High lift rescue vehicles save human life even at great height.
The fire brigades have high lift rescue vehicles to save people in dangerous situations at great height. They thus secure the second escape route for trapped persons as required in building laws.
High lift rescue vehicles are special fire engines used to rescue persons, animals and goods at great height. For this purpose a turntable ladder is used. A "turntable ladder" is the movable part of a high lift rescue vehicle which is located above the truck chassis.

On 26 June 1974 ...
... the cashier Sharon Buchanan scanned a ten pack of chewing gum according to the UPC standard (Universal Product Code) in a supermarket in Troy, Ohio.
The code had, however, already been developed and patented at the end of the 40s by two students of the Drexel Institute of Technology in Philadelphia: Joseph Woodland and Bernard Silver.

Trailing Suction Hopper Dredger?
Is it a hopping dredger or is it named after its inventor?
No, it is a swimming dredger used to excavate easily removable sediments such as sand. The self-driven cargo hold suction dredger removes solid material from the bottom of waters through trailing heads and pumps it into the hopper tanks in the ship through a suction pipe. Among others, the hopper dredger is used to deepen ship channels.
The biggest hopper dredger so far is the Vasco da Gama, built in 2000. It was also used for the construction of the Palm Islands of Dubai.
