Title:
METHOD AND DEVICE FOR MEASURING TEMPERATURE OF VIBRATOR IN NON-CONTACT MANNER
Document Type and Number:
WIPO Patent Application WO/2024/090902
Kind Code:
A1
Abstract:
A method of determining a temperature of a vibrator included in a cartridge, includes: when the vibrator of the cartridge is coupled to a driving circuit of the electronic device, supplying a signal to the driving circuit; determining a phase difference between a current and a voltage between both ends of the vibrator and a shunt resistor; determining a reactance component of the vibrator based on a resistance value of the shunt resistor and the phase difference; and determining a temperature of the vibrator based on the reactance component.
