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.

Tailoring Metal Oxides for Green Technological Applications
Posted in Batteries, Electronics & Computers, Power Management, Metals, Energy Storage, Solar Power, Renewable Energy, Energy Harvesting, News on Thursday, 26 April 2012
Harnessing solar energy can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice ‘sandwich.’ "Metal oxides can be tailored to meet all sorts of needs, which is good news for technological applications, specifically in energy generation and flat screen displays,” said Louis Piper, assistant professor of physics at Binghamton University.

Boosting Energy Efficiency of Multi-Hop Wireless Networks
Posted in Batteries, Power Management, Energy Efficiency, Communications, Wireless, News on Wednesday, 25 April 2012
Multi-hop wireless networks can provide data access for large and unconventional spaces, but they face significant limits on the amount of data they can transmit. North Carolina State University researchers have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.

Transient Voltage Suppressor Arrays
Posted in Power Management, Products, MDB on Sunday, 01 April 2012
Microsemi (Aliso Viejo, CA) has introduced two new non-magnetic, 500-watt transient voltage suppressor (TVS) arrays. The devices were designed specifically for MRI machines to guard against circuit damage caused by electrostatic discharge, electrical fast transients, and the effects of secondary lighting. The USBQNM504xx and USBQNM504xxC TVS arrays protect uni- and bi-directional lines, respectively. They are offered in a non-ferrous, quad flat no-lead 143- pin metal lead frame. Additional features include peak power rating of 500 watts for an 8/20 microsecond pulse and protection against electrostatic discharge (ESD).
