Mark Thoren and Jim Williams needed to test the temperature compensation scheme of a circuit they were designing. The lab had several temperature chambers, but they were always in use. In frustration, Jim grabbed a brand new toaster and plopped it down on Mark's desk, saying, "This will do." Not quite. The hysteresis of the oven's thermostat was 10C — too crude to measure the circuit. Mark and Jim scrounged about and found an auto-tuning temperature controller, some solid-state relays and a shiny platinum RTD probe. After some minor rewiring they had a test chamber, more than adequate and better than most of the "real" chambers that were never available when needed.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
