A stair assistance device for use with a handrail, the device comprising a sleeve engageable with and slideable relative to the handrail, and a brake element to hinder or prevent sliding movement of the sleeve, wherein, when the sleeve is engaged with a handrail, the brake element is resiliently biased towards the handrail, to hinder or prevent movement of the sleeve when the device is not in use.

System and method for user intent recognition

A method of operating an exoskeleton system that includes determining a first state estimate for a current classification program being implemented by the exoskeleton system; determining a second state estimate for a reference classification program; determining that a difference between the first and second state estimate is greater than a classification program replacement threshold; generating an updated classification program; and replacing the current classification program with the updated classification program based at least in part on the determining that the difference between the first and second state estimates is greater than the classification program replacement threshold.

Soft inflatable exosuit for knee rehabilitation

A soft-inflatable exosuit for knee rehabilitation is fabricated in two different beam-like structures (I and O cross-section actuators) and mechanically characterized for their torque performance in knee-extension assistance. The fabrication procedure of both types of actuators is presented as well as their integration into a light-weight, low-cost and body-conforming interface. To detect the activation duration of the device during the gait cycle, a soft-silicone insole with embedded force-sensitive resistors (FSRs) is used. In evaluation studies, the soft inflatable exosuit device is tested for its ability to reduce muscle activity during the swing phase of the knee. Using sEMG (surface electromyography) sensors, the rectus femoris muscle group of a healthy individual is recorded while walking on a treadmill at a constant speed, with and without the soft device.

Method apparatus systems and mechanisms for boosting and stimulation of weaker body parts powered by harvested energy from other parts of the body
20220054345 · 2022-02-24 · ·

This invention relates to methods, apparatuses, systems for boosting and stimulating the motion of weaker body parts of a person or animal by harvesting the power or strength of stronger body parts. It describes mechanisms for harvesting, storage and release of energy from one part of the body to another part of the body. A preferred embodiment of the present invention describes harvesting through mechanical means, storage through mechanical means and release through mechanical means to help harness energy from one strong part of the body to boost the muscular power of a weaker part of the body.

HYBRID TERRAIN- ADAPTIVE LOWER-EXTREMITY SYSTEMS
20230165693 · 2023-06-01 ·

Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.
