Infineon also provides the thyristor chips that allow transformers to handle high-voltage direct-current power lines.
Even Thomas Edison bet badly, as in his development of direct-current electricity that proved inferior to alternating current.
Diodes are essential in radios to turn rapidly oscillating radio waves into a smoother direct-current signal that can power a speaker.
None of those are quite like the foc.us, however, which serves up transcranial direct-current simulation (tDCS) -- a controversial form of neurosimulation that transmits current to a particular area of the brain.
But Thomas Edison's idea--that power should be distributed as direct current--is being revived.
Their job is to convert high-voltage alternating current from the mains into low-voltage direct current for mobile phones, laptops, iPods and other electronic gadgets.
ECONOMIST: How a boring gadget saved $2 billion-worth of electricity
One of ABB's specialties is high-voltage direct current links, so-called HVDC.
One of the considerations was the relative safety of direct current - the first electric chair seems to have been built (and then used) to prove that alternating current was more of a killer.
Siemens is also offering high-voltage direct current technology, but ABB is a step ahead.
Its high-voltage direct current system is delivering electricity to the British Petroleum platform in the middle of the ocean.
The cost-lowering potential of direct-payment practices is heartening because the current third-party payment system has failed to stem our burgeoning health cost crisis.
FORBES: Fed Up With Obamacare, Doctors Increasingly Prefer Cash For Care
They can carry five to 20 times more current in the same unit area while reducing the amount of energy lost as heat by 75-97% (depending on whether the current is alternating or direct), even after accounting for all the nitrogen-cooling paraphernalia.
Adherence to direct, source- and sink-based, current-period accounting provides a robust framework for handling emissions from fuels regardless of their origin.
The personal accounts would then encompass an option for 11.4% of wages altogether, a direct savings of about one-fourth from the current 15.3% payroll tax.
Partly because of privatisation, foreign direct investment should finance perhaps 60% of the current-account deficit.
About 3, 500 people are employed at the Swindon plant and the current redundancy programme applies to 360 "direct associates" - those employed in manufacturing.
Good news for equity investors--and a return to current account deficits matched by foreign direct investment inflows that will spur growth and keep Asian currencies relatively strong against the yen.
Upon reflection, policy is best defined using current-period accounting of carbon stocks and flows, ideally with direct, measurement-based, verifiable tallies of GHG emissions from the production and use of all fuels and feedstocks.
Investors willing to take additional risk might also consider leaving their current 401(k) savings in a target-date fund, but direct all new contributions into a domestic equity fund or international stock fund to boost returns, says Michael Francis, president of Francis Investment Counsel, a consulting firm specializing in retirement plans.
India's growth model has been to run a small current-account deficit, financed with high-quality capital inflows, such as foreign direct investment and equity purchases.
India is financing its current-account deficit with volatile foreign fund inflows into the capital markets rather than foreign direct investment, which is a matter of concern, Mr. Subbarao said at an event in Mumbai.
And it could allow co-operatives like the Associated Press to reinstate anti-competitive policies that were found illegal long ago, such as allowing current members to block their direct rivals from joining.
Halfway through their current six-month tour, seven British soldiers have been killed in Helmand - one in direct combat, the other six in insider attacks when Afghan security forces turn their weapons on their foreign partners.
