It is known, for example, that the ion channels may be voltage-gated and also mechanically sensitive [48] and that an action potential generates an axoplasmic pressure wave in the intersticial fluid [43,44].
Therefore, the mechanism producing strong pressure waves and knock was investigated in this study by using a supercharged, optically accessible test engine to generate a wide range of knock intensities from weak to strong knock.
Investigations of the characteristics of pressure waves, which are generated, for example, by an electric discharge in a liquid, involve recording the total profile of the pressure wave at a given point in the volume of the liquid.
The leak detection market for oil & gas has been segmented based on technology into pressure wave technology, E-RTTM, fiber optic sensing cables, vapor sensing tubes, mass-volume balance method and others.
I estimated the velocity of the pressure wave at 4,460 ft.
The leak position can be calculated by comparing the arrival time of the pressure wave at the pipeline inlet and outlet pressure sensors.
This yields a propagating pressure wave that can be detected by sensitive ultrasound detectors.
The system invented at Sheffield tests pipes by transmitting a pressure wave along them that sends back a signal if it passes unexpected features, such as a leak or a crack in the pipe's surface.
The pressure wave actually snapped a couple of the machine guns in half.
In addition to these features, the SENSATION PLUS IAB catheter offers faster initiation of therapy, easier patient management and a crisp, clean arterial pressure wave form.
Clinicians have been asking for an LAB that combines all of the benefits of fiber optic technology, faster initiation of therapy, easier patient management and a crisp, clean arterial pressure wave form with increased hemodynamic support," said Deb Joseph, vice president, marketing and clinical services.
