Abstract: A system and method for visually enhancing an original image of an eye includes a visualization module. A controller is configured to convert an output of the visualization module to a first pixel cloud in a first color space and map the first pixel cloud to a second pixel cloud in a second color space. The method includes identifying at least one selected zone in the second color space. The controller is configured to move the selected zone from an original location to a modified location in the second color space. The second pixel cloud is updated to obtain a modified second pixel cloud, which is transformed into a third pixel cloud in the first color space. An enhanced image is formed based in part on the modified second pixel cloud and provides selective visual enhancement in the selected zone without affecting contrast in a remainder of the original image.

Abstract: High frequency power inductor material having first and second opposed major surfaces, comprising a thermosetting binder and a plurality of multilayered flakes dispersed in the high temperature binder, the multilayered flakes comprising at least two layer pairs, wherein each layer pair comprises a ferromagnetic layer and a dielectric electrical isolation layer so that the ferromagnetic layers are electrically isolated from each other by dielectric layers, and wherein the multilayered flakes are substantially aligned parallel to the first and second major surfaces such that they do not provide an electrically continuous path over a range of greater than 0.5 mm. Exemplary high frequency power inductor materials described herein are useful, for example, as a power inductor in Point of Load converters, low profile inductors for inductive—capacitive (LC) filters (e.g.
