Image acquisition method for microbolometer thermal imaging systems
A method and system for imaging a target scene using a microbolometer array having multiple lines of microbolometer pixels are disclosed. Each line is switchable between an exposed state and a shielded state, where the line is exposed to the target scene and a reference scene, respectively. The method may include alternating between generating a target frame of the target scene and generating a reference frame of the reference scene, each of which in a rolling shutter mode. The method may also include, concurrently with the generating steps, alternating between sequentially shielding each line after its readout in the exposed state for its next readout in the shielded state, and sequentially exposing each line after its readout in the shielded state for its next readout in the exposed state. The method may also include adjusting the target frames using the reference frames to generate thermal images of the target scene.

Method and device for measuring internal temperature of heap fermentation based on infrared temperature measurement
A device for measuring the internal temperature of heap fermentation includes an infrared thermal imaging camera, a distance detection camera, and a controller. The infrared thermal imaging camera obtains a temperature distribution image of a surface of a fermentation heap. The distance detection camera obtains a distance between the surface of the fermentation heap and the distance detection camera. The controller matches the temperature distribution image of the surface of the fermentation heap with the distance between the surface of the fermentation heap and the distance detection camera, performs semantic segmentation on the image after matching is completed, extracts a three-dimensional (3D) contour temperature map of the surface of the fermentation heap, corrects a surface temperature of the fermentation heap, and predicts an estimated internal temperature of the fermentation heap, such that the internal temperature of the fermentation heap is effectively and accurately predicted.
Methods and apparatus for controlling a cooking appliance
A cooking appliance includes a cooktop having at least one heating element for heating a cookware member on or to be placed on the cooktop, the at least one heating element being adjustable between a working-power level wherein the at least one heating element is energized to generate heat and a zero-power level wherein the at least one heating element is not energized. The cooking appliance further includes a temperature sensor configured to detect a temperature or rate of temperature change of a cooking element. The cooking appliance further includes a control device configured to adjust the at least one heating element from the working-power level to the zero-power level based on the temperature or rate of temperature change of the cooking element. The at least one heating element will remain at the zero-power level until a user intervenes to re-energize the at least one heating element.
