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： 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： 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 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： Determining a dimensional change in a surface of an object is described. At a first time, a first image of the surface is acquired at a first spatial window thereon having a first known position relative to a frame of reference. At a second time, a second image of the surface is acquired at a second spatial window thereon having a second known position relative to the frame of reference. The first image and the second image are processed according to an image displacement sensing algorithm to determine a relative translation of a first point on the surface between the first and second times. The relative translation of the first point, the first known position, and the second known position are used to determine the dimensional change in the surface between the first and second times.

摘要： A contact lithography alignment system and method use nanoscale displacement sensing and estimation (nDSE) to maintain an alignment and compensate for a disturbance of one or more objects during contact lithography. A method of maintaining an alignment includes establishing an initial alignment of one or more objects and employing nDSE-based feedback control of relative positions of more or more of the objects to maintain the alignment during contact lithography. A method of disturbance compensation includes acquiring a first image, acquiring a second image, estimating an alignment error using nDSE applied to the first and second image, and adjusting a relative position to reduce the alignment error. A contact lithography system includes an optical sensor, a feedback processor providing nDSE and a position controller that adjusts relative positions of one or more objects to reduce an alignment error determined using the nDSE.

摘要： Methods of performing lithography include calculating a displacement vector for a lithography tool using an image of a portion of the lithography tool and a portion of a substrate and an additional image of a portion of an additional lithography tool and a portion of the substrate. Methods of aligning objects include positioning a second object proximate a first object and acquiring a first image illustrating a feature on a surface of the second object and a feature on a surface of the first object. An additional object is positioned proximate the first object, and an additional image is acquired that illustrates a feature on a surface of the additional object and the feature on the surface of the first object. The additional image is compared with the first image. Imprint molds include at least one non-marking reference feature on an imprinting surface of a mode base.
