The present invention relates to a method and apparatus for controlling power distribution by a control system that only requires a broadcast medium between a controller () and appliances or loads (-to-) and information about the current total power consumption of the system to precisely reach a target consumption level in a stepwise, fast converging way without 'seesaw' effects and with 'fair distribution' of any power reduction.

The invention relates to a method for replacing a device in a network comprising a plurality of devices. The method includes a step of storing () replicated data of a first device in a storage means, a step of removing () the first device from the network, a step of connecting () a second device to the network, a step of providing () a replacement information comprising the first identifier and a step of providing () the replicated data of the first device from the storage means to the second device.

The invention relates to a compiler and a method for compiling control logic for a plurality of devices of a networked control system, particularly to the automated assignment of control logic to devices. The invention provides with a compilation an automatic assignment procedure of an executable runtime code to devices of a networked control system. The assignment process of control logic to the devices may take various optimization criteria into account which include various distribution aspects, e.g. network resources or capabilities, such as available bandwidth or reliability of the network links, and device resources or capabilities, e.g. CPU, memory, power source or sleeping behavior which may influence the observed behavior of the devices, e.g. due to transmission delay or data packet loss.

The invention relates to composing a lighting atmosphere from an abstract description for example a lighting atmosphere specified in XML, wherein the lighting atmosphere is generated by several lighting devices, by automatically rendering the desired lighting atmosphere from the abstract description. The abstract description describes the type of light with certain lighting parameters desired at certain semantic locations at certain semantic times. This abstract atmosphere description is automatically transferred to a specific instance of a lighting system (). The invention has the main advantage that it allows to create light scenes and lighting atmospheres at a high level of abstraction without requiring the definition of a lighting atmosphere or scene by setting the intensity, color, etc. for single lighting units or devices which can be very time consuming and cumbersome, particularly with large and complex lighting systems comprising many lighting devices.

Networked control systems and methods include a plurality of devices connected to a network. At least one device has a logical address that includes a device type and a device location in an environment of the device in a user readable and understandable format, such as English or other languages. The system further includes a processor connectable to the network and configured to execute control logic using the logical addresses. A memory is provided for storing a mapping from the logical address to a physical network address of the device.

Networked control system using logical addresses

A telecommunication network includes a number of mutually coupled private branch exchanges to which are assigned respective storage locations for storing switching data and which include processors for determining the most favorable route in dependence on the stored switching data to a subscriber terminal arranged inside or outside the telecommunication network. In the network, an outgoing route from one of the private branch exchanges is led through one or more of the other private branch exchanges and/or through one or more other telecommunication networks.

Telecommunication network with least cost routing

The invention relates to a telecommunication system comprising a plurality of mutually coupled switching centers and at least one coupled control unit. When switching centers assign paths based on switching data stored in switching tables, switchings take place first between the coupled switching centers which have each their own switching tables containing LCR data. The respective switching center recognizes only the beginning and end of the path in the case of an incoming call, so that the call may be permanently switched to and fro between two switching centers leading to an endless loop in the case of a current overload or interruption of the path from the switching table. For realizing an improved switching environment while system features are taken into account, the control unit is provided for forming at least one connection tree which comprises as branches loop-free connections from one switching center and running to other switching centers of the telecommunication system and for converting the connection tree into a switching tree by determining pairs of switching centers in the branches and by erasing at least one branch that contains the respective pair in reverse order. This reduction creates loop-free switching trees from the connection trees, because an endless loop between two nodes is avoided with the switching operation. The respective branches correspond to the possible loop-free connections in the network. Since a switching tree is formed for each switching center, groups of loop-free connections for the whole telecommunication system evolve in this manner.

Telecommunication system with loop-free switching tables

A communication system includes subscriber terminals which can be coupled via at least one switch, and to which subscriber terminals, several call numbers can be assigned for which telecommunication parameters are definable. The subscriber terminals each store respective telecommunication parameters. In the case of a change of assignment of a subscriber call number from a first subscriber terminal to a second subscriber terminal, the telecommunication parameters belonging to the subscriber call number are transmitted to the second subscriber terminal. The communication system is preferably implemented in ISDN switching systems with ISDN telephones as terminals.
