  • Patent number: 11965817
    Abstract: Disclosed is a cell classification method, to be executed by an analyzer, for classifying cells contained in a specimen, including: preparing a first measurement sample by treating a specimen under a first preparation condition; obtaining a first signal from the prepared first measurement sample; classifying, by using the first signal, cells contained in the first measurement sample; preparing a second measurement sample by treating the specimen under a second preparation condition different from the first preparation condition; obtaining a second signal from the prepared second measurement sample; classifying, by using the second signal, cells contained in the second measurement sample; and comparing a result of the cell classification performed by using the first signal and a result of the cell classification performed by using the second signal, with each other, and outputting an analysis result including a number of cells on the basis of a result of the comparison.

  • Publication number: 20240109474
    Abstract: A light distribution control device, if a first upper limit number N1?the number of near-distance targets T1, controls a lamp to irradiate the near-distance targets with light having illuminance according to attributes of the near-distance targets; if a remaining number M?the number of long-distance targets T2, controls the lamp to irradiate the long-distance targets with light having illuminance according to attributes of the long-distance targets; if N1<T1, controls the lamp to form a light distribution pattern that does not depend on the near-distance targets and the long-distance targets; and, if M<T2, controls the lamp to form a light distribution pattern that does not depend on the long-distance targets.

  • Publication number: 20220097658
    Abstract: A vehicle cleaner system according to the present invention includes: cleaner units that eject cleaning fluid to on-vehicle objects to be cleaned; motor pumps that supply the cleaning fluid to the cleaner units; normally closed solenoid valves provided between the cleaner units and the motor pumps to switch between allowance and disallowance of the transfer of the cleaning fluid from the motor pumps to the cleaner units; and a cleaner control unit that controls the motor pumps and the solenoid valves. The cleaner control unit sets an operation stop time t2, for which at least one of a motor pump and a solenoid valve is stopped, and stops, on the basis of a predetermined condition, the operation of the at least one of the motor pump and the solenoid valve for the duration of the operation stop time t2 after the cleaning fluid is ejected to the object to be cleaned.
