COMPENSATION OF NONLINEAR DISTORTION IN INERTIAL DEVICES

2018Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO), 2018
In any communication system the main problem block is a power amplifier since when it operates in high efficiency mode makes nonlinear distortion in the amplified signal. This paper presents a method for compensation distortions in nonlinear inertial devices (NID).

Damping characteristic analysis of MEMS inertial devices

SPIE Proceedings, 2005
The damping effects of MEMS inertial devices like micro accelerometers is studied. The damping analysis governing equation, the Reynolds equation, is the fundamental equation in this work. For small amplitude sinusoidal motions, which are governed by the linearized form of the Reynolds equation, both damping and compressibility effects are modeled ...

Silicon on insulator inertial MEMS device processing

SPIE Proceedings, 2006
During the 1980's and 1990's the methods used to manufacture inertial MEMS devices could be divided into two groups; bulk and surface micromachining. Institutions which developed high precision inertial MEMS devices usually employed bulk micromachining processes. This was done to fabricate devices with large proof masses and stiff beams which result in

A smart device inertial-sensing method for gait analysis

Journal of Biomechanics, 2014
The purpose of this study was to establish and cross-validate a method for analyzing gait patterns determined by the center of mass (COM) through inertial sensors embedded in smart devices. The method employed an extended Kalman filter in conjunction with a quaternion rotation matrix approach to transform accelerations from the object onto the global ...

Vibration Control with Nonlinear Rotating Inertial Mass Device

IABSE Reports, 2015
<p>The authors have been carrying out numerical studies on the effect of a passive nonlinear absorber containing a rotating inertial mass (N-RIM). In this paper, the performance of this proposed absorber system when used for the base isolation of a building against strong earthquakes is presented. The N-RIM system consists of a strongly nonlinear

Active Vibration Isolation Devices with Inertial Servo Actuators

Cosmic Research, 2018
The use of active vibration isolation devices (AVIDs) in aerospace engineering is subject to the following restrictions. First, the volume for installing additional devices is always limited in instrument racks and compartments. Secondly, in many cases, it is impossible to add supports for servo actuators for fundamental or design considerations.

Engineering issues of gridded inertial electrostatic confinement devices

17th IEEE/NPSS Symposium Fusion Engineering (Cat. No.97CH36131), 2002
Gridded inertial electrostatic confinement (IEC) systems have shown the successful formation of ion microchannels, with very good ion focusing properties. Nevertheless, major concerns exist about the integrity of the grid due to plasma heating and neutron irradiation. In this study, a hollow tungsten grid, actively cooled by a pressurized water circuit,
