This document describes an automatic wiper system for vehicles presented by J. Vijay Kumar. It discusses the need for automating wiper systems to increase safety and reduce driver workload. The key components of the system include a water sensor, battery, wiper motor, and relay. The sensor detects rain on the windshield and sends a signal to activate the wiper motor automatically without driver input. The system aims to provide a low-cost solution for automatic wiper control in automobiles and other applications.
The aim is to design and develop a control system based an electronically controlled automotive rain operated motor
The sensor is used to detect the rain or water flow
Automatic rain sensing wiper is a new era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation.

Embedded systems, especially in-vehicle embedded systems, are ubiquitously related to our everyday life. The development of embedded systems greatly facilitates the comfort of people’s life, changes our view of things, and has a significant impact on society
Today, a typical automobile on the road has computer controlled electronic systems, and the most commonly used embedded systems in a vehicle include Airbags, anti-lock braking system, black box, adaptive cruise control, drive by wire, satellite radio, telematics, emission control, traction control, automatic parking, in-vehicle entertainment systems, night vision, heads up display, back up collision sensors, navigational systems, tyre pressure monitor, climate control, etc
It is all about Traction Control and its importance for car safety. The slide presentation will help you to know about the types of traction and the roles of traction control system to optimize the grip and stability of a car on the road while running. Traction definitely causes the friction on tire as well as in braking system of a car.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. INTRODUCTION
The Rain Tracker automotive rain sensor, senses rain or snow hitting the
windshield, and automatically runs the wipers at the right speed.
we don't have to take our hands off the wheel, or constantly adjust the speed of
the wipers as road conditions change
A rain sensor or rain switch is a switching device activated by rainfall.
In this the sensor projects infrared light into the windshield at a 45-degree
angle.
If the glass is dry, than most of this light is reflected back into the sensor by the
front of the windshield.
If water droplets are on the glass, than it reflect the light in different
direction…the wetter the glass, the less light makes it back into the sensor.
4. The electronics and software in the sensor turn on the wipers when the
amount of light reflected onto the sensor.
software sets the speed of the wipers based on how fast the moisture
builds up between wipes. It can operate the wipers at any speed.
5. AUTOMATION
The Automatic rain operated wiper system is a fully automation project.
This is an area of automation where it is broadly defined as replacement
of manual effort by mechanical power in all degrees of automation.
The operation remains an essential part of the system although with
changing demands on physical input as the degree of mechanization is
increased.
Degrees of automation are of two types:
Full automation.
Semi automation.
In semi automation a combination of manual effort and mechanical
power is required whereas in full automation human participation is
very negligible.
6. NEED FORAUTOMATION
Automation can be achieved through the computers, hydraulics, pneumatics
and robotics etc. of these sources, pneumatics form an attractive medium for
low cost automation.
Pneumatics is a branch of engineering that makes use of gas or pressurized air.
Pneumatic systems used in industry are commonly powered by compressed
air or compressed inert gases
Automation plays an important role in automobile.
7. REASON FORAUTOMATION
To achieve high safety .
To reduce man power.
To increase the efficiency of the vehicle .
To reduce the work load.
To reduce the vehicle accident .
To reduce the fatigue of workers.
To high responsibility .
Less Maintenance cost.
12. WORKING
The battery supplies the power to the sensor as well as rain operated motor.
Wiper motor is automatically ON during the time of rainfall.
The senor is fixed in the vehicle glass.
The conductive (Touch) sensor is used in this project.
It senses the rainfall and giving control signal to the control unit.
The control unit activates the wiper motor automatically.
This operation is called “Automatic rain operated wiper”.

14. ADVANTAGES
Low cost automation project.
Free from wear adjustment.
Less power consumption .
Operating Principle is very easy.
Installation is simplified very much.
To avoid other burnable interactions viz.… (Diaphragm) is not used.
It is possible to operate Manually/automatically by proving ON/OFF switch.
Sensor cost is very low due to conductive sensor.
15. DISADVANTAGES
In order to avoid false detection of rain, it requires rain sensors to take decision
after few minutes.
The rain sensor based system functions when water falls on the sensor directly.
The cost of overall system increases as additional components are needed along
with rain sensors.
16. APPLICATIONS
It is used in four wheeler .
It is used in aircraft.
It is used in train .
It is used in six wheeler.
In marine applications.
