Simultaneous Ultra Fast Framing and Streak Imaging

The ability to record simultaneous framing images and streak images has long been a requirement in the research fields of detonation, electrical discharge, biomedical and many other applications. Early systems incorporating both framing and streak cameras used external beam splitting optics with light gathering limitations that required critical alignment of the external splitting optics. Later systems incorporated framing cameras and streak cameras, built into one mainframe, using available beam splitters. This allowed for simultaneous framing and streak, however, this type of beam splitter limited access to streak optics, and primarily limited the performance of the streak camera due to the smaller format streak tubes.

Using RFID to Protect System Firmware

Breeching the security of safety- or security-intensive products such as auto parts, set top boxes, military electronics, or smart batteries can be a lucrative business that is well worth the nominal investment required to create lookalike packaging and labeling, or to change the system firmware to allow unpaid access to licensed content. Because the counterfeiter does not incur any of the costs associated with product development, he quickly covers his capital investment at the expense of the authentic product manufacturer or service provider.

Sensor Technology Leads Manufacturing into Predictive Maintenance

Reactive, avoidable equipment repairs are a leading contributor to lost productivity in industrial manufacturing operations. Parts with an average selling price of just a few dollars can cost manufacturers many times that in repairs and unrealized revenue once they fail. In a worst-case scenario, undetected faults can cascade through the system, causing widespread damage and triggering major and expensive production outages.

Going Green in the Workplace with LEDs

In August 2007, Cree’s management made a bold decision to replace the existing fluorescent lighting technology at its Durham, NC facility with new energy-saving, environmentally friendly LED lighting technology. The group started with the company’s headquarters building, but eventually plans to replace more than 7,000 existing fluorescent light fixtures covering more than 800,000 square feet campus-wide. Phase one replaced 200 existing fixtures in 7,000 square feet of space in the visitor lobby, waiting areas and conference rooms. All the exterior parking lot lighting was also converted from high-pressure sodium to LED lighting. Both parts of phase one had to be completed by early November 2007, just 3 months later.
