[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] In the related art, the folding screen of a foldable electronic device (such as a foldable mobile phone, foldable tablet computer, etc.) needs to be provided with a screen pressing strip in the bending area to protect the components between the bending area and the middle frame. The screen pressing strip needs to be made of a flexible material, and the flexible material enables the screen pressing strip to switch its form according to the change of the folding and unfolding state of the foldable electronic device, that is, when the device is folded, it fits with the screen surface to form a folded corner protection, and when the device is unfolded, it is flat with the screen surface.

[0038] However, since the flexible material of the screen pressing strip is fatigue-prone, after repeated folding and unfolding, the screen pressing strip will gradually develop cracks and breakages.

[0039] In order to solve the above technical problem, a middle frame assembly and an electronic device are provided according to an embodiment of the present disclosure.

[0040] Figure 1 The figure is a schematic diagram showing an electronic device in an unfolded state according to an exemplary embodiment. Figure 2 is a schematic diagram showing a middle frame assembly in a first form according to an exemplary embodiment.

[0041] In some embodiments, Figure 2 As shown, the middle frame assembly 1 includes a screen pressing strip, which may include a plurality of screen pressing bodies 2, which are sequentially connected end to end to form a screen pressing strip. The middle frame assembly 1 also includes a middle frame body, which may include adjacent first frame bodies 111 and second frame bodies 112, the screen pressing body 2 at the head end of the plurality of screen pressing bodies 2 may be connected to the first frame body 111, and the screen pressing body 2 at the end of the plurality of screen pressing bodies 2 may be connected to the second frame body 112. That is, one end of the screen pressing body is connected to the first frame body 111, and the other end of the screen pressing body is connected to the second frame body 112.

[0042] like Figure 3 As shown, the screen pressing body 2 may include a first connecting portion 21 and a second connecting portion 22 , wherein the first connecting portion 21 of any screen pressing body 2 may be movably connected to the second connecting portion 22 of an adjacent screen pressing body 2 .

[0043] In this embodiment, through the active connection of multiple screen pressing bodies 2, it is achieved that during the repeated folding and unfolding of the foldable electronic device, the middle frame assembly 1 can switch the form according to the change of the folding and unfolding state of the electronic device, keep in contact with the screen surface, and play a protective role, and the active connection can enhance the overall flexibility of the middle frame assembly 1, overcoming the shortcomings of the related art that the screen pressing strip made of flexible materials will gradually produce cracks and fractures. In summary, the present disclosure improves the fatigue resistance of the middle frame assembly 1, extends the service life of the middle frame assembly 1, and solves the technical problem of the easy damage of the screen pressing strip in the related art.

[0044] Specifically, in the related art, the screen pressing strip is made of a whole flexible material. During repeated folding, the flexible material will fatigue and gradually crack. This is because during the folding process, different positions of the screen pressing strip will be subjected to different tensile or compressive deformations, and the whole flexible material cannot adapt to this non-uniform strain, resulting in local stress concentration and accelerated fatigue failure.

[0045] The middle frame assembly 1 in the present disclosure is composed of multiple screen pressing bodies 2 connected by movable connections. The movable connection allows a certain degree of freedom of movement between adjacent screen pressing bodies 2. During the folding process, the screen pressing bodies 2 at different positions can move relative to each other and displace each other, thereby dispersing local strain and avoiding strain fatigue of the screen pressing body 2 itself.

[0046] It is understandable that the screen pressing body 2 in this embodiment can be a single pressure component constituting the middle frame assembly 1. For example, the screen pressing body 2 can be made of a rigid material, such as metal or ceramic. It can also be a component made of a material with a supporting function, such as engineering plastic or silicone. However, the present disclosure does not specifically limit the type of the screen pressing body 2, that is, those skilled in the art can set or adjust it according to actual conditions, as long as the screen pressing body 2 is a pressure component constituting the middle frame assembly 1.

[0047] It can be understood that the movable connection can be a connection method that allows a certain degree of freedom of movement between adjacent screen bodies 2. The movable connection method allows adjacent screen bodies 2 to undergo relative displacement or rotation in a connected state. In some embodiments, the first connection portion 21 of any screen body 2 can be rotatably connected to the second connection portion 22 of an adjacent screen body 2, or the first connection portion 21 of any screen body 2 can be slidably connected to the second connection portion 22 of an adjacent screen body 2. However, the present disclosure is not limited to this. In other embodiments, the movable connection can also be a loose connection or an elastic connection, etc., but the present disclosure does not specifically limit the type of movable connection, that is, those skilled in the art can set or adjust it according to actual conditions, as long as the movable connection allows a certain degree of freedom of movement between adjacent screen bodies 2.

[0048] It can be understood that the first connection part 21 and the second connection part 22 can be the parts on the screen body 2 for connecting with the adjacent screen body 2, and the first connection part 21 and the second connection part 22 can be used to realize the movable connection or sequential connection between multiple screen bodies 2. For example, the first connection part 21 on one screen body 2 can be connected to the second connection part 22 on the adjacent screen body 2, and then the first connection part 21 of the adjacent screen body 2 is connected to the second connection part 22 of another adjacent screen body 2, and so on, so as to realize the chain connection of multiple screen bodies 2.

[0049] Figure 3 It is an exploded view of a middle frame assembly according to an exemplary embodiment viewed from a first angle. Figure 4 It is an exploded view of a middle frame assembly according to an exemplary embodiment viewed from a second angle.

[0050] In one possible scenario, Figure 2 or Figure 3 or Figure 4 As shown, the movable connection between the multiple screen pressing bodies 2 can be a rotating connection, the first connection part 21 can be set as a cylindrical shaft structure, and the second connection part 22 can be set as a bearing hole structure matched with the shaft structure. The relative rotation between the multiple screen pressing bodies 2 can be achieved through the combination of the shaft and the hole.

[0051] In another possible case, the movable connection between the multiple screen pressing bodies 2 can be a sliding connection, the first connection part 21 can be set as a boss structure, and the second connection part 22 can be set as a groove structure that cooperates with the boss. The relative movement between the multiple screen pressing bodies 2 can be achieved through the sliding cooperation between the boss and the groove. In addition, it should be noted that the screen pressing body 2 can also be set as a circle. For example, by setting the first connection part 21 as a boss structure and the second connection part 22 as a groove structure on the circular screen pressing body 2, the relative movement between the screen pressing bodies 2 can also be achieved through the cooperation between the first connection part 21 and the second connection part 22.

[0052] It is understandable that the present disclosure does not specifically limit the specific form of the first connection part 21 and / or the second connection part 22. The above situation is only an exemplary description of the forms in which the first connection part 21 and / or the second connection part 22 can exist, but is not limited to the situations described in the above embodiments. As long as the setting of the first connection part 21 and / or the second connection part 22 can achieve a movable connection, it is all right. In other words, as long as it is under this condition, those skilled in the art can adjust the specific form of the first connection part 21 and / or the second connection part 22 according to the actual situation.

[0053] In the related art, the display module of the foldable electronic device needs to withstand mechanical deformation during repeated folding. If the screen pressure bar becomes loose or fails as a whole during the folding process, it will not be able to provide sufficient pressure on the display module.

[0054] Figure 5 1 is a front view of a middle frame assembly in a first form according to an exemplary embodiment. Figure 6 1 is a front view of a middle frame assembly in a second form according to an exemplary embodiment.

[0055] In some embodiments, when the first connection portion 21 of any screen pressing body 2 is rotatably connected to the second connection portion 22 of the adjacent screen pressing body 2, as shown in FIG. Figure 5 or Figure 6 As shown, the middle frame assembly 1 can have a first form and a second form. In the first form, the plurality of screen pressing bodies 2 can limit each other when rotating in the first direction D1, and / or in the second form, the plurality of screen pressing bodies 2 can limit each other when rotating in the second direction D2. The first direction D1 can be opposite to the second direction D2.

[0056] In this embodiment, two stable working modes are realized by the rotation connection between the screen pressing bodies 2 and the mutual limitation between the multiple screen pressing bodies 2. That is, in the first mode, the screen pressing bodies 2 will limit each other when rotating in the first direction D1, so that the middle frame assembly 1 can form a rigid whole, thereby providing sufficient pressure or support for the display module 120. In the second mode, the screen pressing bodies 2 will also limit each other when rotating in the second direction D2, and can also form a rigid whole, thereby providing sufficient pressure or support for the display module 120.

[0057] It is understandable that the overall rigidity of the middle frame assembly 1 in the first form or the second form can ensure that the middle frame assembly 1 can provide stable pressure or support for the display module 120. Specifically, Figure 6 As shown, in the folded state, when the multiple screen pressing bodies 2 rotate in the first direction D1, they will limit each other and form a stable folded state. At this time, the middle frame assembly 1 as a whole shows rigidity and will not continue to deform in the first direction D1. Figure 5 As shown, in the unfolded state, the screen pressing body 2 is mutually limited when rotating in the second direction D2, and the middle frame assembly 1 as a whole also exhibits rigidity and will not continue to deform in the second direction D2. In other words, in any specific form, since the rotation of the screen pressing body 2 is limited, there will be no looseness or relative displacement, so when the middle frame assembly 1 works in this form, it exhibits rigidity as a whole and will not have undesirable deformation. This rigidity ensures that the middle frame assembly 1 can provide stable pressure or support for the display module 120.

[0058] In some embodiments, the first state may be a folded state of the middle frame assembly 1 , and / or the second state may be an unfolded state of the middle frame assembly 1 .

[0059] It can be understood that the first form and the second form of the middle frame assembly 1 can be two working forms of the middle frame assembly 1, namely the folded state and the unfolded state, and the rotation directions of the corresponding screen pressing body 2 in these two states are opposite. For example, the first direction D1 can be a direction toward the inside of the display module 120, and the second direction D2 can be a direction toward the outside of the display module 120. For another example, the first direction D1 can be a counterclockwise direction, and the second direction D2 can be a clockwise direction.

[0060] In some embodiments, the first form and the second form conversion process of the middle frame assembly 1 can be as follows.

[0061] When the middle frame assembly 1 is converted from the second form to the first form, each screen pressing body 2 can rotate in the first direction D1 and limit each other to form a rigid folding form.

[0062] When the middle frame assembly 1 is converted from the first form to the second form, each screen pressing body 2 can rotate in a second direction D2 opposite to the first direction D1 and limit each other, thereby forming a rigid unfolded form.

[0063] In some embodiments, Figure 3 or Figure 4 As shown, the screen pressing body 2 may include a first end 23 and a second end 24, the first end 23 of any screen pressing body 2 may be opposite to the second end 24 of an adjacent screen pressing body 2, the first connecting portion 21 may be located at the first end 23, and the second connecting portion 22 may be located at the second end 24. Thus, by providing the first connecting portion 21 and the second connecting portion 22 at both ends of the screen pressing body 2, a sequential connection between two adjacent screen pressing bodies 2 may be achieved, thereby forming the entire middle frame assembly 1.

[0064] In some embodiments, Figure 3 or Figure 4 As shown, the first end 23 and the second end 24 of each screen pressing body 2 may be oriented in opposite directions. By sequentially connecting the first ends 23 and the second ends 24 oriented in opposite directions, the middle frame assembly 1 composed of the plurality of screen pressing bodies 2 can present a multi-segment regular structure, which is beneficial for controlling the moving direction of each screen pressing body 2 when the middle frame assembly 1 switches between the first form and the second form.

[0065] In this disclosure, Figure 5As shown, when the screen pressing strip is in the flattened state, there may be a gap between the opposite ends of two adjacent screen pressing bodies 2. Specifically, there may be a gap between the first end 23 of a screen pressing body 2 and the second end 24 of the screen pressing body 2 adjacent thereto. According to such a configuration, when the screen pressing strip begins to fold from the flattened state, the gap between the first end 23 of a screen pressing body 2 and the second end 24 of the screen pressing body 2 adjacent thereto may become smaller, and when there is no longer a gap between the first end 23 of a screen pressing body 2 and the second end 24 of the screen pressing body 2 adjacent thereto, the two screen pressing bodies 2 form a limiting relationship with each other, limiting the two from getting closer. Correspondingly, when the screen pressing strip begins to unfold from the folded state, the gap between the first end 23 of a screen pressing body 2 and the second end 24 of the screen pressing body 2 adjacent thereto may become larger.

[0066] For example, the first end 23 of the screen pressing body 2 may have a first limiting portion 231, and the second end 24 may have a second limiting portion 241. The first limiting portions 231 and the second limiting portions 241 of two adjacent screen pressing bodies 2 are opposite to each other. In the first form, the first limiting portion 231 of any screen pressing body 2 and the second limiting portion 241 of the adjacent screen pressing body 2 are mutually limited. In some embodiments, Figure 5 or Figure 6 As shown, the first end 23 may have a first limiting portion 231 and a third limiting portion 232, and the second end 24 may have a second limiting portion 241 and a fourth limiting portion 242. In the first form, the first limiting portion 231 of any screen pressing body 2 and the second limiting portion 241 of the adjacent screen pressing body 2 may limit each other, and / or in the second form, the third limiting portion 232 of any screen pressing body 2 and the fourth limiting portion 242 of the adjacent screen pressing body 2 may limit each other. In this way, by providing a plurality of limiting portions at the first end 23 and the second end 24 of the screen pressing body 2, and making different limiting portions limit in different forms, the controllable rotation and limiting of the middle frame assembly 1 between the two forms can be achieved, and the rigidity in the two forms can be ensured.

[0067] It can be further understood that the first limiting portion 231 can be provided at the first end 23 of the screen pressing body 2, and is used for limiting the position of the first limiting portion 241 of the adjacent screen pressing body 2 in the first form.

[0068] The third limiting portion 232 may be disposed at the first end 23 of the screen pressing body 2, and is used for limiting mutual positioning with the fourth limiting portion 242 of the adjacent screen pressing body 2 in the second form.

[0069] The second limiting portion 241 may be disposed at the second end 24 of the screen pressing body 2 , and is used to limit the first limiting portion 231 of the adjacent screen pressing body 2 in the first form.

[0070] The fourth limiting portion 242 may be disposed at the second end 24 of the screen pressing body 2, and is used to limit the third limiting portion 232 of the adjacent screen pressing body 2 in the second state. Figure 5 As shown, the first limiting portion 231 and the second limiting portion 241 can be mutually matched inclined surfaces, that is, the two inclined surfaces can abut against each other to form mutual limiting. The third limiting portion 232 and the fourth limiting portion 242 can be mutually matched planes, that is, the two planes can abut against each other to form mutual limiting.

[0071] Alternatively, in another possible case, the first limiting portion 231 and the second limiting portion 241 may also be tooth-shaped structures, that is, the two can achieve limiting by meshing of the tooth-shaped structures. The third limiting portion 232 and the fourth limiting portion 242 may also be matching slots, that is, the two can achieve limiting by engaging the slots.

[0072] It is understandable that the present disclosure does not specifically limit the specific forms of the first limiting portion 231, the third limiting portion 232, the second limiting portion 241 and the fourth limiting portion 242. The above situation is only an exemplary description of the forms in which the first limiting portion 231, the third limiting portion 232, the second limiting portion 241 and the fourth limiting portion 242 can exist, but is not limited to the situations described in the above embodiments. As long as the first limiting portion 231 and the second limiting portion 241 can be mutually limited in the first direction D1 in the first state, and the third limiting portion 232 and the fourth limiting portion 242 can be mutually limited in the second direction D2 in the second state. In other words, as long as it is under this condition, those skilled in the art can adjust the specific forms of the first limiting portion 231, the third limiting portion 232, the second limiting portion 241 and the fourth limiting portion 242 according to actual conditions.

[0073] The term "and / or" means that there are three situations. In the first situation, in the first form, the first limiting portion 231 of any screen pressing body 2 and the second limiting portion 241 of the adjacent screen pressing body 2 can limit each other; in the second situation, in the second form, the third limiting portion 232 of any screen pressing body 2 and the fourth limiting portion 242 of the adjacent screen pressing body 2 can limit each other; in the third situation, in the first form, the first limiting portion 231 of any screen pressing body 2 and the second limiting portion 241 of the adjacent screen pressing body 2 can limit each other, and, in the second form, the third limiting portion 232 of any screen pressing body 2 and the fourth limiting portion 242 of the adjacent screen pressing body 2 can limit each other.

[0074] In the disclosure, the first end 23 may be provided with a first connection portion 21, the second end 24 may be provided with a second connection portion 22, and two adjacent screen pressing bodies 2 may be connected through the first connection portion 21 and the second connection portion 22. For example, two adjacent screen pressing bodies 2 may be rotatably connected through the first connection portion 21 and the second connection portion 22.

[0075] In some embodiments, Figure 5 or Figure 6 As shown, the cross-section of the screen pressing body 2 can be trapezoidal, the first limiting portion 231, the third limiting portion 232, the second limiting portion 241 and the fourth limiting portion 242 can be located at the waist of the screen pressing body 2, the first connecting portion 21 can be located between the first limiting portion 231 and the third limiting portion 232, and the second connecting portion 22 can be located between the second limiting portion 241 and the fourth limiting portion 242.

[0076] In this embodiment, by setting a screen pressing body 2 with a trapezoidal cross section and setting a limit part and a connecting part at the waist of the screen pressing body 2, in the first form or the second form, adjacent screen pressing bodies 2 can be rigidly matched and limited by the bevel surface of the waist, thereby simplifying the limiting structure, without the need to set additional limiting components, and reducing the manufacturing difficulty and cost. In addition, the limiting parts on both sides of the connecting part can also play the role of rotation limiting, so that the screen pressing body 2 can only rotate within the range constrained by the limiting parts to avoid excessive rotation. By adjusting the spacing between the two limiting parts, the rotation angle range of the screen pressing body 2 is further controlled, and different forms of rotational movement are achieved.

[0077] Figure 7 is a schematic diagram showing an electronic device in a folded state according to an exemplary embodiment.

[0078] Based on the same concept, Figure 1 or Figure 7 As shown, the embodiment of the present disclosure may also provide an electronic device 100. The electronic device 100 may include the middle frame assembly 1 in any of the above embodiments.

[0079] It can be understood that the middle frame assembly 1 involved in the present disclosure can be applicable to any electronic device listed below.

[0080] It is understood that the electronic device 100 involved in the present disclosure may also be referred to as a terminal device, a terminal, a user equipment (UE), a mobile station (MS), an electronic device (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the electronic device 100 may be a handheld device, a vehicle-mounted device, etc. with a wireless connection function. At present, examples of the electronic device 100 may include: a smart phone (MobilePhone), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the electronic device 100 may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the electronic device 100. In the following description, a mobile phone is taken as an example for explanation, but the present disclosure is not limited to this.

[0081] It can be understood that the electronic device 100 provided in this embodiment can have all the beneficial effects of the above-mentioned middle frame assembly 1, and the present disclosure will not elaborate on them here.

[0082] In some embodiments, Figure 1 or Figure 7 As shown, the electronic device 100 may be a foldable electronic device, and the electronic device 100 may include a plurality of middle frames and a display module 120, the display module 120 may include a bendable portion 121, and the middle frame assembly 1 may cover the bendable portion 121. By covering the bendable portion 121 with the middle frame assembly 1, the bendable portion 121 may be effectively supported and protected, thereby improving the overall folding performance of the foldable electronic device.

[0083] It is understandable that the foldable electronic device can be an electronic device 100 that has a stronger portability through a folding design and can provide a larger screen for use after unfolding. The foldable electronic device can have at least two states, one is an unfolded state and the other is a folded state. The foldable electronic device can be exemplified by a foldable mobile phone or a foldable tablet computer, etc., but the present disclosure does not specifically limit the type of foldable electronic device, that is, those skilled in the art can set or adjust according to actual conditions, as long as the foldable electronic device has at least two states, one is an unfolded state and the other is a folded state.

[0084] It is understandable that the multiple middle frames may be different parts of the frame of the foldable electronic device. Since the foldable electronic device can be folded, its frame needs to be divided into multiple parts. The multiple middle frames can realize the conversion of the foldable electronic device between the folded state and the unfolded state.

[0085] It is understandable that the display module 120 may be a display screen component constituting a foldable electronic device. The display module 120 may provide a display screen for the foldable electronic device to display visual information such as images and videos. For example, the display module 120 may be a component that includes a display panel, a touch layer, a backlight module, etc. to form a display screen. In addition, the display module 120 may also include a bendable portion 121, which may realize the switching between the folded state and the unfolded state of the display module 120.

[0086] By further example, the display module 120 may be a flexible OLED display module, a flexible QLED display module or a flexible Micro-LED display module, etc., but the present disclosure does not specifically limit the type of the display module 120, that is, those skilled in the art may adjust its type according to actual conditions, as long as the display module 120 has a foldable portion.

[0087] In some embodiments, the middle frame assembly 1 may be located between the bendable portion 121 and the middle frame. Figure 1 or Figure 7 As shown, a portion of the middle frame assembly 1 may be located above the bendable portion 121 of the display module 120 , and another portion may be located above the gap between the display module 120 and the middle frame, thereby forming a seal or protection for the electronic device 100 .

[0088] In some embodiments, Figure 1 or Figure 7 As shown, the middle frame body may include adjacent first frame bodies 111 and second frame bodies 112, the screen pressing body 2 at the head end of the middle frame assembly 1 may be connected to the first frame body 111, and the screen pressing body 2 at the end of the middle frame assembly 1 may be connected to the second frame body 112. By connecting the two ends of the middle frame assembly 1 to two adjacent middle frames of the foldable electronic device, the middle frame assembly 1 can switch its own form following the folding movement of the middle frame, thereby switching its own form following the folding or unfolding state of the electronic device 100.

[0089] Among them, the head end of the middle frame assembly 1 can be relatively fixedly connected to the first frame body 111, for example, by welding, bonding, snap connection, threaded connection, etc., and the end of the middle frame assembly 1 can also be relatively fixedly connected to the second frame body 112, for example, by welding, bonding, snap connection, threaded connection, etc. However, the present disclosure does not specifically limit the connection method between the middle frame assembly 1 and the first frame body 111 or the second frame body 112, that is, those skilled in the art can set or adjust according to actual conditions, as long as the head end or the end of the middle frame assembly 1 is relatively fixedly connected to the first frame body 111 or the second frame body 112.

[0090] The disclosed embodiment realizes the function of the middle frame assembly 1 changing its own shape according to the change of the folding state of the electronic device 100 through the movable connection design of the screen pressing body 2. During the repeated folding and use of the electronic device 100, the middle frame assembly 1 can keep in contact with the surface of the display module 120, providing continuous and effective protection for the display module 120. This movable connection method enhances the overall flexibility of the middle frame assembly 1, and overcomes the fatigue fracture problem of the screen pressing strip in the related art using an integral flexible material.

[0091] It is to be understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.

[0092] It is further understood that the terms "first", "second", etc. are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or degree of importance. In fact, the expressions "first", "second", etc. can be used interchangeably. For example, without departing from the scope of the present disclosure, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information.

[0093] It will be further understood that the terms “center”, “longitudinal”, “lateral”, “front”, “back”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0094] It can be further understood that, unless otherwise specified, “connection” includes a direct connection without other components between the two, and also includes an indirect connection with other components between the two.

[0095] It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results. In certain environments, multitasking and parallel processing may be advantageous.
