arrives. Hence‚ if the train is late due to certain reasons‚then gate remain closed for a long time causing traffic near the gates. By employing the automatic railway gate control at the level crossing the arrival of the train is detected by the sensor placed near to the gate. Hence‚ the time for which it is closed is less compared to the manually operated gates and also reduces the human labour. This type of gates can be employed in an unmanned level crossing where the chances of accidents are

ii) Remote control For ensuring the safety of the user this system provides an additional type of controlling other than BRI and it is Remote control‚ which means robot is controlled by an external person. The switching of the control system is optional which is done by a mode selector. Simplified block diagram of remote control is shown in Fig.5. Atmel microcontroller is used in the design process of remote control. These types of microcontroller provide justified technology‚ an affluent efficiency

Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By

property of quartz is that it is possible to select the temperature dependence of the material by the cut angle and the wave propagation direction. With proper selection‚ the first-order temperature effect can be minimized. An acoustic wave temperature sensor may be designed by maximizing this effect.Other materials that have commercial potential include gallium arsenide (GaAs)‚ silicon carbide (SiC)‚ langasite (LGS)‚ zinc oxide (ZnO)‚ aluminum nitride (AlN)‚ lead zirconium titanate (PZT)‚ and poly vinylidene

from a tank. This is possible by using two sensors. We put one near the bottom and one near the top‚ as shown in the picture below •Here‚ we want the fill motor to pump lubricating oil into the tank until the high level sensor turns on. At that point we want to turn off the motor until the level falls below the low level sensor. Then we should turn on the fill motor and repeat the process.

In order to avoid bringing a lot of dust‚ concrete mixer must also be equipped with air filter and automatically remove dust in the air by using vibration theory. In addition‚ the use of sensors can also protect the silo bin and avoid excessive pressure. (2) Water measurement Water firstly is weighed by measuring

compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer‚ a force sensor‚ and a Ti-Nspire Calculator. The Ti-Nspire Calculator was connected to the force sensor in order to track and create data that would be shown in graphs on the calculator. Because we had to compare the collision of the cart with the force sensor with and without the plunger‚ it would force
