Current internal combustion engine technology for road vehicles allows us to meet the existing and planned future standards for emission. However, the motion of a moving vehicle used in real operating conditions is frequent changes of the values of power in the powertrain. The analysis of the results of the road test through a measurement of parameters of engine in a passenger car proves, that ...

Gravitational force and acceleration measurement devises have been in continuous development with the objective to improve the method for realizations of the gravitational acceleration measurand accurately. The accuracy requirements from the field of metrology, geodesy, geophysics and mineral exploration led to these developments. In metrology, knowledge of gravitational acceleration is require...

Adaptive feedforward broadband vibration (or noise) compensation is currently used when a correlated measurement with the disturbance (an image of the disturbance) is available. Most of the active vibration control systems feature an internal ”positive” mechanical feedback between the compensation system and the reference source (a correlated measurement with the disturbance). Such systems have...

Acceleration, an important dynamic parameter, is used widely in researching on aircraft mechanical structure fatigue, shock and so on, as it is in proportion to force and load. Piezoelectric sensor is a kind of sensor that most widely used in measuring acceleration, is also called acceleration sensor or accelerometer, because its impulse response is excellent and is suitable for measuring shock...

Title: Acceleration sensors in abdominal wall position as a non-invasive approach to detect early breathing alterations induced by intolerance of increased airway resistance Authors: Thomas Breuer ([email protected]) Christian Bruells ([email protected]) Rolf Rossaint ([email protected]) Henning Steffen ([email protected]) Catherine Disselhorst-Klug ([email protected]...

In this study, we analyzed the swing motions of more experienced practitioner and new practitioner of iaido players by using tri-axial acceleration sensor and gyro sensor. Iaido is a modern Japanese martial art/sport. In this way, the acceleration and gyro sensor measurement enabled detailed motion information at the installation points to be displayed in a short time, thus making it possible t...

The potential efficacy of total body center of mass (COM) acceleration for feedback control of standing balance by functional neuromuscular stimulation (FNS) following spinal cord injury (SCI) was investigated. COM acceleration may be a viable alternative to conventional joint kinematics because of its rapid responsiveness, focal representation of COM dynamics, and ease of measurement. A comput...

In the research for the treatment of spinal cord injury (SCI), the evaluation of motor function in model rats must be as objective, noninvasive, and ethical as possible. The maximum speed and acceleration of a mouse measured using a SCANET system were previously reported to vary significantly according to severity of SCI. In the present study, the motor performance of SCI model rats was examine...
