    Abstract: Automated systems and methods determine a level of fluid relative to a rim of a sample receptacle defining an open top of the sample receptacle. The systems and methods utilize a distance sensor to measure the distance between the rim of the sample receptacle and the surface of a fluid sample contained in the sample receptacle, where at least one of the sensor and the sample receptacle is moved relative to the other to enable the sensor to obtain a sequence of discrete measurements of distances between the sensor and the rim of the sample receptacle and between the sensor and the surface of the fluid sample. A controller processes an output signal from the sensor to determine a level of the fluid relative to the rim of the sample receptacle. The derivative of the sequence of discrete measurements may be used to identify the rim and the fluid surface in the output signal.

    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.
