The tap changer (1) comprises a housing (2) with insulating fluid (3), a diverter switch (4) inside of the housing (2) and comprising at least one movable contact (MC, RC) and at least two vacuum interrupters (MV, RV), and at least one pressure sensor (5) which measures the ...
A monitoring device, comprising: a first input block (50) configured to obtain a first pressure signal (y) from a first pressure sensor (6a), which is arranged in an extracorporeal blood circuit (1a) to detect blood pressure variations that are pumped through a blood processing unit (5) in...
In one embodiment, the diagnostics are based upon a power signal which is a function of the frequency distribution of power of the pressure sensor output. For example, the circuitry 46 can perform a wavelet transformation, discrete wavelet transformation, Fourier transformation, or use other ...
Mid-IR laser absorption diagnostics for hydrocarbon vapor sensing in harsh environments These sensors provide the necessary sensitivity and time resolution for measurements in shock tubes, pulse detonation engines, and internal combustion engines. Different aspects of the research conducted are summarized bel...
desired for clinical diagnostics, which, however, may unavoidably necessitate an extensive battery and therefore, exhibit low biocompatibility. Thus, multimodal monitoring poses additional challenges for the transducers to possess the ability of intrinsic information decoupling, high biocompatibility, and ...
A pressure sensor comprising a pressure-displacement transducer mechanism including a movable body driven by a hydraulic pressure to be determined and spring means for urging the movable body in a direction opposite to the pressure, and a displacement-pulse phase conversion unit including a ferromagneti...
24. As another important piezoresistive pressure sensor, thin-film pressure sensors are based on the strain effect of metals and are widely used in the automotive electronics and aerospace fields, especially as ultralow-temperature pressure sensors. However, the fabrication cost is excessively high ...
ensuring that the sensor signal remains constant during the gripping process. In conclusion, positive experimental findings demonstrate that capacitive sensors have great sensitivity, rapid reaction time, and excellent cycle stability, making them ideal for medical diagnostics and human–computer interaction....
(as measured by a pulse oximeter attached to the fingertip), describe this erroneously as the PTT. In fact, this is the pulse arrival time (PAT), which includes not only PTT, but also the time delay between the electrical depolarisation of the heart’s left ventricle and the opening of ...
