Abstract

A fuel dispenser comprises a housing, a dispensing hose, a pump operatively connected to the dispensing hose and a source of fuel. A computer is operatively connected to the pump, a power supply is operatively connected to the computer and an auxiliary power supply is operatively connected to the computer. The auxiliary power supply is configured to provide power for a predetermined amount of time if the power supply should fail. A first display has a rear polarizing layer and a front polarizing layer. The first display is mounted in the housing so that the front polarizing layer is viewable by a user. A second display has only a front polarizing layer positioned adjacent to the first display front polarizing layer so that the first display projects an image through the second display. The first display and the second display are operatively connected to the power supply and the computer. The second display is operatively connected to the auxiliary power supply.

Claims

1. A fuel dispenser comprising:

a. a housing;

b. a dispensing hose;

c. a pump operatively connected to said dispensing hose and a source of fuel;

d. a computer operatively connected to said pump;

e. a power supply operatively connected to said computer;

f. an auxiliary power supply operatively connected to said computer, said auxiliary power supply configured to provide power for a predetermined amount of time if said power supply should fail;

g. a first display having a rear polarizing layer and a front polarizing layer, said first display mounted in said housing so that said front polarizing layer is viewable by a user; and

h. a second display having only a front polarizing layer positioned adjacent to said first display front polarizing layer so that said first display projects an image through said second display,

wherein

said first display and said second display are operatively connected to said power supply and said computer, and

said second display is operatively connected to said auxiliary power supply.

2. The fuel dispenser of claim 1, wherein said auxiliary power supply is a battery.

3. The fuel dispenser of claim 1, wherein said auxiliary power supply is a capacitor.

4. The fuel dispenser of claim 1, wherein said first and said second displays are independently connected to said power supply and said computer.

5. The fuel dispenser of claim 1, wherein said first and said second displays are LCD displays.

6. The fuel dispenser of claim 1, wherein said second display is lit from polarized light from said first display.

7. The fuel dispenser of claim 1, further comprising touch screen electronics.

8. A fuel dispenser comprising:

a. a dispenser housing;

b. a dispenser system adapted to be connected to a fuel source;

c. a computer operatively connected to said dispenser system;

d. a power supply; and

e. a graphic display system mounted in said dispenser housing, said graphic display system comprising,

i. a first display having a front surface and a rear surface, said first display being operatively connected to said computer and said power supply;

ii. a second display having a front surface and a rear surface, wherein said second display is positioned adjacent said first display so that said second display rear surface is adjacent said first display front surface,

wherein said first and said second displays are independently connected to said power supply and said computer.

9. The fuel dispenser of claim 8, wherein said power supply comprises a main power source and an auxiliary power source.

10. The fuel dispenser of claim 9, wherein said auxiliary power source is a battery.

11. The fuel dispenser of claim 9, wherein said auxiliary power supply is a capacitor.

12. The fuel dispenser of claim 8, wherein said first and said second displays are LCD displays.

13. The fuel dispenser of claim 8, wherein said first display is side lit.

14. The fuel dispenser of claim 8, further comprising touch screen electronics.

15. The fuel dispenser of claim 8, said display system further comprising:

a. a first polarizing layer disposed on said first display rear surface and a second polarizing layer disposed on said first display front surface, and

b. a third polarizing layer disposed on said second display front surface.

16. A transaction terminal comprising:

a. a terminal housing;

b. a computer;

c. a power supply; and

d. a graphic display system mounted in said terminal housing, said graphic display system comprising,

i. a first display having a front surface and a rear surface, said first display being operatively connected to said computer and said power supply;

ii. a second display having a front surface and a rear surface, wherein said second display is positioned adjacent said first display so that said second display rear surface is adjacent said first display front surface,

iii. a first polarizing layer disposed on said first display rear surface and a second polarizing layer disposed on said first display front surface, and

iv. a third polarizing layer disposed on said second display front surface,

wherein said second display rear surface does not contain a polarizing layer.

17. The transaction terminal of claim 16, wherein said power supply is a battery.

18. The fuel dispenser of claim 16, wherein said first and said second displays are independently connected to said power supply and said computer.

19. The fuel dispenser of claim 18, wherein said first and said second displays are LCD displays.
