Supplier Stories for the Week of March 15

Here’s what was new in the world of medical device suppliers during the week of March 15.

  • Performance Motion Devices Inc.

    Performance Motion Devices Inc. (PMD) now offers Juno Velocity Control ICs for advanced velocity control of 3-phase brushless DC and DC brush motors with features such as PI (proportional, integral) velocity loop control, programmable velocity estimation, dual biquad filtering, shunt regulation, deadband filtering, FOC (field-oriented control), and more. They are suitable for applications such as spindle control, centrifuges, peristaltic pumps, laboratory automation, packaging automation, and more.

    “Juno ICs offer our customers high-performance microstepping or stepper servo motor control at a low cost,” explained Chuck Lewin, Founder and CEO of PMD, in a news release. “These ICs are also an ideal way to upgrade your existing pulse & direction controller for stepper servo operation, or for starting your next machine design project from scratch.”

    Available in a 64-pin TQFP package measuring 12x12 mm, these ICs feature high/low switching amplifier control signals, leg current sensing, 6-step (using Hall Sensors) Sinusoidal commutation modes, and point-to-point asynchronous serial, multi-drop asynchronous serial, SPI, or CANbus communication modes.

  • Jeff Nelson, president of Nelson Laboratories LLC, issued an update after the March 18 earthquake in Salt Lake City, UT, and shared a COVID-19 continuity plan.

    After the magnitude 5.7 earthquake as well as several smaller aftershocks, Nelson's buildings sustained only minor cosmetic damage (some drywall cracks and a broken pipe), which has since been repaired). Operations were not disrupted, and testing continues as the company focuses on its mission of "Safeguarding Global Health," Nelson reported.

    Nelson Labs also provided a "Coronavirus Continuity Plan Update" in which:

    • Each laboratory location is employing a rotating shift schedule with divided teams to minimize the risk of an infection disrupting an entire service line.
    • All possible non-laboratory staff have shifted to work-at-home status to increase social distancing and to minimize the risk of infection. Key on-site personnel will be maintained to perform testing.
    • The Salt Lake City location cafeteria has closed to increase social distancing and to minimize infection risk in compliance with Utah state expectations.
    • The company is coordinating closely with suppliers to ensure consistent supply flow to sustain testing.

    The continuity plan is constantly being re-evaluated by Nelson's team, and the company is working to minimize the risks associated with this outbreak without negative impacts or disruptions for customers.
