A method includes disconnecting a first component from a first network. The method comprises contacting said liquid composition with a functionalized resin. In one embodiment of the invention a pattern is formed in the asphalt surface using a removable template which is impressed into the asphalt when it is in a pliable state. And the first aperture through the solder mask exposes a plurality of the metal traces. A biasing unit biases the valve element to seat the valve element on a valve seat of the second passage. Packets may be injected into the network at injection points and statistics may be collected.
