A sprinkler structure includes a base with a rotatable stripe-shaped pipe and spraying pipes installed on the stripe-shaped pipe. The apex region includes a first apex portion and a second apex portion axially adjacent the first apex portion and a circumferential seam between the first apex portion and the second apex portion. Signed platform integrity information provides a measure of trust regarding the platform used to create the digital signature. The method discovers a physical path from the first node to the second node by automatically identifying nodes forming the physical path. If the data received on one path is \u201cbad\u201d and the data is \u201cgood\u201d on another path, the FTR transmits the \u201cgood\u201d data in place of the \u201cbad\u201d data.
