Patent ID: 7016712

Claim:
A mobile station, comprising: a first enclosure enclosing a first set of mobile-station components and having at least one first return point and a substantially curved rotating first contact surface; a second enclosure enclosing a second set of mobile-station components and having at least one second return point corresponding to said at least one first return point, and having a substantially curved rotating second contact surface configured for engaging said first surface substantially without slippage, wherein the first contact surface comprises a surface having sufficient friction such that when brought into contact with the second contact surface, sliding of the two surfaces with respect to the other is substantially precluded; a conductor electrically connected to the first set of mobile station components and to the second set of mobile-station components; an elastomeric retainer connected between said at least one first return point and said at least one second return point for urging said first surface to said second surface substantially without slippage and for substantially simultaneously facilitating rotation of said first surface about said second surface for positioning said first enclosure with respect to said second enclosure in at least three configurations including at least one of a closed position, a partially open position, and an open position, and wherein said first and second return points are positioned on said respective first enclosure and second enclosure such that space between said first and second return points is less when said first and second enclosures are configured in one of said open position or said closed position than in said partially open position; and wherein the first set of components and the second set of components cooperate with each other to form an operational mobile station.
