摘要： An analyzer for electrophoretic samples has a sample stage movable linearly with respect to a source and a detector of analysis energy. During a first scan of the sample, a voltage is produced representing either the minimum detected fluorescence or the minimum detected optical density. During a second scan, the voltage is combined with the output of the detector to automatically correct the output to a reference.

摘要： A pulse discriminator circuit for use in a closed loop scanning and positioning system for finding and positioning white blood cells. The surface of a slide is scanned to produce an optical signal which is converted by a sensor into an electrical signal. This signal is applied to the pulse discriminator circuit which provides an output pulse only when a white blood cell is being scanned. The output of the pulse discriminator is coupled to a logic circuit which produces signals that are used to drive the microscope stage to cause the white blood cell to be positioned within a small aperture in the optical system.
