Abstract: A method for forming a conductive circuit on a substantially non-conductive substrate includes indenting a major surface of a substrate with a plurality of features, plating the major surface and the indentations formed with a conductive layer, and removing a portion of the conductive layer leaving at least one of the plurality of the indentations filled with conductive material separated from at least one other of the plurality of the indentations filled with conductive material separated by non-conductive material. An electrical device formed includes a sheet of insulative material having grooves therein. The sheet of insulative material has a first planar surface, and a second planar surface. A conductive material is positioned within the grooves. The conductive material within the grooves forms electrical traces in the electrical device. The conductive material within the grooves fills the groove and includes a surface coplanar with at least one of the first planar surface or the second planar surface.

Abstract: An optical projection system includes an image source that is configured to generate an array of image pixels. A lens assembly is configured to project the array of image pixels onto a hemispherical surface at a projection angle greater than 180°. The lens assembly may include a wide-angle lens assembly and an image relay lens assembly that is configured to reduce dispersion in the array of image pixels between the image source and the wide-angle lens assembly. The wide-angle lens assembly may include a meniscus lens assembly and a wavefront shaping lens assembly. The lens assembly may be further configured to project the array of image pixels onto the hemispherical surface such that there is a constant angular separation between adjacent image pixels.
