Mirror alert with projected message

摘要

An apparatus includes a mirror dome and a light producing system for producing and transmitting light through the mirror dome to an external surface to produce a message viewable on the external surface. A sensing system identifies traffic and is in communication with the light producing system to cause the light producing system to produce and project a message viewable on the external surface when the sensing system detects approaching objects or traffic.

主权项

1. An apparatus for seeing and for warning traffic crossing at an intersection comprising:
a partially transparent mirror dome having an outside surface for reflecting incident light and an inside surface for receiving light from inside said mirror dome and passing the light through said mirror dome; a light producing system for producing and transmitting light through said mirror dome wherein the light is projected through said mirror dome to an external surface separated from said mirror dome, said light producing system producing a message with the light projected through said mirror dome that is viewable on the external surface; a sensing system for identifying traffic crossing at the intersection, said sensing system having a microwave sensor to identify the nature of approaching objects and traffic, said apparatus differentiating between metal and non-metal objects and traffic and further differentiating between approaching and departing objects and traffic; and said sensing system being in communication with said light producing system to cause said light producing system to produce and project a message viewable on the external surface separated from said mirror dome when said sensing system detects approaching objects or traffic, the message provided and projected by said light producing system indicating the direction of approaching traffic and object travel.
