One container system includes a transparent display, a projector for providing image data on the display, and a floor defining part of a watertight cavity. The display is non-perpendicularly angled from horizontal and has proximal and distal ends. And a closure device is provided for use with a watertight container. The closure device is configured to selectively seal an opening in the watertight container and includes coupling structure (a plug, a flange, and/or threading) for selectively coupling the closure device to the watertight container to seal the opening. The closure device further includes non-transitory computer memory, at least one sensor, and a processor in data communication with the memory and the at least one sensor.

A removable hat device for a motor vehicle roof is disclosed, having a base housing, a tubular guide, a hat cover body, a hat base, a central cylindrical support column, and an elongated bolt. The base housing includes plurality of rubber coated magnetic feet adapted to removably magnetically adhere to the roof of the motor vehicle. The base housing further includes an upstanding cylindrical sleeve. The tubular guide is fixed to the base housing. The hat cover body is attached to the base housing via a circular ring shaped platform having a plurality of spokes extruding from the central cylindrical support column. The central cylindrical support column is telescopically received in the upstanding hollow cylindrical sleeve of the base housing. The elongated bolt removably extends through the tubular guide, the hat cover body, the upstanding cylindrical sleeve, and locks at the central cylindrical support column.

The invention relates to an arrangement (100) comprising a lighting system (110) and a target object (120), wherein the lighting system (110) is arranged to illuminate a target surface of the target object (120) with a primary light output (111) and with a secondary light output (112). Each of these light outputs has an illumination spectrum representing a color. The two illumination spectra are different, but the two colors are substantially the same. The target surface has a first target surface area and a second target surface area. When the first and second target surface areas are illuminated with the primary light output (111), they have a contrast that is lower than when they are illuminated with the secondary light output (112). The arrangement of the invention can be used for atmosphere creation or for attracting attention to the target object (120).

An object is to provide a transparent screen which can clearly project and display an image without degradation of transmission visibility and a method for manufacturing the transparent screen.

A thin film 4 in which a large number of regular hexagonal hole portions 3 that are identical to each other are opened, in a transparent sheet 2, in a web-like manner is applied to a transparent screen 1. The regular hexagonal hole portions 3 are segmented with web-like line portions 6 formed by connecting the sides 5 of the adjacent regular hexagonal hole portions 3 so as to have an even width, image light projected from a projector 7 is reflected off the web-like line portions 6 and is shown on the transparent screen 1 and a background on the back surface side of the transparent screen 1 can be visually recognized through the regular hexagonal hole portions 3.
