  • Transmitting and/or receiving unit for incorporation into an elastic structure
    Publication number: 20030085619
    Abstract: 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.

  • Method for the load-controlling operation of electromagnetically activated intake valves of an internal combustion engine
    Patent number: 6453856
    Abstract: In order to be able to implement low loads at high rotational speeds in an internal combustion engine with electromagnetically activated intake valves, one intake valve of a cylinder is operated in the free flying phase, i.e. not held in the open position, and the other intake valve of the cylinder is correspondingly opened for a longer time. Alternatively, the first valve can also be held closed.
