20140247695 | METHOD FOR ROBUST AND FAST PRESENCE DETECTION WITH A SENSOR - A method is presented for detecting the presence of objects. The method differentiates animate objects within a presence detector detection area from inanimate objects within the detection area. Moving objects passing nearby the detection area are further distinguished from objects entering or leaving the detection area. The method distinguishes inanimate objects from dormant animate objects within the detection areas. | 09-04-2014 |
20150048954 | CONTROL OF LIGHTING DEVICES - A network of active sensors in a control system is considered. The active sensors, which may be fixed-infrastructure sensors, provide presence detection information to a distributed lighting system. The active sensors communicate by transmitting probe signals. The communication of probe signals may result in cross-interference which may vary in time. Cross-interference is detected, and can later be avoided, by determining a difference between signals received in a first part of a timeslot and signals received in a second part of the timeslot. In order to do so probe signals comprising two non-zero pulses are transmitted in respective parts of the timeslot. Applications are, for example, active presence sensors in lighting control applications in indoor as well as outdoor environments. | 02-19-2015 |

20160066391 | ANTI-TAMPERING DAYLIGHT HARVESTING SYSTEM - The present invention relates to a method for controlling a lighting device in a daylight harvesting system. When a user tampers with a sensor, in order to decrease the light level light level measured and therefore increase the light intensity of the lighting device, the tampering is detected. Based on this tamper detection the light intensity of the lighting device is controlled based on a set value (e.g. 70% dimming). | 03-03-2016 |
20160073475 | CALIBRATION OPERATION OF A LIGHTING DEVICE - A controller comprising: presence detection logic, calibration logic, and an input for receiving a reading from a light sensor representing a sensed light level. The presence detection logic is for detecting presence events based on a presence sensor, and is configured to indicate a set-point to operate at least one lighting device in dependence on a positive detection of presence. The calibration logic is for performing a calibration operation, which is performed by causing a light output of the lighting device to change between a first, lower level and a second, higher level, and by and calibrating the set-point based on the reading from the light sensor under influence of the first and second levels. The calibration logic is configured to trigger this calibration operation in response to the positive detection of presence. | 03-10-2016 |
20160077197 | MITIGATING DISTURBANCE IN SENSING - A signal processing module for use with a receiver for receiving echoes of an emitted signal. The signal processing module comprises sensing logic for sensing presence of a being or object in a space using echoes of the signal as reflected from the being or object, wherein the echoes are received with an associated frequency band. The signal processing module further comprises control logic for detecting disturbance having potential to compromise said sensing, wherein the signal processing module is configured to detect this disturbance by listening for an unwanted signal in a region of the spectrum outside the frequency band of the echoes, and to adapt the sensing in dependence on the detected disturbance. | 03-17-2016 |

20160088714 | CONTROLLING A FUNCTION OF A SPACE - A controller for use with a sensing apparatus that comprises a receiver for receiving echoes of an emitted signal. The controller comprises a control module for sensing a being in a space based on the echoes, configured to provide a function of the space in dependence on the sensing; and a timer configured to prevent a change in state of the function for a period after a result of the sensing. The control module is further configured to dynamically measure an estimate of disturbance received by the receiver and adapt the period based on the estimated disturbance. | 03-24-2016 |
