A novel inbred maize line designated PHCCW and seed, plants and plant parts thereof. The isolator mount system is preferably configured to shift frequencies at predetermined displacements upon impact, at or before the system attains resonance. A stainless cap may provide an attractive top surface into which a logo or symbol may be embossed. More specifically, in one embodiment, there is provided a method comprising receiving a packet transmitted over an air interface, computing a probability that the packet has a same actual power offset as a previously decoded packet based on one or more previously received packets, and calculating a signal power estimate based on the transition probability. In other embodiments, other disposable items such filter andor additional light source may be provided. A solderable contact layer is then formed over the passivation layer.
