  • Patent number: 11573243
    Abstract: Provided is a temperature control system applied to an apparatus for analyzing a sample using a pipette nozzle and a reaction container, including a pipette tip temperature controller that heats a pipette tip which is fitted on the pipette nozzle and aspirates or discharges liquid and a reaction container temperature controller that heats the reaction container. The pipette tip temperature controller heats, in a concentrated manner, at least a distal end portion of the pipette tip of the pipette nozzle located at a predetermined heating position with hot air emitted from a heat source and is configured such that a distal end is capable of arriving at the reaction container by lowering the pipette nozzle from the heating position.

  • Publication number: 20220005205
    Abstract: An imaging apparatus includes a subject detection unit that detects a subject using an image signal output by an image sensor and a motion vector detection unit that detects a motion vector of the subject from the image signal. A camera control unit performs a process of recognizing a movement pattern using the motion vector of the detected subject and determines a group movement scene if it is determined that a movement of a plurality of subjects is a linear movement and the number of subjects with the same movement pattern is equal to or greater than a predetermined number. The camera control unit sets the subject in the lead in the movement direction among the plurality of subjects performing the liner movement in the determined group movement scene to a tracking target as a main subject.
