A germbarrier travel kit sized, shaped and configured to carry articles necessary for germ prevention and sterilization. A palladium conductor layer is formed on the insulating part from a solution for palladium conductor layer formation which contains a palladium compound, an amine compound, and a reducing agent. A single virtual address representative of the pair of redundant linking devices may then be determined by the gateway device, and information associated with operation of at least one of the pair of redundant linking devices may be provided by the gateway device to an external system. Further input is received through a guided questionnaire based on the first level outputs. The device and the actuator implement the method.
