Abstract

This invention includes a charger that may be mounted either in a horizontal configuration, e.g. on a desktop, or in a vertical configuration, e.g. on a wall. The charger has pockets geometrically oriented so as to support batteries in either configuration. Each pocket includes a corresponding display. As changing from a desktop configuration to a wall mount configuration requires the user to rotate the charger by 180 degrees, a switch is provided to rotate the information shown on the display by 180 degrees. The switch is preferably recessed below the surface of the charger so as to prevent nuisance actuation. The resulting orientation of the display is stored in a non-volatile memory to prevent resets when power is removed. By holding the switch down for a predetermined amount of time, a user can send the display into a test mode so as to run diagnostics and verify proper display operation.

Claims

1. A battery charger, comprising:

a. a base member;

b. an inclined plane coupled to the base member at an angle between 30 and 60 degrees with respect to the base member;

c. at least one pocket for receiving a rechargeable battery, the at least one pocket having electrical contacts disposed within the inclined plane;

d. a microprocessor coupled to the electrical contacts;

e. at least one display electrically coupled to the microprocessor; and

f. a switch electrically coupled to the microprocessor;

wherein when the switch is actuated, the microprocessor causes data on the display to change from a first orientation to a second orientation.

2. The charger of claim 1, wherein the switch is disposed within the charger.

3. The charger of claim 2, wherein access to the switch is provided by an opening in the exterior of the charger.

4. The charger of claim 3, wherein a user actuates the switch by inserting a small tool into the opening in the exterior of the charger.

5. The charger of claim 4, wherein the display comprises a liquid crystal display.

6. The charger of claim 1, wherein the second orientation is a 180-degree rotation of the first orientation.

7. The charger of claim 6, wherein a depth of the at least one pocket is at least half of a length of the rechargeable battery.

8. The charger of claim 1, further comprising a non-volatile memory coupled to the microprocessor, wherein when the switch is actuated, the corresponding orientation is stored by the microprocessor in the non-volatile memory.

9. The charger of claim 8, wherein the non-volatile memory is selected from the group consisting of electrically erasable read-only memories and flash memories.

10. A charger capable of being mounted in both a vertical orientation and a horizontal orientation, comprising:

a. a plurality of pockets capable of supporting rechargeable batteries either when the charger is in the vertical orientation or the horizontal orientation;

b. a plurality of displays electrically coupled to the plurality of pockets, respectively; and

c. a plurality of switches coupled to the plurality of displays, respectively;

wherein when a user actuates any one of the plurality of switches, information shown on the display rotates 180 degrees.

11. The charger of claim 10, wherein the plurality of switches are disposed within the charger.

12. The charger of claim 11, wherein access to the plurality of switches is provided by a plurality of openings disposed on the exterior of the charger.

13. The charger of claim 12, wherein a user actuates one of the plurality of switches by inserting a small tool into one of the plurality of openings on the exterior of the charger.

14. The charger of claim 13, wherein a depth of the plurality of pockets is at least half of a length of the rechargeable batteries.

15. The charger of claim 14, further comprising a plurality of microprocessors coupled to the plurality of pockets, respectively, and a plurality of non-volatile memories coupled to the plurality of microprocessors, wherein when one of the plurality of switches is actuated, the corresponding display rotation is stored by the corresponding microprocessor in the corresponding non-volatile memory.

16. The charger of claim 15, wherein when one of the plurality of switches is actuated for a predetermined amount of time, the corresponding microprocessor enters a test mode.
