  • Patent number: 9730333
    Abstract: A solution of metal ink is mixed and then printed or dispensed onto the substrate using the dispenser. The film then is dried to eliminate water or solvents. In some cases, a thermal curing step can be introduced subsequent to dispensing the film and prior to the photo-curing step. The substrate and deposited film can be cured using an oven or by placing the substrate on the surface of a heater, such as a hot plate. Following the drying and/or thermal curing step, a laser beam or focused light from the light source is directed onto the surface of the film in a process known as direct writing. The light serves to photo-cure the film such that it has low resistivity.

  • Patent number: 9050871
    Abstract: A method for temperature compensating an air spring of an air spring suspension of a motor vehicle after engine shut-off. A desired trim height is obtained. At engine shut-off, the ambient temperature is measured and the temperature of air in the air spring determined. After a wait time (for loading/unloading), a start trim height is measured. A predicted trim height is determined for when the air in the air spring is at the ambient temperature. Finally, the volume of the air in the air spring is selectively adjusted so that when the air in the air spring arrives at the ambient temperature, the trim height will be about the desired trim height.
