Sensorsystem und Verfahren zur kapazitiven Messung elektromagnetischer Signale biologischen Ursprungs

WO2006066566 A UPAB: 20060814 NOVELTY - The shielding agent contains electrode device (10) and the signal-processing device, which is detected by the sensor system. The electrode device measure the parasite arene bleeder of the device forms a high-pass with a critical frequency adapted to the signal. The device is arranged in the housing where the ohms resistance is very high capacitive into the entrance of the signal-processing device. The system exhibits an electrical insulator range for separate the signal source. DETAILED DESCRIPTION - The isolator area exhibits a static loading of the insulator range minimized by static environment charges. The signal processing contains an analog-digital transducer and a digital signal processor. A jerk coupled of processed signals intended on the mechanism over a capacitive, resistive/inductively realized compensation impedance (Ck). The signal-processing device is separating dynamic measuring signal by direct current voltage. A line conduction shielded on mass potential, to lead away the measuring signal from the sensor system. The sensor system cooperates with a reference electrode is used for linking a change signal (a (t)), and (B (t)) and fasten the system to a measuring object (Q) supplied with a reference potential. INDEPENDENT CLAIMS are also included for: (1) a measuring device; and (2) procedure for minimizing the influence of movement articate. USE - Used for the capacitive measurement of electromagnetic signals of biological origin e.g. EKG, ECG signals. ADVANTAGE - Improved system and accurate signals
