A movable sunshade on the roof of the Milwaukee Art Museum consists of a pair of wing-like structures, each made up of 36 steel ribs ranging in length from 24 to 105 ft. The ribs are mounted on two rotating steel shafts, in turn connected to the pavilion's spine. To open and close the sunshade, 22 hydraulic cylinders (11 on each side) stroke simultaneously. The cranks swing a 90-degree. arc to open the wings in 3.5 minutes. Engineers equipped the building with two separate ultrasonic wind sensors to monitor velocity and direction. If wind speed exceeds 23 mph for three seconds or longer, the control system automatically closes the wings. Similarly, a lightning sensor is installed to predict imminent lightning strikes. The power unit consists of two identical pump sets. Each 30-hp motor drives a tandem axial-piston pump. One pump of each tandem set powers the north wing, the other powers the south wing. This circuit can move both wings even if one motor/pump group is out of service.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
