  • Patent number: 11031749
    Abstract: The description relates to laser control. One example can include a laser that has a laser emitter configured to generate a laser beam for intervals of time (e.g., pixel times). The laser can have a compensation and control component configured to receive a predicted laser emitter temperature of the laser emitter, obtain a desired optical power for an interval, and compute a compensated electrical current for the interval utilizing multiple light to current look up tables. Individual light to current look up tables can relate to specific laser emitter temperatures.

  • Patent number: 8845069
    Abstract: A circuit includes a capacitive-type humidity sensor. The circuit provides start and stop signals to a processor in accordance with a charge voltage across the sensor. The processor performs a counting function to derive an integer count value in response to the start and stop signals. The processor uses the integer count value to determine parameters for controlling an ink-jetting print engine. Printing speed can be controlled in accordance with ambient humidity and/or temperature so that the printed media are sufficiently dried before handling by a user or other operations.

  • Patent number: 7537304
    Abstract: Apparatus and methods for color calibrating low cost sensors in a printing system are disclosed. Exemplary embodiments include printing targets from multiple printhead die; making multiple readings of each target; fitting a curve to the acquired data; and generating calibration coefficients based on the fitted curve. Exemplary embodiments may include a generic calibration to map sensor measurements to a colorimetric color space, and a specific calibration to account for sensor-to-sensor variation.

  • Patent number: 7286261
    Abstract: Correcting color values for color calibration is disclosed. A sensor measures a color calibration pattern output by a device, to color values for the patch. Corrective action(s) are then performed on the color values. A first such action corrects for measurement corruption of a patch color of the patch resulting from the sensor erroneously measuring adjacent patch colors to the desired patch color. A second action corrects for non-parallel motion of the sensor while measuring the patch. A third corrective action corrects for ambient light detected by the sensor while measuring the patch, without necessarily filtering the sensor. A final action corrects for slow-drift measurement corruption of the patch, by both scaling and offsetting the color values.

  • Patent number: 6905187
    Abstract: A compact optical sensing system is used in hardcopy devices for scanning and/or printing images, for instance, using inkjet printing technology in desktop printing or in photographic printers appearing in grocery and variety stores. Several light emitting diodes (“LEDs”) illuminate a sheet of print media, and one or more photodiodes receive light reflected from the sheet. The photodiode generates signals in response to the light received, and the hardcopy device uses these signals to adjust printing parameters for optimal print quality. Using a chip-on-board process, the bare silicon die for each component is wire bonded directly to a printed circuit board assembly, allowing at least four LEDs (blue, green, red and soft-orange) to be grouped closely together in a space smaller than that occupied by a factory-made, single-packaged LED. A calibrating system uses a white target covered for cleanliness by a windowed door which is opened/closed by a printhead carriage.
