Abstract: One disclosed example method includes a video conference provider establishing a main meeting of a video conference and multiple associated sub-meetings at the request of a host client device associated with a host of the meeting. The method further includes the video conference provider determining that a self-selection mode for the sub-meetings is enabled and transmitting notifications to participant client devices associated with the participants of the meeting. Each notification identifies a list of sub-meetings from which a participant can select a sub-meeting to join. The method further includes the video conference provider receiving and forwarding a request from a participant client device to connect to a selected sub-meeting, and receiving an automatic approval from the host client device. The video conference provider further connects the participant client device to the selected sub-meeting.

Abstract: A first product may be provided that comprises a substrate having a first surface, a first side, and a first edge where the first surface meets the first side; and a device disposed over the substrate, the device having a second side, where at least a first portion of the second side is disposed within 3 mm from the first edge of the substrate. The first product may further comprise a first barrier film that covers at least a portion of the first edge of the substrate, at least a portion of the first side of the substrate, and at least the first portion of the second side of the device.

Abstract: One example method for sharing content across videoconferencing sub-meetings includes establishing a videoconferencing session including a main meeting and a first sub-meeting, transmitting, from a first client, a content to be displayed over a data stream in the main meeting, transmitting, from a second client, a request to subscribe to the data stream over which the content is transmitted, and responsive to the request to subscribe to the data stream, receiving the content to be displayed in the first sub-meeting simultaneously with the content displayed in the main meeting.
