摘要： The invention relates to a device for determining the inexact placement of measuring points on measuring sensors and for reducing measuring errors, which result from the movement between the measuring points and the measuring sensors when measuring the most diverse quantities to be measured, with the aim of creating robust measuring systems for recording measured values under real or difficult conditions. The invention is characterized by: detecting whether and which sensor elements are covered and thus in contact with the point to be measured; tracking and/or adapting the sensor elements so that the contact is not interrupted even during movements, and; the resilient arrangement of the contacts for constantly maintaining the mechanical bearing pressure when measuring the electrical skin resistance. The measurement data are processed further by software that determines the area of contact from the signals of the device and from the knowledge of the arrangement of the measuring elements, and uses the completely covered sensor elements determined thereby in order to conduct measurements with the fewest possible number of errors.

摘要： Methods and devices configured for analyzing sensing vectors in an implantable cardiac stimulus system. In an illustrative example, a first sensing vector is analyzed to determine whether it is suitable, within given threshold conditions, for use in cardiac event detection and analysis. If so, the first sensing vector may be selected for detection and analysis. Otherwise, and in other examples, one or more additional sensing vectors are analyzed. A polynomial may be used during analysis to generate a metric indicating the suitability of the sensing vector for use in cardiac event detection and analysis. Additional illustrative examples include systems and devices adapted to perform at least these methods, including implantable medical devices, and/or programmers for implantable medical devices, and/or systems having both programmers and implantable medical devices that cooperatively analyze sensing vectors.

摘要： A device to carry out a bioelectrical interaction with an individual by means of electrodes 29, 29a whereby an on-demand verification of the integrity of the electrical contact of the electrodes is implemented. The device 20 comprises a control unit 22 arranged to determine an occurrence of the predefined event related to a quality of a measured signal. In case the predetermined event is detected, the control unit 22 actuates the testing means 24. The testing means is arranged to generate the test signals, I1,12 and to apply them via a coupling circuit 23, 23a to the electrodes. In case it is desired that cumulative information about the contact integrity is obtained, is it sufficient to apply a single test signal per electrode. In case it is required to determine which of the electrodes has lost its contact, a sequence of test signals is generated by the sequencer 24b. The response signal from the electrodes 29, 29a is forwarded to the input filter 26, which is preferably also used for a normal signal analysis. The signal from the input filter 26 is directed via the input impedance 25, 25a to the input amplifier 28. The amplified response signal is forwarded to the signal processing means 30 which is arranged to analyze the response signal. Preferably, an amplitude analysis is done. The signal from the signal processing means 30 is supplied to the analog-to-digital converter (ADC) 32 after which a digital processing of the response signal is carried out by means of a further processing unit 34. In case the further processing unit 34 determines that the integrity of the contact is below the allowable level, the lead-off indicator 36 is actuated.

Such a system includes a comparator (306) for performing a comparison of a low frequency differential signal derived from at least two of the patient attachable electrodes with a predetermined threshold signal (DT) and a decision processor (308) for generating a signal indicating an electrode signal is at least potentially degraded in response to said first comparison. Preferably the system further comprises

a second comparator (210(a)) for performing a second comparison of a low frequency signal derived from one of said patient attachable electrodes with a second predetermined threshold signal (AT) and the
decision processor generates a signal indicating an electrode signal is at least potentially degraded in response to said first and said second comparisons.
