Row electrode pairs and column electrodes are provided between the front glass substrate and the back glass substrate. This special plug connector has a plug connector housing with two bearing pins and a holding element for holding two respective ferrule housings. Then, an ITO defending layer and an indium tin oxide anode are defined simultaneously on the bonding pads and partial of the transparent insulating substrate surface, respectively. The passcode is received by another system, which authenticates the passcode by at least generating a passcode from a passcode generator, and comparing the generated passcode with the received passcode. In a fourth prevention technique, T-wave detection windows are applied to both the ventricular and atrial channels subsequent to any paced or sensed events. The methods are particularly useful for diesel particulate filters on diesel engines that are equipped with an exhaust gas recirculation system.
