A composite building component includes a non-planar molded composite web having two outer zones and two angled zones wherein the caliper of the angled zones differs from the caliper of at least one of the outer zones, and a flange disposed on an outer surface of an outer zone. The apparatus may further comprise a control unit configured to select one of the plurality of filters depending on a strength of the first signal. According to the present invention, the coating film can be planarized without using the CMP apparatus. In the method for encryptingdecrypting packet data of the precise time synchronization protocol, an encryptiondecryption hardware device is disposed on the hardware protocol layer of each of the master node and the slave node.
