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: Optically transparent reflectarray articles and methods of making and using the same are provided. The reflectarray article includes a frequency selective surface (FSS) layer and a ground plane layer disposed on opposite sides of a dielectric substrate. The FSS layer includes a pattern of wire-like resonating metallic elements configured to reflect incident mmWaves, and the ground plane layer includes a pattern of metal-based conductor mesh to provide conductivity and high visible light transmittance.

Abstract: A magnetic film includes a plurality of magnetically permeable particles dispersed between opposing first and second major surfaces of the magnetic film. The first and second major surfaces are spaced apart a distance D. The particles are agglomerated so as to form a plurality of substantially continuous layers of particles generally extending along orthogonal first and second directions and arranged along a third direction. Each substantially continuous layer of particles has a length L along the first direction from a first to an opposing second edge of the magnetic film and a width W along the second direction extending from the first to the second major surface. L/D≥100.

Abstract: A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by a network of interconnected gaps. The interconnected gaps are at least partially filled with a thermoset dielectric material. The network of interconnected gaps at least partially suppresses electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.

Abstract: A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by gaps. At least some of the electrically-conductive soft magnetic islands have an outer insulating oxidized layer that electrically insulates them from adjacent electrically-conductive soft magnetic islands. The gaps at least partially suppress electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.

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., for global system for mobile communication (GSM) pulse noise suppression in cellular phone speakers), or other applications wherein compact, inductive elements are required on a circuit board.
