Computerized Kymograph for Muscle Contraction Measurement Using Ultrasonic Distance Sensor
نویسنده
چکیده
Kymograph is a device to record the magnitude of physiological variables, such as: muscle contraction. However, we observe some lacks of the conventional kymographs, such as: result’s visualisation and accuracy. Hence, we propose a computerized-kymograph which can automatically measure, record, and display graphical data of muscle contraction on the computer by using ultrasonic distance sensor. We develop hardware and software systems to support computerized kymograph and then test our device with live frog. The result shows that the device works well by displaying better visualization than the conventional kymograph. Keywords—kymograph; computerized; distance sensor

Uncertainty Measurement for Ultrasonic Sensor Fusion Using Generalized Aggregated Uncertainty Measure 1
In this paper, target differentiation based on pattern of data which are obtained by a set of two ultrasonic sensors is considered. A neural network based target classifier is applied to these data to categorize the data of each sensor. Then the results are fused together by Dempster–Shafer theory (DST) and Dezert–Smarandache theory (DSmT) to make final decision. The Generalized Aggregated Unce...
متن کاملCaffeine Alters Skeletal Muscle Contraction by Opening of Calcium Ion Channels
The aim of this study was to investigate the effect of caffeine on the amplitude and rate of skeletal muscle contraction using frog sciatic nerve-gastrocnemius muscle model. Caffeine is a xanthine alkaloid whose use is widely unregulated. It is taken as a central nervous system stimulant in various foods and drinks. The effect of caffeine on skeletal muscle contraction and a possible elucidatio...

Background: The transverse abdominis (TrA) muscle is one of the most important muscles that contribute to the stability of the lumbar spine. Strengthening of trunk muscles that have a significant role in trunk stability is very important in the field of professional sport, sport medicine and rehabilitation of patient with low back pain (LBP). Identifying the exercises that can improve the stren...

متن کاملCross-Correlation by Single-bit Signal Processing for Ultrasonic Distance Measurement
Ultrasonic distance measurement using the pulse-echo method is based on the determination of the time of flight of ultrasonic waves. The pulse-compression technique, in which the cross-correlation function of a detected ultrasonic wave and a transmitted ultrasonic wave is obtained, is the conventional method used for improving the resolution of distance measurement. However, the calculation of ...
