Abstract: The invention relates to a method for managing light settings of a luminaire communicatively connected to a local coordinator. The method, performed by the luminaire, includes steps of providing to the local coordinator a control state of the luminaire (e.g. occupancy status), receiving from the local coordinator a power reduction factor for the luminaire, the factor being based on the control state of the luminaire and on control states provided to the local coordinator by one or more additional luminaires, determining new illuminance settings for the luminaire by applying the received factor to current illuminance settings, measuring luminance within a sensing region of a light sensor of the luminaire while one or more light sources of the luminaire emit light according to one or more operating parameters, and, based on the measured luminance, adjusting the operating parameters to achieve the new illuminance settings.

Abstract: The invention relates to a monitoring system (13) for monitoring electrical devices (A, B, C, D, K) like luminaires. An assignments providing unit (7) provides assignments between the electrical devices and behavior classes defining expected behaviors, wherein a deviation determination unit (9) determines a deviation a) between a monitored behavior of an electrical device assigned to a behavior class and an expected behavior defined by a behavior class and/or b) between a monitored behavior of an electrical device and a monitored behavior of another electrical device, wherein an output unit (10) provides an output depending on the determined deviation. The deviation can be indicative of a commissioning error, i.e., for instance, of an assignment of an electrical device to a wrong room within a building. The monitoring system can therefore allow for an automatic detection of commissioning errors in a building which may have thousands of electrical devices.

Abstract: A localization system comprising a plurality of wireless reference nodes for detecting a location of a mobile device within an environment. Each node transmits localization beacon signals to be detected by the mobile device, and/or listens for localization beacon signals from the mobile device. Further, the system also provides or contributes to providing another utility into the environment (e.g. each node being a luminaire); and transmits and/or listens for control-related signals, other than localization beacon signals, related to controlling the provision of said utility, the control related signals being communicated on a same or overlapping frequency band as the localization beacon signals, one or more controllers are configured to control the transmission of and/or listening for the control-related signals to be time-multiplexed into different time slots than the transmission and/or listening for the localization beacon signals, between the time-slots of the control-related signals.

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: A computer-implemented method of optimizing non-uniform quantization boundaries for a quantization unit of a sensor is provided. The method comprises: obtaining a digital representation of a model (120) for predicting the target metric (124) from an unquantized sensor signal (122), the model being defined by at least the quantization boundaries, the model comprising: a first layer (130) of multiple continuous quantization functions (142, 144, 146; ƒ1, . . . , ƒQ), the quantization functions approximating block functions on quantization intervals defined by the quantization boundaries and receiving as input an unquantized sensor signal, and a second layer (132) comprising a function taking as input the output of the multiple continuous quantization functions and generating as output a prediction of the target metric, and training (530) the model using the training data by iteratively updating (126) the quantization boundaries.

Abstract: A calibration method comprising, for each of one or more light sensors: (a) under influence of one or more substantially non-zero illumination levels in the target environment, using the light sensor to measure the sensed light level corresponding to each of these one or more illumination levels; (b) receiving a template light level value corresponding to each of the one or more illumination levels, representing the light level at a target location in the target environment substantially removed in space from the location of the light sensor, each of the one or more template light level values being assumed for the environment rather than measured by a light meter; and (c) determining a relationship between the sensed light level and the light level experienced at the target location, based on an evaluation of the one or more sensed levels relative to the one or more template light level values.

Abstract: In one aspect, a mobile device is located using a signal sent out from the mobile device to nodes of a location network, and the mobile device also sends a tracking preference associated with the signal. This specifies whether a location network is permitted to use the signal to determine the mobile's location, and/or whether a provider of a location related service associated with a location network is permitted to make use of the location. In embodiments the preference may be tagged with the ID of a particular provider. In another aspect, the localization is based on measurements taken by a mobile terminal of signals sent from the nodes, and the nodes also send out an identifier with the signal identifying a provider of a location related service associated with the network. The mobile device can then use this identifier to determine who to share its measurements or location with.

Abstract: A method of testing a sensor unit which detects, locally at the sensor unit, whether a person appears in the images it captures. The method comprises causing a light-emitting device (e.g. screen of a user terminal) to emit a test pattern toward the sensor unit to be captured over a series of images, the test pattern comprising a spatio-temporal pattern of light simulating presence of a predetermined number of people. The method further comprises, at a processing apparatus external to the sensor unit, receiving one or more presence detection reports from the sensor unit indicating an apparent people count detected using the sensor unit when subject to the test pattern. The apparent people count is then compared with the predetermined number of people simulated by the test pattern. Based on this comparison, it is determining whether the sensor unit is functioning correctly.
