Abstract: The fuser members of this invention include a core member that includes a rigid outer surface. A resilient layer comprising an elastomer is optionally disposed on the cylindrical outer surface of the core member. A tie layer is disposed on the resilient layer or the outer surface if no resilient layer is present, the tie layer being made of fluoropolymers, fluoroelastomers, fluorocarbon thermoplastic copolymers and mixtures thereof. An outer layer of fluoropolymer resin made from polytetrafluoroethylene, polyperfluoroalkoxy- tetrafluoroethylene, polyfluorinated ethylene-propylene and blends thereof, is disposed on the tie layer.

Abstract: A method and apparatus for detecting anomalous cords in reinforced composites uses means to deform and/or vibrate the composite and detect the vibration signature of the composite. Broken or frayed reinforcement cords in a reinforced composite cause changes in the vibration signature of the composite, and the apparatus used in the method of the invention employs a low damping material which is used in proximal contact to all the reinforcement cords in the reinforced composite, and one or more sensors to detect said changes. The apparatus may also include a computer for collating data, analyzing data, and providing a signal when an anomalous cord is recognized.

Abstract: A sensor, and a sensor object combination, makes possible the collection of vibratory data from an object while reducing extraneous data and making easier the obtainment of the data. The sensor comprises an elastomeric housing which includes a concave cup portion, and pick-up devices for collecting vibration signals. The concave cup portion comprises a suction cup which makes possible vacuum attachment of the pickup device to the object being tested. The data signal may be amplified, analyzed, and ultimately the data may be analyzed by a computer.
