This invention relates to novel free-flowing filler compositions containing sulfur-containing silane coupling agents, and to a rubber containing the filler composition. By the present invention, a baking process for thickness reduction is not required after applying the solution. The FMRE determines a plurality of evidentiary-failure-mode-probability rectangles based on the evidence notification. The method may further include, at the OLT: receiving the second authentication message; calculating a second authentication code by using the first random number and a secret code stored at the OLT; and authenticating the optical termination device if the first authentication code matches the second authentication code. The transducer system is configured to send signals into the object and receive a response to the signals.
