20100265421 | AUTOMATIC DARKENING FILTER APPARATUS AND METHOD - Herein is disclosed an automatic darkening filter apparatus comprising a shutter control system configured to cause a shutter to switch from a dark state to an intermediate state in response to a change from high intensity incident light to low intensity incident light being detected. The control system is further configured to maintain the shutter in the intermediate state for a period of time, unless during this period of time high intensity light is detected, in which case the control system causes the shutter to switch to the dark state. If, at the end of the period of time, high intensity light is not detected, the shutter is caused to switch from the intermediate state to a light state. | 10-21-2010 |
20120002121 | VARIABLE CONTRAST, WIDE VIEWING ANGLE LCD LIGHT-SWITCHING FILTER - A new concept of the LCD light-switching optical filter allowing for very high, electrically controlled, continuously variable light attenuation (up to ≧100,000) optimized/symmetrized for the light incidence along the normal to the LCD plane is proposed. The new LCD light-switching optical filter also exhibits very low light attenuation dependence for the oblique incidence of light within a limited cone of angles off the normal incidence direction in compliance with the international safety and quality regulation EN 379 for personal protection equipment. According to the invention the problem is solved by specific, novel modification of the general principle of highly twisted nematic LCDs, allowing for the adaptation of the light transmission/driving voltage characteristics to specific requirements of the driving electronics as well as “symmetrizing” the overall optical birefringent properties, which in turn results in a high degree of their angular compensation. | 01-05-2012 |

20130235286 | REAL-TIME AUTO-DIMMING SAFETY LENS DEVICE - A real-time auto-dimming safety lens device is adapted to assemble a dimmable lens, position various and fix a light sensor, controller and power supply, where the controller receives accurate visible-light illumination signals from a light sensor immediately and calculates the best transmittance or color of a dimmable lens, controls the transmittance or color of the environmental visible light penetrating the dimmable lens immediately and accurately so as to allow human's eyes to reach the farthest visible distance, be in the most comfortable state, and get the clearest environment scene. Therefore, a user can use the real-time auto-dimming safety lens device of the present invention to allow the user's eyes to reach the farthest visible distance, be in the most comfortable state, and get the clearest scene while the use locates in a particular environment (e.g. raining day, fogginess, snowfield). | 09-12-2013 |
20130278846 | ILLUMINATION SYSTEMS AND METHODS - This disclosure provides systems, methods, and apparatuses for providing illumination in, for example, a display device. One or more light emitters can emit light into a light guide plate that is configured to distribute the light across an array of display elements. A substantially etendue-preserving reflector between the light emitters and the light guide can at least partially collimate light propagating in a single plane of collimation. In some implementations, a lenticular film, or other optical elements, can be used to increase divergence of the light in a plane orthogonal to the plane of collimation. The light guide can include light extraction elements, which can be frusta-shaped features for turning light out of the light guide for illuminating the display. In some implementations, a flexible electrical interconnection circuit can be used to provide power and/or signals to the light emitters, thereby providing a flexible circuit illumination system. | 10-24-2013 |
