Towards Understanding Architectural Tradeoffs in MEMS Closed-Loop Feedback Control
"... Micro-Electro-Mechanical Systems (MEMS) combine lithographically formed mechanical structures with electrical elements to create physical systems that operate on the scale of microns. However, the physical scale of MEMS devices can make controlling them computationally challenging because the time c ..."

by this new and growing domain. Working with domain experts in the area we characterize the classic tight feedback control loops required by these next generation MEMS devices, we explore the sources of overhead when using existing programmable systems, and we compare these approaches to an application

Review Progress of MEMS Scanning Micromirrors for Optical Bio-Imaging
, 2015
"... Abstract: Microelectromechanical systems (MEMS) have an unmatched ability to incorporate numerous functionalities into ultra-compact devices, and due to their versatility and miniaturization, MEMS have become an important cornerstone in biomedical and endoscopic imaging research. To incorporate MEMS ..."

MEMS into such applications, it is critical to understand underlying architectures involving choices in actuation mechanism, including the more common electrothermal, electrostatic, electromagnetic, and piezoelectric approaches, reviewed in this paper. Each has benefits and tradeoffs and is better
Magnet: Robust and Efficient Collection through Control and Data Plane Integration
"... Despite being a core networking primitive, collection protocols today often suffer from poor reliability (e.g., 70%) in practice, and heavily used protocols have never been evaluated in terms of communication efficiency. Using detailed experimental studies, we describe three challenges that cause ex ..."

. Magnet’s link estimator addresses the inaccuracies in link estimation by using feedback from both the data and control planes, using information from multiple layers through narrow, platform-independent interfaces. Second, Magnet addresses link dynamics by using the Trickle algorithm for control traffic

dynamical processes, among others. Thus, it is important to blend ideas from information theory and control theory to address problems at the core of such distributed systems. This dissertation looks at communication scenarios, in which there are feedback channels available for enhancing communication
