3 phase brush-less DC (BLDC) motor applications bring higher efficiency and improved performance to electromechanical actuation in automotive systems like pumps, power steering, engine cooling fans and fast positioning drivetrain actuators. Melexis latest pre-driver IC, the MLX83203, deploys EEPROM memory and combined bootstrap and charge pump blocks.
The AAT1274 is a high efficiency, 1.5A high-current boost converter for LED photo flash applications. It maintains output current regulation by switching the internal high-side and low-side switch transistors, pulse-width modulated at a fixed frequency of 2 megahertz. The high switching frequency allows the use of a small external inductor and output capacitor...
The EXP-LED-F4W intrinsically safe LED flashlight from LXflashlights.com is designed to provide an extremely durable and powerful light source for operators who require intrinsically safe approval as well as highly reliable operation. Producing 90 lumens and able to run for up to 80 hours on a set of batteries, this LED flashlight carries intrinsically safe approval...
The Americas photovoltaics (PV) market more than doubled in the first half of 2012 to reach 1.7 Gigawatts (GW) and is set to reach almost 4.3 GW for the full year according to the Q3 PV Demand Report from IMS Research. Installations grew by more than 120 percent in the first half of this year and will help drive the global PV market to grow by at least 3 GW in 2012, according to the research firm.
I have experienced first hand the great learning opportunity such venues provide students to apply what they have learned in the classroom, and have fun (and a fair share of pain) doing it. In addition, this hands-on learning brings greater understanding and gratification of the knowledge acquired in coursework. In addition, a team competition

The PRL-414RSTR is a 1:4 fanout differential RS-422 line driver. It has two sets of floating 124 Ω differential inputs designed to accept RS-422 signals. The PRL-414RSTR high speed fanout line driver facilitates testing and integration of high speed digital communications circuits and distribution of satellite signals.
Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries.
Research by Nosang Myung, a professor at the University of California, Riverside, Bourns College of Engineering, has enabled a Riverside company to develop an "electronic nose" prototype that can detect small quantities of harmful airborne substances.
When you take a dip in the ocean, nuclear fuel is probably the farthest thing from your mind. Uranium floats in Earth’s oceans in trace amounts of just 3 parts per billion, but it adds up. Combined, our oceans hold up to 4.5 billion tons of uranium – enough to potentially fuel the world’s nuclear power plants for 6,500 years.
Dell Inc warned of a challenging second half and slashed its full-year earnings outlook as customers cut back on computer purchases ahead of the launch of Microsoft's Windows 8 software, sending its shares down more than 4 percent.
NASA's Mars rover Curiosity, dispatched to study if the Red Planet could have hosted life, will take its first test drive on Wednesday. The one-ton, nuclear-powered robotic geologist, which landed inside a Martian crater on August 6, will get instructions for a 30-minute drive, mission manager Michael Watkins told reporters on a conference call Tuesday.
In a few weeks, about 2,800 cars, trucks and buses will start talking to each other on the streets of Ann Arbor, Mich., in a giant experiment that government officials are hoping will lead to safer roads.
Twelve Yale investigators were among 202 researchers to receive Young Investigator Grants from the Brain & Behavior Research Foundation (formerly NARSAD). The $11.9 million program helps support researchers with promising ideas about how to understand and treat mental illness....
The multibillion-dollar patent trial involving the world's biggest smartphone companies, Apple and Samsung, was set to go to a U.S. jury Wednesday in an epic struggle over the wildly popular iPhone. Apple Corp. argues that Samsung Electronics Co. should pay $2.5 billion for ripping off its iPhone...
