Abstract

A cabinet maintains one or more food products at a predetermined temperature. In one general aspect, the cabinet includes at least one modular shelving unit capable of interconnecting with one or more additional modular shelving units. Each modular shelving unit includes a passageway for storing food products, a display for presenting information regarding food products stored in the passageway, and a control system for individually controlling the operations of the modular shelving unit.

Claims

1. A cabinet for maintaining one or more food products at a predetermined temperature, the cabinet comprising:

at least one modular shelving unit capable of interconnecting with one or more additional modular shelving units, each modular shelving unit including;

a passageway for storing food products, the passageway having a width dimension capable of storing at least two food products;

a display for presenting information regarding food products stored in the passageway; and

a control system for individually controlling the operations of the modular shelving unit including controlling the temperature of the passageway and controlling the presentation of information by the display.

2. The cabinet of claim 1, wherein the modular shelving unit comprises at least one bezel assembly, the bezel assembly including a display screen and a slot forming an opening of the passageway.

3. The cabinet of claim 2, wherein the modular shelving unit comprises at least two bezel assemblies.

4. The cabinet of claim 2, wherein the display screen comprises a vacuum florescent display.

5. The cabinet of claim 2, wherein the display screen includes touch screen functionality.

6. The cabinet of claim 2, wherein at least part of the control system is included within the bezel assembly.

7. The cabinet of claim 1, wherein the modular shelving unit comprises a heater assembly for maintaining food products at a particular temperature, the heater assembly including frame components supporting a top heater plate and bottom heater plate.

8. The cabinet of claim 7, wherein the frame components include interconnection wiring capable of communicating with interconnection wiring of one or more additional modular shelving units.

9. The cabinet of claim 7, wherein the heater assembly comprises a temperature sensor for providing temperature detection signals to the control system.

10. The cabinet of claim 7, wherein at least part of the control system is included in the heater assembly.

11. The cabinet of claim 1, wherein the modular shelving unit comprises a position sensor for detecting location of food products within the passageway.

12. The cabinet of claim 11, wherein the position sensor provides position indication signals to the control system.

13. The cabinet of claim 1, wherein the control system comprises switching circuitry for controlling the temperature of the passageway.

14. The cabinet of claim 1, wherein the control system comprises a network interface for sending and receiving communication data.

15. The cabinet of claim 14, wherein the network interface comprises at least one of a modem, communication card, transmitter, and network adapter.

16. The cabinet of claim 14, wherein the communication data comprises at least one of infrared communication data and radio frequency communication data.

17. The cabinet of claim 14, wherein the communication data is capable of being rendered by a wireless communications device as a substantially real-time representation of an operating condition of the cabinet.

18. The cabinet of claim 1, further comprising at least two modular units.

19. A cabinet for maintaining one or more food products at a predetermined temperature, the cabinet comprising:

at least one modular shelving unit capable of interconnecting with one or more additional modular shelving units, each modular shelving unit including;

holding means for storing food products, the holding means capable of storing at least two food products;

display means for presenting information regarding food products stored by the holding means; and

control means for individually controlling the operations of the modular shelving unit including controlling the temperature of the holding means and controlling the presentation of information by the display means.

20. A modular shelving unit, comprising:

a passageway for storing food products, the passageway having a width dimension capable of storing at least two food products;

a display for presenting information regarding food products stored in the passageway; and

a control system for individually controlling the operations of the modular shelving unit including controlling the temperature of the passageway and controlling the presentation of information by the display,

wherein the modular shelving unit is capable of interconnecting with one or more additional modular shelving units to form a cabinet for maintaining one or more food products at a predetermined temperature.
