20080273237 | Robust Multi Particle System For Color Electrophoretic Displays With Very Low Driving Voltages Comprising a Low Amount of Electrolytes - An electrophoretic dispersion with at least two particle species is proposed in which a minimal number (and concentration) of free compounds is present in solution. All chemicals needed to color and stabilize the pigment particles are preferably covalently attached to or within the particles. This enhances the robustness of the system and minimizes the conductivity of the dispersion so that the driving voltage for an electrophoretic display is reduced. | 11-06-2008 |

20120095534 | ILLUMINATION DEVICE AND METHOD FOR REDUCING SLEEP INERTIA OR CONTROLLING ALERTNESS - The invention relates to a method and an illumination device arranged for reducing sleep inertia and/or for controlling alertness of a human being. The illumination device is arranged for reducing sleep inertia and/or controlling alertness by light radiation. The illumination device comprises one or more light sources for generating a first illumination output and a second illumination output. The first illumination output comprises light with a dominant wavelength in the range of 590-770 nm. The second illumination output comprises light with a dominant wavelength in the range of 400-560 nm Thus, colored light is used. Alternatively, the first illumination output comprises white light with a color temperature below 4100 K, i.e. warm white light. The second color temperature then comprises white light with a color temperature above 4900 K. The illumination device comprises a controller configured for controlling the one or more light sources to expose said eye of said human being to the first illumination output during a first time interval and to the second illumination output during a second time interval. The second time interval terminates at a later point in time than the first time interval. The time intervals are selected such that at least one of the first and second time interval is less than 60 seconds. | 04-19-2012 |

20120101556 | COLOR LIGHTING SYSTEM TO INFLUENCE PERCEPTION OF AMBIENT TEMPERATURE - A basic idea of the invention is to categorize color of light into groups on the basis of dominant wavelength. After the colors have been categorized into different groups, a particular group of colors may be selected on the basis of a predetermined criterion, one criterion being that an individual is to perceive the ambient temperature as higher than it actually is, while another criterion may be that the individual is to perceive the ambient temperature as lower than it actually is. Thereafter, a control signal is generated for controlling the dominant wavelength of light emitted from at least one light source in accordance with the selected group of colors. Finally, the generated control signal is transmitted to the light source(s) to be controlled, for emitting light of the selected group of colors, thereby influencing the thermoregulation of an individual being exposed to the light of the selected group of colors on the basis of the predetermined criterion. The present invention is advantageous, in that colored lighting is employed for changing an individual's perception of ambient temperature, which enables energy savings for heating and air conditioning systems. Using a lighting control device for varying color of light results in a flexible solution since the device easily facilitates changing to an environment that is perceived as warmer or as cooler than the actual room temperature. | 04-26-2012 |

20140288359 | COLOR LIGHTING SYSTEM TO INFLUENCE PERCEPTION OF AMBIENT TEMPERATURE - A lighting control device for influencing thermoregulation of a vertebrate is disclosed. In one example, the lighting control device configured to select, on the basis of a predetermined criterion, a particular group of colors of groups having been categorized into groups on the basis of dominant wavelength, where each group of colors is arranged to influence a vertebrate's thermoregulation in a particular manner, and configured to generate a control signal for controlling the dominant wavelength of light emitted from at least one light source in accordance with the selected group of colors. The lighting control device is configured to transmit the generated control signal to said at least one light source for said at least one light source to emit light of the selected group of colors, thereby influencing the thermoregulation of the vertebrate being exposed to the light on the basis of said predetermined criterion. | 09-25-2014 |
