Methods and systems for facilitating sign-on procedures in connection with a converged system are provided. The method includes exposing the ore particles to microwave energy and causing structural alteration of the ore particles. A coupling linkage is connected to the adjusting ring and includes two levers. By locating an interferometer and light source at a receiver, the light passes through the interferometer both before and after the optical link to the transmitter. These barriers are shaped so that only one of either a largest log or a smallest log, which it is expected that the singulator should handle, can rest on the primary lifting devices and be carried upward at a time. The housing also includes a locking wedge.
