A board includes a pattern to facilitate attachment of the board to a frame structure using fasteners. The body is provided with one groove extending partly over the two faces of the body and one of the two connecting regions, wherein the one groove extends approximately in a plane at right angles to the axis of the body with a depth which is variable between a first depth P1 in the two faces of the body and a second depth P2 in the connecting region. The communications component is operable to receive the message from the mobile switching center. If both of the paired peaks are determined as being candidates for unwanted peaks, it is determined that the peaks are unwanted peaks. In some configurations, each of the first chamber and the second chamber may form portions of upper and lower surfaces of a pneumatic component.
