Patent ID: 7378982

Claim:
A device for displaying multiple pre-programmed messages, comprising: a first housing adapted to be mounted in a first location, a first electronic display mounted in the first housing, a first microprocessor associated with the first housing and being operably connected to the first electronic display for communicating display instructions to the first electronic display to generate a viewable message based on a selected message signal; a second housing adapted to be mounted in a second location, a second electronic display mounted in said second housing, a second microprocessor associated with the second housing and having a plurality of programmed message signals, means for conducting electric signals between the first microprocessor and the second microprocessor such that the second microprocessor is operably connected to the first microprocessor for communicating the selected message signal to the first microprocessor, the second microprocessor further being operably connected to the second electronic display for communicating display instructions to the second electronic display to generate a viewable message based on the selected message signal; message selection means associated with the second housing and being operably connected to the second microprocessor for enabling a user to select from the plurality of programmed message signals, the second microprocessor communicating the selected message signal to the second electronic display to generate the viewable message and further communicating the selected message signal to the first microprocessor; and a source of electricity associated with one of said first or second housings for supplying electric power to the device; wherein the message selection means comprises a plurality of buttons, each button being associated with a respective programmed message signal corresponding to a message to be displayed.
