The research team of professor Linda Nazar, graduate student David Xiulei Ji and postdoctoral fellow Kyu Tae Lee are one of the first to demonstrate robust electrochemical performance for a lithium-sulphur battery.
A Power over Ethernet (PoE), Power System-on-a-Chip (Power SoC) with 2kV integrated isolation, the AS1854 from Akros Silicon eliminates opto-couplers and integrates functionality of up to nine separate ICs, including a third-generation IEEE 802.3af/at PD controller and quad-output digital power DC-DC converters.
Measuring 3 x 3 mm with an emission angle of 80°, the 1-W OSLON SSL LED from OSRAM Opto Semiconductors accepts 350 mA for a typical brightness of 110 lumens in 5,700K and 6,500K white, with a maximum luminous flux of 130 lumens (155 lumens at 700 mA).
Like tiny Jedi knights, tunable fluidic micro lenses can focus and direct light at will to count cells, evaluate molecules or create on-chip optical tweezers, according to a team of Penn State engineers. They may also provide imaging in medical devices, eliminating the necessity and discomfort of moving the tip of a probe.
Alicia Istanbul woke up one recent Wednesday to find herself locked out of the Facebook account she opened in 2007, one Facebook suddenly deemed fake.
The head of the world's most popular search engine urged college graduates on Monday to step away from the virtual world and make human connections. Speaking at the University of Pennsylvania's commencement, Google chairman and CEO Eric Schmidt told about 6,000 graduates that they need to find out what is most important to them — by living analog for a while.
Targeting 13-W or 26-W powered device applications such as IP phones, wireless access points, or security cameras, the TPS23754 Power-over-Ethernet (PoE) controller from Texas Instruments supports DC/DC converter topologies that can achieve higher than 90 percent power conversion efficiency.
The Mu-chip (µ-chip) is Hitachi's pioneering contribution to smart tag technology. It is a radio frequency identification (RFID) microchip that is small enough to be embedded in paper.
President Barack Obama wants drivers to go farther on a gallon of gas and cause less damage to the environment — and be willing to pick up the tab.
In carrier networks, the fiber plant uses Dense Wavelength-Division Multiplexing (DWDM) technology to combine more than 80 channels to transport the Internet traffic. Today, these DWDM channels are dominated by 10Gb/s line rate and channels are separated by a 50GHz spacing. With limited fiber, these 10G channels are the constraints at the critical fiber route now.
Let's start with a tough question: What is the difference between TPMS system and PKE system? Nothing! A TPMS system is placed inside the wheel and composed of a sensing device that measures temperature and pressure. When appropriate, for example before starting the engine, the car requests a measurement through a wireless link. If a pressure default occurs in one of the wheels, the car warns the driver through a signal on the dashboard. In PKE applications, the user carries a key fob device which contains an encoded identifier (ID). When the driver enters their car, the car requests the key fob ID through the wireless link. If the ID matches the ID stored by the car,
Here is a collection of articles on the subject of Solid-State lighting.
Just as they have played a key role in advancing industries such as PCs, cellular telecommunications and automotive, digital signal processors (DSPs) are playing an increasingly important role in advancing medical imaging to provide faster, more accurate diagnoses and treatment.
With over 8,000 attendees, this year’s Embedded Systems Conference (ESC) was a pleasant surprise to an industry expecting a low turnout. Held in San Jose from March 30 to April 2, the event had a nice assortment of new tech and devices. Here is our second portion of our two-part coverage of the event.
There's an old saying, "you can even get used to hanging, if you hang long enough". This industry has been on a rollercoaster for over a decade, between the Dot-Bomb, the Telecom collapse, the Internet, the housing bubble, the bank crisis, and disruptive technologies, we've been beaten about like a Pinata on Cinco de Mayo.
