Latest Patents

Kurihara’s listed patent, “Body dynamics calculation method, body dynamics model and model data thereof, and body-model generation method,” describes techniques for performing forward and inverse mechanics calculations on detailed human-body models.

The method uses bone geometry alongside muscle, cord, or band data. It calculates how forces applied through wires or virtual links affect the body model, using a Jacobian to convert those forces into generalized forces. The system then determines the resulting acceleration and calculates the velocity and position of each rigid body link.

The patent also describes generating a new body model from a new skeleton geometry. By mapping the new skeleton to a predefined normal-body model, the method can automatically produce a corresponding model for further calculations.
