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.
In a recent study, a team of researchers from Hewlett-Packard Laboratories in Palo Alto, California, have fabricated and demonstrated a hybrid memristor/transistor circuit for the first time. The team demonstrated conditional programming of a nanomemristor by the hybrid circuit, showing that the same elements in a circuit can be configured to act as logic, signal routing, and memory.
Fox Electronics' 1-V F200 Series oscillators come in a 2.5 mm × 2.0 mm package and feature a standby function that reduces the oscillator's current consumption to 5 µA for efficient power use. The F200's low current draw of 2.5 mA across the 1.8 MHz to 32 MHz frequency range and 3.5 mA from 32.1 MHz to 50.0 MHz makes the oscillator series appropriate for
The 3D@Home Consortium celebrates that its membership now totals 40 companies as it continues to increase its activity in all phases of 3D content creation, distribution, marketing, education and products. Newest members to the consortium include General Display Technologies, NXP Semiconductor and Micronas. A full list of members is available on the consortium website at www.3DatHome.org.
C&K Components has developed a micro-miniature, side-actuated, right angle detect switch in a low profile package. Designated the SDS Series, the detect switch sits 2 mm off the PCB while delivering 2 mm overtravel and a low actuation force of 75 g max. In addition to medical and consumer electronics, these detect switches are appropriate for
Incorporating two hot-swap redundant power modules, the ARS24-150 Energy System power shelf from DongAh Elecomm incorporates battery management and a DC distribution panel in a 3U rackmount enclosure. The Ethernet-enabled 24-V 150-A module includes features such as remote sense and enable, AC-OK, DC-OK and active current sharing
MEN Micro Inc., offers the P512 reflective memory PMC offering real-time redundant memory storage across multiple computers in a networked system. In addition to high transmission speeds and flexibility, the 32-bit/33 MHz P512 is said to offer increased data security as well as expanded memory capacity, since memory elements can be
Constructed in a pinched contact structure and with a fully-insulated bottom plate, the 5846 Series of low-profile board-to-board connectors from AVX protects the contacts from vibration, drop shock, and short circuits. The 5846 Series connectors are available in 20 to 80 positions with a positive mating contact with audible and tactile “click” feedback. Other specifications include: 0.3 A rated contact current, 50 V rated contact voltage, and an operating temperature range
The JT22G and JT32G, from Jauch, are temperature-compensated oscillators with a frequency stability down to ±0.5 ppm. The oscillators have a standard operating temperature range from -20°C to 70°C and an extended operating temperature range from -30°C to 85°C. Other features include typical frequencies of
Advanced Analogic Technologies Inc. announced the AAT3620, a fully integrated single-cell Lithium-ion battery charger capable of supplying up to 2 A charge current in a 3 × 3 mm TDFN package. This dual mode produce provides a switching charger during Constant Current (CC) and Constant Voltage (CV)mode. To minimize EMI and RFI emission, the device
Using planar transformers, a converter from Premo features a power range to 10 kW. This technology includes a high input voltage level (500 V to 1,000 V), and switching frequency can be defined between 70 kHz to 160 kHz. Other examples include: less than 35 W of losses at 100°C, and compliant with standards including IEC 61558 and
Magnetec Cool Blue nanocrystalline cores from MH&W International are intended for use as common mode chokes. The cores provide a range of permeability of 25,000-90,000 at 10 KHz, and a saturation flux density of 1,200 mT. The smallest core for high power motor applications has an outside diameter of 63 mm and inside diameter of 50 mm. The largest core has a 500 mm OD and 450 mm ID
Wacker Chemie announced Thursday that it will build a $1 billion plant with 500 jobs in southeastern Tennessee to produce hyperpure polycrystalline silicon, a product used to make solar panels and semiconductors. Company executives, Gov. Phil Bredesen and economic development officials said the company has purchased a 550-acre site about 30 miles northeast of Chattanooga.
Pushing the envelope of Albert Einstein's "spooky action at a distance," known as entanglement, researchers at the Joint Quantum Institute (JQI) of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Maryland have demonstrated a "quantum buffer," a technique that could be used to control the data flow inside a quantum computer. Quantum computers could potentially speed up or expand
Intended to enhance the workflow for digital line sensors such as the ADS80, Leica XPro line sensor workflow software by Leica Geosystems and North West Geomatics covers the process from data download to image generation.
