Abstract: A system for monitoring advertisements has a security camera and sensor that are positioned to monitor an area surrounding the advertising structure with the advertisement. The camera and sensor can be controlled by a control module. The control module can activate the camera in response to receiving a signal from the sensor indicating activity in the area surrounding the advertising structure. The camera can capture images of the area surrounding the advertising structure and provide the images to the control module. The control module can then provide the images to a server for access by a user.

Abstract: A communication technique enables the efficient transmission of data through a low bandwidth and/or time delayed communication link and minimizes the idle time of the communication link by using a deferred acknowledgment of message bundles to temporally pack the communication link. The transmitting system stores messages to be transmitted in a pending message queue and applies a dynamic window to the pending message queue to define a message bundle to be sent through the slow communication link. The transmitting system requests an acknowledgment for at least one message within the bundle, but does not require an acknowledgment for every message within the bundle. Transmitted messages are temporarily stored as outstanding messages in a retransmission queue until the transmitted messages are acknowledged or until a time-out period associated with the messages has lapsed.
