Abstract: A system derives training set factors for a customer sentiment score associated with a training set customer corresponding to training set support tickets, and a training set factor for a rate of a critical status corresponding to the training set support tickets. The system uses the training set factors to train a machine-learning model to determine a customer health score associated with the training set customer. The system derives factors for a customer sentiment score associated with a customer corresponding to support tickets, and a factor for a rate of a critical status corresponding to the support tickets. The trained machine-learning model uses the factors to determine a customer health score associated with the customer. The system enables a selection of escalating any customer account, de-escalating any customer account, escalating any support ticket, and/or de-escalating any support ticket, associated with the customer, in response to outputting the customer health score.

Abstract: An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface configured to engage with the step feature and resist further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. This interlocking engagement may allow the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by pulling the dilator in the opposite direction. The present technology also provides a dilator hub with a spring mechanism configured to achieve and maintain a desired tension on the expandable sheath and to prevent overextension of the expandable sheath when the dilator is being inserted into the expandable sheath.

Abstract: Systems and methods for auditing business controls are disclosed. The system may receive or retrieve data from one or more data sources corresponding to a business control. The system may perform a direct analytic control test (ACT) or an indirect ACT on the data. The system may compare a direct ACT result or an indirect ACT result to an ACT threshold. The ACT threshold may comprise separate direct ACT thresholds and indirect ACT thresholds. Based on the comparison, the system may determine an operating effectiveness of the business control.
