Gas cooktops disclosed herein may include a proportional solenoid valve controlling gas flow to a gas burner, where the proportional solenoid valve has a continuously variable range of positions. A user interface (UI) element associated with the proportional solenoid valve may be utilized to control a linear voltage regulator having a continuously variable output voltage. The output voltage of the linear voltage regulator is coupled to a solenoid of the proportional solenoid valve, such that the gas flow to the gas burner has a linear relationship with the output voltage of the linear voltage regulator.

A cooking appliance for heating food comprises a remote control for controlling the cooking appliance remotely. According to the present invention a distance control is provided for detecting the distance between the remote control 10 or a user and the cooking appliance.

The present invention discloses an outdoor gas heater, comprising an outer cover, an outer cover side baffle, a gas injection pipe, a ceramic burner, a body box, a control box connecting support frame, a control box sealing plate, a control box, a wall-mounted bracket and a long open a flame connecting pipe. Four ceramic burners are fixed side by side in the body box, a gas injection pipe is fixed on the lower side of the body box, and a gas injection pipe is sealingly connected to the four ceramic burners; the outer open end of the body box is locked to the outer cover, and the side of the body box opposite to the outer opening thereof is locked to the control box connecting support frame. The control box connecting support frame is a U-shaped structure, and side wall of which is locked on both sides of the control box, and the outer side opening of the control box is locked to the control box sealing plate; the side of the control box opposite to the outer opening is locked to the wall-mounted bracket. The structure is reasonable in design and convenient to use, and its installation and use is very convenient and safety is greatly improved; moreover, it can save energy and maintain the demand for power supply for a long time.

A gas burner assembly and a method of operating the same are provided. The gas burner assembly includes a gas burner and a fuel regulating device for providing a flow of fuel to the gas burner to heat a cooking utensil. The method is a closed loop cooking method that includes monitoring the temperature of the cooking utensil and adjusting the power output of the burner accordingly to drive the utensil temperature to a target cooking temperature or profile. However, the burner power is limited to a maximum fuel flow rate, e.g., to ensure safe operation and to prevent the flames from the gas burner from engulfing the sides of the cooking utensil.

A wave guide assembly for a control and diagnostic system for a machine includes a housing defining an exterior surface and an internal cavity extending between distal ends. At least one wave guide within the internal cavity defines a wave propagation passage for at least one wave form signal. At least one conductor within the internal cavity is separate from the wave guide. A control and diagnostic system for a machine and a gas turbine engine are also disclosed.

A flame show is responsive to an audio input signal such as music. A base unit including an analog base unit controller circuit is arranged to receive an audio input signal and generate an analog control signal that is responsive to the audio input signal. The analog control signal is distributed, by wire or wireless, to one or more flame display units such as a tiki torch. Each flame display unit has a fuel source, and a proportional valve for controlling an amount of fuel supplied to a burner. Preferably, the control signal controls a gate terminal of a MOSFET semiconductor device, which in turn is coupled to control current in the proportional valve each each unit. By deploying multiple flame display units, all coupled to the same base unit, all of the flame display units contribute synchronously to the overall flame show.
