U.S. wireless carrier Sprint (S.N) said on Thursday it will move into the hot market for tracking technology that lets auto insurers monitor how, where and when their customers drive.
Researchers at the University of California, Riverside believe they can extend the range of electric vehicles by at least 10 percent by taking into account real-time traffic information, road type and grade and passenger and cargo weight.
Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries – a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost.
Charging stations for electric vehicles are still a few years, possibly decades, away from being in every household garage—priced at upwards of $20,000 per unit. Talk about keeping up with the Jones! Despite the challenges of price point, materials, and a general public skepticism, companies are making great strides in designing chargers that are more durable, efficient, functional, and versatile than their predecessors.
Scientists in Germany have come up with a new fluid for cooling the expensive batteries in electric cars and thereby extending their life, another potential step in improving the cost efficiency of electric propulsion. The fluid, dubbed CryoSolplus, absorbs heat more effectively than either air or water and could allow for tighter packing of batteries under the hood, according to a team of researchers at the Fraunhofer Institute for Environmental, Safety and Energy Technology in Oberhausen.
Barrels and cones dot an open field in Saline, Mich., forming an obstacle course for a modified vehicle. A driver remotely steers the vehicle through the course from a nearby location as a researcher looks on. Occasionally, the researcher instructs the driver to keep the wheel straight — a trajectory that appears to put the vehicle on a collision course with a barrel.
Pininfarina, the Italian automaker, has come up with a solution to long commutes and rude passengers on the subway with its Personal Rapid Transit Vehicle.
The urbanization of the world continues to evolve – not only in emerging nations, but in the industrialized world like Europe as well. Already more than half of all the earth's inhabitants live in cities; by 2030, it will be 60 percent. As densely populated sites of human cohabitation, cities are ecological and social tinder boxes. Experts believe that the need for urban space will double by 2050. Megacities also generate megaproblems: With an insatiable appetite, they consume energy, raw materials and space – in addition to producing pollutants, wastewater streams and mountains of rubbish. The transportation system is overloaded, resulting in overcrowding, lack of parking and traffic jams.
Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher at Case Western Reserve University argues. Rather than continue the futile effort to tweak that material - platinum - to make it work better, Chemistry Professor Alfred Anderson urges his colleagues to start anew.
The constant hunger to break new records has turned boat building into a high-tech business. The racing yachts that compete at international regattas today are sporting machines designed to reach top speeds. The process of optimizing the boats has been ongoing for decades.
SALT LAKE CITY, July 12, 2012 – University of Utah physicists invented a new "spintronic" organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices.
Needing only two additional components, the AL5801 linear LED driver enables designers to simplify automotive interior, signage, and general lighting control circuits. Integrating a 100V rated N-channel MOSFET with a pre-biased NPN transistor, this small footprint SOT26 packaged device will drive chains of up to 30 low-power, series-connected LEDs with currents from 20mA to 350mA.
Honeywell announced the release of its new Basic Board Mount Pressure Sensors, NBP Series. These are a cost-effective, basic performance, mV output, unamplified, uncompensated, high quality, and high resolution solution for customers seeking high-volume, economical board mount pressure sensors.
Rochester Electronics has continued to manufacture AMD’s 80C188 commercial grade 16-Bit microcontrollers in a 68-pin PLCC package. Utilizing Rochester’s eight-million AMD80C188 die, the 80C188 is available in any original AMD package and speed option. Rochester can also manufacture a lead-free version, which is ideal for newer applications that require modern environmental standards including RoHS.
Transducers USA has introduced their new piezo ceramic MLCT (Multilayer Ceramic Transmitter) series. Its unique simple acoustic multi-layer ceramic construction produces a high output of 80 Db with only 16V low driving voltage. Its milliwatt of power consumption and high conversion efficiency lead to an even broader range of applications.With an overall size of 30 X 20 X 1.5mm, the series is ideal for flat and narrow spaces.
PITTSBURGH—Drivers can struggle to see when driving at night in a rainstorm or snowstorm, but a smart headlight system invented by researchers at Carnegie Mellon University's Robotics Institute can improve visibility by constantly redirecting light to shine between particles of precipitation.
Linear Technology Corporation announces the LT3504, a quad 1A output, 40V step-down switching regulator with 100 percent duty cycle operation. The LT3504’s 3.2V to 40V input voltage range makes it ideal for automotive and industrial applications that require multiple outputs.

Wi-Fi is coming to our cars. Ford Motor Co. has been equipping cars with Wi-Fi transmitters since 2010; according to an Agence France-Presse story last year, the company expects that by 2015, 80 percent of the cars it sells in North America will have Wi-Fi built in. The same article cites a host of other manufacturers worldwide that either offer Wi-Fi in some high-end vehicles or belong to standards organizations that are trying to develop recommendations for automotive Wi-Fi.

In the previous installment of this blog, I discussed the tremendous growth of electronics in the car. The drivers (no pun intended) of this growth vary from consumers demanding more information-entertainment (“infotainment”) and connectivity — the term carnectivity has emerged as a catch-all descriptor -- while on the road to governmental mandates intended to make cars safer, given all the new whiz-bang but potentially distracting features being added to vehicles. Let’s now turn our attention to some of the trends in infotainment and carnectivity, what’s being done to simplify these complex system designs.
