| 20080205446 | Method and Device for Data Transmission Between Two Components Moving Relative to One Another - In a method and a device for data transmission between two components moving relative to each other, a first of the components has a number of transmission segments arranged along the movement direction and a second of the components has receiver units arranged along the movement direction. The data to be transmitted are divided among several transmitter segments for parallel transmission thereof. The data to be transmitted are configured in respective data packets, each having a packet identifier in addition to a data portion. A receiver device connected to the receiver units assembles the respective data portions of the respective received packets in a correct sequence using the respective packet IDs. The need for a position detector for noting the relative position of the transmitter segments and the receiver units is avoided. | 08-28-2008 |
