New Method of Controlling Tiny Devices
Posted in Electronics, Power Management, Medical, News, MDB on Wednesday, 06 March 2013
Electromagnetic devices all require an electric current to create the magnetic fields that allow them to function. But as devices become smaller, being able to efficiently deliver a current to create magnetic fields becomes more difficult. Researchers at UCLA say that they have developed a method to switch tiny magnetic fields on and off with an electric field, instead of the traditional approach of running a current through a wire, which they say could lead to big changes in storing digital information and powering motors in small hand-held devices.

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.

High Power LED Chip Array Packaging
Posted in Manufacturing & Prototyping, Custom & Contract Manufacturing, Electronics, Electronic Components, Power Supplies, Thermal Management, Power Management, Medical, Lighting, LEDs, Features, MDB on Thursday, 01 November 2012
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.
