Abstract: Systems and methods are disclosed for receiving a digital image corresponding to a target specimen associated with a pathology category, determining a quality control (QC) machine learning model to predict a quality designation based on one or more artifacts, providing the digital image as an input to the QC machine learning model, receiving the quality designation for the digital image as an output from the machine learning model, and outputting the quality designation of the digital image. A quality assurance (QA) machine learning model may predict a disease designation based on one or more biomarkers. The digital image may be provided to the QA model which may output a disease designation. An external designation may be compared to the disease designation and a comparison result may be output.

Abstract: An improved apparatus and method is disclosed for determining a torque imposed on the rotatable shaft based on its torsional displacement, said apparatus comprising a rotatable shaft with at least four paired probes positioned at each end of the shaft to detect and compensate for motion induced errors. Paired first and second horizontal probes are positioned 180 degrees apart and paired first and second vertical probes are also positioned 180 degrees apart, in parallel planes perpendicular to the long axis of the shaft. In addition, the paired first and second horizontal probes, are positioned 90 degrees apart from the paired first and second vertical probes. If the shaft moves horizontally, the time of arrival detected by the first horizontal first and second probes will be later than a nominal value and the time of arrival for the second horizontal first and second probes will be earlier than a nominal value with the same amount of error.
