摘要： A method for detecting the presence of a television signal embedded in a received signal including the television signal and noise is disclosed. Either first-order or second order cyclostationary property of the signals may be used for their detection. When the first-order cyclostationary property is used, the following method is used, the method comprising the steps of upsampling the received signal by a factor of N, performing a synchronous averaging of a set of M segments of the upsampled received signal, performing an autocorrelation of the signal; and detecting the presence of peaks in the output of the autocorrelation function. When the second order cyclostationary property of the signal is used, the method comprising the steps of delaying the received signal by a fixed delay (symbol time), multiplying the received signal with the delayed version, looking for a tone (single frequency) in the output.

摘要： The invention relates to a control device (10) for use in an ambient light control system (20) for controlling ambient light entering a space (1) through an opening (2). An ambient light prediction unit (11) provides ambient light prediction values, which are predictions of an ambient light property at the opening (2). An ambient light adjusting unit (12) provides, at different ambient light adjusting time points, an ambient light adjusting signal depending on the ambient light prediction values for an upcoming ambient light prediction time period. The ambient light adjusting signal is adapted for use by an ambient light modifying element (22) for modifying the entering of ambient light into the space (1) through the opening (2). By taking the predicted ambient light conditions at the opening (2) into account, necessary adjustments can be made at temporally spaced ambient light adjusting time points, resulting in fewer disturbances of the users.

摘要： This invention relates to a method and system for controlling light distribution in a space including multiple installed light sources and an external light source. The luminance level of light from said light sources is measured at different measuring areas within the space. A weighed luminance level is determined for each of the measuring areas based on the measured luminance levels, where the weighted luminance level indicates the contribution from the light sources to the measured luminance level at the different measuring areas. This weighed luminance level is used as a tuning parameter for tuning the emitted light at the installed light sources such that the weighed luminance level at each of the different measuring areas substantially matches a pre-defined target luminance level at the different measuring areas.
