Abstract: Some embodiments herein are directed to head-mounted Virtual Retina Display (VRD) systems with actuated reflective pupil steering. The display systems include a projection system for generating image content and an actuated reflective optical architecture, which may be part of an optical combiner, that reflects light from the projection system into the user's eyes. The display systems are configured to track the position of a user's eyes and to actuate the reflective optical architecture to change the direction of reflected light so that the reflected light is directed into the user's eyes. The VRDs described herein may be highly efficient, and may have improved size, weight, and luminance such that they are capable of all-day, everyday use.

Abstract: It is described as a package for educational and creative manual craft work using Campeche wax as an adherent link between a yarn or other material and a base having printed forms; to place, fix and delimit color, textures, volume and other materials within the limits of the forms.
