Flexible Organic LEDâ„¢s


Presented By: Ryan Evans



What the Flexible Organic Light Emitting Diode Consist of :

The Top Layer is the Cathode layer made of tungsten releases electrons when current is run through it.

Emissive Layer removes electrons from the cathode layer to make light.

Conductive layer is made from a type of organic plastic that removes the electron wholes

Then the Anode Layer that consist of removing and adding electron holes while the current is running through i ....etc

MAIN PURPOSE:


The hydraulic jack is a device, which is used to lift heavy loads by applying a lot of small force. It is based on the PASCAL LAW, which states that the pressure intensity is equally transmitted in all directions through a mass of liquid in res

ZENER DIODE TESTER

ABSTRACT


The testing of zener diodes requires a variable dc power supply. A typical test circuit can be constructed, as shown in figure 4-19. In this circuit, the variable power supply is used to adjust the input voltage to a suitable value for the zener diode being tested. With the zener diode connected no current will flow until the voltage across the diode is equal to the zener ....etc

ABSTRACT

A new operational mode for diode-clamped multilevel inverters termed quasi two-level operation is proposed. Such operation aims to avoid the imbalance problem of the dc-link capacitors for multilevel inverters with more than three levels and reduces the dc-link capacitance without introducing any significant voltage ripple at the dc-link nodes. The proposed operation can be generalized for any number of levels. The validity of the proposed multilevel inverter operational mo ....etc

FABRICATION OF PNEUMATIC FOOTSTEP LIFTING SYSTEM



Solenoid valve
A solenoid valve is an electromechanical valve for use with liquid or gas. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.
Solenoid valves are the most frequentl ....etc

ABSTRACT
Organic light emitting diode (OLED) display technology has been grabbing headlines in recent years. Now one form of OLED displays, LIGHT EMITTING POLYMER (LEP) technology is rapidly emerging as a serious candidate for next generation flat panel displays. LEP technology promises thin, light weight emissive displays with low drive voltage, low power consumption, high contrast, wide viewing angle, and fast switching times.
One of the main attractions of thi ....etc

INTRODUCTION
This project automatic electro-hydraulic jack for light vehicle garages has been developed to the needs of small and medium automobile garages.
In most of the garages the vehicles are lifted by using screw jack. This needs high man power and skilled labors.
In order to avoid all such disadvantages, this automatic electro-hydraulic Jack has been designed in such a way that it can be used to lift the vehicle very smoothly without any impact force. The operation is made be simple that even any person c ....etc
