On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc

ABSRTACT

The delayed resonator, as a tunable active vibration absorber with an emphasis on the design features. This technique uses a control that has a time-delayed feedback of the absorber mass displacement. The substance of this process is in that the absorber completely removes oscillations from the harmonically excited primary structure. Seminal features of this method are the excitation frequency range can vary over a semi-infinite interval, and the absorber can be tuned in real ....etc

Laser Micro-Patterning by Means of Optical Fibers with Micro-grinded Lens End Faces



Introduction

Nano-patterning of polymer surface has found a wide range of applications including biotechnology, where holes in the size of hundreds nm can influence the growth and differentiation of relatively large living cells . Instead of the e-beam patterning technique used in the Ref. 1, we ap-plied direct writing by laser-light. In our previous papers , we have demonstrated that th ....etc

Resonator
A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonance frequencies, with greater amplitude than at others
It oscillates at specific frequencies because its dimensions are an integral multiple of the wavelength or half-wavelength at those frequencies
Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal
In physics and engineering the quality ....etc

H-Shaped Dielectric Resonator Antenna for UWB application



INTRODUCTION
The extremely wide spectrum of 3.1 to 10.6 GHz with 15 bands of bandwidth greater than 500 MHz and power limit less than -41.3 dBm/MHz announced by FCC for Ultra wide band. The release of this Spectrum has rapidly increased the research in UWB technology for communications, radar imaging, and localization applications . Radio systems based on UWB technology offer opportunities for transmission of high data r ....etc

Dielectric Resonator
1.Introduction
A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field which redu ....etc

ABSTRACT

Balanced doubly suspended structure has been used earlier for very precise high Q resonators. But here we have used the unbalanced half section which is sputter deposited with a magnetic film. The central axis acts like a torsion wire of about a micron width and thickness. The outer arm deflects downwards about the torsion ....etc
