A cellular communicating device. The friction lining mounting sections have a T-shaped cross-sectional form defining an arcuate, radially outer platform for mounting a friction lining and a radially inwardly extending web. A pair of terminal leads are secured to a portion of the resistive element layer thus defining a termination area, and the termination area is positioned proximate the slot and away from the proximal end and the distal end of the sleeve. The stock is screened at a consistency of not less than 10%. The source computer dynamically decides whether each output packet will be a forward error correction packet or a single data packet, where the decision is based on minimizing the expected transmission delays. An air leak detection prohibiting module prohibits detection of an air leak at the intake manifold when the fuel cutoff indicating module indicates that fuel has been cut from one or more of the plurality of cylinders.
