Abstract: A puck for removably supporting a receptacle. The puck includes a plurality of fingers arranged about a vertical axis, where each finger has a contact surface configured to be in contact with a receptacle seated in the puck. One or more springs couple the plurality of fingers, thereby biasing the fingers toward the vertical axis. The puck further includes a supporting disc having (i) a disc sidewall projecting from a base to define a pocket for seating a receptacle, (ii) a plurality of first cavities formed in the base and extending in a direction of the vertical axis, and (iii) a puck passageway extending through opposed portions of the disc sidewall in a direction transverse to and offset from the vertical axis, where each of the fingers is rotatably coupled to the supporting disc at a corresponding first cavity of the plurality of first cavities.

Abstract: A receptacle delivery system that includes a rail extending between first and second locations of an instrument and a carriage configured to move on the rail between the first and second locations of the instrument. The carriage includes a bracket having opposed first and second sidewalls and a base extending between the first and second sidewalls, where the carriage is configured to support a receptacle. The carriage further includes a pair of opposed support pads, where the pair of support pads are configured to (a) move toward a receptacle supported by the carriage as the carriage moves from the first location toward the second location, and (b) move away from a receptacle supported by the carriage as the carriage moves from the second location toward the first location. The carriage also includes a pair of meshed cam gears rotatably coupled to the first sidewall, where each cam gear is coupled to a different one of the support pads.

Abstract: A method of reading machine-readable labels on sample receptacles. In the method, a sample rack is moved between a first position and a second position withing a housing, where the sample rack supports a plurality of sample receptacles, and each sample receptacle has a machine-readable label. An absolute position of the sample rack is measured as the sample rack moves between the first and second positions. An image of the machine-readable label associated with each sample receptacle is acquired as the sample rack moves between the first and second positions. Finally, the acquired image of each machine-readable label is decoded.

Abstract: A container gripping mechanism includes first and second linear rails disposed on opposed sides of a linear rail mount. A first linear rail guide coupled with the first rail is supported on a first gripper finger mount, and a second linear rail guide coupled with the second rail is supported on a second gripper finger mount. A first gripper finger is secured to the first gripper finger mount, and a second gripper finger is secured to the second gripper finger mount. A pinion gear driven by a drive motor engages racks attached to the first and second gripper finger mounts, such that rotation of the pinion in a first direction causes the first and second gripper fingers to move toward each other, and rotation of the pinion in a second direction causes the first and second gripper fingers to move away from each other.

In embodiment, the chuck guide includes a yoke with opposed arms and spindles located near distal ends of the arms that engage beveled shoulders of the container holder.

Abstract: Method and associated system for reading machine-readable labels on a plurality of sample receptacles held by a sample rack. In the method, a machine-readable label associated each of the plurality of sample receptacles is read with a first label reader when the rack is at a first location. The sample rack is then moved from the first location to a second location, where a rack identifier on the sample rack is sensed with a sensor separate from the first label reader. Finally, the rack identifier is associated with the machine-readable labels of the plurality of sample receptacles.

Abstract: A system for processing a plurality of sample containers, each containing sample with at least one open assay associated therewith, includes two or more analyzers, each configured to perform at least one functional assay in receptacle apparatuses including a process number of two or more receptacle vessels, a conveyance for transporting containers to the analyzers, a buffer queue associated with each analyzer for holding containers to be processed by the associated analyzer, and a scanner associated with each analyzer. Each scanner scans machine-readable identification information associated with each container transported by the conveyance past the scanner and the open assay(s) for that container are identified based on the scanned information. The sample container is diverted into the associated buffer queue only if at least one open assay for that container matches at least one functional assay of the associated analyzer.

Abstract: A gripper apparatus is configured to grasp a closed receptacle having a closure affixed to an open top end of a receptacle. Opposed jaw members capable of lateral movement between an open position, a first closed position, and a second closed position are configured to grasp the closed receptacle when the closed receptacle is situated between the jaw members at the first closed position and to release the closed receptacle at the open position. The gripper apparatus further includes a plurality of fingers configured to grasp a sidewall of the closure beneath a top surface of the closure when the closure is situated between the plurality of fingers and beneath a base of each of the jaw members as the jaw members move laterally toward each other from the open position to the second closed position.

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.
