VELOX Processing technology employs advanced rapid sampling and signal processing techniques to output data at high speed with minimal phase lag. VELOX enables system designers to replace legacy analog Inertial Systems and Rate Sensors with affordable, high speed digital inertial systems and sensors.
This induces an inertia-related phase lag between the ossicles and the surrounding bone, i.e., to motion of the stapes footplate in the oval window, leading to inner ear fluid displacements and pressure differences across the basilar membrane, and subsequently its displacement and a traveling wave.
If this phase lag results in the two rays' waves being in phase (meaning the waves' troughs and crests are aligned), the color corresponding to that wavelength will be visible.
This can be designed to respond to the pressure variation generated by the compressor, with a phase lag and amplitude determined by the system dynamics.
On the other hand, from the thermal wave phase lag, the thermal diffusivity measurement can be also obtained by the measurement of the thermal wavelength which is defined as [9]
As shown in case e, by comparing curves e-1 and e-2, it can be found that the phase lag of the temperature wave in the gas phase is about 20% along the x-axis, the time after reaching the highest temperature is delayed, and the amplitude of the temperature wave is also reduced by 30%.
The phase lag of evoked SSVEP due to communication delays is depicted in Figure 4.
Corresponding to the gradually decreasing roll-off frequencies, the phase of the spectra demonstrates a significant phase lag from the middle to the basal bead and then the stapes, indicating a slow wave propagating backward in the cochlea.

In this study, an angular oscillation frequency of the electromechanical oscillation mode with the least damping ratio is selected to calculate the phase lag that is compensated by the PODC.
(2010) further utilized the Fourier method to investigate the amplitude and phase lag along the thickness direction (surface, middle, and core layer).
Results showed that, despite the use of in-phase coordination modes in both able-bodied and patient groups, the amount of phase lag between adjacent segments in a whole gait cycle was not similar.
