Patent number: 11960311Abstract: A linear voltage regulator with isolated supply current is disclosed. The voltage regulator is configured and controlled such that its output current closely matches its input current (any quiescent current consumed by the regulator is negligible relative to the amount of current passed by the regulator). In certain implementations, the voltage regulator is implemented as an analog component. In other implementations, the voltage regulator includes or cooperates with digital elements, such as an analog-to-digital converter, a digital processing core, or a digital-to-analog converter.Type: GrantFiled: July 28, 2020Date of Patent: April 16, 2024Assignee: Medtronic MiniMed, Inc.Inventors: Seth N. Kazarians, Adam S. Trock, Jalal Elidrissi, Fatemeh Delijani

Publication number: 20230344255Abstract: Embodiments are provided for dynamic management of charge. The techniques may involve obtaining an estimated readiness time for an energy storage element, obtaining a target state of charge for the energy storage element, calculating an estimated charging time based at least in part on a difference between the target state of charge and a current state of charge, using a first charging rate to charge the energy storage element to an intermediate state of charge, and responsive to determining the amount of time remaining before reaching a second estimated readiness time is less than an updated estimated charging time to charge the energy storage element at the intermediate state of charge to the target state of charge, using a second charging rate to charge the energy storage element to the target state of charge, wherein the second charging rate is greater than the first charging rate.Type: ApplicationFiled: June 26, 2023Publication date: October 26, 2023Inventors: Jalal Elidrissi, Adam S.

Patent number: 11650248Abstract: A test system for measuring electrical current consumption of a device under test (DUT) includes a capacitor with power and ground terminals; a voltage regulator with input and output terminals; first and second switching elements; and a controller. The voltage regulator generates a DUT operating voltage based on its input voltage. The first switching element is arranged between a direct current (DC) voltage source and the regulator input, and the second switching element is arranged between the DC voltage source and the capacitor. The controller operates the switching elements to charge the capacitor, and to configure the test system for measuring operating current of the DUT using the capacitor as the power source.Type: GrantFiled: July 28, 2020Date of Patent: May 16, 2023Assignee: Medtronic MiniMed, Inc.Inventors: Seth N. Kazarians, Adam S. Trock, Jalal Elidrissi, Fatemeh Delijani
