Abstract: Blood constituents such as red cells, white cells, and platelets are centrifuged into layers in a capillary tube and the true extent of one or more of the layers is measured photometrically. Each layer to be measured is optically scanned by a sequence of scanning operations with the actual extent of each layer traverse being recorded in a computer. After each layer has been completely circumferentially scanned and each traverse recorded, the computer determines the true average axial dimension for each layer and computes, through prior input, the actual constituent count for each constituent layer.

Abstract: A machine learning model that uses composite metrology data determines at least one parameter of a device under test using measured metrology data from the device. The composite metrology data is generated by merging measured metrology data from a reference device with synthetic metrology data calculated from a model of the reference device. The composite metrology data may be generated further based on a synthetic metrology data calculated from a model for a modified reference device. The modified reference device may be generated using variations of at least one parameter of the model to expand the parameter space of the training range.
