Figure 8B is a diagram showing a second fluid path according to at least one exemplary embodiment. Figure 1A-1B Detailed cutaway view of the filter system and electronics unit.

[0079] refer to Fig. 8A and Figure 8BIn at least one exemplary embodiment, the filter system 105 is configured to be removably coupled to the electronic unit 100. For example, the filter system 105 can be threadedly coupled to the electronic unit 100 using the threads 630 of the vent 215. The threads 630 can be configured to engage with the inner surface of the cavity 810 defined by the electronic unit 100. In other exemplary embodiments, the filter system 105 can be removably coupled to the cavity 810 of the electronic unit 100 by a friction fit, a snap fit, or other engagement mechanism or component.

[0080] As mentioned above Figure 3 As described, the filtration system 105 may include a gasket 255. In at least one exemplary embodiment, the gasket 255 surrounds the first portion 245 of the vent 215, adjacent to the second portion 250. For example, the gasket 255 contacts at least a portion of the lower surface of the bottom 605 of the second portion 250 of the vent 215. Figures 8A-8B As shown, gasket 255 is between filter system 105 and electronics unit 100 and is configured to create a fluid seal.

[0081] In at least one exemplary embodiment, the filtration system 105 is configured to create at least two fluid pathways. Fig. 8A The inner surface of the third side wall 515 of the cover 205 , the second side 510 of the top wall 500 of the cover 205 , the outer surface of the second side wall 415 of the base 200 , and the top surface of the support wall 410 define a first fluid passage 800 .

[0082] In at least one exemplary embodiment, the first fluid pathway 800 is configured to direct liquid and / or solid particles that enter the filter system 105 from the surrounding environment away from the electronic unit 100. For example, the liquid and / or solid particles may enter the filter system 105 through the gap 700. The first fluid pathway 800 directs the liquid and / or solid particles from the gap 700 into the compartment 705 and then toward the opposite end or bottom of the filter system 105 by gravity, so that the liquid and / or solid particles exit the filter system 105 through one of the compartments 705 and the gap 700 at the opposite end of the filter system 105. The liquid and / or solid particles within the first fluid pathway 800 may be directed to the bottom of the filter system 105 through each of the compartments 705 defined by the plurality of ribs 530 and the protrusions 525.

[0083] In at least one exemplary embodiment, the first fluid passage 800 blocks or substantially blocks liquid and / or solid particles (such as dust) from entering the vent 215, so the vent is not blocked. For example, if liquid and / or solid particles accumulate at or within the vent 215, the vent 215 may become blocked and hinder the flow of air into and out of the electronic unit 100. Such blockage may create pressure, such as a vacuum, in the electronic unit 100, which may cause the electronic unit 100 to malfunction.

[0084] refer to Figure 8B , the inner surface of the third side wall 515 of the cover 205, the second side 510 of the top wall 500 of the cover 205, the outer surface of the second side wall 415, the top surface of the support wall 410, and the inner surface of the first side wall 405 define at least a portion of the second fluid passage 805. The second fluid passage 805 can be an air passage in fluid communication with the electronic unit 100. For example, the second fluid passage 805 can be configured to guide air from the surrounding environment through the vent 215 and into the electronic unit 100. The second fluid passage 805 defines a maze that air can enter and pass through, but liquids and / or solid particles cannot enter. For example, liquids and / or solid particles can fall into the filter system 105, for example, through the first fluid passage 800, before reaching the vent 215.

[0085] In at least one exemplary embodiment, the second fluid passage 805 directs air through the gap 700, the compartment 705, and the side recess 435 toward the vent 215. Air can enter the vent 215 through the side opening 620, pass through the space 615 and the channel 625, and enter the electronic unit 100 through the cavity 810. As described above, the vent 215 can include a membrane filter configured to prevent liquid and / or solid particles from entering the channel 625 and / or the electronic unit 100. For example, at least a portion of the bottom 605 of the vent 215 can include a membrane filter. In other exemplary embodiments, the membrane filter can be within the channel 625 and / or the cavity 810. In yet other exemplary embodiments, the membrane filter can be within the filter device 210, such as Figure 7B As shown, within the filter device 210. For example, the membrane filter can be located within the cavity 238 and / or coupled to the inner surface of the base 200 or the cover 205. In such an exemplary embodiment, the membrane filter can replace the vent 215.

[0086] In at least one exemplary embodiment, the second fluid passage 805 can also flow in the reverse direction. For example, air can be exhausted from the electronic unit 100 through the vent 215 and filter device 210 of the filter system 105. This allows the electronic unit 100 to "breathe", so that air can enter and exit the electronic unit 100.

The at least one protrusion 905 can be a cylindrical or substantially cylindrical protrusion surrounding the cavity 910. In other exemplary embodiments, the at least one protrusion 905 can include a first protrusion adjacent to the cavity 910 and a second protrusion opposite the first protrusion and adjacent to the cavity 910.

[0089] In at least one exemplary embodiment, cavity 910 is configured to accommodate a filter (e.g., as described above with reference to Figure 3 and 6A -8B) at least a portion of the vent 215 discussed above. In at least one exemplary embodiment, at least one protrusion 905 defines a recessed space 915 adjacent to the cavity 910. The perimeter, width, or diameter of the recessed space 915 may be greater than the perimeter, width, or diameter of the cavity 910. The cavity 910 may be configured to accommodate the first portion 245 of the vent 215, and the recessed space 915 may be configured to accommodate the second portion 250 of the vent 215. For example, the second portion 250 of the vent 215 may be located within the recessed space 915 such that the bottom surface of the bottom 605 contacts the surface of the electronic unit 900 surrounding the cavity 910, and the top surface of the top 600 of the vent 215 is flush with the outer surface of the at least one protrusion 905.

[0090] In at least one exemplary embodiment, the cover 920 is coupled to at least one protrusion 905. The cover includes a top wall 925 and a side wall 930 extending from a perimeter of the top wall 925. The side wall 930 can be configured to couple the cover 920 to the at least one protrusion 905.

For example, the at least one engagement member 935 can extend from an end of the side wall 930 perpendicular to the side wall 930 and parallel to the top wall 925. The at least one engagement member 935 can be configured to engage an exterior of the at least one protrusion 905, such as with a snap fit or other engagement mechanism, to secure the cover 920 to the electronic unit 900. The at least one engagement member 935 can be a single cylindrical member extending around the perimeter of the side wall 930. In other exemplary embodiments, the at least one engagement member 935 can be a plurality of discrete members extending from the perimeter of the side wall 930.

[0091] In at least one exemplary embodiment, at least one protrusion 940 extends from an inner surface of a top wall 925 of the cover 920. The at least one protrusion 940 is configured to extend toward the vent 215 and the electronics unit 900 when the cover 920 is coupled to the electronics unit 900. The cover also defines at least one recess 945 adjacent to the at least one protrusion 940.

[0092] In at least one exemplary embodiment, the filtration system 903 defines at least two fluid pathways. For example, the filtration system 903 defines a first fluid pathway, as described above with reference to Fig. 8A The first fluid passage 800 described above is configured to guide liquid and / or solid particles entering the filter system 903 away from the vent 215 and out of the filter system 903. The first fluid passage can be defined by the inner surface of the side wall 930, the outer surface of the at least one protrusion 905, and the inner surface of the top wall 925 of the cover 920. The liquid and / or solid particles can be guided downward along the inner surface of the top wall 925, along the at least one protrusion 940, and through the at least one recess 945 by gravity. Since the liquid and / or solid particles are guided along the inner surface of the cover 920, the liquid and / or solid particles can be prevented from entering the electronic unit 900 through the vent 215. The liquid and / or solid particles can be discharged through the bottom of the cover 920.

[0093] In at least one exemplary embodiment, the filtration system 903 defines a second fluid path, similar to the one described above with reference to Figure 8B The second fluid passage 805 described above is configured to allow air to enter and exit the electronic unit 900. The second fluid passage can be defined by the inner surface of the side wall 930, the outer surface of the at least one protrusion 905, at least a portion of the inner surface of the top wall 925 of the cover 920, and the recessed space 915. The air can flow in and out of the electronic unit 900 as described above. Figure 8B In a similar or similar manner as described, air enters and exits vent 215 and electronics unit 900 via recessed space 915.
