Electric gates alone, however solid and imposing they may be, cannot guarantee a completely secure environment electric locks, are often needed to boost the locking effectiveness of the gate motors. Electric gates are recommended to be used in combination with other security features to install a full security system .
The West Bank closure system is a series of obstacles including permanent and partially staffed checkpoints, concrete roadblocks and barriers, metal gates, earth mounds, tunnels, trenches, and an elaborate set of permit restrictions that controls and restricts Palestinian freedom of movement.
Some bar gates are automatic and powered; others are manually operated. Manual gates are sometimes hung in the manner of a normal gate (i.e. hinged horizontally). In some places, bar gates are installed across suburban streets as a traffic calming measure, preventing through traffic, while allowing authorised vehicles such as emergency services ...
As the function of a freight dock is to enclose deep water, such gates point inwards. A graving or dry dock, in contrast, excludes water, and so their gates point outwards. Hinged gates are relatively complicated, and so expensive, to construct. Large gates require powered machinery to operate them, machinery that must be provided for each set ...
A metal gate, in the context of a lateral metal–oxide–semiconductor (MOS) stack, is the gate electrode separated by an oxide from the transistor's channel – the gate material is made from a metal. In most MOS transistors since about the mid-1970s, the "M" for metal has been replaced by polysilicon, but the name remained.
The FDIC is an independent government agency charged with maintaining stability and public confidence in the U.S. financial system and providing insurance on consumer deposit accounts.
