摘要： A directionally active projection device is described that includes a planar display providing a pattern of information. The planar display includes regions of light transparency and regions for blocking light transmittance. The directionally active projection device also includes a lens arranged adjacent to the planar display, and a collection of light sources arranged as an array in a focal plane of the lens. Also described are methods of controlling directionally active projection devices.

摘要： Provided herein is a retroreflective article comprising a retroreflective film and a plurality of isosceles triangular pyramid prisms embossed on the back surface of the retroreflective film. The prisms are configured such that the article reflects an incident light beam into two reflected light beams that are offset from and on opposite sides of the incident light beam. The two reflected light beams can provide two viewing zones located at different positions relative to the incident light beam source.

摘要： Methods of making tiled articles and molds used to make retroreflective articles. The methods include forming a prism array on a master substrate and forming a replica of the master. A reference edge is formed on the replica, thereby reducing the size of the prism array, yet maintaining a lateral dimension of the replica to maintain ease of handling of the replica. The replica is copied and the reference edge on the copied tiles are exposed, such that the reference edge can be mated and secured face-to-face with a reference edge on other tiles in order to form a tiled article. The tiled article is used as a mold to produce retroreflective articles or can be further duplicated and mated to form larger tiled articles to be used as molds. Tiled articles used as molds and retroreflective articles produced from the molds are also disclosed.
摘要翻译： 用于制造回归制品的瓷砖制品和模具的方法。 所述方法包括在母板上形成棱镜阵列并形成母板的复制品。 在复本上形成参考边缘，从而减小了棱镜阵列的尺寸，同时保持了副本的横向尺寸以保持复制品的易于处理。 副本被复制并且复制的瓦片上的参考边缘被暴露，使得参考边缘可以与其他瓦片上的参考边缘面对面地配对和固定，以形成平铺的物品。 平铺制品用作模具以制造回射制品，或者可以进一步复制和配合，以形成用作模具的较大的瓷砖制品。 还公开了用于由模具制造的模具和回射制品的平铺制品。

摘要： Various geometries are described for forming retroreflective structures in polymeric sheets or films. The geometries enable venting of volatile gases that can otherwise become trapped between the embossing surface and the polymeric sheet or film. The geometries are incorporated in tooling belts or other pattern forming surfaces.
