There are three different major types of modal tests depending on the type of excitation manner: Forced Vibration Test (FVT), Ambient Vibration Test (AVT) and Free Vibration Test.

The vibration test is to detect an asymmetry in the vestibular system at high frequencies.

Ocular nystagmus is diagnosed when the patient is sitting and lying down and after different kinds of stimulation (head shaking test, vibration test, head impulse test).

There are three different major types of modal tests depending on the type of excitation manner: Forced Vibration Test (FVT), Ambient Vibration Test (AVT) and Free Vibration Test.

A test signal is injected into one or more of the inputs of the MEMS vibratory type inertial sensor, where the test signal produces a test signal component at one or more of the MEMS vibratory type inertial sensor outputs.

The detection electrode (82C) is formed by containing a vibration node of lateral primary vibration mode, which node is a vibration node of bent secondary vibration mode.

An actuator, which is operatively attached to the vibratory element, moves the vibratory element in a motion.

Disclosed herein is a vibratory moving apparatus having a vibratory unit.

The vibration detector is used to detect the vibratory response of the bone to the vibratory stimulus and produces a signal representative of the vibratory response.

A plurality of speaker/sensors (100-1 - 100-n) is provided to apply vibratory pressure to a test subject.

The front-side vibration isolation member (61) and the rear-side vibration isolation member (62) have the same structure.

The vibration test is to detect an asymmetry in the vestibular system at high frequencies.
