  • First drop dissimilarity in drop-on-demand inkjet devices and methods for its correction
    Patent number: 10744759
    Abstract: A number of methods may be utilized to correct for the first drop dissimilarity in drop-on-demand inkjet devices. Various collection processes, mass calculations and timing manipulation may be utilized to correct the first drop dissimilarity problem.
    Type: Grant
    Filed: June 29, 2010
    Date of Patent: August 18, 2020
    Assignee: Cardinal Health Switzerland 515 GmbH
    Inventors: William J. Baldy, Jr., Amin Famili, Saurabh A. Palkar
  • Method for improving drop morphology of drops ejected from an injet device
    Patent number: 8708442
    Abstract: A method for improving the morphology of drops ejected from inkjet dispensers results in a more accurate and repeatable process. The method involves shifting the dwell time from one corresponding to the first harmonic of the dispenser to a higher harmonic, for example, the third harmonic.
    Type: Grant
    Filed: April 27, 2011
    Date of Patent: April 29, 2014
    Inventors: William J. Baldy, Jr., Amin Famili, Saurabh A. Palkar
  • Quantitation and analysis of droplets ejected from an inkjet device
    Patent number: 8678539
    Abstract: A method for determining either the mass of one or more drops dispensed from an inkjet dispensing device or the concentration of dissolved solutes form one or more drops of a liquid of interest dispensed from an inkjet dispensing device utilizes UV visible spectroscopy. The UV absorption spectra of the constituents of the solution may be compared to predetermined calibration curves to accurately determine mass and concentrations of a single drop.

  • Sub-threshold voltage priming of inkjet devices to minimize first drop dissimilarity in drop on demand mode
    Patent number: 8333451
    Abstract: The establishment of a stable acoustic environment within the individual channels of an inkjet printing device functions to allow the inkjet printing device to precisely deposit the same amount of a particular substance at one or more locations on an object. This is particularly relevant when the inkjet printing device is operated in the on-demand mode of operation.
