Risk Assessment for Power Supplies to Comply with IEC 60601-1 3rd Edition
Posted in Manufacturing & Prototyping, Custom & Contract Manufacturing, Monitoring & Testing, FDA Compliance/Regulatory Affairs, Electronics, Power Supplies, Power Management, Medical, Features, MDB on Tuesday, 01 January 2013
For medical device OEMs seeking compliance to the 3rd Edition of IEC 60601-1 for their power supplies, what is quite clear by now are the regional dates for enforcement, the required risk management at the medical electrical equipment or system level, the new definitions of Means of Operator Protection (MOOP) and Means of Patient Protection (MOPP), and other differences as compared to the 2nd Edition. What is not clear is how to address these new definitions and requirements. Rather than simply redesigning and resubmitting for 3rd Edition certification, questionnaires and flowcharts that map out the requirements at the device or system level help to minimize the evaluation and redesign at the power supply level. By having the medical device OEM and power supply vendor answer the questionnaire concurrently, deficiencies from the equipment or power supply can be quickly assessed in order to satisfy the requirement.

Wireless Power Solutions for Medical Technology
Posted in Custom & Contract Manufacturing, Electronics, Electronic Components, Power Management, Medical, Features, MDB on Thursday, 01 November 2012
In today’s medical technology field, having a reliable and stable power source is a critical requirement for safe operation. Wireless power provides a unique advantage in that a device can now be completely sealed, thus allowing a device to be safe, robust, and simpler to maintain. And with improvements in wireless power delivery, new developments allow up to 500 watts of power.

The last few years have seen the development of larger, higher power, higher luminescence light-emitting diode (LED) chips. Prior to this, LEDs were typically 0.020" x 0.020", came in various colors and were used primarily as optical indicators. This new breed of LEDs come in various colors, including white and UV, are typically 0.040" x 0.040" and are designed to provide high intensity light for illumination applications. Individually packaged versions of these LEDs are being used in arrays and clusters to replace standard incandescent and compact fluorescent light bulbs and are much more efficient at converting electrical power into usable optical power.

Starting Point for Overcoming Barrier to Fusion Power
Posted in Power Management, Energy, News on Thursday, 23 August 2012
The accuracy of a new model for predicting the size of a key barrier to fusion power, which was developed by physicist Robert Goldston of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has been confirmed. Goldston’s model predicts the width of what physicists call the “scrape-off layer” in tokamaks, the most widely used fusion facilities.

Getting to the Heart of Tomorrow's Cardiovascular Technologies
Posted in Power Supplies, Electronics, Power Management, Medical, Features, MDB on Wednesday, 01 August 2012
Cardiovascular disease is the number one cause of death in the world. About 1.2 million Americans suffer from heart attacks every year. Approximately 2,000 Americans get heart transplants each year, but transplant hearts are in short supply, and many thousands of other advanced heart failure patients are left on the waiting list.

A Better Understanding of High-Temperature Superconductors
Posted in Power Management, Lasers & Laser Systems, Energy Storage, Energy, News on Friday, 22 June 2012
Superconductivity, in which electric current flows without resistance, promises huge energy savings – from low-voltage electric grids with no transmission losses, super-efficient motors and generators, and myriad other schemes. But such everyday applications still lie in the future, because conventional superconductivity in metals can’t do the job.
