Vibration controller for active vibration insulators and method for controlling vibrations for the same

The Journal of the Acoustical Society of America, 2006
A vibration controller includes a map controller, an adaptive controller, a set-up frequency judge/switcher, and an actuator. The map controller includes a data map storage for storing data on control signals determined in advance for a vibration insulator, and a signal generator for selecting one of the data, depending on a frequency of a cyclically ...

Vibrator, vibration unit, and vibrator control method

The Journal of the Acoustical Society of America, 2006
A vibrator has massaging balls supported by a treating unit that may be shifted along a subject portion for treatment, guided by guiding members. The treating unit is supported by a supporting structure with respect to the guiding members. A position or orientation altering mechanism is provided for altering the position of the treatment unit in a ...

Vibration and Vibration Control

1990
Vibration in machinery and structures is caused by the disturbing forces from, for example, reciprocating masses, unbalanced rotating masses, variable fluid pressure in hydraulic systems, turbulent wind loadings, wave action on structures, ground effects on vehicles, etc.

Vibration Controller of Marine Electromagnetic Vibrator

2009 International Conference on Measuring Technology and Mechatronics Automation, 2009
Marine electromagnetic vibrator is a non-explosive seismic source, for high resolution detection of marine seismic exploration ?which used sublevel sweep mode of marine electromagnetic vibrator. The vibration controller provides sublevel Chirp signal by marine geology condition. The Chirp signal was sent to exciter through power amplifier.

Design and control of a vibrating gyroscope

Proceedings of the 2004 American Control Conference, 2004
This work presents design and control of a vibrating gyroscope. The MEMS based device has been designed in the Pro-E environment and simulated in a finite element domain in order to approximate its dynamic characteristics with a lumped model. The device is a modified version of the existing MEMS gyroscope proposed in Yoichi, M, et al. (2000).

Mechanical Vibrations and Vibration Control

1994
In these lectures, an introduction is given into the basic concepts of the theory of active and passive vibration damping. First one degree of freedom systems are discussed with respect to the different solution techniques and with view to damping and isolation mechanisms.

Phase control in the vibrational qubit

The Journal of Chemical Physics, 2006
In order to use molecular vibrations for quantum information processing one should be able to shape infrared laser pulses so that they can play the role of accurate quantum gates and drive the required vibrational transitions. In this paper we studied theoretically how the relative phase of the optimized transitions affects accuracy of the quantum ...
