A method implemented in a computer system for controlling the delivery of data and audio/video content. The method delivers primary content to the subscriber device for viewing by a subscriber. The method also delivers secondary content to the companion device for viewing by the subscriber in parallel with the subscriber viewing the primary content, where the secondary content relates to the primary content. The method extracts attention estimation features from the primary content, and monitors the companion device to determine an interaction measurement for the subscriber viewing the secondary content on the companion device. The method calculates an attention measurement for the subscriber viewing the primary content based on the attention estimation features, and the interaction measurement, and controls the delivery of the secondary content to the companion device based on the attention measurement.

Authentication in a system includes presenting information to a user containing a partial sequence of a passcode along with distractors. The user is challenged to identify the partial sequence from among the information in order to gain access to the system.

During each node's awake period, each node multicasts the relative time or slot of their next awake period (beaconing interval) to all neighboring nodes. This enables each node to intelligently and independently schedule the time slot of its next transmission based on the beaconing intervals of the nodes it has heard from. During each active (awake) interval, a node builds statistics of the future transmission/receive times of its neighbors and uses them to determine its next transmission time. In one proposed implementation, at the end of an active interval, a node picks the time slot with the highest counter for its next transmission. In another proposed implementation, at the end of an active interval, a node picks one of the slots with a weighted probability; the weight of each slot is proportional with the value of the counter associated with the slot.
