A method for processing a physiological signal is provided. The method includes the following steps. A standard physiological signal as a first template to perform a first match filtering on an original physiological signal of a subject under test is used, thereby obtaining a first filtered physiological signal. A correlation evaluation on the first filtered physiological signal is performed and based on an evaluation result, whether interference has been sufficiently eliminated is determined. When determining that the interference has not been sufficiently eliminated, a personal physiological signal of the subject under test is used as a second template to perform a second match filtering on the first filtered physiological signal, thereby obtaining a second filtered physiological signal. A physiological parameter of the subject under test based on the second filtered physiological signal is generated.

A method and system for distilling alcohol in an alcohol production process utilizes mechanical vapor recompression (MVR), by way of an MVR device, such as to improve vacuum distillation column capacity. The MVR device is used as a way to increase vapor pressure/density and reduce vapor volume providing for increased volumetric flowrate and thereby increasing the capacity of a distillation system. In particular, the MVR takes a low value waste heat from stillage evaporators and compresses it to a higher temperature/pressure to create useful energy. By raising the pressure in the beer column with an MVR device, the vapor density increases, vapor volume decreases, and vapor velocity increases so that more vapor can be fed to and through the beer column. That is, additional mass flow can be added to the stillage evaporators and beer column to return the overall vapor velocity at the beer column to the original velocity constraint point. As such, the throughput of the beer column can be increased until it reaches its original velocity design constraint.

A storage system (20; 300) for storing loads (32) held by carriers (30; 330) has a plurality of uprights (46; 346) and a plurality of carrier supports (66; 366) mounted to the uprights. A plurality of flooring levels, one above another, are supported by the plurality of uprights and form a first bank (552A) and a second bank (552B) with a divide (550) between. A plurality of bridges (570) have deployed conditions spanning the divide and stowed conditions not spanning the divide. Shifting the plurality of bridges (570) between the deployed conditions and the stowed conditions engages or disengages a switch or triggers or untriggers a sensor. The engaging or disengaging a switch or triggering or untriggering a sensor causes a control system to route a wheeled automated vehicle driving around a stowed bridge.
