As the days get shorter and fall gives way to winter, Jim Bradley knows it’s time to reach for his trusty socket set and get to work. The annual Bikes for Kids charity is nearly upon him, and Bradley, a 32 year veteran of Parker Chomerics, has been instrumental in spearheading the fundraiser for the past five years.
Bikes for Kids solicits generous donations from Chomerics employees and their families and builds and delivers bicycles to the Toys for Tots, a program run by the United States Marine Corps Reserve which distributes toys to less fortunate children, allowing them to share in the magic of the holidays.
“Oftentimes, these are first-time bicycle riders who have dreamed of their first bike. There’s nothing better than seeing the face of a child who has been given the freedom to ride,” explains Bradley.
And this year, there’s truly something else to celebrate. Right on the heels of his retirement at the end of the year, Bradley and the Parker Chomerics Bikes for Kids program have surpassed 1,000 built and donated bikes over the past five years.
“It is truly an astounding accomplishment and we’re so happy to be able to give a child the thrill of receiving a brand new bike,” said David Hill, global general manager of Parker Chomerics. “I cannot thank Jim enough for his 32 years at Parker Chomerics and his tireless efforts managing Bikes for Kids. He’s going to be a hard guy to replace,” he added.
For Bradley’s sake, he’s excited to be able to spend more time with his grown children and grandchildren in retirement. “Something tells me I might not be done with Bikes for Kids in the future,” he hinted.
Every Parker location is focused on local community support and fundraising activities. In addition to donations, many employees also volunteer their time; dedicating countless hours in support of organizations that appeal to a personal connection.
Company sponsored fundraising drives include everything from holiday gifts, coats and backpack collections; to funds for education, the arts, medical research, community support organizations, and much more.

Not long ago in hospitals and other critical care facilities, you were greeted with a large, ominous warning sign the moment you walked through the entrance doors to refrain from cell phone use due to possible medical equipment malfunction or interruption.
Today, patients and visitors are free to use mobile phones and devices without fear of interfering with medical equipment, but there’s still a long way to go to reduce electromagnetic emissions and electromagnetic compatibility (EMI/EMC) issues in medical devices.
Medical devices require complex analysis of the EMI/EMC regulations used for medical equipment and system certification. There are many new aspects that need to be addressed since medical devices are no longer used in just a hospital setting. With the increase of wearable medical tech, patients can theoretically be anywhere in the world. Therefore, EMI/EMC compliance testing needs to address the location of “end use” such as in the home healthcare environment and transportation considerations – trains, planes and automobiles.
The primary EMI/EMC standard for medical electrical equipment and systems is IEC 60601-1-2. Developed by the International Electrotechnical Commission, this global standard applies to the basic safety and essential performance of medical equipment and systems in the presence of electromagnetic disturbances, and to electromagnetic disturbances emitted by equipment and systems.
It also recognizes that RF wireless radio communications equipment (mobile phones, Wi-Fi and biotelemetry) can no longer be prohibited from the patient environment and medical equipment and systems.
However, the standard falls short of defining EMI/EMC test requirements for special environments and points to manufacturers addressing special environments in the risk assessment.
Remember, the difference between emissions and immunity tests are that the emissions requirement is concerned with the amount of electromagnetic energy emitted from your device, while the immunity requirement is concerned with how susceptible your device is to electromagnetic energy existing in the location of end use. This includes energy being emitted from surrounding devices.
The world of medical devices is dramatically changing how medical electrical equipment and systems are being used in various environments. Many different EMI/EMC standards need to be considered to address all environments of intended use.
Parker Chomerics Test Services, in association with Parker Chomerics Applications Engineering can assist in determining what standards should be applied to your medical electrical equipment and systems and help ensure compliance to the requirements. Our extensive experience in solving EMI/EMC test failures will result in manufacturable solutions which will reduce your time to market.

You are working on a new design and want to incorporate the sealing system directly – in 3D including a design space proposal? In Parker Prädifa´s CAD library, 3D step files are available for you to download.
CAD models as 3D Step files for numerous standard products are available on our product pages at www.parker.com/praedifa (or via the “CAD Library” quick link).
This makes it possible for design engineers to import Parker Prädifa seals and the matching design spaces as models directly into CAD designs for a full representation of the system. The CAD bill of materials then automatically includes the seal’s part number. This creates greater transparency and allows the parts to be traced in the system.
As a special benefit the sketch of the design space proposed by Parker Prädifa for the selected profile already exists in the model. This precludes the risk of mistakes in dimensioning the design space and further facilitates the concept design of the total system for the design engineer.

5. Design Decisions Relating to EMC Shielding
When approaching the problem of electromagnetic compatibility (EMC), design engineers often consider it to be a secondary issue that can be dealt with once the device is working and, after all, it can be dealt with by putting a metal box around it! But that places mechanical engineers in a tough position as they deal with constraints such as weight, cost, performance and corrosion. Discover our best design tips to help with EMI shielding DURING the design stage! Read now.
4. Best Conductive Plastics: Five Things to Look For
Can electrically conductive plastics really replace traditional metal electronics enclosures? The answer is a resounding yes! There are very effective electrically conductive plastics available today that provide excellent electromechanical properties that help shield portable electronics from the electromagnetic interference (EMI) noise that is proliferating our daily life.
Smart phones, Bluetooth, Wi-Fi, radio, even your television are all susceptible to EMI. Discover the key points you may want to consider when evaluating electrically conductive plastics for your application. Read now.
3. The Difference Between Thermal Conductivity and Thermal Impedance
While not technically a blog about EMI shielding, thermal interface materials and EMI shielding generally go hand in hand. Thermal Interface Materials (TIMs) are useful for thermal management in electronic components, as they enhance heat transfer from a heat-generating component to a heat dissipater, or heat sink.
Across the industry, manufacturers often publish thermal conductivity in units of Watts / meter-Kelvin as well as thermal impedance in units of °C – inches2 / Watt on their datasheets. So, what is the difference between these two, and how should you consider them when selecting a TIM? Read on to find out!
2. Five Ways to Maximize Performance of Electric Vehicle Batteries
Electric vehicles are developing fast in line with growing demand. However, only by selecting proven, reliable, high-quality products for the effective thermal management and EMI shielding of batteries, is it possible to maximize performance.

1. The Art of Spraying Electrically Conductive Paints
An oldie of a post – but clearly still a goodie! Electrically conductive coatings for plastic enclosure electromagnetic shielding are growing in popularity as concerns over weight increase for a variety of EMI applications in the military, aerospace, automotive, telecom, medical, and semiconductor marketplaces. However, conductive paints cannot be applied in the same way conventional paints are. Many first attempts do not go as well as planned. Learn more about how proper preparation and practice will make you successful in your application.
