Abstract

An example MR headset is provided. The MR headset includes a two-part housing configured to house electronic and mechanical components used to present MR content, the two-part housing including a first part of the two-part housing and a second part of the two-part housing. And the MR headset includes a channel defined by a first perimeter of the first part of the two-part housing and a second perimeter of the second part of the two-part housing. The channel is configured to guide perspiration along the first perimeter of the first part or the second perimeter of the second part away from the electronic and mechanical components housed in the two-part housing.

First claim

What is claimed is:

1 . A two-part housing of a mixed-reality (MR) headset, comprising:
a first part of the two-part housing; a second part of the two-part housing; and a channel formed by coupling the first part of the two-part housing to the second part of the two-part housing, the channel defined by a first portion of a first perimeter of the first part of the two-part housing overlapping a first portion of a second perimeter of the second part of the two-part housing, wherein a second portion of the second perimeter of the second part of the two-part housing extends away from the channel, wherein:
the channel is configured to guide perspiration along the first perimeter of the first part or the second perimeter of the second part away from electronic and mechanical components housed in the two-part housing.

2 . The two-part housing of claim 1 , wherein the channel includes a set of path irregularities, each respective path irregularity configured to:
reduce a flow velocity of the perspiration being guided along the first perimeter of the first part or the second perimeter of the second part; increase a path length of the channel such that perspiration guided along the first perimeter of the first part, or the second perimeter of the second part travels a longer path before reaching an end of the channel; and/or increase a volumetric perspiration capacity of the channel.

3 . The two-part housing of claim 2 , wherein the set of path irregularities includes one or more pockets defined in the first perimeter or the second perimeter, the pockets configured to collect perspiration being guided along the channel.

4 . The two-part housing of claim 3 , wherein the one or more pockets each comprise a hydrophilic portion configured to receive perspiration guided along the channel.

5 . The two-part housing of claim 2 , wherein the set of path irregularities includes a tortuous path that deviates from a direction along the first perimeter or the second perimeter.

6 . The two-part housing of claim 1 , wherein the first portion of the first perimeter of the first part of the two-part housing comprises a first hydrophobic portion, wherein the first portion of the second perimeter of the second part of the two-part housing comprises a second hydrophobic portion adjacent to the first hydrophobic portion, the first hydrophobic portion and the second hydrophobic portion configured to repel perspiration guided along the channel.

7 . The two-part housing of claim 1 , wherein the channel is a c-channel that includes a recessed portion of a respective perimeter of the first perimeter or the second perimeter.

8 . A mixed-reality (MR) headset, comprising:
a two-part housing configured to house electronic and mechanical components used to present MR content, the two-part housing including a first part of the two-part housing and a second part of the two-part housing; and a channel formed by coupling the first part of the two-part housing to the second part of the two-part housing, the channel defined by a first portion of a first perimeter of the first part of the two-part housing overlapping a first portion of a second perimeter of the second part of the two-part housing, wherein a second portion of the second perimeter of the second part of the two-part housing extends away from the channel, wherein:
the channel is configured to guide perspiration along the first perimeter of the first part or the second perimeter of the second part away from the electronic and mechanical components housed in the two-part housing.

9 . The MR headset of claim 8 , wherein the channel includes a set of path irregularities, each respective path irregularity configured to:
reduce a flow velocity of the perspiration being guided along the first perimeter of the first part or the second perimeter of the second part; increase a path length of the channel such that perspiration guided along the first perimeter of the first part, or the second perimeter of the second part travels a longer path before reaching an end of the channel; and/or increase a volumetric perspiration capacity of the channel.

10 . The MR headset of claim 9 , wherein the set of path irregularities includes one or more pockets defined in the first perimeter or the second perimeter, the pockets configured to collect perspiration being guided along the channel.

11 . The MR headset of claim 10 , wherein the one or more pockets each comprise a hydrophilic portion configured to receive perspiration guided along the channel.

12 . The MR headset of claim 9 , wherein the set of path irregularities includes a tortuous path that deviates from a direction along the first perimeter or the second perimeter.

13 . The MR headset of claim 8 , wherein the first portion of the first perimeter of the first part of the two-part housing comprises a first hydrophobic portion, wherein the first portion of the second perimeter of the second part of the two-part housing comprises a second hydrophobic portion adjacent to the first hydrophobic portion, the first hydrophobic portion and the second hydrophobic portion configured to repel perspiration guided along the channel.

14 . A method of assembling a mixed-reality (MR) headset, comprising:
coupling a first part of a two-part housing and a second part of a two-part housing, thereby forming a channel defined by a first portion of a first perimeter of the first part of the two-part housing overlapping a first portion of a second perimeter of the second part of the two-part housing, wherein a second portion of the second perimeter of the second part of the two-part housing extends away from the channel, wherein:
the channel is configured to guide perspiration along the first perimeter of the first part or the second perimeter of the second part away from electronic and mechanical components housed in the two-part housing.

15 . The method of claim 14 , wherein the channel includes a set of path irregularities, each respective path irregularity configured to:
reduce a flow velocity of the perspiration being guided along the first perimeter of the first part or the second perimeter of the second part; increase a path length of the channel such that perspiration guided along the first perimeter of the first part, or the second perimeter of the second part travels a longer path before reaching an end of the channel; and/or increase a volumetric perspiration capacity of the channel.

16 . The method of claim 15 , wherein the set of path irregularities includes one or more pockets defined in the first perimeter or the second perimeter, the pockets configured to collect perspiration being guided along the channel.

17 . The method of claim 16 , wherein the one or more pockets each comprise a hydrophilic portion configured to receive perspiration guided along the channel.

18 . The method of claim 15 , wherein the set of path irregularities includes a tortuous path that deviates from a direction along the first perimeter or the second perimeter.

19 . The method of claim 14 , wherein the first portion of the first perimeter of the first part of the two-part housing comprises a first hydrophobic portion, wherein the first portion of the second perimeter of the second part of the two-part housing comprises a second hydrophobic portion adjacent to the first hydrophobic portion, the first hydrophobic portion and the second hydrophobic portion configured to repel perspiration guided along the channel.
