  • Publication number: 20240068484
    Abstract: A head-mountable device can include a fan that effectively manages heat while also mitigating the intrusion of particles and other debris. Fans can include a protrusion that creates a tortuous pathway to direct incoming particles away from sensitive regions. Fans can include openings to allow particles to exit the fan enclosure and avoid interaction with the impeller. Fans can include a variable spacing between the impeller and the base plate to avoid collection of particles. Fans can include an adhesive pad that collects and retains particles at a location that does not interfere with rotation of the impeller.

  • Publication number: 20240027778
    Abstract: A head-mounted device may have a head-mounted housing. The housing may include a chassis with left and right openings that overlap respective left and right optical modules that present images eye boxes. Each optical module may have a lens and display that presents an image through the lens. The chassis may have an inner frame and outer frame. A middle portion of the chassis may form a stiffened nose bridge structure. Components in the housing such as a display, a fan housing, a heat sink layer, optical module guide rods, and a rear cover may span the width of the housing and may be attached to edge portions of the chassis, thereby forming a box-shaped structure that provides rigidity and helps prevent housing deformation.

  • Patent number: 11716829
    Abstract: A head-mountable device can provide a cooling module that effectively manages heat while also minimizing noise, vibration, leakage, power consumption, size, and weight. To dissipate heat, the cooling module with a fan can be operated to move air through a chamber within the head-mountable device. An integrated heat sink can provide heat dissipation properties by drawing heat away from heat-generating components and into the chamber. The integrated heat sink can include a base plate that defines at least a portion of the chamber in which the blades of the fan are positioned. The integrated heat sink can further include fins between the chamber and an outlet. The fins can be integrated with the base plate to maximize heat dissipation and reduce the number of interfaces between separate parts.

  • Patent number: 11340670
    Abstract: A display system, such as a wearable display device, includes a system housing including a cavity having a linear axis extending generally in parallel with first and second side walls enclosing the cavity and a display stack enclosed within the cavity and movable along the linear axis. The display stack includes a display panel and a support chassis configured to support a first side of the display panel and thermally couple the display panel to the first side wall to facilitate heat transfer from the display panel, across the support chassis, and to the system housing The display stack includes a heat sink configured for support by a second side of the display panel and to thermally couple the display panel to the second side wall to facilitate heat transfer from the display panel, across the heat sink, and to the system housing.

  • Patent number: 11218824
    Abstract: A head-mounted device can effectively manage heat while also managing noise output levels in a manner that preserves the user's desired experience with the head-mounted device. The head-mounted device can manage sound levels of a cooling system based on detected a sound level of ambient noise in a vicinity of the head-mounted device. For example, the head-mounted device can operate a fan at a speed that produces noise at a sound level that is low enough to be masked by the ambient noise perceived by the user. By further example, the sound level of a cooling system can be based on a sound level of a speaker of the head-mounted device providing audio to the user. By further example, other operational parameters of a cooling system can be controlled to manage noise at a sound level that is sufficiently low.

  • Publication number: 20210376534
    Abstract: High-speed connectors that simplify connectivity between electronic devices, are simple to use, and are readily manufactured. One example can simplify connectivity by including contacts for power, data, and one or more RF signals into a single connector. One example provides a connector receptacle having a tongue supporting contacts for data and power. A ground contact can encircle the tongue and a shield can be around the tongue, contacts, and ground contact. An RF contact can be positioned between the ground contact and the shield, such that the ground contact and shield provide RF shielding for the RF contact.
