Many modern portable devices must be shipped with a battery installed so that a customer can power it up initially without any battery installation or charging. Any excessive current “leakage” from the components connected to the battery may result in a dead device in the hands of a customer.
Anderson Power Products (Sterling, MA) announced the addition of a five-position offering to the Mini SPEC Pak connector family. This environmentally sealed and touch safe connector houses up to five contact positions in a
A team of University of California, Riverside’s Bourns College of Engineering students created a roof tile coating that when applied to an average-sized residential roof breaks down the same amount of smog-causing nitrogen oxides per yearas a car driven 11,000 miles
Announced at a press conference at meeting of the American Astronomical society, was the discovery of a planet that is 17-times heavier than earth called Kepler-10c. The planet exists in the Draco constellation, about 560 light-years from earth. The latest smart phone security: If someone does something suspicious with a phone...
Faster electronic device architectures are in the offing with the unveiling of the world’s first fully two-dimensional field-effect transistor (FET) by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab). Unlike conventional FETs made from silicon, these 2D FETs suffer no performance drop-off under high voltages and provide high electron mobility, even when scaled to a monolayer in thickness.
Solar Impulse 2, a.k.a. the "Round-the-World" solar airplane, is a single-seater airplane made from carbon fiber with 17,000 solar cells that supple four electric 17.5 CV (each) with energy. Those solar cells recharge the lithium batteries that allow the plane to fly at night.
President Barack Obama's plan to curb power plant pollution put Democrats running for office in coal country in a tough spot on Monday: Criticize their president, or side with him and become part of what could be a major drag on their region's economy.
President Barack Obama's ambitious plan to reduce the gases blamed for global warming from the nation's power plants gives many coal-dependent states more lenient restrictions and won't necessarily be the primary reason coal-fired power plants will be retired.
A team of international scientists led by Professor Jagadese J Vittal of the Department of Chemistry at the National University of Singapore's (NUS) Faculty of Science has successfully unraveled the chemical reaction responsible for propelling microscopic crystals to leap distances up to hundreds of times their own size when they are exposed to ultraviolet (UV) light.
Imagine being able to carry all the juice you needed to power your MP3 player, smartphone and electric car in the fabric of your jacket? Sounds like science fiction, but it may become a reality thanks to breakthrough technology developed at a University of Central Florida research lab.
As President Barack Obama prepares to announce tougher new air quality standards, lawmakers in several states already are trying to blunt the impact on aging coal-fired power plants that feed electricity to millions of consumers. The Obama administration on Monday will roll out a plan to cut earth-warming pollution from power plants by 30 percent by 2030, further diminishing coal's role in U.S. electricity production in the process.
A Swiss-made solar-powered aircraft has made a successful inaugural flight as its makers prepare for what they hope will be the first round-the-world solar flight. The Solar Impulse 2 team said the aircraft spent 2 hours and 17 minutes in the air above western Switzerland early Monday. They plan several other flights over the coming months.
In a sweeping initiative to curb pollutants blamed for global warming, the Obama administration unveiled a plan Monday that cuts carbon dioxide emissions from power plants by nearly a third over the next 15 years, but pushes the deadline for some states to comply until long after President Barack Obama leaves office.
The Terra 53 Multistandard EV Fast Charger from ABB (Switzerland) is their flagship 50 kW DC fast charging station, meeting both SAE Combo and CHAdeMO standards for battery electric vehicles. ABB has led the market as the first manufacturer in the world to meet both standards in a single charging unit....
Today’s microprocessor-based electronics can be found in just about everything in the home. Inside the dishwasher, stove, refrigerator, television, telephone and a myriad of other devices including home computers. Shortly after the introduction of home computers, the demand for low cost uninterruptable power supplies (UPS) significantly increased....
Two of the issues that come up frequently when discussing wind energy options are the noise and the actual output of the turbine. The noise issue is more of a problem for big turbines, that may look majestic from far away, when you live nearby they can make a bit of noise.
The Archimedes tech firm has designed a wind turbine based on the real (Ancient Greek Mathmetician) Archimedes’ screw pump design. Its design allegedly reduces the noise associated with traditional wind turbines. It also supposedly has an energy yield that is “80 percent of the maximum that’s possible,” which compares favorably to the conventional 25-50% of most turbines....
Solar micro inverters are an emerging segment of the solar power industry. Rather than linking all solar panels in a solar installation through a central inverter, solar micro inverter systems instead place smaller, or “micro,” inverters in line with each individual solar panel....
Schaefer Inc. (Hopkinton, MA) unveiled the Second Generation of the LW 5100 Series of liquid cooled electronic loads featuring user friendly touch screen panel and enhanced functionality. These built-to-project loads are housed in a compact case that provides...
Linear Technology Corporation (Milpitas, CA) introduced the LTM8057 and LTM8058, 1.5-W output µModule (micromodule) DC/DC converters with 2-kVAC galvanic isolation (production tested to 3 kVDC) in a 9-mm x 11.25-mm x 4-mm BGA (ball grid array) package. The devices operate from an input voltage...
Broadcom Corporation (Irvine, CA) introduced a new multi-standard smartphone power management unit (PMU) that drives Rezence technology into the mainstream while providing compatibility with existing deployed standards.
SL Power Electronics (Ventura, CA) announced its 425-W, single output TU425 Series AC/DC power supply. This offering addresses the unique needs of all types of test equipment such as oscilloscopes, analyzers, test boards, chromatography mass detectors as well as
International Rectifier (El Segundo, CA) introduced the µIPM-DIP family of highly integrated, compact Integrated Power Modules (IPM) for low power motor drive applications including fans, pumps, air purifiers and refrigerator compressor drives.
U.S.-based First Solar delivered on expectations in 2013 to become the leading Engineering, Procurement and Construction (EPC) company in the global photovoltaic (PV) industry, even though it is likely to be surpassed in 2014 by Chinese EPC TBEA SunOasis, according to a new report from IHS Technology.
