1. An apparatus for seeing and for warning traffic crossing at an intersection comprising:
- a partially transparent dome mirror having an outside surface for reflecting incident light and an inside surface for receiving light from inside the dome and passing the light through the mirror;
a light producing system for illuminating the inner surface and transmitting light through the mirror so that the light is visible when viewing the outside surface, the light producing system capable of displaying messages through the mirror for viewing from outside the mirror;
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
the sensing system being in communication with the light producing system, such that the light producing system provides messages visible when viewing the outside surface, the messages provided by said light producing system indicating the direction of approaching traffic and object travel and further indicating information regarding approaching traffic and objects.

Abstract
A partially transparent dome mirror is used to display messages generated from within the dome by a light generating system. The mirror is incorporated in an apparatus for seeing and warning traffic crossing at an intersection in a commercial, industrial or other space to improve worker safety and to avoid costly damage due to collisions at the intersection. The unitary apparatus does not require sensors or other wiring external to the mirror and its supporting frame. The mirror system can also be used in commercial and retail applications for surveillance and advertising.

2. An apparatus for seeing and for warning traffic crossing at an intersection comprising:
-
a partially transparent mirror having a first side for reflecting incident light and a second side for receiving and passing light through the mirror; a light producing system for illuminating the second side, passing light through the mirror so that the light is visible when viewing the first side, the light producing system capable of displaying messages through the mirror; 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, the sensing system able to distinguish at least two of; substantially metallic traffic; substantially non-metallic traffic; size of approaching traffic; and traffic approaching the mirror from traffic departing the mirror; in at least one direction for traffic crossing the intersection; and the sensing system comprising a logic system to determine warning messages and being in communication with the light producing system causing the light producing system to display the warning messages to traffic crossing the intersection in other directions, the warning messages visible when viewing the first side of the mirror, the warning messages provided by said light producing system indicating the direction of approaching traffic and object travel and further indicating information regarding approaching traffic and objects. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. An apparatus for surveillance and advertising in commercial environments comprising:
-
a partially transparent dome mirror having a first side for reflecting incident light from outside the dome and a second side for receiving and passing light from inside the dome through the mirror; a light producing system for illuminating the second side from inside the dome mirror and passing light through the mirror so that the light is visible when viewing the first side, the light producing system capable of displaying images through the mirror for viewing from outside the mirror; and a sensing system for identifying the approach of a customer toward the mirror, said sensing system having a microwave sensor to identify the nature of approaching objects and customer traffic, said apparatus differentiating between metal and non-metal objects and customer traffic and further differentiating between approaching and departing objects and customer traffic, the sensing system being in communication with the light producing system causing the light producing system to provide images visible from outside the mirror, the apparatus capable of sensing objects and customer traffic approaching the mirror and displaying a message through the mirror that can be used for advertising purposes and for alerting purposes while displaying a reflection image visible in the first side of the mirror, the messages provided by said light producing system indicating the direction of approaching object and customer traffic travel and further indicating information regarding approaching objects and customer traffic.
