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. A cover suitable for protecting a tablet device having a housing that includes an opening in accordance with a full front side of the tablet device and an optically clear protective layer carried by the housing within the opening that (i) overlays a display configured for presenting visual content and (ii) overlays a tablet device attachment element at a first location, the cover comprising:

a single piece flap pivotally attachable to the tablet device and having a size and a shape in accordance with the optically clear protective layer and comprising;

a flap attachment element carried at a second location within the single piece flap, wherein when a part of the single piece flap corresponding to the second location is brought into proximal contact with the optically clear protective layer corresponding to the first location, the flap attachment element and the tablet device attachment element form a bond through the optically clear protective layer that secures the flap directly to the outer protective layer at the first location.

2. The cover as recited in claim 1, wherein a positioning of the single piece flap with respect to the outer protective layer is usable to control an operation of the tablet device.

3. The cover as recited in claim 2, wherein the single piece flap being secured to the optically clear protective layer defines a closed configuration of the cover with respect to the tablet device.

4. The cover as recited in claim 3, wherein when the cover is in the closed configuration, the tablet device operates in accordance with the closed configuration, otherwise, the tablet device operates in accordance with an amount of the display that is exposed.

5. The cover as recited in claim 4, wherein the tablet device operates in accordance with the closed configuration by powering off the display.

6. The cover as recited in claim 5, wherein the tablet device operates in accordance with the amount of the display that is exposed by the display presenting video content only at the exposed amount of the display.

7. The cover as recited in claim 1, wherein the single piece flap is operable as a support structure that facilitates operation of the tablet device in a pre-determined operating mode.

8. The cover as recited in claim 7, wherein the support structure comprises a triangle and supports the tablet device at an acute angle with respect to a horizontal support surface.

9. The cover as recited in claim 1, wherein the tablet device attachment element comprises a first magnetic element and wherein the flap attachment element comprises a second magnetic element capable of forming the magnetic circuit through the optically clear protective layer with the first magnetic element.

10. The cover as recited in claim 1, wherein the tablet device further comprises a sensor usable to detect the positioning of the single piece flap with respect to the outer protective layer.

11. The cover as recited in claim 1, wherein the cover further comprises an electronic circuit capable of communication with the tablet device.

12. The cover as recited in claim 11, wherein the electronic circuit comprises an input device capable of detecting an input event at the single piece flap.

13. The cover as recited in claim 12, wherein the input device is a keyboard.

14. An electronic device operable by a protective cover comprising a single piece flap having a size and a shape in accordance with a full front side of tablet device and comprising a first portion that is movable away from the outer protective layer and having a first magnetic element, a second portion opposite the first portion that is pivotally attachable to the electronic device and a third portion disposed between the first and second portions, the electronic device comprising:

a processor;

a display configured for presenting visual content coupled to the processor and comprising an outer protective layer overlaying the display and having a size and a shape in accordance with a full front side of tablet device; and

a second magnetic element, wherein the first and second magnetic elements form a magnetic circuit through the outer protective layer that magnetically attaches the single piece flap to the outer protective layer.

15. The cover as recited in claim 14, wherein the electronic device is operable in accordance with a position of the first portion with respect to the outer protective layer.

16. The cover as recited in claim 15, wherein the position of the first portion with respect to the outer protective layer affects the detection of the first magnetic element through the outer protective layer by a sensor carried by the electronic device.

17. The cover as recited in claim 16, wherein in a closed position in which the first portion is substantially in contact with the outer protective layer, the sensor is deemed to detect the first magnetic element, otherwise, the sensor is deemed to not detect the first magnetic element.
