The SHF-2A-GR high-accuracy harmonic-drive gear reducer features a large hollow shaft and can be incorporated into a custom housing to achieve an optimum package size. The design is both axially shorter and lower in weight, and uses the "S" tooth profile. Gear reduction ratios of 50:1 through 160:1 are available in a single stage. The large hollow shaft enables the user to pass shafting, wire bundles, or other components directly through the gearing's center.

A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
