Abstract:
Technologies are generally described to display of an Augmented Reality (AR) image using a micromirror on an eyeglass. In some examples, AR data may be received at a controller coupled to a laser transmitter positioned on a surface of a frame of the eyeglass. The laser transmitter may transmit a laser signal modulated by the received AR data onto the micromirror positioned on, preferably, a proximal surface of a lens of the eyeglass. Concurrently, an electrical signal may be transmitted to a base of the micromirror causing the micromirror to oscillate in correlation with an intensity of the laser signal such that the AR image is created on a retina. In another embodiment, the laser signal modulated by the received AR data may be reflected from a plane mirror positioned on the proximal surface of the frame, forward to the laser transmitter, to transmit the laser signal onto the micromirror.
Abstract:
Lighting devices are disclosed having a light-transmissive resin sheet and one or more light sources disposed within the light-emitting resin sheet. The light sources may, in some embodiments, be oriented so that a large portion of light emitted from the light sources exhibits total internal reflection within the light-transmissive resin sheet and is trapped inside the sheet. This total internal reflection may, for example, advantageously provide a more uniform light emitted from the lighting device when scattered from objects inside the sheet. Methods of making and using the lighting device are also disclosed

Abstract:
Technologies are generally described for an extrusion nozzle of a 3D printing system that allows deposition and rapid solidification of a resin layer on a non-uniform substrate surface in order to form a 3D printed article of various shape and size. The extrusion nozzle may include a center tube that facilitates a flow of resin through the center tube to deposit the resin layer on the substrate surface. A second tube may surround the center tube such that a first annular space between the center tube and the second tube is vacuum-insulated to maintain the resin at a constant temperature as it flows through the center tube and is deposited. A third tube may surround the second tube, and guide a deposition of a cooling gas onto the deposited resin layer through a second annular space between the second tube and the third tube to rapidly solidify the resin layer.
Abstract:
In some examples, a system may be configured to generate a holographic image of an object. The system may include a holographic recording medium and a fiber laser. The fiber laser may be configured to generate a first output beam at a first end of an optical fiber of the fiber laser. The fiber laser may be further configured to generate a second output beam at a second end of the optical fiber. The first output beam may be configured to be directed toward the object as an illumination beam for the holographic image of the object. Additionally, the second output beam may be configured to be directed toward the holographic recording medium as a reference beam for the holographic image.
