USA is a melting pot of various cultures. Several languages other than English is spoken / written all over in big cities. This situation is not just in USA, it exists in most developed nations.
Regardless of how people think of ‘fast food’ is here to stay.
Millions of people have ‘fast food’ everyday. Going through the drive-thru is as normal as breathing.
Anybody who has used the drive-thru knows how hard it can get sometimes to

Spacecraft docking is a mission necessity in space technology. Docking allows for materials transfer: people, cargo, supplies etc. This requirement is exhibited in numerous on-orbit and historical satellites.
This paper introduces an androgynous docking mechanism with two moving parts: two small sleeves made of a Shape Memory Alloy (SMA) material are used to accomplish a reliable and stiff mechanical connection with an automatically sealed fluid connection.
The proposed docking interface (Figure 1) has been invented for

FCHTMC is an engine that works from any heat source.
In the home and business applications Solar, Geothermal and CNG energy are all possibly available.
As the device is specifically designed to waste as little energy as possible, it is more efficient than current generation systems by more than 50%. The device utilizes lightweight materials that do not absorb heat energy within. These same materials are fully dense and nearly as hard as diamond. Through simple

Coupling is a device, which is used to connect two different shafts and transmit power from one source to another and also provide flexibility against misalignment. At present we are using attraction based magnetic coupling, which has limited efficiency, limited torque transmitting, induce E.M.F generation at high speed, slippage problem & they fail at high speed. So to avoid this we have design repulsion based magnetic coupling. This type of coupling will be helpful to
