An illumination system has a display area and a main light source arranged above the display area, and an auxiliary light source arranged above the display area. The illumination system and the lamp through the visual optical superposition principle, provides brightness lighting by the main light source and provides different quantities of auxiliary light sources to flicker the subject. Consumers gain a better shopping experience as the gradient of the light changes so smoothly as to be imperceptible.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

An in-airport guitar kiosk and related methods for allowing air travelers an opportunity to relax and play guitar before or after flights (to improve the passenger journey) as well as the opportunity to try a novel travel guitar uniquely suited for air travel.

A shelf assembly for an enclosure includes a shelf panel having an upper surface, a lower surface, and an edge extending between the upper and lower surfaces. The edge includes front, rear, and side edges. A light housing is coupled to the shelf panel and includes one or more walls defining an interior. The light housing includes front, rear, and side portions disposed adjacent to the front, rear, and side edges of the shelf panel, respectively. A plurality of light sources received within the light housing to project light outwardly therefrom.

A reusable preservation and storage frame system is provided having a interlocking frame wall system of a non-off-gassing nature, such as aluminum, and includes a back panel and front lid, which provides for utilization of channels for connector systems, and internal support systems for a stackable storage frame, adaptable for storage of artwork of various dimensions.

A method for reducing sweating in a temperature-controlled display device includes receiving values of an ambient temperature, a door frame temperature, and relative humidity. The method can also include estimating a value of a dewpoint temperature using the values of the ambient temperature and the relative humidity. The method can also include determining control decisions for a door frame heater of the temperature-controlled display device using the value of the dewpoint temperature and the door frame temperature, and transitioning the door frame heater between an on-state and an off-state using the control decisions to maintain the value of the door frame temperature at or above the value of the dewpoint temperature.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

A modular shelving system includes a plurality of shelves, each shelf having a length and defining a first passage, a second passage, a first channel, and a second channel that each extend the full length of their respective shelf. The system also includes a plurality of bars, each bar defining a length and including a first bar opening at a first end and a second bar opening at a second end opposite the first end, and a plurality of connectors, each connector including at least two male portions, each male portion sized and shaped to be received in one of the first passage, the second passage, the first bar opening, and the second bar opening to interconnect each of the plurality of shelves and each of the plurality of bars.

An illuminable display assembly including (a) a housing having a base securable to a support surface, a platform detachably mounted to the base, and a generally enclosed interior bounded from above by the platform. The platform includes a plurality of illuminable windows spaced apart from each other therealong. The display assembly further includes (b) a plurality of retractable tethers mounted to the platform in the interior of the housing. The tethers fasten corresponding display containers to the platform and urge the display containers to predetermined positions adjacent corresponding windows. The display assembly further includes (c) a lighting system including one or more interior light sources in the interior of the housing for illuminating the windows and display containers from below.

A shelving system includes a shelving unit with at least one open sidewall that provides access to an interior of the shelving unit and one or more inserts that can be selectively connected to and disconnected from an interior of the unit in order to compartmentalize the interior of the unit. This enables a user to separate, sort and store items in the interior in an orderly fashion. The at least one open sidewall also serves to display the items stored in the unit. The shelving unit can be attached to a supporting wall in order to be located at desirable height to facilitate storage and display of the items stored therein.
