  • Patent number: 8060416
    Abstract: The present invention relates to a method and system for providing advertising inventory information. More specifically, the present invention relates to a method and system for providing advertising inventory information in response to demographic inquiries. In an exemplary embodiment, a server responds to a demographic query. Based on the query, the server queries an advertising inventory database and a contract database to retrieve relevant information. Using the relevant information, the total inventory and the total sold inventory are obtained. Using the now obtained total inventory and the total sold inventory information, the server then provides an estimation of the total available inventory matching the query.

  • Publication number: 20070114765
    Abstract: This invention relates to a foldable wheelbarrow and a foldable hand cart. Both comprise a wheel mounting assembly, a leg assembly rotatably connected to the wheel mounting assembly, one or more wheels rotatably connected to the wheel mounting assembly, a collapsible container connected to the wheel mounting and leg assemblies, and at least one support member rotatably connected to both the wheel mounting and leg assemblies and serving to maintain the wheelbarrow in an erected position. The handle members have a pair of handles and a kicker, the kicker has a pair of interconnected longitudinally-extending portions that are each rotatably connected to an associated rear handle segment thereby enabling the handle members to rotate between erected and folded position.

  • Publication number: 20060234107
    Abstract: A fuel cell plate comprises a basic plate generally adaptable to be used, for a flow of a fluid, as a cathode. The basic plate has essentially a trapezoidal top view, delimitated by a pair of longitudinal margins, and a long and short transversal margins and is provided with inlet and outlet apertures, the former being disposed parallel and close to the long transversal margin, while the latter is disposed close to the short transversal margin. The basic plate also incorporates a continuous wall, spaced from the pair of longitudinal margins and the long and short transversal margins, and extending upwardly from a top of the basic plate, the continuous wall circumscribing a flow field divided into a multiplicity of channels. Cross-sections of the flow field of the basic plate, open to the flow of fluid entering through the inlet apertures, then flowing throughout the channels and exiting through the outlet apertures, continuously diminish, so that, accordingly, velocities of the fluid continuously increase.

  • Publication number: 20060047379
    Abstract: A railcar asset management system proactively issues an alert or task when a pre-determined event occurs. The system may receive information regarding the location and status of a railcar from sensors on the railcar that may include a telematics sensing unit. A database in the railway telematics system stores the data regarding the railcar location and status information. The system determines whether an event has occurred and issues the proactive alerts and/or task. The system may communicate the proactive alert via e-mail, paging, PDAs or by cell phone and may provide interactive preconfigured web pages.
