Abstract: To overcome potential problems associated with overflowing counters/timers, embodiments of the present invention include a ping timer and a pong timer offset from each other, and a time checker that accesses at any one timer either the ping timer or the pong timer to determine whether a time interval has passed. Upon passage of the time interval, the time checker switches access from the ping timer to the pong timer before the ping timer reaches an overflow state, thereby avoiding problems associated with counter/timer overflow.

Abstract: A system and method for controlling access to digital content based on proximity and location of a user device. A user device connects to a local network and an audio transmission including a perpetually rolling key is transmitted within a geo-fence in the local area. The user device hears the audio transmission and uses the key to authenticate to a content server over the network. Once authenticated, the user device may then stream content from the content server. In order to terminate access to the content when the user device leaves the geo-fence, the content server may require the key to be retransmitted from the user device at regular intervals to re-authenticate the user device. Other factors such as radio fingerprints from the user device may also be used instead of or in addition to the audio to verify the user device's presence within the geo-fence.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A request for content is received from a user device. A content item is identified for delivery to the user device responsive to the request. A location of the user device is determined. A threshold distance is determined that a user is likely willing to travel when visiting a physical location associated with the content item or content sponsor. A bounding region associated with the location of the user device is identified. Location extensions are identified that are associated with the content item. A determination is made when one of the location extensions is included in the bounding region and when a distance between the location extension and a current location of the user is less than the determined threshold distance. The content item is augmented with the one location extension.
