Correction circuit of the account of blood platelets

摘要

Circuitry for the correction of error occasioned during the counting of platelets in a hematology system. A coincidence corrected platelet count is provided as an input to a rate counter which provides a plurality of output signals representative of different percentages of the input count. A read-only memory is employed to store data representing correction factors for different hematocrit values. Gating circuitry is enabled by output signals from the read-only memory representing a selected hematocrit correction factor, the enabled gate circuits providing pulses representative of selected percentages of the input count and which are combined to provide an output pulse train which is the corrected platelet count.
