The biodegradable heterophase compositions comprise partially or completely destructurised andor complexed starch, a polysaccharide ester and a plasticizer for the polysaccharide ester. The material of the reflecting mirrors, and the materials of the plate and the holding members have approximately equal coefficients of linear expansion. The modules can include a revenue generation module, a revenue capture module, a revenue collection module, a revenue intelligence module, and others. The source code is complied to create a connection information table for selecting the executable code modules and specifying their execution order. In some embodiments of the present disclosure, the electrical conductor has at least one gap separating the electrical conductor into at least two parts, thereby allowing a current to flow through the at least two parts in parallel to generate a magnetic field in the insulating body.
