Like a lot of other young people, Suman Mulumudi has always had plenty of questions for his dad about his job. It just so happens that Mahesh Mulumudi is a cardiologist, so dinnertime conversations with his son almost always focused on his job's challenges.
Waterbury, Conn. and Harleysville, Pa. – Pittman Motors and Haydon Kerk Motion Solutions, business units of AMETEK Precision Motion Control, announces the launch of a new and improved Express websites that include a free shipping option. The Express websites allow visitors to evaluate and order a wide variety of precision motion components for 24-hour shipment anywhere in the world.
The Pittman Express and Haydon Kerk Express websites make available a variety of components for critical linear and rotary motion mechanisms used in applications such as medical equipment, laboratory instrumentation, industrial motion systems, high-end vending systems, or virtually any other system requiring precision motion control. Products available for immediate shipment include:
- Stepper motor linear actuators
- Precision leadscrew and anti-backlash nut assemblies
- DC brush motors
- DC gearmotors
- DC brushless motors
- Linear rail systems
Pittman Express offers a wide variety of DC brush motors, brushless motors, and gearmotors available in various frame sizes, continuous torque ratings, and voltages. Haydon Kerk Express has available a wide selection of linear motion products such as captive, non-captive, and external stepper motor linear actuators, stainless steel lead screws, anti-backlash nuts, and motorized/non-motorized linear rail systems.
While the Express product offering at both sites is a sampling of a much broader product line of motion components and systems, the list of online parts is extensive enough to help a product engineer quickly test a design concept. The online ordering system allows engineers to quickly obtain off-the-shelf precision motion products for concept testing, while evaluating the need for an application-specific customized solution.
The website includes all the information necessary for a design engineer to make an informed decision including downloadable performance data, outline drawings, detailed specification sheets, and CAD models. For more information, visit www.haydonkerkexpress.com or www.pittmanexpress.com

Pittsburgh - Alexander Star places a lapel pin on a table in his Eberly Hall office. Affixed to it is a microchip that he and his team have developed that may save joint implants before they’re ruined by infection. Even with his guidance, you have to squint to see the thing.
Star, an associate professor of chemistry in the Univ. of Pittsburgh’s Kenneth P. Dietrich School of Arts and Sciences, believes that this chip, which is engineered to detect pH levels in the body, will be able to alert doctors to encroaching bacterial infection, which causes acidosis, a drop in pH levels in nearby tissue.
The chip, festooned with tiny carbon nanotubes (engineered segments of carbon that are efficient electrical conductors) and treated with a proprietary polymer, reads pH levels and transmits the information to a radio frequency identification reader held by a doctor. The wirelessly powered chip can be attached to implants and can stay in the body long term.
One in 100 Americans have an artificial joint, Star says, “and bacterial infections are a common complication of the implant.” Infection can damage the body surrounding the implant, and bacterial films, resistant to antibiotics, can colonize the implant itself. To catch infection early without having to resort to invasive measures could lead to faster treatment. “This is a very attractive detection mechanism for monitoring the condition of the implant,” Star says. “It may alleviate the need for further surgical intervention.”
A paper on Star’s pH chip was recently published online in Scientific Reports.
Star has a history as a leader in this technology. He and his team have developed similar chip/nanotube sensors that can be affixed to a toothbrush to detect bad breath (the presence of hydrogen sulfide) and another that can identify the beginning of an asthma attack by measuring nitric oxide. Yet another Star-developed chip measures acetone in breath, an indicator of diabetes.
Star’s pH chip that detects infections was supported by a National Energy Technology Laboratory grant.
A close-up of the pH chip. So why does it say “Pitt” on there? Star explains, "You need some features on the chip for quality control – to make sure that the photolithography process was successful. So we decided to spell 'Pitt' rather than [make] a simple line. These gold lines are smaller in diameter than the fingers of our interdigitated electrodes (on the right), which we use for sensing. So if you can see [the] 'Pitt' letters, then all the electrode features are manufactured successfully."

The technology is being developed initially for amputees who suffer rubbing against their artificial limbs.
Dublin, Ireland – Covidien plc officials announced U.S. Food and Drug Administration 510(k) Clearance for the Kangaroo feeding tube with IRIS Technology. This first-of-its-kind camera-equipped disposable feeding tube is designed to enhance patient safety by providing visualization for a procedure that is currently blinded.
The Covidien Integrated Real-time Imaging System (IRIS) technology streams a real-time video back to the Kangaroo IRIS monitor, providing visual information that can aid clinicians in identifying key areas of a patient’s anatomy. The system also enables medical professionals to save images from the live stream and make notes associated with the image.
Prior to availability of the Kangaroo feeding tube with IRIS technology, feeding tube placement was often done blindly. The risk associated with blind placement is the misplacement of the feeding tube into the patient’s airway, which can potentially cause a punctured lung or even death. The Kangaroo feeding tube with IRIS technology now gives sight where medical professionals were previously blind.
“The Kangaroo feeding tube with IRIS technology is truly unique and was built with patient safety in mind,” said Jim Clemmer, president, Medical Supplies, Covidien. “Covidien is an industry leader in nutritional delivery and enteral feeding devices and products such as the Kangaroo feeding tube with IRIS technology are designed to help improve patient outcomes and set new expectations for medical device product safety and innovation around the world.”
In addition to FDA clearance in the U.S., the Kangaroo feeding tube with IRIS technology is approved for use in Europe, Japan, Canada, and Australia. The Kangaroo IRIS monitor is currently programmed with seven languages: English, Spanish, French, German, Italian, Portuguese, and Dutch.
