Abstract: A build material conveyor is disclosed. Such conveyor comprising an auger to transport build material in a substantially vertical direction wherein the conveyor further comprises a set of wall elements selectively positioned to, in a first position occupy part of the volume of the auger.

Abstract: A method for operating a plurality of stations in a cooperative station network, wherein each of the stations transmits signals and receives signals from other stations, includes determining a path loss between at least two of the stations. A carrier sense range for signals of a first station of the stations is determined based on the path loss and received power of signals from the other stations. A load on a dedicated signal exchange channel is determined based on the determined carrier sense range. A maximum output power for the first station is determined based on the determined load. The first station is operated by adjusting the output power of the first station to be, at least on average below the determined maximum output power for the first station.

Abstract: The present invention relates to a method for obtaining connective mesenchymal stem cells from the mononuclear fraction of human bone marrow cells using type AB human serum as a supplement. Said method includes the steps of obtaining said mononuclear fraction of bone marrow, the step of recovering and pre-expanding the connective stem cells and the step of expanding the connective stem cells until obtaining the clinical dose required for the therapeutic use thereof.

Abstract: Procedure for the undifferentiated or myeloid lineage biased expansion of haematopoietic stem cells coming from umbilical cord blood, mobilized peripheral blood or bone marrow. Procedure for the undifferentiated or myeloid lineage biased expansion of haematopoietic stem cells (HSCs). More specifically, the present invention relates to a procedure of expansion of HSCs from umbilical cord blood, bone marrow or mobilized peripheral blood. Said procedure comprises the steps of expansion culturing of the purified CD34+ cells at constant volume, expansion culturing of said cells at variable volume and the conditioning of the CD34+ cells for transplantation. With this procedure the dose of undifferentiated or myeloid lineage biased HSCs which is necessary for their clinical use is produced reproducibly, robustly and safely.

Abstract: A method for preparing a mask for multi-pass printing, comprises determining a characteristic satellite drop spray pattern for printing in a multi-pass mode with a printhead. Positions in the mask are filled with pass numbers. The pass numbers in a given position are selected based on considerations of interactions among main drops and satellite drops.

Abstract: A technique for assessing nozzle health of a printhead nozzle array in a printing system includes printing a swath portion of an image, optically scanning the printed swath portion to capture a scanned image, comparing an expected image of the swath portion of the image with the scanned image, and assessing whether any nozzles of the nozzle array have malfunctioned. A sensor can be mounted on a printhead carriage to accomplish the image capture.

Abstract: An incremental printer adapted to print an image in a series of swaths, comprising a sensor adapted to determine the height of a printed swath of the image by scanning the swath as it is printed, the printer being controlled to take into account the determined height when printing a subsequent swath of the same image.
