Abstract: A base plate, which is made of plastic and is intended for supporting a rail for a rail vehicle on a substrate, may include a lower face, and an upper face on which a supporting surface for the rail is formed, a recess, from which a passage leads to the upper face of the base plate, being formed in the lower face of the base plate, the diameter of the recess in a direction transverse to the longitudinal axis of the passage being greater at least in part than the diameter of the passage, so that a stop for an insert piece fitted into the recess is formed on the top surface, assigned to the upper face of the base plate of the recess.

Abstract: A serial transmission controller for processing data transmissions between a memory and an external device is provided. The serial transmission controller includes a microcontroller, a scheduling unit, a transmission unit, and an interception control unit. The microcontroller obtains pipe data from the memory. The microcontroller reads a transfer request block from the memory according to the pipe data. The scheduling unit generates a transmission request according to the pipe data and the transfer request block. The transmission unit transmits a packet of the transfer request block according to the transmission request, and correspondingly generates a transmission response. When the interception control unit receives the transmission response, and the data length that has not been transmitted in the transfer request block is greater than 0, the interception control unit notifies the transmission unit to continue to transmit a next packet of the transfer request block.
