  • DETERMINATION OF SUBSTANCES IN AN ASSEMBLY
    Publication number: 20160063375
    Abstract: A processor identifies a component included in an assembly. The processor retrieves historical records that indicate which substances are included in the component. The processor determines a probability that the component includes the substances based on at least one historical record. The processor generates a list of substances included in the assembly based on the substances being statistically likely to be present in the component of the assembly.

  • Electroactive polymer compressed gasket for electromagnetic shielding
    Patent number: 7659483
    Abstract: A gasket for shielding a seam between two surfaces includes a resilient member, a first electrode, a second electrode and a conductive layer. The resilient member has a first side and an opposite second side. The first electrode is disposed on the first side of the resilient member. The second electrode is disposed on the second side of the resilient member. The conductive layer envelops at least a portion of the resilient member, the first electrode and the second electrode. The resilient member includes a material that is compressed when a first potential is applied between the first electrode and the second electrode and that is decompressed when a second potential, different from the first potential, is applied between the first electrode and the second electrode.
