Patent number: 12633829Abstract: A hybrid active controller for practically asymptotically stabilizing the DC-DC boost converter under parameter uncertainty. The controller uses an estimation algorithm that identifies the input voltage and output load of the converter in finite time. Using these estimates, the control algorithm “unites” global and local control schemes. The global control scheme induces practical asymptotic stability of a desired output voltage and corresponding current, and the local control scheme maintains industry-standard PWM behavior during steady state. Stability properties for the resulting hybrid closed-loop system are established and simulation results illustrating the main results are provided.Type: GrantFiled: June 22, 2023Date of Patent: May 19, 2026Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Ryan S. Johnson, Berk Altin, Ricardo G. Sanfelice

Publication number: 20250097355Abstract: A system and method for assisted onboarding of multifunction peripherals to a cloud device management system uses a smartphone or tablet to commence a new device registration. A user determines whether to register using device information obtained directly via near field communication (NFC), if available, or via decoding a QR code output by the MFP. When NFC is used, the smartphone links to the MFP and downloads the device information. When QR codes are used, the smartphone scans the code and decodes it to get the device information. Device handshaking between the MFP and the cloud service is commenced by sending an instruction from the smartphone to the MFP for NFC registration, and by showing user instructions for commencing handshaking on the smartphone display when QR code registration is used.Type: ApplicationFiled: September 15, 2023Publication date: March 20, 2025Inventor: Ryan S.
