This past Friday brought news of a handful of indictments of elections officials in Kentucky who are alleged to have rigged elections in 2002, 2004, and 2006 by changing votes in electronic voting machines. Remarkably, the vote manipulation technique here was essentially an exploit of a simple UI design flaw, and involved no computer skills at all on the part of the alleged perpetrators.
Carbon-nanotube ribbons developed by researchers at the University of Texas at Dallas are stronger than steel, as stretchy as rubber, and as light as air. The ribbons, which are made of long, entangled 11-nanometer-thick nanotubes, can stretch to more than three times their normal width but are stiffer and stronger than steel or Mylar lengthways.
A high-temperature vibration monitoring system, model 5334 from Dytran Instruments, can handle up to 900°F. Operating from a constant current 2-wire (IEPE) power unit, the system consists of a high temperature charge mode accelerometer and an in-line miniature differential charge amplifier. The accelerometer is connected to the input of the charge amplifier via an 18-inch long hard line cable
The AS1332-34 family of step down DC-DC regulators from austriamicrosystems achieves 97 percent peak and 94 percent average efficiency. The three devices in the family deliver up to 650 mA from an input voltage range of 2.7 V to 5.5 V. Output varies between 1.3 V to 3.16 V. Other features include: 2-MHz fixed switching frequency
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
The Keithley Test Environment Interactive (KTEI) V7.2 upgrade for the Model 4200-SCS Semiconductor Characterization System includes nine new solar cell test libraries, an expanded frequency range for the system’s Capacitance-Voltage (C-V) measurement capability, and support for the company’s new nine-slot Model 4200-SCS instrument chassis.
Based on Intel’s Penryn family of Core 2 Duo Mobile processors, Stealth Computer’s Model LPC-625F is a rugged, 7.9" x 7.9" x 2.4" fanless computer for industrial and mission-critical applications with an extruded-aluminum chassis that acts as a heat sink.
With a typical phase noise of -102 dBc/Hz at 10-KHz offset, Crystek's CVCO55CC-2400-2569 VCO (Voltage Controlled Oscillator) operates from 2400 MHz to 2569 MHz with a control voltage range from 0.5 V to 4.5 V.
PLX Technology, Inc. announced four new high PCIe switches targeting servers, enterprise storage, control planes, and ultra-gaming, while featuring the highest PCIe switch lane counts in the industry, according to the company. The switch family includes 96-lane and 80-lane options, as well as x16 support for designers requiring
Valpey Fisher Corporation introduced its VFTX210 TCXO, providing low jitter and phase noise for wide band ADC's and DDS architectures, radar systems, point to point radios, and wireless communication systems. The VFTX210 TCXO is capable of providing a sine wave output frequency up to 1.0 GHz with jitter of <0.3 ps. The temperature stability is < 1.0 ppm over a
Moving forward, what technology will dominate energy harvesting?
Offering over 40 percent space savings compared to a discrete implementation, the TinyBuck FAN21SV06 6A synchronous Buck Regulator from Fairchild Semiconductor incorporates a controller, driver and optimized power MOSFETs in a compact 5mm x 6mm MLP footprint.
Microsoft Corp. released a new version of Internet Explorer Thursday, adding features meant to speed up common Web surfing tasks and bringing the browser's security measures in line with those of major competitors.
Consisting of 3 standard models providing outputs of 12, 24, or 48 VDC, the ARFS-150 Series of 150-W open-frame switching power supplies from Aras Power Technologies is provided in a package measuring 3.0” x 5.0” x 1.08”. The universal-input supplies include active PFC and ORing diodes for 1+1 redundant operation.
Using an 8-pole segmented-stator design for increased energy density and efficiency, the SmartMotorsT SM3416DT-PLS2 integrated servo motor from Animatics packs greater than 900 Watts of peak power, over 1 HP, into the cube-shaped NEMA Size 34 package.
