| 50 years ago: Armstrong survives training crash | |
On May 6, 1968, astronaut Neil A. Armstrong, then assigned as back-up commander for the Apollo 9 mission, took off on a simulated lunar landing mission in Lunar Landing Research Vehicle #1 at Ellington Air Force in Houston. He had been airborne about 5 minutes when he suddenly lost control of the first pure fly-by-wire aircraft.

'Super window' could save $10 billion annually in energy costs About $20 billion worth of energy leaks out of windows in the United States each winter -- and that's with double-paned insulating windows installed on a majority of buildings. Berkeley Lab is now working with manufacturers to bring to market a "super window" that is at least twice as insulating as 99 percent of the windows for sale today and will be ready to achieve mass-market status.

Wheels: After years of trying, teen electrifies 1980 Celica Adam Lansing got the idea to convert a gas car to electric after watching his older brother ask his parents for gas money. It took him a total of six years of frustration and some huge triumphs, but now he's turned an old, engine-less Toyota into something unique: A 130-mile range electric vehicle powered by 94 lithium iron phosphate batteries.

Mike Likes: New 22-mm brushless servo motor packs a punch MICROMO has launched the brand new FAULHABER 2264 BP4 series brushless dc servo motor, which is ideally suited for handheld tools and devices such as motorized surgical instruments, grippers and robotics, advanced prosthetics, aerospace applications, and even for electric pruning shears and motorized screwdrivers. At 22 mm in diameter, 64 mm in length, and weighing only 140 grams, the 2264 BP4 series delivers 59 mNm of continuous torque and reaches speeds up to 34,500 rpm. These impressive power and performance characteristics are possible due to a new segmented winding of the coil, which also improves the overall efficiency of the motor.

Engineer's Toolbox: What's the difference between 17-4PH and 316L stainless steel for pressure sensors? Stainless steel pressure sensors and transducers are most commonly manufactured from either 316L or 17-4 PH. Both offer good material strength and good elasticity, but there are key differences that can have significant impacts on which material you should choose for your application.

Great Resources: Selective Laser Sintering (SLS) Design Guide Xometry is full of great resources for designers -- and great manufacturing services. Selective Laser Sintering (SLS) is an additive manufacturing process that can efficiently produce durable nylon end-use parts and prototypes. Using SLS has a number of benefits, including the ability to manufacture high-precision and complex parts without the need for tooling or molds. It also enables the production of parts that would be difficult or impossible to create any other way. Learn how to design your products to achieve the best SLS results.

Sony releasing 0.5-type OLED microdisplay with top-of-class UXGA resolution Sony Corporation recently announced the upcoming release of the ECX339A OLED Microdisplay featuring UXGA (1,600 x 1,200 resolution), the highest in class for a 0.5-type. This product achieves the world's smallest pixel pitch of 6.3?m by leveraging Sony's OLED display technology and miniaturization technology, enabling a resolution 1.6x higher than the previous model. By employing a new drive circuit design that operates on half the voltage of the previous model, the new product achieves the same level of low-power operation as its predecessor but with much higher resolution.

New telescopic pillars for medical equipment support heavier loads SKF CPMT telescopic pillars from SKF Motion Technologies for integration into surgical tables, procedure chairs, and similar medical equipment are complete plug-and-play systems that provide OEM designers with ideal technologies to equip healthcare facilities with reliable, safe, and virtually maintenance-free vertical motion solutions. CPMT telescopic pillars combine a low retracted height (320 mm or 12.6 in.) with a high stroke range (up to 600 mm or 23.6 in.) to improve accessibility for patients without compromising the extended height necessary for procedures. Other capabilities include a high load-carrying capacity (up to 6,000 N or 1,350 lb), as well as fast positioning speeds and the ability to access pre-set positions for overall clinical efficiencies.

| Intro to different types of piezo actuators/motors | |
The term "piezo" is derived from the Greek word for pressure. In 1880, Jacques and Pierre Curie discovered that an electric potential could be generated by applying pressure to quartz crystals; they named this phenomenon the "piezo effect." Later, they ascertained that when exposed to an electric potential, piezoelectric materials change shape. This they named the "inverse piezo effect." But what can you do with it? Physik Instrumente (PI) runs through the basics when applying the effect to motion drives, including stack actuators, flexure guided actuators, bimorph bender actuators, piezo motors, and more.
