摘要:
A computer-based apparatus, including: a memory element storing computer readable instructions; a processor; and a source element to expel a first plurality of drops of a substance with a known density through a medium, and under a set of conditions. The processor executes the computer readable instructions to calculate uncalibrated volumes for the first plurality of drops using respective images of drops in the first plurality of drops. The source element expels a second plurality of drops of the first substance through the medium, and under the first conditions. The processor executes the computer readable instructions to: calculate, using a weight for the second plurality of drops and the known density, actual volumes for the second plurality of drops; and generate, using uncalibrated volumes and the actual volumes, an equation to modify the uncalibrated volumes to match the actual volumes.

An ink jet printhead maintenance system, which can be part of an ink jet printer, for removing ink residue from a printhead faceplate. The printhead maintenance system can include a supply of liquid which can be applied to the ink residue on the printhead faceplate using various techniques, such as those described. The liquid can include a monomer and/or an oligomer. The wet clean system described can be more effective in removing ink residue which can result from certain inks, such as ultraviolet curable gel inks, than previous printhead maintenance techniques.

摘要:
An indirect media flatness measurement system, and method, by which the appropriate level of hold-down force may be determined with some degree of quantitative accuracy. In an ink jet printer that is operative to subject a substrate media to a hold down force during printing, the method including printing a predetermined test image having a predetermined pattern on a substrate media using an ink jet print apparatus to produce a test print. Optionally, pattern may be an array of test symbols. The test symbol may include a line printed on the substrate media in a direction perpendicular to a process direction of the printer. The test print is compared with the predetermined test image, including measuring drop placement errors of test symbols. The height of the substrate media at the location of each test symbol is calculated based upon the drop placement error.

Embodiments of the invention relate to organizing data records in a relational database. An aspect of the invention includes creating index items for a plurality of data records. Each index item includes a counter and the creating results in a plurality of counters. The numerical values of counters in corresponding index items are updated for data records in the plurality of data records that are subjected to random access. The plurality of data records are reorganized based upon the numerical values of the plurality of counters.
摘要:
A method and apparatus to meter ink for electrographic printing is disclosed. An ink loading mechanism having an anilox roller fills ink from an ink supply into cells in the anilox roller having a plurality of valleys and lands that form the cells. The ink loading mechanism causes the valleys to be full or nearly full with the ink. The anilox roller rotates in a first direction. In one embodiment, a soft blade positioned slightly below surface of the lands removes ink from the cells and causes the valleys to be partially filled as the anilox roller rotates. A hard blade positioned at the surface of the lands to clean residue of ink on the surface of the lands as the anilox roller rotates. In another embodiment, a blanket roller rotationally engaged with the anilox roller pulls ink out of the cells and causes the valleys to be partially filled. The blanket roller rotates in a second direction. A first cleaning blade cleans tops of the lands of the cells.
摘要:
A linear surgical stapler includes an upper staple cartridge receiving half-section, a lower staple cartridge receiving half-section and a staple cartridge assembly. The staple cartridge assembly includes a cutting groove in which a reciprocating movement cutter is mounted. The cutter includes a bottom surface and a knife blade located at a far end of the cutter. The staple cartridge assembly includes a restricting member mounted therein and an elastic stopper. The elastic stopper abuts against the restricting member when the staple cartridge assembly is in an initial state. The restricting member breaks away from the staple cartridge assembly when the staple cartridge assembly is in a firing complete state, thereby preventing the cutter from sliding towards the far end of the staple cartridge. As a result, misfiring throughout the whole operation of the linear surgical stapler is prevented.
