An atomization unit has a tube-shaped furnace, and heats and atomizes a sample injected into the furnace. A light source unit emits light having a wavelength to be measured toward the atomization unit such that light passes through the furnace. An optical system transmits the light having the wavelength to be measured, of light passing through the furnace. A detection unit detects the light transmitted by the optical system. A light transmission plate is provided at a position in an optical path of the light passing through the furnace toward the detection unit, to obliquely cross an optical axis of the light. An image capturing unit is arranged outside the optical path, and captures an image inside the furnace by receiving light reflected by the light transmission plate, of the light passing through the furnace.

A flame analytics system that may incorporate a burner, one or more sensors at the burner, a historical database connected to the one or more sensors, a model training module connected to the historical database, and a runtime algorithm module connected to the one or more sensors and the model training module. The runtime algorithm may compare realtime data from the one or more sensors and historical data from the model training module in accordance with a machine learning algorithm. The system may further incorporate a fault detection module connected to the runtime algorithm module, a fault diagnostics module connected to the fault detection module, and an enunciator connected to the fault detection module. The one or more sensors may also include having video or acoustic sensitivity of combustion in the burner.

A refrigerator door and a manufacturing method of the same are disclosed. The refrigerator door includes a front panel that includes a first through hole and an input unit, a door liner, an upper cap decoration unit configured to seal an upper side of a first space defined between the front panel and the door liner, a frame attached to an inside of the front panel and defining a second space, a display assembly provided between the frame and the front panel and configured to emit light through the first through hole, and a touch sensor assembly provided between the frame and the front panel, the touch sensor assembly being fixed to a rear of the front panel at a position that corresponds to a location of the input unit. The upper cap decoration unit includes a communication hole for communicating with the second space and includes a cap cover.

An oven can include an oven body including a set of interior panels. A set of exterior panels are spaced from the set of interior panels such that a channel is defined between the set of interior panels and the set of exterior panels. The set of interior panels includes an interior panel peripheral wall and an interior panel top wall that at least partially define a cooking cavity. Each interior panel of the set of interior panels has an inner surface and an outer surface. Insulation is located in at least a portion of the channel. The oven further includes an imaging device with a field of view including at least a portion of the cooking cavity.
