    Abstract: A head-mounted device can effectively manage heat while also managing noise output in a manner that reduces the user's perception thereof. For example, a support member extending across a flow channel can provide multiple sections with different profiles and/or cross-sectional dimensions within the flow channel. Each of the profiles and/or cross-sectional dimensions can generate tonal noises at different frequencies, so that the tonal noises generated are distributed across multiple frequencies to mask such tonal noises among broadband noises that are generated by the head-mounted device. Such a support member can be moveably positioned within the flow channel and rigidly coupled to other components of the head-mounted device. Such a support member can also be used to draw heat away from other components of the head-mounted device to be dissipated by the flow of air within the flow channel.

    Abstract: A wearable display system includes a housing, a display module positioned within the housing and including a lens and a display panel, and a seal extending between the housing and the display module. The seal is configured to allow relative movement between the lens and the display panel to adjust focus of the display panel. In one aspect, the seal includes first and second segments with generally linear configurations and a third segment with an arcuate configuration that is positioned between the first and second segments. In another aspect, the seal includes a first portion with an arcuate configuration and a second portion with a linear configuration and a bellows portion. In another aspect, the seal includes corrugations to facilitate controlled deformation of the seal during relative movement of the display module.

    Abstract: A head-mounted device includes a housing configured to be worn on a head of a user. The housing includes an inlet port and an outlet port. An air circulation device is mounted to the housing and configured to produce a flow of air through an air flow path in the housing that extends from the inlet port to the outlet port. A display assembly is mounted to the housing and has a surface in the air flow path of the housing. An air deflector mounted to the surface of the display assembly and configured to reduce a turbulence of the flow of air through the air flow path.

    Abstract: A head-mounted device may have a display with first and second pixel arrays that display content for a user. A head-mounted support structure in the device supports the pixel arrays on the head of the user. A left positioner may be used to position a left lens module that includes a left lens and the first pixel array. A right positioner may be used to position a right lens module that includes a right lens and the second pixel array. Sensing circuitry such as proximity sensing circuitry may be used to detect relative positions between the left and right lens modules and facing surfaces of a user's nose while the user is wearing the head-mounted support structure. Control circuitry may adjust the positions of the left and right lens modules using interpupillary distance information for the user and using information from the sensing circuitry.
