[0013] In addition, it is required to understand this application not only through the actual terms used, but also through the meaning implied by each term.

[0014] The following will describe in detail the technical solutions provided by each embodiment of this application in conjunction with the accompanying drawings.

[0015] An embodiment of this application provides an electronic device. Referring to Figures 1 to 18 , the electronic device 1 provided by the embodiment of this application includes: a main body 100, a cover body 200, a decorative ring assembly 300, and a camera module 400. The cover body 200 covers the main body 100, the cover body 200 is provided with a first through hole 210, and the decorative ring assembly 300 is connected to the peripheral part of the first through hole 210. The decorative ring assembly 300 and the main body 100 enclose a receiving cavity 500, and the camera module 400 is disposed in the receiving cavity 500. The decorative ring assembly 300 is provided with a ventilation channel 310, and the receiving cavity 500 communicates with the outside of the electronic device 1 through the ventilation channel 310.

[0016] In this way, in the embodiment of this application, the receiving cavity 500 where the camera module 400 is located communicates with the outside of the electronic device 1 through the ventilation channel 310. Therefore, when the water vapor content in the gas in the receiving cavity 500 is relatively high, the water vapor in the gas in the receiving cavity 500 can be dissipated to the outside of the electronic device 1 through the ventilation channel 310, so that the receiving cavity 500 and the outside of the electronic device 1 are in a water vapor balance state, so as to prevent water vapor from condensing in the window area of the camera module 400, thereby preventing fogging.

[0017] Exemplarily, the electronic device 1 is a mobile phone or a tablet computer, etc. The camera module 400 includes components such as a lens and an image sensor. When the electronic device 1 is a mobile phone, the cover body 200 is the back cover of the mobile phone.

[0018] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7, in some embodiments, the decorative ring assembly 300 includes an inner decorative ring 320 and an outer decorative ring 330. The "outer" decorative ring and the "inner" decorative ring described herein mean that the "outer" decorative ring is exposed to the outer surface of the electronic device 1, and the "inner" decorative ring is sleeved inside the "outer" decorative ring relative to the "outer" decorative ring. The inner decorative ring 320 is connected to the peripheral portion of the first through hole 210. The outer decorative ring 330 is located on the side of the cover 200 facing away from the main body 100, and the outer decorative ring 330 is sleeved outside the inner decorative ring 320. The outer decorative ring 330 is provided with a through portion 331, and the inner decorative ring 320 is provided with a second through hole 321. A channel between the through portion 331 and the second through hole 321 forms a ventilation channel 310.

[0019] In this way, by forming the ventilation channel 310 between the through portion 331 of the outer decorative ring 330 and the second through hole 321 of the inner decorative ring 320, the length of the path of the ventilation channel between the accommodation cavity 500 where the camera module 400 is located and the outside of the electronic device 1 can be reduced. Thus, the water vapor in the accommodation cavity 500 can be discharged more smoothly to the outside of the electronic device 1, and further, the anti-fogging performance of the window area of the camera module 400 can be improved.

[0020] In some embodiments, the through portion 331 is a notch provided on the side of the outer decorative ring 330 facing the cover 200. The side wall of the notch forms a ventilation gap with the cover 200. Alternatively, in other embodiments, the through portion 331 is a through hole opened in the outer decorative ring 330. Since the through portion 331 is mainly used to connect the area where the camera module 400 is located to the outside, the shape and position of the through portion 331 can be flexibly set according to actual needs, which will not be listed one by one here.

[0021] Reference Figure 1 、 Figure 4 、 Figure 6 and Figure 7 , in some embodiments, the inner decorative ring 320 includes a first side wall 322 and a first side plate 323 that are connected. The first side wall 322 protrudes in a direction away from the main body 100 relative to the first side plate 323. The first side wall 322 sequentially passes through the first through hole 210 and the outer decorative ring 330. The first side plate 323 is connected to the side surface of the peripheral portion of the first through hole 210 facing the main body 100, and the second through hole 321 is provided in the first side wall 322.

[0022] Exemplarily, during the installation of the inner decorative ring 320 and the outer decorative ring 330, the inner decorative ring 320 can be first positioned inside the cover body 200 and at a position opposite to the first through hole 210 of the cover body 200. Further, the first side wall 322 of the inner decorative ring 320 can be passed through the first through hole 210, and the first side plate 323 can be oriented towards the side of the cover body 200 and be sealingly connected to the peripheral portion of the first through hole 210. For example, an adhesive layer is provided on the side of the first side plate 323 facing the cover body 200, and the first side plate 323 is sealingly connected to the peripheral portion of the first through hole 210 through the adhesive layer. In addition, the outer decorative ring 330 can be sleeved outside the first side wall 322.

[0023] In this way, since the outer decorative ring 330 is provided with a through portion 331, the outer decorative ring 330 is spaced apart from the first side wall 322 of the inner decorative ring 320, and the first side wall 322 of the inner decorative ring 320 is provided with a second through hole 321. Therefore, the second through hole 321 can communicate with the outside of the electronic device 1 through the spaced area between the outer decorative ring 330 and the inner decorative ring 320 and the through portion 331 of the outer decorative ring 330. Thus, the camera module 400 provided inside the inner decorative ring 320 can communicate with the outside of the electronic device 1 through the ventilation channel 310 between the second through hole 321 and the through portion 331.

[0024] Reference Figure 1 、 Figures 3 to 5 、 Figure 8 and Figure 9 In some embodiments, the main body 100 includes a frame body 110, a circuit board 120, and a first bracket 130 that are distributed in sequence. The first bracket 130 is provided with a third through hole 131. It should be noted that the main body 100 can also be referred to as the device main body. When the electronic device 1 is a mobile phone, the frame body 110 is the middle frame of the mobile phone, the circuit board 120 is the main board or the secondary board, the first bracket 130 is the circuit board bracket, and the circuit board bracket is also called the main board bracket. The first bracket 130 is connected to the circuit board 120.

[0025] The decorative ring assembly 300 further includes a second bracket 340 and a lens 350. The second bracket 340 is disposed on the side of the inner decorative ring 320 and the outer decorative ring 330 facing away from the main body 100, and the lens 350 is disposed on the side of the second bracket 340 facing away from the main body 100. The second bracket 340 is provided with a fourth through hole 341, and the fourth through hole 341 is opposite to the third through hole 131. The camera module 400 is sequentially passed through the third through hole 131 and the fourth through hole 341.

[0026] Exemplarily, the body portion of the camera module 400 passes through the third through hole 131. The light incident portion of the camera module 400 passes through the fourth through hole 341. The lens 350 covers the side of the second bracket 340 facing away from the main body 100. Exemplarily, when the electronic device 1 is a mobile phone, the second bracket 340 is a decorative bracket for supporting the lens 350. Exemplarily, the decorative bracket is made of a light-shielding material, and the lens 350 is made of a transparent material. During the photographing process of the camera module 400, external light can enter the camera module 400 through the lens 350.

[0027] In this way, the periphery of the camera module 400 is successively the hole wall of the third through hole 131 of the first bracket 130, the first side wall 322 of the inner decorative ring 320, and the outer decorative ring 330. Thus, the accommodation cavity 500 where the camera module 400 is located can communicate with the ventilation channel 310 between the second through hole 321 and the through portion 331 through the gap region between the first bracket 130 and the inner decorative ring 320, so that the water vapor in the accommodation cavity 500 can pass through the gap region between the first bracket 130 and the inner decorative ring 320, as well as the ventilation channel 310 between the second through hole 321 and the through portion 331, and dissipate to the external environment, thereby preventing the water vapor from condensing in the window area of the camera module 400, and thus preventing the fogging phenomenon.

[0028] Reference Figure 3 and Figure 4 In some embodiments, a dust-proof and breathable member 720 is clamped between the periphery of the fourth through hole 341 and the housing of the camera module 400. Exemplarily, the dust-proof and breathable member 720 is a sealing foam. In this way, the area where the camera module 400 is located can exchange gas with the external environment through the dust-proof and breathable member 720, the fifth through hole 132, the second through hole 321, and the through portion 331 of the outer decorative ring 330, so that the area where the camera module 400 is located is in a water vapor balance state with the external environment, thereby preventing the water vapor from condensing in the window area of the camera module 400, and thus preventing the fogging phenomenon.

[0029] Reference Figures 4 to 6 In some embodiments, the first bracket 130 includes a base portion 133 and a second side wall 134. The third through hole 131 is provided in the base portion 133, and the second side wall 134 is provided on the side of the base portion 133 facing away from the circuit board 120. The second side wall 134 surrounds the periphery of the third through hole 131, and the second side wall 134 is provided with a fifth through hole 132. The fifth through hole 132 is opposite to the second through hole 321.

[0030] The first side wall 322 is disposed outside the second side wall 134. The inner decorative ring 320 also includes a second side panel 324, which is connected to the first side wall 322 and extends from the first side wall 322 in a direction away from the first side panel 323 toward the axis of the inner decorative ring 320. The second side panel 324 is located on the side of the second side wall 134 facing away from the base 133. In other words, the second side panel 324 extends inward from the first side wall 322 in a direction away from the first side panel 323 toward the axis of the inner decorative ring 320, and the second side panel 324 is located on the side of the second side wall 134 facing away from the base 133. In some embodiments, the second side wall 134 also serves to support the inner decorative ring 320.

[0031] In this way, by opening a fifth through hole 132 on the second side wall 134 of the first bracket 130 and opposite to the second through hole 321 of the inner decorative ring 320, water vapor in the area where the camera module 400 is located can be discharged to the external environment more smoothly, thereby improving the anti-fogging performance of the window area of the camera module 400.

[0032] In some embodiments, a moisture-absorbing dust absorber 730 is provided on the side of the second bracket 340 facing away from the lens 350. The moisture-absorbing dust absorber 730 is circumferentially arranged around the fourth through hole 341. Thus, by providing the moisture-absorbing dust absorber 730 on the side of the second bracket 340 facing away from the lens 350, the moisture-absorbing dust absorber 730 can absorb moisture and dust in the area where the camera module 400 is located, thereby preventing moisture and dust from adversely affecting the camera module 400. It should be noted that in some embodiments, the electronic device 1 includes multiple camera modules 400. For example, each of the camera modules 400 is a rear-facing camera. One of the camera modules 400 is a main camera module, another is a wide-angle camera module, and another is a periscope camera module.

[0033] When there are multiple camera modules 400, the first bracket 130 is provided with multiple third through holes 131, and the second bracket 340 is provided with multiple fourth through holes 341. The fourth through holes 341 correspond one-to-one to the third through holes 131, and the camera modules 400 are passed through the third through holes 131 and the fourth through holes 341 one-to-one.

[0034] Correspondingly, the outer decorative ring 330 has multiple through-holes 331, and the first sidewall 322 has multiple second through-holes 321. Each camera module 400 exchanges air with the outside environment through its corresponding second through-holes 321 and through-holes 331. Furthermore, the inner wall of the area where each camera module 400 is located is equipped with a moisture and dust absorber 730.

[0035] Exemplarily, the moisture-absorbing dust-absorbing member 730 includes dust-absorbing adhesive 731 and a moisture-absorbing block 732. For example, the dust-absorbing adhesive 731 may be made of materials such as "electrostatic fiber material," "titanium dioxide," or "double-sided tape." The dust-absorbing adhesive 731 is used to absorb small particles in the area where the camera module 400 is located, thereby reducing the impact of these particles on the camera module 400.

[0036] For example, moisture-absorbing block 732 is made from materials such as "polyester fiber with added hydrophilic groups," "nano-silica," "graphene," "calcium chloride," "activated alumina / activated carbon," "composite gel material," and "super absorbent polymer (SAP)." Moisture-absorbing block 732 is placed on the surface of dust-absorbing adhesive 731, and the area of dust-absorbing adhesive 731 not covered by moisture-absorbing block 732 forms a dust-absorbing zone. The combination of moisture-absorbing block 732 and dust-absorbing adhesive 731 serves both to absorb dust and moisture.

[0037] refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 13 In some embodiments, the decorative ring assembly 300 further includes a heat conducting member 360. The heat conducting member 360 includes an outer ring portion 361 and an inner ring portion 362, which are connected to each other. The outer ring portion 361 is at least partially located on a side of the second bracket 340 facing away from the outer decorative ring 330. The lens 350 is covered on a side of the heat conducting member 360 facing away from the outer decorative ring 330. The inner ring portion 362 is located in the area enclosed by the second bracket 340, the outer ring portion 361, and the lens 350.

[0038] For example, the inner ring portion 362 is raised relative to the lens 350 along the thickness direction of the lens 350. This increases the contact area between the inner ring portion 362 and the area enclosed by the second bracket 340, the outer ring portion 361, and the lens 350, thereby better transferring heat from the area enclosed by the second bracket 340, the outer ring portion 361, and the lens 350 to the outside. This ensures that the temperature inside and outside the lens 350 are in equilibrium, preventing condensation.

[0039] Exemplarily, thermal conductor 360 is made of a metal material to effectively transfer heat. For example, thermal conductor 360 is made of stainless steel, which has a thermal conductivity of 16 watts per meter degree (W / (m·K)), while the thermal conductivity of air is 0.025 W / m·K. Thermal conductor 360 can quickly transfer heat from the inside of lens 350 to the outside.

[0040] refer to Figure 1 、 Figure 4 、 Figure 8 and Figure 12, in some embodiments, the second bracket 340 includes an outer peripheral portion 342, a recessed portion 343, and a protruding portion 344 that are sequentially connected. The recessed portion 343 is disposed on the outer periphery of the protruding portion 344, the outer peripheral portion 342 is disposed on the outer periphery of the recessed portion 343, the protruding portion 344 is disposed circumferentially around the fourth through hole 341, and the recessed portion 343 is recessed away from the lens 350 relative to the protruding portion 344.

[0041] In this way, by making the recessed portion 343 recess away from the lens 350 relative to the protruding portion 344, the visual depth of the bottom surface of the recessed portion 343 relative to the lens 350 can be increased.

[0042] In some embodiments, the side surface of the recessed portion 343 facing the lens 350 is an uneven texture surface. Exemplarily, the cross-sectional shape of the uneven texture surface is wavy. Of course, in other embodiments, the uneven texture surface can also be of other shapes, which will not be listed one by one here. In this way, when the side surface of the recessed portion 343 facing the lens 350 is an uneven texture surface, the reflected light of the uneven texture surface will present an "alternating light and dark" pattern, forming a "texture". Exemplarily, the main body of the second bracket 340 is made of plastic material, and a covering layer is formed on the surface of the second bracket 340 through processes such as electroplating. For example, the material of the covering layer is metal, alloy, or composite material.

[0043] Reference Figure 8 、 Figure 9 、 Figures 14 to 16 , in some embodiments, the second bracket 340 is provided with a sixth through hole 345. The decorative ring assembly 300 further includes a cover body 370. The cover body 370 is disposed at the sixth through hole 345. The electronic device 1 further includes a laser sensor 610, and the laser sensor 610 is located on the side of the cover body 370 away from the lens 350. The laser sensor 610 includes a laser 611 and a laser detector 612. The cover body 370 is provided with a first infrared transmission portion 371 and a second infrared transmission portion 372. The laser 611 is opposite to the first infrared transmission portion 371, and the laser detector 612 is opposite to the second infrared transmission portion 372.

[0044] In this way, the infrared light emitted by the laser 611 can pass through the first infrared transmission portion 371 and the lens 350 and be emitted. After the emitted infrared light is reflected by the object in front of the camera module 400, it passes through the lens 350 and the second infrared transmission portion 372 and is directed to the laser detector 612. Furthermore, the distance between the object and the camera module 400 can be determined based on the laser sensor 610, so that the camera module 400 can perform focusing based on the distance between the object and the camera module 400.

[0045] Reference Figure 14 、 Figure 17 and Figure 18, in some embodiments, the electronic device 1 further includes an infrared emitter 620. For example, the infrared emitter 620 is used to implement the infrared remote control function. The infrared emitter 620 is located on the side of the cover 370 away from the lens 350. The cover 370 is further provided with a third infrared transmission part 373, and the infrared emitter 620 is opposite to the third infrared transmission part 373. In this way, the infrared light emitted by the infrared emitter 620 can pass through the third infrared transmission part 373 and the lens 350 and be emitted.

[0046] Exemplarily, the main body of the cover 370 is made of a light-shielding material. The main body of the cover 370 is provided with three through holes. All three through holes are filled with infrared-transmitting materials. The regions where the infrared-transmitting materials are located in the three through holes respectively form a first infrared transmission part 371, a second infrared transmission part 372, and a third infrared transmission part 373.

[0047] In some embodiments, the electronic device 1 further includes a blocking cover 630, and the blocking cover 630 is located between the laser sensor 610 and the cover 370. A first blocking ring 631 is provided at a position of the blocking cover 630 opposite to the laser 611, and the light-emitting part of the laser 611 faces the inner region of the first blocking ring 631. A second blocking ring 632 is provided at a position of the blocking cover 630 opposite to the laser detector 612, and the light-incident part of the laser detector 612 faces the inner region of the second blocking ring 632. A blocking strip 633 is provided between the first blocking ring 631 and the second blocking ring 632, and the blocking strip 633 abuts against the part of the blocking cover 630 located between the first infrared transmission part 371 and the second infrared transmission part 372.

[0048] Exemplarily, the blocking cover 630 is made of silica gel. The blocking cover 630 is used to prevent the light emitted by the laser 611 from being reflected multiple times in the region where the cover 370 is located and then hitting the laser detector 612, thereby affecting the detection accuracy of the laser sensor 610.

[0049] Reference Figure 1 , in some embodiments, the electronic device 1 further includes a flexible circuit board 640. The laser sensor 610 and the infrared emitter 620 are provided on the flexible circuit board 640. The flexible circuit board 640 is electrically connected to the circuit board 120.

[0050] In some embodiments, the electronic device 1 further includes a waterproof and breathable member 710, and the waterproof and breathable member 710 is provided in the through hole 331, and / or the waterproof and breathable member 710 is provided in the second through hole 321. In this way, by providing the waterproof and breathable member 710 at the through hole 331 and / or the second through hole 321, it is possible to prevent liquid from entering the interior of the electronic device 1 through the through hole 331 or the second through hole 321.

[0051] Exemplarily, reference Figure 6, the inner decorative ring 320 is provided with a groove 325, the bottom surface of the groove 325 is a plane, and the second through hole 321 is provided at the bottom of the groove 325. In this way, the waterproof and breathable member 710 can be laid on the bottom of the groove 325 so that the waterproof and breathable member 710 covers the second through hole 321.

[0052] Exemplarily, the waterproof and breathable member 710 can be a waterproof and breathable film. A waterproof and breathable film is a composite material that can effectively block the penetration of liquid water and allow water vapor to pass through. Of course, the waterproof and breathable member 710 can also be other devices with waterproof and breathable properties, which will not be listed one by one here.

[0053] Reference Figure 3 and Figure 4 , in the embodiment of the present application, three regions in the electronic device 1 communicate with the outside through the second through hole 321, the waterproof and breathable member 710 and the through portion 331.

[0054] The area where the camera module 400 is located communicates with the outside through the dustproof and breathable member 720, the fifth through hole 132, the second through hole 321, the waterproof and breathable member 710 and the through portion 331. That is, the area where the camera module 400 is located communicates with the outside environment through the first path L1 and the air permeable channel 310 between the second through hole 321 and the through portion 331.

[0055] As Figure 2 shown, the inner area of the cover 200, that is, the space between the cover 200 and the first bracket 130, communicates with the outside through the inner decorative ring 320, the gap between the cover 200 and the first bracket 130, the second through hole 321, the waterproof and breathable member 710 and the through portion 331. That is, the inner area of the cover 200 communicates with the outside environment through the second path L2 and the air permeable channel 310 between the second through hole 321 and the through portion 331.

[0056] The electronic device 1 further includes a display module 140, the display module 140 is disposed on a side of the main body 100 away from the cover 200, and the display module 140 covers the main body 100.

[0057] As Figure 3 shown, the inner area of the display module 140, that is, the area between the display module 140 and the cover 200, communicates with the outside through the gap between the inside of the frame 110, the circuit board 120, the inner decorative ring 320 and the first bracket 130, and the second through hole 321, the waterproof and breathable member 710 and the through portion 331. That is, the inner area of the display module 140 communicates with the outside environment through the third path L3 and the air permeable channel 310 between the second through hole 321 and the through portion 331.

[0058] In this way, it is not only possible to prevent water vapor from condensing in the window area of the camera module 400, thus avoiding the fogging phenomenon, but also to prevent the electronic device 1, the cover body 200 and the display module 140 from bulging and deforming in high-altitude areas.

[0059] To enable those skilled in the art to better understand the solutions provided in the embodiments of the present application, the following provides more detailed examples for reference by those skilled in the art.

[0060] Referring to Figure 1 , the electronic device 1 includes a plurality of camera modules 400. For example, the electronic device 1 includes 3 camera modules 400. For the convenience of distinction, among the 3 camera modules 400 shown in Figure 1 , the camera module located on the left is called the first camera module, the camera module located in the middle is called the second camera module, and the camera module located on the right is called the third camera module.

[0061] Since the first camera module has a relatively large thickness, a seventh through hole can be provided in the area of the circuit board 120 opposite to the first camera module. The first camera module can pass through the seventh through hole of the circuit board 120, and the first camera module can be fixedly connected to the frame body 110. In this way, by providing the seventh through hole on the circuit board 120, it is possible to avoid the problem that due to the relatively small distance between the circuit board 120 and the second bracket 340 when the first camera module is fixed to the circuit board 120, the first camera module interferes with the second bracket 340.

[0062] Since the thicknesses of the second camera module and the third camera module are relatively thinner than that of the first camera module, the second camera module and the third camera module can be fixed on the circuit board 120.

[0063] The first bracket 130 (for example, the main board bracket) is correspondingly provided with 3 third through holes 131. The 3 third through holes 131 are in one-to-one correspondence with the respective camera modules 400, and then the first bracket 130 is fixed to the circuit board 120 (for example, the main board).

[0064] Referring to Figure 3 and Figure 4, the first side wall 322 of the inner decorative ring 320 is inserted into the first through hole 210, and the first side plate 323 of the inner decorative ring 320 faces the side of the cover body 200 and is hermetically connected to the peripheral part of the first through hole 210 through an adhesive layer. The outer decorative ring 330 is sleeved outside the first side wall 322. The second bracket 340 (for example, a texture decorative bracket) covers the second side plate 324 of the inner decorative ring 320 and the side of the outer decorative ring 330 facing away from the cover body 200. And the second bracket 340 can be hermetically connected to the second side plate 324 of the inner decorative ring 320 and the outer decorative ring 330 respectively through adhesive layers formed by dispensing glue.

[0065] Combined with Figure 8 and Figure 9 , the second bracket 340 is correspondingly provided with three fourth through holes 341. Combined with Figure 1 , Figure 3 and Figure 4 , the light-transmitting parts of each camera module 400 are correspondingly inserted into the fourth through holes 341 one by one. The lens 350 covers the second bracket 340 through the heat-conducting member 360.

[0066] It should be noted that the first through hole 210 of the cover body 200 is mainly waterproof-sealed by the inner decorative ring 320, the second bracket 340, the heat-conducting member 360 and the lens 350. Since the inner decorative ring 320 is provided with a second through hole 321 and the second through hole 321 is provided with a waterproof and breathable member 710, the inside of the electronic device 1 can communicate with the external environment through the second through hole 321 provided with the waterproof and breathable member 710, so that the inside of the electronic device 1 and the external environment are in a state of water vapor balance and air pressure balance.

[0067] Combined with Figure 1 , Figure 3 and Figure 4 , when the first camera module is inserted into the seventh through hole of the circuit board 120 and the second camera module and the third camera module are fixed on the circuit board 120, the area surrounded by the frame body 110, the circuit board 120, the first bracket 130, the second bracket 340, the heat-conducting member 360 and the lens 350 forms a receiving cavity 500. The second side wall 134 of the first bracket 130 is provided with a fifth through hole 132, and the fifth through hole 132 is opposite to the second through hole 321 of the inner decorative ring 320, so that the receiving cavity 500 is breathable and communicated with the external environment through the fifth through hole 132 and the ventilation channel 310.

[0068] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or apparatus.

[0069] Although the embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the embodiments of the present application, and the scope of the embodiments of the present application is defined by the appended claims and their equivalents.
