20100327755 | COLOR CONTROLLED LIGHT SOURCE AND A METHOD FOR CONTROLLING COLOR GENERATION IN A LIGHT SOURCE - This invention relates to a color controlled light source comprising a plurality of colored light elements, and a plurality of (filtered) photo detectors, having different spectral characteristics covering all or most of the total spectrum of the light elements. The (filtered) photo detectors detect the light output of the light source, and generate corresponding detection signals. The light source further has a color control unit for generating driving signals to the light elements on the basis of the detection signals and a predetermined target color point of the light output of the light source, and a modulator for individual signature modulation of the driving signal to each one of said light elements. A corresponding demodulator is provided for demodulation of the detection signals and extraction, from each detection signal, of actual values of the light outputs of the light elements. The color control unit has means for determining the spectral output of each light element on basis of the actual values, means for determining an actual color point from said spectral outputs of all light elements, and means for comparing said target color point with said actual color point and, if there is a difference, adjusting said driving signals in order to minimize the difference. | 12-30-2010 |
20110174976 | SPECTRAL DETECTOR - The invention relates to a method for manufacturing a spectral detector including a photo detector array and cholesteric liquid crystal material for measuring properties of light over portions of the electromagnetic spectrum.

20120106290 | STATIC MIXER COMPRISING A STATIC MIXING ELEMENT, METHOD OF MIXING A FLUID IN A CONDUIT AND A FORMULA FOR DESIGNING SUCH A STATIC MIXING ELEMENT - Using the Mapping Method different designs of SMX motionless mixers are analyzed and optimized. The three design parameters that constitute a specific SMX design are: the number of cross-bars over the width of channel, Nx, the number of parallel cross-bars per element, Np, and the angle between opposite cross-bars θ. Optimizing Nx, somewhat surprisingly reveals that in the standard design with Np=3, Nx=6 is the optimum using both energy efficiency as well as compactness as criteria. Increasing Nx results in under-stretching and decreasing Nx leads to over-stretching of the interface. Increasing Np makes interfacial stretching more effective by co-operating vortices. Comparing realized to optimal stretching, we find the optimum series for all possible SMX(n) designs to obey the universal design rule Np=(⅔)Nx−1, for Nx=3, 6, 9, 12, . . . | 05-03-2012 |

20090023412 | FM RADIO RECEIVER - A diversity FM radio receiver comprises two tuners for simultaneously tuning to the same FM channel. To avoid disturbances between the local oscillator signals of the tuners and to be able to use standard IF filters, one of the tuners operate with high-side LO injection and the other tuner operates with low-side LO-injection. To equalize the frequencies of the signals to be subjected to the diversity operation the two IF-signals of the tuners are fed to complex mixers with oppositely rotating phases. | 01-22-2009 |
