Abstract: A virtual token represents an item, and includes embedded data defining rules and/or capabilities which apply to the use of the item. A virtual token may include graphical image data which is used to generate a display on a computer, whereby selection of the display allows the item represented by the virtual token to be used. A virtual token may contain instructions for sending access requests to a location on a communications network. A system for handling virtual tokens includes a clearing and routing house for routing token access requests, authenticating and generating tokens, and maintaining container structures for tokens. The system also includes connectors installed in a communications network for creating, controlling and managing items represented by tokens, and device clients for executing token components that issue access requests to the clearing and routing house.

Abstract: Embodiments of the present invention provide for broadcast pause and resume for enhanced television. In some embodiments, software key frames identifying a state of a browser at a plurality of points in time may be used for synchronizing a series of graphics to a video stream. Other embodiments may be described and claimed.

Abstract: A cooling media pack is provided which is adapted to be used in either film-fill or splash-fill cooling towers. The pack is formed of a plurality of alternating sheets, each of which has an undulating shape, thereby defining a series of ridges in each sheet. Each of the ridges has a peak and trough. The sheets are oriented such that the troughs of one sheet are adjacent the peaks on an adjacent sheet. Further, the ridges of every other sheet are oriented at a first angle with respect to the horizontal and the ridges of the remaining sheets are oriented at a second angle with respect to the horizontal. Each of the sheets includes a plurality of voids which are designed to enhance the efficiency of the cooling media pack, inhibit fouling, and inhibit the formation and/or accumulation of bacteria.

Abstract: A system communicates video information including television content associated with a plurality of channels and ancillary information. Information may be transmitted with the ancillary information that is indicative of the type of content included in the ancillary information. This provides the user, in one embodiment of the present invention, with a visual indication of the type of information that accompanies television content. This helps the user to decide whether the user wishes to view the ancillary information and provides the opportunity to select that enhancement for viewing.
