Abstract: The invention relates to a transponder that is mounted on a tire. The transponder includes at least one transponder chip and a transponder antenna and is embedded in a substrate which is connected to an inner side of the tire with the aid of an element. The aim of the invention is to provide a transponder with the highest possible durability. To achieve this, the connecting element is a material strip which is only fixed to the inner side of the tire in one sub-section.

Abstract: A method is provided for measuring the tread or profile depth of a tire in the operating state while the tire is rolling and in contact with a surface below it. Vibrations of the tire or tire parts, which vibrations are generated by the spacing and/or geometry of profiled elements of the tire tread, are detected while the tire is rolling and in contact with the surface below it. The detected vibrations are compared in an evaluation unit with a characteristic theoretical value/threshold value that corresponds to a vibration generated by a tread of adequate depth. The evaluation unit issues a signal if the detected vibration deviates from the theoretical value/threshold value.

Abstract: In order to rapidly and inexpensively deliver information regarding the load status of a motor vehicle, in particular, a utility vehicle with at least one axle that is suspended on pneumatic springs, there is arranged a sensor for measuring the bellows pressure and one additional sensor for measuring the spring travel on each of the pneumatic springs used in the wheel suspensions of the motor vehicle, and to additionally process the pressure and the spring travel in an electronic control unit. In this case, the spring forces preferably are calculated and displayed first, whereafter the wheel forces and ulitmately the position of the center of gravity, as well as the total weight and/or the weight of the net load, are calculated and displayed. The information regarding the load status preferably is also utilized as an input quantity for other safety systems, e.g., for lowering a lift axle, for issuing a warning and/or for throttling the speed in accordance with the respective requirements.
