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

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

ADVANCED ELECTRIC GENERATOR & CONTROL FOR
HIGH SPEED MICRO/MINI TURBINE BASED POWER SYSTEMS

INTRODUCTION

High-speed micro-turbines and mini-turbines play a significant role in the Distributed
Power Systems that provide dependable electric power close to the user. Several high-speed
turbo-generators manufactured by various corporations are now available in the 30 kW to 90 kW
range. These systems operate at speeds from 50000 RPM to 120000 RPM. The generator is
directly coupled to the turbine shaft. This ob ....etc

Abstract:
We developed an electrostatic micro power generator for low frequency energy harvesting applications. This micro power generator consists of a new vibration structure and new electret electrode. The advantage of this micro power generator is the high power generation structure of both the controlled gap
between electrodes and long-range moving at low frequency. This generator shows 40+W of power output at very low frequency vibration (2Hz, 0.4G).

Micro Turbine Generator Program

Abstract
A number of micro turbines generators have recently
been announced as currently commercially available for
sale to customers, such as end users, utilities, and energy
service providers.
Manufacturers and others are reporting certain
performance capabilities of the turbines; however, no
consistent third-party independent testing as been done to
confirm or discredit such performance claims. The
purpose of this project is to provide such an independent,
third party ....etc

For today s electronics devices the main limiting factor is the battery there is not just enough energy for a given size and weight. As a result of the research in this field have yielded micropower generators recently. They offer higher energy storage densities. The main types are micro engine, which is the shrinked form of an internal combustion engine, thermo electric generator which generates electricity based on seeback effect, microreformers which reform hydrogen and advanced mini fuel cells which generates energy by oxidation reactio ....etc

Introduction
Microturbine generator systems are considered as distributed energy resources which are interfaced with the electric power distribution system. They are most suitable for small to medium-sized commercial and industrial loads. The microturbine provides input mechanical energy for the generator system, which is converted by the generator to electrical energy. The generator nominal frequency is usually in the range of 1.4-4 kHz. This frequency is converted to the supply frequency of 50 Hz by a ....etc

abstract for automatic timetable generator abstract

Most colleges have a number of different courses and each course has a number of subjects. Now there are limited faculties, each faculty teaching more than one subjects. So now the time table needed to schedule the faculty at provided time slots in such a way that their timings do not overlap and the time table schedule makes best use of all faculty subject demands. We use a genetic algorithm for this purpose. In our Timetable Generation algorithm we propose to utilize a timetable object. Thi ....etc
