In order to measure a surface profile of a sample, an imprint of the surface profile to be examined is produced in a transfer material. In general, it is a device used to stabilize the presence of vaso-occlusive devices in the aneurysm. The meter electronics further includes a storage system configured to store flow meter parameters and data. The hand guard assembly can also include a hand guard having a receiving channel about an interior portion of the hand guard. Accordingly, the space can be increased and program disturbance in the region in which the word line will be formed can be prevented. In some embodiments, a method may comprise predicting, by a current control logic, a potential voltage transient on a power supply bus, and modulating, by the current control logic, a current source, based at least in part on said predicting, to control the predicted voltage transient.
