Abstract

A magnetic attachment mechanism and method is described. The magnetic attachment mechanism can be used to releasably attach at least two objects together in a preferred configuration without fasteners and without external intervention. The magnetic attachment mechanism can be used to releasably attach an accessory device to an electronic device. The accessory device can be used to augment the functionality of usefulness of the electronic device.

Claims

1. An accessory device capable of separable magnetic attachment to a portable electronic device, the accessory device comprising:

a body that is capable of carrying;

(i) an input device capable of detecting a tactile input and responding to the tactile input by providing a control signal,

(ii) a magnetic element capable of magnetically attaching the body, in a pre-determined orientation and alignment, to a housing of the portable electronic device, and

(iii) a communication port, wherein when the body and the housing are magnetically attached to each other, a communication channel, between the communication port and the portable electronic device, is established that is capable of carrying the control signal that causes the portable electronic device to perform an operation that the portable electronic device is only capable of performing in response to the control signal.

2. The accessory device as recited in claim 1 wherein the input device is a keyboard.

3. The accessory device as recited in claim 1 wherein the input device is a touch pad.

4. The accessory device as recited in claim 1, wherein the accessory device further includes a single piece flap attached to the body, wherein the single piece flap carries the input device.

5. The accessory device as recited in claim 1, wherein the portable electronic device includes a charge storage device.

6. The accessory device as recited in claim 5, the body further comprising:

an external power connector capable of receiving external power from an external power supply and passing at least some of the received power to the charge storage device.

7. The accessory device as recited in claim 6, wherein at least some of the received power is wirelessly transmitted between the accessory device and the portable electronic device.

8. The accessory device as recited in claim 1, wherein the communication channel is wireless.

9. The accessory device as recited in claim 1, wherein the portable electronic device is a tablet device.

10. The accessory device as recited in claim 1, wherein the portable electronic device is a portable communication device that includes a cell phone.

11. The accessory device as recited in claim 1, wherein the communication channel is operable only when the body and the housing are magnetically attached to each other.

12. A method operable by a portable electronic device having a housing capable of carrying a magnetic sensor and an electronic component capable of providing a first electronic function, the method comprising:

detecting, by the magnetic sensor, that a body of an accessory device is magnetically attached to the housing, wherein the body carries a tactile sensor capable of sensing a tactile input and providing a control signal in response thereto;

forming, based upon the detecting, a communication channel between the electronic component and the tactile sensor, wherein the communication channel is capable of carrying the control signal from the tactile sensor to the electronic component; and

providing, by the electronic component in accordance with the control signal, a second electronic function (i) that is different than the first electronic function, and (ii) that the electronic component is only capable of providing in response to the control signal.

13. The method as recited in claim 12, wherein the communication channel is wireless.

14. The method as recited in claim 12, wherein the sensor is a magnetic sensor.

15. The method as recited in claim 12, wherein the magnetic sensor is a Hall Effect Sensor.

16. The method as recited in claim 12, wherein the tactile sensor is a keyboard.

17. The method as recited in claim 12, wherein the tactile sensor is a touchpad.

18. A cooperative electronic system, comprising:

a portable electronic device with a housing capable of carrying a display and a first communication port, and an accessory device that includes (i) a single piece flap having a keyboard and (ii) a body portion pivotally coupled to the single piece flap and having a magnetic element capable of forming a separable magnetic attachment to the housing, the body portion further including a second communication port electrically coupled to the keyboard, wherein a communication channel between the first and second communication ports, formed in accordance with the forming of the separable magnetic attachment, is capable of carrying a keyboard control signal provided by the keyboard in response to a tactile event.

19. The cooperative electronic system as recited in claim 18, wherein the keyboard control signal causes the portable electronic device to perform an operation that the portable electronic device is only capable of performing in response to the keyboard control signal.

20. The cooperative electronic system as recited in claim 19, wherein the operation includes displaying textual content by the display, the textual content corresponding to the tactile event.
