A mechanical isotropic harmonic oscillator including a frame, a mass configured to oscillate, and three flexure rods, each flexure rod connecting the mass to the frame.

General 2 degree of freedom isotropic harmonic oscillator and associated time base without escapement or with simplified escapement

A mechanical isotropic harmonic oscillator including a two rotational degrees of freedom linkage supporting an orbiting mass with respect to a fixed base with at least one spring element having isotropic and linear restoring force properties, such that a high degree of spring stiffness and reduced mass isotropy provides for reduced sensitivity to linear and angular accelerations.

General two degree of freedom isotropic harmonic oscillator and associated time base

A mechanical isotropic harmonic oscillator including a two translational degrees of freedom linkage supporting an orbiting mass with respect to a fixed base with springs having isotropic and linear restoring force properties.
