Abstract:
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.
Abstract:
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.
Abstract:
The invention relates to adjusting at least one of installed building service sensors (10) of a building service system. A sensor coverage area of at least one sensor (10) is adjusted based on information on a position of the installed sensor (10) relative to at least one other sensor (10). For example, to determine the position of the sensor (10) relative to said at least one other sensor (10), each sensor (10) establishes a wireless communication between said sensor (10) and at least one other sensor (10) via a wireless communication means (34) of the sensor (10). For example, information on the positions of the installed sensors (10) is used to assign to each sensor (10) at least one of installed building service supply devices (12) of the system.
Abstract:
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.
Abstract:
Apparatuses (1) for mapping devices (21-29) to representations (31-39) of the devices (21-29) in models comprise displays (11) for displaying representations (31-39), memories (12) for storing triggering information defining triggering procedures for triggering the devices (21-29), inputs (16) for receiving identifying information comprising identifiers from devices (21-29) that have been triggered, and processors (14) for linking the identifiers and the representations (31-39) at the hand of the triggering procedures. The commissioning of devices (21-29) is done faster and more user-friendly. The triggering procedures may define the devices (21-29) to be triggered in a sequence. The processor (14) can then link the identifiers and the representations (31-39) via the sequence. Alternatively the triggering procedures may define unique codes to be allocated to the representations (31-39) and to be provided to the devices (21-29), with the identifying information further comprising the codes. The processor (14) can then link the identifiers and the representations (31-39) via the codes.
