1. A vane actuation system for a turbine engine, comprising: a unison ring for a vane stage of the turbine engine;a plurality of first links, each first link being coupled to a vane of the vane stage, and each first link being pivotably coupled to said unison ring;an other unison ring for an other v
1. A vane actuation system for a turbine engine, comprising: a unison ring for a vane stage of the turbine engine;a plurality of first links, each first link being coupled to a vane of the vane stage, and each first link being pivotably coupled to said unison ring;an other unison ring for an other vane stage of the turbine engine, wherein said unison ring and said other unison ring are not both disposed between said vane stage and said other vane stage;a plurality of second links, each second link being coupled to an other vane of the second vane stage, and each second link being pivotably coupled to said other unison ring;a third link having first and second ends, wherein the first and second ends of the third link are pivotably coupled to the unison ring and the other unison ring, respectively; anda fourth link pivotably coupled to said vane and said other vane,wherein the first, second, third and fourth links are configured to form a four-bar linkage; andwherein the four-bar linkage is configured to transmit rotation imparted to the unison ring from the unison ring to the other unison ring and/or to transmit rotation imparted to the other unison ring from the other unison ring to the unison ring. 2. The vane actuation system of claim 1, further comprising an actuator operable to supply an actuator force to at least one of said unison ring and said other unison ring. 3. The vane actuation system of claim 2, wherein said actuator is coupled to one of said unison ring and said other unison ring. 4. The vane actuation system of claim 1, wherein a rotation of said first link is operable to rotate the vane; and wherein a rotation of said second link is operable to rotate the other vane. 5. The vane actuation system of claim 1, wherein said fourth link is stationary. 6. The vane actuation system of claim 5, wherein said fourth link is a vane case of said turbine engine. 7. The vane actuation system of claim 6, wherein the vane case is a compressor vane case. 8. The vane actuation system of claim 1, wherein said third link is pivotably coupled to said unison ring at a same circumferential location as one of said first links. 9. The vane actuation system of claim 1, wherein said third link is pivotably coupled to said other unison ring at a same circumferential location as one of said second links. 10. The vane actuation system of claim 1, further comprising a plurality of third links pivotably coupled to each of said unison ring and said other unison ring. 11. A turbine engine, comprising: at least one of a fan section, a compressor section and a turbine section;a vane stage, said vane stage being at least one of a fan stage, a compressor stage and a turbine stage;an other vane stage, said other vane stage being at least one of an other fan stage, an other compressor stage and an other turbine stage; anda vane actuation system, said vane actuation system including: a unison ring for said vane stage;a plurality of first links, each first link being coupled to a vane of said vane stage, and each first link being pivotably coupled to said unison ring;an other unison ring for said other vane stage, wherein said unison ring and said other unison ring are not both disposed between said vane stage and said other vane stage;a plurality of second links, each second link being coupled to an other vane of the other vane stage, and each second link being pivotably coupled to said other unison ring;a third link having first and second ends, wherein the first and second ends of the third link are pivotably coupled to the unison ring and to the other unison ring, respectively; anda fourth link pivotably coupled to a vane of said vane stage and a vane of said other vane stage,wherein the first, second, third and fourth links are configured to form a four-bar linkage; andwherein the four-bar linkage is configured to transmit rotation imparted to the unison ring from the unison ring to the other unison ring and/or to transmit rotation imparted to the other unison ring from the other unison ring to the unison ring. 12. The turbine engine of claim 11, further comprising an actuator operable to supply an actuator force to at least one of said unison ring and said other unison ring. 13. The turbine engine of claim 12, wherein said actuator is coupled to one of said unison ring and said other unison ring. 14. The turbine engine of claim 11, wherein a rotation of said first link is operable to rotate the vane; and wherein a rotation of said second link is operable to rotate the other vane. 15. The turbine engine of claim 11, wherein said fourth link is stationary. 16. The turbine engine of claim 15, said turbine engine including a vane case for said at least one of said fan section, said compressor section and said turbine section, wherein said vane case serves as said fourth link. 17. The turbine engine of claim 16, wherein the vane case is a compressor vane case. 18. The turbine engine of claim 11, wherein said third link is pivotably coupled to said unison ring at a same circumferential location as one of said first links. 19. The turbine engine of claim 11, wherein said third link is pivotably coupled to said other unison ring at a same circumferential location as one of said second links. 20. The turbine engine of claim 11, further comprising a plurality of third links pivotably coupled to each of said unison ring and said other unison ring. 21. A turbine engine, comprising: at least one of a fan section, a compressor section and a turbine section;a vane stage, said vane stage being at least one of a fan stage, a compressor stage and a turbine stage;a unison ring for said vane stage;an other vane stage, said other vane stage being at least one of an other fan stage, an other compressor stage and an other turbine stage;an other unison ring for said other vane stage, wherein said unison ring and said other unison ring are not both disposed between said vane stage and said other vane stage; anda vane actuation system, said vane actuation system including: means for coupling the rotation of the vanes of said vane stage with the rotation of the vanes of said other vane stage,wherein said means for coupling includes a link having first and second ends pivotably connected to the unison ring and to the other unison ring, respectively.
