Abstract: A printing module configured to print a label on a curved surface of an article includes an expandable printing mechanism configured to be expanded to an open configuration for receiving the article or contracted to a closed configuration placing the curved surface in an operative position with respect to a print head and an article moving assembly configured to grasp and hold the article and effect relative movement between the curved surface and the print head. The printing mechanism includes contact elements, such as rollers, that contact or otherwise engage the article when the printing mechanism is in the closed configuration and maintain the curved surface in the operative position with respect to the print head during relative movement between the curved surface and the print head.

Abstract: A diagnostic system performs a first nucleic acid amplification reaction and a second, different nucleic acid amplification reaction. The diagnostic system includes a compartment configured to store at least a first bulk reagent container comprising a first bulk reagent for performing a sample preparation process, and a second bulk reagent container comprising a second bulk reagent for performing the first reaction. The system including a compartment configured to store at least one unit-dose pack comprising a plurality of unit-dose reagents for performing the second reaction. The diagnostic system is configured to perform the sample preparation process using the first bulk reagent on each of a plurality of samples provided to the diagnostic system. The system is configured to perform the first reaction using the second bulk reagent on a first sample subset, and perform the second reaction using the plurality of first unit-dose reagents on a second sample subset.

Abstract: A processing module is configured to extend the capabilities of an analyzer configured to process substances within each of a plurality of receptacles. The module includes a container transport configured to transport a container from a location within the processing module to a location within the analyzer that is accessible to a substance transfer device of the analyzer. A receptacle distribution system is configured to receive a receptacle from the analyzer, transfer the receptacle into the processing module, and to move the receptacle between different locations within the analyzer. A substance transfer device of the module is configured to dispense substances into or remove substances from the receptacle within the processing module. A reagent card exchanger provides an input device for inserting reagent cards into and removing reagent cards from the module, stores reagent cards within the module, and transfers reagent cards to different location within the module.

Abstract: A method is disclosed for reliably calibrating a sensor used in diagnostic sensing of a predetermined parameter, e.g., CO.sub.2 partial pressure, O.sub.2 partial pressure, or pH, of a solution such as blood, the method compensating for expected variations over time in the value of the parameter in a calibration solution. The parameter of the calibration solution has a predetermined initial value, and the solution is initially located within a container that is configured to allow the value of that parameter to vary over time in a predetermined manner. Supplying the calibration solution to the sensor causes the sensor to produce a calibration solution signal, which is compared with a calculated value for the parameter based on its expected variation over time, to produce a calibration factor. Thereafter supplying the test fluid to the sensor causes the sensor produces a test fluid signal, and this test fluid signal then is adjusted in accordance with the calibration factor.

Abstract: An improved apparatus is disclosed for maintaining a medical assembly, e.g., a blood chemistry electrode assembly, filled with a bubble-free storage liquid for an extended storage time period. The apparatus achieves this result by connecting to the assembly a pressurized reservoir that supplies additional storage liquid, to replenish any storage liquid lost due to diffusion from the medical assembly.
