Abstract

A charger docking station (102) is used to charge a battery (122) of a portable information device (104), and provide enhanced input (110) and enhanced output (112) ability. The enhanced input allows a user to more easily input information into the portable information device, while the enhanced output allows the user to view more information than may be displayed by a display (126) of the portable information device. When the charger docking station is connected to a power source (116) a power supply (114) provides power to the enhanced input and display elements, but when the power source is disconnected from the power supply, the enhanced input and display elements are powered from the battery of the portable information device, or from an external auxiliary battery (106), or both.

Claims

1. A docking station for a portable information device, comprising:

connector means for hosting the portable information device;

input means for accepting a user input;

display means for displaying information to a user; and

a power supply for providing power to the input means, display means, and a charging means disposed in the portable information device when the power supply is connected to a power source;

wherein the battery of the portable information device powers at least one of the input means and display means when the power supply is not connected to the power source.

2. A docking station as defined in claim 1, wherein the input means comprises a virtual projection keypad.

3. A docking station as defined in claim 1, wherein the display means comprises a projection display.

4. A docking station as defined in claim 1, further comprising an auxiliary battery pocket for accepting a battery for use with the portable information device, the charging means coupled to the auxiliary battery pocket for charging the auxiliary battery, and wherein the auxiliary battery powers at least one of the input means and display means when the power supply is not connected to the power source.

5. A portable information device docking system, comprising:

a portable information device having a keypad, a display, a battery, and connector;

a docking station for hosting the portable information device and having a virtual keypad subsystem, a virtual display subsystem, and a power supply for supplying power to the portable information device, virtual keypad subsystem, and virtual display subsystem, and wherein the virtual keypad subsystem provides a virtual keypad having enhanced functionality relative to the keypad of the portable information device, and wherein the virtual display subsystem provides a virtual display having enhanced functionality over the display of the portable information device;

wherein the virtual keypad subsystem and virtual display subsystem are powered from the power supply when the power supply is connected to a power source; and

wherein at least one of the virtual keypad subsystem and virtual display subsystem are powered by the battery of the portable information device when the power supply of the docking station is not connected to the power source.

6. A portable information device docking system as defined in claim 5, wherein the virtual keypad subsystem is a projection keypad subsystem for projecting the image of a keypad on a surface adjacent the docking station, and for detecting key selection by a user of the docking station.

7. A portable information device docking system as defined in claim 5, wherein the virtual display subsystem is a projection display subsystem.

8. A portable information device docking system as defined in claim 5, wherein the docking station further comprises:

an auxiliary battery pocket for hosting an auxiliary battery to be used with the portable information device; and

a charger for charging the auxiliary battery;

wherein the auxiliary battery powers at least one of the virtual keypad subsystem and virtual display subsystem when the power supply is not connected to the power source.

9. A charger docking station for a mobile communication device, the mobile communication device having a phone keypad, a phone display, and a battery, the charger docking station comprising:

a first pocket for hosting the mobile communication device and connecting to the mobile communication device for communicating signals and power between the charger docking station and the mobile communication device;

an enhanced input subsystem for providing input to the mobile communication device;

an enhanced display subsystem for providing a visual display of information on the mobile communication device;

a power supply for providing power to the mobile communication device, enhanced keypad subsystem, and enhanced display subsystem when the power supply is connected to a power source;

wherein the battery of the mobile communication device is charged when the power supply is connected to the power source; and

wherein the battery of the mobile communication device provides power to at least one of the enhanced keypad subsystem and enhanced display subsystem when the power supply is not connected to a power source.

10. A charger docking station as defined in claim 9, wherein the enhanced input subsystem comprises a QWERTY keypad.

11. A charger docking station as defined in claim 10, wherein the QWERTY keypad is provided by a projection system projecting an image of a QWERTY keypad on a surface in proximity to the charger docking station and detecting when spaces corresponding to individual keys of the QWERTY keypad are contacted by a user.

12. A charger docking station as defined in claim 10, wherein the QWERTY keypad is provided by a roll-up keypad.

13. A charger docking station as defined in claim 9, wherein the enhanced input subsystem comprises a navigation device..

14. A charger docking station as defined in claim 13, wherein the navigation device comprises a roller for scrolling information displayed by the enhanced display subsystem.

15. A charger docking station as defined in claim 13, wherein the navigation device comprises a multi-axis button.

16. A charger docking station as defined in claim 9, wherein the enhanced display subsystem comprises a projection system for projecting a display on a surface in proximity to the charger docking station.

17. A charger docking station as defined in claim 9, further comprising:

a second pocket for hosting an auxiliary battery for use with the mobile communication device; and

a charging circuit for charging the auxiliary battery when the auxiliary battery is present in the second pocket and when the power supply is connected to the power source, the power supply providing power to the charging circuit.

18. A charger docking station as defined in claim 17, wherein the auxiliary battery provides power to at least one of the enhanced input subsystem and enhanced display subsystem when the power supply is not connected to a power source.
