Methods and apparatus for generating force and torque
First Claim
1. An apparatus, comprising:
- a cam having at least a first guiding surface;
a cam following assembly including a first following surface for engaging the first guiding surface of the cam at least at a first contact point, and a means for urging the first following surface against the first guiding surface of the cam;
the first following surface defining a contact angle with the first guiding surface of the cam;
the first guiding surface of the cam being shaped such that the contact angle of the first follower changes substantially continually as the cam following assembly moves along a longitudinal axis of the cam;
wherein the means for urging the first following surface against the first guiding surface of the cam comprises a leaf spring; and
wherein said spring is positioned between said cam and said cam following assembly.

Abstract
A system for providing support and position control of a monitor. In one embodiment, a method of supporting a monitor includes converting an ascending energy storage member force curve into a substantially constant supporting force against the monitor. In one aspect, a method, of supporting a monitor includes providing an energy storage member and a cam which are cooperatively positioned so as to move relative to each other along the path of motion. As the energy storage member moves along the path relative to the cam, the cam displaces the energy storage member and thereby changes a force applied by the energy storage member on the cam, and wherein the cam converts the force applied by the energy storage member into a supporting force on the monitor.
