  • Patent number: 11043946
    Abstract: A method for adjusting a skew between a second clock signal and a first clock signal is provided. The second clock signal has been propagated from a first clock source through a second clock tree. The second clock tree comprises a programmable delay line that induces a delay. The method comprises at least one iteration of: measuring a skew between the second clock signal and the first clock signal, comparing an absolute difference of the measured skew and a sum of delay changes initiated in a time window preceding the measurement with a target skew, and initiating a delay change of the delay induced by the programmable delay line in the second clock tree depending on a result of the comparison.

  • Patent number: 11032885
    Abstract: A single solid state luminaire product is field-configurable to a plurality of discrete coordinated color temperature (CCT) and/or maximum luminosity settings. A field-actuated control circuit may control a current ratio control circuit, which directs drive current from a power supply to selected ones, or in selected ratios to multiple ones, of heterogeneous LED strings. Additionally or alternatively the control circuit may control the power supply, to select an overall maximum level of drive current, which determines the maximum luminosity of the luminaire. Inputs for CCT and/or maximum luminosity are input to the field-actuated control circuit prior to the luminaire being removed from its product packaging. Embodiments allow a distributor to order and stock a large inventory of substantially identical luminaires from the manufacturer, yet still offer customers a variety of different CCT and/or maximum luminosity products.
