An application on a server submits the message to a gateway (1) (which it sees as a service centre). The gateway performs interaction with external applications on servers such as charging and then instead of storing transaction related information associated with this message, it packages the transaction information along with the message as inter-working data. The gateway then forwards the message including the inter-working data to the service center, while requesting a delivery receipt. The service centre may generate a message-id for this transaction, but no data relating to the transaction now needs to be stored by the gateway. The gateway (1) then informs the application that it has successfully stored the message for delivery. When the message reaches a complete state in the service centre the service centre (25) sends the gateway (1) a delivery receipt including the service centre generated message-id and the inter-working data. At this point the gateway no longer needs to retrieve transaction information relating to this message (based on service centre and message-id), as the data is already present in the message. On inspection of the transaction information the gateway can determine whether the original application requested the delivery receipt, and if so, forward the receipt to the application. Dependent on the resulting state of the message and any transaction information, the gateway may interact with external servers again. At this stage the gateway (1) then generates a Call Detail Record and acknowledges receipt of the delivery receipt.

A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”

In one-tuner smart antennas, a constant amplitude representation of the antenna element wideband signal is correlated with a representation of the smart antenna output signal to give a measure of the selected channel bandpass power and desired signal power. Since only signals in the selected channel bandpass of the wideband antenna signals can be correlated with signals in the selected channel, the correlator allows only the selected channel bandpass components of the wideband antenna input signal to contribute to the correlator output. This eliminates the influence of adjacent channels/bands signals and prevents capture by strong adjacent signals. As the smart antenna adapts and reduces the selected channel bandpass interference, the measure becomes that of the desired signal power. The present invention reduces the distortion and capture of the antenna branch amplitude limiter for the weight calculation, power detection of the input power and AGC of an antenna element.

A FFAG is a particle accelerator having turning magnets with a linear field gradient for confinement and a large edge angle to compensate for acceleration. FODO cells contain focus magnets and defocus magnets that are specified by a number of parameters. A set of seven equations, called the FFAG equations relate the parameters to one another. A set of constraints, call the FFAG constraints, constrain the FFAG equations. Selecting a few parameters, such as injection momentum, extraction momentum, and drift distance reduces the number of unknown parameters to seven. Seven equations with seven unknowns can be solved to yield the values for all the parameters and to thereby fully specify a FFAG.
