  • Methods and systems for calibration of a positional orientation between a sample container and nozzle tip
    Patent number: 9517468
    Abstract: Disclosed are methods to aid in a calibration of a vertical orientation of a nozzle tip to a sample container in a processing or testing system. The method includes positioning the nozzle over a calibration target at a home height location (HM), moving the nozzle downward a distance (D) until contact with the calibration target is sensed, positioning the nozzle over the sample rack and moving the nozzle downward until contact with a registration location is sensed, imaging the sample rack and calibration target to determine a height (H) between the registration location and calibration target, and calculating a translation ratio (TR) between the height (H) measured in pixel space and the distance (D) measured in machine space. The translation ratio (TR) may be used to drive the nozzle tip to a predetermined depth. A robot calibration system is disclosed, as are other aspects.

  • Method for increasing capacity in an automatic clinical analyzer by using modular reagent delivery means
    Publication number: 20050014272
    Abstract: An automatic clinical analyzer in which the number of cuvette ports available for reaction vessels on a reaction carousel are 50% in a configuration using a single reagent storage areas; in a second configuration an additional reagent storage areas is employed and additional ones of the cuvette ports on reaction carousel are utilized, thereby significantly increasing throughput.
