Going ‘Digital’ Simplifies Medical Device Inspection

At various times throughout the manufacturing process, medical device and orthopaedic implant manufacturers need to carry out a wide range of inspections and measurements of the parts that they produce. Operators in the orthopaedic industry, for example, may check hip stems against a template many times during the grinding and polishing process. Like many manufacturers across a wide range of industries, they have traditionally used optical comparators to check parts directly on the shop floor.

Reducing Design Time for Linear Motion Systems

Design time can be reduced while ensuring durability and high performance. Reducing design time is critical in engineering because the result is lower costs and faster time to market. Design time often includes a number of non-value-added activities such as re-design, over-design, or scope creep that can be minimized by thoroughly understanding all of the application criteria and verifying calculations and analysis via parametric testing of components, modules, and full assemblies with data acquisition equipment, and proving out projected performance results with testing.

Expanding the Use of Smart Operator Panels

The evolution of operator interfaces has moved quite far beyond the pushbutton. Once, the intelligence resided in the operator’s brain, and considerable experience and training were required to operate any complex piece of machinery or process. The evolution of the operator panel is actually two parallel evolutionary tracks. First is the movement of that intelligence from the operator’s brain into the operator panel itself. So, we now refer to them as “smart operator panels.” The other track is how the evolution of the operator panel tracks Moore’s Law, making them more powerful and less expensive.

Silicon Block Inspection with SWIR Imaging

In a world where oil production is declining, and where both nuclear energy plant and spent-fuel storage safety have proven to be inadequate, there is increased pressure on solar power generation to fill the gap. In response to the increased demands for energy, the photovoltaic manufacturing industry has focused on two primary objectives: driving down the cost of solar panels and increasing panel efficiency.

New Video Documents Three-Year Trek by Mars Rover

A new video compiles 309 images taken by NASA’s Mars Exploration Rover Opportunity, providing an historic record of a three-year trek that totaled about 13 miles across a Martian plain pocked with smaller craters. While Opportunity was traveling from Victoria crater to Endeavour crater, between September 2008 and August 2011, the rover team took an end-of-drive image on each Martian day that included a drive. The video featuring the end-of-drive images shows the rim of Endeavour becoming visible on the horizon partway through the journey and growing larger as Opportunity neared that goal. The drive included detours, as Opportunity went around large expanses of treacherous terrain along the way.
