    • 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.
    • 差压传感器具有第一和第二测量室。 每个测量室由刚性载体板和隔膜板限制,该板在测量室的区域中形成为压敏测量膜片。 为了设计差压传感器以防止过载,承载板布置在第一和第二隔膜板之间,并且在板的平面的相对侧上具有一致的凹陷。 凹陷通过偏心的管道相互连接,垂直于板的平面穿透载体板。 在测量室的区域中,隔板相对于凹陷形成为压敏测量隔膜。 测量室和管道填充有不可压缩流体。

    • 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.
