    Abstract: Information display device comprising a legend face (12) with a two-dimensional array of individually operated pixels (14). The legend face comprises an opaque sheet having a front side (16) to be presented to an observer and a back side (18). Each pixel comprises an aperture (22) in the opaque sheet and an associated shutter (24), the aperture being partially-light-transmissive and preferably retroreflective, the shutter being opaque and having first and second faces which are of visually distinctive appearance with the second face being retroreflective. Each shutter is selectively settable to a first state in which it occludes its associated aperture such that the first face (26) of the shutter is presented so as to be visible to an observer, and a second state in which it exposes its associated aperture such that the shutter's second face (28) and associated aperture are presented so as to be visible to an observer. The device further comprises means (30) for selectively positioning the shutters in the two states and at least one light source (20) disposed on the rear side of the opaque sheet.

    Abstract: An integrated retroreflective data communication display (2) for visual and electromagnetic communication is described. The display (2) may be configured as an integrated retroreflective electronic license plate, with printed visual information (4), similar to the information printed on traditional license plates, on retroreflective sheeting (6). An antenna network (8) is integrated within the license plate for electromagnetic communication and may be connected to external electronic modules. The display may also be configured as an integrated retroreflective electronic road sign (140), also providing visual and electromagnetic information in a unitary structure.

    Abstract: Retroreflective assembly comprising: a) a transparent globule having a first, uncoated part-spherical surface portion for reception of incident light; a second, substantially flat surface portion opposite the first surface portion; and a third, toroidal surface portion intermediate the first and second surface portions, the toroidal surface having a radius of curvature smaller than the radius of curvature of the first part-spherical surface portion; b) a monolayer of externally reflecting transparent microspheres for focusing and retroreflecting light beams incident upon the first surface portion and which have passed through the globule, the monolayer being applied to at least a part of the toroidal surface portion; and c) a layer of diffuse reflecting pigment disposed behind the monolayer of microspheres. Optionally, a space coat is interposed between the monolayer and the diffuse reflecting pigment. In some embodiments, fluorescent pigment isused.
