Patent ID: 7355843

Claim:
A computer with a touch sensitive or pen sensitive display, wherein the position of the fully opened display is such that the maximum torque typically applied to the top most pen or touch sensitive part of the display, in relation to a rotational axis about which the computer would rotate if it were to tip backwards, is less than that needed to cause the computer to tip backwards about that rotational axis, but would be sufficient to cause such tipping if the display were hinged in a conventional clam shell arrangement at the rear of the computer; the torque is less than that needed to cause tipping because the length of the moment arm, i.e. the length of the distance from the point of application of the turning force to the rotational axis, is less than the length of the moment arm would be if the display were hinged at a fixed point at the rear of the computer in a conventional clam shell arrangement; and the length of the moment arm is reduced by extending the rear of the computer.
