  • Patent number: 12175610
    Abstract: A method for aligning the positions and orientations of a real object and a virtual object in real space, the virtual object corresponding to a virtual replica of the real object, the method comprising visualizing at least one alignment feature superimposed on or replacing a representation of the virtual object in a field of view containing the real object, wherein the alignment feature is indicative of a position and orientation of the virtual object in real space, and wherein the at least one alignment feature complements a shape and/or surface pattern of the real object, such that the alignment feature and the real object form a composite object with complementing patterns and/or shapes in the field of view, when the real object and the virtual object are aligned.

  • Patent number: 12081599
    Abstract: Systems and methods for providing pronunciation services for video conferencing are described. A method includes receiving, by a video conference provider, an audio stream of a pronunciation of one or more words. The video conference provider may associate the audio stream of the pronunciation with a user of a first client device, in which the first client device is configured to join a video conference hosted by a video conference provider, the video conference having a plurality of participants using a plurality of client devices. The video conference provider then receives, from a second client device, a first indication to play back the pronunciation. Responsive to the first indication, the video conference may provide, to the second client device, the audio stream of the pronunciation. The video conference provider then outputs instructions to cause the second client device to play back the audio stream of the pronunciation.

  • Patent number: 11082238
    Abstract: A method for network authentication of wireless devices at a gateway is provided that includes scanning a wireless network by the gateway to discover unjoined wireless devices, joining a discovered wireless device to the gateway using a non-internet protocol implemented by the wireless device, wherein the joining results in an encrypted connection between the gateway and the wireless device, and authenticating the discovered wireless device to the gateway via the encrypted connection, wherein authentication is performed according to an authentication protocol of a network protocol management layer of the gateway.

  • Patent number: 10992482
    Abstract: Methods, systems, and apparatus, including computer-readable media, for verified boot and key rotation. In some implementations, a device extracts a public key from a secure data storage area of the device. The device extracts a first certificate for an intermediate key and a second certificate for a signing key, the first certificate and the second certificate being extracted from a system image. The device verifies a signature of the first certificate using the public key. After verifying the signature of the first certificate, the device verifies the second certificate using a public key in the first certificate. In response to verifying the second certificate, the device loads the system image during a boot process of the device.
