20090216499 | ADAPTIVE FILTERING FOR MORE RELIABLY DETERMINING PHYSIOLOGICAL PARAMETERS - Apparatus for reducing an interference portion in a time-discrete signal further including a useful portion, including a first provider for providing the time-discrete signal including the interference portion and the useful portion; a second provider for providing a first time-discrete reference signal including a first interference portion, and a second time-discrete reference signal including a second interference portion, the second interference portion being shifted in phase relative to the first interference portion. The apparatus further includes a subtractor for generating a differential signal from the two reference signals, the differential signal including a frequency component caused by the first and second interference portions; and a manipulator for manipulating the time-discrete signal on the basis of the differential signal such that in a manipulated time-discrete signal the frequency component is reduced. | 08-27-2009 |
20100121207 | APPARATUS AND METHOD FOR DETECTING AN APNEA USING SIGNALS SENSED IN DEPENDENCE ON THE BLOOD PRESSURE - The existence of an apnea may be inferred when, in a pulse wave signal which is provided and is detected in dependence on the blood pressure, a change in a waveform of the pulse wave signal meets a predetermined detection criterion. | 05-13-2010 |
20100179439 | DEVICE AND METHOD FOR CORRECTING A BLOOD PRESSURE MEASURED - A device for altitude correction of a blood pressure measured at a measuring position of a living being has a transmitter, at least three receivers and an evaluating unit. The transmitter emits a signal from close to a measuring position and the at least three receivers receive the signal, wherein the receivers may be mounted to positions at different altitudes of the living being. The evaluating unit corrects the blood pressure measured on the basis of run time or phase differences of the signals received at the at least three receivers. | 07-15-2010 |
