Abstract: Techniques are described for maintaining contextual data to support content-related actions. In an example, a system stories second content at a source. The source is associated with first content. The system sends, to a device, an object that indicates the first content. From the device at a first time, the system receives first data indicating a first request for the second content and including source information that indicates the source. From the device at a second time, the system receives second data indicating a second request for the second content, the second data including the source information, the first data and the second data received at a frequency indicated by the object. The system determines that the requests are associated with the first content based on the source information included in the received data, and stores third data indicating a presentation of the first content by the device.

Abstract: A method and system for communication with a mobile platform is provided. An antenna system coupled to a transmitter for use in providing a communication channel to a mobile user includes a first linear transmit array of radiating horns, a second linear transmit array of radiating horns, and at least one reflector coupled to at least one of the first linear transmit array and the second linear transmit array, the at least one reflector configured to reflect illumination from the first and second linear transmit arrays to form a communication channel for the mobile user.

Abstract: An antenna array system for directing and steering an antenna beam is described in accordance with the present invention. The antenna array system may include a feed waveguide having a feed waveguide length, at least two directional couplers in signal communication with the feed waveguide, at least two pairs of planar coupling slots along the feed waveguide length, and at least two horn antennas.
