20120306030 | BALANCING A MICROELECTROMECHANICAL SYSTEM - A method of balancing a microelectromechanical system comprises determining if a microelectromechanical system is balanced in a plurality of orthogonal dimensions, and if the microelectromechanical system is not balanced, selectively depositing a first volume of jettable material on a portion of the microelectromechanical system to balance the microelectromechanical system in the plurality of orthogonal dimensions. A jettable material for balancing a microelectromechanical system comprises a vehicle, and a dispersion of nano-particles within the vehicle, in which the total mass of jettable material deposited on the microelectromechanical system is equal to the weight percentage of nano-particles dispersed within the vehicle multiplied by the mass of jettable material deposited on the microelectromechanical system. A microelectromechanical system comprises a number of unbalanced structures, and a number of droplets of jettable material disposed on the unbalanced structures, in which the droplets of jettable material balance the unbalanced structures in a plurality of orthogonal dimensions. | 12-06-2012 |
20130278928 | SURFACE ENHANCED RAMAN SPECTROSCOPY CALIBRATION CURVE GENERATING SYSTEMS - A surface enhanced Raman spectroscopy calibration curve generating system includes a SERS sensor, which includes a substrate and a plurality of sensing members formed on the substrate. Each of the sensing members includes a plurality of SERS signal amplifying structures. An inkjet dispensing device is to dispense different concentrations of a solution including a known analyte of interest onto the respective sensing members to form a concentration dependent array. A Raman spectrometer is to interrogate the concentration dependent array. A processor is operatively connected to each of the inkjet dispensing device and the Raman spectrometer. Computer-readable instructions are embedded on a non-transitory, tangible computer-readable medium and are executable by the processor. The computer-readable instructions are to automatically generate an intensity profile as a function of concentration for the concentration dependent array. | 10-24-2013 |

20160032120 | COLORANT - A colorant for a printing apparatus is described. The colorant has a first component and a second component. The first component is configured to reflect radiation having a first set of wavelengths when the colorant is arranged on a substrate. The second component is configured to absorb radiation having a second set of wavelengths and emit radiation having a third set of wavelengths when the colorant is arranged on the substrate, the first and third set of wavelengths having at least one common wavelength. | 02-04-2016 |
20160034795 | COLOR MAPPING - A method for generating a color mapping for a printing apparatus is described. The printing apparatus includes a plurality of colorants including a first colorant configured to reflect radiation having a first set of wavelengths and a second colorant configured to absorb radiation having a second set of wavelengths and emit radiation having a third set of wavelengths.

20160034796 | SPECTRAL PRINT CONTROL BASED ON SPECIFIC SPECTRAL RANGES OF COLORANTS - Certain methods and systems are described that allow the spectral control of a print output. A plurality of colorants are used where one or more colorants contain nanoparticles. Each colorants has a specified spectral range corresponding to the constituent nanoparticles. To print with these colorants a spectral separation may be used that maps an input color with associated spectral information or direct spectral information to print control data, the print control data having defined values for depositions with each combination of the colorants. The spectral separation may be constructed by characterizing a set of spectral Neugebauer primaries for the plurality of colorants. | 02-04-2016 |
20160037017 | ENCODING DATA IN AN IMAGE - Certain methods and systems are described for encoding data in an image. According to an example, a set of metamers under a first set of conditions may be determined that vary under a second set of conditions. These may be used to generate a set of color mappings for a sampled color value, each color mapping being used for a different data value in the data. As such the data values may be detectable when the image is observed under the second set of conditions but not detectable when the image is observed under the first set of conditions. | 02-04-2016 |
