An LED-based light source for generating light having a selected dominant wavelength \u03bbds comprises a package housing a plurality of LEDs consisting of LEDs from first and second wavelength bins. As a result, intrinsic camera parameters, camera positions on the metric space and the structure of the building are restored. The sensing element includes an inductor. One aspect of the present disclosure is a process for making a water dispersible policosanol cyclodextrin complex for animal ingestion. The third transistor is connected to a drain of the first transistor through a first node.
