The present invention relates to an energy allocation system for operating at least an energy storage device to substantially balance the energy consumed by the energy storage device with the energy supplied thereto, comprising the steps of: determining a power flexibility of the energy storage device by generating an upper time-varying power function; predicting energy consumption data per discrete time-slots over a given time-window for the device; predicting a demand for energy by the device in a given planning time-period; generating a time-varying upper energy function for the demand prediction that defines an uppermost limit for the supply of energy to the device; generating a time-varying lower energy function for the demand prediction that defines a lowermost limit for the supply of energy to the device, and supplying energy to the device in a range defined by the limits specified by the upper energy function and the lower energy function.

Energy allocation system for balancing energy consumption

The present invention relates to a context-based service look up, wherein a service instance, having a scope includes at least one service instance data set having a hierarchy of levels. A service consumer data set, having a hierarchy of levels is received from a service consumer, having a situation. 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 of said service consumer matches said scope 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.

Methods, systems and apparatus for facilitating access by a user to a resource of an on-line service via a data communications network, the resource being accessible via an entry page of the service. A method includes checking whether a user condition, prestored in the network, is satisfied, the user condition being associated with the user and relating to the resource. If the condition is not satisfied, the entry page is sent to the user via the network. If the condition is satisfied, the entry page is modified by adding an indication relating to the resource. The modified entry page in then sent to the user advantageously, the method also includes transmitting to the user a notification message in response to, and indicative of, the condition being satisfied.

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.

A method of establishing a trustworthiness level of a participant in a communication connection between a first communication partner and a second communication partner is proposed whereby the communication behavior is adapted to the established trustworthiness level. The participant is equipped with a trustworthiness certificate and a therefrom separated securely stored participant private key. The first communication partner receives the trustworthiness certificate from the participant wherefrom the trustworthiness level is derived and established. The first communication partner tests whether the trustworthiness certificate belongs to the participant by using the participant private key. In case the trustworthiness certificate is confirmed by the test to belong to the participant, the first communication partner communicates the established trustworthiness level to the second communication partner. Then, at least one parameter of the communication behavior is chosen in dependence of the established trustworthiness level.

A method, system, and computer program product for establishing security parameters that are used to exchange data on a secure connection. A piggy-backed key exchange protocol is defined, with which these security parameters are advantageously exchanged. By piggy-backing the key exchange onto other already-required messages (such as a client's HTTP GET request, or the server's response thereto), the overhead associated with setting up a secure browser-to-server connection is minimized. This technique is defined for a number of different scenarios, where the client and server may or may not share an encoding scheme, and is designed to maintain the integrity of application layer communication protocols. In one scenario, a client requests a server to propose a message encoding scheme. If the client has security-sensitive data to transmit with its request, it waits for the proposed scheme before sending this sensitive data to the server. Otherwise, the server may inform the client of the message encoding scheme in the same transmission used to send a response to a client's request.

A method, system, and computer program product for exchanging supplemental information fields between a client and server. This supplemental information can then be used by the server to complete a client's request for content stored at a particular location. For example, the supplemental information may be used to provide a customized response, or for access control to sensitive data. Preferably, the REDIRECT message of the Hypertext Transfer Protocol (HTTP) or the Wireless Session Protocol (WSP) is used to request the supplemental information, encoding a comma-separated list of attribute names in a request header for the desired supplemental information. This solution is designed to be backward-compatible.
