At the American Telemedicine Association’s annual meeting recently the results of a national survey were revealed. The survey of health care and information technology professionals, sponsored by Intel, found that a majority of decision makers believe that the emergence of telehealth will have a major role in improving the care for the globally aging population, aka the “baby boomers.
The path to achieving energy efficiency is ridden with obstacles. Q: If we continue to increase the power efficiency of a product, are we approaching the point of diminishing returns? Will it eventually detrimentally impact the cost of the product? Doug Bailey, VP marketing, Power Integrations This is an interesting question.
The earliest embedded systems – industrial automation and scientific instruments communicated with operators using physical actuators: knobs, dials, gauges, indicator lights, etc. Today’s intelligent devices, especially in consumer electronics, feature more sophisticated operator interaction and boast user interfaces (UIs) comparable to desktop applications.
Consumers are starting to complain about infrared (IR) remote control’s inability to cope with the demands of modern media devices. A recent study by Strategy Analytics1, for instance, found that while early adopters of advanced Internet TV services (such as AppleTV, Hulu, and AT&T U-Verse) value the ability to personalize and share their content, the adoption rate could be slowed because consumers “want better control devices and superior user experience”.
Simon Whittle, Nujira Ltd. The new generation of data-oriented digital communications networks being rolled out in the cellular, broadcast, military and other environments carries a sting in the tail for RF designers. In order to achieve high data rates, these new standards use advanced modulation techniques such as OFDM which significantly increase the variations in amplitude of the transmitted signal.
WiMAX is the only globally deployed 4G technology that today is enabling primary broadband in developing markets and providing 4G services in the most advanced telecommunication markets. With millions of subscribers today and triple-digit cumulative average growth predicted through 20141, WiMAX is starting to enjoy mass market adoption.
To overcome the ever increasing end-user performance requirements of mobile devices, new multi antenna devices are being developed utilizing the recent advances in Multiple-Input Multiple-Output (MIMO) techniques, such as transmit diversity and spatial multiplexing introduced e.g. in IEEE802.16 standard.
By Graham Celine, Azimuth Systems The marketing battle between WiMAX and LTE is raging in an effort to declare which is the best solution, and vendors and service providers are racing to put stakes in the ground to claim the first or most predominant network delivering wireline speeds. However, the true challenge still lurks in the background and has yet to raise its head: which technology will work better, which will provide more throughput, which will offer better range and which will deliver more flexible mobility? The ability to put each of these technologies through their paces and comprehensively test and benchmark the performance of the network is pivotal to the success of either technology’s rollout.
Evergreen Solar, Inc., a manufacturer of String Ribbon™ solar panels with its proprietary silicon wafer technology, recently unveiled its upcoming line of higher efficiency solar panels featuring its newly developed BOOST™ Cell Technology, at Intersolar 2010 in Munich, Germany. The new ES-D and ES-E series of panels for residential and commercial markets feature Evergreen’s new Boost cell technology that uses micro wires instead of conventional bus-bars to reduce cell shading, improve current collection and ultimately increase the overall panel efficiency.
Siemens Energy and Prysmian Powerlink will connect two North Sea offshore wind farms to the German grid using a high voltage direct current (HVDC) link for transpower. The order awarded to the BorWin2 consortium is worth more than €500 millio. The Veja Mate and Global Tech 1 offshore wind farms, which will have a combined power generating capacity of 800 MW, will be connected to the grid via a submarine cable link carrying HVDC.
National Semiconductor Corp. recently announced that it has reached new deals related to its SolarMagic technology with Green Energy Solar (GESolar) and QC Solar. SolarMagic monitors and maximizes the energy harvest of each individual PV panel through a combination of advanced algorithms and leading-edge mixed-signal technology.
Following a record-breaking year of capacity additions in 2009 - with 9.8 GW of wind projects installed - the US wind market finds itself confronting a growth-constrained 2010 and a near-term market landscape wrought with increased competition, according to a new market study, US Wind Power Markets and Strategies: 2010-2025 from IHS Emerging Energy Research.
WASHINGTON- The U.S. Environmental Protection Agency (EPA) is recognizing three universities with the Combined Heat and Power (CHP) awards for generating power and thermal energy while saving energy, lowering greenhouse gas emissions and decreasing air pollution, which can reduce impacts on the public’s health.
Washington, D.C., -- A new energy bill introduced by Sen. Richard Lugar (R-Ind) wisely uses energy efficiency as the core of its provisions, the Alliance to Save Energy said today. The Lugar Practical Energy and Climate Plan focuses on money-saving efficiency policies designed to create long-term energy savings for cars and trucks, new buildings and appliances, existing homes and commercial buildings and industry.
DEVENS, Mass.,(BUSINESS WIRE) -- American Superconductor Corporation, a global power technologies company, announces in conjunction with Global Wind Day 2010 that it has achieved a significant milestone by supporting the production of more than 15,000 megawatts (MW) of wind power worldwide with its proprietary power electronic solutions.
