Abstract: In a method and apparatus for determining a physiological activity signal in a subject using various movement sensors that each transmit a temporal movement signal, a physiological reference signal is determined from the various movement signals that best depicts a physiological movement of the subject, the movement sensor that generates the physiological reference signal is identified as a physiological reference sensor, at least one physiological addition signal is determined from the temporal movement signals that is similar to the physiological reference signal up to a limit, and the physiological reference signal and the at least one addition signal are added to form the physiological activity signal.

Abstract: In a method and medical data acquisition system for the correction of interference signals (in particular those caused by gradient coils) in a magnetic resonance apparatus given the determination of a point in time in the cardiac cycle of a patient by the acquisition of cardiac noises with a sound sensor arranged on the patient, a calculated and/or pre-measured interference signal that describes the interference noise of the gradient coils is obtained and is subtracted from a raw signal measured by the sound sensor.

Abstract: The present invention includes a method and apparatus for cleaning exhaust of an internal combustion engine. The internal combustion engine has a catalyst and a lambda probe disposed in an exhaust gas tract. The lambda probe is disposed upstream from the catalyst, and is capable of an output &lgr;o substantially close to lambda=1. The present invention includes determining a relationship between a downstream NOx concentration and a lambda value such that a lambda value substantially greater than 1 indicates a substantially greatly increased NOx concentration, and determining a relationship between a downstream NH3 concentration and a lambda value such that a lambda value substantially less than 1 indicates a substantially greatly increased NH3 concentration.
