Computing device

1. A computing device comprising:

a processor;

memory accessible by the processor;

a housing that comprises a surface; and

a deployable attachment mechanism for releasable attachment of an object to the surface, wherein the deployable attachment mechanism comprises a multilayer component that comprises a magnetic layer and a fiber layer, and wherein the fiber layer comprises one or more of a contact fastener layer and a shear resistance layer.

2. The computing device of claim 1 , wherein the attachment mechanism comprises an electromagnet.

3. The computing device of claim 1 , wherein fibers of the fiber layer comprise contact fastener fibers that comprise hooks and loops.

4. The computing device of claim 1 , wherein fibers of the fiber layer comprise polymeric shear resistance fibers that increase a coefficient of friction of the surface.

5. The computing device 1 , comprising a Hall effect sensor operatively coupled to the deployable attachment mechanism.

6. The computing device of claim 5 , wherein a signal generated by the Hall effect sensor controls delivery of energy to an electromagnet of the deployable attachment mechanism.

7. The computing device of claim 6 , wherein the delivery of energy to the electromagnet comprises a current flow direction that depends on the signal.

8. The computing device of claim 1 , comprising a metal detector operatively coupled to the deployable attachment mechanism.

9. The computing device of claim 8 , wherein a signal generated by the metal detector controls delivery of energy to an electromagnet of the deployable attachment mechanism.

10. The computing device of claim 9 , wherein the metal detector comprises the electromagnet.

11. The computing device of claim 1 , wherein the deployable attachment mechanism comprises an array of electromagnets.

12. The computing device of claim 11 , comprising a sensor array operatively coupled to the array of electromagnets.

13. The computing device of claim 1 , comprising a gravitational direction sensor operatively coupled to the deployable attachment mechanism, wherein a signal generated by the gravitational direction sensor controls energy supplied to at least one electromagnet of the deployable attachment mechanism.

14. The computing device of claim 1 , wherein the housing comprises a bay and wherein the deployable attachment mechanism is storable in the bay.

15. A method comprising:

actuating a sensor responsive to detecting a parallel configuration of two housings of a computing device operatively coupled via a hinge assembly, wherein the sensor provides for detecting presence of an object in proximity to a surface of one of the two housings;

detecting presence of the object in proximity to the surface; and

responsive to the detecting, energizing at least one electromagnet to attach the object to the surface.
