Experimental Walking Assist Device With Body Weight Support System

This technology is designed for users who, though capable of walking on their own, would benefit from a reduction of load on their leg muscles and joints.An experimental walking assist device has been developed to help support body weight and reduce the load on the user’s legs while walking, going up and down stairs, and in a semi-crouching position. The device reduces the load on leg muscles and joints (in the hip, knees, and ankles) by supporting a portion of the person’s body weight. It features a simple structure consisting of seat, frame, and shoes, and the user can put it on by simply wearing the shoes and lifting the seat into position. Moreover, a mechanism that directs the assisting force toward the user’s center of gravity and the ability to control the assist force in concert with the movement of the legs make it possible for the device to provide natural assistance in various postures and motions.

Design Considerations for Battery Connectors

As medical devices become more portable and miniaturized, their power connections must evolve to meet these demands.The future of batteries, like that of so many medical devices they power, is clearly toward smaller, lighter, and more powerful models. Developing concurrently with these new battery designs are battery connectors. As battery connection devices evolve, they have to meet a number of challenges, including: rapid growth of designs; rugged construction; high-density packaging; manufacturing costs; and environmental concerns.

Improving the Vanadium Redox Battery

Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. New research indicates that modifying the battery's electrolyte solution significantly improves its performance - so much so that the upgraded battery could improve the electric grid's reliability and help connect more wind turbines and solar panels to the grid.

Capacitive Sensor Signal Conditioner

ZMDI (Dresden, Germany) has expanded its family of capacitive sensor signal conditioners (SSCs) with the addition of the wide-dynamic-range ZSSC3122 cLite device. With new design technology, the chip delivers 14-bit resolution and 0.25% full-scale-output accuracy. A built-in sleep mode lowers current consumption to <1uA for temperatures up to 85°C, making the ZSSC3122 ideal in low-power battery applications, as well as industrial and rugged environments.
