		<description><![CDATA[With the midterm elections in the United States winding down, I thought I’d try to tie embedded design concepts to the process of elections. On some of the aerospace projects I worked on, we used voting schemes as fault tolerant techniques. In some cases, because we could not trust the sensors, we used multiple sensors, [...]]]></description>

		<description><![CDATA[AT&#38;T’s recent national outage of their U-Verse voice service affected me for most of one day last month. Until recently, such outages never affected me because I was still using a traditional landline phone service. That all changed a few months ago when I decided that the risk and consequences of an outage might be [...]]]></description>

		<description><![CDATA[A key tenet of fault tolerant designs is to eliminate all single points of failure from the system. A single point of failure is a component or subsystem within a system such that if it suffers a failure, it can cause the rest of the system to fail. When I was first exposed to the [...]]]></description>

		<description><![CDATA[The recent articles claiming BP was demonstrating carelessness and complacency when the company cut corners in their well design got me thinking. Companies and design teams constantly improve their process in ways that cut costs and shrink schedules. This incremental process of “cutting corners” is the cornerstone of the amazing advances made in technology and [...]]]></description>

		<description><![CDATA[I had a conversation recently with Nat Hillary, a field application engineer at LDRA Technologies, about examples of software fault tolerance, quality, and security. Our conversation identified many questions and paths that I would like to research further. One such path relates to how software systems that are not fault tolerant may present vulnerabilities that [...]]]></description>

		<description><![CDATA[I commented earlier this week about how watching the BP oil well capping exercise live video reminded me about building and using formal test procedures when performing complex or dangerous operations. Before I had a lot of experience with test procedures, I used to think of them as an annoying check-off box for quality assurance. [...]]]></description>

		<description><![CDATA[Watching the BP oil pipe-capping live-video the other day made me think about formal procedures. Using a formal procedure is a way to implement the fault tolerant principle in cases where the operator is an integral part of the system’s decision process. Using a formal procedure helps to free up the operator’s attention while performing [...]]]></description>

		<description><![CDATA[[Editor's Note: This was originally posted on the Embedded Master] For many applications, the primary focus of robust design principles is on making the design resilient to rare or unexpected real world phenomenon. Embedded designers often employ filters to help mitigate the uncertainty that different types of signal noise can cause. They might use redundant [...]]]></description>

		<description><![CDATA[[Editor's Note: This was originally posted on the Embedded Master]  Fault tolerant design focuses on keeping the system running or safe in spite of failures usually through the use of independent and redundant resources in the system. Implementing redundant resources does not mean that designers must duplicate all of the system components to gain the [...]]]></description>
