References p. 24 I. Introduction What is LED light? With a view to creating a better quality of light and saving energy LED light has entered the light industry. Full form of LED is light emitting diode. The concept of LED is pretty simple. Like every other diodes‚ LED is made of semiconductor filled with impurities from Group IIIA and GROUP VA elements‚ creating a p-n junction. As electricity flows from the p part to the n part‚ holes from the p part meet the electrons from the

8051 Project: Automatic Lighting and Visitor Counter Andrew Herzog Richard Baker December 13‚ 2007 CMPET 211 Executive Summary The objective of the project was to create a circuit with an 8051 microcontroller that sensed when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. Discussion To complete the project several smaller circuits were needed to be designed and constructed. The project

History of Pulse Oximetry Before the Pulse-Oximeter the only way to measure SpO2 was by using a painful arterial blood gas which took a minimum of 20-30 minutes to view the result. In 1974 Takuo Aoyagi a Niigata University student disclosed his first Pulse-Oximeter for the use of pilots in World War 2. He set about searching for a non-invasive way of monitoring arterial blood oxygen saturation. Nellcor’s pulse oximeter was put on the market in 1983 and this used his theory developed in 1974. By

ABSTRACT In the present world of the human mind always need information of interest to control systems of his/her choice. In the age of electronic systems it is important to control and acquire information from everywhere. Although many methods to remotely control systems have been devised‚ the methods have the problems. Hence the need for special devices and software came to control the system. This suggests a method for control using the DTMF tone generated when the user pushes mobile phone

PROPERTIES AND CHARACTERISTICS OF COMMON INDUSTRIAL MATERIALS “LCD‚ LED & CRT” LCD COMPOSITION A liquid-crystal display (LCD) is a flat panel display‚ electronic visual display‚ or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden‚ such as preset words‚ digits‚ and 7-segment displays
