AI Technical Summary
Technical Problem
Existing burner monitoring systems fail to accurately detect when electric burners are left on without cookware, leading to potential safety hazards and inefficiencies.
Method used
A burner monitoring system using time-of-flight sensors that emit infrared light to detect active electric burners and determine if they are uncovered or partially uncovered by analyzing the ratio of reflected light data compared to emitted light, generating alerts when differences exceed predefined thresholds.
Benefits of technology
The system effectively identifies uncovered or partially uncovered burners, reducing safety risks and energy waste by alerting users, thereby enhancing safety and efficiency.

Abstract
A monitoring system with burner-left-on detection includes a matrix-style time-of-flight sensor defining a detection field formed from cells. The matrix-style time-of-flight sensor includes an emitter for emitting infrared light and receivers for receiving light data including the infrared light. Burners in the detection field are configured to emit infrared light when active. A controller is configured to compare the light data to the infrared light emitted by the emitter for each of the plurality of cells, determine if the light data for any of the plurality of cells is greater than the infrared light emitted by the emitter, and determine that at least one of the burners is an active burner and at least partially uncovered when the light data for one or more of the cells associated with the active burner is greater than the infrared light emitted by the emitter.
