In a composition of forming a passivation layer, the composition includes about 30 to about 60 percent by weight of a mixed polymer resin formed by blending polyamic acid and polyhydroxy amide, about 3 to about 10 percent by weight of a photoactive compound, about 2 to about 10 percent by weight of a cross-linking agent and an organic solvent. A networked computers system including various devices is monitored for alert conditions associated with one, or more, of the devices. In another, it is by correcting for clock differences. The stress relieving layer serves to prevent peeling of the passivation film. The positioning device is operative to secure the lid at an open position.
