A system and methods for automatically commissioning electrical fixtures using sound are disclosed. Electrical fixtures (-) detect sounds produced by a sound generator moved along a path () through installed fixtures according to a building plan (). Each electrical fixture may be associated with a mapped fixture location in the building plan by correlating the detected sound with the location of the sound generator along the path.

System and method for commissioning lighting using sound

A method determines the relative locations of wirelessly controllable service device nodes and switching control nodes within a building. At least some of the service device nodes are located in different rooms of the building and should be allocated to switching control nodes on a room-specific basis. Wireless communication is established between the nodes to determine relative spatial positions of selected nodes using received signal strength indication (RSSI) values indicative of a distance of separation between two communicating nodes. The service device nodes are then grouped into two or more groups, a first group corresponding to service device nodes in one room and a second group corresponding to service device nodes in a second room, based on spatial distribution of the service device nodes as indicated by the RSSI values. The service device nodes of each group are then allocated to at least one associated switching control node.

Grouping wireless lighting nodes according to a building room layout

A computer algorithm () employing decision trees in order to assign wireless communication nodes (--) in a derived spatial arrangement. In a first embodiment, the algorithm () assigns nodes to an array of positions corresponding to the positions of luminaires (-) in a lighting array () to enable the lighting array () to be commissioned automatically. In a second embodiment, the algorithm () assigns nodes to control groups (-) such that the member nodes of a particular control group (-) may be controlled by a single switch or sensor (-). The use of decision trees allows the final assignment of nodes to be delayed until more information has been taken into account, thus, the algorithm () is able to select the best overall configuration.

Use of decision trees for automatic commissioning

A computer algorithm for grouping a derived spatial arrangement of wireless communication nodes. The wireless communication nodes form a wireless communication network and are configured to control the operation of luminaires in a lighting array. The position of each node in the communication network corresponds to the position of a particular luminaire in the lighting array. The algorithm divides the arrangement of nodes into a plurality of spatial groups, each of which is defined by a line which joins the group's member nodes together. The groups are ranked according to their statistical attributes and a number of groups are selected as control groups, such that the member nodes, and hence luminaires, of each control group may be controlled by a single switch or sensor.

Using position for node grouping

A method for matching an actual device in a wireless network to a corresponding device indicated in a plan of such devices is provided. The method is suitable for initiating the commissioning process for a lighting control network or an automated home network and it enables the program controlling the system to establish a number of reference nodes, with respect to which the coordinates of the rest of the nodes in the network are established, without the engineer having to manually enter the identification details of the reference nodes in the computer system. The method includes identifying a device in the plan having unique characteristics compared to the other devices in the plan, receiving data comprising the characteristics of the actual device from the wireless network, and in response to the characteristics of the actual device including the unique characteristics, matching the physical device with the identified device.

Locating reference nodes for positioning devices in a wireless network

An electronic device has first and second wireless transceiver modules using first and second communication protocol, respectively. Both wireless transceiver modules are coupled between an application layer and an at least partially shared physical layer of the electronic device. The second wireless transceiver module is equipped with a controller to avoid interference with external signals on a frequency used by the second communication protocol. To avoid destructive interference in the physical layer resulting from simultaneous communications from or to the first and second wireless transceiver modules, the electronic device further includes a mediator, which is responsive to an enabled communication involving the first wireless transceiver module, and which feeds a blocking signal into the controller to avoid interference between the enabled communication and a transmission of the second wireless transceiver module.

Electronic device, method and communication system

A method of reconfiguring the software interface in software defined radios in which when a transmitting station (PS) sends a reconfiguration software message to a receiving station (SS), the receiving station responds with a message giving an estimated time duration for carrying-out the reconfiguration of its software. The transmitting station listens for the estimated time duration for a message which confirms that the receiving station has been successfully reconfigured and commences normal communications using the new configuration. The estimated time duration may be computed using indicia present in the reconfiguration software message.
