  • Patent number: 12038452
    Abstract: The present invention makes a directional control means for a specimen carrier unnecessary, reduces costs, and saves time. A high friction member 102 is provided on the bottom surface of a specimen carrier 100, thereby offsetting the center 14 of the frictional force 11 between the bottom surface and a conveyance surface, at a position separate from the rotational center of the bottom part of the specimen carrier 100. As a result, the friction between the conveyance surface and the bottom surface during conveyance of the specimen carrier 100 aligns the orientation of the specimen carrier 100 with respect to a conveyance direction 10, and makes it possible to make a carrier ID 101 and a specimen ID label 151 face towards a barcode reader.

  • Patent number: 12019086
    Abstract: An improved system and method for the selection and dispensing of reagents onto a target testing medium in an automated laboratory environment. The system utilizes multiple carousels rotatably-mounted upon a central turntable. The position of the central turntable, as well as the rotation of each carousel is controlled by a microprocessor-based control system. Multiple dispensers, each capable of storing and dispensing a particular reagent, are mounted about the circumference of each carousel. This configuration provides much higher reagent density than previously available. The testing medium is positioned at one or more loading stations. The control system directs the central turntable to a position from which a selected one of the carousels can be rotated so as to position a selected dispenser above the testing medium. The selected dispenser is then actuated to release a predetermined reagent onto the testing medium.
