Raymond A Lia: Borescope or endoscope with fluid dynamic muscle. Welch Allyn, Wall and Roehrig, January 3, 1989: US04794912 (169 worldwide citation)


A fluid dynamic muscle contracts when air or hydraulic pressure is applied to it. The muscle has a long elastomeric bladder covered by a long tubular braid of flexible but inextensible fibers or filaments. When the bladder is inflated the braid is forced to expand laterally, which shortens it axiall ...
