Abstract

According to one embodiment, an apparatus for loading vibration is provided. The apparatus for loading vibration has a contacting unit, a first vibration unit, a storage unit and a control unit. The contacting unit is capable of coming into contact with a biological body which pulsates or beats in a contact state of a first contact condition. The first vibration unit provides a self-excited vibration to the biological body through the contacting unit. The storage unit stores a second contact condition which synchronizes the self-excited vibration with the pulses or the beats. The control unit controls the contact state of the contacting unit so as to make the first contact condition become closer to the second contact condition.

First claim

What is claimed is:

1. An apparatus for loading vibration, comprising:
a contact adjuster capable of coming into contact with a biological body which pulsates or beats in a contact state of a first contact condition;
a first vibrator which is a non-linear vibrator and is configured to provide a self-excited vibration to the biological body through the contact adjuster;
a storage device configured to store a second contact condition which synchronizes the pulses or the beats with the self-excited vibration; and
a controller configured to control the contact adjuster to adjust the contact state so as to make the first contact condition become closer to the second contact condition, wherein
the controller includes
a calculating unit which obtains an amplitude and/or phase of the pulsates or beats and the amplitude and/or phase of the self-excited vibration and calculates an amplitude and/or phase variation amount;
a determining unit which determines whether or not the amplitude and/or phase variation amount is equal to or less than a predetermined threshold value; and
a controlling unit which controls the contact adjuster to change the first contact condition so as to decrease the amplitude and/or phase variation amount when the amplitude and/or phase difference is not equal to or less than the predetermined threshold value, and
a difference Δω between a frequency of the first vibrator and a frequency of the pulsates or beats satisfies the following equation in order to cause an entrainment where A is an amplitude of the pulses or the beats and ε is an interaction parameter showing the first contact condition for adjusting the intensity of the pulses or the beats, and
−ε/(2 A )<Δω<ε/(2 A ).

2. The apparatus according to claim 1 , further comprising a first measuring instrument configured to measure amplitude of the pulses or the beats, wherein the second contact condition is a condition where the pulses or the beats are synchronized with the self-excited vibration in phase, and the controller controls the contact state so as to increase the amplitude measured by the first measuring instrument.

3. The apparatus according to claim 2 , further comprising a second measuring instrument configured to measure a cycle of the self-excited vibration, wherein the first measuring instrument further measures a cycle of the pulses or the beats, the controller uses the cycle of the pulses or the beats measured by the first measuring instrument and the cycle of the self-excited vibration measured by the second measuring instrument to calculate a phase difference between the self-excited vibration and the pulses or the beats, and the controller controls the contact state so as to decrease an amount of the phase difference to synchronize the pulses or beats with the self-excited vibration.

4. The apparatus according to claim 2 , further comprising a second vibrator configured to provide a minute vibration to the biological body through the contact adjuster.
