Productive Product: It was good enough for Columbus, Magellan, and Ellison, but is wind power -- the sail -- better in some cases than modern engines for oceanic cargo ships? A few companies are voting affirmatively. A blogger for Network World writes, "A kite the size of a football field will provide most of the power for a German
Advanced Analogic Technologies, Inc. announced the AAT2504, an adjustable 3-channel regulator that combines a step-down converter with two low dropout linear regulators (LDOs). Targeted at mobile devices with rapidly changing feature sets, it allows designers to extend system functionality and still benefit from power management integration. The step-down converter delivers up to 800 mA of output current and supports an input range of 2.7V to 5.5V
Productive Product: What if nuclear power were mass-produced in portable battery-like containers? That's the mission of Hyperion Power Generation, a start-up based on the research of Los Alamos National Labs scientist Otis Peterson. The bathtub-sized device with no moving parts could power 25,000 homes for five years, and Hyperion is poised to build 4,000 around
Energy News: "Making a Business of Energy Efficiency: Sustainable Business Models for Utilities" is the topic of next month's Edison Electric Institute meeting in Washington. The EEI is an electric company association and the agenda focuses on money -- not customers, the environment, or technology. There is an interesting
Minmax's AQF-30 is a 30W series of AC/DC power modules that have universal input range of 85V AC to 265V AC with single, dual and triple output voltages. The modules boast efficiencies up to 80 percent and are EMI Compliant with EN55022 Class B and FCC part 15, level B and EMC Compliant With EN61000 (-2, -3, -4). The series is suitable for a variety of applications
Op-Ed: Ah, winter: the holidays, the Superbowl, snow sledding and nasty weather, the hassle of decorating, and what to get the engineer who has everything? We here at ECN figure the answer to that last point -- high-tech for the holidays -- is best derived from you, the readers.
ITT Electronic Components developed a Micro-D connector with desirable attenuation. Designated the TMDMP filter, the connector utilizes an internal filter design, providing the density needed to accommodate the ferrite tubes necessary for Pi filtering in military and aerospace applications. The TMDMP filter connector is suitable for integrated avionics and electronic warfare
My first experience with a relay came about when a friend found a radiosonde -- a small balloon-borne weather instrument -- in the woods behind his house. My friend Ben wanted the parachute, so I got the electronics. As a kid of 11 or 12, the circuitry didn't mean much, but it included a simple relay I experimented with.
Productive Product: Maxwell Technologies is working with China's Lishen Battery to design hybrid lithium-ultracapacitor products, Maxwell officials said today. Immediately, Lishen will start making lithium cells adjacent to ultracapacitors in the same package, while preparing to merge lithium with ultracapacitors in individual hybrid cells by summer 2009.
Maxim Integrated Products introduced the DS4-XO series of crystal oscillators that support frequency operation from 75 MHz to 622.08 MHz. These miniature crystal oscillators are available in a 5 mm x 3.2 mm package and provide jitter performance of less than 1 psRMS (12 kHz to 20 MHz) over the -40°C to +85°C extended temperature range. Manufactured using fundamental AT-cut crystal technology with no overtone,
Crystek's CVCO55CC-2778-2945 VCO operates from 2778 MHz to 2945 MHz with a control voltage range of 0.1V to 16V. This VCO features a typical phase noise of -110 dBc/Hz @ 10KHz offset and has excellent linearity. It is packaged in the industry standard 0.5" × 0.5" SMD package. Input voltage is 8.0 V, with a max current consumption of 40 mA. Pulling and Pushing are minimized to 5.00 MHz and 2.00 MHz/V
Productive Product: UCLA researchers are able to print batteries on flexible circuits by using nanotube inks, NewScientist reports. There are similar projects, such as at Rensselaer Polytechnic Institute, and it's not immediately clear how the UCLA project differs. However, NewScientist explains
Productive Product: I wrote about energy harvesting a few times before, and now there's a practical application: power for field soldiers. The Seattle Post-Intelligencer reported on M2E Power, a Boise, Idaho start-up that says it has a (no pun intended) more efficient way to perform energy harvesting -- the general idea of energy harvesting from mechanical movements traditionally does work but hasn't been worth the trouble.
CIT Relay & Switch announces the BST and BSP Series toggle and pushbutton switch series, providing design engineers versatile, multiple function toggle and momentary pushbutton switches for use in a variety of applications. Both offer a wide variety of termination options. The BST toggle is available with numerous actuator lengths and optional gold contacts. The BSP pushbutton features a snap-in mounting option. Both series offer
Electrostatic discharge (ESD) occurs when objects -- including people, furniture, machines, integrated circuits or electrical cables -- become charged and discharged. Electrostatic charging brings objects to surprisingly high potentials of many thousands of volts in ordinary home or office environments. ESD produces currents which can have rise times less than a nanosecond, peak currents of dozens of Amps and durations that can last from tens to hundreds of nanoseconds. Unless ESD robustness is included during design, these current levels can damage electrical components and upset or damage electrical systems from cell phones to computers.
