Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 365,759, filed on June 2, 2022, and entitled “SEAL FORAN ELECTRONIC DEVICE,” the entire disclosure of which is hereby incorporated by reference. Technical Field

[0003] The described embodiments generally relate to protection of electronic devices and components therein. More specifically, the present embodiments relate to dust seals that separate electrical components and are configured to aid in assembly. Background Art

[0004] An electronic device may include internal components that communicate, interface, or interact in some way with the environment outside the device. Typically, these internal components may be negatively affected by the external environment, including interference from external light and dust. Such components may also interfere with each other and adversely affect their intended functions. In addition, components are prone to degradation due to dust and debris or light interference.

[0005] However, conventional electronic devices and components are not designed to withstand external forces while protecting internal components from dust damage and light interference. In addition, conventional designs that attempt to mitigate such interference make it difficult or expensive to assemble electronic devices. Furthermore, conventional designs tend to be heavy and may be bulky or lack aesthetically and tactilely pleasing design features. Summary of the invention

[0021] Reference will now be made specifically to the representative examples shown in the accompanying drawings. It should be understood that the following description is not intended to limit the examples to a preferred example. On the contrary, the following description is intended to cover substitutions, modifications and equivalents that may be included within the spirit and scope of the examples defined by the appended claims.

[0022] The following disclosure relates to seals, electronic components protected by seals, and arrangements for electronic components within electronic devices. Examples of electronic devices described herein include portable electronic devices and personal computing devices designed for use in a variety of environments. For example, many people carry mobile phones with them day and night, including during outdoor activities or in the office or home. Electronic watches are also worn and used in many environments, including outdoor leisure, immersed in water, rain, sunlight, etc. A recent technological development is the use of virtual reality and / or alternative reality (VR / AR) headsets that can be worn and used indoors or outdoors during the day or night.

[0023] Any of these examples of electronic devices may include multiple components that interact with the external environment. These components may include sensors, antennas, cameras, or other similar electronic components. In the example of the AR / VR headset given above, one or more sensors may include a tracking sensor, an ambient light sensor, and / or a flicker sensor. In addition, one or more outward-facing lights (such as light emitting diodes (LEDs)) may be placed and tracked using an external camera to form accurate positioning of the VR / AR headset and / or other components.

[0024] The electronic device described in the present disclosure includes components and arrangements configured to protect LED, antenna, sensor and / or other components mentioned above that are communicated with the external environment from the light and debris that may otherwise damage or adversely affect the components. More specifically, the present disclosure describes seals and electronic components, and seals and electronic components ensure that the internal components can fully function when needed without being disturbed by the external environment of the electronic device, and without the risk of damaging the internal components. This interference may include light, debris or moisture. Such internal components may include but are not limited to cameras, LED, ambient light sensors, flicker sensors and other sensors, etc. These and other internal components may be arranged to be adjacent to or below the alignment of one or more holes / ports of the electronic device, wherein the seal is arranged between the hole / vent and the internal electronic components. In this way, the seal described herein can serve as a barrier between the internal components and the external environment or the internal components and other internal components, while also achieving the correct operation of the internal components.

[0025] In a specific example, an electronic device includes a housing defining an interior volume and a hole defined by the housing. An electronic component may be disposed within the interior volume, and a seal may be disposed between the hole and the electronic component, the seal being configured to protect the electronic component within the housing.

[0026] In a specific example, the electronic component includes a light emitting component coupled to the base support. The electronic device may include other electronic components that are sensitive to light. A seal may be provided and configured between the light emitting component and the light sensitive component to prevent and / or minimize light interference.

[0027] The seals described herein block light having a wavelength in the visible light range, and light having a wavelength extending into the ultraviolet and infrared ranges. The seals also prevent dust and / or debris from entering the housing from holes and / or any vents provided on the housing of the electronic device. The seals described herein are also compressible to facilitate assembly of the electronic device. In addition, the seals and assemblies described herein are durable and damage-resistant. The seals can be die-cut, and the components of the electronic device can be made of materials intended to minimize the weight of the components and / or the electronic device.

[0028] For example, the seals described herein may include open-cell or closed-cell foams. The seals may engage a bracket or base support of an electronic device with an interference fit. In some examples, the seals may include a seal configured to surround a light-emitting component. Because the light-emitting component is mounted to one end of the base support in some examples, the seal may be die-cut to precisely interfere with the base support to separate the light-emitting component from other electronic components disposed in the electronic device and facilitate upper and lower assembly orientation.

[0029] The following will refer to Figures 1 to 7C to discuss these examples and other examples. However, those skilled in the art will readily appreciate that the detailed description of these figures given herein is for illustrative purposes only and should not be construed as limiting. In addition, as used herein, a system, method, article, component, feature, or sub-feature comprising at least one of a first option, a second option, or a third option should be understood to refer to a system, method, article, component, feature, or sub-feature that may include one of each listed option (e.g., only one first option, only one second option, only one third option), multiple of a single listed option (e.g., two or more first options), two options at the same time (e.g., one first option and one second option), or a combination thereof (e.g., two first options and one second option).

[0030] In the present disclosure, any example of an electronic device incorporating the housing, housing, electronic components, seals, and configurations described herein may be incorporated into the present teachings and methods. The drawings herein are for illustrative purposes only to show example embodiments of the devices and electronic components and configurations of the present disclosure. Seals, base supports, housings, and seal / housing configurations may be implemented in any number of electronic devices.

[0031] Figure 1 An example of an electronic computing device 10 having a compact design is shown. Device 10 is a laptop computer having multiple functions, including video and audio output, Internet connection, electronic communication capabilities, and computing functions. These functions may be implemented by a variety of components, including a processor, antenna, display components, screens and lights, input components (such as keyboards and touch pads), etc. Many of these electronic components may include sensors and / or light emitting components that may interfere with nearby components of device 10. These components may be isolated by the present exemplary systems and methods for proper operation.

[0032] In one example, the device 10 may include a housing 12 or multiple housings defining an interior volume. The sensor and / or light emitting components may be disposed within the interior volume or outside the interior volume. In one example, the components may communicate with the surrounding environment through the housing. For example, the light emitting component may be an LED disposed at or on the housing 12, or within the housing 12 and directing light through an aperture defined by the housing 12. The sensor components and systems described herein may be disposed within the interior volume defined by the housing 12. Figure 2 Another exemplary electronic device is described in detail.

[0033] Figure 2 Another example of an electronic device 20 is shown, which includes a smart phone having a housing 22 that defines an interior volume and an exterior surface of the device 20. The smart phone 20 may also include a plurality of electronic components, including a display / touch screen and / or sensors, and one or more lights 24 may be disposed at various locations on, above, or within the housing 22, as shown. In one example, the light 24 may be a notification light or visual icon disposed within or outside the interior volume defined by the housing 22 of the device 20. In one example, the light 24 may be in communication with the surrounding environment through the housing 22. For example, the one or more lights 24 may be LEDs disposed at or on or within the housing 22 and directing light through an aperture defined by the housing 22.

[0034] exist Figure 2 In the example shown, the light 24 may include an LED that may interfere with the photosensitive component. The light emitting components and photosensitive components and systems described herein may be included in the smart phone 20 while being isolated from each other to prevent degradation and interference of the light emitting components with the photosensitive components. Figure 3 Another exemplary electronic device is described in detail.

[0035] Figure 3 Another example of an electronic device is shown, which includes a head-mounted display 30 having a display portion 36. The display portion 36 may include a housing 32 defining an internal volume and one or more light-emitting and / or light-sensitive electronic components, including an outward-facing light 34. The display portion 36 may also include a display screen 39 or other display components that project light to the user's eyes when the user wears the head-mounted display 30. The light 34 may include one or more LEDs. The light 34 and / or the light-sensitive component may be disposed at various locations on, above, or inside the housing 32, as shown. In one example, the light 34 may be a notification light or visual icon disposed within or outside the internal volume defined by the housing 32 of the head-mounted display 30. In one example, the light 34 may be in communication with the surrounding environment through the housing 32. The light-sensitive component may include an ambient light sensor, a camera, and / or a flicker sensor. One or more of the lights 34 may be LEDs disposed at or on the housing 32 or within the housing 32 and directing light through a hole defined by the housing 32. In other embodiments, the light 34 may be an infrared light or other invisible light used to assist sensors or other components of the head mounted display 30 by illuminating an object with light of a known frequency.

[0036] Figures 1 to 3 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figures 1 to 3 The following are examples of devices, features, components and parts shown. Figure 4 Further details of the present sealing system and method are provided.

[0037] Figure 4A cross section of an electronic device 100 is shown. The electronic device may include any of the electronic devices described above. The electronic device may include a housing 105. The housing may include a first wall 110. In some examples, the first wall 110 may include an outer wall of the electronic device 100 or may include a wall that separates a chamber or compartment within the electronic device 100. The housing 105 may include a base support 115 coupled to the first wall 110. The base support 115 may include a base bracket or support for the electronic device 100 and / or electronic components disposed within the housing 105. In some examples, the base support 115 may include one or more rigid metal materials, including steel, stainless steel, magnesium, and / or titanium. In some examples, the base support 115 may include plastic and / or plastic components to reduce the weight of the electronic device 100. The base support 115 may be cylindrical in shape or may include a cubic shape, and may be a solid material or hollow to reduce the weight of the electronic device 100. The base support 115 may include a first surface 120 coupled to the first wall 110 by an adhesive or any non-limiting fastening method and / or device. The electronic component may be coupled to a second surface 125 of the base support 115. The second surface 125 of the base support 115 may be configured to be opposite the first surface 120. The electronic component may include a light emitting component 130 (e.g., a light emitting diode or LED).

[0038] The electronic device 100 may further include a second wall 135 disposed above the base support 115. The first wall 110 and the second wall 135 may form a housing 140 within the housing 105, and the base support 115 may be disposed within the housing 140. In some examples, electronic components 145 may also be disposed within the housing 140. The electronic components 145 may include photosensitive components, which in some examples are interfered with by light from the light emitting component 130. The electronic components 145 may be mounted to the second base support or may be directly coupled to the first wall 110 and / or the second wall 135.

[0039] The electronic device 100 may further include a seal 150 surrounding the light emitting component 130. The seal 150 may be disposed between the base support 115 and the second wall 135. In some examples, the seal 150 separates the electronic component 145 from the light emitting component 130. The seal 150 may be configured to block the light emitting component 130 from the electronic component 145. -8 m and about 10 -3m. In other words, seal 150 can block light in the visible light region, the ultraviolet region, and the infrared region. Seal 150 can also prevent dust and / or debris from passing between base support 115 and second wall 135. In some examples, seal 150 surrounds light emitting component 130 on all sides. Thus, seal 150 engages base support 115 around the periphery of the upper portion of base support 115 or the second surface 125 of base support 115. In some examples, second surface 125 includes the same surface on which light emitting component 130 is disposed.

[0040] In some examples, the base support 115 defines a flange 155. The seal 150 may surround an upper portion of the base support 115 and contact or engage an upper surface of the flange 155. In this way, the seal 150 and the base support 115 may be engaged with an interference fit. For example, the radial seal 150 may be disposed between the base support 115 and the second wall 135 with a press fit or a friction fit. The seal 150 and the base support 115 may be held together by friction after the housing 105 and other components are assembled. For example, the seal 150 may be compressed between the second wall 135 and the second surface 125 or flange 155 of the base support 115 to separate or seal the light emitting component 130 from the electronic component 145. In some examples, the seal 150 may separate and / or seal the housing 140 from an area or environment outside the housing 105 or outside the electronic device 100.

[0041] In some examples, seal 150 may be die cut. Seal 150 may be cut into a precise shape by a metal "die" during production. The die cutting process may provide seal 150 with a precise shape and characteristics to properly assemble electronic device 100 due to the precise shape (e.g., radial) and size of seal 150 to properly seal against light, dust, and other debris and to properly fit second wall 135 and base support 115 (including flange 155 defined thereby).

[0042] In some examples, the seal 150 may include a silicone material. The silicone seal 150 may be inexpensive to manufacture and, when properly shaped, provide the desired compressibility and an interference fit with the base support 115. In some examples, the silicone seal 150 may include a foaming agent and / or be dyed to block light from the external environment and / or the light emitting component 130 from being transmitted to the electronic components 145 within the housing 140. The seal 150 may include portions formed of different materials. In some examples, the seal 150 may include a plastic gasket 160. The plastic gasket 160 may be included as a component of the seal 150 to reduce the weight of the seal 150, and thus may reduce the weight of the electronic device 100. In some examples, the plastic gasket 160 may contact the base support 115. In some examples, the plastic gasket 160 may contact the flange 155 and / or the upper portion of the base support 115. The plastic gasket 160 may also be impenetrable or resistant to light, dust, and / or debris. The seal may further include a foam material 165 coupled to the plastic gasket 160 .

[0043] Figure 4 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 4 Examples of devices, features, components and parts are shown below. Figure 5 Further details of the seal are provided.

[0044] Now refer to Figure 5 , showing Figure 4 150. In some examples, the plastic gasket 160 can be coupled to the foam material 165 using a pressure sensitive adhesive 170 or any suitable adhesive. The plastic gasket 160 can form a precise seal with the base support 115 and can be cheaper to manufacture than silicone and / or seals that only include foam material. The foam material 165 can be compressed between the plastic gasket 160 and the second wall 135, such as Figure 4 As shown. The plastic gasket 160 may include a bottom surface 162 coupled to the base support 115. The plastic gasket 160 may be joined to the base support 115 with a pressure sensitive adhesive 170. The top surface of the plastic gasket 160 may also include a pressure sensitive adhesive 170 to couple the plastic gasket 160 to the foam material 165. In some examples, the foam material 165 may include a compressible open-cell or closed-cell foam to block light, dust, and / or debris.

[0045] Figure 5 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 5 Examples of devices, features, components and parts are shown below. Figures 6 to 7C Additional configurations of the seals described herein are provided.

[0046] Figure 6 An electronic device 200 having a housing 205 and electronic components therein is shown. The electronic device 200 may include a head mounted device (e.g., device 30). In some examples, the electronic device 200 may include a first housing 210 in which a light emitting component 222 is disposed. The first housing may be defined at least in part by the housing 205, an inner wall 255, and an outer wall 240 defining an outer surface 242. The housing 205 may include a first wall 215. In some examples, the first wall 215 may include an outer wall of the electronic device 200, or may include a wall separating a chamber or compartment within the electronic device 200. The housing 205 may include a base support 220 coupled to the first wall 215. The base support 220 may include a first surface 225 coupled to the first wall 215 by an adhesive or any non-limiting fastening method and / or device. The electronic component may be coupled to a second surface 230 of the base support 220. The second surface 230 of the base support 220 may be opposite to the first surface 225. The light emitting component 222 may include a light emitting diode (LED).

[0047] The housing 205 may further include a second housing 230. The second housing 230 may include at least one photosensitive component 235 disposed therein. The second housing 230 may be defined by the housing 205 (including various inner and outer walls). In some examples, the photosensitive component 235 may include an optical sensor. In some examples, the photosensitive component 235 may include at least one of a camera, an ambient light sensor, or a flicker sensor. In some examples, the second housing 230 may include an outer surface 240 of the housing 205. In other words, one of the walls of the second housing 230 includes the outer surface 240 of the housing 205.

[0048] In some examples, the housing 205 may further define a third housing 245. The base support 220 may be disposed within the third housing 245. In some examples, the base support 220 may include a metal or plastic material. In some examples, the third housing 245 may include an inner surface 250 of the housing 205. In other words, one of the walls of the third housing 245 includes the inner surface 250 of the housing 205. In some examples, the housing 205 of the electronic device 200 includes an inner wall 255 that separates at least a portion of the second housing 230 from the third housing 245. In some examples, a seal 260 is included. The seal 260 may be coupled to the top portion or second surface 230 of the base support 220. The seal 260 may separate the first housing 210, the second housing 230, and the third housing 245. In other words, the seal 260 includes at least a portion of a wall or partition that separates the first housing 210, the second housing 230, and the third housing 245 from each other. In some examples, the seal 260 is impenetrable to dust, debris, and / or light. The seal can extend from the second surface 230 of the base support 220 through the inner wall 255 and be press-fitted to the outer surface 240 of the housing 205. Figure 6 In the configuration shown, the seal 260 is used to protect the photosensitive component 235 from the light emitting component 222 and to protect the photosensitive component 235 and the light emitting component 222 from debris and / or dust 265 present outside the housing 205 or within the third shell 245.

[0049] In some examples, dust 265 can enter the third housing 245 through the vent 270 or other holes. The seal 260 prevents or substantially prevents dust 265 or other debris (such as but not limited to water, dirt and smoke) from passing through to the first housing 210 or the second housing 230, which may include sensitive electronic components. The vent 270 may be included on the electronic device 200 for temperature control and / or heat dissipation. In some examples, the vent 270 may be included for the comfort and / or safety of the user of the electronic device 200. According to one example, the vent 270 may include a perforated material to cover the vent 270 or other holes in the electronic device. The size, location and number of perforations extending through such a material may be different for different examples. Such perforations may include openings defined by the material and extending through the material that are machined, laser cut or otherwise manufactured. Such openings may be sized and arranged to prevent particles of a certain size from the external environment from passing through the vent 270. Such openings may also be sized and include other types of filters to prevent moisture or other harmful debris from passing through the vent 270.

[0050] In some examples, the seal 260 can be cut and / or shaped to seal around the inner wall 255 and seal between the second surface 230 of the base support 220 and the outer surface 240 of the shell 205. The seal 260 may include a compressible foam and may be compressed in an interference fit or press fit between the outer surface 240 of the shell 205 and the top portion or second surface 230 of the base support 220. The seal 260 may include an open-cell polyurethane foam, which is lightweight and more compressible than closed-cell foam. In other examples, the seal 260 may include a silicone material. The seal 260 may include a reticulated polyurethane, PVC / nitrile, ethylene propylene diene monomer (EPDM) rubber or other suitable materials. The materials that can be used to produce the closed-cell foam of the seal 260 can vary greatly from ethylene-vinyl acetate (EVA), polyethylene, polystyrene, rubber to polypropylene, etc. The closed-cell foam may include trapped bubbles formed during the expansion and curing of the foam. The bubbles are permanently locked in one position because the trapped gas is very effective in increasing the insulating ability of the foam. The foam formed is solid and generally has a greater density than open cell foam, which enables the bubbles to lock in place. The properties of the foam make it vapor retarding and resistant to liquid water. In some examples, the material of the seal may be open cell, but may include sufficiently tortuous paths to limit or eliminate the passage of contaminants between the shells.

[0051] In some examples, the top portion of the base support 220 may include a flange (e.g., Figure 4 155 shown in FIG. 15 ). The seal 260 may surround an upper portion of the base support 220 and contact the flange. In some examples, the seal 260 may further include a plastic gasket (e.g., plastic gasket 160) that contacts the flange. The seal 260 may fit tightly to the base support 220. The tight fit may be used not only to seal the housing within the enclosure, but also to control and / or hold electronic components in place, which may improve the design of the electronic device 200, minimize noise and / or vibration, and reduce manufacturing costs.

[0052] Figure 6 Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Similarly, any of the features, components and / or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components and parts shown in other figures described herein. Figure 6 The following are examples of devices, features, components and parts shown. FIG. 7A to FIG. 7C Further details are provided of electronic devices incorporating the present arrangements.

[0053] FIG. 7A to FIG. 7CAn electronic device 300 is shown. Fig. 7A 305 and a dust seal 310 surrounding the electronic component 305 within an electronic device 300 according to one example. In some examples, the dust seal 310 can be coupled to a base support 315. The dust seal 310 can be coupled to the base support 315 via an interference fit. In some examples, the dust seal 310 can be bonded to the base support 315 with an adhesive (e.g., Figure 5 ) is adhered to the base support 315. In some examples, the electronic component 305 may include a light emitting component (e.g., Figure 6 222 shown in FIG. 2 ). The electronic device 300 may further include a flexible printed circuit board or flexible printed circuit (flexible PCB) 320. At least a portion of the flexible PCB 320 may be disposed between the dust seal 310 and the base support 315. In some examples, the flexible PCB may include an arrangement of printed circuits and / or components utilizing a flexible material having a flexible coating. The flexible printed circuit board may include a metal trace layer, typically copper, combined with a dielectric layer. The thickness of the metal layer may be very thin (<.0001”) to very thick (>.010”) and the dielectric thickness may also vary. The flexible PCB may be included in the electronic device 300 to reduce the assembly process and improve reliability. The flexible PCB may be used as a connector, a power source, and may also be used as a complete circuit assembled with components such as the electronic component 305. The benefit of including the flexible PCB 320 in the electronic device 300 is to connect the electronic component 305 to other components and / or a power source (not shown) and to have the flexible PCB 320 disposed between the dust seal 310 and the base support 315. In some examples, dust seal 310 holds the flexible PCB adjacent to base support 315 .

[0054] Figure 7B A cross-sectional view of a portion of an electronic device 300 is shown. A flexible PCB 320 can be coupled to an electronic component 305. In some examples, the electronic component 305 can include a light emitting device mounted to a base support 315. In some examples, the light emitting device can be coupled to a top surface 325 of the flexible PCB 320, and a bottom surface 330 of the flexible PCB 320 can be coupled to the base support 315. A dust seal 310 can surround the light emitting device. In some examples, the dust seal 310 is impenetrable or resistant to light, dust, and / or debris. Figure 7BA base support 315 having a flange 335 is shown. The dust seal 310 can extend from an upper portion of the base support 315 adjacent to the base support 315 and through the dust seal 310. In some examples, the flange 335 can include a cutout portion. The cutout portion can have a width of the flexible PCB to minimize folding of the PCB and keep the flexible PCB 320 adjacent to the base support 315. Figure 7C , the flexible PCB 320 may also include an adhesive 340 on the bottom surface 330 to hold the flexible PCB 320 adjacent to the base support 315 . Figure 7C Components of a dust seal are shown, each configured to retain the flexible PCB 320 and / or prevent dust and / or debris from entering the electronic device.

[0055] In some examples, the dust seal 310 can act as a radial seal to apply a radial force 345 to the flexible PCB 320, thereby holding the flexible PCB 320 adjacent to the base support 315. In other words, the dust seal 310 prevents access paths and helps the adhesive 340 with flexibility management by applying a compressive normal force that prevents the flexible PCB 320 from delaminating from the base support 315. The dust seal 310 can also act as a compression seal to apply a compressive force 350, thereby compressing the dust seal 310 between the housing wall 355 and the base support 315. In this way, the dust seal 310 can include a compressible foam. The dust seal 310 can be coupled to the base support 315 and engaged to the base support and the housing wall 355 with an interference fit. As described in other examples above, the housing wall 355 of the electronic device 300 can include a vent 360 and / or other holes. Figure 7C The dust seal 310 is configured to block a dust inlet path 365. Because the dust seal 310 includes a compressible foam and is joined with a compression seal and a radial seal, the dust inlet path 365 is closed and the dust seal 310 is impenetrable to dust and / or debris. In some examples, the dust seal 310 is also opaque.

[0056] In some examples, the components described above for the electronic device examples (e.g., electronic devices 100, 200, and / or 300) can assist in the assembly of an electronic device housing (e.g., housing 305). In some examples, the assembly process can require the use of a minimum amount of metal material for the base support 315 to maximize the available distance that can be used between the components. The assembly method can also require that the flange 335 be minimized so that the base support 315 does not interfere with the inclusion / installation of other electronic components (e.g., electronic components 145) during assembly. In other words, due to the material used for the base support 315 and / or the shape of the base support 315, the base support 315 can be installed first, and then other electronic components (e.g., electronic components 145) can be installed after the base support 315, followed by placing the dust seal 310 on or around the base support, and the housing wall (e.g., housing wall 355) can be installed last to compress the dust seal 310 between the housing wall 355 and the base support 315 with an interference fit. In other words, the present exemplary sealing systems and methods facilitate top or front assembly of the device while ensuring a secure light and / or dust seal between the sections.
