surveys of returning fishermen. The information obtained in this way is prone to large errors. Simply photographing the piles of catch gathered on the boat, even if special identification equipment is used to collect information on the type of catch in the picture data, the catch inside the pile cannot be effectively identified and its information collected in a timely manner. This makes it difficult to collect more comprehensive catch information, which is not conducive to the official fishery department to take corresponding measures in a timely manner, so as to better protect and utilize fishery resources and safeguard the interests of fishermen.

[0025] A method for automatically collecting and classifying catch information, wherein the method uses the aforementioned automatic collection and classification device for catch information, and the specific steps of the method are as follows:

[0026] S1: The automatic catch information collection and classification device is installed on a sailing fishing boat. During the fishing process, after the catch is caught in the fishing net, the fishing net is dragged by a winch, thereby pulling the fishing net close to the feed port until the catch is put into the feed port; after the catch enters the working body, it falls onto the transport roller;

[0027] S2: The intelligent control terminal starts the motor connected to the transport roller, causing the transport roller to rotate. The accumulated catches are moved by the transport roller.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. The device and method for automatically collecting and classifying fish catch information described in the present invention uses a collection camera inside a working body to more comprehensively capture dispersed fish catch information and transmit the information to an information analysis module, thereby analyzing the specific species and the proportion of the species in the number of fish catches in the image data. This facilitates fishery resource surveyors to determine the status of various fishery resources in the entire sea area by counting the harvest status of different types of fish by a large number of fishermen. In this way, timely measures such as releasing certain types of fish fry or restricting the fishing of certain types of fish can be taken to better protect and utilize fishery resources.

[0032] The device and method for automatically collecting and classifying catch information described in the present invention enable fishermen to more accurately judge the quantity of different types of catches by collecting and identifying catch information, and prepare collection boxes with different labels for different types of catches. In this way, in the subsequent manual screening process, catches that do not meet the labels can be directly screened out from the collection boxes, effectively reducing the time and energy consumed in screening and improving screening efficiency.

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] Example 1:

[0046] A device for automatically collecting and classifying fish catch information, as shown in the accompanying drawings of the specification Figure 2-3As shown, in order to improve the classification efficiency of fish catches, thereby improving the fishing efficiency of fishermen; better protect and utilize fishery resources and safeguard the interests of fishermen; the present application proposes a device for automatically collecting and classifying fish catch information, including an information collection unit 1, an information management unit and a classification work unit 2. The information collection unit 1 includes a collection camera 11 and an information analysis module. The collection camera 11 adopts a special instrument for existing fishery resource surveys, and can effectively identify the appearance characteristics of different types of fish catches by photographing the catches, such as color and shape, and then transmit the data to the information analysis module. The information analysis module here adopts a computer device that can effectively process data. For small fishing boats that are difficult to carry, the information can be transmitted to an onshore processing center via a wireless Bluetooth network. By comparing the pre-stored characteristic information of different types of fish catches, the specific type is analyzed, and the proportion of the type in the number of fish catches in the image data can also be calculated. The data is then transmitted to the information management unit;

[0047] The information management unit includes a big data sharing platform that can transmit catch information to relevant groups such as fishery staff and customers. Different types of people will take different measures, improving the efficiency of information circulation in the process. This allows people at different links in the catch flow to take different corresponding measures, reducing catch waste and improving the efficiency of catch classification and processing and fishing efficiency.

[0048] The classification work unit 2 is used to classify and preserve the harvested fish. The classification work unit 2 includes a working body 21, a support base 22, a feed port 23, and a discharge port 24. The feed port 23 is arranged on one side of the working body 21, and a winch 231 is arranged on the side wall of the feed port 23. The winch 231 here can be connected to the connecting rope of the fishing net, which is convenient for dragging the fishing net close to the feed port 23. After cleaning the garbage and debris in the net, the fish is put into the feed port 23; the discharge port 24 is arranged on the other side of the working body 21, and a top cover is provided on the discharge port 24, which is convenient for opening the top cover to take out the processed fish.

[0049] Transport rollers 25 are evenly arranged inside the working body 21. The ends of the transport rollers 25 are connected to motors provided on the side walls of the working body 21. The motors are controlled by an intelligent control terminal mounted on the working body 21. The intelligent control terminal adjusts the operation of each component according to a pre-set program under the operation of the operator. The working transport rollers 25 are used to transport the catch from the feed port 23 to the discharge port 24 and to disperse the catch. This facilitates the collection camera 11 installed inside the working body 21 to take a more comprehensive picture of the catch dispersed on the transport rollers 25.

[0050] Specific working process: During use, the device of the present application can be installed on a sailing fishing boat. Then, during the fishing process, after the fishing net catches the catch, the fishing net is dragged by the winch 231, thereby pulling the fishing net close to the feed port 23 until the catch is put into the feed port 23; after the catch enters the interior of the working body 21, it falls on the transport roller 25, and the intelligent control terminal starts the motor connected to the transport roller 25, causing the transport roller 25 to rotate, and the piled catch moves under the driving action of the transport roller 25. During this process, the catch is pushed by friction on different transport rollers 25, and is also subjected to vibration when passing through the gaps between different transport rollers 25, so that the piled catch is dispersed and spread out, and slowly moves with the slowly rotating transport roller 25:

[0051] In this way, the collection camera 11 located inside the working body 21 can capture the dispersed catch information more comprehensively. By capturing the catch, the characteristics of different types of catch, such as color and shape, can be effectively identified. The data is then transmitted to the information analysis module. The information analysis module compares the different types of catch stored in advance to analyze the specific type and the proportion of the type in the number of catches in the image data, and transmits the data to the information management unit.

[0052] The big data sharing platform on the information management unit can transmit catch information to different relevant groups of people, such as fishermen who are fishing, docking personnel and consignees on the shore, and fishery resource surveyors. Different types of people will take different measures. Docking personnel and consignees on the shore can determine the proportion of different types of catch based on the catch information, and thus prepare tools and processing personnel corresponding to different types of catch, and contact and prepare different storage tools, thereby reducing the waste of resources caused by poor information communication; fishery resource surveyors can determine the status of various fishery resources in the entire sea area by counting the harvest status of different types of catch by a large number of fishermen. In this way, they can take timely measures such as releasing certain types of fish fry or restricting the fishing of certain types of catch to better protect and utilize fishery resources;

[0053] For the fishermen on one side of the working body 21, they can estimate the harvest based on the catch information and their own experience. Compared with estimating based on experience alone, they can more accurately judge the number of different types of catches, so that different tools can be prepared in advance. For example, when the number of a certain type of catch in a certain net is relatively large, a collection box 3 can be prepared in advance. After the discharge port 24 is opened to collect the catch into the collection box 3, the collection box 3 is labeled to indicate a certain type of catch. When the same situation is encountered later, it is directly added to the collection box 3 with the label. When another type is encountered, another collection box 3 is prepared and labeled. In this way, in the subsequent manual screening process, the catch that does not meet the label can be directly screened out from the collection box 3. This can reduce the time and energy spent on screening and improve screening efficiency.

[0054] In addition, for certain species that require special preservation tools and are of greater value, tools can be prepared in advance or shore personnel can be notified to deliver them in a timely manner to reduce losses. Furthermore, fishermen can also roughly estimate their harvest based on the calculated number of catch types and the prices of different catches in the market listed on the sharing platform, so as to more reasonably adjust subsequent fishing plans, reduce wasted time, and improve fishing efficiency.

[0055] Example 2:

[0056] Based on the first embodiment, as shown in the accompanying drawings of the specification Figure 2-5 As shown, a plurality of classification areas 26 are provided in the portion below the transport rollers 25 within the working body 21, with partitions 261 provided between the classification areas 26; a classification opening 262 is provided at the bottom of the classification area 26, and a collection frame 3 is also provided below the classification opening 262; the gap widths between the transport rollers 25 above different classification areas 26 are different, and the sizes of the transport rollers 25 are also different. Moreover, the gap widths between the transport rollers 25 in different classification areas 26 are inversely proportional to the distance to the discharge port 24, thereby effectively screening catches of different sizes and improving the efficiency of fishermen in screening catches;

[0057] Specific work flow: Based on the specific work flow in Example 1, the value of fish of different individual sizes varies greatly. In order to more effectively classify the fish entering the working body 21, the gap width of the transport rollers 25 corresponding to different classification areas 26 is adjusted, so that fish of different individual sizes can be effectively classified, thereby improving the efficiency of subsequent manual processing; after the fish enters the working body 21, under the pushing action of the transport rollers 25, on the one hand, the scattered fish can be better photographed and identified by the collection camera 11, and the fish information is collected more comprehensively; on the other hand, during the movement of the fish, the gap between the transport rollers 25 passing through the fish continues to increase, so that fish of different sizes will pass through the gap between the transport rollers 25 with different gaps and enter the corresponding classification area 26, until the largest fish enters the last classification area 26 without a transport roller 25, and the largest individual fish left will fall directly into it, located on the side of the discharge port 24, and the discharge port 24 can be directly opened to take out the largest part of the individual fish;

[0058] Through the above process, fish of different sizes can be collected into different classification areas 26. The first classification area 26 contains the smallest fish, which may also be mixed with garbage and debris left when the fish are placed in the working body 21. Therefore, after observing that there are no high-value fish in the first classification area 26, fishermen can choose to directly discharge them into the sea, which is beneficial to the subsequent development of the fishery.

[0059] The subsequent catches of different sizes can be collected through different collection boxes 3 after the classification port 262 is opened, and the collection boxes 3 are numbered to indicate the order of the individual sizes of the catches in the entire catch, so that different processing methods can be adopted. Because the individual is related to the value, for catches of different types with similar market prices, they can even be processed directly without further classification, and the catches of similar individual sizes can be processed together, which also speeds up the efficiency of subsequent manual screening.

[0060] Example 3:

[0061] Based on the second embodiment, as shown in the accompanying drawings of the specification Figure 2-8 As shown, because the catches are entangled with each other during the harvesting process and the mucus on the surface of the catches adheres to each other, they may not be dispersed normally. Excessive aggregation makes it difficult for the collection camera 11 to accurately identify them, affecting the accuracy of the catch information collection; therefore, a dispersion module 4 is provided on the side wall of the working body 21 to assist in the dispersion and transportation of the catches on the transport roller 25; the dispersion module 4 includes a first telescopic device 41, which is horizontally installed on the inner wall of the working body 21. Here, the first telescopic device 41 can be an automatic telescopic device such as an electric telescopic rod;

[0062] A working roller 42 is provided on the telescopic end of the first telescopic device 41. The working roller 42 is located above the transport roller 25. A dispersion rod 43 is provided at the bottom of the working roller 42. The dispersion rod 43 is an arc-shaped structure and is connected to the outer surface of the working roller 42 through a connecting rod. Vertical dispersion columns 44 are evenly distributed at the bottom of the dispersion rod 43. The ends of the dispersion columns 44 are spherical structures.

[0063] Specific workflow: Based on the specific workflow in Example 2, when the acquisition camera 11 detects that the catch is too aggregated, the intelligent control terminal directly controls the activation of the No. 1 telescopic device 41. The activated No. 1 telescopic device 41 drives the working roller 42 to move back and forth laterally in a direction parallel to the transport roller 25. During this process, the laterally moving working roller 42 drives the dispersion rod 43 to push the catch to move laterally on the transport roller 25, so that the over-aggregated catch is dispersed and spread out on the transport roller 25 under the reciprocating force.

[0064] At the same time, dispersion columns 44 are evenly distributed at the bottom of the dispersion rod 43. During movement, the dispersion columns 44 can fit into the gaps between the entangled fish and pull the fish apart during movement, thereby further reducing the entanglement and aggregation of the fish. The spherical structure at the bottom of the dispersion columns 44 can also reduce damage to the contacting fish during the contact process, avoiding damage to the fish, resulting in poor quality, difficulty in sale, and loss.

[0065] By further dispersing the catch, the effective collection of catch information by the acquisition camera 11 is also guaranteed, which facilitates timely adoption of corresponding processing measures for the classified catch, improves the preservation rate of the catch, reduces the loss of catch transportation and storage, saves fishermen's energy and effectively improves fishing efficiency.

[0066] Example 4:

[0067] Based on the third embodiment, as shown in the accompanying drawings of the specification Figure 2-8 As shown, there are multiple implementation schemes for installing the collection camera 11 inside the working body 21. All of them can be applicable to the present application if they can effectively collect information about the catch. One possible implementation scheme is provided here. Specifically, on the inner wall of the working body 21 facing the first telescopic device 41, a plurality of information collection rollers 12 are evenly provided on the upper side of the transport roller 25. The information collection rollers 12 are parallel to the transport rollers 25, and collection cameras 11 are evenly provided on the surface of the information collection rollers 12 facing the transport rollers 25. The collection cameras 11 are electrically connected to the information analysis module and can transmit the collected information data to the information analysis module in a timely manner.

[0068] Specific workflow: Based on the specific workflow in Example 3, in order to better collect information about the catch on the transport roller 25, a collection roller is provided above the transport roller 25 at a position corresponding to each classification area 26. In this way, the collection camera 11 on the information collection roller 12 located in the first classification area 26 can effectively collect information about the entire catch entering the working body 21.

[0069] As for the subsequent collection camera 11 on the information collection roller 12, after the catches of different individual sizes are sorted into different classification areas 26, the catches on the transport roller 25 continue to decrease, and the collection camera 11 located above can, on the one hand, collect information about the catches more clearly and unhindered, and on the other hand, can also effectively collect the catches of different individual sizes in the corresponding classification area 26, and analyze the types and proportions thereof, and combine them with the information of the first overall catch. After unified output, it is convenient for the corresponding analysts to analyze these data, summarize the proportions of different types and individual sizes in the catches more accurately and intuitively, and make a more reasonable and accurate comprehensive assessment of fishery resources.

[0070] Embodiment 5:

[0071] Based on the fourth embodiment, as shown in the accompanying drawings of the specification Figure 2-8 As shown, the working roller 42 is a cylindrical structure with a hollow interior, and an opening is provided at one end of the working roller 42 near the information collection roller 12; the end of the information collection roller 12 extends into the interior of the working roller 42, and an observation port 421 is provided on the side wall of the working roller 42 facing the collection camera 11, and a protective block 422 is provided on the inner wall of the working roller 42 between the observation ports 421. The protective block 422 here can be a cleaning sponge wrapped with a cleaning cloth specially used for cleaning cameras;

[0072] Specific work flow: On the basis of the specific work flow in Example 4, in order to better protect the smooth shooting of the collection camera 11 inside the working body 21, the intelligent control terminal is used for unified adjustment. When a large amount of catch enters, it gathers and agitates on the transport roller 25. At this time, the inflowing seawater and various impurities and dirt splash everywhere and adhere to the surface of the collection camera 11, which may affect the shooting of the collection camera 11. Therefore, in the initial state, the telescopic length of the No. 1 telescopic device 41 is controlled so that the collection camera 11 enters the interior of the working roller 42 and is located in the gap between the observation ports 421. At this time, the protective block 422 is in close contact with the end lens of the collection camera 11, which can effectively block the splashing impurities and dirt and protect the collection camera 11. Subsequently, after the catch has completely entered and calmed down, the transport roller 25 is started, and the No. 1 telescopic device 41 is started at the same time, so that the working roller 42 moves.

[0073] During this process, when the collection camera 11 enters the observation port 421 and obtains the shooting conditions, the collection camera 11 is started in time to start shooting. At this time, the No. 1 telescopic device 41 and the transport roller 25 are stopped. After the capture on the transport roller 25 facing the collection camera 11 is photographed, the No. 1 telescopic device 41 and the transport roller 25 are started again, so that the capture on the transport roller 25 is dispersed and processed while moving forward. When the new capture reaches the position on the transport roller 25 facing the collection camera 11, the collection camera 11 enters the observation port 421 again, and the above process is repeated to complete the shooting.

[0074] The intelligent control terminal can control the starting frequency of components such as the collection camera 11, the No. 1 telescopic device 41 and the drive motor on the transport roller 25 to complete the above process. During the reciprocating movement, the protective block 422 can effectively wipe the lens part at the end of the collection camera 11 and clean impurities and dirt that may be attached to it, thereby protecting the normal operation of the collection camera 11 while more fully collecting the catch information and improving the classification efficiency.

[0075] Example 6:

[0076] Based on the fifth embodiment, as shown in the accompanying drawings of the specification Figure 2-8 As shown, an annular cleaning chamber 423 is provided inside the side wall of the working roller 42. The cleaning chamber 423 communicates with an external water supply device through a connecting pipe 424. The external water supply device protects the purified seawater pool and water pump. The connecting pipe 424 is located inside the working body 21 and adopts a telescopic hose structure to adapt to the situation where the working roller 42 reciprocates and keeps the seawater inside the cleaning chamber 423. Cleaning holes 425 are evenly distributed on the side wall of the cleaning chamber 423 and at the corresponding positions of the protective block 422.

[0077] The dispersion rod 43 is hollow inside to form a water storage chamber 431, which is in communication with the interior of the cleaning chamber 423. Cleaning nozzles 432 are evenly distributed at the bottom of the dispersion rod 43, located in the gap between the dispersion columns 44. The cleaning nozzles 432 are in communication with the water storage chamber 431 and are controlled by the intelligent control terminal.

[0078] Specific workflow: Based on the specific workflow in Example 5, during the movement of the catch, the water supply device is started, so that the water pump delivers clean seawater into the cleaning chamber 423. A portion of the seawater enters the interior of the protective block 422 through the cleaning hole 425 and is squeezed out during the contact and squeezing process between the protective block 422 and the acquisition camera 11, thereby flushing away impurities that may be attached to the surfaces of the protective block 422 and the acquisition camera 11. The acquisition camera 11 is specially designed to be able to operate in seawater, so that it can operate normally under the flushing of seawater.

[0079] Another part of the seawater enters the water storage chamber 431 and is flushed downward under the action of the activated cleaning nozzle 432. This can, on the one hand, spray the seawater on the moving catch to ensure the activity of the catch, and also lubricate the sliding of the catch on the transport roller 25 by the seawater, reducing damage to the catch; on the other hand, when the gaps between the dispersion columns 44 are mixed with individual smaller catches, the power of the corresponding cleaning nozzle 432 can be increased to spray out a water flow with a larger impact force, thereby effectively cleaning the catch mixed in the gaps between the dispersion columns 44 and ensuring the normal operation of the dispersion columns 44.

[0080] Embodiment seven:

[0081] Based on the sixth embodiment, as shown in the accompanying drawings of the specification Figure 2-9 As shown, a tray 27 is provided in the classification area 26 below the transport roller 25. The bottom of the tray 27 is connected to the end of a second telescopic device 271 installed at the bottom of the working body 21. The second telescopic device 271 can also be an automatic telescopic device such as an electric telescopic rod.

[0082] A dredging block 272 is provided on the upper surface of the tray 27, facing the gap between the transport rollers 25. Auxiliary cameras 13 are provided on both sides of the dredging block 272. The auxiliary cameras 13 are electrically connected to the information analysis module and are equipped with equipment capable of underwater photography, such as the acquisition camera 11. A discharge chute 273 is provided at the bottom of the tray 27, located in the gap between the dredging block 272. A flap 274 is rotatably provided in the middle of the discharge chute 273. The flap 274 utilizes a rigid filter structure. When the fish lands on the flap 274, the seawater in the fish remains, reducing the load on the flap 274.

[0083] Specific work flow: Based on the specific work flow in Example 6, when the cleaning nozzle 432 continuously sprays seawater and accumulates at the bottom of the classification area 26, water accumulation is formed, which facilitates the normal survival of the catch that falls into it; in actual operation, considering that the depth of the accumulated water has reached a sufficient height and the individual catches are large, the catches that fall through the gap between the transport rollers 25 and fall into the classification area 26 may be damaged; therefore, the second telescopic device 271 is started to drive the tray 27 to move below the gap between the transport rollers 25. At this time, the fallen catches temporarily fall on the tray 27. When a large amount of catches accumulate on the tray 27, the second telescopic device 271 is started again to move the tray 27 downward and close to the bottom of the classification area 26. At this time, the tray 27 may enter the accumulated water; the motor on the flap 274 at the bottom of the tray 27 is controlled to rotate the flap 274, so that the catches are separated from the tray 27 and fall directly into the classification area 26, thereby reducing the damage to the falling catches in the process;

[0084] Furthermore, when the catch continues to clog the gap between the transport rollers 25, the second telescopic device 271 is started to move the tray 27 upward continuously until the end of the dredging block 272 on the tray 27 passes through the gap between the transport rollers 25, so that the catch therein is pushed out, thereby ensuring the smooth flow of the gap between the transport rollers 25; when the catch falls onto the tray 27, the auxiliary cameras 13 located on the two side surfaces of the dredging block 272 can take images of the catch on the tray 27 nearby and transmit the data to the information analysis module. Through the function of the auxiliary camera 13, the information analysis module can obtain the data of catches of different individual sizes entering different classification areas 26 by analyzing the data therein, and then comprehensively compare it with the data of the acquisition camera 11, which can effectively verify the data, appropriately reduce the acquisition error, improve the accuracy of the information finally obtained, and improve the efficiency of classifying the catch.

[0085] Embodiment 8:

[0086] Based on the above embodiments 1 to 7, as shown in the accompanying drawings Figure 1-9 As shown, a method for automatically collecting and classifying catch information is provided. The method uses the above-mentioned automatic collection and classification device for catch information, and the specific steps of the classification method are as follows:

[0087] S1: The automatic catch information collection and classification device is installed on a sailing fishing boat. During the fishing process, after the catch is caught in the fishing net, the fishing net is dragged by the winch 231, thereby pulling the fishing net toward the feed port 23 until the catch is dropped into the feed port 23; after the catch enters the working body 21, it falls onto the transport roller 25;

[0088] S2: The intelligent control terminal starts the motor connected to the transport roller 25, causing the transport roller 25 to rotate. The accumulated catches are moved under the driving action of the transport roller 25. During this process, the accumulated catches on the transport roller 25 are dispersed and spread out by the friction and vibration of the transport roller 25. The catches move slowly along with the slowly rotating transport roller 25.

[0089] S3: The acquisition camera 11 inside the working body 21 can more comprehensively capture the scattered fish catches and transmit the information to the information analysis module. By capturing the fish catches, the characteristics of different types of fish catches, such as color and shape, can be effectively identified. The information analysis module compares the different types of fish catches stored in advance to analyze the specific type and the proportion of the type in the number of fish catches in the image data, and transmits the data to the information management unit.

[0090] S4: The information management unit transmits the catch information to different fishery-related people, and makes corresponding preparations according to the type and quantity of the catch. Fishermen on the fishing boat can use collection boxes 3 with different type labels to collect the catch according to the currently displayed number of catches, thereby facilitating subsequent further screening and processing.

[0091] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
