摘要:
The present invention relates to a context-based service look up, wherein a service instance, having a scope (O), comprises at least one service instance data set (b) having a hierarchy of levels. A service consumer data set (a), having a hierarchy of levels is received from a service consumer (1), having a situation (S). Comparisons are made of each service consumer data set with each service instance data set, for the same level. Dependent on results of the comparisons, it is determined whether said situation (S) of said service consumer (1) matches said scope (O) of said service instance.

A system and method for processing of markup language information, such as extensible markup language (XML) based control information is disclosed. The system comprises a compression sender entity and a decompression receiver entity. The sender entity uses its internal, binary representation derived from textual XML-based protocol header and encodes the binary representation as a tag-length-value (TLV) binary value. The TLV binary value is embedded as encoded data in a specifically marked comment, which may be detected by the receiver entity. The receiver entity builds up an internal, binary data structure based on the encoded data representing the original XML data. The system avoids the usage of string data to represent a small set of well known strings and uses a more compact binary encoding which reduces space and time to process the data.

A method for tracking a plurality of containers each joined to an electronic tracking device having routing capabilities and a WPAN-enabled radio receiver/transmitter configured to attempt to connect to a pre-configured WPAN upon being activated comprises activating the radio receiver/transmitter of each tracking device joined to a container being loaded onto a cargo vessel; receiving an indication from each tracking device that fails to connect to the WPAN; intermittently performing a network scan to locate each WPAN-connected tracking device; intermittently configuring the WPAN to include each WPAN-connected tracking device in a hybrid tree-mesh network topology; intermittently configuring routing information stored on each WPAN-connected tracking device to maintain mutual communication with each WPAN-connected tracking device and enable mutual communication between each WPAN-connected tracking device; receiving transport-related data from each WPAN-connected tracking device; transmitting the transport-related data to a control station through a LAN on the vessel; broadcasting a request to be routed between the WPAN-connected tracking devices in a depth-first traversal of the network topology that directs each WPAN-connected tracking device to enter a low-power mode when the depth-first traversal backtracks from the tracking device; and receiving an acknowledgment of the request communicated from each WPAN-connected tracking device when the tracking device enters the low-power mode.
摘要:
A WPAN system for establishing communication between a control station of a cargo vessel and a plurality of containers that are loaded onto the vessel is provided that comprises a base station configured to establish and manage a pre-configured WPAN having a hybrid tree-mesh network topology and a plurality of electronic tracking devices each being provided with a WPAN-enabled radio receiver/transmitter and routing capabilities. The base station is configured to communicate with the control station through a local area network on the vessel. Each tracking device is configured to be joined to a respective container of the plurality of containers and to connect to the WPAN upon being activated. The base station is configured to intermittently perform a network scan to locate each tracking device that is connected to the WPAN and dynamically reconfigure the network topology to include each tracking device connected to the WPAN to maintain mutual communication with each connected tracking device using the routing capabilities of the tracking devices.
摘要:
A system and method for providing a consistent view of data stored therein, which can change dynamically in an uncoordinated way, includes a client program and a snapshot server program. The snapshot server program permits one or more client programs to request snapshots of data from the snapshot server program such that the data included in or referenced by a snapshot originates from one or more host server programs and the data is accessible to the snapshot server program, but is managed independently of the snapshot server program.

A system is provided for transmitting generally static media. The system (10) comprising an electronic device (12) and a digital audio transmitter (14). The electronic device (12) has a CPU (16), a storage medium (18), a display (20), a user interface (22), and a digital audio broadcast receiver (26). The digital audio transmitter (14) has a specialized broadcast server (30). The digital audio broadcast receiver (26) receives and decodes the digital audio signal transmitted by the digital audio transmitter (14).

摘要:
A computer-readable medium is encoded with a method of externalizing legacy data from a legacy database on a data resource into an Extensible Markup Language (“XML”)-compliant format where the format is specified by an automatically generated XML meta-description, thus enabling access and processing of legacy data by XML-compliant applications.
