Thermal Management Solutions for Medical Applications

Thermoelectric Assemblies (TEAs) offer precise temperature control for applications with tight space constraints and low weight requirements. Thermal management of medical electronic devices and systems is now more challenging. Power densities continue to increase while product form factors continue to shrink. Simple thermal management solutions, such as passive cooling (adding a fan and heat sink), are no longer typically viable to meet required performance and reliability specifications. In today’s complex medical operating environment, Thermo electric Assemblies (TEAs) are necessary to provide precise temperature control via cooling and heating in a variety of modular platforms.

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.

GigE-Vision®-Compliant Receivers for the Networked Operating Room

A new type of system offers ultra-low-latency image transmission and low jitter for surgical environments.When vision system integrators are designing systems for hospital operating rooms, they have a number of technologies to choose from. The video interfacing technology with which the system will transmit imaging data to PCs or other system elements has traditionally been limited to point-to-point connections. However, as medical diagnostics and image-guided surgery grow in sophistication and demand, the need for a networked video architecture in the operating room also grows.

Power-Assist Control Interface for Wheelchairs

This technology monitors input and effort, and instantly adapts the device to real-world conditions.A computer-controlled, programmable control interface allows safe, intuitive manual control for motorized wheelchairs that operate in variable terrain. The key feature of this technology is its proprietary computer program that enables an operator to manage a load as if it were light and on a smooth level surface, no matter what the real-world load or grade is. Operation is completely intuitive and does not require manipulation of throttle and/or brakes.
