  • Patent number: 8045694
    Abstract: An interface for use in a telephone communication system provides for connection of a telephone switch to an IP network, allowing data signals between the telephone switch and a VMS to be transmitted by the IP network. In addition to transmission of the signals over an IP network, the interface can be configured to provide additional functionality including translation of the message protocol; connection of the interface to a network operations center; verification of message accuracy and completeness; acknowledgment of the receipt of a message; activation/deactivation of a message waiting indicator; connection to an SS7 network; back-up transmission between the IP network and the switch; and proxy/redirect of voice signals.

  • Publication number: 20090050143
    Abstract: A container, such as a metered dose inhaler, suitable for use with a propellant-based medicinal formulation, the container comprising one or more treated metal surfaces that come into contact with the medicinal formulation, wherein the one or more treated metal surfaces are characterized by an organic surface treatment compound covalently bonded to the metal surface through a reactive head group selected from either phosphonic acid or carboxylic acid and wherein the organic surface treatment compound is further characterized by an exposed, substantially non-reactive tail group disposed away from the metal surface. Also, metered dose inhaler canisters and valves with treated surfaces.
