Mobile Measuring Systems Deliver Best-In-Class Precision
Powered by DC micro-drives, a miniature, vibration-free measuring device that detects even the smallest irregularities has been created. Measuring devices for surface roughness measurement are usually rather large. In the past, the measuring object has always been brought to the measuring device rather than vice versa. In order to give this micro device best-in-class precision, vibration resistance, and portability, FAULHABER DC Motors from MICROMO were used.

Ford develops totally new sheet metal 3D forming process

How do you stamp out prototype sheet metal parts without "stamping" them in a single blow -- and without a die to boot? No, it's not a Zen riddle. It's a question that Ford engineers have been working on for a while, and now they think they have the answer.

FEA aids Deepwater Horizon failure forensics
On the evening of April 20, 2010, Deepwater Horizon suffered a blowout while drilling in the Macondo Prospect, an area in the Gulf of Mexico 40 miles off the southeast coast of Louisiana. The platform caught fire, and two days later, it sank. Eleven crewmen were killed. The spewing oil caused the largest offshore oil spill in U.S. history. In this article, engineers use Abaqus Finite Element Analysis to do some of the detective work concerning what went so terribly wrong with the rig's blowout preventer stack.

'Magic powder' is secret to inflatable space antenna design for CubeSats
Researchers at MIT have come up with an inflatable antenna design that may significantly increase the communication range of small satellites called CubeSats, enabling them to travel much farther in the solar system. But the real story is in the "magic powder" used to inflate the device.

Jaguar conquers America's Snowbelt with 4WD

For Jaguar, competing across the broad swathe of "Snowbelt" states in North America meant equipping its XJ and XF luxury sedans with four-wheel drive -- something totally new. Time was short, so international automotive design expert Ricardo was summoned to help. Jesse Crosse reports.

Johnson Controls has simple 'aha' moment in seat-adjustment design

When engineers at Johnson Controls decided to try to simplify seat adjustment in small and compact vehicles, they didn't look at adding an extra dial, a new button, or even a better lever. They looked at how drivers of different heights adjusted their seats, and that put them on the right track. Literally.

Plastic parts with no molds required

How often have you wondered what life would be like without having to worry about paying tooling charge after tooling charge for products in early development? The "No Molds Required" (NMR) manufacturing technology from Envision Plastics & Design could be your answer. This unique production process harmonizes a combination of sheet metal fabrication and woodworking practices to produce plastic parts used for enclosures, panels and shrouds, brackets and shields, medical-based products, and more.

ID/OD retaining ring lock

Spirolox Retaining Rings, available only from Smalley, can operate in an internal and an external groove at the same time! Spiral-type retaining rings have many great benefits for the ID/OD Lock, some of which include concealed fastening, no required assembly tooling, and a 360-degree rotational capacity.

Brighter, stronger, cooler flip-chip LEDs

TitanBrite Wireless Bonded LEDs from Lumex feature "flip chips" that are up to 15 percent brighter than any others in the market. In addition to the standard 3-W and 6-W LEDs, Lumex's TitanBrite Wireless Bonded LED is also available in 9 W. Wireless bonded LED technology, also referred to as "flip chip," offers several key performance benefits over traditional surface-mount technology (SMT) LEDs, including enhanced durability, enhanced heat dissipation, and superior light performance. A flip-chip LED is up to 15 percent brighter, 5x stronger, and 25 percent cooler than alternative technologies. Applications include: automotive interiors, appliance backlighting, industrial control lighting, medical lighting, signage, construction, and military.

Mini rotary actuator has highest torque and power output

New Scale Technologies has demonstrated a miniature rotary actuator module (M3-R) with torque of 0.17 Nm and speeds of more than 400 degrees per second in a compact, 60-mm-diameter by 8-mm-thick design. Resulting from the successful completion of a Phase 1 SBIR project for the U.S. Navy, the non-inductive rotary actuator module delivers higher power output in a smaller footprint than electromagnetic pancake motors or other piezoelectric actuators. Applications include guided munitions and missile systems, MRI-compatible medical devices, unmanned aerial vehicle (UAV) controls, gimbal systems, and computer equipment.

TI 20-W stereo speaker amplifiers reduce BOM cost for mid-power audio applications

Texas Instruments has introduced a new family of four digital-input, closed-loop I2S amplifiers for mid-power stereo audio applications including TVs, soundbars, portable docking stations, Bluetooth speakers, and aftermarket automotive audio products. The TAS5760xx devices feature high switching frequency, allowing designers to use smaller output filter components to reduce overall solution size and bill of materials (BOM) cost. They stream 20-W continuous power per channel without a heatsink and deliver the industry's best performance specifications, including THD+N of 0.03 percent at 1 W, crosstalk of -92 dB, and 66-uV idle channel noise.

'Impossible dream' achieved in Sikorsky human-powered helicopter challenge

After 33 years of trying, a team has finally won the American Helicopter Society (AHS) Igor I. Sikorsky Human-Powered Helicopter Competition -- and its $250,000 prize! The challenge: fly a human-powered helicopter above 3 m and hover for more than 60 sec in a 10-m x 10-m space. Canadian team AeroVelo Inc., comprised largely of students at the University of Toronto, flew its extremely novel (and huge!) ATLAS pedal-powered helicopter for 64 sec June 13. A single pilot powered the craft, which featured four, nearly 70-ft rotors attached to a 115-lb carbon-tube and polymer frame. The AHS first issued the human-powered flight challenge in 1980, with an initial prize of $10,000. More than 20 human-powered helicopters have been designed and built since the competition began, though only a handful have gotten off the ground. Officials from AHS International verified the flight data over several weeks and concluded that it met all of the criteria necessary to win the competition. Sikorsky increased the prize to a quarter-million dollars in May 2009. Who would have guessed that this would be the winning design? Incredible.

Making M.C. Escher's drawings come to life with 3D printing
Is it possible to create 3D objects that represent some of M.C. Escher's head-scratching 2D drawings? Well that is what Prof. Gershon Elber of Israel's Technion's Faculty of Computer Science has done. See the impossible come to life using an Objet 3D printer. Super cool.
