Hand packing a wheel bearing with grease is time consuming because old grease must first be removed. There is no guarantee of thorough packing. It's also messy and wasteful. An alternative is using a device that fully encloses the bearing, with another device to force grease through the bearing at high pressure. This method requires set-up time, and is limited to the type of grease stored in the pumping device.
To minimize hand contact with grease, and provide a faster and cleaner method, this device uses three components:
A bearing stand to support the bearing
A cylinder with loading head (dispenser) that draws and dispenses new grease
A plunger that forces new grease through the bearing, dispelling old grease and replacing it with new grease simultaneously
The simple and inexpensive design is patented and could be made of metals or plastics.

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.
