Sampled Systems LLC was formed in 2004 by founder and principal Duane Mattern. From 1998 to 2004, Duane worked as an independent engineering consultant and subcontractor. During this time he gained experience in a wide variety of technologies and products. The common thread throughout these projects was new product development with an interdisciplinary mix of software development, real-time sensing, and embedded processing.
