Abstract: Several current sensing techniques are described that may be used to obtain an accurate current signal, which may help to achieve the best performance with a trans-inductor voltage regulator (TLVR) topology. The techniques may have the coupling effect from the secondary side included, so the current sensing signal is accurate for the regulation and other functions related to the current signal. The current sensing techniques may have more accurate gain and phase information in the middle frequency and high frequency ranges. The coupling effect from the secondary side may be well represented in the current sensing signal. The advantages of TLVR topology may be enhanced with accurate current information.

Abstract: A self-contained, handheld probe for measuring at least one parameter of skin condition, has one or more light sources that may be used to project light upon the skin. The light projected is of a selected wavelength known to generate a specific fluorescence that is indicative of the skin parameter of interest in accordance with a known correlation. To produce the proper excitation light, a light source generating that wavelength is used or a broader spectrum of light is selectively filtered to pass the wavelength of interest. Lenses, fiber optic elements or waveguides may be employed to project the light onto the skin at a specific location and/or to deliver the skin response to a light detector, which measures the light signal from the skin. and generates an output signal indicative of the value of the at least one parameter. The probe may be used to measure skin age, photodamage and/or proliferation.
