    摘要: Methods for exchanging signals via a network with nodes (11-15) improve the performance of the network by letting a destination node (12) s receive the signals originating from a source node (11) via different first and second signal routes, and by processing and correlating these signals in the destination node (12). In dependence of a correlation result, a process for processing a signal in a node (11-15) is adjusted. This process may be situated in the destination node (12), or in the source node (11) or an io intermediate node (13-15), in which case a control signal is to be exchanged. A learning algorithm for the adjusting of the process can be run in the nodes (11-15). Label switched routing can be introduced, whereby the label signal is sent from the source node (11) to the destination node via a third signal route different from the first and second signal route, to improve the efficiency of the nodes (11-15).

    摘要: Proposed is an object localization method, system and user interface device for locating a (misplaced) object (10) in an area of a construction (1). The method comprises the steps of (i) identifying the object (10), (ii) providing an illumination device (20) comprising a plurality of light sources (30) modulated to emit light comprising light source identification codes (35), (iii) illuminating the tag (11) with light emitted by the light sources (30), (iv) requesting the tag (11) to measure the illumination and to identify the light sources (30) illuminating the tag by their light source identification codes (35), (v) transmitting object location data from the tag (11) relating to the measured illumination and light source identification codes (35) to a master controller (25) arranged to control the illumination device (20), (vi) providing a feedback signal related to the object (10) using the master controller (25). The method is characterized by using a lighting infrastructure (27) of the construction (1) in providing the illumination device (20). Advantageously, the method enables a user to obtain a feedback signal about the location of the desired object without the need to move through the construction. Instead, the method enables the user to locate many objects within a construction or area from a single fixed position.

    摘要: A method for driving a lamp (2) comprises the steps of: generating a lamp current (ICONST) having a constant magnitude; defining a commutation period having a duration TCOMM; defining a time base of original commutation moments, having fixed mutual intervals of 0.5*TCOMM; receiving data to be embedded in the light output; commutating the lamp current at commutation moments; wherein individual commutations are time-modulated in order to encode said received data. Preferably, a commutation moment is: either equal to an original commutation moment if there are no data to embed; or advanced over a modulation distance (Δ) with respect to the corresponding original commutation moment in order to encode data having a first value (“0”); or delayed over said modulation distance (Δ) with respect to the corresponding original commutation moment in order to encode data having a second value (“1”).

    摘要: A vehicle position measurement system (100) and method to determine the (relative) position of a vehicle (110) and an object (120) are proposed. The system comprises at least two light sources (131, 132) capable of emitting light and positioned at a predetermined distance (140) to each other. Furthermore the system comprises at least one detector (150/151, 152) capable of measuring the light emitted. The light emitted by the light sources comprises synchronized light source identification codes. The detector is arranged to determine the position of the vehicle (110) and object (120) on the basis of a phase-difference measurement between the light originating from the individual light sources (131, 132) and a comparison phase. The vehicle (110) may comprise the at least two light sources (131, 132) and the detector (151, 152), while the phase-difference is measured between light reflected from the object (120) and the comparison phase. Alternatively, the vehicle (110) may comprise the at least two light sources (131, 132) while the object (120) comprises the detector (150) and the detector is arranged to obtain the comparison phase from the light received from one of the light sources (131, 132). The object may be a vehicle.

    摘要: This invention relates to a method for processing light in a structure, such as a room or a part thereof, a vehicle, etc., where several light sources are arranged in the structure. The light sources emit light carrying individual codes. A camera is arranged in a camera position of the structure and registers images of spots of the light. The spots can be, “for instance, illuminated areas of a floor or the direct light images of the light sources. The individual codes are derived from the registered images and one or more properties, such as for instance light source position or light intensity, related to the associated light source, is determined. The method is performed by means of a lighting system having several light sources, a camera, and a signal processing apparatus. Typical applications for the invention are light source commissioning and real time foot-print measurements.
