Abstract

Embodiments of the invention relate to an apparatus comprising a housing having a substantially rectangular shape and including a top side, a bottom side, and a slot that passes from the top side to the bottom side of the housing to secure a mobile input device in an upright configuration. The apparatus further includes an energy storage device disposed within the housing to charge the mobile input device. The energy storage device may charge the mobile input device by inductive charging or hardwire (e.g., via a retractable cable). The slot can include a coating or covering to increase a coefficient between the slot and the mobile input device. The slot can be disposed in the long end of the housing and can support the mobile input device in either a portrait or landscape upright configuration, from either the top end or the bottom end.

Claims

1. A charging apparatus comprising:

a housing having a substantially rectangular shape and including;

a top side;

a bottom side; and

a slot that passes through from the top side to the bottom side of the housing such that the slot is accessible from the top side and the bottom side of the housing, the slot operable to receive and secure a mobile input device in an upright configuration; and

an energy storage device disposed within the housing to electrically couple to and charge the mobile input device.

2. The apparatus of claim 1 further comprising an inductive device to inductively transfer energy from the energy storage device to the mobile input device.

3. The apparatus of claim 1 further comprising a cable to couple to and transfer energy from the energy storage device to the mobile input device.

4. The apparatus of claim 3 wherein the cable is retractable.

5. The apparatus of claim 1 wherein the slot includes inner walls having a surface area, wherein the surface area of the inner walls includes a covering to increase a coefficient of friction between the mobile input device and the surface area of the slot when the mobile input device is secured in the slot in the upright configuration.

6. The apparatus of claim 5 wherein the covering includes a rubber or polyurethane (PU) coating.

7. The apparatus of claim 1 wherein the rectangular-shaped housing includes long edges and short edges, and wherein the slot extends along one of the long edges of the housing.

8. The apparatus of claim 1 wherein the slot supports the mobile input device in an upright portrait or landscape orientation.

9. The apparatus of claim 1 wherein the slot supports the mobile input device in both a forward facing or rear facing upright configuration.

10. The apparatus of claim 1 wherein the slot is operable to receive the mobile input device from both the top side or from the bottom side of the housing.

11. The apparatus of claim 1 wherein at least a portion of the slot widens to form a grip-like opening to conform to a human hand.

12. The apparatus of claim 1 further comprising an integrated input or output device disposed in the housing, the input device or output device including at least one of:

a keyboard;

a trackpad;

a speaker;

a joystick;

a display;

a touchpad;

a game pad;

or

a microphone.

13. A portable charging device comprising:

a rectangular housing;

a slot disposed in and passing through the housing, the slot operable to support a mobile input device in an upright configuration; and

an energy storage device disposed in the housing to couple to and charge the mobile input device.

14. The portable charging device of claim 13 wherein the slot is over-molded with a rubber or PU coating to increase a coefficient of friction between the slot and the mobile input device when the mobile input device is placed in the slot.

15. The portable charging device of claim 13 wherein the housing includes a top side and a bottom side, wherein the slot is operable to receive the mobile input device from both the top side or the bottom side of the housing.

16. The portable charging device of claim 13 wherein the slot includes a widened region forming a grip-like opening to conform to a human hand.

17. The portable charging device of claim 13 further comprising an integrated input or output device disposed in the housing, the input device or output device including at least one of:

a keyboard;

a trackpad;

a speaker;

a joystick;

a display;

a touchpad;

a game pad;

or

a microphone.

18. The portable charging device of claim 17 wherein the input or output device is activated when the mobile input device is configured in the slot, and

wherein the input or output device is deactivated when the mobile input device is not configured in the slot.

19. The portable charging device of claim 13 wherein the mobile input device is a tablet computer.

20. The portable charging device of claim 13 wherein the slot supports the mobile input device in both a forward facing or rear facing upright configuration.
