disconnect, turmoil, Digital Clamp Meters

In electrical and electronic engineering, a current clamp or current probe is an electrical device having two jaws which open to allow clamping around an electrical conductor. This allows the electrical current in the conductor to be measured, without having to make physical contact with it, or to disconnect it for insertion through the probe. Some types of current clamp are used to induce current in the conductor.


The New York Times leads with Federal Reserve Chairman Ben Bernanke indicating that the current economic turmoil could extend well into 2009 as he outlined a series of major changes the central bank will consider in the coming months to ease the pain.

China's leadership called for "calm" as thousands joined anti-Western protests targeting French retailer Carrefour in several China cities, amid anger over foreign criticism. The pre-Olympic turmoil is exposing a disconnect between how China views itself and how it is viewed by many foreigners.
