A system for monitoring conveyor belts is disclosed. The system includes a printed inductive antenna loop, a transmitter, a detector, and circuitry. The antenna is printed on and/or installed (inserted) into a conveyor belt. The transmitter is proximate the printed antenna and is configured to generate an electromagnetic field. The detector is configured to measure an induced electric field from the printed inductive antenna loop. The circuitry is configured to detect damage of the conveyor belt based on the measured induced electromagnetic field.

A method for controlling or regulating a level control system for a motor vehicle including a compressed air source, at least one air spring, a switchable directional control valve associated with the air spring and a master line connecting the compressed air source to the switchable directional control valve. The switchable directional control valve blocking the master line in a normal state thereof and connecting the master line through for filling the air spring in a switching state thereof. The master line is filled with compressed air before filling the air spring until the air pressure in the master line is at least equally as high as a predetermined threshold value, and only thereafter is the switchable directional control valve transferred into the switching state for filling the air spring. A level control system for a motor vehicle is also provided.

An air spring has at least one working space which is filled with compressed air and which is delimited at least partially by a rolling bellows which is fastened at its ends to connecting parts. At least one of its ends, the air spring has a wall which is thicker in relation to the rest of the rolling bellows body, wherein the rolling bellows has, at least one of its thickened ends, a continuously vulcanized layer cover which is folded back to such a length that, after the assembly of the air spring, at least one region of the rolling bellows which is highly loaded by chassis forces falls into the region of the layer cover.

Motor vehicle equipped with a pneumatic level control system
Disclosed is a pneumatic level control system equalizer of a motor vehicle equipped with a battery and a generator supplying the battery, as well as a compressor driven by an electric motor and associated with the level control system equalizer, the electric motor of the compressor being only supplied with electric current by the vehicle battery and/or generator in certain conditions. The power requirements of the level control system equalizer can be pre-evaluated for a change of level and/or a filling of the pressure tank to be performed.
Tire having a tread pattern with superior performance characteristics. The tread pattern includes ribs and circumferential grooves which are at least one of tapered and/or generally V-shaped. The walls of each circumferential groove have a wavy and/or sinusoidal contour extending in a generally circumferential direction.
