Abstract: A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.

Abstract: A wearable display system includes a light projection system having one or more emissive microdisplays, e.g., micro-LED displays. The light projection system projects time-multiplexed left-eye and right-eye images, which pass through an optical router having a polarizer and a switchable polarization rotator. The optical router is synchronized with the generation of images by the light projection system to impart a first polarization to left-eye images and a second different polarization to right-eye images. Light of the first polarization is incoupled into an eyepiece having one or more waveguides for outputting light to one of the left and right eyes, while light of the second polarization may be incoupled into another eyepiece having one or more waveguides for outputting light to the other of the left and right eyes. Each eyepiece may output incoupled light with variable amounts of wavefront divergence, to elicit different accommodation responses from the user's eyes.

Abstract: A method of instantly reducing the appearance of wrinkles and skin imperfections while smoothing the skin, which comprises applying a cosmetic composition comprising a fractal particle based gel.

Abstract: A cosmetic powder composition is provided for retarding moisture loss from skin to which the powder is applied. The cosmetic powder composition has a moisturizer coated filler powder and a time release moisturizing agent. The invention also provides a method for preparing such a cosmetic powder composition that retards moisture loss when applied to the skin and for the use of such cosmetic powder composition to inhibit moisture loss when applied to the skin.

Abstract: There is disclosed a method of imparting a cosmetic or therapeutic benefit to a topical surface. The method has the steps of a) providing a polymer powder having a plurality of substantially nonporous polymer particles with a number average particles size of about 0.1 to about 0.5 microns in diameter; b) providing a liquid cosmetic or therapeutic composition in the form selected from the group consisting of a solution, dispersion, suspension, and an emulsion in which the liquid composition has one or more cosmetic or therapeutic actives therein and is metastable; c) contacting the polymer powder with the liquid composition so that the liquid composition is entrained so as to form an impregnated powder; and d) rubbing the impregnated powder on the topical surface such that at least a substantial portion of the liquid composition is released from the impregnated powder at the topical surface. There are other methods and processes disclosed.
