One of the biggest improvements they made - was the ability to stop on a floor - then change direction. The first elevators had to travel the whole length of the building - either up or down - before they could reverse direction. This wasted time for people wanting to use them - as they had to wait for the elevator to return to their floor in the direction they wanted to co. Computerised controls now allow an elevator to (for example) travel up from the ground floor to - say - the 3rd floor - then go back down to the 2nd, and up again to the 5th.
There are quite a few metals that elevators are made out of. These elevators could be made out of stainless steel for example.
The improvements were made to PATA to allow for the programs to load faster. The improvements are made to make navigation easier as well.
Improvements were made to television to make tv experience better.
