AUTO MUTE FOR AUDIO DECK (Automatically Mute Your Audio System when you receive a call) Muting car’s audio deck‚ while talking on cell phone is an important yet difficult task. This project is designed to solve the problem. A sensitive IR transmitter and receiver pair is designed and fixed to a cell phone holder. Always the cell phone should be placed in the holder. The transmitter unit continuously transmits IR rays. These IR rays are interrupted by the cell phone. Whenever the cell phone

Dear Editor: Through your papers I want to draw the attention of concerned authorities towards the worst condition of roads in Karachi. Almost all roads in Karachi are destroyed. This situation of roads is very dangerous for drivers. By this condition of roads loss of expensive vehicles and many horrible accidents are seen. Here no doubt roads are made but it also doomed very soon and the reason behind this is the use of inferior quality of material. Citizens of Karachi pay the vehicle tax

Differentiate among the current account‚ balance of trade and balance of payments. Current account is the net profits that a country gain from its export and imports of goods and services‚ earning from foreign investment also the included the profits from transfer of payments. Current account is important because it includes all international merchandise trade and service accounts‚ that is‚ accounts for the value of all merchandise and services imported and exported and all receipts and payments

Measuring the Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper

Mechanical power input can be controlled by a control system known as Mechanical Governor. It operates as a valve on the turbine inlet that can be closed to restrict the flow of water (and therefore the power) going into the turbine to match the current electrical loading. But this method of frequency control is expensive for Micro-hydro system and also its response is slow. So this method is not adopted for micro-hydro system. So‚ for the control of the frequency in a micro-hydro system an Electronic
