  • Patent number: 10876261
    Abstract: Systems and methods are provided for use with a thermoplastic road marking system (e.g., paint truck). The systems and methods control an insertion or replenishment rate of unmelted thermoplastic paint feed stock into a thermoplastic melter based, at least in part, on the rate that thermoplastic melt is being applied to a marking surface. By substantially matching the replenishment rate into the thermoplastic melter with the application rate, thermal variance within the thermoplastic melter is reduced, which improves the consistency of marking lines applied to surfaces.

  • Patent number: 10811324
    Abstract: An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.
