A method for conserving power begins by measuring processing speed of at least a portion of an integrated circuit to produce measured processing speed. A lifting beam is movable by a drive mechanism along the longitudinal members and supports, directly or indirectly, a handling device. Wherein each output driver stage has a defined current drive capacity that is output to the select output port in response to the control signals. The method includes: computing a cryptographic value for the selected log entry; and determining if the cryptographic value is part of another recorded log entry. The hood and fill structure cooperatively define restricted flow paths for the waste water-solids suspensions, and assist in the creation of relatively high velocity movement of the suspensions to prevent bridging or clogging by collective solids adjacent the bottom of the tanks.
