Systems and methods for distracting an intervertebral disc space are provided. The systems use a staged, bilaterally expandable trial. The systems and methods of distracting an intervertebral space are provided in a manner that addresses the problem of subsidence. The method includes inserting the trial into the intervertebral space in a collapsed state and, once inserted, the trial is then used for distracting the intervertebral space using an expansion that includes a first stage and a second stage. The first stage includes expanding the trial laterally toward the peripheral zones of the top vertebral plate and the bottom vertebral plate, and the second stage includes expanding the trial vertically to distract the intervertebral space.

A method for depositing a film on a substrate using a plasma enhanced atomic layer deposition (PEALD) process includes disposing the substrate in a process chamber configured to facilitate the PEALD process, wherein the process chamber includes a substrate zone proximate the substrate and a peripheral zone proximate to a peripheral edge of the substrate. Also included is introducing a first process material within the process chamber, introducing a second process material within the process chamber and coupling electromagnetic power to the process chamber during introduction of the second process material in order to generate a plasma that facilitates a reduction reaction between the first and the second process materials at a surface of the substrate. Electromagnetic power is coupled to a process electrode to generate a substrate zone plasma in the substrate zone that ionizes contaminants substantially in a region of the substrate, and electromagnetic power to a peripheral electrode to generate a peripheral zone plasma in the peripheral zone having a characteristic different from the substrate zone plasma such that ionized contaminants are transported from the substrate zone to the peripheral zone in the process chamber.

A display unit comprises a display region constituted of twenty-four display segments each of which has a triangular display surface. The display region consists of a quadrangular central region and a quadrangular and annular peripheral region surrounding the entire central region. The central region has two quadrangular portions arranged one above the other. Each of two quadrangular portions consists of four display segments. The peripheral region is constituted of sixteen display segments.
