A cloaking device includes an object-side, an image-side, a cloaked region (CR) between the object-side and the image-side, and a reference optical axis extending from the object-side to the image-side. An object-side CR reflection boundary, an object-side half-mirror, and an object-side color filter are positioned on the object side and an image-side CR reflection boundary, an image-side half-mirror, and an image-side color filter are positioned on the image-side. The object-side half-mirror and the object-side color filter are spaced apart from and positioned generally parallel to the object-side CR reflection boundary, and the image-side half-mirror and the image-side color filter are spaced apart from and positioned generally parallel to the image-side CR reflection boundary. Light from an object located on the object-side of the cloaking device and obscured by the CR propagates via three optical paths to form an image of the object on the image-side of the cloaking device.

A side view mirror assembly for use by an operator of an vehicle including a mirror housing mounted to an outer surface of the vehicle, a side view mirror including a reflective surface, the side view mirror being mounted in the mirror housing so that the side view mirror reflects items disposed rearwardly of the vehicle, wherein the side view mirror is configured for adjustment with respect to the mirror housing so that an angle of the mirror with respect to the mirror housing is selectively changeable, and a first marking that is visible on the reflective surface of the side view mirror so that a reflection of a portion of the vehicle falls within a first portion of the reflective surface that is defined by the first marking.

A display image to be displayed on a display unit is obtained in accordance with motion of a viewpoint of a driver, on the basis of a captured image obtained by capturing an image on a rear side from a vehicle, when a line-of-sight of the driver is in a certain region including the display unit. For example, the display image is obtained in accordance with a deviation of a viewpoint position of the driver from a reference viewpoint position. For example, the reference viewpoint position is updated on the basis of a long-term fluctuation of the viewpoint position. For example, the reference viewpoint position is not updated when a line-of-sight of the driver is in a certain region including a display unit that displays a display image.

A mirror adjustment assistance system for trucks having as part of a vehicle body at least a cabin (3) having a front side with respect to an intended main direction of travel, a driver side, and a co-driver side. At least three adjustable mirrors (5, 7, 9, 11, 13, 19) are attached to an exterior of the vehicle body or cabin (3), each of the at least three adjustable mirrors (5, 7, 9, 11, 13, 19) has an aiming marker (43, 45, 59, 61, 65, 69) on or adjacent its reflective surface. At least two vehicle body target markers (41, 57, 63, 67) are positioned on an exterior surface of the vehicle body (3), and at least a single one (41; 57) of the at least two vehicle body target markers is associated with two of the at least three mirrors (5, 9; 7, 11). Any aiming marker (43, 45, 59, 61, 65, 69) of the at least three adjustable mirrors (5, 7, 9, 11, 13, 19) can only be aligned with a single one of the at least two vehicle body target markers (41, 57, 63, 67).

A display device and a vehicle door include a projection surface provided on a surface on a vehicle interior side of a door body provided at a vehicle, a projector configured to project an image, and a holding unit configured to hold the projector at the door body, in such a positional relationship that the image from the projector is projected on the projection surface. Thus, the display device and the vehicle door can effectively project an image appropriately on the vehicle door body.

A cloaking device includes an object-side, an image-side, a cloaked region (CR) between the object-side and the image-side. An object-side CR reflection boundary and a plurality of object-side color filters are positioned on the object side and an image-side CR reflection boundary and a plurality of image-side color filters are positioned on the image-side. The plurality of object-side color filters are spaced apart from and positioned generally parallel to the object-side CR reflection boundary, and the plurality of image-side color filters are spaced apart from and positioned generally parallel to the image-side CR reflection boundary. The plurality of object-side color filters and the plurality of image-side color filters may be co-planar and light from an object located on the object-side of the cloaking device propagates via at least two optical paths to form an image of the object on the image-side of the cloaking device.

A cloaking device includes an object-side, an image-side, and a cloaked region (CR) between the object-side and the image-side. An object-side CR reflection boundary, an object-side half-mirror, and an object-side external reflection boundary are positioned on the object-side, and an image-side CR reflection boundary, an image-side half-mirror, and an image-side external reflection boundary are positioned on the image-side. The object-side half-mirror and the object-side external reflection boundary are spaced apart and generally parallel to the object-side CR reflection boundary, and the image-side half-mirror and the image-side external reflection boundary are spaced apart and generally parallel to the image-side CR reflection boundary. Light from an object located on the object-side of the cloaking device and obscured by the CR is redirected around the CR via two optical paths to form an image of the object on the image-side of the cloaking device.

A cloaking device includes an object-side, an image-side and a cloaked region between the object side and image-side. An object-side half Fresnel lens, an image-side half Fresnel lens and a planar reflection boundary positioned between the object-side half Fresnel lens and the image-side half Fresnel lens are included. The object-side half Fresnel lens and the image-side half Fresnel lens each comprise an inward facing surface and an outward facing Fresnel surface. The planar reflection boundary comprises an inward facing mirror surface. Light from an object positioned on the object-side of the cloaking device and obscured by the cloaked region is redirected around the cloaked region by the object-side half Fresnel lens, planar reflection boundary and image-side half Fresnel lens to form an image of the object on the image-side of the cloaking device such that the light from the object appears to pass through the cloaked region.

A cloaking device includes an object-side, an image-side and a cloaked region between the object-side and the image-side. An object-side polyhedron with an entrance side and an exit side parallel to the entrance side is positioned on the object-side and an image-side polyhedron with an entrance side and an exit side parallel to the entrance side is positioned on the image-side. The entrance side of the object-side polyhedron is oriented relative to a reference optical axis extending between the object-side and the image-side at an acute angle and the exit side of the image-side polyhedron is oriented relative to the reference optical axis at an oblique angle equal to 180. Light from an object positioned on the object-side of the cloaking device is redirected around the cloaked region, without total internal reflection of the light within the object-side polyhedron or the image-side polyhedron.
