An aircraft projection device includes a projector that displays an image by projecting the image onto a floor surface of a passage in an interior of an aircraft; and a controller that controls the projector to display the image onto the floor surface of the passage in the interior of the aircraft.

A restaurant service robot moves to a target table along a movement path in a state in which a plurality of trays, on which food can be placed, are arranged to be vertically spaced a predetermined distance apart from each other to form a multi-layer structure and food is accommodated on the trays, so as to induce, through a voice or a display, a customer to take the food. The restaurant service robot comprises a communication function unit, an image receiving unit, a path search unit, one or more tray seating units, an information display unit, and an external input unit.

An optical projection device for projecting a linear image is disclosed. Light emitted by an array of light emitting diodes arranged along an array axis is focused in at least a direction perpendicular to the array axis and diffused in a direction parallel to the array axis, thereby generating a linear image in which light from adjacent light emitting diodes is spatially overlapped. In some embodiments, the focusing and diffusion of the light is performed by a Fresnel lens and a lenticular lens, respectively. The optical projection device may be employed to virtually mark a surface, such as a floor in an industrial setting. High power light emitting diodes may be employed to generate a linear image having an illuminance of at least 4000 lux that is focused to a distance between 7.5 and 20 feet.

An illumination device may include, but is not limited to: a shell portion; and a light projection device disposed at least partially within the shell portion, the light projection device including: at least one light source operably couplable to a power source; and at least one diffraction grating configured to distribute a light beam generated by the at least one light source onto an interior surface of the shell portion.

The headwear with integrated image projector comprises an image projector and a hat. The hat may be adapted to be worn upon a head of a wearer. The image projector may be coupled to the hat. The hat may project a projected image from the hat onto a viewing surface using the image projector. In some embodiments, the image projector may be coupled to a first position of the hat and the viewing surface may be a second position of the hat. As a non-limiting example, the first position may be the front of the hat bowl and the second position may be the top surface of the hat brim. In some embodiments, the hat having the image projector may comprise a wireless communication interface such that the image projector may communicate with an application program running on a wearer's smartphone.

A water-globe decoration light-and-shadow pedestal structure includes a pedestal to which a water-globe decoration is attachable. The pedestal is provided, in an interior thereof, with light-emitting elements. The pedestal has a wall that is formed with at least one hollowed pattern. The water-globe decoration is of a light-transmitting three-dimensional configuration and has a sealed interior space that receives and holds therein a flowable liquid. Height differences of the light-emitting elements relative to the at least one hollowed pattern allows light to pass through the at least one hollowed pattern of the pedestal to project a shadow of the at least one hollowed pattern onto an object outside the pedestal, so as to generate a lighting and shadowing visual effect that is rich and shows variation of layering.

An annular multimedia stadium goalpost and multipurpose target display system. The system includes a rear support-and-multimedia assembly for supporting the net and producing audible and visual effects. The system also includes a at least one annular frame and a primary projector. The rear support-and-multimedia assembly includes a support assembly and a multimedia bar system. The support assembly maintains the annular frame and the multimedia bar system in an orientation that facilitates playing sports and projecting information. The multimedia bar system includes a plurality of lights, a plurality of first speakers, a plurality of sponsor display panels, a retractably screen assembly, and a retractably underground projector in order to audible and visually convey content regarding the sports game and advertisements to the audience. The system also includes an annular display, and a multitude of rangefinder laser-detector video cameras to track, record, and present gameplay live.
