The invention links or associates commands supported by application programs in the wireless device or by the platform itself to remote devices or to other application programs or similar processes by means of a software mechanism referred to as a bus. A configurable multi-stage mutation-based evolutionary algorithm optimally tunes the decision thresholds and internal parameters of fuzzy rule-based and case-based systems that decide the risk categories of insurance applications. The flexible segment is positioned on the support arm sufficiently near to the mounting attachment so the support arm will not constitute an elongated rigid obstruction in a bathroom.
