Airlock
An airlock is a device which permits the passage of people and objects between a pressure vessel and its surroundings while minimizing the change of pressure in the vessel and loss of air from it. The lock consists of a small chamber with two airtight doors in series which do not open simultaneously.
An airlock may be used for passage between environments of different gases rather than different pressures, to minimize or prevent the gases from mixing.
An airlock may also be used underwater to allow passage between an air environment in a pressure vessel and the water environment outside, in which case the airlock can contain air or water. This is called a floodable airlock or an underwater airlock, and is used to prevent water from entering a submersible vessel or an underwater habitat.
Use
Before opening either door, the air pressure of the airlock—the space between the doors—is equalized with that of the environment beyond the next door to open. This is analogous to a waterway lock: a section of waterway with two watertight gates, in which the water level is varied to match the water level on either side.
Airlock (parachute)
A parachute airlock (simply airlock in context) is a safety mechanism built into some parachute models which resist it losing its shape while open. It uses a ram air structure to stiffen each section of the outer edge.
The design was pioneered by parachute inventor Brian Germain following a near-fatal ram-air wing collapse in 1994. Germain made a full recovery to personally test many of the airlock prototype parachutes, often in extreme conditions. Specific parachute designs utilizing the Airlock technology include the following: Jedei, Sweptwing, Genesis, Warlock, (AirTimeDesigns.com) Vengeance, (PerformanceDesigns.com) Samurai, Lotus, Sensei R1 (BigAirSportz.com).
While the airlock approach to canopy design has generated an enthusiastic user base, the design also has its problems. For example, a ram-air parachute designed with airlocks will not deflate quickly upon landing on a windy day. This may result in dragging a parachutist across the ground. Parachute packers have also noted that these canopies take longer to pack due to the extra time it takes to squeeze the air out. However, proponents prefer the safety advantages of a stable canopy in flight over inconveniences on the ground.
Airlock (band)
Airlock is a Belgium based trip hop musical group formed November 1997 in Brussels notable for their ambient music on several popular TV series: CSI: Crime Scene Investigation and CSI: Miami. The band members were Renaud Charlier, Ernst W. Meinrath and Pierre Mussche.

The Other Way
by: AirlockI am small but I can see
I am weak but I can feel
You do what you want to do
You say what you want to say
And then when the times are bad
You're down upon your knees
Is it too much to empathize
Just realize
And he will break through you
And he will break through you
To go to the other end
He will follow you
Who's telling me
Who's telling me
Why tell me
To look the other way
Who's telling me
Who's telling me
Why tell me
To look the other way
We seem to talk far too much
And I find myself asking where has all the love gone
You know so well how to hate
You know so well how to complicate
Who's telling me
Who's telling me
Why tell me
To look the other way
Who's telling me
Who's telling me
Why tell me
To look the other way
And he will break through you
And he will break through you
To go to the other end
He will follow you
Who's telling me
Who's telling me
Why tell me
To look the other way
Who's telling me
Who's telling me
Why tell me
To look the other way
I am small but I can see
I am weak but I can feel
I am small but I can see
I am weak but I can feel
I am small but I can see
