For producing large volume optical components of high optical quality from synthetic quartz glass blanks, the latter are heated in a component mold in a furnace with a protective gas atmosphere to a temperature 50\xb0 to 170\xb0 K above the softening point, this temperature being held for 20 to 90 minutes and, during this holding time, the quartz glass blank being pressed into the component mold. Upon cooling of the probe, engagement of the probe with the contact is reestablished. By selecting proper coefficients for the linear combination and choosing probable transmitted signals that minimize a minimum mean squared error function, the signals of the various terminal units are canceled when detecting the signal of a particular unit. When the shunt switch is opened, energy stored in the inductor is suddenly delivered to the diode array. That is, sibling peer-to-peer connections with the same device may be treated different from other non-related peer-to-peer connects for purposes of interference mitigation in a wireless network.
