White Paper: MIL-STD-1553 IP Cores - An Emerging Technology

The MIL-STD-1553 serial data bus is widely used for control purposes in avionics, aircraft and space systems. Forty years since its release, 1553 is evolving from traditional integrated circuits (IC) to intellectual property (IP) cores integrated with Field Programmable Gate Array (FPGA) logic. The history of MIL-STD-1553, the advantages and requirements of 1553 IP cores compared to standard ICs, and IP core design best practices are discussed in this white paper.

White Paper: Computer System Design for Critical Applications

"Industrial computer" is a widely used term that unfortunately can be quite ambiguous, often applied to computers that have little real advantage over commercial PCs but may outwardly appear "rugged". However, there are many applications that need a computer system that is truly built to a higher standard for reasons that include:

Laser-Induced Damage to Large Core Optical Fiber by High Peak Power Laser

In this paper we present a study of laser damage to large core multimode glass optical fibers by high peak laser power of up to 175 kW. Fibers samples prepared with polymer coatings having different refractive indices were tested in a two point bend tester while transmitting laser light. The peak power used in the experiment clearly differentiated the performance among the samples. A polymer coating having lower refractive index significantly improves the fiber resistance to bending while transmitting laser. This observation provides important insight into the damage mechanism for this particular failure mode.
