Patent ID: 7218439

Claim:
An oscillating device having an adjusted resonant frequency comprising: a pair of torsional hinges, each hinge of said pair of torsional hinges lying along a pivot axis and having first and second ends; an oscillating device connected between said pair of torsional hinges at said first end of each hinge of said pair and oscillating at a resonant frequency; first and second anchor members each of said first and second anchor members having a selected thickness and including a central portion and mounting portions joined by a connecting region of reduced stiffness, said central portion of each of said anchors connected to said second ends of said pair of torsional hinges and said mounting portions of each hinge mounted to a support structure; and a material applied over said connecting region of said anchor members to increase the stiffness between said torsional hinges and said anchor members with a resulting increase in the resonant frequency of said device.
