Latest Patents

Among his latest innovations, Dummer developed a patent titled "Method of determining a dimension of a sample of a construction material and associated apparatus." This invention features an apparatus that determines the volume of a construction material sample by utilizing a sample-interacting device. This device interacts with the sample to determine surface characteristics, which are then used by a computer to create a three-dimensional representation and calculate the sample's volume. Additionally, this method allows for the determination of the mass and density of the construction material.

Another significant patent by Dummer is the "System and method for determining material properties of samples." This method focuses on nondestructively assessing the material property of porous samples. It employs a dual-vessel system where one vessel is evacuated while a greater-than-sub-atmospheric pressure is established in the second vessel containing the sample. Pressure equalization reveals vital data about the envelope volume and density of the sample, providing insights into its absolute density and relative absorption properties.
