Abstract: Disclosed herein are related to devices and methods for communication. In one aspect, a device includes a first processor and a second processor. The first processor may be configured to generate a first set of packets associated with an application data unit in a first layer corresponding to content data. Each packet of the first set of packets may include a flag indicative of an association with the application data unit. The second processor may be configured to generate a second set of one or more packets in a second layer for transmission, in response to determining that the first set of packets is associated with the application data unit according to flags of the first set of packets. The second processor may be configured to schedule to transmit the second set of one or more packets in the second layer within a defined time period.

Abstract: Methods, apparatuses, systems, and computer readable media for managing a camera system. The camera system comprises at least a first camera and a second camera. In the method, a first position and a second position for a first object and a second object are obtained from the first and second cameras, respectively. The first and second objects are used for calibrating the camera system. After a movement of the first and second objects, a third position and a fourth position for the first and second objects are obtained from the first and second cameras, respectively. Here, a relative object position between the first and second objects remains unchanged during the movement. A relative camera position between the first and second cameras is determined based on the first, second, third, and fourth positions.

Abstract: Disclosed are methods and systems to facilitate automatic distribution of communications. In particular, a server may maintain data that indicates at least one registered subject-matter interest respectively for each of a plurality of users. Further, the server may receive a communication from a source user. The source user may be served by a particular base station. In response to receiving the communication, the server may identify one or more target users based on each target user (i) having at least one registered subject-matter interest that matches at least one subject-matter interest of the source user and (ii) being served either by the same particular base station that serves the source user or by a base station adjacent to the particular base station that serves the source user. The server may forward the communication to each identified target user.
