Abstract: A method for replacing a first sample carried on a moving secondary conveyor onto a moving primary conveyor at a potential interference point while the primary conveyor is transporting a second sample.

Abstract: A scheduling process for loading samples into two or more centrifuges in a loading scheme that reduces the time required for high priority sample to be centrifuged. One centrifuge is initially loaded to about one-half of capacity and samples processed while the remaining centrifuge is loaded to full capacity before being operated. This creates a time-shift in the operational status of the two centrifuges so that a high-priority sample may advantageously be shuttled to whichever of the two centrifuges will be first-fully loaded and thus next-operated.

Abstract: A method and a device for removing high priority samples from a primary conveyor and transferring such samples directly to an analyzer's sampling location even if other samples have been previously removed from the conveyor and are in a queue to be analyzed.

Abstract: A method for automatically operating a sample handling system and associated analyzers to conduct assays on a number of patient samples by comparing the assays to be conducted with a set of assay defined rules, subdividing the analyzers into analyzers which are in compliance with the assay defined rules and analyzers not in compliance with the set of assay defined rules; thereafter, operating the system to supply patient samples to analyzers in compliance or operating the system so as to bring at least one analyzer into compliance with the assay defined rules and supplying patient samples to such an analyzer.

Abstract: A computer interface module having a first information display screen that is directly linked to a plurality of additional information display screens containing on-line information about the operational status of plurality of interrelated automated devices as well as information describing the location of any specific sample and the status of clinical tests to be performed on the sample. A combination of general function buttons and specific function buttons as well as a scrollable text area where informational messages are displayed.

Abstract: A liquid aspiration method which includes a method for determining the quality of the aspirated sample through mathematical analysis of the pressure profile generated before, during, and after the aspiration process and comparison of the results with predetermined known values.

Abstract: Extracting a quantity of liquid from a closed container by driving a cannula having a passage the length of the cannula and a groove a partial length of the cannula through the closure of the container until the groove establishes communication between a pressurized chamber and the container, thereby forcing liquid from the tube through the passage.
