    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.

  • Patent number: 11720173
    Abstract: Aspects of the present disclosure are directed to a multi-sensor don/doff detection system for an artificial reality device headset. The multi-sensor don/doff detection system can use a combination of a proximity sensor, an inertial measurement unit (IMU), and an eye tracking/face tracking (ET/FT) unit to make these determinations. However, when both the ET/FT system and proximity sensor system are active, they can have system coexistence issues. Thus, only one of these systems can be used simultaneously. The multi-sensor don/doff detection system can more accurately identify don events by using input from the proximity sensor and the IMU. The multi-sensor don/doff detection system can also more accurately identify doff events by using input from the IMU and either A) the proximity sensor when the ET/FT system is disabled or B) the ET/FT system when the ET/FT system is enabled.

  • Patent number: 11687132
    Abstract: A crossflow air deflector part for directing airflow includes a front central spine, a first arcuate wall extending from the spine to a first back lateral edge of the airflow deflector, and a second arcuate wall extending from the spine to a second back lateral edge of the airflow deflector opposing the first back lateral edge. Such an airflow deflector can be implemented into a storage server, positioned between a laterally adjacent pair of data storage device (DSD) chambers and a pair of vertically stacked fans, such that the crossflow air deflector functions to direct airflow from one of the lateral DSD chambers into the lower fan and to direct airflow from the other lateral DSD chamber into the upper fan. Independent airflow control for each DSD chamber and each corresponding DSD is thereby provided.

  • Patent number: 11678461
    Abstract: A fan tray system includes a fan tray base that couples to a chassis and that includes fan system connector(s) for connecting to a fan system. A fan tray side wall includes fan system guide member(s) that align the fan system for connection to the fan system connector(s), and is connected to the fan tray base by a moveable coupling that allows relative movement between the fan tray side wall and the fan tray base. That relative movement allows the fan tray side wall to be positioned in a first orientation when the fan tray base is coupled to the chassis such that the fan tray side wall is positioned adjacent a chassis wall of the chassis and impedes access component(s) in the chassis. That relative movement also allows the fan tray side wall to be moved to a second orientation that allows access to the component(s) in the chassis.

  • Patent number: 11661950
    Abstract: A diagnostic system includes a fan control circuit coupled to an electric fan and a microcontroller, and a sense line coupled to the fan control circuit and the microcontroller. The fan control circuit outputs a fan command sense signal at a duty cycle through the sense line to the microcontroller. A tachometer generates a tachometer signal at a frequency indicative of the rotational speed of the electric fan. A fan tachometer circuit receives the tachometer signal and outputs the tachometer sense signal at a frequency to the microcontroller in response to the tachometer signal. The microcontroller sets a second diagnostic flag to an error value indicating that the sense line has impaired operation if the frequency of the tachometer sense signal is within a desired frequency range, and a first diagnostic flag is equal to a first error value.
