Patent ID: 7583500

Claim:
An electronic device, comprising: a first body; a second body hingedly connected to the first body; a first magnetic component positioned on the first body and comprising— first permanent magnets arranged adjacent one another in a first line, separated by a first distance from one another, and arranged with alternating first and second polarities, and a first ferromagnetic element positioned at a first end of the first line; and a second magnetic component positioned on the second body and being movable between an open state and a closed state, the second component comprising— second permanent magnets arranged adjacent one another in a second line parallel to the first line, separated by a second distance from one another, and arranged with alternating first and second polarities, and a second ferromagnetic element positioned at a second end of the second line, the second end being opposite of the first end, wherein to maintain the first body substantially closed against the second body, the first and second magnetic components are magnetically attractable to one another when the second magnetic component has the closed state, and wherein to move the first body at least partially open from the second body, the first and second components are magnetically repellable from one another when the second magnetic component has the open state.
