Abstract: A wireless local area network (WLAN) access point (AP) transmits a ready-to-send (RTS) frame. In response to the transmitted RTS frame and during a transmission opportunity (TXOP), a clear-to-send (CTS) frame from a first station is received. The WLAN AP further transmits at least one data frame in response to the received CTS frame and in response to the transmitted at least one data frame, an acknowledgement from the first station. The WLAN AP further transmits, in response to the received acknowledgement signal, a first medium access control (MAC) frame which is received by a second station, and the WLAN AP receives, in response to the transmitted first MAC frame and during the TXOP, a second MAC frame from the second station.

Abstract: Digital image data including discrete photographic images of a variety of different subjects, times, and so forth, are collected and analyzed to identify specific features in the photographs. In an embodiment of the invention, distinctive markers are distributed to aid in the identification of particular subject matter. Facial recognition may also be employed. The digital image data is maintained in a database and quarried in response to search requests. The search requests include criteria specifying any feature category or other identifying information, such as date, time, and location that each photograph was taken, associated with each photograph. Candidate images are provided for review by requesters, who may select desired images for purchase or downloading.

Abstract: A system and method for dynamically retrieving, manipulating, updating, creating, and displaying data from sources of Extensible Markup Language (XML) documents. The program memory comprises system-user entered data definitions and business rules. The system imports XML document data into the system data definitions, processes the data using the business rules definitions and exports XML documents. The system can automatically create XML document formats from its data definitions and can automatically create its data definitions from XML document formats. The system-user can also define the mapping between XML document formats and the system data definitions. The system data definition is the combination of a Relational data model, an Object data model, and an XML data model.

Abstract: Embodiments of dual mode communication systems and methods are disclosed. On system embodiment, among others, comprises logic configured to perform spatial multiplexing and expanded bandwidth signaling to data.

Abstract: In a system for providing access control management to electronic data, techniques to secure the electronic data and keep the electronic data secured at all times are disclosed. According to one embodiment, a secured file or secured document includes two parts: an attachment, referred to as a header, and an encrypted document or data portion. The header includes security information that points to or includes the access rules and a file key. The access rules facilitate restrictive access to the secured document and essentially determine who/when/how/where the secured document can be accessed. The file key is used to encrypt/decrypt the encrypted data portion. Only those who have the proper access privileges are permitted to retrieve the file key to encrypt/decrypt the encrypted data portion.

Abstract: The present invention relates to a method for utilizing a mobile station for the transmission of authorization information requiring verification in a telecommunication network comprising the mobile station. In the method, the information to be verified is transmitted to the mobile station, the authorization information transmitted is presented on the display of the mobile station, the authorization information presented is read from the display of the mobile station, and the authenticity of the authorization information thus read is verified. According to the invention, the authorization information is sent in a form comprising information to be presented in a graphic form, and the authorization information is presented on the display of the mobile station using a user-independent function of the mobile station in question for the presentation of graphic information.

Abstract: A computer system includes a server having a memory connected thereto. The server is adapted to be connected to a network to permit remote storage and retrieval of data files from the memory. A file identification application is operative with the server to identify errant files stored in the memory. The file identification application provides the functions of: (1) selecting a file stored in said memory; (2) generating a unique checksum corresponding to the stored fire; (3) comparing said unique checksum to each of a plurality of previously generated checksums, wherein the plurality of previously generated checksums correspond to known errant files; and (4) marking the file for deletion from the memory if the unique checksum matches one of the plurality of previously generated checksums.

The external access server is also configured to permit file exchange between the internal users and the external users via the server.

Abstract: A method of arranging the transmission of packet data in a system comprising a mobile terminal, a wireless local network and a mobile network that includes end-to-end service related parameters that are signalled via a separate signalling element. A resource authorization identifier is transmitted to the mobile network via the local network. Authorization is requested from the signalling element on the basis of the resource authorization identifier. A tunnel between the mobile terminal and the mobile network is bound to the end-to-end data flow of the mobile terminal on the basis of an authorization from the signalling element and tunnel identification information identifying the tunnel.
