Still Working On My Solar-Panel ROI
By Don Tuite, Analog/Power Editor

“The meter’s running backwards!”

I wrote that line in August 2006, quoting my wife Vicky, who was entranced by the most visible manifestation of what our just completed rooftop grid-connected solar system was achieving (“A Solar Story,” ED Online 13242). While that column covered the technical details of its installation, this story is about the economic advantages we’ve seen since then.

The Power Of The Portfolio Can Maximize Software Development
By Martin Bakal and Charles Krueger

Most companies target their customers' needs by creating a product line rather than a single product. Yet developing software for the multiple products in these lines can be challenging, hindering your company's opportunities. New software development methods and tools known as software product-line engineering, though, are emerging to give your the competitive advantage you need.

Create A 250-MHz Bandwidth Digital Potentiometer For Video Level Control
By Oleg Ayranov and Georgi Georgiev, Wey Elektronik AG

A circuit used to control the level of a video signal should have a 3-dB cutoff frequency of greater than 5 MHz for a television application or 100 MHz for a monitor application. CMOS-based digital potentiometers typically cannot be used as video devices because their frequency responses barely exceed 1 MHz. For such applications, a good choice would be a variable-gain amplifier (VGA) with analog or digital gain control.

Multichannel Transceiver Offers 5-km Range

With a 500-mW (+27 dBm) RF output power and a receiver sensitivity of –118 dBm (for 12 dB SINAD), the BHX2 multichannel narrowband transceiver sports a range of up to 5 km. Standard operating frequency is 458.5 to 459.1 MHz, but factory-tuned custom versions can cover any 5-MHz switching band between 420 and 480 MHz.

Nanoparticles in Medical Applications

Professor Michael McHenry of Carnegie Mellon University is investigating the efficient point source heating of metal nanoparticles for thermoablative cancer therapies. These nanoparticles can be heated in a radiofrequency coil to kill tumor cells. This work is being done in collaboration with Materials Science and Engineering's (MSE) Professor Michael Bockstaller, as well as Dr. Preet Chaudhary of the Hillman Cancer Research Center at the University of Pittsburgh Medical Center (UPMC). The team is focused on tagging and changing the shape of tissue scaffolds, in collaboration with the McGowan Tissue Engineering Center at UPMC, MSE alumnus Dr. Tom Gilbert, and his colleague Dr. Steve Badylak.
