Motion Control Advancements Ease Medical Procedures

Whether performing an intricate surgery, positioning a patient, or taking a tissue sample, today’s biomedical devices are taking advantage of advanced motion control devices to ensure accurate control and movement in biomedical applications. Robots are making it possible to perform surgical procedures not only with higher precision than before, but in less time and with less pain and suffering for the patient. Moreover, improvements in the design and packaging of motors and other control components are making it possible to shrink biomedical devices and make it easier to perform procedures in tight, confined spaces.

Mass Flow Controllers Ensure Astronauts Have Medical Fluids On Demand

Quantim Coriolis mass flow controller Brooks Instrument Hatfield, PA 215-362-3527 www.brooksinstrument.comTransporting medical fluids that are manufactured on Earth into space is expensive and logistically challenging, so researchers at NASA’s Johnson Space Center sought a way to manufacture medical fluids in space. The Quantim Coriolis mass flow controllers from Brooks Instrument were chosen by NASA contractor ZIN Technologies for measuring water flow through a purification system to a standard IV bag that was prefilled with salt crystals and a magnetic lab stirrer. The Quantim devices are making their way into space to ensure that astronauts have medical fluids on demand for emergency needs.

Rotary Motors Customized for Telescope Spectrometer

SQUIGGLE® custom rotary piezoelectric motors New Scale Technologies Victor, NY 585-924-4450 www.newscaletech.comThe Wide-Field Multi Object Spectrometer (WFMOS) is a ground-based astronomical instrument that is scheduled to be commissioned on the Subaru Telescope on Mauna Kea, Hawaii in 2013. The WFMOS, along with corrective optics, will be mounted in place of the secondary mirror of the telescope. An array of NASA Jet Propulsion Laboratory’s Cobra fiber positioners will feed light from a 1.5-degree field of the sky to a visible spectrometer, for red shift observations of 2,400 cosmological targets simultaneously. The light will be transferred to the spectrograph using 2,400 f/2.4 fibers with 107 μm cores.

High-Speed Cameras Assist in Crash Sled Testing

The Kettering University Crash Safety Center (Flint, MI) conducts vehicle subsystem tests using a pneumatic deceleration sled. The research and testing includes frontal, rear, or side impact occupant protection systems containing airbags, pretensioners, and/or child safety seats. The sled system can carry up to a 2,000-pound payload to a speed up to 42 miles per hour, and reach peak decelerations over 70 Gs. Access to high-quality imagery and dependable on-board and off-board high-speed digital video is as vital to the success of the data collection as is the anthropomorphic test devices (ATDs, also known as “crash dummies”) and their instrumentation (Figure 1).

Omron Controls and Drives Improve Animals’ Joint Health

Ferno Aquatic Therapy, Wilmington, OH, designs and manufactures canine and equine underwater treadmill equipment used by veterinarians to provide aquatic therapy, rehabilitation, and conditioning for both dogs and horses. Designed specifically for canine rehabilitation, the Ferno Aqua Paws Plus Under water Treadmill System allows dogs to begin the rehabilitation process earlier than normal. Using the buoyancy, resistance and heat properties of water, the Aqua Paws unit creates a low-impact treadmill workout that helps the animal to increase muscle strength and endurance, providing the foundation for a quicker transition to land-based therapy.
