Key objectives for connected product trials

Connected products are sufficiently complex that a field trial is an essential stage between workshop development and mass production. This paper discusses the key objectives of a trial and, most-importantly, how to tell when you’ve finished your trial and are ready for launch. A trial is, by definition, an experiment. You hope everything will go smoothly but you should also anticipate surprises and expect to learn something. If you were confident that there’d be no surprises you wouldn’t be doing a trial. But neither is it an open-ended learning process, it should have definite goals, both of risk-reduction (catching mistaken assumptions that are costly to put right later) and of confidence

Design paradigms for solving sensor detection reliability problems

There are two main paradigms for solving classification and detection problems in sensor data; model-driven and data-driven. This article explores how digital signal processing using low power micro-computer units (MCUs) connected to an analog sensor was used to produce significantly improved quality of signal data. The problem to solve was one of false no detection. Model-driven is the way everybody learnt to do it in Engineering School. Being a graduate of Imperial College, London - this is how I learned. Start with a solid idea of how the physical system works. Consider the states or events you want to detect, generate a hypothesis about what aspects of that might be detectable from the o
