DETAILED DESCRIPTION

[0057] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more such features, and are used to distinguish between the described features, without distinction of order or importance.

[0059] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0060] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0061] A key management machine, such as Figures 1 to 2 As shown, it includes a main box 1, a protective door 2, a key locking module 3, an emergency unlocking module 4, a door locking assembly 5, an emergency unlocking knob module 6 and a control system installed in the main box 1;

[0062] The protective door 2 is used to cover the front opening of the main box 1. The door locking assembly 5 is located in the main box 1. The door locking assembly 5 is electrically connected to the control system. After being authorized by the control system, the door locking assembly 5 is used to unlock and lock the protective door 2.

[0063] The emergency unlocking module 4 is installed in the main box 1 and includes a super key box 41. The super key box 41 is used to store the super key 01. The super key 01 is used to unlock the key locking module 3.

[0064] The emergency unlocking knob module 6 is mounted on the main housing 1 and is located on one side of the door lock assembly 5. Rotating the emergency unlocking knob module 6 triggers unlocking of the door lock assembly 5 and triggers the super key box 41 to pop out from the main housing 1. When the super key box 41 is in the pop-up position, it is used to prevent the protective door 2 from closing on the main housing 1.

[0065] The emergency unlocking module 4 is electrically connected to the control system, and the control system allows or prevents the resetting of the super key box 41 and is used to send a signal whether the super key 01 is in the super key box.

[0066] If a circuit or software failure occurs in an existing key management machine and a mechanical key must be used urgently, it is generally necessary to use special tools such as a safety hammer and pliers to destroy the door glass and the key column to remove the mechanical key. After the circuit or software failure is repaired, the key management machine needs to be disassembled and replaced with a new door glass and key column. This solution requires manpower, material resources, time, etc., and the maintenance cost is high. Therefore, the present invention proposes a key management machine, by arranging an emergency unlocking module 4 inside the main box 1 and an emergency unlocking knob module 6 outside the main box 1. When a circuit or software failure occurs and a mechanical key must be used urgently, the door lock assembly 5 can be unlocked by turning the knob of the emergency unlocking knob module 6 to open the protective door 2, and at the same time, the super key box 41 is unlocked and pops out from the main box 1. The super key box 41 is used to store the super key. The super key 01 is taken out to unlock the key lock module 3. After the super key box 41 pops out from the main box 1, the emergency unlocking module 4 can block the protective door 2 from covering the main box 1. Therefore, the protective door 2 cannot be closed before the super key box 41 is reset. The emergency unlocking module 4 is electrically connected to the control system. The control system controls the resetting of the super key box 41. The reset of the super key box 41 after it pops out requires the key management machine to be powered on and authorized by the control system. Therefore, in the event of a circuit or software failure, obvious traces of the use of the super key will be left. Or during the normal use of the key management machine, if the super key 01 is taken without authorization from the control system, the protective door 2 cannot be closed. At the same time, after the control system is powered on, it will receive and feedback whether the super key 01 is in the super key box 41. The key management personnel will receive a reminder that the super key 01 is not in place, which can effectively control the super key. Therefore, the emergency unlocking process of the key management machine will not cause any damage, and the key management machine can be easily restored after authorization, which greatly reduces the maintenance cost of emergency unlocking; at the same time, the control system of the key management machine can monitor the presence information of the super key 01. In a specific embodiment, if it is detected that the super key 01 is not in place, an alarm device will be triggered, such as a flashing alarm light and a buzzer alarm sound, etc. At the same time, the background pushes the information that the super key is not in place until the leader authorizes the restoration of the emergency unlocking module, which is convenient for the management and control of the super key.

[0067] In an alternative embodiment, if Figure 3 As shown, the protective door 2 is provided with a door hook 21;

[0068] The door locking assembly 5 includes a door control circuit board 51 and a door control electromagnet 52 , wherein the door control circuit board 51 and the door control electromagnet 52 are electrically connected, and the door control circuit board 51 is electrically connected to the control system;

[0069] When the iron core of the door control electromagnet 52 is in an extended state, the door hook 21 is locked to the main box 1; when the iron core of the door control electromagnet 52 is in an extended and retracted state, the door hook 21 is unlocked from the main box 1;

[0070] The emergency unlocking knob module 6 includes a knob 61 and a transmission assembly 62;

[0071] The knob 61 is mounted on the main housing 1 , the operating end of the knob 61 is located outside the main housing 1 , and the output end of the knob 61 is connected to a pusher 611 , which is located inside the main housing 1 ;

[0072] The transmission assembly 62 is elastically connected to the emergency unlocking module 4, one end of the transmission assembly 62 is fixedly connected to the iron core of the door control electromagnet 52, and the other end of the transmission assembly 62 is located below the pushing portion 611;

[0073] When the knob 61 is rotated, the rotation of the knob 61 drives the pushing portion 611 to rotate. When the rotation of the pushing portion 611 drives the transmission assembly 62 to move downward, the iron core of the door control electromagnet 52 moves downward to unlock the door hook 21, and the output end of the transmission assembly 62 causes the super key box 41 to pop out.

[0074] To further illustrate, when the protective door 2 is closed, the iron core of the gate-controlled electromagnet 52 limits the door hook 21 of the protective door 2, so that the door hook 21 is locked and the protective door 2 cannot be opened. The control system can authorize the iron core of the gate-controlled electromagnet 52 electrically connected to the door-controlled circuit board 51 to extend or retract to realize the opening and closing of the protective door 2. When the control system is powered off, the knob 61 can be rotated to drive the push part 611 to rotate. A transmission assembly 62 is provided below the push part 611, and one end of the transmission assembly 62 is fixedly connected to the iron core of the door control electromagnet 52. When the push part 611 pushes the transmission assembly 62 downward, it drives the iron core of the door control electromagnet 52 downward, causing the door hook 21 to be mechanically unlocked and the protective door 2 to open. At the same time, when the transmission assembly 62 moves downward, the output end of the transmission assembly 62 can eject the super key box 41. Therefore, when a circuit or software failure occurs and the mechanical key must be used urgently, the knob 61 can be rotated using any convenient tool such as a flat-blade screwdriver to both open the protective door 2 and eject the super key box 41 of the emergency unlocking module 4 to access the super key 01. When the knob 61 is turned to drive the push part 611 away from the transmission assembly 62, the transmission assembly 62 is elastically connected to the emergency unlocking module 4, and the transmission assembly 62 can be reset. The structure is simple, the operation is convenient, and no damage is caused.

[0075] In an alternative embodiment, if Figure 4 As shown, the emergency unlocking module 4 includes a fixing seat 42, a second elastic member 43, a limiting electromagnet 44, a limiting component 45 and a sensing component;

[0076] The fixing seat 42 is fixedly installed inside the main box 1, the super key box 41 is located inside the fixing seat 42, and the second elastic member 43 is provided between the super key box 41 and the fixing seat 42;

[0077] The super key box 41 is provided with the limiting assembly 45 , and the super key box 41 and the fixing seat 42 are connected via the limiting assembly 45 . The transmission assembly 62 is used to separate the limiting end of the limiting assembly 45 from the fixing seat 42 .

[0078] A limiting groove 411 is provided at the bottom of the rear end of the super key box 41. The limiting electromagnet 44 is provided below the front end of the fixing seat 42. A second through hole 421 is provided at the bottom of the front end of the fixing seat 42. The driving end of the limiting electromagnet 44 is passed through the second through hole 421 and abuts against the lower end surface of the super key box 41. When the super key box 41 pops out until the iron core of the limiting electromagnet 44 is located in the limiting groove 411, the super key 01 can be removed from the super key box 41.

[0079] The limit electromagnet 44 and the sensing component are electrically connected to the control system respectively. The sensing component is used to detect whether the super key 01 is in the fixing seat 42.

[0080] Specifically, when the emergency unlocking knob module 6 is pressed, the limiting end of the limiting component 45 is separated from the fixing seat 42, and the super key box 41 is ejected forward by the second elastic member 43. When the iron core of the limiting electromagnet 44 is located in the limiting groove 411, the super key 01 can be taken out of the super key box 41. The limiting electromagnet 44 and the sensing component are electrically connected to the control system respectively. When the super key box 41 is located in the fixing seat 42, the top of the iron core of the limiting electromagnet 44 is passed through the second through hole 421 and abuts against the bottom of the super key box 41. When the limiting groove 411 and the second through hole 421 are opposite to each other up and down, the iron core of the electromagnet is fully extended to the In the limit slot 411, after using the super key 01, authorization is required to reset the limit electromagnet 44, otherwise the iron core of the limit electromagnet 44 will press against the limit slot 411 and the super key box 41 cannot be closed, resulting in the protective door 2 being unable to close. In addition, the sensing component is electrically connected to the control system. The sensing component is used to detect whether the super key 01 is in the fixing seat 42. In a specific embodiment, when the circuit or software fault is repaired, the sensing component detects that the super key is not in the fixing seat 42 and feeds back to the control system, causing the key management machine to flash the alarm light and sound the buzzer alarm. At the same time, the background pushes the information that the super key is not in place until the leader authorizes the restoration of the emergency unlocking module, so that the use of the super key is easy to control.

[0081] In a specific embodiment, the sensing component includes an in-position detection circuit board and a magnet 011;

[0082] The in-place detection circuit board is installed inside the fixing seat 42. The in-place detection circuit board is provided with a magnetoresistive sensor. The in-place detection circuit board is electrically connected to the control system. The magnet 011 is provided at one end of the super key 01. The magnetoresistive sensor senses the magnet 011 to detect whether the super key 01 is in the fixing seat 42. The structure is simple.

[0083] In an alternative embodiment, if Figure 4 As shown, the transmission assembly 62 includes a transmission plate 621, a first elastic member 622 and a push rod 623;

[0084] The transmission plate 621 is horizontally arranged and located above the fixing seat 42. The transmission plate 621 and the fixing seat 42 are elastically connected via the first elastic member 622. One end of the upper plate surface of the transmission plate 621 is fixedly connected to the bottom of the iron core of the door control electromagnet 52, and the other end faces the pushing portion 611. The push rod 623 is provided on the lower plate surface of the transmission plate 621. When the first elastic member 622 is in the reset state, the iron core of the door control electromagnet 52 is limitedly connected to the door hook 21.

[0085] The limiting assembly 45 includes a limiting pin 451 and a third elastic member 452; the third elastic member 452 is fixedly connected to the super key box 41, and the movable end of the third elastic member 452 is connected to the limiting pin 451. The fixing seat 42 is provided with a third through hole 422. When the third elastic member 452 is in a reset state, the limiting end of the limiting pin 451 passes through the super key box 41 and is located in the third through hole 422. The limiting end of the limiting pin 451 is arranged opposite to the push rod 623 in the upper and lower directions.

[0086] It is further explained that the transmission plate 621 is elastically connected to the top of the fixing seat 42 through the first elastic member 622. When the first elastic member 622 is in the reset state, the iron core of the gate control electromagnet 52 is limitedly connected to the door hook 21, and the limiting end of the limiting pin 451 passes through the super key box 41 and is located in the third through hole 422 to connect the super key box 41 to the fixing seat 42. When the pushing part 611 pushes the transmission plate 621 to move downward, the transmission plate 621 drives the iron core of the gate control electromagnet 52 to move downward to unlock the door hook 21. At the same time, the push rod 623 located on the lower plate surface of the transmission plate 621 moves downward to push the limiting end of the limiting pin 451 located in the third through hole 422 of the fixing seat 42 to move downward, so that after detaching from the fixing seat 42, the super key box 41 pops out. It has a simple structure and is easy to operate.

[0087] In a specific embodiment, two limiting sliding grooves 423 are provided at the upper end of the fixing seat 42, and the first elastic member 622 and the push rod 623 are respectively arranged to move up and down in the limiting sliding grooves 423, and the upper and lower movements of the first elastic member 622 and the push rod 623 are activated to limit and guide, so that during emergency unlocking, the operations of unlocking the door hook 21 and popping out the super key box are more precise.

[0088] In an alternative embodiment, if Figures 6 and 7 As shown, the key locking modules 3 are provided in a plurality, and the plurality of key locking modules 3 are vertically arranged in an array inside the main box 1 , and each of the key locking modules 3 is provided with a plurality of key columns 32 ;

[0089] The key locking module 3 includes a locking seat 31, a key column 32, a lock core 33, an emergency unlocking transmission mechanism 34 and a limiting element 35. A plurality of key columns 32 are inserted into the front side of the locking seat 31, the lock core 33 is mounted on the locking seat 31, and the emergency unlocking transmission mechanism 34 and the limiting element 35 are both mounted on the rear side of the locking seat 31.

[0090] The limiting elements 35 are electrically connected to the control system. The number of the limiting elements 35 is the same as the number of the key columns 32. Several limiting elements 35 are respectively used to lock or unlock the corresponding key columns 32.

[0091] The output end of the lock core 33 is in transmission connection with the emergency unlocking transmission mechanism 34 . The lock core 33 matches the super key 01 . The output end of the emergency unlocking transmission mechanism 34 is connected to the driving ends of the plurality of limiting elements 35 .

[0092] When the lock core 33 is rotated by rotating the super key 01, the rotation of the lock core 33 drives the emergency unlocking transmission mechanism 34 to move, and the movement of the emergency unlocking transmission mechanism 34 drives the driving ends of several of the limiting elements 35 to move. The movement of the driving ends of several of the limiting elements 35 causes several of the key columns 32 to be unlocked or locked on the locking seat 31.

[0093] To further illustrate, several key columns 32 are inserted into the locking seat 31, and a lock core 33 is installed on the locking seat 31. The output end of the lock core 33 is connected to the emergency unlocking transmission mechanism 34 located on the rear side of the locking seat 31, and the output end of the emergency unlocking transmission mechanism 34 is connected to the driving ends of several limiting elements 35. After several limiting elements 35 respectively lock the corresponding key columns 32, when there is a circuit or software failure, the super key 01 can be used to cooperate with the lock core 33 to rotate the lock core 33 to move the emergency unlocking transmission mechanism 34 downward. Since the output end of the emergency unlocking transmission mechanism 34 is connected to the driving ends of several limiting elements 35, the downward movement of the emergency unlocking transmission mechanism 34 can drive the driving ends of several limiting elements 35 to move downward, so that the key column 32 is unlocked, thereby realizing that several key columns 32 can be unlocked at one time using the super key 01, thereby improving the efficiency of emergency unlocking.

[0094] In an alternative embodiment, if Figure 8 As shown, the limiting element 35 includes an iron core 351 and a solenoid 352 , and the solenoid 352 is electrically connected to the control system;

[0095] The front side of the locking seat 31 is provided with a plurality of insertion holes 311, into which a plurality of key columns 32 can be respectively inserted. The bottom of the key column 32 is provided with a first groove 321, and the insertion hole 311 is provided with a first through hole 3111 corresponding to the first groove 321;

[0096] When the key column 32 is located in the insertion hole 311 , the iron core 351 can extend into or exit the first groove 321 through the first through hole 3111 ;

[0097] The key column 32 is provided with a second groove 322, and the second groove 322 and the first groove 321 are arranged on two opposite sides of the key column 32. A slot 3112 is provided in the socket 311, which is directly opposite to the second groove 322. A positioning marble 3113 and a first elastic member 3114 are provided in the slot 3112. The top end of the positioning marble 3113 is elastically connected to the first elastic member 3114. When the first elastic member 3114 is in the reset state, the arc end of the positioning marble 3113 passes through the slot 3112 and is located in the socket 311.

[0098] It is worth noting that when the key column 32 is inserted into the socket 311 of the locking seat 31, the control system controls the solenoid 352 to enable the iron core 351 to extend into or withdraw from the first groove 32 of the key column 32 through the first through hole 3111, or drives the iron core 351 through the emergency unlocking transmission mechanism 34, so that the limiting element 35 can lock or unlock the key column 32 in the socket 311; further, a second groove 322 is provided on the side opposite to the first groove 321 of the key column 32, and a slot hole is provided in the socket 311 that is directly opposite to the second groove 322. 3112, a positioning marble 3113 connected by a first elastic member 3114 is provided in the slot 3112, and the bottom end of the positioning marble 3113 passes through the slot 3112 through the elastic element 3144 and is located in the insertion hole 311. When the key column 32 is inserted into the insertion hole 311, it can be judged whether the key column 32 is inserted into place by whether the arc end of the positioning marble 3113 enters the second groove 322 of the key column 32. After being inserted into place, the operable iron core 351 can be extended into the first groove 321 to lock the key column 32, thereby improving the convenience of the locking operation of the key column 32.

[0099] In a specific embodiment, the second groove 322 and the first groove 321 are symmetrically arranged on opposite sides of the key column 32, and the second groove 322 can correspond to the first through hole 3111. The iron core 351 extends into or exits the second groove 322 through the first through hole 3111, so that the key column 32 can achieve a locking function when inserted from the front or back, thereby improving convenience of use.

[0100] Furthermore, a circuit board 36 is mounted on the rear side of the locking base 31. This circuit board 36 is electrically connected to the control system. A magnet and an identification component are located within the key column 32. The magnet cooperates with the magnetoresistive sensor on the circuit board 36 to detect position, while the identification component cooperates with the code reading inductor on the circuit board 36 to detect identity. This is prior art and will not be described in detail here. Due to the positioning of a positioning ball 3113 within the socket, the key column 32 will not move outward within the socket 311 in the absence of external force, allowing the circuit board 36 to accurately read information from the key column 32.

[0101] In an alternative embodiment, if Figure 9 As shown, the iron core 351 is provided with a boss 3511, and the boss 3511 is fixedly connected to the outer periphery of the iron core 351;

[0102] The emergency unlocking transmission mechanism 34 includes a movable frame 341 and a movable plate 342. The movable frame 341 is vertically arranged and is provided with a strip hole 3410. The strip hole 3410 is horizontally arranged. The movable plate 342 is fixedly connected to the bottom of the movable frame 341. The output end of the lock core 33 is provided with an eccentric shaft 331. The eccentric shaft 331 is passed through the strip hole 3410. The lower end surface of the movable plate 342 is in contact with the upper end surface of the boss 3511. When the eccentric shaft 331 is rotated by rotating the lock core 33, the rotation of the eccentric shaft 331 drives the movable plate 342 to push the boss 3511 to move upward or downward.

[0103] Specifically, the lock core 33 is rotated by the super key 01, and an eccentric shaft 331 is provided at the output end of the lock core 33. The eccentric shaft 331 passes through the horizontally arranged bar hole 3410 on the movable frame 341, and a movable plate 342 is installed at the lower end of the movable frame 341. The lower end surface of the movable plate 342 is in contact with the upper end surface of the boss 3511. When the limiting element 35 and the key column 32 are locked and connected, the lock core 33 is rotated by the super key 01, and the eccentric shaft 331 rotates to push the bar hole 3410, thereby driving the movable frame 341 to move downward, and the movable plate 342 follows the movable frame 341 to move downward, thereby pushing the several bosses 3511 on the iron core 351 to move downward at the same time, so that the key column 32 is unlocked. The structure is simple and the operation is convenient and quick.

[0104] In an alternative embodiment, if Figure 9As shown, the locking seat 31 is provided with a total of six insertion holes 311, and the six insertion holes 311 are arranged horizontally. Three insertion holes 311 are respectively provided on both sides of the lock core 33 and are located on the upper side of the insertion holes 311. The movable frame 341 is a Japanese-shaped structure, and the Japanese-shaped structure includes a first support rod 3411 located in the middle, second support rods 3412 located on the left and right sides, a first connecting rod 3413 located at the top and a second connecting rod 3414 located at the bottom. The strip hole 3410 is opened in the first connecting rod 3413, and the two insertion holes 311 located in the middle are respectively located between the two second support rods 3412 and the first support rod 3411. The six first limiting elements are horizontally arranged below the six insertion holes 311. The movable plate 342 is horizontally connected to the second connecting rod 3414 and is located between the six insertion holes 311 and the six bosses 3511.

[0105] Further explanation, a total of 6 horizontally arranged jacks 311 are provided on the locking seat 31, and a total of 6 key columns 32 are provided on the key locking module 3. The lock core 33 is located above the middle of the 6 jacks 311. The eccentric shaft 331 of the lock core 33 passes through the strip-shaped hole 3410 on the first connecting rod 3413. The first connecting rod 3413 is located above the jacks 311, and the first support rod 3411 is located in the middle of the six jacks 311. The two jacks 311 located in the middle are connected. 11 are respectively located between the two second support rods 3412 and the first support rod 3411, the movable plate 342 is horizontally connected to the second connecting rod 3414, and is located between the six jacks 311 and the six bosses 3511, so that the emergency unlocking transmission mechanism 34 does not occupy additional installation space when installed on the key locking module 3, so that the installation of the circuit board 36 on the locking seat 31 is not affected, and the structure is stable, ensuring that the super key 01 can unlock the 6 key columns on the locking seat 31 at a time.

[0106] Preferably, a limiting guide 37 is provided on the left and right sides of the second support rod 3412 respectively, and the limiting guide 37 is fixedly connected to the outer wall of the socket 311. The limiting surface of the limiting guide 37 faces the second support rod 3412 and fits with the side of the second support rod 3412.

[0107] It can be understood that the second support rod 3412 is located between the two insertion holes 311, and the limiting guide members 37 are respectively installed on the opposite outer wall surfaces of the two insertion holes 311, so that the two second support rods 3412 are both located between the two limiting guide members 37, and the limiting surface of the limiting guide member 37 faces the second support rod 3412 and fits with the side surface of the second support rod 3412. When the eccentric shaft 331 of the lock core 33 pushes the movable frame 341 in the strip hole 3410, the two second support rods 3412 of the movable frame 341 slide up and down along the two limiting surfaces respectively, playing the role of limiting guide, so that the movable frame 341 can move stably up and down, the structure is stable, and the mechanical unlocking of the key column 32 is accurate and stable.

[0108] A control method for a key management machine, applied to the key management machine as described above, comprises the following steps:

[0109] When receiving the unlocking signal sent by the background, the door locking component 5 is controlled to perform the unlocking action;

[0110] Real-time detection of whether the super key 01 is in the super key box 41. When the super key is not in the super key box 41, the alarm device is triggered and a message indicating that the super key is not in place is sent to the backend.

[0111] The authorization recovery instruction fed back by the background is received, and the emergency unlocking module 4 is controlled to release the reset block of the super key box 41 .

[0112] It should be noted that the above-mentioned control method is deployed in the control system of the key management machine. With the authorization of the control system, the iron core of the door control electromagnet 52 of the door locking assembly 5 is disengaged from the door hook 21 of the protective door 2, so that the protective door 2 is unlocked from the main box 1.

[0113] Specifically, a method for using a key management machine includes the following steps:

[0114] (1) Use any convenient tool such as a flat-blade screwdriver to turn the knob 61 and simultaneously move the transmission plate 621 downward, so that the door control electromagnet 52 is reset. At this time, the protective door 2 can be opened and the limit pin 451 is separated from the fixing seat 42;

[0115] (2) After the protective door 2 is opened, the super key box 41 pops out under the action of the second elastic member 43. At this time, the magnetic resistance sensor on the in-position detection circuit board recognizes that the super key 01 is not in place;

[0116] (3) When the super key box 41 is pulled outward, the iron core of the limit electromagnet 44 will be fully extended into the limit slot 411 of the super key box 41;

[0117] (4) After the super key box 41 is pulled into place, the super key 01 can be removed.

[0118] (5) Insert the super key 01 into the lock cylinder 33 on the key locking module 3 and rotate the lock cylinder 33 with the super key 01 to unlock the key column 32 on the key locking module 3;

[0119] (6) After using the super key, authorization is required to reset the limit electromagnet 44. Otherwise, the limit electromagnet 44 will press against the limit slot 411 and cannot close the super key box 41, causing the protective door 2 to be unable to close. In the event of a circuit or software failure, there will be obvious signs that the super key has been used.

[0120] (7) When the circuit or software fault is repaired, the key management machine will flash the alarm light and sound the buzzer alarm, and at the same time push the information that the super key is not in place until the key management personnel authorizes the restoration of the emergency unlocking module 4.

[0121] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily conceive of other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
