| 20100208236 | METHOD FOR DETERMINING THE POSITION OF AN OBJECT IN A STRUCTURE - This invention relates to a method for determining the position of an object in a structure. The object receives modulated light waves from a plurality of light sources, which are arranged in the structure. The modulation is individually coded, and the position of the light sources in the structure is known. The modulation signals are synchronized, and thereby it is possible to determine the position of the object on basis of measuring the phase difference between the phase of each received modulated light wave and a comparison phase. The phase difference is used for distance calculations, which in turn give the position of the object. | 08-19-2010 |

| 20100301776 | METHOD AND A SYSTEM FOR CONTROLLING A LIGHTING SYSTEM - The present invention relates to a location commissioning method for a lighting system, which comprises several lighting arrangements. Thus, an illuminated position, of for example a room, is selected for the performing the commissioning, which is then associated with that position. This commissioning is called Luxissioning™. The position is assigned a position id, and the light at the position is measured. Light data associated with each one of the lighting arrangements is derived from the measured light, and the light data is associated with the position id. Light transfer data is determined on basis of the light data and current drive data for the lighting arrangements and stored in a light effect setting array for the position id. A light effect setting method is also present, where there is requested a selected light effect at a selected position. For each such request data comprising a position id and a target light effect setting associated with the position is received. The associated initial light effect setting array is derived, for example by retrieving a stored one. Required drive data for the relevant light arrangements, for obtaining the target light effect setting, is determined by means of the light transfer data held in the array, and adjustments are made accordingly, if necessary. Devices and systems for performing the above methods are also addressed by this invention. | 12-02-2010 |
