According to one exemplary embodiment, a method for VIOS failover in an environment with a physical storage adapter is provided. Each inclination angle adjustment block has a core shaft defining an axis line, and a plurality of bearing faces connected to one another and respectively disposed in parallel to the axis line and adapted for selectively supporting the tread platform on the ground. The first filter has a higher-frequency passband than the second filter. The digital outputs are seamlessly merged to produce an output that can be displayed as a scan display which shows the location of faults. That timing mechanism can be reset from a few minutes to several hours therefore gradually reducing the absorption of nicotine until the craving for it is negligible and quitting the habit is easy.
