PCT No. PCT/GB92/00984 Sec. 371 Date Jan. 19, 1994 Sec. 102(e) Date Jan. 19, 1994 PCT Filed Jun. 1, 1992 PCT Pub. No. WO93/00666 PCT Pub. Date Jan. 7, 1993.An actuator assembly comprising a pair of interconnected extensible actuators defining two sides of a triangle structure, and a linkage constrained to move with the actuators such that differences in extension of the actuators cause a change in position of the linkage. Changes in position of the linkage are detected to enable relative actuator extensions to be monitored.
