Abstract: Methods and tools for positioning cables using magnets during assembly of a consumer electronic product are described. Methods described are well suited in the manufacture of portable electronic devices such as mobile phones, computer tablets and the like. Methods involve attaching magnetic components to cables and to one or more surfaces within the enclosure of the electronic devices. During assembly, the magnetic components on the cables magnetically couple with corresponding magnetic components on the surfaces within the enclosure. In this way, the cables can be secured in certain positions and out of the way during the assembly of the electronic device. In some instances, the cables can remain magnetically secured after assembly and during the operation of the electronic device. In other instances, the magnetic components are decoupled after assembly thereby releasing the cables from their secured positions during operation of the electronic device.

Abstract: A cushion, using magnetic friction as base protection is specifically tested and designed for use in helmets to minimize the risk of concussions. The cushion can be used in a two layer helmet where the magnets are used to repel the impact normally taken straight to the head. The magnets can be placed in between the layers to not only take the impact, but also give that force back towards the source, creating a cushion like no other helmet. With this two-layer system, one can measure that the first layer of magnets takes the hit and uses the second layer to push back off of. This movement that the helmet takes significantly improves protection of the brain as compared to conventional helmets.
