Abstract: A refrigerated appliance can include a refrigeration system; a first refrigerated portion; a second refrigerated portion positioned below the first refrigerated portion and horizontally adjacent to an evaporating unit of the refrigeration system, the evaporating unit configured to supply air to each of the first refrigerated portion and the second refrigerated portion; a first sensor configured to measure a temperature of air circulated within the first refrigerated portion; a second sensor configured to measure a temperature of air received within the second refrigerated portion; and at least one controller configured to control, at least in part, the temperature of the air received within the first refrigerated portion within a first predetermined temperature range and the temperature of the air received within the second refrigerated portion within a second predetermined temperature range.

Abstract: A method of using a refrigerated appliance can include regulating a temperature of a first insulated enclosure of a first refrigerated portion of the appliance within a first predetermined temperature range, the appliance including the first refrigerated portion and a second refrigerated portion positioned below the first refrigerated portion; moving a closure device of the first refrigerated portion from an open position to a closed position, the closure device configured to selectively cover and limit leakage of air from an ambient environment to and from a second insulated enclosure of the second refrigerated portion; and adjusting a predetermined temperature range of the first insulated enclosure by a predetermined offset value based on a sensor signaling that the closure device is in the closed position.

Abstract: Formulations, articles and methods for the detection and/or qualification of ultraviolet light. A chemical formulation containing a tetrazolium or formazan complex is used to make a UV sensitive compound. The formulation is used to form a chemical indicator comprising a substrate with the formulation impregnated on or in the substrate. The substrate may be any suitable material and may be coated, uncoated, or laminated. The formulation may be coated on or inserted into a substrate and will form a UV detecting indicator when applied thereto. Depending upon its composition, the formulation will undergo a color change on exposure to different types of ultraviolet radiation, such as UVA, UVB or UVC, and the color change can be correlated to the length of exposure. The indicator can be used to detect and evaluate exposure to ultraviolet light in a variety of settings depending on the specifics of the formulation.
