Systems for handling an event in a computer system which has a kernel-mode and a user-mode. The reservoir can be refilled by disengaging the implant from the stabilizer, inserting a new dosage of anti-angiogenic factor, and reconnecting the implant to the stabilizer or injecting a new dosage of anti-angiogenic factor into the reservoir through an injection port in the stabilizer. Conductivity enhancers may, also, be added. Multiple controllable light modulator elements located in a non-Fourier optical region may be adjacently stacked, spatially separated, or separated by GRIN material. If the change had a positive effect, the change management server may execute another script to make another network change.
