  • Patent number: 11920289
    Abstract: A heating device of a clothes drying treatment device executes an on or off operation in a temperature interval. When the temperature in a drum reaches an upper limit value TDx of the temperature interval under an action of the heating device, the heating device is turned off and the heating device stops heating. The upper limit value TDx decreases as a number of off times x of the heating device increases. Accordingly, a higher initial off temperature is adopted for the heating device, the temperature in the drum rapidly increases to the drying temperature, a preheating time is shortened, and a certain coefficient is multiplied in following control parameters controlling on or off of the heating device. The coefficient is related to the number of on-off times, and the effect is achieved that the off temperature of the clothes dryer gradually decreases as the number of on-off times increases.

  • Patent number: 11916406
    Abstract: A wireless power system has a wireless power transmitting device and a wireless power receiving device. The wireless power transmitting device may include a coil and wireless power transmitting circuitry coupled to the coil. The wireless power transmitting circuitry may include impulse response measurement circuitry that measures the inductance of the power transmitting coil and the quality factor of the power transmitting coil. The measured inductance and quality factor may subsequently be used to determine a position of the wireless power receiving device relative to the wireless power transmitting device. The determined position of the wireless power receiving device relative to the wireless power transmitting device may be used to estimate an expected power loss associated with the power transmitting coil. The power transfer operations may be adjusted based on expected and actual power losses.
