White Papers: Using FPGAs to Improve Embedded Designs

Field Programmable Gate Arrays (FPGAs) are semiconductor devices that are programmed after manufacturing to accomplish application specific functionality. FPGAs experienced rapid technology advancement in the 1990s, and today are found in a vast variety of products ranging from simple consumer items to highly complex military systems.

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:

Windows CE Development for RISC Computers Made Easy

Windows CE (a.k.a. Windows Embedded Compact), originally released in 1996, can be an attractive alternative to the full Windows operating system offering system designers the ability to control power, size, and cost in a new product. For example, the runtime license cost of the CE operating system alone can save as much as $150 over the license cost for standard Windows.

Determining an Effective Analog Sampling Rate

Q: How often should my equipment make measurements? A: This question often arises when people draft plans to automatically measure a physical quantity such as temperature, pressure, acidity, liquid level, and so on. You can approach this problem in several ways, from an educated guess to a mathematical analysis of your system. The examples that follow use temperature measurements because people measure temperature more than any other physical characteristic.

High-Performance Computing Drives A Growing, Evolving Internet of Things

Not too long ago, the idea of bringing intelligence to physical objects in our world and interconnecting them might have seemed like science fiction. Yet it is happening right now, as the phenomenon we call the Internet of Things (IoT) takes shape.

The Self-Driving Car

Since the first demonstration of a radio-controlled car in 1925, the automotive industry has been seeking to build a reliable driverless vehicle. The safety of robot-quick reflexes and predictive algorithms, combined with the convenience of effortless travel, is appealing. For those who cannot physically drive, an autonomous car allows a new level of freedom. Of the 5.5 million car crashes per year in the United States, 93 per- cent of them have a human cause as the primary factor.1 A self-driving car could reduce such accidents and, as a bonus, use its predictive driving to reduce fuel consumption and traffic congestion.

Reliability Testing of GORE® Protective Vents in LED Luminaires

Outdoor lighting systems are designed with sealed housings to protect against environmental contaminants. Atmospheric conditions such as temperature shifts and relative humidity present challenges to the reliability of outdoor luminaires. Changes in ambient temperatures can lead to significant pressure differentials. Over time, pressure on the enclosure seals can cause them to fail and allow contamination and/or water to breach the enclosure. This shortens the life of the luminaire by damaging the wiring, leads and other electronics of the power supply driver and the LEDs. The moisture also reduces light efficiency and can cause condensation to form on the lenses and reflectors.
