An illuminated vehicular sign is provided including a vehicle and luminescent planar sheet. The luminescent planar sheet is constructed to provide illuminated alpha-numeric characters which are mounted to the horizontal planar surfaces of a vehicle. The alpha-numeric characters are mounted substantially horizontally so as to be seen from the air such as by helicopters or planes. The illuminated vehicle sign includes a switching system electrically connected to the luminescent planar panels for selectively controlling the transfer of power from said power source to the luminescent planar panels. The switching system including one or more adjustable variable resistors electrically connected to the luminescent planar panels for allowing one to selectively adjust the wattage provided to them.

The invention discloses a backlit tension fabric popup display, including an exhibit grid frame, backlit grooved straight rods and a plurality of roller-shutter-style LED light bars. A plurality of roller-shutter-style LED light bars are suspended on the light bar hooks between the upper and lower X-shaped pull rods. Four sides on one plane or eight sides on two planes of the exhibit grid frame are all connected to the backlit grooved straight rods by the corner grooved plastic parts at both ends. A display is formed by inserting the silicone strips at the edges of the display into the corresponding grooves of the backlit grooved straight rods. The backlit tension fabric popup display and the LED light bars are perfectly combined, without the black rim, folds or a light leak. In addition, single or double planes are chosen as needed.

Embodiments herein describe systems and methods for visually identifying a wheeled robot and associating the wheeled robot with a company or brand. Some embodiments provide a cover, casing, or skin that may be removably attached to the wheeled robot. The casing may feature a pattern, logo, or visuals that are associated with the company. The casing may further conform to features of the movable robot such that the casing does not impede the robot from moving and performing functions, such as transporting objects. The casing may further have a flap that removably attaches to the casing to allow access to the wheeled robot.

An illuminated sign comprises a source of blue light; a quantum dot-containing film that produces green light when illuminated by the source of blue light; and, a patterned blue cutoff filter in optical communication with the quantum dot-containing film configured to allow a mixture of excess blue light from the source of blue light and green light from the quantum dot-containing film to pass through the pattern. The mixture of blue light and green light produces a pseudo white light. The illuminated sign may thus comprise pseudo white letters and/or graphics on a luminous green background.
