摘要:
A differential pressure sensor has a first and a second measuring chamber. Each measuring chamber is limited by a rigid carrier plate and a diaphragm plate, which is formed in the region of the measuring chamber as a pressure-sensitive measuring diaphragm. To design the differential pressure sensor to be resistant to overloading, the carrier plate is arranged between a first and a second diaphragm plate and has congruent concave depressions on opposite sides in the plane of the plate. The depressions are connected to one another by a decentered duct, penetrating the carrier plate perpendicularly to the plane of the plates. In the region of the measuring chambers, the diaphragm plates are formed congruently in relation to the depressions as pressure-sensitive measuring diaphragms. The measuring chambers and the duct are filled with an incompressible fluid.
摘要:
There is described a capacitive differential pressure sensor made using glass-silicon technology with a diaphragm plate of silicon, which is arranged between two carrier plates consisting of glass. The diaphragm plate has pressure-sensitively deflectable regions, which are respectively provided with a capacitor arrangement. The capacitor arrangement is connected to a measured-value processing device through connecting conductors. To improve the ratio of the measuring capacitances to the parasitic capacitances brought about by the connecting conductors, the diaphragm plate is outside the pressure-sensitively deflectable region the substrate of an electronic circuit which comprises at least one input stage of the measured-value processing device.
摘要:
There is described a differential pressure sensor made using glass-silicon technology with a diaphragm plate arranged between two carrier plates. To achieve a high resolution at the beginning of the measuring range in conjunction with high overload resistance, the measuring diaphragm plate of the sensor has for a prescribed measuring range within the same measuring chambers a plurality of mutually independent deflectable regions as measuring diaphragms. Each such region acts as a part-sensor with a part-measuring range. The part-measuring ranges of the part-sensors overlap and in total are equal to the prescribed measuring range of the differential pressure sensor. The displacement of the measuring diaphragm of each part-sensor is mechanically limited outside its part-measuring range by the carrier plates.

Benzoylguanidines of formula I ##STR1## with R(1) to R(4) as defined in the specification, are suitable as antiarrhythmic pharmaceuticals having a cardioprotective component for infarct prophylaxis and infarct treatment as well as for the treatment of angina pectoris.They inhibit, in a preventive manner, the pathophysiological processes in the formation of ischemically induced damage, in particular in the elicitation of ischemically induced cardiac arrhythmias.
摘要:
Benzoylguanidines of the formula I ##STR1## in which: R(1) to R(4) have the meanings given in the claims, are antiarrhythmic pharmaceuticals, having a cardioprotective component, which are also valuable for the prevention of ischemically induced damage, in particular in association with the triggering of ischemically induced cardiac arrhythmias. As a consequence of inhibiting the cellular Na.sup.+ /H.sup.+ exchange mechanism, they are used for treating acute or chronic damage triggered by ischemia. In addition to this, they are notable for their strong inhibitory effect on the proliferation of cells. They are suitable for preventing the genesis of high blood pressure.

摘要:
Telemetry transmitting apparatus and a method are provided for reception and transmission of heart related electrical signals, such as electrocardiogram (EKG) and/or cardiac pacemaker signals, from a plurality of electrodes coupled to the body of a medical patient. A receiving facility of the apparatus receives a plurality of analog signals representing at least the EKG signals. An output signal representing the EKG signals is formed and transmitted, via a wireless coupling, to a telemetry receiver. An analog output port is provided on the telemetry transmitting apparatus. The analog output port is also coupled to the receiving facility. A plurality of output signals representing the EKG signals is provided to the analog output port of the telemetry transmitting apparatus. The analog output port may be coupled to buffers at the input terminals of the apparatus. Alternatively, the output port may receive processed signals from the amplifier in the telemetry transmitter that are gain adjusted to emulate the unprocessed voltage signals of the EKG electrodes and then combined with a digital pace pulse signal so that the output signals include pacemaker pulse information.
