Bike Seat post adjuster

My idea is to design a seat post that is adjustable vertically using pneumatics or with gas pressure. This is compared to a office chair that is adjustable by simply lifting on handle and adjust chair height as needed. In addition to that feature the pneumatic pressure would allow some comfort in terms of a spring action much like a bike seat shock for bumps on the road. Secondly, the seat adjuster would not allow any rotation so that the bike seat is always point forward. The important features of this design that the bike user could quickly adjust the seat for different heights and have shock comfort. For Mountain biker, this is very useful to adjust your seat height for different difficulty of down hill or up hill riding.
