Abstract:
For an elevator system disposed in a structure having a plurality of floors and a first source of electrical power for the structure, the elevator system having a second source of electrical power for the elevator system which may or may not be connected to the first source of electrical power, the elevator system having at least one hoistway, each hoistway having an elevator car moving vertically therein which is driven by the second source of electrical power to provide service to the floors of the structure, the elevator system having an elevator dispatch controller having an electromagnetic wireless communications system which is adapted to transmit information to a transceiver at a floor, an elevator fixture for the elevator system at an associated floor, which comprises:an electrohoretic display system having a display layer for communicating at least one visual signal; a transceiver module at the floor which includes a transceiver and which is linked to the fixture for communicating information to the electrophoretic display system; a third source of electrical power for the electrophoretic display system; and, a continuous electrical conductor which extends from the third source of electrical power to the electrophoretic display system, the third source of electrical power not being connected by a continuous electrical conductor to the first source of power which extends through the structure and not being connected by a continuous electrical conductor to the second source of electrical power which extends through the hoistway for the elevator system; wherein the electrophoretic display system, the transceiver module and the third source of electrical power of the fixture are each disposed on the same floor and wherein the transceiver module is in electrical communication with the electrophoretic display system.
