Patent number: 12081599Abstract: 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.Type: GrantFiled: April 14, 2023Date of Patent: September 3, 2024Assignee: Zoom Video Communications, Inc.Inventor: Alejandro Martin Paiuk

Patent number: 10992482Abstract: 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.Type: GrantFiled: December 14, 2017Date of Patent: April 27, 2021Assignee: Google LLCInventors: Alejandro Martin Deymonnaz, Darren David Krahn, David Zeuthen
