Abstract: The present invention provides a method for evaluating the properties of hydrogen to improve the safety of hydrogen fuel, and provides a method for selecting proper odorants for hydrogen. Odorized hydrogen containing suitable odorants in appropriate concentrations with hydrogen are also provided.

Abstract: A system and method of enhancing the viewing experience of at least one viewer of a broadcast presentation by displaying, in a background layer of a single-window, layered display, a broadcast presentation, and for displaying, in at least a second layer of the layered display, at least one overlay having a substantially transparent background and having at least one overlay having a plurality of user-selectable multi-media tools, for manipulating the overlay by adding user-prepared enhancements to be viewed in connection with the broadcast presentation. The system may also transmit the user-prepared enhancements to all of viewers of the broadcast presentation over a computer network, where they are displayed on display devices associated with each viewer of the broadcast presentation.

Abstract: Methods and systems for transmitting user part messages between signaling system seven (SS7) signaling points over an internet protocol (IP) network include receiving, at a signal transfer point, a first SS7 user part message. The first SS7 user part message can be received from a first SS7 signaling point, such as a service switching point (SSP). The first SS7 signaling point is encapsulated in a first IP packet. The first IP packet is transmitted to a second SS7 signaling point over an IP network.

Abstract: An end office support (EOS) routing node implements MTP layers 1-3 on behalf of one or more remote applications that share the true point code of the EOS routing node. Implementing MTP layers 1-3 includes receiving messages addressed to the true point code, determining whether the messages are contain application level information of interest to a remote application, and forwarding the application level information to the remote application. Messages may be routed internally within the EOS routing node using an internal point code used to uniquely identify the remote application within the EOS routing node. The EOS routing node may also perform network management functions on behalf of one or more remote applications.

Abstract: In a peer-to-peer multi-media communication network, a system for controlling a broadcast viewing experience of one user (second user) by a first user. Each user has access to a user workstation including at least an input device and a display device. The second user's workstation includes a storage device for storing at least user input for controlling a display on a display device coupled to the second user workstation. The first user workstation includes a dynamic display controller, responsive to an input device on the first user workstation, for receiving input from the first user workstation and for transmitting the user input to at least the second user workstation. The user input received by the second user workstation controls the display on the second user workstation display device.

Abstract: A normalizing signaling gateway (NSG) routing node receives a first signaling message formatted according to a first variant of a common or standard signaling protocol, such as ISUP, and creates a second signaling message based on the first message. The second signaling message includes a normalized component and a variant component. The second signaling message may then be routed to a second NSG routing node or to a media gateway controller. Because the NSG routing node converts messages to and from variants of a standard signaling protocol, the media gateway controller is not required to support all of the variants of the standard signaling protocol, and its complexity is reduced.

Abstract: A system and method of displaying interactive content relevant to a broadcast presentation on a viewer display associated with a viewer device. The method begins with the receipt, at said viewer device, of a broadcast presentation from a broadcast presentation provider. Next, the viewer device receives relevant interactive content from a source of interactive content, filtered and characterized for a specific user. This additional content is bound to the broadcast content only by nature of a relevancy mapping. As such, it may be presented to the user without the broadcast content providers direct assistance. The viewer device merges the broadcast presentation and the relevant interactive content and displays both the broadcast presentation and the relevant interactive content on a viewer display. Preferably, the viewer device accesses the source of relevant interactive content over a computer network, such as the Internet.

Abstract: Disclosed is a communications network element that is capable of routing signaling messages and includes a dynamic routing key registration feature which allows Internet protocol (IP) nodes to automatically register/de-register and subsequently direct traffic towards or away from themselves without the need for manual operator intervention. A signaling gateway routing node includes a self-registering data communication module (sDCM) that is adapted to receive and process dynamic routing key registration messages from associated IP nodes. Such dynamic routing key registration messages may include information that is used to register a new routing key association with a TCP/IP connection, de-register an existing routing key association with the TCP/IP connection, or modify routing key information associated with the TCP/IP connection.

Abstract: Seamless transport of messages is provided between SS7 network elements and Internet Protocol (IP) network elements using an STP as an intermediary. Thus, messages may be routed between a first SP and a second SP via an STP using IP. Messages may be routed between an SP and an IP node via an STP using IP. Messages also may be routed between a first IP node and a second IP node via an STP using IP. Thus, the STP can be used as a vehicle for message transport among nodes of an SS7 network, among nodes of an IP network and between SS7 and IP networks. SS7 messages are bidirectionally communicated between an STP and at least one other SP of an SS7 network using IP, preferably TCP/IP. Preferably, SS7 messages are bidirectionally communicated between an STP and at least one SCP using IP.

Abstract: A tank for receiving a carbon- and hydrogen-containing fluid for supplying a fuel cell system with an operating medium has an inlet and an outlet for the fluid and at least one straining means for the fluid arranged between the inlet and the outlet.
