  • Patent number: 9754704
    Abstract: A method of making a thin-film multi-layer micro-wire structure includes providing a substrate and a layer on the substrate with one or more micro-channels having a width less than or equal to 20 microns. A conductive material including silver nano-particles and having a percent ratio of silver that is greater than or equal to 40% by weight is located in the micro-channels and cured to form an electrically conductive micro-wire. The electrically conductive micro-wire has a width less than or equal to 20 microns and a depth less than or equal to 20 microns. Each micro-wire is electrolessly plated to form a plated layer located at least partially within each micro-channel between the micro-wire and the layer surface in electrical contact with the micro-wire. The plated layer has a thickness less than a thickness of the micro-wire so that the micro-wire and plated layer form the thin-film multi-layer micro-wire.

  • Patent number: 7261389
    Abstract: A thermally-conductive fluid ejector carriage device is used to dissipate heat from a thermal fluid ejector module in a fluid ejection device. The thermally-conductive fluid ejector carriage device is molded from a polymer, or a polymer material including at least one thermally-conductive filler material. The thermal fluid ejector module is brought into contact with the thermally-conducting polymer carriage to dissipate heat. The polymer can be a highly thermally-conductive polymer. A method of manufacturing the thermally-conductive polymer carriage includes molding the carriage at least partially from a polymer that includes thermally-conductive filler materials, and contacting the thermally-conducting polymer carriage with the fluid ejector module. A method for use of the thermally-conductive fluid ejector carriage device includes establishing a heat flow path from the fluid ejector module to ambient air through the thermally-conductive fluid ejector carriage device.

  • Patent number: 7192116
    Abstract: A system, method and structures for dissipating heat away from a thermal fluid ejector modules through a thermally-conductive carriage molded from a polymer to the ambient air surrounding the structure upon which the thermally-conductive fluid ejector carriage translates. The heat is transferred via conduction and convection from the thermally-conductive fluid ejector carriage across a thin volume of air trapped between a thermally-conductive carriage rod guide, enclosed on each end by thermally-conductive carriage rod guide bearings, and the thermal contact of the thermally-conductive carriage rod guide bearings with the surface of at least one thermally-conductive carriage guide rod which the thermally-conductive fluid ejector carriage translates.

  • Patent number: 7163275
    Abstract: Methods and apparatus provide for automatic fluid ejector alignment and performance evaluation and modification in one or multiple planes. A fluid ejector fires a drop through a drop detection module. A signal indicating drop presence or absence is sent to a computer. The computer analyzes the data, and makes a compensation determination of a preferred method of using the fluid ejector. The compensation determination may include electronically modifying the image data to be printed, physically manipulating the fluid ejector, completely skipping the fluid ejector during printing operations, or in some other way modifying the fluid ejector or image data such that apparent printed image error due to fluid ejector alignment or performance error is reduced.

  • Patent number: 6721070
    Abstract: An independent hardware pixel counter counts bits of print data in regions of interest. The independent pixel counter can be an application specific integrated circuit (ASIC), and is separate from a control processor. The independent hardware pixel counter selectively monitors a data bus carrying image data to or from a memory. Once the pixels of the image data have been counted, the count data can be sent to the control processor in order to implement a print strategy. The pixel counter counts the print data at a point when image data is being sent to the memory, since at that point the image data is both uncompressed and in a raster format, and thus can be easily analyzed. Additionally, because the image data is stored in the memory until enough print data has accumulated for printing, the processor is provided with sufficient time to gather and use print information before the counted image data is printed.

  • Patent number: 6666535
    Abstract: A method and apparatus prevents satellite induced banding caused in bi-directional printing in which a print head alternatively moves in a first printing direction and in a second printing direction opposite to the first printing direction. The ink jet printer includes a controller that performs at least one of (i) selectively removing pixels in the first printing direction in order to lighten an image, and (ii) selectively adding pixels in the second printing direction in order to darken the image.
