Saliva is an easily accessible body fluid that contains important biological markers that can be used to monitor the health of an individual. A saliva collection device called the Saliva Procurement and Integrated Testing (SPIT) booklet was developed for use in remote locations, and doesn’t require any special storage conditions. The booklets contain filter paper pages that are used to collect saliva samples over a specified time. The samples are dried at room temperature, and are stable for up to six months.

The State of Earth

U.S. Senator Gaylord Nelson created Earth Day in 1970. Over the years, Earth Day grew in popularity and in 2009, the United Nations officially named April 22 as International Mother Earth Day. Earth Day (www.earthday.org) is now celebrated by over one billion people in nearly 200 countries.

Advanced Capabilities of PXI-Based Semiconductor Test Systems

The ongoing challenge for today’s semiconductor test engineers is to identify and create new test solutions that can offer significantly lower test costs as well as address the need for configurable, open-architecture, flexible test solutions that can provide comparable features to proprietary ATE platforms. In particular, for test requirements with low to moderate volumes — such as pilot production, verification, and focused production test applications — the need for flexible and cost-effective ATE solutions is particularly acute. For these applications, test engineers historically have relied upon legacy test systems that have a low acquisition cost, but high operating costs or in-house designed rack-and-stack solutions. However, semiconductor test system solutions based on the PXI platform have made significant advancements in functionality and performance over the past three or four years, offering test engineers a viable alternative for both current and future test needs.

Calibration Requirements for Testing Coupling-Decoupling Networks

Coupling-Decoupling Networks (CDNs) are the unglamorous workhorses that get “hitched up” to an impulse generator in order to perform impulse testing on powered equipment. As such, performance and calibration requirements for CDNs have not been specified to the same level of detail as the impulse generator. This is no longer the case with the Third Edition of IEC 61000-4-5, the international standard for surge immunity testing.
