The circuit uses an op-amp IC CA3140 (IC2) as voltage comparator and timer NE555 (IC3) in monostable configuration for alarm. Voltage comparator IC2 senses the voltage level cation. When the brake is applied‚ the green LED blinks and the piezobuzzer beeps for around one second if the brake system is

ULTRA-SONIC DISTANCE METER. Introduction to Ultrasonic Distance Meter The project Ultrasonic Distance Meter is a very interesting and useful project for many industrial applications. In this project we have used the ultrasonic waves to measure the distance in between two points. The basic principal is based on the speed of ultrasonic waves in open air. We have used a microcontroller AT89S51 to transmit and receive ultrasonic waves through 40 KHz ultrasonic receiver and transmitters. By measuring

CHAPTER 1 INTRODUCTION 1.1 History A forklift (also called a lift truck‚ a high/low‚ a stacker-truck‚ trailer loader‚ side loader or a fork hoist) is a powered industrial truck used to lift and transport materials. The modern forklift was developed in the 1920s by various companies including the transmission manufacturing company Clark and the hoist company Yale & Towne Manufacturing. The forklift has since become an indispensable piece of equipment in manufacturing and warehousing operations

CHAPTER 1 INTRODUCTION 1.1 GENERAL Nowadays‚ there is a demand of power supply. As an electrical engineer‚ it is necessary to design system with low cost‚ reduced losses and higher efficiency. This paper proposes nine-switch converter with single controller‚ rather than using 12 switches for operation of drives separately. In electrical vehicle drives mostly AC motors are used. It is because of its well known advantages like simplicity‚ reliability‚ lack of mechanical commutator

MICROCONTROLLER BASED ANESTHESIA INJECTOR ABSTRACT In the hospitals when any major operation is performed‚ the patient must be in anesthetize condition. If the operation lasts for a long time‚ say for suppose for 4 or 5 hours‚ complete dose of anesthesia cannot be administered in a single stroke. It may lead to the patient’s death. If lower amount of anesthesia is administered‚ the patient may wakeup at the middle of the operation. To avoid this‚ the anesthetist

EE 2403 SPECIAL ELECTRICAL MACHINES 2 MARKS UNIT-I - SYNCHRONOUS RELUCTANCE MOTOR 1. What is synchronous reluctance motor? A reluctance motor is a type of synchronous electric motor which induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. 2. Define the characteristics of synchronous reluctance motor. The synchronous reluctance motor is not self starting without the squirrel cage. During run up it behaves as an induction
