The suitport concept integrated lessons learned from prior studies and upgraded the user interface to use pneumatic actuation. Pneumatic actuation of the suitport and other minor upgrades were successful in improving the donning and doffing process for most users. The tether system used an external waist bearing hooked to four retractable cables that were anchored in a square pattern to form a work area. These features allowed the test subject to conduct geological work without frequent re-clipping, nor unintended entanglement in the tethers.application/pdfengPresentation
