A binary-coded structure document, (e.g., in an EXI format which is based on a structure document designed in a text-based description language, such as XML), is provided with a binary-coded index document, which is based on a structural part of the structure document. A storage representation of the binary-coded index document is stored in a working storage unit of the device, and the binary-coded structure document is stored in a background storage unit assigned to the device. A processing operation or a request by at least one processing process is carried out by accessing the storage representation of the binary-coded index document via an object interface, and in certain examples, fragments of the binary-coded structure document are loaded into the working storage unit by the object interface. By carrying out processing operations on the binary-coded index document, faster request operations are facilitated in that specific requests may already be processed using the index document BCI without the involvement of the binary-coded structure document.

Methods and systems are provided for optimizing the distribution of electrical energy in an electrical power supply system which includes autonomous supply system regions, including the method steps of: &#x2014;receiving input data by at least two dispatcher instances, wherein the input data represents energy intervals which are requested by the autonomous supply system regions; &#x2014;calculating at least one solution of the distribution of electrical energy to the supply system regions by each of the at least two dispatcher instances; &#x2014;selecting one of the calculated solutions for the distribution of electrical energy in the power supply system by a leader election. The disclosed relates to the technical field of distributing electrical energy and can be used, for example, for smart grids.

Optimizing the distribution of electrical energy

A communication device includes a transceiver unit for receiving from a central installation a broadcast message containing information for initiating communication between the communication device and the central installation, and a control unit for selecting a hardware address for the communication device in response to the information contained in the broadcast message. The selected hardware address can be used for addressing the communication device for messages from the central installation. The transceiver unit is designed to communicate with the central installation using the selected hardware address for the duration of a session. The control unit is designed to delete the selected hardware address after the duration of the session has expired. Selecting a hardware address randomly and deleting the hardware address after the session has expired allows communication between the communication device and the central installation, while maintaining the identity of the communication device anonymous.

The present invention relates to methods and apparatuses for allocating amounts of energy for prosumers, wherein the prosumers provide minimum and maximum amounts of energy for a future interval of time and the respective amounts of energy from the prosumers are generated in such a manner that, on the one hand, a relative position of the amount of energy within an interval for the particular prosumer, as defined by the minimum amount of energy and the maximum amount of energy, assumes an identical value for all prosumers and, on the other hand, a sum of the amounts of energy from all prosumers produces a value of zero. The invention can be used in the distribution of amounts of energy in a power supply system having conventional energy producers and energy consumers as well as in novel participants in the power supply system which can both consume and provide energy, for example an electric vehicle.

Methods and apparatuses for allocating amounts of energy

In a method and an apparatus () for searching in a memory-efficient manner for at least one query data element in a graph (A), only as many data elements are read into a memory as are required for their subsequent processing. Increased memory efficiency is ensured as a result of this. The proposed apparatus is particularly suitable for use in terminals having very limited memory, in particular in mobile terminals.
