A method and apparatus of coordinating operation of two or more subsystems implementing different wireless communication protocols is disclosed. The first operation deposits barrier material via PVD or CVD to provide some minimal coverage. A request for a certificate validation result is sent to the host. It is determined whether the third ink point adequately fits the active B\xe9zier approximation. This may be done, for example, by another processing device, such as a host CPU, or any other suitable processing device. The outdoor textile fabric may be prepared by treating the front surface of the textile fabric with an aqueous treatment composition containing a fluorochemical agent and applying a second treatment composition containing a polyurethane to the back surface of the textile fabric.
