Retirement ceremonies can be planned and executed by any Project Officer/NCO using this checklist. Deviations. may be necessary to tailor the ceremony to the individual, but the major items are included.
The ground is used for common mode rejection. The primary purpose of the ground is to prevent power line noise from interfering with the small biopotential signals of interest. By design, amplifiers should not be affected by large changes in potential at both the active and reference sites. A ground electrode for EEG recordings is often placed on the forehead (but could be placed anywhere else on the body; the location of the ground on the subject is generally irrelevant).
Grounding. Grounding creates a low-resistance path from a tool to the earth to disperse unwanted current. When a short or lightning occurs, energy flows to the ground, protecting you from electrical shock, injury and death. Grounding is a secondary method of preventing electrical shock. Grounded electrical systems are usually connected to a grounding rod that is placed 6-8 feet deep into the earth.
