In response to an Obama Administration auto task force report, Plug In America on Tuesday proposed a plan to make GM’s Chevy Volt and other plug-in cars more affordable, noting that most advanced new technologies are initially more costly. California law requires that the Volt and other plug-in hybrids come with a 10-year warranty. To ensure this longer life, automakers are as much as doubling the size of the battery pack, increasing cost to manufacturer and consumer.
Advanced technology vehicles have yet to gain a foothold in the mainstream auto industry. Hybrids boast a fuel economy upwards of 40 mpg, but are too pricey for your average consumer. Similarly, “clean diesel” sports high MPG ratings, but diesel is prohibitively expensive. The more exotic ATV’s (air-cars, biodiesel, solar) are aesthetically morose. Pure electric vehicles (PEVs) lack the necessary infrastructure to support them. Welcko’s Mogwai Electric Vehicle (or MEV) is the first ATV with potential mainstream viability
The California Energy Commission (CEC) is moving ahead with a proposal that could make Plasma TVs legally obsolete. Based on the 2008 Report, “Draft Efficiency Standards for Television” (which drew heavily from Pacific Gas and Electric Company findings), the proposal would set a cap on the maximum active mode power usage (watts). This would effectively ban the sale of Plasma, DLP, rear projector, and certain LCD TV’s in California
From planar HEXFETs to TrenchFETs and superjunction FETs, silicon power MOSFETs have continued to evolve for the last 30 years to satisfactorily serve numerous markets. In fact, during that period, there have been some two orders of magnitude improvement in performance. However, this silicon power device is rapidly approaching maturity
Typically, industries use standards to improve product quality and enable component sharing across projects. In practice, such standards achieve wide acceptance since the synergistic effects provide significant benefits to the user community. The hardware and software industry is full of such standards, but there is an exception: the deeply embedded microcontroller market
For the last half-century, sensors based on the Hall effect have provided a low-cost, solid-state option for sensing any object that incorporates a magnetic field. Hall effect sensors are based on the discovery by Dr. Edwin H. Hall in 1879. He found that a thin conductive material, placed in a magnetic field, formed a difference in potential (voltage) at the opposite edges that was
Tata Motors has unveiled the world’s cheapest car, with potential for a vast standard of living increase. And Greenpeace doesn’t like it. The same organization that supported a ban on chlorine in drinking water feels that the mass proliferation of cheap automobiles is a bad thing. Despite its eco-friendly 47 MPG rating, the Tata Nano is seen as a threat to the environment. Why? Because lots of people want to buy them.
Because finite impulse response (FIR) filters use a mathematical algorithm to process information, engineers rely on them when an analog filter just won't do. “FIR filters appeal to people who don't want to become filter designers”, explained Grant Griffin, President, Iowegian International. "They just want to use a filter to solve a problem
Moving forward, what technology will dominate energy harvesting?
Day after day, reports of the dangers of climate and climate change circulate in the news, often filled with confusing data and debate. In an effort to improve understanding of climate science, a group of government agencies has combined efforts to produce "Climate Literacy: The Essential Principles of Climate Science."
A lithium-ion battery electrode described this week in the journal Nature can deliver electricity several times faster than other such batteries. It could be particularly useful where rapid power bursts are needed, such as for laser weapons or hybrid race cars. Test batteries based on the new electrode--developed by Gerbrand Ceder, a professor of materials science at MIT--can be discharged in 10 seconds.
In 2007, Al Gore shared the Nobel Peace Prize for his efforts to “build up and disseminate greater knowledge about man-made climate change.” In his Oscar-winning documentary, An Inconvenient Truth, Gore screeched, “The scientists are virtually screaming from the rooftops now. The debate is over! There’s no longer any debate in the scientific community about this.”
It’s a fact that consumers want end products that give them the most user interaction. Two of the most popular examples on the market are Apple’s iPhone and Nintendo’s Wii. These end products serve very different purposes to their desired consumers, but share electronic advances that make these products, amongst others, an interactive experience for the user. In this month's Industry Focus, we talked to six different companies
For those who’ve never been, Electronics West is one of seven shows (including EW, Medical Design and Manufacturing West, Pacific Design and Manufacturing West, Automation Technology Expo West, Plastec West, West Pack, and Green Manufacturing West) co-located within the Anaheim Convention Center. One badge earned admittance to all, so from 10-12 February, I “attended” each.
Arizona State University’s Flexible Display Center (FDC) recently unveiled the world’s first flexible touchscreen display. Developed in conjunction with E Ink Corporation and DuPont Teijin Films, the active matrix display is capable of real-time user input, and can send and receive information. The applications for such a device, particularly in the military sector, are endless
Hundreds of demonstrators are urging Congress to pass legislation to reduce greenhouse gases, and they're using the Capitol power plant as a symbol of the problem. Despite attempts by lawmakers to clean up the power plant in southeast Washington, it still burns coal and accounts for a third of the legislative branch's greenhouse gas emissions. Monday's rally on Capitol Hill was being followed by a march to the power plant, where some demonstrators planned to block entrances and get arrested.
Enclosure manufacturers strive to anticipate the demands of the electronics marketplace with state-of-the-art enclosure designs. The challenge is for designers to develop products with unique features that meet customers’ needs, yet still appeal to the broadest market possible. With this in mind, manufacturers endeavor to engineer enclosures with features, options and accessories that provide a breadth of solutions specific to customers’ applications.
Piezoelectric ceramic components composed of Lead Zirconate Titanates (PZT) have enabled many recent technological innovations in the automobile industry. PZT components can be found throughout many state-of-the-art vehicles, enhancing safety, performance, energy-efficiency and comfort. For example, you will find PZT sensors under the hood detecting engine knocking, PZT transducers in the gas tank measuring the fuel level, PZT actuators operating valves
More than 50 million people in the United States have disabilities, a number that is growing rapidly as the population ages. This growth has sparked renewed interest in developing more sophisticated assistive technologies to enable an oftentimes disabling environment. This growth presents semiconductor suppliers with an opportunity to enable this field
Shai Agassi, CEO of Better Place, wants to make electric cars viable. His solution? Spread battery-swapping stations throughout the world, using a fee structure similar to cell-phone contracts. According to Better Place’s site, “The batteries of a zero-emission vehicle need three things in place for optimum functionality: charging spots, battery switching stations, and software that automates the experience.” Their solution is a network of stations where depleted batteries can be swapped out for fresh ones.
Which green technology has the most commercial potential?
This "compromise" is an example of the misguided cuts that have been made in the stimulus package in the name of savings. "Clean Coal" and Nuclear power are among the best alternatives to oil we have, and to cut funding for these important technologies is shortsighted. "Clean Coal" and Nuclear power are among the best alternatives to oil we have, and to cut funding for these important technologies is
Many “standard” and proprietary protocols use the media-access controller (MAC) and the physical circuits (PHY) associated with IEEE 802.15.4 radios. Those protocols use their own arrangements of bits and bytes to transfer information between nodes, but none of them use the Internet Protocol (IP). So they cannot directly communicate with Internet-based devices and Web servers/browsers.
In general, high frequency operation allows the use of small-sized passive components in switch mode power supplies (SMPS), while it causes switching losses to increase in a hard switching mode. To reduce switching losses at high switching frequencies, many soft switching techniques have been developed. Among them, load resonant techniques and zero voltage transition techniques are widely used.
Obama’s position on tailpipe emissions presents a strange paradox: traditional supporters of states’ rights are clamoring for one national standard, while federalists want the states to decide. It seems that we’ve entered bizarro world. But it goes deeper. Allowing states to set their own emissions standards is a thinly-disguised attempt to impose higher national standards through backdoor means.
