Harnessing the Power of Spinach
Posted in News, News, Electronics, Energy Harvesting, Renewable Energy, Solar Power on Friday, 07 September 2012
Vanderbilt University researches have developed a way to combine Photosystem 1 (PS1), the photosynthetic protein that converts light into electrochemical energy in spinach with silicon (the material used in solar cells), in a fashion that produces substantially more electrical current than has been reported by previous biohybrid solar cells.
Getting to the Heart of Tomorrow's Cardiovascular Technologies
Posted in Features, Electronics, Power Management, Power Supplies 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.
Seven Advantages of Membrane Switches for Medical Electronics
Posted in Features, Electronics, Displays/Monitors/HMIs, Drug Delivery & Fluid Handling, Patient Monitoring on Sunday, 01 July 2012
With the large number of user interface options available today, it is easy to forget why the membrane switch is an excellent choice for medical instrumentation. The basic advantages are still the same as they were two decades ago, when membrane switches became the interface of choice for a multitude of products, including toys and games, high-end appliances, industrial controllers, and automotive controls. These advantages have been enhanced by developments in materials, processes, and design expertise.
Test & Measurement System
Posted in Products, Electronics on Sunday, 01 July 2012
Keithley Instruments (Cleveland, OH) has introduced the Model 2657A High Power System SourceMeter® instrument, which offers a highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current meters. It can source or sink up to 180W of DC power (±3,000V@20mA, ±1500V@120mA). The 6-1/2-digit measurement engine built into this system enables 1fA (femtoamp) current measurement resolution to support low-leakage requirements.

Scientists at the U.S. Naval Research Laboratory, Electronics Science and Technology Division, have developed high-band-gap solar cells capable of producing sufficient power to operate electronic sensor systems at water depths of 9 meters.
New Approach to Graphene Electronics
Posted in News, News, Electronics, Power Management, Energy Efficiency, Renewable Energy, Solar Power, LEDs on Tuesday, 21 February 2012
Graphene has been touted as the next silicon, but it is too conductive to be used in computer chips. A University of Manchester team led by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research.
EMI Filters
Posted in Products, Electronics on Wednesday, 01 February 2012
LCR Electronics (Norristown, PA) offers two new series of EMI filters for MRI shielded rooms. The 058 series filters are designed to mitigate any unwanted EMI noise through MRI room telephone, alarm, and data lines. The UL-recognized 059 series filters provide EMI suppression along the main power lines. The dual line filters are rated 120/277 VAC 50/60 Hz up to 50 A at 60 °C, 300/600 VDC lineto- ground and line-to-line, all with an impedance line-to-line rating of 600 ohms and a line-toground rating of 300 ohms. The series has a stop band of 100 dB from 20 KHz to 10 GHz for phone lines, 100 dB from 150 KHz to 10 GHz for data lines, and 100 dB from 14 KHz to 1 GHz for alarm lines. Individual or multiple 058 filters can be supplied pre-installed in an enclosure with removable covers for I/O connections and a threaded conduit pipe for installation against shielded room interference. The 059 filters are available in single, dual, and three-phase configurations and provide 100 dB attenuation from 5 MHz to 10 GHz per MIL-STD-220 and feature a sealed filter compartment with a removable shielded cover for input connections as well as a threaded conduit pipe for installation against shielded room interference.
