Latest Patents
One of Christy's notable inventions is the "Portable Universal Friction Testing Machine and Method." This friction testing machine is designed to measure the friction characteristics between a test sample and a friction surface. It is particularly effective for assessing the coefficient of friction between rubber specimens or tread elements and various friction surfaces at different sliding velocities, contact pressures, and orientations. The machine is self-contained and portable, allowing for easy and quick changes of the friction surface. It also features a sample holder that maintains frictional engagement with the friction surface and a motion device that facilitates relative movement between the two.
Another significant patent is the "Method for Predicting Tire Performance on Rain Groove Roadways." This method allows for objective testing of tires in a laboratory setting, closely correlating with subjective field analysis data. By simulating rain groove road conditions, the method enables the prediction of tire performance without the need for extensive field testing. This innovation not only reduces costs associated with tire design and testing but also streamlines the implementation of tire design testing.
