  • Patent number: 10801722
    Abstract: A method for controlling operation of a fuel-fired heating appliance having a burner, a fuel flow control for controlling a fuel flow to the burner, and a combustion air blower for supplying combustion air to the burner, includes iteratively (1) determining the quality of combustion by sensing a flame at the burner and outputting a time-varying flame current signal that includes an ionization signal from the flame; sampling the flame current signal to obtain a time record of the flame current signal; using a Fourier transformation, transforming the time record into a frequency spectrum of frequency components that include frequency components of the ionization signal, the frequency spectrum having a spectrum shaped defined by various frequency components of the flame current signal; and determining whether the frequency spectrum indicates flame stability or instability.

  • Patent number: 10791892
    Abstract: A vacuum cleaning system includes a housing defining an inlet and an outlet, a motor connected to the housing and configured to generate air flow through the housing from the inlet to the outlet, and a debris container received within the housing in a first direction. The debris container includes a knob that is rotatable about an axis and includes a first cam and a second cam. Rotation of the knob about the axis causes the first cam to engage the housing and thereby move the debris container in the first direction, and causes the second cam to engage the housing and thereby move the debris container in a second direction.

  • Publication number: 20200158120
    Abstract: A circulator blower controller for a circulator blower of a heating, ventilation, and air conditioning (HVAC) system of a building includes an interface configured to receive a demand signal with an operating mode from a thermostat. A switching circuit selectively connects power to a tap of a motor of the circulator blower. A data store configured to store a mapping from a speed to the tap. For each tap, a processor observes power consumed by the circulator blower while power is connected to the tap by the switching circuit. The processor determines the mapping by sorting the taps based on observed power consumption. The processor selects a first speed based on the demand signal from the thermostat. The processor identifies a first tap from the mapping based on the first speed and generates the tap selection signal to control the switching circuit to connect power to the first tap.
