  • Publication number: 20240136721
    Abstract: A multi-antenna structure may include a monopole and a first antenna array connected to the monopole at a first location via a first mounting apparatus and including a first cellular antenna and a first radio unit. The structure may also include a second antenna array connected to the monopole at a second location via a second mounting apparatus, with a second cellular antenna and a second radio unit. The structure may include a first set of fronds arranged about an outer surface of the monopole, forming a first respective angle with the monopole and configured to obscure the first antenna array from view. The structure may include a second set of fronds arranged about the outer surface of the monopole, each of the second set of fronds forming second respective angle with the monopole. The second set of fronds may be configured to obscure the second antenna array from view.

  • Patent number: 10752022
    Abstract: 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).

  • Patent number: 10164316
    Abstract: 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.
