Abstract

A method and system enables users of a system such as a mass transit system to receive status information about the system. The information may relate to one or more stops or vehicles along various routes of the system. The user is provided with a display device, and one or more readers are positioned throughout the system. The display device includes a display screen that displays system status information, a driving circuit, an antenna and an inductive coil. When the display device'"'"'s inductive coil is in the presence of a proximate electromagnetic field and the antenna receives a data signal, the inductive coil delivers power to the driving circuit, and the driving circuit causes the display screen to display updated system status information.

Claims

1. A system for receiving transportation system status information, comprising:

a display device comprising;

a display screen,

a driving circuit,

an antenna, and

an inductive coil;

wherein when the inductive coil is in the presence of a proximate electromagnetic field generated by a card reader and the antenna receives a data signal from the card reader that comprises data that is representative of transportation system status information;

the inductive coil delivers power to the driving circuit, and

the driving circuit causes the display screen to display the data that is representative of transportation system status information.

2. The system of claim 1, wherein an inductive coil of the card reader generates the electromagnetic field.

3. The system of claim 2, wherein:

the display device is a bichromal display device that also comprises a conductive substrate and a bichromal material positioned over the conductive substrate, and

the driving circuit is configured to, in response to the data signal, causes a voltage change in a portion of the conductive substrate, wherein the voltage change causes a corresponding change in an image displayed by the bichromal material to yield the updated data that is representative of transportation system status information.

4. The system of claim 2, wherein the card reader also comprises a transceiver that generates the data signal.

5. The system of claim 2, wherein the card reader is in electronic communication with an external transmitter that generates the data signal.

6. The system of claim 1, wherein the display device further comprises a battery, and the inductive coil also delivers power to the battery when the inductive coil is in the presence of a proximate electromagnetic field.

7. The system of claim 1, further comprising a case, the case comprising:

a first receptacle that is of a size and shape to receive and hold the display device; and

a second receptacle that is of a size and shape to receive and hold the transaction card.

8. The system of claim 1, wherein the display device powers off within a certain period of time after failing to detect the presence of the electromagnetic field generated by the card reader.

9. A method of delivering transportation system status information to a user, comprising:

providing a user with a display device, the device comprising a display screen, a driving circuit, an antenna, and a secondary inductive coil;

receiving, via a card reader, an informational signal indicating that the user is located at a transportation stop;

in response to receiving the informational signal;

selecting data that is representative of transportation system status information;

generating a data signal containing the data that is representative of transportation system status information;

activating a primary inductive coil to generate an electromagnetic field that, when received by the secondary inductive coil will power the driving circuit of the display device and cause the display screen to display the transportation system status information.

10. The method of claim 9, wherein:

the display device also comprises a conductive substrate and a bichromal material positioned over the conductive substrate;

the causing the display screen to display the transportation system status information comprises causing a voltage change in a portion of the conductive substrate, wherein the voltage change causes the bichromal material to display the transportation system status information.

11. The method of claim 9, further comprising providing the user with a transaction card that generates the informational signal.

12. The method of claim 9, wherein selecting the data that is representative of transportation system status information comprises:

receiving, from a scheduling system, system status information for a plurality of vehicles; and

selecting a portion of the system status information for delivery to the user.

13. The method of claim 9, wherein selecting the data that is representative of transportation system status information comprises:

receiving, from a scheduling system, system status information for a plurality of vehicles; and

delivering a common message to all user displays that the card reader detects within a certain period of time.

14. The method of claim 12, wherein selecting the portion of the system status information for delivery to the user comprises:

in response to receiving the informational signal, accessing a database of user-specific information; and

based on the user-specific information, identifying system status information that is relevant to the user.

15. The method of claim 14, wherein selecting the portion of the system status information for delivery to the user also comprises:

determining that the system status information that is relevant to the user has a size that exceeds a viewable size of the display device; and

prioritizing the system status information that is relevant to the user so that only a prioritized portion of the relevant system status information appears as the selected information.

16. The method of claim 14, wherein:

identifying system status information that is relevant to the user comprises;

identifying a home route between the transportation stop and a home location of the user,

identifying a transportation interruption corresponding to the home route,

identifying an alternate route of travel between the transportation stop and the home location; and

the method also includes causing display screen to display information corresponding to the alternate route of travel.

17. A system for delivering information to a user, comprising:

a display device comprising;

a display screen that displays status information,

a driving circuit,

an antenna, and

a secondary inductive coil; and

a card reader having a primary inductive coil and a transmitter;

wherein

the primary inductive coil generates an electromagnetic field, and the transmitter transmits a data signal comprising data that is representative of transportation status information, when the reader detects that the display device is within a detection range; and

in response to the generation of the electromagnetic field;

the secondary inductive coil receives the electromagnetic field and delivers power to the driving circuit,

the antenna receives the data signal, and

in response to the data signal, the driving circuit causes the display screen to display updated status information that comprises the data that is representative of transportation system status information.

18. The system of claim 17, also comprising a transaction card having a memory, a transponder, and an antenna.

19. The system of claim 18, wherein display device further comprises a battery, and the inductive coil also delivers power to the battery when the inductive coil is in the presence of the proximate electromagnetic field.

20. The system of claim 18, wherein:

the display screen comprises a bichromal material positioned over a conductive substrate, and

the driving circuit is configured to, in response to the data signal, cause a voltage change in a portion of the conductive substrate, wherein the voltage change causes a corresponding change in an image displayed by the bichromal material to yield the updated status information.

21. The system of claim 17, wherein the display device powers off within a certain period of time after failing to detect the presence of the electromagnetic field generated by the card reader.
