artificial retina is developed for the disabled to people, so that they can retrieve their view. It was developed with the help of external camera (cameras) who worked as a stimulus from view of the brain through electrodes. The device has been used as a substitute for the cells in the retina of the eye. They have been formulated using large-scale integration third dimension, so that a person can receive the exact image of an object that is in front of them.

The artificial retinas function using thin-film transistors and capacitors. This dev ....etc

Seminar Report On SWITCH MODE POWER SUPPLY
ABSTRACT
The report is an overview of Switch Mode Power Supply abbreviated as SMPS. The purpose of report is to provide a general understanding of SMPS and its applications. There is a brief discussion of historical development of SMPS, followed by the common topologies of the same. The principle of operation is described which is almost same for all the topologies. Then the steady state analysis is discussed to have an insight of the operation under ideal and real conditions. The ....etc

Variable DC power supply is one of the projects that each student of the electronics should build. Build your own power supply is fun and use it throughout your building projects is the reward of your success. This project uses a transformer to reduce the incoming AC voltage to 12.5V AC.

This circuit is designed for 240VAC input voltage. If 110VAC is necessary, a power transformer 110 / 12.5 should be used. Buck of AC voltage is then rectified by a diode bridge. The rectified DC voltage is smoothed by means of an electrolytic capacitor 2 200uF ....etc

simple power supply resumption alarm pdf

The circuit of power resumption alarm shown here is very simple, where IC1 is wired in a special kind of mode. When power supply resumes, pin 2 of IC1 is grounded through C1 and pin 3 goes high. This makes reset pin 4 to go high for about 10 seconds. When the capacitor C1 charges to two-third of the supply voltage, output of IC1 goes low, grounding the reset pin 4 and thus disabling the entire circuit.

The alarm circuit is wired around a second timer IC, IC2. Here it is used as an astable multivibrator ....etc

Abstract
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed UPS sch ....etc
