Patent Images
1. A plurality of reusable identification badges for identifying persons or objects, the badges comprising:
- a display panel on a housing of each badge to display a configuration of nonalphanumeric geometrical shapes for the visual identification of said person or object;
a memory within each badge that stores a plurality of programmable configurations that form the nonalphanumeric geometrical shapes displayed on each display panel; and
a control circuit within each badge that alters the programmable configurations displayed on that badge, wherein each of the plurality of badges is altered at a predetermined time interval such that each badge is synchronized with every other badge so that each badge displays the same configuration at any particular time.

18. A method of using a time-varying identification badge system comprising the steps of:
-
selecting an ordered plurality of configurations to be displayed as nonalphanumeric geometrical shapes on a display panel located on each of a plurality of badges; programming a memory in each badge to retain and alter the same configurations on each badge at predetermined time intervals according to the selected order, such that each badge is synchronized with every other badge in the system; attaching one of the badges to a person or object being identified; displaying the configurations on the attached badge such that each configuration can be visually identified; and visually comparing the displayed configuration on the attached badge with a configuration on an observable second badge of the plurality of badges to identify a person or object wearing the second badge. - View Dependent Claims (19, 20, 21, 22, 23)

24. An identification system comprising:
-
a plurality of identification badges each having a display panel, wherein each display panel displays a configuration of nonalphanumeric geometrical shapes for the visual identification of a person or an object; a display memory within each badge to store a plurality of programmable configurations to be displayed on each display panel such that the displayed configuration is the same on each badge; a second memory connected to said display memory within each badge for storing a programmed time interval; and a control circuit connected to said display and second memories within each badge, each control circuit having a clock such that the displayed configuration on each badge is altered to another of the configurations stored within the display memory of each badge at substantially the same programmed time interval. - View Dependent Claims (25, 26, 27)
