MOTION CONTROL: Servometer®- PMG, LLC introduces a new and unique “atherm” temperature sensitive bellows assembly. These lightweight, extremely sensitive assemblies are thin-walled, electrodeposited nickel bellows soldered to custom end pieces filled with a working fluid (with a known coefficient of thermal expansion) and then sealed.
By sealing a specific volume of fluid within a Servometer electrodeposited nickel bellows, the volumetric thermal expansion characteristic of the fluid is transformed into a precise, measurable linear movement. This movement can be used as an actuator, or calibrated to be read as control data, and is completely reversible due to the extremely low hysteresis of the bellows material.
A Servometer atherm is presently being used in one defense application to compensate for the thermal growth of components within precision targeting devices. The response of the bellows ensures that the targeting image is not distorted by environmental changes in temperature from sub-zero to extreme desert heat conditions.
These athermalization bellows assemblies are designed, manufactured and assembled to the customers exacting specifications.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
