Patent number: 10752022Abstract: Various embodiments concern inkjet printing systems designed for multilayer imaging with a high-gloss clear ink layer. More specifically, the inkjet printing systems are designed so that clear, curable inks are provided additional time to level out before being cured. The settling process enables the inkjet printing systems to produce multilayer images having high gloss values. For example, a bracket could be attached to a curing assembly that prevents radiation from striking a certain portion of the substrate onto which clear ink has recently been deposited. As another example, an inactive array of light-emitting diodes may be disposed in line with the print head(s) responsible for depositing clear ink. Moreover, various embodiments also allow for true multilayer printing of a color coat and a high-gloss clear coat in a single step (e.g., by arranging print heads into rows within a printer carriage).Type: GrantFiled: June 18, 2018Date of Patent: August 25, 2020Assignee: ELECTRONICS FOR IMAGING, INC.Inventors: Bruce Klemann, Joshua Mcgrath, John Duffield

Patent number: 10164316Abstract: A combining arrangement comprises a power combiner having at least four ports. A first match-dependent oscillator is connected to input power at a first frequency to a first input port of the power combiner. A second match-dependent oscillator is connected to input power at a second frequency to a second input port of the power combiner. A mismatch is connected to a third port of the power combiner. The power combiner is operative to combine power from the first and second oscillators and, when the first and second frequencies are different, to apply a fraction of the combined power to the mismatch. The mismatch reflects at least some of the fraction of the combined power to the first and second oscillators to phase and frequency lock their outputs. A fourth output port of the power combiner is connected to receive the combined power.Type: GrantFiled: March 28, 2016Date of Patent: December 25, 2018Assignee: TELEDYNE E2V (UK) LIMITEDInventors: Michael John Duffield, Craig Loch
