Apple eyes glues for notebook construction
Reports last month of a patent filed by Apple Computer, Inc. have many in Silicon Valley buzzing. The patent, innocuously titled
"Computer enclosure," paints a picture of the future of portable computing devices through the use of structural and electrical adhesives. In the abstract of the patent, inventors Michael Kriege and Dan Hong describe a structurally bonded enclosure. The project takes a turn into Skunk Works territory, however, with the additional claim of an electrically bonded device to form a
"singular integrated conductive member." Read the full article

Preform elastomers key to latest electronics protection
LORD Corporation, a global supplier of thermal management materials, adhesives, coatings, and encapsulants, has provided a two-component silicone elastomer solution that enables a new oil field down-hole technology to protect mission-critical electronic components from damage due to heat, shock, and vibration.
"Even specially designed electronics can have a meltdown when exposed to extremely high temperatures," says Lauren Groth,
president of Ultimate Solutions, the case's
developer. "And when you have sensitive electronics,
it often doesn't take much energy in the form of
shock or external vibration to cause damage." Read the full article
NASA shuttle engine upgrades focus on turbomachinery health monitoring
While much of the coverage for the space shuttle Atlantis STS-117 mission since its June 8, 2007 launch has concentrated on
its peeled-back thermal blanket and problems at the
International Space Station, a major main engine computer upgrade developed by NASA's Marshall Space Flight Center prior to the launch has received little fanfare. The Advanced Health Management System aims to provide new monitoring and insight into the performance of the two most critical components of the space shuttle main engine: the high-pressure fuel turbopump and the high-pressure oxidizer turbopump.

Inexpensive "nanoglue" can bond nearly anything together
Researchers at Rensselaer Polytechnic Institute have developed a new method to bond materials that don't normally stick together. The team’s adhesive, which is based on self-assembling nanoscale chains, could impact everything from next-generation computer chip manufacturing to energy production. The nanoglue is inexpensive to make and can withstand temperatures far higher than what was previously envisioned. In fact, the adhesive’s molecular bonds strengthen when exposed to heat.

Wheels: Closing velocity sensor begs the question,
"Who’s driving?"
Continental Automotive Systems has developed an optical sensor that they say can help a driver reduce the severity
of — or completely avoid — collisions when traveling at speeds less than 25 mph. The closing velocity sensor is the latest component in the company's Active Passive Integration Approach (APIA) vehicle safety network. As a result of a perceived unavoidable accident, the APIA will, among other things, react automatically to tighten seatbelts, close windows, optimally position seats, and put the brakes on alert mode.
