Patent ID: 8597573

Claim:
A fluid flow characteristic regulator, comprising: a) a fluid flow path; b) a control fluid flow path adjacent said fluid flow path; c) a flexible barrier located between said fluid flow path and said control fluid flow path, wherein the flexible barrier has a first barrier surface defining a portion of the fluid flow path and a second barrier surface defining a portion of the control flow path; d) a fluid flow variation sensor positioned within the fluid flow characteristic regulator to sense movement of said flexible barrier in response to a fluid flow in said fluid flow path, wherein the fluid flow variation sensor generates a fluid flow variation signal based upon movement of the flexible barrier; e) a fluid flow variation signal analyzer in communication with the fluid flow sensor, wherein the fluid flow variation signal analyzer generates control fluid adjustment values in response to said fluid flow variation signal; f) a control fluid delivery adjustment element in communication with the fluid flow variation signal analyzer, wherein the control fluid delivery adjustment element converts said control fluid adjustment values to corresponding control fluid delivery adjustment values; and g) a control fluid controller in communication with the control fluid delivery adjustment element, wherein the control fluid controller adjusts control fluid characteristics of a control fluid in said control fluid path based on said control fluid deliver adjustment values.
