    Abstract: Methods and techniques of using 3D printers to create physical models from image data are discussed. Geometric representations of different physical models are described and complex data conversion processes that convert input image data into geometric representations compatible with third party 3D printers are disclosed. Printing templates are used to encapsulate complex geometric representations and complicated data conversion processes from users for fast and simple 3D physical model printing applications.

    Abstract: An integral blender includes a hollow shell having a horizontal conical plate integrally formed in the interior to divide the interior of the hollow shell into a container portion and a base portion. The conical plate has a through hole. The base portion is employed to accommodate a transmitting mechanism provided with a shaft extending out of the through hole to be fixedly connected with a cutter in the container. The shaft is closely wrapped with a waterproof annular seal having the bottom combined together with the conical plate. Therefore, with the container portion and the base portion integrally formed together, manufacturing cost can be lowered and convenience in practice can be advanced.

    Abstract: A re-configurable circuit acts as an Analog-to-Digital Converter (ADC) and as a digital-to-analog converter (DAC). An array of binary-weighted capacitors stores an analog input. Switches connect different capacitors in the array to fixed voltages that cause charge-sharing with a terminal capacitor. The voltage of the terminal capacitor is compared by a re-configurable comparator stage for each different combination of the capacitors. The comparison results are analyzed to determine the closest digital value for the analog input. In DAC mode, the array capacitors are switched based on an input digital value. The switched capacitors connect to a charge-sharing line to generate an analog voltage that is applied to the re-configurable comparator stage. A differential amplifier generates a buffered analog voltage that is fed back to the other input of the re-configurable comparator stage for unity gain. The gain of the re-configurable comparator stage adjusts for ADC and DAC modes.

    Abstract: An apparatus for star catalog equalization to enhance attitude determination includes a star tracker, a star catalog and a controller. The star tracker is used to sense the positions of stars and generate signals corresponding to the positions of the stars as seen in its field of view. The star catalog contains star location data that is stored using a primary and multiple secondary arrays sorted by both declination (DEC) and right ascension (RA), respectively. The star location data stored in the star catalog is predetermined by calculating a plurality of desired star locations, associating one of a plurality of stars with each of the plurality of desired star locations based upon a neighborhood association angle to generate an associated plurality of star locations: If an artificial star gap occurs during association, then the neighborhood association angle for reassociation is increased. The controller uses the star catalog to determine which stars to select to provide star measurement residuals for correcting gyroscope bias and spacecraft attitude.
