Abstract: An exemplary road traffic mirror includes a casing, a mirror, a monitor, a processor, and an indicating module. The mirror and the hollow casing define a chamber therein, and the mirror includes a transparent glass and a reflection film formed on the transparent glass, wherein the reflection film is a narrow band pass film. The monitor is configured to automatically monitor road conditions and generate corresponding road condition signals. The processor is configured to analyze the road condition signals, and to generate switching signals. The indicating module is received in the chamber and facing the mirror, wherein the indicating module is configured to be activated by the switching signal and emit corresponding light rays, the light rays of the indicating module passing through the reflection film and forming an indication sign on the outside of the road traffic mirror.

Abstract: A transit center apparatus is provided having one or more modules attachable to a transit stop pole to provide one or more of the following conveniences to a transit stop patron: information in an optionally illuminated modular display apparatus, overhead illumination, video camera surveillance, and wireless communication. These conveniences are preferably provided through an overhead assembly and a rugged information display case. The overhead assembly houses one or more of the group consisting of solar cells, a rechargeable battery pack, overhead lights, a cell phone antenna, camera, and related circuitry. The information display case provides backlighting and houses a switch assembly. The display case is preferably constructed from extruded, interlocking aluminum frame members and is easily installable on existing support poles.

Abstract: A mechanically operated, gravity-assisted display device has the capability of being remotely controlled by an unskilled operator to display current numeric pricing indicia for a product or other alpha-numeric indicia for any required purpose. The device is ideally suited for displaying the unit price of gasoline on an elevated sign at a filling station. Multiple gravity-biased sliding panels which are arrayed to form variable indicia are operated remotely by flexible suspension elements equipped individually with fixed enlargements. Interchangeable coded remote operating cards for groups of the flexible suspension elements have passages through which predetermined enlargements may pass while other enlargements are blocked. Movement of the block enlargements with the flexible suspension elements to which they are attached under influence of the coded cards establishes the required change of displayed indicia.
