Looking to paint the town red (or his buddies at any rate), Nathan Loden devised this simple device to detect if the paintballs are traveling at a safe speed (& 300 ft/sec). Consisting of sensor circuitry and a microcontroller with a three digit, seven segment display driver, it detects the presence or absence of a ball by measuring the amount of IR energy striking the sensor, causing a voltage swing detectable by the micro. A timer is set to overload if the number of instruction cycles exceeds a limit equal to 300 ft/sec, indicating safe shooting.
Plastic may not be the most beloved of materials to the more environmentally minded, but Plasti 2012 aimed to mold a different opinion of the material in people's minds.
The rare earth element market has become steadily more rational, and new sources coming online will continue to reduce costs. Still, it is unlikely that prices will drop to their former lows.
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.
