  • Printer, printer system, printer control method, and program therefor
    Patent number: 6945717
    Abstract: A controller (4) for controlling a printer engine (7) used to print data on a medium determines an identification number based on received data, and prints the identification number together with print data based on the received data on the medium. Simultaneously, the controller (4) stores therein the identification number and the print data in an HD (6). With the construction, the identification number printed on the medium is inputted in the next and later printing operations. The controller (4) searches the HD (6) to retrieve and print the print data. Therefore, a copy of a quality as high as that of the original document can be produced.

  • System with motion triggered processing
    Patent number: 6947609
    Abstract: A document image capture (scanning) system and control method are described for scanning and processing document images received live from a camera. A motion detector detects image motion between two image frames. When the image is stationary, image processing (such as OCR) is carried out automatically and made available to the operator. In one form, when movement is detected, the image processing results are discarded until the image is newly stationary, whereupon new image processing is carried out on the new image. In another form, the degree of movement is evaluated; if the movement is small, then at least some of the previous image processing results are re-used by re-mapping on to the new image.

  • Method and system for adjusting color mixing due to substrate characteristics
    Patent number: 6947175
    Abstract: A method for adjusting fractional amounts of primary colors to be combined to substantially match a user selected color and substrate characteristics in a device adapted to color printing on a substrate. The method corrects for both the color and the reflectivity of the substrate on which the user selected color is to be printed. The method adjusts the target mixed ink transmission spectrum to compensate for the substrate characteristics. The method also identifies cases in which the target mixed ink transmission spectrum may not be compensated due to the paper's color. The method may be used to control mixing of inks in a custom color module of a marking engine; or mixing of dry toner primaries in a dry xerographic engine; or mixing of printing inks in a stand-alone ink mixing station.

  • Method for measuring the response of a voltage controlled oscillator
    Patent number: 6947515
    Abstract: A method for calibrating a VCO within a phase locked loop circuit is disclosed. First, a DAC output voltage is set to its minimum, and a counter M is adjusted until a comparator is its threshold voltage. Next, the DAC is set to another voltage, and counter M is again adjusted to the comparator threshold. This process is repeated for as many steps as desired. When the phase locked loop circuit requests an instantaneous frequency, an interpolation of the requested frequency against the curve created by the above-described method gives the value required by the DAC.

  • Soft picture/graphics classification system and method
    Patent number: 6947597
    Abstract: A method and system for image processing, in conjunction with classification of images between natural pictures and synthetic graphics, using SGLD texture (e.g., variance, bias, skewness, and fitness), color discreteness (e.g., R_L, R_U, and R_V normalized histograms), or edge features (e.g., pixels per detected edge, horizontal edges, and vertical edges) is provided. In another embodiment, a picture/graphics classifier using combinations of SGLD texture, color discreteness, and edge features is provided. In still another embodiment, a “soft” image classifier using combinations of two (2) or more SGLD texture, color discreteness, and edge features is provided. The “soft” classifier uses image features to classify areas of an input image in picture, graphics, or fuzzy classes.

  • Simple mechanism for profile selection
    Patent number: 6947174
    Abstract: In a system where the color space conversion process uses color profile look-up tables to select a profile for each of the possible attribute value combinations, assigning a value of wildcard to one or more attributes. In this case, if all of the values of one of the attributes can not be exactly matched, and that attribute has a wildcard value, the wildcard value is selected. The profile associated with the wildcard is designed to enable a reasonable color conversion in any case where an attribute calls for a particular value and the printer does not have a corresponding profile. The result is that the printer will most likely still print a reasonable image in the case where there is no matching profile.

  • Sacrificial circuit connector for connect/disconnect applications that exceed the rated cycle limits of circuit connector terminals
    Patent number: 6945822
    Abstract: A sacrificial circuit connector for interposition between male and female connector terminals for applications in which the expected connect and disconnect cycles may exceed the rated cycle limits of at least one of the connector terminals. The structure of sacrificial connector is largely determined by the need for connection compatibility between the sacrificial connector and the connector terminals. By making repeated disconnections at the sacrificial connector rather than between the connector terminals, the usable life of at least one connector terminal can be significantly increased, thereby adding efficiency and reliability while decreasing costs.

  • Photolithographically-patterned out-of-plane coil structures and method of making
    Patent number: 6947291
    Abstract: An out-of-plane micro-structure which can be used for on-chip integration of high-Q inductors and transformers places the magnetic field direction parallel to the substrate plane without requiring high aspect ratio processing. The photolithographically patterned coil structure includes an elastic member having an intrinsic stress profile. The intrinsic stress profile biases a free portion away from the substrate forming a loop winding. An anchor portion remains fixed to the substrate. The free portion end becomes a second anchor portion which may be connected to the substrate via soldering or plating. A series of individual coil structures can be joined via their anchor portions to form inductors and transformers.

  • MEMS optical latching switch
    Patent number: 6947624
    Abstract: An optical micro-electro-mechanical system (MEMS) switch is disclosed. In a preferred embodiment the optical MEMS switch is used as an M×N optical signal switching system. The optical MEMS switch comprises a plurality of optical waveguides formed on a cantilever beam platform for switching optical states wherein the state of the optical switch is changed by a system of drive and latch actuators. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning the cantilever beam platform. In use the optical MEMS device may be integrated with other optical components to form planar light circuits (PLCs). When switches and PLCs are integrated together on a silicon chip, compact higher functionality devices, such as Reconfigurable Optical Add-Drop Multiplexers (ROADMs), may be fabricated.
