Gearmotors: Achieving the Perfect Motor & Gearbox Match

July 24, 2012 2:59 pm | by Seth Hulst and Loren Kamstra | Groschopp, Inc. | Comments

For electrical and mechanical design engineers in the process of developing applications, choosing a gearmotor can be a tricky and arduous process. Can motors and gearboxes be purchased separately and then matched for an application? Is it better to specify a pre-engineered gearmotor? What are the differences? By following the two gearmotor selection methods readers will receive a checklist of considerations to determine which process would be the most helpful and steps to complete the gearmotor selection process. There are many factors to consider when choosing a gearmotor.

Designing a Wound Dressing to Manage Burns

July 18, 2012 1:51 pm | by Steve Bishop, Wayne Bonnefin, and Lucy Ballamy | Convatec | Comments

It is estimated that one million burn injuries occur annually in the United States, resulting in 45,000 hospitalizations. The hands are involved with a large number of burn injuries, and partial thickness burns (PTBs) are among the most frequently-occurring types. A PTB is marked by the destruction of the epidermal cell layers of the skin, extending into, but not through, the dermis.

Micro-machining technology, simply stated, is the utilization of semiconductor manufacturing equipment in such a way that it creates micro-mechanical systems that serve a specific purpose. MEDER’s objective was to develop a micro-miniature hermetically sealed reed switch that is able to function exactly like the larger, standard hermetically sealed reed switch.

New Patch-Based Wearable Sensor Combines Advanced Skin Adhesives and Sensor Technologies

July 17, 2012 2:50 pm | by Deepak Prakash | Vancive Medical Technologies™ | Comments

Advances in adhesives, materials, software and sensor technologies are spurring development of a new generation of wearable sensors and monitors for medical and health management applications. A notable example is a patch-based wearable sensor that adheres comfortably to the user’s skin and continuously gathers physiological and lifestyle information, with certain versions that will include vital signs and other indicators for up to seven days. The patch-based wearable sensor represents a major advancement in personal monitoring device design, functionality and wear time.

Yes, it is Brain Surgery – So Precision is Everything

July 17, 2012 2:23 pm | by Lynn Manning | Comments

The patient lies wide awake in the operating room (OR), the top of his draped head bared to the neurosurgeon. A second doctor stands at the patient’s side, lifts the man’s arm, and flexes it gently. The hand and wrist are stiff, with a visible tremor. The surgeon makes a slight adjustment to brain-penetrating electrodes mounted through a starburst-shaped plastic fixture fastened to the man’s skull. “How about now?” the surgeon asks. The arm is moved again, this time naturally, smoothly, without shaking. “That’s it,” says the patient, nodding his head with relief.

Large Diameter, Low Speed Fans Work Year-Round for Manufacturing Spaces

July 17, 2012 2:04 pm | by Erin Holaday Ziegler | Comments

Many manufacturers face challenges with energy costs, employee comfort and product integrity year-round.
