  • Patent number: 11893563
    Abstract: A reading system includes an evaluation value acquirer and a determining processor. The evaluation value acquirer is configured to acquire, with regard to a reading device configured to perform wireless communication with an electronic tag attached to each of one or more items by using a radio wave as a medium to read item information on each of one or more items, an evaluation value about at least one of: the number of times; a time interval; or a frequency, of reading the item information for each of at the one or more items. The determining processor is configured to determine, for each of the one or more items, whether or not each of the one or more items is an object to be read based on a change in the evaluation value over time.

  • Publication number: 20230236214
    Abstract: A dispensing device that dispenses a liquid sample with a target weight x (in grams) includes: a pipette that discharges the liquid sample into a vessel; and a controller that controls the pipette. The controller performs: first liquid discharge processing in which the controller discharges the liquid sample with a volume of (x/?0×y) milliliters (mL) into the pipette, where y is a numeric value greater than 0 and smaller than 1, and ?0 is the tentative density (in grams per mL) of the liquid sample; first weight acquisition processing in which the controller acquires information about the weight z (in grams) of the liquid sample discharged in first liquid discharge processing; density calculation processing in which the controller calculates the density p (in grams/mL) of the liquid sample according to the expression ?=z/(x/?0×y); and second liquid discharge processing in which the controller discharges, into the pipette, the liquid sample with a volume based on the density ?, weight z, and target weight x.
