摘要:
A carotid pulse measurement device provided for measuring carotid pulse of a user's neck includes a band, an artery-pressing air cell, an inflating/deflating device, and a pressure detection unit. The band functions to surround the user's neck. The air cell is arranged in the band and is fluidly connected to the inflating/deflating device for selectively inflating/deflating the air cell. The pressure detection unit detects variation of pressure inside the air cell. To use the measurement device, the band is put around the user's neck with the air cell positioned exactly corresponding to the carotid artery of the neck so that the pressure detection device detects the pressure variation and generates a digital pulse signal, which is employed to calculate arteriosclerosis index of the user for evaluation the degree of arteriosclerosis of the user.
摘要:
A liquid transportation device includes a working board, a working liquid, a liquid channel and a cover board, wherein the liquid channel is formed on a top surface of the working board, the covering board is fully covered the liquid channel, the liquid channel composed of a material substantially tending to the liquid, and the covering board is composed of a material substantially phobic to the liquid. The working liquid flows within the liquid channel in guidance of the deviation of surface tension between the liquid channel to the working liquid, and the covering board to the working liquid, so that the working liquid is transported within the liquid channel without any external power.
摘要:
An ultrasonic imaging technique for differentiating the distribution of scatterers within a tissue comprises a correcting and an imaging procedure. The correcting procedure includes steps of obtaining ultrasonic backscattered signals from a standard phantom, compensating and demodulating the signals into an envelope image, calculating the parameter m and m, selecting a window to calculate parameter mw in each location of the envelope image and mw, if mw≠ m then increase the size of the window to repeat the steps above, and when mw= m, it is the optimal size of the window. The imaging procedure includes steps of obtaining ultrasonic backscattered signals from a target tissue, compensating and demodulating the signals into an envelope image, calculating mw in each location to form a mw matrix, and presenting the matrix by utilizing pseudocolors.
