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).
In my area, a homeâs gas and metal water lines, as well as cable TV and phone lines, are required to be bonded to the grounding electrode. Itâs always wise to check with the local JHA to determine which grounding methods, including Ufer grounds, are approved in the local jurisdictions.
