Correlation between motion frequency and motion total amplitude index varied from region to region.

运动节律与运动总振幅指数的相关性因部位不同而异。

When a number of certain static images, such as geometric figures, for example, interchange with a specified frequency, it creates something like a motion picture effect.

当一组特定的静态图像，例如几何图形，以指定的频率切换，便会产生某种动态图片的效果。

For fixed damping and fixed excited frequency the motion of the beam under small amplitude of force is periodic, but becomes chaotic through period doubling bifurcation with increase of the force.

对固定的参数激励频率和阻尼，当参数激励幅值较小时梁的运动是周期的，但大幅值激励会使运动通过倍周期分岔变为混沌。

High resolution is achieved by measuring motion rather than radio frequency signals as wifi does, and is based on where and how the person moves through an environment over time.

BBC: Technology that works behind closed doors

Unlike traditional keyboards that place your hands in a rigid position, the Engage Keyboard features a patented motion system that studies your typing frequency and makes subtle, comfortable adjustments periodically so your hands and wrists are never in a fixed position while you work.
