Abstract: A slave station and a method of regulating the transmission power a master station are described, which permit an estimate of the signal/interference ratio in a transmission system without sending a pilot sequence, the transmission power being regulated as a function of an estimate of the signal/interference ratio. In a transmission system, in particular a CDMA transmission system, useful signals assigned to different communicating subscribers are separated by orthogonal codes. A useful signal assigned to one communicating subscriber is derived by using one of the codes from a signal received at least in the slave station from the master station and is compared as a reference signal with the received signal to estimate the signal/interference ratio.

Abstract: A method and system for indicating a discrepancy between driving data captured using a tachograph and at least one prescribed rule by an indicator appliance independent of the tachograph. The indicator appliance is connected to a tachograph data memory that has the driving data. By virtue of detachable electromechanical coupling of the indicator appliance to the tachograph data memory that is automatically followed by at least one driving data volume element being loaded into an appliance data memory of the indicator appliance and automatically compared with at least one rule. The presence of a discrepancy between the loaded driving data volume element and the rule prompts the presence of the discrepancy to be transmitted to a user of the indicator appliance as a violation report.
