Abstract
A device is described herein that incorporates correlated magnets which enable a cover to be easily and effectively attached to and removed from a compartment. Some examples of such a device include a remote control unit, a calculator, a clock-radio, a mobile phone, a laptop computer, a personal digital assistant (PDA), a camera, a television, a portable media player, and a handheld electronic game unit.
Claims20
A device comprising:
- a cover including a first field emission structure;
- and
- a compartment including a second field emission structure, where the cover is attached to the compartment to enclose a space within the compartment when the first and second field emission structures are located next to one another and have a certain alignment with respect to one another, where each of the first and second field emission structures include field emission sources having positions and polarities relating to a desired spatial force function that corresponds to a relative alignment of the first and second field emission structures within a field domain.
A method for enabling a cover to be attached to and removed from a compartment within a device, said method comprising the steps of:
- attaching a first field emission structure to the cover;
- attaching a second field emission structure to the compartment;
- and
- aligning the first and second field emission structures so the cover attaches to the compartment and encloses a space within the compartment when the first and second field emission structures are located next to one another and have a certain alignment with respect to one another, where each of the first and second field emission structures include field emission sources having positions and polarities relating to a desired spatial force function that corresponds to a relative alignment of the first and second field emission structures within a field domain.
