  • Patent number: 9499934
    Abstract: Laundry treating appliances and methods of controlling the same to determine an end-of-cycle condition are disclosed. An example method of operating a laundry treating appliance having a treating chamber in which laundry is received for treatment, and a heated air system having a supply conduit coupled to the treating chamber and an exhaust conduit coupled to the treating chamber includes supplying heated air to the treating chamber via the supply conduit, exhausting air from the treating chamber via the exhaust conduit, repeatedly determining exhaust air temperatures of the air exhausted from the exhaust conduit, determining a windowed derivative of the exhaust air temperature values, determining a zero crossing of the windowed derivative, and initiating the termination of the supplying of heated air in response to the determination of the zero crossing.

  • Publication number: 20160316955
    Abstract: A method of boil and boil-dry detection for cooking appliances. The method includes the steps: detecting vibrations that correspond to cookware situated on a burner assembly; generating a vibration signal based on the vibrations; and performing signal processing on the vibration signal. The method also includes the steps: collecting vibration data related to the vibration signal; and detecting boiling and boil-dry conditions for a liquid contained within the cookware based at least in part on an evaluation of the vibration data.

  • Patent number: 9395078
    Abstract: A cooking sensor system that includes a burner assembly; and a vibration sensor assembly configured to generate a vibration signal that corresponds to vibrations of cookware situated on the burner assembly. The cooking sensor system also includes a processor to receive the vibration signal and determine at least one of a boiling condition and a boil-dry condition for a liquid contained within the cookware, wherein the determination is based at least in part on the vibration signal. The cooking sensor system further includes an indicator element coupled to the processor to indicate the at least one of a boiling condition and a boil-dry condition. The cooking sensor system may also include a control element coupled to the processor to operate the burner assembly based at least in part on the at least one of a boiling condition and a boil-dry condition.
