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 relates to a system and method for controlling a lighting system by automatically detecting the position of objects. A basic idea of the invention is to automatically detect the positions of objects, particularly movable objects like mannequins, and to control a lighting system depending on the detected positions by automatically processing the detected positions in a process of creating a certain lighting atmosphere created by the lighting system from an abstract description of the lighting atmosphere (abstract atmosphere description). According to an embodiment of the invention, a light control system (10) with automatic position detection of objects (14) is provided, wherein the light control system (10) is adapted - to automatically create light control values for rendering light effects associated with the objects, - to automatically detect the positions of objects (14), and - to automatically adjust the created light control values depending on the detected positions of objects (14).

Abstract:
The invention describes a method of establishing a wireless multi-hop network (NW), in particular a ZigBee-type network, comprising a plurality of devices (0, 1, 2, …, 96) of a device arrangement (D), in which method devices (1, 2, 3, …, 96) establish a physical wireless connection to at least another device (0, 1, 11, 16, 17, 29, 30, 39, 48, 52, 53, 55, 64, 71, 73, 79, 88) of the network (NW) in a self-organizing process. In the self-organizing process a seeking device, intending to join the network, listens for beacon signals emitted by candidate parent devices already in the network comprising a network identifier and a device identifier of the emitting devices. Then, in a parent selection process, the seeking device selects a parent device from among the candidate parent devices, according to given selectionrules, based on the network identifiers (EPID), acceptance capabilities of the candidate parent devices, and link quality parameter values relating the device and the candidate parent devices. In this parent selection process application-level connection data (L, BI) of the seeking device and/or the candidate parent devices are applied. At least, the seeking device connects physically, and preferably also logically, via the selected parent device (0, 1, 11, 16, 17, 29, 30, 39, 48, 52, 53, 55, 64, 71, 73, 79, 88) to the network (NW). The invention further describes a device comprising a network interface for connecting a wireless multi-hop network (NW) according to this method.

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 behaviour which may influence the observed behaviour of the devices, e.g. due to transmission delay or data packet loss.
