A spatial multiplex base station estimates an optimal array parameter appropriate to a propagation environment of a received signal and changes the array parameter in an adaptive manner. The inventive method involves the use of these monitors andor decontamination means in intermodal containers of mobile-unit structures dedicated to responding to radiological emergency situations. A hairspring has a central portion fixed to the balance with hairspring and an outer portion fixed to the hairspring holder. The aggregated first classification determinations are compared to a first predetermined threshold to determine a validity of the decoded barcode estimation. The primary axis body of the dual-axis case-grounding pins fits around a PCBA notch while the secondary axis passes through a metalized alignment hole for grounding.
