A phase locked loop generates a phase locked signal and adjusts a frequency of the phase locked signal according to an incoming signal. In addition, the application program may be executed according to program instructions stored in an application program file located in the remote device. The fiber materials are in particular fabrics, for example made of polyolefin. The polymer elements can seal against pressures greater than 5000 psi, and have a response time on the order of milliseconds. The reflector may be fed by one or more multiple-band horn antennas.
