Improvement of Response Properties of MR-Fluid Actuator by Torque Feedback Control

Magnetorheological (MR) fluids are substances that respond to an applied magnetic field with a change in their rheological behavior. Though they are functionally similar to electrorheological (ER) fluids, MR fluids exhibit much higher yield strengths for applied magnetic fields than ER fluids for applied electric fields. The devices using MR fluids have an ability to provide high-torque, low-in...

Fast-Response Electrostatic Actuator Based on Nano-Gap

The possibility of constructing new high-performance electrostatic fast actuators based on energy transformation in nanometer gaps is considered. The construction and the properties of the operation of such devices as well as their typical parameters are described. The drives are based on ferroelectrics with high values of dielectric permittivity (above 1000). They can be constructed using micr...

Fast fluid-attenuated inversion-recovery MR of intracranial infections.

PURPOSE To assess the usefulness of fast fluid-attenuated inversion-recovery (FLAIR) MR sequences in the diagnosis of intracranial infectious diseases. METHODS We compared fast FLAIR images with conventional spin-echo images (T1- and T2-weighted) obtained in 20 patients with infectious diseases (six with encephalitis, five with brain abscesses, three with meningitis, two with meningoencephali...

Influence of imaging parameters on high-intensity cerebrospinal fluid artifacts in fast-FLAIR MR imaging.

BACKGROUND AND PURPOSE High-intensity CSF artifacts at the basal cisterns on MR images are often seen when a fast fluid-attenuated inversion recovery (FLAIR) technique is used. We investigated the influences of four optional fast-FLAIR sequence parameters on the high-intensity CSF artifacts. METHODS A total of 377 patients (age range, 1 week to 91 years; mean 40.6 years; 186 female, 191 male)...
