The present invention pertains to a coating composition for the coating of a substrate such as a mirror or a glass. The method includes executing sets of sequential instructions, each execution being based on a unique initial value, generating a computed final value responsive to each execution of a set of sequential instructions, and sending computed values to a monitoring portion of a high integrity processor monitor system responsive to the generating for each execution of the set of sequential instructions. The elongated body has a nozzle end at one end and a connection portion at another end. An arrangement of embedded non-olefin fiber elements extends in anchored relation at least partially across the thickness dimension of the mat structure. A cover shields the busbar from inadvertent contact and includes a small diameter aperture to permit access to the measurement region of the busbar. The network includes a series of electrical devices, and fiber optic connectors between electrical devices of the series of electrical devices forming a closed communication ring in which output of each electrical device is communicatively connected to input of a subsequent electrical device of the series of electrical devices.
