Description

Technical Field

[0001] The invention relates to the technical field of campus card technology, and in particular to a campus card reading device. Background Art

[0002] The campus card reader is a device specifically used to read, process and manage campus card information. The campus card is usually a multifunctional smart card that students and faculty can use for a variety of campus activities, such as consumption, borrowing books, access control, attendance, etc. The main functions of the card reader are: Identity authentication: Verify the identity of the cardholder by reading the information on the campus card. Payment function: You can make consumption payments in campus cafeterias, supermarkets, print shops and other places. Borrowing books and borrowing items: Borrow books or other items in the library through card reading devices. Access control management: Cooperate with the access control system to ensure that only authorized personnel can enter specific areas. Attendance records: Teachers or schools can use readers to record student attendance. Campus card readers are usually installed in fixed locations such as cafeterias, supermarkets, and libraries for consumption or borrowing books. Readers mostly use RFID technology to read the chip information in the card contactlessly, thereby realizing the function of rapid identification and data processing.

[0003] The installation of the existing campus card reader is relatively troublesome, especially in the canteen and other usage scenarios. The campus card reader needs to be installed on the glass window and fixed by gluing. The fixing effect is not good and it is easy to cause safety hazards. If it is fixed by punching or other methods, it is inconvenient for later maintenance and repair work. Due to the large amount of oil in the canteen, after a long period of use, there will be oil on the surface of the campus card reader, which will reduce the comfort of students and teachers, and the experience cannot be guaranteed. It will also affect the normal operation of internal electronic components.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a campus card reading device to solve the above technical problems. Summary of the invention

[0005] The technical purpose to be achieved by the present invention is to design a campus card reader device, to provide an exclusive base for the existing campus card reader device, to facilitate the inspection and maintenance of the campus card reader device, to increase the mobility of the campus card reader device and to enhance the heat dissipation performance of the campus card reader device.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] The campus card reader device includes a base plate mechanism, an installation mechanism, a reinforcement mechanism and a fixing mechanism. The four parts together constitute a stable and efficient installation system to ensure the firmness of the reading device and the normal operation of its functions.

[0008] The glass curtain wall is arranged at the windows of the campus canteen, student office and library; the card body is installed in the bottom plate mechanism.

[0009] The base plate mechanism is the basic part of the whole device, which is installed on the glass window. Since many campus card readers need to be installed facing the glass windows in public areas, this design provides a more flexible installation method. The base plate mechanism not only provides a stable support, but also has a certain degree of mobility, and can move or adjust the angle of the device according to needs in specific situations. This flexible design ensures that the device can adapt to different environments, whether indoors or outdoors, the base plate mechanism can provide reliable support.

[0010] The mounting mechanism is mainly installed on the outer side of the base plate mechanism. Its core function is to position and limit the card reader during the installation process. Positioning is to ensure that the reader can be accurately placed in the predetermined position to avoid offset or error during the installation process; limiting is to limit the movement or shaking of the device during use to ensure that the reader remains stable during frequent use. This design is crucial to the long-term service life and precise operation of the device, especially in high-traffic areas such as campus entrances, cafeterias or libraries, where the card reader needs to withstand a large number of card swiping operations.

[0011] The reinforcement mechanism is installed in the middle part of the bottom plate mechanism to enhance the installation stability between the bottom plate and the glass window. It ensures that it will not loosen or break during daily use. In addition, the reinforcement mechanism can effectively improve the impact resistance and prevent the reading device from falling off due to external interference (such as vibration or impact).

[0012] The fixing mechanism is located on the inner side of the bottom plate mechanism, and its function is to firmly fix the bottom plate mechanism on the glass window. The fixing mechanism forms a stable connection between the bottom plate mechanism and the glass window. This strong fixing method can not only ensure the stability of the reading device during use, but also facilitate disassembly and reinstallation during maintenance.

[0013] The base plate mechanism is composed of a base plate body, ventilation slots, heat sinks, rotation slots and reinforcement holes. Each part cooperates with each other to ensure the stability and functionality of the equipment. The base plate body is installed on the glass window as a supporting structure for the entire device. Ventilation slots are opened on both sides of the base plate body to ensure air circulation and prevent the equipment from overheating. In order to further enhance the heat dissipation effect, the heat sink is installed inside the ventilation slot and is set in an oblique manner to increase the heat dissipation area and efficiency. The rotation slot is located inside the ventilation slot to facilitate the adjustment and movement of the equipment in certain situations, while the reinforcement hole is opened in the center of the rotation slot to provide an additional fixing point to enhance the stability and impact resistance of the base plate structure. This design not only helps the heat dissipation of the equipment, but also ensures its safety and durability during use.

[0014] The installation mechanism is composed of side panels, limit slots and positioning blocks, which work together to ensure the stability and accuracy of the equipment during installation. First, the side panels are installed on the outer side of the base plate mechanism as a structural element for connection and support, providing a solid foundation for the installation of the equipment. The limit slots are opened on the inner side of the side panels, and their shape is designed to be trapezoidal to effectively limit the lateral movement of the equipment and avoid deviation or sliding during installation. The limit slots ensure that the equipment is fixed and adjusted within a specific range through their specific shape and position. The positioning blocks are installed on the lower side of the side panels in the form of a linear array, designed to be stepped, matching the limit slots, and playing the role of precise positioning of the equipment. This shape and arrangement of the positioning blocks ensure that the equipment can be quickly and accurately aligned during installation, and remain stable during use, and are not prone to displacement or loosening. This design improves the efficiency and accuracy of installation, while also enhancing the safety and durability of the equipment.

[0015] The reinforcement mechanism consists of a rotating disk, a rotating rod and a spiral rod, and is ingeniously designed to further enhance the stability and structural strength of the equipment. First, the rotating disk is installed in the rotating groove. As the core component of the entire reinforcement mechanism, it can be flexibly adjusted during the installation process to facilitate the alignment and fixation of the equipment. The design of the rotating disk can not only improve the flexibility of installation, but also reduce the displacement of the equipment caused by external vibration or pressure. The rotating rod is installed on the side of the rotating disk to play a supporting and connecting role. By cooperating with the rotating disk, it enables the equipment to be fine-tuned within a limited range, thereby improving the accuracy and firmness of the installation. The spiral rod is installed on the other side of the rotating disk and is fixed to the base plate structure through the reinforcement hole. The design of the spiral rod further improves the stability of the equipment through the spiral fastening method, ensuring that the entire installation system is not easy to loosen or shift during long-term use. This combined design of the reinforcement mechanism not only enhances the fixation of the equipment, but also makes maintenance and adjustment more convenient and quick.

[0016] The reinforcement mechanism also includes a buffer gasket, a reinforcement block and an anti-skid protrusion, which work together to further enhance the stability of the device and provide additional protection measures. The buffer gasket is installed on the outside of the spiral rod to play a role in shock absorption and buffering, and can effectively disperse external forces to prevent damage or excessive pressure when the spiral rod directly contacts the glass window. The gasket increases the elasticity of the structure through the design of soft materials, so that the device remains stable when encountering vibrations or external forces. The reinforcement block is installed at the top of the spiral rod and works with the buffer gasket. It is located on the inner and outer sides of the glass window respectively, providing a two-way reinforcement effect. The reinforcement block enhances the stability and firmness of the entire system by evenly distributing force. In order to further prevent the device from sliding during use, the anti-skid protrusion is designed on the inner side of the reinforcement block to prevent sliding and displacement by increasing friction. This series of designs ensures that the device can remain stable under high-frequency use and external interference, and extends the service life of the device while reducing damage to the glass.

[0017] The fixing mechanism is composed of a connecting component, a suction cup and a valve component, which ensures the stability and flexibility of the campus card reader during the installation process. The connecting component is installed on the rear side of the base plate mechanism, and serves as a connecting bridge between the device and the fixing device, providing a solid support. The suction cup is installed on the surface of the connecting component, and uses the vacuum adsorption principle to firmly fix the device. It is especially suitable for smooth surfaces such as glass windows and can provide strong adsorption force. The valve component is located inside the connecting component. By adjusting the airflow to make it flow in one direction, the adsorption force of the suction cup is controlled, making the equipment installation easier and faster, and also convenient for disassembly when needed. This design ensures the stability of the equipment and simplifies the installation and maintenance process.

[0018] The connecting assembly consists of a connecting sleeve, an air outlet and an air inlet, and is mainly used to control the airflow inside the device, thereby enhancing the fixing effect. The connecting sleeve is installed on the inner side of the base plate mechanism. As a key part of airflow conduction and connection, its design ensures the overall stability of the device. The air outlet is opened on the side of the connecting sleeve, and the air inlet is located at the bottom of the connecting sleeve. It is designed to be bottleneck-shaped, which plays a role in controlling the entry of airflow. Ensure the stability and safety of the suction cup during adsorption. This airflow control design makes the adsorption process of the equipment more efficient and improves the overall installation firmness and safety.

[0019] The suction cup is made of soft rubber with good elasticity and adaptability. It can fit tightly to various smooth surfaces and provide strong adsorption force. A number of auxiliary depressions are designed on the inner surface of the suction cup. These depressions not only increase the contact area between the suction cup and the surface, but also enhance the adsorption force. When in use, adding a small amount of pure water inside the auxiliary depression can further improve the sealing and adsorption effect of the suction cup, ensuring that it will not fall off easily during long-term use. A matching bevel is set at the bottom of the inner side of the suction cup. This design helps to disperse the pressure on the edge of the suction cup and prevent uneven adsorption. At the same time, it makes the suction cup smoother when adsorbing and loosening, reducing friction and damage to the surface. The overall design improves the practicality and durability of the suction cup.

[0020] The valve assembly consists of a fixed disc, a return spring, a telescopic sleeve, a switch head and a control hole, which is designed to control the adsorption and release of the suction cup, thereby ensuring the flexibility and stability of the equipment. The fixed disc is installed at the top of the inner part of the connection assembly, serving as the support base of the entire valve assembly to ensure the stability of its structure. Below it is a return spring, which can quickly return to its original shape after external force is applied, playing a role of buffering and regulation, ensuring the flexibility and reliability of the switch operation.

[0021] Further down, the telescopic sleeve is installed under the return spring, which has good elasticity and can adjust the opening and closing of the valve according to different working conditions. This design allows the equipment to quickly adapt to environmental changes during adsorption and release, maintaining good working efficiency. The switch head is installed under the telescopic sleeve, and the valve is switched on and off through simple mechanical actions to control the in and out of the airflow. The control hole is opened on the side of the switch head to provide a channel for airflow.

[0022] The cross-sectional shape of the switch head is designed to be a trapezoid with a unique geometric structure. The length of the smaller bottom side of this design is less than the minimum diameter of the air inlet, ensuring smooth passage of airflow and avoiding obstruction. This trapezoidal structure can effectively control the in and out of airflow, making the valve more flexible in operation, thereby improving the overall performance and work efficiency of the equipment and ensuring stability during use.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention designs an exclusive base for the existing campus card reader, which brings many benefits, especially in terms of maintenance and heat dissipation performance. The design of the exclusive base greatly facilitates the inspection and maintenance of the campus card reader. Due to the reasonable structure of the base, the disassembly and installation of the equipment becomes easier, and the technicians can quickly carry out inspections and necessary repairs without damaging the equipment, thereby reducing the downtime of the equipment due to failures and improving work efficiency. In addition, the design of the base also provides a clear operating guide, reduces the difficulty of maintenance, and ensures that any operator can quickly get started. The base enhances the heat dissipation performance of the campus card reader. Since the equipment may generate heat when it runs for a long time, the exclusive base adopts an optimized heat dissipation design, such as the reasonable layout of ventilation slots and heat dissipation plates, so that the heat can be quickly dissipated and the risk of overheating of the equipment is reduced. This heat dissipation measure not only extends the service life of the equipment, but also improves its working stability, ensuring that good performance can be maintained under high-frequency use.

[0025] 2. The fixing mechanism adopts a suction cup design to ensure that the device is stable during use. By allowing the gas in the suction cup to flow outward in one direction only, this design effectively ensures the durability of the adsorption force and prevents the suction cup from loosening or falling off due to external vibration or impact. This one-way airflow design can effectively improve the adsorption effect, allowing the device to always maintain good adhesion during use. The setting of the reinforcement mechanism further ensures the stability of the campus card reader during operation. Through a reasonable reinforcement structure, it can effectively resist external impacts and avoid displacement or damage to the equipment due to unexpected factors. This design that enhances stability improves the reliability of the campus card reader in practical applications and ensures that it can consistently complete the card reading operation in a high-flow, high-frequency use environment. The exclusive base established by the present invention not only improves the maintenance convenience and heat dissipation performance of the campus card reader, but also ensures the stability and reliability of the equipment through the fixing mechanism and the reinforcement mechanism, thereby improving the overall user experience.

DETAILED DESCRIPTION

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1-10As shown, the campus card reader includes a base plate mechanism 1, a mounting mechanism 2, a reinforcement mechanism 3 and a fixing mechanism 4, and the four parts together constitute a stable and efficient installation system to ensure the firmness of the reader and the normal operation of the function. The glass curtain wall 6 is set at the windows of the campus cafeteria, student office and library; the card body 5 is installed in the base plate mechanism 1.

[0041] The bottom plate mechanism 1 is the basic part of the whole device, which is installed on the glass window. Since many campus card readers need to be installed facing the glass windows in public areas, this design provides a more flexible installation method. The bottom plate mechanism 1 not only provides a stable support, but also has a certain degree of mobility, and can move or adjust the angle of the device according to needs in specific situations. This flexible design ensures that the device can adapt to different environments. Whether indoors or outdoors, the bottom plate mechanism 1 can provide reliable support.

[0042] The mounting mechanism 2 is mainly installed on the outer side of the base mechanism 1. Its core function is to position and limit the card reader during installation. Positioning is to ensure that the reader can be accurately placed in the predetermined position to avoid offset or error during installation; limiting is to limit the movement or shaking of the device during use to ensure that the reader remains stable during frequent use. This design is crucial to the long-term service life and precise operation of the device, especially in high-traffic areas such as campus entrances, cafeterias or libraries, where the card reader needs to withstand a large number of card swiping operations.

[0043] The reinforcement mechanism 3 is installed in the middle part of the bottom plate mechanism 1, and its function is to enhance the installation stability between the bottom plate and the glass window, ensuring that it will not become loose or damaged during daily use. In addition, the reinforcement mechanism 3 can also effectively improve the impact resistance and prevent the reading device from falling off due to external interference (such as vibration or impact).

[0044] The fixing mechanism 4 is located on the inner side of the bottom plate mechanism 1, and its function is to firmly fix the bottom plate mechanism 1 on the glass window. The fixing mechanism 4 forms a stable connection between the bottom plate mechanism 1 and the glass window. This strong fixing method can not only ensure the stability of the reading device during use, but also facilitate disassembly and reinstallation during maintenance.

[0045] like Figure 2As shown, the bottom plate mechanism 1 is composed of a bottom plate body 11, a ventilation slot 12, a heat sink 13, a rotation slot 14 and a reinforcement hole 15, and each part cooperates with each other to ensure the stability and functionality of the device. The bottom plate body 11 is installed on the glass window as a supporting structure for the entire device. The ventilation slots 12 are opened on both sides of the bottom plate body 11 to ensure air circulation and prevent the device from overheating. In order to further enhance the heat dissipation effect, the heat sink 13 is installed inside the ventilation slot 12 and is arranged in an oblique manner to increase the heat dissipation area and efficiency. The rotation slot 14 is located inside the ventilation slot 12 to facilitate the adjustment and movement of the device in certain situations, while the reinforcement hole 15 is opened in the center of the rotation slot 14 to provide an additional fixing point to enhance the stability and impact resistance of the bottom plate structure. This design not only helps the heat dissipation of the device, but also ensures its safety and durability during use.

[0046] like Figure 2-3 As shown, the installation mechanism 2 is composed of a side plate 21, a limiting groove 22 and a positioning block 23, which work together to ensure the stability and accuracy of the equipment during the installation process. First, the side plate 21 is installed on the outer side of the base plate mechanism 1 as a structural element for connection and support, providing a solid foundation for the installation of the equipment. The limiting groove 22 is opened on the inner side of the side plate 21, and its shape is designed to be trapezoidal to effectively limit the lateral movement of the equipment and avoid deviation or sliding during the installation process. The limiting groove 22 ensures that the equipment is fixed and adjusted within a specific range through its specific shape and position. The positioning block 23 is installed on the lower side of the side plate 21 in the form of a linear array, and is designed to be stepped, matching the limiting groove 22, and plays a role in accurately positioning the equipment. This shape and arrangement of the positioning block 23 ensure that the equipment can be quickly and accurately aligned during installation, and remain stable during use, and is not prone to displacement or loosening. This design improves the efficiency and accuracy of installation, while also enhancing the safety and durability of the equipment.

[0047] like Figure 4As shown, the reinforcement mechanism 3 is composed of a rotating disk 31, a rotating rod 32 and a spiral rod 33, and is exquisitely designed to further enhance the stability and structural strength of the equipment. First, the rotating disk 31 is installed in the rotating groove 14. As the core component of the entire reinforcement mechanism 3, it can be flexibly adjusted during the installation process to facilitate the alignment and fixation of the equipment. The design of the rotating disk 31 can not only improve the flexibility of installation, but also reduce the displacement of the equipment caused by external vibration or pressure. The rotating rod 32 is installed on the side of the rotating disk 31 to play a supporting and connecting role. It cooperates with the rotating disk 31 to enable the equipment to be fine-tuned within a limited range, thereby improving the accuracy and firmness of the installation. The spiral rod 33 is installed on the other side of the rotating disk 31 and is fixed to the bottom plate structure through the reinforcement hole 15. The design of the spiral rod 33 further improves the stability of the equipment through the spiral fastening method, ensuring that the entire installation system is not easy to loosen or shift during long-term use. This combined design of the reinforcement mechanism 3 not only enhances the fixity of the equipment, but also makes maintenance and adjustment more convenient and quick.

[0048] The reinforcement mechanism 3 also includes a buffer gasket 34, a reinforcement block 35 and an anti-skid protrusion 36, which work together to further enhance the stability of the device and provide additional protective measures. The buffer gasket 34 is installed on the outside of the spiral rod 33 to play a role in shock absorption and buffering, and can effectively disperse external forces to prevent the spiral rod 33 from directly contacting the glass window and causing damage or excessive pressure. The gasket increases the elasticity of the structure through the design of soft materials, so that the device remains stable when encountering vibrations or external forces. The reinforcement block 35 is installed at the top of the spiral rod 33 and works in conjunction with the buffer gasket 34. They are located on the inner and outer sides of the glass window, respectively, to provide a two-way reinforcement effect. The reinforcement block 35 enhances the stability and firmness of the entire system by evenly distributing force. In order to further prevent the device from sliding during use, the anti-skid protrusion 36 is designed on the inner side of the reinforcement block 35 to prevent sliding and displacement by increasing friction. This series of designs ensures that the device can remain stable under high-frequency use and external interference, and prolongs the service life of the device while reducing damage to the glass.

[0049] like Figure 5-6As shown, the fixing mechanism 4 is composed of a connecting component 41, a suction cup 42 and a valve component 43, which ensures the stability and flexibility of the campus card reader during the installation process. The connecting component 41 is installed on the rear side of the base plate mechanism 1, and serves as a connecting bridge between the device and the fixing device, providing a solid support. The suction cup 42 is installed on the surface of the connecting component 41, and uses the vacuum adsorption principle to firmly fix the device. It is particularly suitable for smooth surfaces such as glass windows and can provide a strong adsorption force. The valve component 43 is located inside the connecting component 41. By adjusting the airflow to make it flow in one direction, the adsorption force of the suction cup 42 is controlled, making the equipment installation easier and faster, and also convenient for disassembly when needed. This design ensures the stability of the equipment and simplifies the installation and maintenance process.

[0050] like Figure 7 As shown, the connecting component 41 is composed of a connecting sleeve 411, an air outlet 412 and an air inlet 413, which are mainly used to control the airflow inside the device, thereby enhancing the fixing effect. The connecting sleeve 411 is installed on the inner side of the base plate mechanism 1. As a key part of airflow conduction and connection, its design ensures the overall stability of the device. The air outlet 412 is opened on the side of the connecting sleeve 411, and the air inlet 413 is located at the bottom of the connecting sleeve 411. It is designed to be bottleneck-shaped, which plays a role in controlling the entry of airflow. Ensure the stability and safety of the suction cup 42 during the adsorption process. This airflow control design makes the adsorption process of the equipment more efficient and improves the overall installation firmness and safety.

[0051] The suction cup 42 is made of soft rubber, has good elasticity and adaptability, can fit tightly with various smooth surfaces, and provide strong adsorption force. A plurality of auxiliary depressions 421 are designed on the inner surface of the suction cup 42. These depressions not only increase the contact area between the suction cup 42 and the surface, but also enhance the adsorption force. When in use, adding a small amount of pure water inside the auxiliary depression 421 can further improve the sealing and adsorption effect of the suction cup 42, ensuring that it will not fall off easily during long-term use. A matching bevel 422 is provided at the bottom end of the inner side of the suction cup 42. This design helps to disperse the pressure on the edge of the suction cup 42 to prevent uneven adsorption, while making the suction cup 42 smoother during adsorption and loosening, reducing friction and damage to the surface. The overall design improves the practicality and durability of the suction cup 42.

[0052] like Figure 8As shown, the valve assembly 43 is composed of a fixed disc 431, a return spring 432, a telescopic sleeve 433, a switch head 434 and a control hole 435, which is intended to control the adsorption and release of the suction cup 42, thereby ensuring the flexibility and stability of the device. The fixed disc 431 is installed at the top of the inner part of the connecting assembly 41, serving as the supporting base of the entire valve assembly 43 to ensure the stability of its structure. Below it is the return spring 432, which can quickly return to its original shape after an external force is applied, playing a role of buffering and regulation, ensuring the flexibility and reliability of the switch operation.

[0053] Further downward, the telescopic sleeve 433 is installed below the return spring 432, and has good elasticity, which can adjust the opening and closing of the valve according to different working conditions. This design allows the device to quickly adapt to environmental changes during adsorption and release, and maintain good working efficiency. The switch head 434 is installed below the telescopic sleeve 433, and the switch of the valve is realized through simple mechanical actions to control the in and out of the airflow. The control hole 435 is opened on the side of the switch head 434, providing a channel for the airflow.

[0054] The cross-sectional shape of the switch head 434 is designed to be a trapezoid, with a unique geometric structure. The length of the smaller bottom side of this design is less than the minimum diameter of the air inlet, ensuring smooth passage of airflow and avoiding obstruction. This trapezoidal structure can effectively control the inflow and outflow of airflow, making the valve more flexible in operation, thereby improving the overall performance and work efficiency of the equipment and ensuring stability during use.

[0055] During the working process of the present invention, the staff punches a hole in the glass window, adds water to the auxiliary depression 421, and presses the four corners of the bottom plate mechanism 1 with the suction cup 42 in the fixing mechanism 4 against the glass window, so that the suction cup 42 is adsorbed on the glass window;

[0056] The staff presses the bottom plate body 11, and the suction cup 42 is deformed by force. The gas enters the interior of the connecting sleeve through the air inlet hole 413. The high air pressure causes the reset spring 432 to contract, so that the gas can enter the interior of the connecting sleeve 411 from both sides of the switch head 434 and the control hole 435, and be discharged from the air outlet 412. The suction cup 42 is flattened as much as possible, and the water in the auxiliary depression 421 helps to fill some gaps, thereby ensuring as much vacuum as possible, thereby achieving vacuum fixation, and the bottom plate mechanism 1 is fixed on the glass window;

[0057] The staff passes the spiral rod 33 through the reinforcement hole 15 and the hole drilled in advance on the glass window, places the buffer gasket 34 and the reinforcement block 35 on both sides of the glass window, rotates the rotating rod, and further fixes the base plate body 11 on the glass window, thereby achieving installation.

[0058] After the installation of the base plate mechanism 1 is completed, the campus card reader is installed between the installation mechanisms 2, and two fixing blocks with trapezoidal cross-sections are installed on the two sides of the existing campus card reader, and a stepped positioning hole identical to the positioning block 23 is opened at the bottom, so that the campus card reader is slidably installed from the top of the base plate mechanism 1, thereby realizing the positioning and limiting effect of the campus card reader and ensuring stability during use.

[0059] Various modifications to the present disclosure will be apparent to those of ordinary skill in the art, and the general principles defined herein may be applied to other variations without departing from the scope of the present disclosure. Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the widest scope consistent with the principles and novel features disclosed herein. Although one or more exemplary embodiments of the present disclosure have been described with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present disclosure as defined in the appended claims.
