A vacuum insulated structure including a first cover member of a stamped unitary sheet defining a perimeter portion positioned at a first planar level and first rib formed in the unitary sheet extending to a second planar level spaced axially outward and disposed radially inward of the perimeter portion, a second cover member, and thermal bridge interconnecting the first cover member and the second cover member at the perimeter portions thereof to define an insulating cavity therebetween. The insulating cavity is a sealed cavity having a vacuum drawn therefrom, and the first rib defines a first portion of a path for air flow out of the sealed cavity during a vacuum draw process.

A refrigerator includes a cabinet forming a storage space, a main door that opens and closes the storage space while defining an opening part that is in communication with the storage space, a sub-door mounted to the main door and configured to open and close the opening part, the sub-door including a panel assembly for allowing selective viewing of an inside of the opening part, the injection port is provided at a lower side of the sub-door to direct an insulating foaming solution to a space in the sub-door, a detection device for detecting an operation of a user, a lighting unit inside the refrigerator that turns on based on user operation to allow selective viewing of the inner side of the opening part, and a display unit inside the refrigerator at a position corresponding to the panel.

A low-temperature storage device includes an inner vessel, an outer vessel about the inner vessel, a thermal insulation layer between the inner vessel and the outer vessel, and a single heat exchanger in thermal communication with an interior of the inner vessel and adapted to be connected to at least one of an evaporator in a closed-loop refrigeration circuit and an open-loop evaporator for an externally-supplied cryogen. The inner vessel can be a vacuum-insulated vessel, and the heat exchanger can be an internal heat exchanger including at least two fluid circuits: a first circuit with one external connection and one internal connection into the inner vessel and the second circuit with two external connections.

A bag holder for supporting a bioprocess bag during freezing includes a cover, a bottom, a frame, and at least one bag support. The cover, the bottom, and the frame form an enclosed space. The at least one bag support is disposed in the space. The cover and the bottom are made of metal. The frame has a first side, a second side, a front end, and a back end. Each of the cover and the bottom has a first bendable tab and a second bendable tab configured to bend over the front end from a longitudinal direction to a thickness direction, and a first arm and a second arm extending in the thickness direction and then in the longitudinal direction. Each of the first side and the second side includes at least one recessed portion extending in the longitudinal direction.

A home appliance includes a refrigerator. The home appliance includes a cabinet configured to define a storage space with a front surface opened, a door configured to open and close the storage space, and a speaker disposed on a top surface of the cabinet and configured to communicate with an external device, where the speaker includes a sound output portion configured to output sound. The sound output portion is inclined with respect to the top surface of the cabinet.

In an example, a transformable cargo container for use with ground and air transportation vehicles is disclosed. The cargo container includes a main container body defining a storage chamber therein and including at least one inlet. The cargo container also includes a transformable assembly coupled to the main container body and positioned at an exterior of the main container body. The transformable assembly includes one or more supplemental containers and one or more supply ducts, at least one of the supplemental container(s) being configured to house refrigeration equipment. The transformable assembly is movable between an aircraft configuration and a ground configuration. Based on the transformable assembly being in either the aircraft configuration or the ground configuration, the refrigeration equipment is configured to supply coolant into the main container body via the supply duct(s) and the inlet(s).

Methods of operating a refrigerator appliance are provided. The refrigerator appliance includes a cabinet defining a food storage chamber with a drawer slidably mounted within the food storage chamber. The refrigerator appliance also includes a sensor operable to detect an atmospheric condition within the food storage chamber of the drawer and a camera assembly positioned and configured for monitoring the drawer. The methods generally include obtaining an image using the camera assembly and analyzing the image to identify a first food item and a second food item in the food storage chamber of the drawer.

A semiconductor device includes functional circuits electrically coupled to each other and each coupled to a different thermal circuit. The different thermal circuits are configured to maintain different operating temperatures targeted for each corresponding functional circuit. One of the thermal circuits may use a cryogenic liquid to cool the corresponding functional circuit.

A method to control a refrigerator includes changing a transparent display assembly to be in a first or transparent state allowing an inner space of the refrigerator to be visible through the transparent assembly, a second or opaque state so as to conceal the inner space, and a third or a display state to display information on a display of the transparent assembly. The transparent display assembly includes a front panel, a rear panel, an outer spacer configured to maintain a first distance between the front panel and the rear panel, a display provided on a rear surface of the front panel, a light guide plate spaced apart from the display, and a first spacer configured to support the light guide plate and to maintain a second distance between the display and the light guide plate.
