Abstract

A beacon device includes a control circuitry, a window, and a plurality of sets of illumination sources. The window includes a prismatic structure forming a ring from a planar perspective. The prismatic structure defines an inside surface and an outside surface from the planar perspective. The plurality of sets of illumination sources are coupled to the control circuitry. Each set of illumination sources includes a first illumination source disposed proximal to the inside surface of the prismatic structure and includes a second illumination source disposed proximal to the outside surface of the prismatic structure. The control circuitry is to illuminate a first set of the plurality of sets of illumination sources to transmit a signal in a first direction.
