A hybrid-lighting fixture based on simulating a typical fluorescent-light fixture containing four 40W tubes has two of the tubes replaced by diffusers. The hollow diffusers have their inner surface covered with prism-like bumps that refract the light traveling down the tube into the wall, illuminating the room.
Optical light guides route sunlight into the diffusers. Illumination sensors in the fixture monitor room light level. In place of the conventional ballast is an electronics package with an active solid-state controller. This varies current and voltage to the fluorescent tubes to produce a constant total-light level to the sensor setting. If the fluorescent tubes have sufficient capacity to illuminate the room fully when no sunlight is available, the light level will always be the same to the occupant.
A next-generation guided ammunition system for intercepting enemy fire that Lockheed Martin is developing for the Army has hit its targets in an initial series of tests by the company.
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.
