  • Patent number: 12561647
    Abstract: Systems and methods for autonomous device procurement are disclosed. A system can obtain point-of-sale (POS) terminal demand data and execute a machine-learning model to generate a forecasted inventory demand for POS terminal devices. The system can allocate the forecasted demand among devices based on ratios, simulate demand instances, calculate losses, and modify the allocated demand based on the losses. The system can generate a procurement plan based on the modified demand. The system may autonomously procure devices according to the plan. The forecasted demand may comprise a probabilistic distribution for multiple future time periods. The system may calculate a conditional value at risk (CVaR) based on the losses and generate the plan based on the CVaR.

  • Patent number: 12301727
    Abstract: The present disclosure relates to establishing secure communication between a dialysis machine and medical equipment. In an example, a dialysis machine includes a control unit configured to establish a short-range wireless connection with external medical equipment. The control unit establishes the short-range wireless connection by causing a user interface to display a prompt to enter a passkey associated with medical equipment, using the received passkey to pair with the medical equipment, and creating a new bonding table or writing to an empty bonding table using the passkey. The control unit is also configured to generate a shared key using the passkey and at least one predetermined criterion and use the shared key to authenticate with the medical equipment. When authentication with the medical equipment is successful, the control unit enables data communication using the short-range connection with the medical equipment.
