Abstract: Techniques for selective video conference segmentation are described and are implementable in a video conference setting. The described implementations enable control over segments of video content that are viewable by a given participant in a video conference. For instance, segments of video content are generated that represent spatial portions of video content captured by a host device. The segments can be configured in a variety of ways for inclusion in one or more video streams. The video streams can be communicated to different participants within the video conference, for instance based on a status of a given participant, thus providing different fields of view to different participants.

Abstract: This invention is a device with an expandable light-emitting display which is worn on a persons' wrist and/or lower arm. The expandable display can be a flexible display which can be rolled and then expanded by unrolling it out from a housing. In an example, the flexibility of the expandable second display can be adjusted. The second display can be made flexible so that is can be rolled around a roller, but can also be made rigid for use as a touch screen in an expanded state.

At least a portion of the plurality of calendar events are scheduled using one or more completed candidate calendars generated from the queuing.

Abstract: Aspects described herein may allow for auto-locating a user in a parking lot and/or automatically directing a user to recommended inventory. For example, a customer may capture an image of a vehicle, or a marker associated with a vehicle, in a parking lot. The image may be processed locally or at a server. A vehicle may be identified based on analysis of the image. Further, information regarding the user may be processed to determine another vehicle appropriate for a recommendation. For example, a prompt on a mobile device may suggest a popular model similar to the vehicle being viewed. The system may then provide directions (e.g., augmented reality directions) to the user to direct the user to the vehicle.
