Abstract: Provided is an apparatus and method for protecting against unsafe electric current conditions. An example method includes accessing a selected operating mode for a heating element of the electric grill using at least one user input device of the electric grill, the heating element connected to a voltage line and a neutral line; measuring, using a temperature probe, a temperature of the heating element; estimating an ambient temperature at a location within a cook box of the electric grill spaced apart from the heating element, the estimation of the ambient temperature based on the measured temperature of the heating element; and using the estimated ambient temperature to determine when a target temperature corresponding to the selected operating mode is reached.

Abstract: Provided is an apparatus and method for a digital power supply that can provide independent power control for two or more electrical loads. Some disclosed embodiments provide continuous, variable power and other disclosed embodiments provide discrete power levels. Disclosed embodiments may reduce the magnitude of harmonic currents and/or flicker introduced into a power system. Embodiments include a microprocessor that delivers power to electric loads using phase-controlled AC current. In some embodiments, the microprocessor may calculate a power array corresponding to a requested power for each electric load. Logic is provided for populating the power array in a pattern that reduces the magnitude of harmonic currents and flicker. Portions of the disclosure include a band controller for delivering power to achieve and maintain a desired target temperature, and a wireless controller for controlling temperature from a remote device.

Abstract: Methods and apparatus to indicate presence of a flame are disclosed. An example gas grill includes a burner tube having apertures to emit a fuel for combustion, an ignition element to cause ignition of the fuel emitted from the apertures of the burner tube, a flame sensor to detect the presence of a flame associated with the combustion of the fuel emitted from the apertures of the burner tube, and flame sense circuitry including a flame signal accessor to access a flame sense signal from the flame sensor, and a terminal to output an indication of the presence of the flame, the indication of the presence of the flame output without respect to an open or closed state of a lid of the grill.

Abstract: Pellet grills including a control system that implements, manages, and/or controls various ignition-based protocols and/or processes are disclosed. An example pellet grill includes a cooking chamber, a burn pot, an ignitor, and a controller. The ignitor extends into the burn pot and is configured to ignite pellet fuel located within the burn pot. The controller is configured to command the ignitor to activate during a first duration. The controller is further configured to determine, following expiration of the first duration, whether a temperature of the cooking chamber has reached a threshold temperature. The controller is further configured, in response to determining that the temperature has not reached the threshold temperature, to command the ignitor to activate during a second duration.

Abstract: Provided is an apparatus and method for protecting against unsafe electric current conditions. A protections circuit may be used in a device, such as an electric grill, that has one or more electric loads, such as heating elements. The protection circuit may protect against various failure scenarios, including, without limitation, instances of ground fault, over current, driver failure, and failure of a microprocessor. In response to a failure, the protection circuit may trip a latch relay or disable a triac driver to stop current from flowing.
