摘要:
The procedure and the facility are used for wireless transmission between a wheel module (9) arranged in a tire (2) and an external control device (3). A first transmission signal is transmitted from an antenna (6) of the control device (3) to an antenna (11) of the wheel module (9). Data is transmitted via a second transmission signal from the wheel module (9) to the control device (3), whereby the first transmission signal has a different frequency from the second transmission signal. The first transmission signal is received by the antenna (11) of the wheel module (9) during a coupling period, within which while the tires (2) are rotating, an area of influence (15) of the antenna (11) of the wheel module (9) which also rotates, and a stationary area of influence (14) of the antenna (6) of the control device (3) overlap. After the beginning of the coupling period is recognised, the data transmission is started from the wheel module (9) to the control device (3).

The invention is directed to a transmitting and/or receiving unit for building into an elastic structure. The transmitting and receiving unit includes one or more electronic circuits or circuit elements and, if needed, sensors and/or signal elements assigned thereto. The transmitting and/or receiving unit has one or several antennas connected to the electronic circuit. The antenna includes one or several filaments which are so arranged in the surface or in space that the main directions of the stresses and forces, which occur within the surrounding elastic structure/matrix, essentially intersect or cross the filament axes.

The invention relates to a method for producing light-conducting LED bodies by injection molding into a mold of a material that is fusible prior to final solidification. Each LED body comprises at least one light-emitting chip and at least two wire-shaped electrodes that are electrically connected to the chip. The injection mold is evacuated via at least one opening per LED after positioning the electronic parts and closing. The evacuation opening is disposed in the proximity of the electrodes in the bottom area of the LED. The fusible material is injected between the bottom area and the chip or the reflector trough at least approximately parallel to the chip surface and at least approximately normal to a surface embodied by two electrodes, with the center line of the injection stream running between two electrodes. The inventive method for producing light-conducting LED bodies prevents the LED electronics from being damaged during normal performance of the injection molding process.

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.
