Where demanding rotary movements are required at very high loads, igus cable carriers with reverse bending radii
(RBR) are usually used. With these, circular movements up to 540 degrees are
possible. However, the installation spaces involved are usually large in terms
of depth and width. As a medium-sized solution in the igus' circular cable
carrier range, a second possibility is the TwisterChain cable carrier. This
sturdy, smooth-running cable carrier was designed for one-and-a-half complete
rotations, coupled with high dynamics. The system's diameter is takes up more
height, less width and comes nearer to the axis of rotation.
Where installation space is extremely limited, on the other hand, a different,
compact and very easy to fill micro-solution is required. Following months of
development work, the igus design engineers have presented such a solution.
New TwisterBand TB30 makes rapid rotating movements possible up to 3,000
degrees and depends only on the belt length or design height in the axis of
The polymer cable carrier is lightweight and easy to use. The
injection-molded chain has easy access links allowing users to simply press in
cables and hoses through split openings.
The design is modular and extremely flexible and does not have to be
customized to individual customer specifications. One type is already
available, with further larger and smaller versions planned.
Applications for the slim design circular chain system are mainly in
robotics supplying one and six axes in special machine construction, handling,
lifting and assembly equipment and test jigs.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
