A control device for wireless tags which are respectively attached to a plurality of articles supported respectively on a plurality of support portions and respectively store identification numbers of the articles, includes positioning portions that are respectively provided corresponding to the plurality of support portions, and input devices that are positioned respectively in the positioning portions. The input devices are individually controllable and each is configured to switch a flag status of one of the wireless tags.

In a sample-analyzing system including an analyzer (10) for analyzing a sample, an auto-sampler (20) for sequentially introducing a plurality of samples into the analyzer (10), and a controller (40) for controlling operations of the analyzer (10) and the auto-sampler (20), the auto-sampler (20) is provided with a sample rack holder (24) for holding a sample rack (21) having a plurality of wells (22) in which sample containers (23) are to be set and a sample rack imager (27) for taking, directly from above or obliquely from above, an image of the sample rack (21) held in the sample rack holder (24), whereby an incorrect input of the position information of the sample container (e.g. the well number or rack number) into an analysis schedule table is prevented.

A rack for holding samples and various reagents, wherein the rack may be used for loading the samples and reagents prior to using the reagents. The rack accepts complementary reagent holders, each of which contain a set of reagents for carrying out a predetermined processing operation, such as preparing biological samples for amplifying and detecting polynucleotides extracted from the samples.

A method for determining the presence or absence of disposable pipette tips in pipette tip carriers on the work area of a laboratory workstation. Each of the pipette tip carriers has a support panel with receiving holes into each of which a disposable pipette tip can be inserted. The laboratory workstation for carrying out the method has a robot arm with at least one pipette which is designed to receive and dispose of disposable pipette tips. The laboratory workstation has a digital camera which is arranged on a support device and is operatively connected to an analyzing unit. The work area of the laboratory workstation can be completely imaged in at least one first direction using the digital camera.

This disclosure is directed to a system and method for detecting a surface of a substrate within a scanner.

Provided are methods for the automated loading and/or automatic processing of one or more samples in an automated sample processing device. Also provided are automated sample loading systems and devices that include automated sample loading systems or devices that are utilized in such systems.

A model-based method of classifying a specimen in a specimen container. The method includes capturing images of the specimen and container at multiple different exposures times, at multiple different spectra having different nominal wavelengths, and at different viewpoints by using multiple cameras. From the captured images, 2D data sets are generated. The 2D data sets are based upon selection of optimally-exposed pixels from the multiple different exposure images to generate optimally-exposed image data for each spectra. Based upon these 2D data sets, various components are classified using a multi-class classifier, such as serum or plasma portion, settled blood portion, gel separator (if present), tube, air, or label. From the classification data and 2D data sets, a 3D model can be generated. Specimen testing apparatus and quality check modules adapted to carry out the method are described, as are other aspects.

A model-based method of determining characteristics of a specimen container. The method includes providing a specimen container, capturing images of the specimen container at different exposures times and at different spectra having different nominal wavelengths, selecting optimally-exposed pixels from the images at different exposure times at each spectra to generate optimally-exposed image data for each spectra, and classifying the optimally-exposed pixels as at least being one of tube, label or cap, and identifying a width, height, or width and height of the specimen container based upon the optimally-exposed image data for each spectra. Quality check modules and specimen testing apparatus adapted to carry out the method are described, as are other aspects.

A method for determining a position of a rack on a rack placement unit of a laboratory handling system is presented. The rack is configured to carry a number of laboratory sample containers. The method comprises measuring a height profile of the rack, determining at least one corner region of the rack based on the measured height profile of the rack, and determining the position of the rack based on the determined at least one corner region of the rack.

Systems for reading machine-readable labels, for example, two-dimensional barcodes, include a housing, a reader configured to read the machine-readable labels on sample receptacles as a sample rack holding the sample receptacles move between a first position and a second position within the housing. The system includes a processing and control unit configured to decode a read image of the machine-readable labels on each sample receptacle, and configured to associate a decoded read images with the corresponding sample receptacles based on measured positions of the sample rack when the machine-readable label was read.
