  • Publication number: 20240033158
    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.

  • Publication number: 20230268189
    Abstract: Methods and apparatuses for precise trimming of silicon-containing materials are provided. Methods involve oxidizing silicon-containing materials and thermally removing the oxidized silicon-containing materials at particular temperatures for a self-limiting etch process. Methods also involve a surface reaction limited process using a halogen source and modulated temperature and exposure duration to etch small amounts of silicon-containing materials. Apparatuses are capable of flowing multiple oxidizers at particular temperature ranges to precisely etch substrates.
