US Patent 12070079 Inhalation device controller

An inhalation device controller includes a power supply unit configured to supply power to an atomizer including a heater configured to heat an aerosol source, a detection circuit configured to detect a resistance value of the heater, a processor configured to generate a control signal in accordance with a smoothed signal generated by smoothing information obtained using the detection circuit, and a holding portion configured to hold the atomizer in a detachable state. The holding portion includes a first electrical contact contacting a third electrical contact of the atomizer, and a second electrical contact contacting a fourth electrical contact of the atomizer. Information obtained using the detection circuit is affected by stress applied to the first to fourth electrical contacts when attaching the atomizer to the holding portion.
