Abstract: In one embodiment, a method includes accessing, by a computing device, a thermal image of a space within a cooking apparatus, wherein the space contains a food item. The method further includes segmenting, by a computing device and based on the thermal image, the food item in the space from the food item's environment.

Abstract: Methods of manufacturing circuit boards and circuit boards formed thereby to have a surface that is configured to receive circuitry and a notch of a selectable configuration in a lateral edge along the surface of the circuit board boards, and where the selectable configuration is configured to convey identifying information relating to the circuit boards. Such a circuit board can be produced from a panel containing one or more circuit boards, wherein at least one circuit board has a border adjoined and defined by a partition feature that is configured to enable the circuit board to be physically separated from other portions of the panel. Notches having the same of varying selectable configurations may be formed on the at least one circuit board during the manufacturing of the circuit board.
