Closed System Technology Drives the Trend Toward Safer Dispensing of High-Purity Chemicals

In dozens of industries and in millions of applications around the world, dangerous chemicals are transferred from their original shipping containers into smaller jugs or buckets, or applied to other end-use processes. Historically, the predominant dispensing method in many of these applications has been through an open system where the liquid is poured out of the container. In many industries using high-purity chemicals, a popular dispensing method is a semi-closed system that pumps the liquid out of a drum or container. In these systems, a dip-tube draws chemicals from vertically oriented containers using an attachable hand or electric pump. While a step in the right direction, the semi-closed dispensing system requires a dip-tube that needs to be removed and re-inserted each time a new drum is used, exposing the end user to drips, leaks, and fumes during transfer. The primary drawback of all open and semi-closed systems is that they needlessly expose the user, equipment, and the environment to potentially hazardous chemicals and vapors.

Controlling Robotics Precisely With Haptic Technology

Robots are capable of very precise motion, but must be guided with precision in order to fulfill their potential. Consider the task of guiding a robotic surgeon’s arm to suture a wound or insert a catheter. A human surgeon, with all his or her knowledge and experience, is required to practice where to probe, cut, or sew before he or she can develop the necessary skills to make a clean suture with the right degree of tension at the right depth or an incision of the right depth. In contrast, a robotic surgeon’s arm can move more consistently and accurately than that of the best human surgeon.

Advances in Magnetic Bearings

In this age of environmental consciousness, OEMs around the world are competing to build better, safer, and greener machines. In striving toward such lofty goals, many industries are rediscovering a fundamental principle — magnetics. Magnetic bearings improve reliability, reduce friction, minimize vibration, and offer advanced health monitoring and diagnostics — all without the disadvantages of lubricants.

Reducing Electromagnetic Interference in Motion Systems

EMI (Electromagnetic Interference) comes in different forms, frequencies, and levels. Electronic equipment has different categories for both emissions and susceptibility. Under normal circumstances, elimination is not possible so reduction to acceptable levels is what can be reasonably achieved. Coupling factors, rise time, emissions, and susceptibility are phrases that must be understood with confidence.

Controlling Devices Using the Ear as an Output Source

This method creates a hands-free way of controlling devices such as medical equipment, wheelchairs, computers, and cell phones.Current methods of device control include joysticks, which involve using one or both hands, external microphones that are cumbersome and pick up ambient noise, and external arrays that are also cumbersome and can restrict a user’s movement. Additionally, the external microphone and array options do not provide a high level of accuracy in certain situations.
