A personal communication device for processing financial information via a payment terminal, the payment terminal being configured to output a wireless signal is configured to receive the wireless signal of a payment terminal; determine whether the received wireless signal has a strength above a first signal threshold. If the received signal strength is above the first signal strength threshold, it emits a wireless request signal to cause the payment terminal to establish a communication channel with the personal communication device, wherein the request signal causes the payment terminal to establish only one communication channel, wherein the communication channel is only between the said personal communication device and the payment terminal. When a financial transaction at said personal communication device is concluded, it emits a wireless release signal to close down the communication channel so that the payment terminal can establish another communication channel with another personal communication device.

A clinical documentation improvement (CDI) smart scoring method may include predicting, via per-condition diagnosis machine learning (ML) models and based on clinical evidence received by a system, a probability that a medical condition is under-documented and, via per-condition documentation ML models and based on documentation received by the system, a probability that a medical condition is over-documented. The under- and over-documentation scores are combined in view of special indicators and queryability factors, which can also be evaluated using ML query prediction models, to generate an initial CDI score. This CDI score can be further adjusted, if necessary or desired, to account for factors such as length of stay, payer, patient location, CDI review timing, etc. The final CDI score can be used to prioritize patient cases for review by CDI specialists to quickly and efficiently identify meaningful CDI opportunities.

Logistical operations (e.g., warehouses) may use a voice-enabled workflow to facilitate the work tasks of a staff (i.e., population) of workers. Typically, it is necessary for a worker to travel from location-to-location to complete assigned work tasks. As such, a worker's time spent travelling often correlates with the worker's overall work performance. Understanding the worker's travel performance is highly desirable, but computing a fair and accurate travel-performance metric is difficult. One reason for this is that the distance a worker travels is often unknown. The present invention embraces a system and method for accurately and fairly assessing a worker's travel performance by analyzing the worker's voice dialog.

Systems, methods, and other embodiments associated with generating a price schedule are described. In one embodiment, for each customer segment of a plurality of customer segments, a per-segment value of an approximate objective function for the customer segment is determined by an optimizer, and a ratio of the per-segment value to a sum of all per-segment values for the customer segments is computed. The inventory quantity is allocated amongst the customer segments according to the ratio for each customer segment to form an inventory quantity for each customer segment. For each customer segment, a promotion portion of the price schedule that maximizes the objective function by the optimizer is determined. A quantity of remaining inventory allocated to the plurality of customer segments at an end of the regular season is aggregated. A markdown portion of the price schedule for the item that maximizes the objective function is determined by the optimizer. The promotion portion and the markdown portion are combined to create the price schedule for the item.
