20100110387 | METHOD OF CONTROLLING THE LIGHTING OF A ROOM IN ACCORDANCE WITH AN IMAGE PROJECTED ONTO A PROJECTION SURFACE - The invention describes a method of controlling a lighting of a room ( | 05-06-2010 |
20100171929 | DRY ERASABLE PROJECTION ARTICLE AND SYSTEM - A communication article and system comprising a writing member having a dry erasable front surface and a projection member is disclosed. The projection member includes an asymmetric optical diffuser that scatters light in a first direction with a first viewing angle A | 07-08-2010 |
20100208211 | AMBIENT LIGHTING FOR AN IMAGE DISPLAY - A system comprises means (PL; MI) for projecting an image light beam (ILB) on a projection area (PA) for display of an image (PI) on the projection area (PA), and means ( | 08-19-2010 |
20120013851 | FRONT PROJECTION SCREEN WITH HIGH CONTRAST - A light diffusing optical construction is disclosed. The optical construction includes an asymmetric optical diffuser that scatters light in a first direction with a first viewing angle A | 01-19-2012 |
20120224150 | FRONT PROJECTION SCREEN WITH HIGH CONTRAST - A light diffusing optical construction is disclosed. The optical construction includes a symmetric optical diffuser that scatters light in a first direction with a first viewing angle A | 09-06-2012 |
20140071403 | Servo Feedback Control Based on Designated Scanning Servo Beam in Scanning Beam Display Systems with Light-Emitting Screens - Scanning beam display systems that scan one servo beam and an excitation beam onto a screen that emits visible light under excitation of the light of the excitation beam and control optical alignment of the excitation beam based on positioning of the servo beam on the screen via a feedback control. | 03-13-2014 |
20140168610 | DECENTRALIZED INTELLIGENT NODAL LIGHTING SYSTEM - Techniques are disclosed for providing a decentralized intelligent nodal lighting system. The intelligent nodal lighting system may be controlled using a wireless protocol, such as Wi-Fi, and each lighting node in the system may have its own independent Wi-Fi address and may receive, store, and interpret commands from a wirelessly connected controller. Each intelligent light node may contain a CPU and memory for storing and interpreting commands from the controller to achieve a desired light color, intensity, or quality. In some embodiments, individual lighting nodes may be dynamically added or removed from the lighting system without interrupting the system's operation. | 06-19-2014 |
20150124224 | LIGHTING APPARATUS - A lighting apparatus is provided capable of emitting light for image projection and light for illumination at the same time. The lighting apparatus includes: an imaging element that converts incident light into light corresponding to an image and outputs the light; a projection lens through which the light is projected onto an object; a first optical path taken by light that is emitted from the projection lens via the imaging element; and a second optical path taken by light that is emitted without passing through the imaging element and the projection lens. | 05-07-2015 |
