  • Systems and methods for screening particle source manufacturing and development test data
    Patent number: 11719727
    Abstract: A computing system obtains test data for a particle source. The test data was generated by the particle source when the particle source was caused to emit particles. The test data comprises a first set of measurements of a first type and a second set of measurements of a second type. The computing system applies a data agnostic predictive model to the test data. The data agnostic predictive model is generated without a parametric analysis of variables of the first type and variables of the second type. The data agnostic predictive model outputs, based upon the test data, a value that is indicative of whether or not the test data is abnormal. Based upon the value, the computing system outputs an indication that the particle source was operating sub-optimally when emitting the particles.

  • Elastomer coated layer for erosion and/or fire protection
    Patent number: 5912195
    Abstract: A method for preparing an uncured supported elastomer material includes the steps of: providing a fibrous reinforcement material; providing a layer of uncured elastomer material substantially adjacent to the fibrous reinforcement material; exposing the layer and the fibrous reinforcement to a temperature below a curing temperature and above a flow point of the uncured elastomer material, and a pressure sufficient that the uncured elastomer material flows into the fibrous reinforcement material, so as to provide an uncured supported elastomer material.
