Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: 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.

Abstract: An illumination system and method is disclosed. In one example, the illumination system comprises a light source, a controller controlling the power output of the light source, and a light sensor wirelessly communicating with the controller. In a normal mode, the controller controls the light source such that the light level remains substantially constant. In a change mode, the controller controls the light source such that the light level is gradually changed with a predetermined change rate so as to decrease a deviation from a target level. The controller switches from the normal mode to the change mode on the basis of input signals received from the light sensor. The light sensor measures a light level, and decides whether or not to communicate a signal to the controller. The light sensor refrains from transmitting a signal when receiving the signal does not cause the controller to change its control behavior.

Abstract: Greater network utilization is implemented through dynamic network reconfiguration and allocation of network services and resources based on the data to be transferred and the consumer transferring it. A hierarchical system is utilized whereby requests from lower layers are aggregated before being provided to upper layers, and allocations received from upper layers are distributed to lower layers. To maximize network utilization, paths through the network are reconfigured by identifying specific types of packets that are to be flagged in a specific manner, and then by further identifying specific routing rules to be applied in the transmission of such packets. Network reconfiguration is performed on an incremental basis to avoid overloading a path, and capacity can be reserved along one or more paths to prevent such overloading. Background data is agnostic as to specific transmission times and is utilized to prevent overloading due to reconfiguration.

Abstract: A system for derivation and provision of anonymised cellular mobile network data for population density and mobility report generation can be implemented on a computer, e.g. in a data warehouse system. The system includes effective anonymisation measures to protect the privacy of the mobile network customers. It comprises a load extractor and a database production environment, where the load extractor is connected with the mobile network to receive and anonymise traffic data from a mobile communications network, and where the production environment is set up to allow a third party to query the traffic data for the purpose of population density and mobility report generation. The production environment of the system presents itself as a “black box,” which can be operated by the third party only via specific interfaces. Thus, the system can be operated by a third party without compromising the privacy of the mobile network users.

Abstract: A collaboration program operates on a computer system for storing, sharing and synchronizing data between different users. Centrally stored content data items are organized by associations into one or more folders, with the folders arranged by associations in a multi-level hierarchical structure. Users have access to all folders and content data items falling within at least one top level folder or “file cabinet” viewable by that user. When a user makes a change/addition to the hierarchical structure, that change/addition is transmitted to a server, which makes the change/addition to the necessary associations and sends messages through a TCP/IP format advising other signed-on users of the change/addition. The computer system operating the collaboration program gives different users simultaneous, synchronized access to the folders and content data items in the hierarchical structure.
