Abstract:
A technique to electronically deliver a message from a sender to an intended recipient based on tracking movement of a mobile object, including obtaining a message provided by the sender, obtaining a location designated by the sender for delivery of the message, tracking a specified mobile object having a position-determining device that determines its own current position, and which transmits its then current position at preset time intervals, determining from the transmitted current position whether the specified mobile object has reached the designated location, and initiating a procedure for automatic delivery of the message electronically to the intended recipient upon the specified mobile object being determined to have reached the designated location.
Abstract:
A communications system is provided, the system being operable to provide a communications session utilising an internet protocol, such as for example IPv4, IPv6 and their extensions mobile IPv6 or IPv4. The system comprises a mobile node having an application program (410) and an operating system (420). The application program (410) is operable to provide the communications session using an internet protocol address information. The operating system (420) is operable to monitor the internet protocol address information and to inform the application program of a change of internet protocol address information. The application program is arranged to adapt the communications session in accordance with the change of internet protocol address information. As a result of the operating system informing the application program of a change of the internet protocol address information, the application program can adapt the operation of the communications session to reduce a likelihood of the communications session being affected when the IP address changes.
Abstract:
Method for optimal estimation of a propagation channel based solely on pilot symbols. A base of natural vectors is formed using the correlation matrix of the channel observed solely at the positions of the pilot symbols. Channel representation is broken down in this base. The base vectors are extended to the data symbols, which allows optimal interpolation of channel estimation to the data symbols. Application to OFDM, TDMA and CDMA systems.
Abstract:
Label switching paths in an MPLS network having plural nodes connected by IP links, each path passing through a series of network nodes and links called “elements of the path,” are protected. An element of a first path is protected by a bypass path starting from a node of the first path upstream and ending in a node of the first path downstream of the element to be protected. A certain number of resources of the network are reserved for the bypass path. An element of a second path is protected by a bypass path of the second path starting from a node of the second path upstream of the second element and ending in a node of the second path downstream of the second element. The bypass path of the second path includes at least one part of the resources reserved for the first bypass path.
Abstract:
The video component(s) of a digital audio-visual first program are switched onto the video components of a second digital, audio-visual program by (1) switching onto the video component of the second program, subsequent to the switch command and to the end of a picture of the first program, and (2) replacing, as seen in the order of transmission, each non Intra picture of the component of a second program, with a picture having coding performed independently of (a) the picture data of the replaced picture and (b) of the contents of the pictures to which it refers until the beginning of the next Intra picture of the component of the second program.
Abstract:
Input data are translated into at least one output sentence by a decoding step which sub-lexical entities represented by the input data are identified by a first model. During decoding, as the sub-lexical entities are identified and with reference to at least one second mode, various possible combinations of the sub-lexical entities are generated. Plural possible combinations of the sub-lexical entities are stored. The most likely possible combination is intended to form the lexical output sequence.
Abstract:
A data signal for modifying a graphic scene displayed on at least one terminal, the graphic scene mode of a set of graphic objects and each object defined by at least one field. The data signal includes frames containing information for updating the graphic scene. Some of the frames also contain a command to completely replace the graphic scene with a new scene. Further, a method of transmitting a data signal to modify a graphic scene displayed on a terminal. Also, a terminal for displaying a graphic scene, the terminal processing a signal for modifying the graphic scene.
Abstract:
A pocket computer comprising a plurality of programs and data, loading of and access to said programs and data being managed by an operating system. The pocket computer comprises means for selecting one of at least two predefined contexts of use and a context database that comprises a list of associated programs and data for each predefined context of use. In response to selection of a context of use, the operating system interrogates the context database in order to activate from the plurality of programs and data only programs and data associated with said context in the context base.
Abstract:
In order to navigate in interactive voice services (PSV) implemented on a platform and accessible from a user terminal (TU) and executed in a first language in an interactive voice server (SVI), e.g., VXML, the voice services include identifiers of other voice services or of portions thereof, which in turn include returns to the voice services. In the platform (PSV) the description of a voice service from an administrator terminal (TA) is written in a high-level language of the invention which is converted into the first language during the service call so as to be executed in the voice server. Thus, the invention networks voice services while facilitating publishing thereof.
Abstract:
A half-wave printed “patch” antenna includes, symmetrically with respect to a plane of symmetry of the antenna perpendicular to faces of the antenna, a dielectric substrate and two conductive layers on respective faces of the substrate. One face of the substrate includes a raised portion extending lengthwise of the plane of symmetry and one of the conductive layers extends over and along said raised portion. Consequently, the antenna has a small size, combined with a more open radiation diagram. The antenna includes only one raised portion for linear polarization, or two raised portions or a raised portion with axial symmetry for crossed polarizations.
