  • Patent number: 8968985
    Abstract: The presently described embodiments use a printing process, e.g. a wax printing technique, to pattern a mask layer (such as a soldermask layer) of, for example, a printed circuit. Substantially all other conventional processes in developing soldermask and exposure processes can be maintained. According to the presently described embodiments, each printed circuit will have a unique pattern that matches uniform and non-uniform runout. In one form, the pattern is comprised of wax single drops having a specified gap to make the process transparent to the current industry practice. Furthermore, the single drops can be used for both large and small areas without any development time differences. In at least one form, the wax pattern and the soldermask in the gap are removed during development.

  • Patent number: 8936954
    Abstract: A low-cost integrated reflector and heat spreader for high-density high power solid-state (e.g., LED) lighting arrays includes a base structure onto which is applied a sacrificial material. A relatively thick thermal spray coating is applied over the base structure and sacrificial material. The sacrificial material is removed. A channel(s) is thereby provided within the thermal spray coating layer and in physical contact with the base structure. The channel may be filled with a cooling fluid. A pulsating heat pipe heat spreader may thereby be provided. A reflective material may be provided either over another surface of the base structure or alternatively over the thermal spray coating layer to provide a surface for reflecting and directing light emitted from a solid state light source that may be secured to the integrated reflector and heat spreader.

  • Patent number: 8919939
    Abstract: Approaches to remove objects from ink in an ink jet printer are described. An object separator for an ink jet printer includes one or more inlets configured to allow passage of ink that includes objects such as bubbles and particles into the object separator. The object separator has a number of stacked plates. Some of the plates have curved channels which are connected through other plates that include vias. The plates are arranged to form at least one cyclonic flow generator, the cyclonic flow generator configured to focus the objects into one or more focused flow streams. The object separator includes one or more object outlets that allow objects to exit the object separator and at least one ink outlet that allows the ink to exit the object separator.

  • Publication number: 20140168327
    Abstract: Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using at least one temperature dependent element disposed along an ink flow path. The temperature dependent element is configured to change shape responsive to a change in ink temperature. The change in shape causes a volumetric change in a portion of the ink flow channel.

  • Publication number: 20140168310
    Abstract: Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using a membrane disposed along an ink flow path. The membrane includes first and second component membranes having first and second coefficients of thermal expansion. The membrane is configured to, in response to a change in ink temperature, mechanically displace as a function of temperature due to a difference in the thermal coefficients of expansion of the first and second component membranes. The mechanical displacement of the membrane causes a volumetric change in a portion of the ink flow path.

  • Patent number: 8690302
    Abstract: Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using one or more separator elements configured to separate bubbles of a vapor from ink. Each separator element includes wicking features having dimensions sufficient to allow capillary movement of the ink in the wicking features and to substantially exclude the bubbles from the wicking features. One or more inlets allow passage of the ink that includes the bubbles into the separator element. At least one vapor outlet allows vapor that has been separated from the ink to exit from the separator element. The ink exits from the separator element thought one or more ink outlets.

  • Patent number: 8506063
    Abstract: A print head assembly for an ink jet printer includes an ink flow path configured to allow passage of a phase-change ink. A pressure unit is fluidically coupled to the ink flow path to apply a pressure to the ink. The applied pressure is controlled by a control unit during a time that the ink in the ink flow path is undergoing a phase change. During the phase change, a portion of the ink in a first region of the ink flow path is in liquid phase and another portion of the ink in another region of the ink flow path is in solid phase. A constant or variable pressure can be applied at least to the liquid phase portion of the ink during a phase transition from a liquid phase to a solid phase or from a solid phase to a liquid phase.
