A projection device is provided, including a main body, a cover body, a light-emitting assembly, a film assembly, and an imaging assembly. The cover body is movably connected to the main body. The light-emitting assembly is configured to emit light signals. The film assembly is disposed on a transmission path of the light signals. The imaging assembly is configured to image the light signals after passing through the film assembly, when the cover body covers the main body, the imaging assembly is disposed on one side of the film assembly facing away from the light-emitting assembly. The light-emitting assembly and the film assembly are disposed in the main body, and the imaging assembly is disposed in the cover body. The projection device enables improved user convenience.

An image presentation system for an amusement park includes a first display with an opening extending therethrough, wherein at least a portion of the first display is viewable from a viewing area, a movable arm, wherein the movable arm is positioned within the opening, a second display supported by the movable arm and offset from the first display, wherein the second display conceals the opening from the viewing area, and a controller configured to provide a first image via the first display and a second image via the second display such that the second image comprises an image effect that accounts for the offset and coordinates with the first image to present as though the first image and the second image are a single image displayed by the first display.

An inflatable chamber has a chamber wall, sealing panel, and seal flap. A chamber zipper is formed in the chamber wall, and a panel zipper is formed in the panel. The panel has a panel perimeter that is sealed to said chamber wall about the chamber zipper in an airtight manner to form a pocket between the chamber wall and the panel. The seal flap is positioned in the pocket to provide an airtight seal at the chamber zipper.

A system comprises a stowable support surface comprising a translucent display. The stowable support surface is configured to be moveable between a first position and a second position. The system further comprises at least one projector configured to project an image on the translucent display. The at least one sensor is configured to indicate a current position of the stowable support surface. The system further comprises a projector controller in communication with the at least one projector and the at least one sensor. The projector controller is programmed to: instruct the at least one projector to project at least one image on the translucent display when the stowable support surface is in the first position; receive a signal from the at least one sensor indicating that the stowable support surface is in between the first position and the second position; and instruct the at least one projector to halt projection of images.

A method for authenticating the user of device (110) is proposed. This method is: a. A projector (112) projects multiple light beams onto the user through a display (114), the multiple light beams including a first light beam and a second light beam, and the display (114) directs the first light beam and the second light beam to illuminate at least partially overlapping areas of the user, step (130) b. A step (132) of generating a pattern image showing the projection of multiple light beams onto the user, c. A step (134) of extracting biological data from the pattern image, d. A step (136) that allows the user to perform an operation on a device (110) that requires authentication based on the biometric data, Includes.

An embodiment discloses an optical device comprising: a plurality of lenses; a barrel in which the plurality of lenses are disposed; a first light guide disposed in the barrel; and an opening formed on a side surface of the barrel, wherein the first light guide is disposed between two lenses from among the plurality of lenses, and the opening overlaps the first light guide in a direction perpendicular to an optical axis.
