mirror page link an interoperability standard seminar abstract report

MirrorLink is a device interoperability standard that offers integration between a smartphone and a car's infotainment system. MirrorLink transforms smartphones into automotive application platforms where apps are hosted and run on the smartphone while drivers and passengers interact with them through the steering wheel controls, dashboard buttons and touch screens of their car's In-Vehicle Infotainment (IVI) system.MirrorLink utilizes a set of well-established, non-propriet ....etc

A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....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

Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
Conditions for stabilized voltage source biasing
Emitter resistance, RE, is needed.
Base voltage source will have finite resistance, RB.
needs to be much larger than RB.
Small RB - relative to RS - will attenuate input signal.
Larger RE permits larger RB, but results in lower gain.
Gain = -RC/RE for RE >> re.
Split RE with bypassing increases gain.
Requires large bypass cap ....etc

For the past six years, Digital Light Processing technology from Texas Instruments has made significant inroads in the projection display market. With products enabling the world?s smallest data and video projectors, HDTV?s, and digital cinema, DLP technology is extremely powerful and flexible. With success of the DMD as a spatial light modulator for projector applications, dozens of new applications are now being enabled by general- use DMD products that are recently available to developers. The same light switching speed and ?on-off? (contras ....etc

design and fabrication of air operated mirror cutting machine

abstract

the aim of the project is to design and fabricate the air operated mirror cutting machine. cutter is a common tool used in various cutting shape for a variety purposes. in this project, a glass cutter is provided which can form, using a wheel, a uniform crack in glass even when a projection or an earlier-formed scribe line is present on the glass. when the wheel is moved on the glass, a fracture layer is formed causing a rib mark to be formed below the fracture layer a ....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
