Latest Patents

Dong-Joon Kim holds a patent titled "Frequency tuning of disc resonator gyroscopes via resonator mass perturbation based on an identified model." This patent focuses on techniques for reducing the frequency split between the Coriolis-coupled modes in disc resonator gyroscopes (DRGs). The invention involves perturbing the mass distribution on the disc resonator based on an identified model. A model-identification method of tuning a resonator comprises perturbing the mass and measuring a frequency response matrix of the resonator. The frequency response matrix includes a plurality of inputs and outputs, and the resonator has multiple coupled resonance modes. A reduced structural mechanics matrix model of the resonator in sensor and actuator coordinates is identified from the measured frequency response matrix. This model is analyzed to determine generalized eigenvectors of the structural mechanics model and their variations due to selected mass perturbations, which are estimated to improve the degeneracy of the plurality of coupled resonance modes based on the generalized eigenvectors of the mass and stiffness. Dong-Joon Kim has 1 patent to his name.
