Latest Patents
One of his latest patents is titled "Method and apparatus for determining the fundamental viscoelastic properties of a viscoelastic material." This innovative method involves imparting a torsional stress in a viscoelastic material and measuring the relaxation of that stress over time. The process includes converting the relaxation stress to a representative analog waveform, digitizing it, and determining the frequency-dependent fundamental viscoelastic properties based on the waveform's shape. This method facilitates automation by analyzing the waveform to detect the start and end of tests, ensuring valid results.
Another significant patent by Porter is "Determining the air permeability of a tire." This invention involves mounting a tire in an inflated condition and utilizing sensors to measure fluid pressure and temperature. The data acquisition system converts these signals into digital information, allowing an electronic digital computer to calculate a corrected pressure value. This value is then linearized to indicate the rate of change of pressure in the tire, enhancing tire safety and performance.
