A dust filter bag having a highly porous backing material ply and a method for producing the dust filter bag. The method also includes adjusting the encoding parameter based at least in part on the determined operating characteristic and while maintaining the first video quality, and encoding the video data at the first video quality using the adjusted encoding parameter. The fixing screw is tightened with a defined torque such that, due to the resultant defined contact pressure, a defined resistance for discharging electrostatic charges from the electromotor is obtained. The tire has a second tread zone with no lugs or grooves. Upon wrapping the first Velcro strap about the stock, a releasable connection occurs between the Velcro straps with the male fastener in extension from the stock. In addition, a comparator stage is provided whose switching threshold is set lower than the reference voltage by using a voltage divider that is connected to the reference voltage.
