Publication number: 20240401379Abstract: Described herein is a lock system (e.g., for a vehicle door) including an NFC circuit in communication with a microcontroller that monitors the voltage of a battery (e.g., the vehicle battery). The microcontroller switches the NFC circuit to card emulation (CE) mode with energy harvesting capability when the battery voltage falls below a threshold so that the NFC circuit can harvest energy from a nearby Qi wireless charging field and store that harvested energy in an energy storage device. When the energy storage device is sufficiently charged, it is used power the microcontroller and an electronically actuated mechanical lock (e.g., vehicle door lock), then the microcontroller cooperates with the NFC circuit to switch the NFC circuit to NFC reader mode and attempt to verify a nearby NFC device. If the NFC device is verified, the microcontroller operates the lock, otherwise, it maintains the lock in an inactive state.Type: ApplicationFiled: May 30, 2023Publication date: December 5, 2024Applicant: STMicroelectronics International N.V.Inventor: Rene WUTTE
