A vital sign detection system comprises a camera () configured to acquire image frames from an examination zone (). A signal processor () derives vital sign information from the acquired image frames. An illumination controller () controls illumination of the examination zone, generates temporal modulations of the illumination and synchronise the camera frame rate with the modulated illumination. The vital sign detection system of the invention achieves to increase the dynamic range and hence also the signal-to-noise ratio of the vital sign signal.

The present invention relates to a device () for estimating an average value of an inductor current for switched-mode power converters (), the device () comprising: a sensor (), which is configured to measure an inductor voltage (v_L) and an inductor current (i_L); a ripple-suppressor (), which is configured to provide an estimated inductor current ripple (EIR) based on the measured inductor voltage (v_L); and a current-corrector (), which is configured to provide a corrected inductor current (i_Lc) based on the estimated inductor current ripple (EIR) and the measured inductor current (i_L).

Estimating an average value of an inductor current for switched-mode power converters

Pre-conditioners (or line-conditioners) are used to convert electrical power having first characteristics into electrical power having second characteristics. For example, a pre-conditioner may connect electrical equipment forming a load, which requiring only a conventional mains supply level to a utility three-phase supply. This means that the power components of the load may be de-rated, making the load electrical equipment cheaper. Such circuits may be further improved. Components in the down-converter itself still need to be rated to interface with the higher voltage. An approach is proposed in which two interleaved down-converters () can be used to supply voltages. An energy recovery element () connects snubbers of the interleaved down-converters, thus enabling some de-rating of the pre-conditioner circuitry.
