Abstract:
The invention relates to an electrical energy distribution apparatus (1) for distributing electrical energy within an arrangement of electrical devices (3 to 7, 11). Assignments between priority classes and at least some of the electrical devices (3 to 7) are provided and distribution control information for controlling the distribution of electrical energy within the arrangement of the electrical devices (3 to 7, 11) is received. A distribution rules determination unit (9) determines distribution rules depending on the received distribution control information and the provided assignments, and an electrical energy distributor (10) distributes the electrical energy within the arrangement of electrical devices (3 to 7, 11) depending on the determined distribution rules. This determination of distribution rules depending on the assignments and the distribution control information, which may reflect, for example, actual costs of electrical energy, provides an adaptable distribution of electrical energy, which allows for improving this distribution.

Abstract:
The invention relates to guiding objects, like passengers in an airport, in particular, to an area indication system and a method for guiding objects, said objects being capable of moving and having one or multiple sensorial capabilities or a combination thereof, e.g. an optical and/or acoustical recognition capability. Said objects may include autonomic objects, people or animals. Further, the invention relates to a method for guiding objects. Provided is an area indication system having a control unit (16) and a plurality of e.g. visual indication elements like illuminated floor tiles (10). The control unit (16) is adapted to select an area (32; 34) for an object to be located in and to effect a property of the selected area (32; 34) by appropriately controlling a selected group of indication elements (10). The control unit (16) is adapted to select said group based on the selected area (32; 34) and based on positional information about the indication elements (10). For example, the property is a visual appearance like colour. Further provided is a guiding system having a control unit for selecting an area for an object to be located in, wherein a property of the selected area is communicated to the object.

Abstract:
The invention describes a method of commissioning a device arrangement comprising a number of devices (L1, L2, L3,) communicating with each other over a wireless networked control system (WN). This method comprises the steps of - reading a unique identifier (ID1, ID2, ID3) from an electronic identification tag (T) which is tagged to a device (L1, L2, L3) currently to be installed by means of a reading device (3) carried by an installer who is to install the device (L1, L2, L3), and - compiling an inventory (IV) of the installed devices (L1, L2, L3) using the read unique identifiers (ID1, ID2, ID3), - commissioning of the devices (L1, L2, L3) using the inventory (IV). The invention further describes a commissioning system (100) for commissioning such a device arrangement, a data logger and an installation tool (1) for installing devices (L1, L2, L3,) usable in such a commissioning system (100).
Abstract:
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 (14, 16, 18). 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.
Abstract:
The invention relates to a method of accommodating a network apparatus (2) in an existing network (A), wherein a user (1) supplies characteristic biometrical data to the apparatus (2) as well as to the apparatuses of the network (A) via a biometry module. A network identifier and/or a configuration key can then be derived from the biometrical data. The network identifier can ensure that the new apparatus (2) is correctly assigned to the desired network (A), also when there are still other networks (B) within its range. The configuration key can be used for securing the information exchanged during the configuration phase from interception.
Abstract:
The invention relates to a method and a packet switch for synchronising port controllers (1) with cross-connection means (40). By switching cross-connection means from loopback configurations (41a, 43a) to no-transmission configurations, consecutively an offset counter (32) in a port controller (1) may be altered until transmission of cells is synchronised, so as cells are switched within said cross-connection means (40) within transmission periods.

An electro-mechanical energy harvesting switch configured to provide at least two different control signals comprises: a generator activating member (9) configured to move between a rest position and a maximum loaded position; at least one spring (11, 13) configured to force the generator activating member towards the rest position; and a unidirectionally rotating protrusion member (17) comprising at least one protrusion (21) configured to move through a protrusion's path during rotation of the protrusion member (17), through a first position of the protrusion (21), in which first position the protrusion (21) is engaged with the generator activating member (9) in the rest position, and through a second position, the protrusion (21) thereby carrying the generator activating member (9) from the rest position to the maximum loaded position against the force of the at least one spring (11, 13).
Abstract:
The invention relates to automatically commissioning of devices of a networked control system, particularly to automatically commissioning of wireless switches in lighting control systems. A basic idea of the invention is to derive from an installation constraints with regard to a networked control system and to consider these constraints during an automatic commissioning process based on signal strength processing. This may help to improve the reliability of commissioning based on signal strengths. An embodiment of the invention relates to a method for automatically commissioning of devices of a networked control system, which comprises one or more first devices (S1-S3) and several second devices (RC1-RC3) being able to communicate wirelessly, wherein wireless signals from first devices (S1-S3) are received by one or more second devices (RC1-RC3) and for each received wireless signal the signal strength is determined, and wherein the commissioning comprises the following steps: processing the determined signal strengths considering constraints derived from an installation of the networked control system for commissioning, and assigning the first devices (S1-S3) to one or more of the second devices (RC1-RC3) depending on the processing result.
