During pulse signal collection, width information of waves is essential for the diagnosis disease. However, currently used measuring instruments can only detect amplitude while can't acquire information. This paper proposed a novel wrist acquisition system, which could realize simultaneous measurements and dynamic under different static forces. A tailor-packaged micro-electro-mechanical system (MEMS) sensor array was employed to collect signals, conditioning circuit designed process...
The respiratory signal is a critical index of cardiopulmonary function. In this paper, we implement the polyvinylidene fluoride (PVDF) sensor to collect data pulse waves and reference respiration signals. correlations between major feature values breaths are investigated presented. As result, several exhibit relatively good with amplitude. improvements Kalman Filter for signals extracted from value variances also introduced. Moreover, display comparisons low-pass filtering, Wavelet ensemble...
A radial artery above the styloid process is called GUAN and a critical position for collecting pulse wave in traditional Chinese medicine theory. Locating precondition wave. However, existing methods locating lead to large deviations. This paper proposes novel nontouch method based on thermal imaging image processing. consists of three parts: infrared location platform, wrist edge contour extraction algorithm arbitrary angle recognition, protrusion recognition (x coordinate identification...
In pulse waveform classification, the convolution neural network (CNN) shows excellent performance. However, due to its numerous parameters and intensive computation, it is challenging deploy a CNN model low-power devices. To solve this problem, we implement accelerator based on field-programmable gate array (FPGA), which can accurately quickly infer category. By designing structure of CNN, significantly reduce premise high accuracy. Then realized FPGA optimized by variety memory access...
Pulse waves of a radial artery under different pressures applied through cuff play an important role in disease diagnosis, especially traditional chinese medicine (TCM). could be collected by pressure sensor array affixed to inflatable cuff. During process collecting pulse waves, one moves up and down when the is shocked wave. Movement leads passive displacement other nearby sensors because connecting structure between them. Then, vibration signals will generated although these do not...
A common electro-optic interface (EO) has been designed and tested with a new optic sensor decoding architecture. The EO module converts Wavelength Division Multiplexed (WDM) position, temperature pressure signals using the same circuitry. This uses combination of Digital Signal Processing (DSP) technology along sensing technology. approach results in circuitry for processing three dissimilar inputs. architecture was made possible by advancements two major areas, DSP growth advanced...
