Abstract: A four leg, lower extremity, robotic exoskeleton system is provided for medically assistive motion in gait, sit to stand (STS) and step climbing activities. The system has four articulated robotic legs, including two exoskeleton legs and two auto-pole legs, which are connected to a torso frame, controlled by a motion controller and a user interfaces, and that interacts with an assistive stationary robotic chair, or a wheelchair, for storage, dressing, STS and rest. The STS motion, in the stationary chair and the wheelchair, may be done with a single axis linear actuator, which maintains a back seat tip parallel to the ground for safety and comfort. Links of the exoskeleton and auto-pole legs are actuated by a linear or rotary actuators with their synchronized motion controlled by the motion controller, for safety, comfort and cost performance optimization depending on the medical needs.

Abstract: An applicator assembly for applying a cord to a tire-building surface that rotates during tire construction. The applicator assembly includes an applicator member to apply the cord. A first rotary device rotates the applicator member about a first axis that is transverse to the surface. A first translation device moves the applicator member in a first linear path relative to the surface. The applicator member may include a roller and/or a resilient member. A second rotary device may rotate the applicator member and the first rotary device around a second axis substantially perpendicular to the first axis. A second translation device may move the applicator member, the first rotary device, the second rotary device, and the first translation device. A system for applying the cord to a core member may further include a spindle to rotate the core member about the axis of rotation.
