NHLBI stops enrollment in study on resuscitation methods for cardiac arrest Nov 7, 2009
The Resuscitation Outcomes Consortium (ROC), the largest clinical research network to study prehospital treatments for cardiac arrest in the United States and Canada, tested both resuscitation strategies as part of the Prehospital Resuscitation using an IMpedance valve and Early versus Delayed (ROC PRIMED) clinical trial. An impedance valve, also called an impedance threshold device (ITD), is a small, hard plastic device about the size of a fist that is attached to the face mask or breathing... (EurekAlert!)
Caltech scientists solve decade-long mystery of nanopillar formations Oct 23, 2009
"In their model, the difference in acoustic impedance between the air and polymer is believed to generate an imbalance in phonon flux that causes a radiation pressure that destabilizes the film, allowing pillar formation," says Troian. "Their mechanism is the acoustic analogue of the Casimir force, which is quite familiar to physicists working at the nanoscale.". (EurekAlert!)
Finally, a new Wii exercise game that’s fit for kids Oct 5, 2009
It calculates your body mass index, and how much of you is fat, according to Withings, by running a current through your body and subtracting the amount of water it detects - a technique called bioelectric impedance measurement. The current from the scale is harmless, for most people. (Boston Globe)

Analysis: Is TI ready for a major analog IC acquisition? Mar 27, 2009
"When you are the No. 1 player with a 13 percent market share there is a strong opportunity to continue to gain share without structural impedance in the way," he said. "Our view right now is that the portfolio we have is extensive and we don't have large gaps. While we don't rule out doing a big acquisition, the concentration of acquisition activities, as demonstrated by our actions, is really more in the smaller space.". (EETimes)
SUPER3C project, superconducting coated conductor cable Mar 26, 2009
The basic features of HTS cables are their ability to transport power at a lower voltage than conventional cables, which drastically diminishes the reactive power and the energy losses, and their low impedance, thus allowing direct linking of substations saving transformers and simplifying the grid. Larger amounts of power can be transmitted more efficiently with lower losses. (EurekAlert! -- Business News)
