Insufficient contrast is a very subtle failure mode indeed. The system goes from functioning to intermittant to failed and nothing shows up as the cause. Hartridge has a similar problem with the linear encoders in their fuel injector system teststands, except that it is dirt, not fading. The normal fix is a new encoder for about $450, and two hours wait, and hope the new encoder is in stock. My cheap fix was to clean the scale in the encoder with denatured alcohol and a soft lense wipe tissue. Materials cost is about ten cents and the labor time is about five minutes and no recalibration is needed. But the profit is less, so the customer gets the _____.
I guess in today's highly regulated environment, this temporary black pen fix would not be enough. In addition to solving the problem immediately, a root-cause countermeasure would also be needed to be performed by the equipment manufacturer so this problem would not occur again years later.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
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
