Abstract

Currently pre-printed signs are used for many functions and are not always appropriate or attractive. The present invention provides an electronic display with multiple pre-programmed messages. A particularly useful application is for preprogrammed messages to be displayed by a hotel guest on the corridor side of the hotel room door.

Claims

1. A device for displaying multiple pre-programmed messages, comprising:

a) a first housing adapted to be mounted in a first location;

b) a first electronic display screen mounted in said first housing;

c) a second housing adapted to be mounted in a second location;

d) a second electronic display screen mounted in said second housing;

e) a first processing device for providing display information to said display screen in said first housing;

f) a second processing device for providing display information to said display screen in said second housing;

e) a power source in one of said first or second housings for supplying electric power to said display screens and said first and second processing devices;

f) means for selecting a message to be displayed on said first and second displays; and

g) means for conducting electric signals between said first and second processing devices.

2. The device of claim 1 wherein said first and second display screens each comprises an LCD display.

3. The device of claim 1 wherein said first and second housings are adapted to be secured to opposite sides of a door.

4. The device of claim 3 further comprising switching means for selectively displaying a message on said first and second display screens.

5. The device of claim 3 wherein said means for conducting electric signals between said first and second processing devices extends through said door.

6. The device of claim 3 wherein said first and second housings are removably secured to said opposite sides of said door by tamper-resistant screws.

7. The device of claim 3 wherein said processor means has a preprogrammed selection of messages adapted to be displayed electronically simultaneously on said first and second display screens.

8. The device of claim 1 wherein said power source comprises a battery mounted on one of said housings.

9. The device of claim 1 wherein one of said housings is provided with a motion sensor.

10. The device of claim 1 wherein one of said housings is provided with an audio speaker.

11. The device of claim 1 wherein said first and second processing devices are adapted to communicate wirelessly by audio frequency.

12. The device of claim 1 wherein said first and second processing devices are adapted to communicate wirelessly by radio frequency.

13. The device of claim 1 wherein said first and second display screens each comprises an LED display.

14. The device of claim 1 wherein said first and second housings are secured to said door by tamper-resistant screws.

15. The device of claim 1 wherein said first and second housings are removably secured by suction cups.
