18 November 2002 | InformationWeek
by Aaron Ricadela
"Aspect-oriented programming is the product of more than a decade of research... It continues a trend in computer science of making software programs smaller and more manageable by sharing and reusing more code across their parts. 'It's the next generation of software engineering,' says John Seely Brown, director emeritus of Xerox PARC.
Xerox PARC: On The Money Trail
Famed Xerox Lab Looks for Profits in Research
11 November 2002 | ABC News
by Peter Dizikes
"After more than 30 years marked with famous breakthroughs that have shaped the high-tech world, PARC is at a new stage in its history. In January, Xerox...spun off the Palo Alto center to be a separate financial entity. That means PARC must now seek its own revenues through patents, licensing its technology and finding new high-tech backers."
Stressed Metal Nanosprings
Applications in interconnect and passive components
1 November 2002 | Advanced Packaging
by Christian Linder, David Fork, Christopher Chua, Koenraad Van Schuylenbergh, Celine VanderStraeten, Darko Plesa
"A critical area of microtechnology is the mechanical stress of thin films. Generally, the goal is to keep the stress as low as possible for providing durable and reliable film stacks. On the other hand, it is possible to make use of highly stressed thin films. In a joint effort, PARC and Unaxis Semiconductors developed processes for the stress engineering of metal films."
'PCs for peace' drive gains PARC support
24 October 2002 | Silicon Valley/San Jose Business Journal
"PARC has joined with the non-profit World Computer Exchange to help the world's poorest youth bridge the global divide in information, technology and understanding. PARC has donated 30 working computers toward 400 machines expected to be shipped to developing nations next month."

PARC Builds 3-D Structures on IC Substrates
10 October 2002 | EE Times UK
by Luke Collins
The PARC "process uses...sputtering to deposit films with a built-in stress gradient so that when they are patterned and released from their substrate, they curl into a designed radius of curvature. These shapes can be designed to curl up enough to create dense interconnects or to curl over in pairs to form inductor coils."
The Shape Of Bots To Come
7 October 2002 | Wired
by Kendra Mayfield
"PARC developed a modular robot...made up of a chain of simple hinge joints that can change from a serpentine shape into a leggy spider that can stride over rocks and bumpy terrain. Mark Yim, project leader for PARC's modular robotics team, said self-reconfiguring robots...are versatile, robust and could eventually be mass-produced at low cost but..."

Johan de Kleer, Manager of PARC's Systems and Practices Laboratory "talks about knowledge tracking, smart matter and other new developments in AI."
Wireless Networking Everywhere
3 September 2002 | PC Magazine
by Cade Metz
PARC "is investigating how two unacquainted computing devices can connect over a wireless network and teach each other how to share information. 'Just as we have a modular way to program software languages, we've now produced a modular way to create a world of computation around you,' says Mark Bernstein, the director of PARC."
Pop-Up Radio Parts
1 September 2002 | Technology Review
by David Cameron
To squeeze an entire radio onto a silicon microchip, chip makers will "require high-performance, microscale versions of all the parts that go into conventional radios [including] tiny inductor coils. But 'high-quality coils have been difficult to integrate directly onto a chip,' says PARC physicist David Fork. PARC's solution: coils that 'pop up' out of the chip's silicon surface."
Weaving A Web Of Ideas
Engines that search for meaning rather than words will make the Web more manageable
1 September 2002 | IEEE Spectrum
by Steven M. Cherry
PARC's scatter/gather method "takes a random collection of documents and gathers them into clusters, each denoted by a single topic word... The user picks several of the clusters, and the software rescatters and reclusters them... 'The user...can get a good sense of what's in a million documents in about 15 minutes' says PARC's Stu Card."
Just One Word - Plastics
Organic semiconductors could put cheap circuits everywhere and make flexible displays a reality
1 September 2002 | IEEE Spectrum
by Samuel K. Moore
"While industry insiders cannot predict whether polymers or small molecules will rule the organic electronics universe in the end, all agree that the deciding factor will be manufacturing costs. Either way circuits will be cheap when future electronics price battles hinge on the technologies that make junk mail and potato chip bags, notes Raj Apte [who] heads up organics research at PARC."
Bridging the Circuit Gap
14 August 2002 | Red Herring
by Lee Bruno
PARC "researchers have developed one approach to bridging the electrical connection gap...an on-chip, out-of-plane inductor, or micro-spring for short [which] self-assemble on the chip. The researchers claim that these micro-springs offer performance gains that are 50 to 100 percent higher than alternative technologies, at a comparable cost."
Wireless (In)Security: Are Your Networks Snoop-Proof?
Is wireless security an oxymoron? It doesn't have to be, with the right company policies and strategy to minimize exposure to hackers, or just plain folks.
19 July 2002 | CIO Insight
by Gary Bolles
"PARC's [Diana] Smetters says it's easy for a corporate spy seeking to 'sniff' the laptop of a competitor...using a wireless card and 'sniffer' program...if no wireless security software is in place. 'People are going to take their laptops, and with wireless they're going to be moving in and out of your firewall in a much more dynamic way...'"
Eavesdropping Gets People Talking
10 July 2002 | Technology Research News
by Kimberly Patch
"Researchers from PARC have made using audio devices a much more social activity by enabling eavesdropping among companions who are wearing headphones in close proximity... [They] are aiming for a 'conversationally compatible' computer interface that will make the information retrieval abilities of computers available in distinctly human social contexts."
Looking At Display Devices
1 July 2002 | Architectural Record
by Tomas Hernandez, Jr.
PARC has "been developing something called 'focus-plus-context screens,' devices that impose a low-resolution, rear-screen-projected image over a high-resolution image produced by a flat-panel monitor. These devices will allow users to see one area of an image in detail, while still allowing them to view it in its overall context."

PARC Raises Q Factor On Chips
12 June 2002 | Electronics Weekly
by Harry Yeates
"PARC claims the design gives Q factors on semiconductors 50-100 percent higher than current technologies, and can be batch fabricated using standard processing. Applications could include cell phones, TV tuners, wireless local networks and other RF ICs. Listed Q values are over 70 at 1GHz on insulators, and over 40 at 1GHz on standard CMOS. Solenoid inductances are 1-50nH."

by Lyle Kantrovich
PARC's experimental browser 'Popout Prism' "...provides an enhanced document overview alongside the web page that the user is browsing. The user can enter specific keywords they're looking for, and Prism creates large colorful boxes with the keywords in them ('popouts') wherever those keywords exist in the web page."
PARC's Mark Yim shows off his robots, which reassemble themselves to slink like snakes, roll like wheels or scamper like lizards.
1 May 2002 | Technology Review
by Wade Roush
"To Yim, these..prototypes are early steps toward ...machines that adapt to new environments...by altering not simply their behavior but their very anatomy. 'Their ability to morph from shape to shape makes them ideal for unstructured situations, like search and rescue in bombed or earthquake-damaged buildings.'"
US firms grow UV LEDs on AlN
30 April 2002 | Optics.org
"Researchers at PARC and Crystal IS, a substrate supplier, have demonstrated what they claim is the first UV LED grown on a single-crystal aluminium nitride (AlN) substrate. According to PARC's Michael Kneissl, the growth technique used reduces the RMS roughness of the surface from 0.83 to 0.38 nm prior to deposition of a graded AlGaN:Si buffer."
