20100123407 | LIGHT COLLECTION SYSTEM FOR AN ELECTRODELESS RF PLASMA LAMP - An electrodeless plasma lamp and a method of generating light are provided. The plasma lamp may comprise a power source to provide radio frequency (RF) power and a lamp body to receive the RF power. The lamp body may include a dielectric material having a relative permittivity greater than 2. A bulb is provided that contains a fill that forms a light emitting plasma when the RF power is coupled to the fill. Collection optics is provided to direct the light along an optical path to an aperture, wherein the optical path includes at least one reflective surface and at least two refractive surfaces. | 05-20-2010 |
20100165306 | BEAM PROJECTION SYSTEMS AND METHODS - Throughput efficiency of an optical system is enhanced by using a directional light source coupled to a non-imaging optical element matched to a size and acceptance angle of an imaging lens. In various embodiments, a beam projection system and accompanying method are described that include a lamp body formed from a dielectric material. A bulb, placed adjacent to the lamp body, has a fill that forms a plasma when RF power is coupled to the fill from the lamp body. An optical train is optically coupled to the bulb to transform light generated by the plasma. The optical train includes a non-imaging optical element, an aperture, and at least one imaging lens element. | 07-01-2010 |

20130301014 | Wide Field of View Substrate Guided Relay - A substrate guided relay includes multiple output couplers and multiple light valves positioned between the substrate and the output couplers. The number of light valves may be equal to the number of output couplers, or may be more or less than the number of output couplers. The light valves may be enabled sequentially, or may be enabled based on the position of a user's eye. The light valves may include liquid crystal material. | 11-14-2013 |
20140036374 | Bifocal Head-up Display System - A bifocal head-up display system includes a projector, at least one projection surface in an intermediate image plane, and relay optics to direct a display image to a reflector in a vehicle operator's field of view. The display image includes two image portions focused at different distances from the vehicle operator. A first image portion focused at a first distance may include information related to vehicle operation, and a second image portion focused at a second distance may include to information related to extra-vehicular objects. | 02-06-2014 |
20140118704 | Mobile Device, Case and Attachment with Retractable Optic - A retractable optic conditionally redirects an image from a scanning laser projector. The retractable optic may be coupled to a mobile device, a mobile device case, or may be part of an attachment. The retractable optic includes a reflective surface that has a free-form shape defined by a polynomial that is a function of two independent, transverse coordinate variables. | 05-01-2014 |
