Apparatuses () for mapping devices (-) to representations (-) of the devices (-) in models comprise displays () for displaying representations (-), memories () for storing triggering information defining triggering procedures for triggering the devices (-), inputs () for receiving identifying information comprising identifiers from devices (-) that have been triggered, and processors () for linking the identifiers and the representations (-) at the hand of the triggering procedures. The commissioning of devices (-) is done faster and more user-friendly. The triggering procedures may define the devices (-) to be triggered in a sequence. The processor () can then link the identifiers and the representations (-) via the sequence. Alternatively the triggering procedures may define unique codes to be allocated to the representations (-) and to be provided to the devices (-), with the identifying information further comprising the codes. The processor () can then link the identifiers and the representations (-) via the codes.

Mapping devices to representations in a model

The invention relates to adjusting at least one of installed building service sensors () of a building service system. A sensor coverage area of at least one sensor () is adjusted based on information on a position of the installed sensor () relative to at least one other sensor (). For example, to determine the position of the sensor () relative to said at least one other sensor (), each sensor () establishes a wireless communication between said sensor () and at least one other sensor () via a wireless communication means () of the sensor (). For example, information on the positions of the installed sensors () is used to assign to each sensor () at least one of installed building service supply devices () of the system.

For ensuring reliability of data transmission in a wireless mesh network, while reducing the data overhead of the transmissions, a node for a wireless mesh network and a method of controlling the same are provided, wherein the node is configured to decide about retransmission of a message received from a transmitting node, based on whether the transmitting node has at least one layout element of a layout plan in common with the node, at least one of the layout elements of the layout plan being associated with the node.

Optimizing message forwarding in a wireless mesh network

Disclosed is a method for controlling a light output signal emitted by a set of light sources comprising at least one light source, wherein said light output signal includes a modulation signal which carries individual information, such that the method includes recurrently:

Adaptive modulation and data embedding in light for advanced lighting control

Remote controllers, positioning systems, and methods configured for the efficient assignment of addresses in a coded lighting positioning system are proposed. Particularly, a proposed remote controller comprises a receiver for receiving coded light from a light source in a coded lighting positioning system, where the coded light comprises an initial light source identifier of the light source. The remote controller also comprises a processing unit for assigning a modified light source identifier to the light source based on the received coded light, and a transmitter for transmitting the modified light source identifier to the light source. The modified light source identifier is a locally unique identifier used to provide positional information.

For load balancing in a large-scale wireless mesh network, a device, a system and a method are provided for controlling data packet transmissions in the wireless mesh network, wherein a time slot is randomly selected within a determined answer interval for transmitting an answer responding to a received data packet.

Device and method for scheduling data packet transmission in wireless networks

This disclosure relates to communicating on a wireless channel in the presence of an interference source. A receiver accesses the channel to perform a sequence of energy detections. The interference source is modelled as cyclically transitioning into and out of an inactive state and as cyclically transitioning, when out of the inactive state, between a first active state, in which the interference source is active and creating interference on the channel, and a second active state, in which the interference source is active but creating a substantially lower level of interference on the channel. Based on the sequence of energy detections, large and small time scale metrics are determined. Transmission of data by a transmitter is in dependence on the estimated metrics.

Modelling interference

In order to increase transmission reliability and transmission efficiency in the presence of interference at a transmitting or receiving node of a wireless network a device for controlling the node of the wireless network is provided, wherein the node is associated to at least one load unit. The device comprises a control unit that is adapted to adjust a communication mode of the node based on an operation state of the load unit.

Device and method for controlling a node of a wireless network

For improving the protection of a network against denial of service attacks and other hostile attacks, while keeping the operation of the network simple and efficient and considering restricted capacities of single network nodes, a control unit, a system and a method for operating a network with a plurality of nodes are provided, wherein at least one operation parameter of at least one node is adjusted based on a current network phase and a data packet received by the node () is processed based on the operation parameter.

Avoidance of hostile attacks in a network

The disclosure describes is a channel switching strategy and corresponding protocol for a mesh network which comprises a segment controller (SC) and a large number of outdoor luminaire controllers (OLCs) or other network nodes. A channel switching process is initiated and managed by the SC which transmits a channel switching command to all nodes in the system. Following the actual channel switch, the SC delegate's responsibility to request an orphan node to switch to the new channel to a selected delegate node which is a neighbor node of the orphan node. The selection of the delegate node may be based on a prioritization. When an OLC does not receive any messages for a specified, prolonged period of time, it may scan available frequency bands to find the (new) channel in which the networked system operates at that time.

Commissioning of a building service system

The invention provides a light control system for a lighting network, including a plurality of light units wherein at least one light unit includes at least one sensor type, a distributed/centralized controller/central management system in communication with one or more of the light units, said controller/central management system sends control commands to one or more of said light units, in response to received light unit status/sensor information from one or more of said light units and/or status information from a connected device, and implements a lighting strategy relating to the characteristics of the plurality of light units, wherein the one or more neighboring light units' sensor type's detection threshold are adjusted using a predetermined strategy based on the new lighting strategy of the at least one light unit or the status information from the connected device.

The method further comprises the step of operating the at least two light sources such that the color coordinates of the light emitted from the at least two light sources are maintained over time within a first, bounded interval (), and the luminous intensity of the light emitted from the at least two light sources is maintained over time within a second, bounded interval ().

Method, light module and receiving unit for light coding

Proposed is a light module () comprising at least two primary light sources () capable of emitting a primary color light. This allows the light module to emit light having intensity (Y) and color coordinates (x,y) through additive color mixing of the constituent primary colors. The light module further comprises an modulator () capable of modulating the primary light sources enabling embedment of data in the light emitted. The modulator () is arranged to modulate the color coordinates of the light emitted for embedding the data. This is especially advantageous as the sensitivity of the human eye to changes in color is lower than to changes in intensity. The invention thus advantageously allows embedding the data into the light emitted from the light modules () of an illumination system () without reducing the performance of its primary function as an aid to human vision.
