摘要： A printer having a transparency film discrimination system is disclosed. The printer includes a feed mechanism, an illumination source, a detector, and a processor. Light from the illumination source is reflected on or transmitting through the print medium (such as a transparent film) and is detected by the detector. The detected light is analyzed to determine the type of the medium. If the determined type of the print medium is not acceptable for the printer, then control signal is provided to the printer to halt the printing process as to avoid damage to the printer.

摘要： A printer is provided with a transmit electrode and a receive electrode with a dry-toner cartridge located therebetween. The transmit and receive electrodes act as two plates of a capacitor, with the toner within the toner cartridge making up a portion of the dielectric between the two capacitor plates. An oscillating transmit signal is then applied to the transmit electrode, and a signal corresponding to the capacitance between the opposing electrodes is detected. The changing capacitance due to the changing toner quantity causes a change in the received signal. The value of the received signal is then converted into the quantity of toner residing between the opposing electrodes, and this quantity is displayed to the user. Arrangements of transmit and receive electrodes may be employed within the printer to not only sense the overall quantity of toner but the distribution of toner within the toner cartridge.

摘要： A probabilistic input-output system is used to classify media in printer applications. The probabilistic input-output system uses at least two input parameters to generate an output that has a joint dependency on the input parameters. The input parameters are associated with image-related measurements acquired from imaging textural features that are characteristic of the different classes (types and/or groups) of possible media. The output is a best match in a correlation between stored reference information and information that is specific to an unknown medium of interest. Cluster-weighted modeling techniques are used for generating highly accurate classification results. Within the imaging process, grazing angle illumination (i.e., introducing light at an angle of at least 45 degrees to the normal of the surface being imaged) provides sufficient contrasts for distinguishing the structural features (e.g., paper fibers) of the unknown medium, but non-grazing illumination may be used when specular measurements are to be obtained.

摘要： The present invention is a method and device for identifying recording media in a printer. The invention utilizes fine structure of the media revealed by illumination from one or more directions to distinguish among different kinds of plain papers, coated papers, such as glossy papers, and transparency films. Multiple light sources at different incidence and/or orientation angles apply light on the test surface, and scattered light is converted into signals and then analyzed. Various metric and analysis techniques can be applied to the signals to determine the media type.

摘要： A print monitoring approach is provided in which sequences of irregular two-dimensional frames of image information are captured at a resolution sufficiently high to enable details of individual droplets to be identified. The approach may be used to monitor individual droplets deposited on a medium, such as a sheet of paper, by an inkjet printhead. An optical detector having an irregular two-dimensional array of closely spaced sensor elements is mounted for movement with the inkjet printhead or other print assembly. A processor is responsive to the image frames from the optical detector to adjust print quality parameters when the physical characteristics of the imaged droplets are detected as being outside of a preselected range of acceptability. The physical characteristics that are resolved may include gyrational information or different droplet position information. Optical dot gain can also be measured.

摘要： The present invention provides a novel one-step process for preparing an aqueous polymer dispersion by the free radical aqueous emulsion polymerization comprising mixing at least water, a dispersant, and an oil-soluble initiator; raising a temperature from the starting to the end reaction temperature while metering at least ethylenically unsaturated monomers and a water-soluble initiator into a reaction vessel, conducting polymerization of the monomers in the presence of the water-soluble initiator at a temperature up to the end reaction temperature, and when the temperature has reached the end reaction temperature, conducting polymerization by the oil-soluble initiator. The oil-soluble initiator is inactive at the starting reaction temperature and becomes more active as a temperature approaches the end reaction temperature at which the oil-soluble initiator is fully active.

摘要： A measurement process or system transforms image data corresponding to images of an object to the frequency domain and analyzes the frequency domain data to determine a displacement of the object occurring between first and second images. Analysis in the frequency domain simplifies identification and handling of data expected to be noisy. In particular, frequencies corresponding to modes of vibration, lighting variation, or sensor error characteristic of a measurement system or frequencies corresponding to small magnitude frequency-domain data can be given little or no weighting in analysis that provides the displacement measurement. In one embodiment, Fourier transforms of shifted and unshifted images differ by a phase delay. A least square fit slope of the phase values associated with the phase delay can indicate displacements to accuracies less than 1% of a pixel width, thereby providing nanometer scale precision using imaging systems having a pixel width of about 1 μm.
