The possibility of special lightening, insulating and reinforcing intermediate floor constructions enables fast building of semi-prefibraceted and prefabricated floor with complete insulation, bearing capacity and smaller price. More specifically, the present disclosure provides an orthogonal polarization detection and broadband pilot technique for the compensation of nonlinear cross polarization induced noise and nonlinear nonlinear cross phase modulation induced noise in a high data rate polarization multiplexed multilevel-quadrature amplitude modulated channel due to neighboring channels. The method allows dopant gas and vapors to be distributed in such a way as to cause efficient reaction of dopant gas or vapor molecules with electrons created by a filament contained in the arc chamber. The microneedle array is then pressed towards the skin. If not, the measurement capacitors are all reset without their signal values being measured, and the controller re-drives the same X line to initiate another charge transfer into the measurement capacitors for that X line. An associated datalogger unit on each container connected to the sensor unit collects and transmits sensed temperature and humidity data at timed intervals via radio link to a remote monitoring station including a pc for recordal andor display.
