Robotic Vision Keeps an Assembly Plant at Home

A major manufacturer of electromechanical products had been operating six separate indexing assembly machines, each producing one of a family of more than 75 different products at about 40 parts per minute. The machines frequently sat idle as demand fluctuated for the various products. Labor expenses were high since each machine required a dedicated operator. The manufacturer considered moving the six machines and their entire production offshore to reduce labor expenses and save floor space at its European facility.

Wide-Area Surveillance Using HD LWIR Uncooled Sensors

The effectiveness of airborne search and rescue, navigation, and situational awareness tasks is predicated on the availability of high-resolution imagery that provides pilots with a clear picture and the widest possible field of view. While the human eye is extremely high resolution with an unmatched ability to detect high-spatial-frequency (HSF) objects across a wide field of regard, human vision can easily fatigue, is subject to environmental conditions, and is vastly degraded at night.

3D Printing Enables Customized Magnets

Polymer-bonded magnets are valuable for many sensor applications that require the production of unique and reproducible field profiles, not necessarily fields with the highest strength.

Oil Sheer Clutch Cuts Downtime for Metal Stamping Press

Replacing a mechanical clutch, the oil sheer technology supplies constant, reliable tension on the stock feeding a 400-ton press to deliver precision and repeatability.

In the metal stamping business, precision, repeatability, and uptime are key. But stamping accuracy suffers when improper tension on the coil feeders incorrectly supplies metal to the presses, resulting in off-spec parts and increased rejections. ART Technologies of Fairfield, OH, relies on an oil shear clutch brake to supply constant, reliable tension on the coil feeding to one of its 400-ton presses to produce the precision and repeatability it needs, with no downtime for maintenance or adjustment. When the plant is working 20 hours a day, that uptime is as critical as the tolerances it maintains.

Choosing a Light and Color Measurement System for LEDs

LED-based lighting and display systems are becoming increasingly popular due to their low cost, flexibility, and efficiency. Measuring the light and color output of LEDs is, therefore, becoming more important as their performance is compared to and evaluated against traditional technologies. In addition, inherent performance variations from device to device must be understood and controlled.

Miniature Camera Mimics Eagle's Eye

A tiny, 3D-printed “eagle-eye” camera developed at the University of Stuttgart in Germany mimics the vision of some of nature's sharpest predators. The “foveated” imaging system, named after the fovea part of the eye, provides a high central acuity that could support new applications in optical sensors, endoscopy, and surveillance drones.

Custom Brakes Meet the Challenges of Gearless Motor Elevators

Standard braking systems could not meet the difficult speed, energy, and dynamic torque constraints.

A manufacturer of low and high-rise elevators faced a challenge when customers began calling for a flexible elevator to meet the needs of the growing mid-rise, mixed-use building market. The global construction boom of mid-rise buildings can be attributed to several factors. Developers are more apt to build “short” because it requires less capital and the time to get permits approved is reduced considerably, especially in developing countries.
