Abstract: It is proposed to assign a mounting arm to a toll calculator which is embodied as a surface-mounted device and which is connected in an articulated fashion to the toll calculator and can be mounted on the windshield of the motor vehicle. The toll calculator itself then rests with a relatively small area on the dashboard of the motor vehicle with the intermediate connection of a preferably elastomer supporting element which is preferably coated with adhesive on two sides.

Abstract: A data-transmission device has a pulse generator (1) and a monitoring unit (20) for use in a vehicle. A signal generated by the sensor (2) is transmitted from the pulse generator (1) to the monitoring unit (20) by a signal line (9) and also, when requested by the monitoring unit, is transmitted in encrypted form along a data line (19). The signal generated by the pulse generator (1) is first stored in an intermediate store. Before transmission, the contents of this store are encrypted. On arrival in the monitoring unit, the encrypted signal is compared with the signal previously transmitted in the usual way and recorded there. This is a security check which reveals any manipulations which have been made during transmission.

Abstract: The arrangement, according to the invention, includes a positioning drive with which a record chart bundle is drivable in a recording movement direction when it is received on a centering pin which can be raised and lowered, an adjustable stop which rotates at the recording speed and compensates for an angular difference between the recording angle per record chart and a complete revolution of this record chart, a catch arm, which is formed on at the stop, cooperating in turn with a radial edge of a sector-shaped cut-out portion of the uppermost record chart in the bundle during the positioning, the sector shape being conventional in record chart bundles, and driving means which are active when a record chart bundle is positioned and which couple the record chart bundle with the recording drive, the driving means being rotatably supported at a web which is movable vertically at the centering pin.
