Real-time monitoring of tissue ablation is possible by using a vibrating ablation needle coupling lateral shear waves to the tissue. The laminate veneer sheet thus created exhibits at least one substantially transparent viewing surface, combined with an opaque interior and which is capable of being coiled about its least planar dimension to a diameter lesser than the dimension. The method further includes initiating a barometric correction value of the serving fixed local transceiver to the combined barometric correction value, and sending an indication of the barometric correction value to the plurality of client fixed local transceivers. The relationship between parent and variant objects is maintained regardless of the location where the objects are stored. The elements which measure, handle and digitize the signal in order to convert it into a digital signal are placed close to the measuring electrode.
