Abstract: The invention concerns a method and a device to measure the speed (v) of a vehicle relative to a road surface. To increase the accuracy of the speed measurement and in order to be able to determine the speed (v) of the vehicle independently of the diameter and the adhesion of a vehicle wheel on the road surface, the invention proposes that the speed (v) of the vehicle is measured directly on the road surface by utilizing the Doppler effect.

Abstract: The invention concerns a device for measuring the time delay between a first periodic pulse signal (2) and a second periodic pulse signal (5) having the same frequency as the first pulse signal (2). In order to determine the time delay between the two periodic pulse signals (2, 5) in as accurate a fashion as possible, the invention proposes a device which is characterized by means for producing a periodic diagnostic signal (18), having half the frequency of the first pulse signal (2), whose sampling ratio is a measure for the time delay between the first pulse signal (2) and the second pulse signal (5) as well as means for determining the sampling ratio of the diagnostic signal (18) and means for determining the time delay between the first pulse signal (2) and the second pulse signal (5) from the sample ratio of the diagnostic signal (18).

The amplitude of the signal received is a function of the distance of the object from the receiver. A circuit is provided for the adaptation of the signal to a reference signal.

Abstract: A method for deriving a respiration signal and/or a cardiac artifact signal from a physiological signal, in particular an impedance pneumography signal, includes detection of a heartbeat moment, storing the amplitude of the physiological signal at the heartbeat moment, and calculating and storing a learning signal, the learning signal being a function of a previous learning signal and the difference between the instantaneous amplitude of the physiological signal and the stored amplitude thereof. The learning signal is either read out starting each time with the particular heartbeat moment, for deriving the cardiac artifact signal, or subtracted from the physiological signal at each heartbeat moment for deriving the respiration signal.
