| 20110273468 | Color Management Method for Color Representation with Self-Luminous Color Primaries - The present invention relates to a unique color management method for calibrating and characterizing a light mixing system comprising a set of primary light modules emitting self-luminous color primaries, which may be intimately mixed to produce a batch color that matches a standard color. The radiant output of each self-luminous color primary, or channel, is modulated by a setting a light controller to a Digital-to-Analog-Conversion (“DAC”) value. In the event that the radiant output of the color primary channels is non-linearly proportioned to the DAC input values, it is useful to employ an innovative “iterative best-fit” method of simultaneously calculating admixtures of light from all color primaries that match a standard color. Otherwise, a matrix method based on matrix algebra may also be used to create a batch color that matches a standard color. A best fit tristimulus value method or best fit minimum RMSD can be used in conjunction with these spectral color matching methods. In addition, an optical feedback method may be used to correct systematic drift of the individual color primary channels. | 11-10-2011 |
| 20110259897 | Food Server Assembly - A device for storing food and displaying food for service includes a base with a side wall extending upwardly from the base and a puck assembly removably disposed therein. The puck assembly has a generally flat plate surface on one side and a functional surface with a plurality of food receptacles formed thereon on the opposite side, a sealed cavity disposed between the plate surface and the functional surface, and a cooling substance disposed in the sealed cavity. A food tray is disposed proximate the puck assembly, and a lid shaped to alternatively fit on the top surface of the wall of the base and to fit on the external surface of the bottom of the base such that the base can nest in the lid. The device provides a multitude of optional arrangements of these elements to provide maximum flexibility to the user. | 10-27-2011 |
| 20110239874 | DRIVE SYSTEM - A drive unit that is movable between an unfired and a fired position. The drive unit comprises a handle member, a first drive gear having a first axis of rotation, and a second drive gear, engaged to the first drive gear at a mesh point, and having a second axis of rotation. The mesh point moves with respect to the axes of rotation as the handle member moves from the unfired position to the fired position. The drive unit drives an implement only when it is moved from the unfired position to the fired position. | 10-06-2011 |
| 20110112223 | Environmentally Friendly Colorant Compositions and Latex Paints/Coatings - The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present. | 05-12-2011 |
| 20100228511 | Method for managing metamerism of color merchandise - The present invention relates to a method for minimizing the effects of metamerism between a set of color standards (e.g., nitrocellulose lacquers) and inkjet printed color merchandise (e.g., paint chips) under a plurality of illuminants, including a balanced illuminant that emulates lighting conditions between cool (6500 K) and warm (2856 K) color temperatures. For each color standard, one selects an ink combination that best produces color merchandise having a minimal degree of metamerism. Innovatively, a combination of instrumental and visual tests is used to evaluate color difference for a set of color standards-color merchandise pairs under a plurality of illuminants. If a color standard-color merchandise pair fails either test then the ink combination may be adjusted. | 09-09-2010 |
| 20100225935 | Apparatus and method for dispensing color Merchandise - A methodology and apparatus provide the customers and other decision makers the ability to make decisions, such as purchase decisions and other selections, based solely on non-verbal and non-textual, non-symbolic or non-hieroglyphic prints on a substrate. | 09-09-2010 |
| 20090076786 | Method for Representing True Colors with Device-Dependent Colors on Surfaces and for Producing Paints and Coatings Matching the True Colors - A method for selecting paints is disclosed. This method includes the steps of selecting true paint colors, displaying device-dependent colors corresponding to the true paint colors in a simulated full size room and interacting with the buyers to change the displayed colors and select the desired colors. The method also includes the step of dispensing paints corresponding to the selected colors. The displayed colors are generated by multiple color and/or white LEDs to provide a wider gamut of displayable colors and more color saturation and chromatic. A full-size apparatus for displaying paint colors using device-dependent colors is also disclosed. | 03-19-2009 |
| 20090056561 | Combination Breading Tongs And Dipping Tool - A kitchen utensil includes a handle having a dipping utensil at one end and a gripping surface at a second end thereof. The dipping utensil includes a frame member defining an opening. A tong member is engaged to the handle and is rotatable with respect to the handle between open and closed positions. The tong includes an actuation lever at one end and a gripping surface on a second end, whereby the gripping surfaces of the handle and tong may cooperate to hold an item placed therebetween. | 03-05-2009 |
| 20080232101 | System for Representing True Colors with Device-Dependent Colors on Surfaces and for Producing Paints and Coatings Matching the True Colors - An apparatus for displaying paint colors using device-dependent colors is disclosed. The apparatus has a wall portion sized and dimensioned to be substantially similar to a full size wall, and the device-dependent colors have color coordinates that are substantially similar to the color coordinates of paint colors. Lights displaying the device-dependent colors are diffused before illuminating the wall portion. A method for selecting paints using device-dependent colors is also disclosed. | 09-25-2008 |
