1. 1. Fast Clock Synchronization for Large-Scale MEMS Ultrasonic Transducer Arrays

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Karl-Johan Karlsson; [2022]
   Keywords : clock synchronization; clock deskew; MEMS transducer; Delay line; Time-to-Digital conveter;

   Abstract : In many systems today sensors or transmitters need to be read or controlled simultaneously. This thesis investigates a new architecture used for deskewing clock signals between multiple separated parts of a signal transmission system. READ MORE

3. 2. Remote control of mechanical rat traps based on vibration and audio sensors

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Denis Solak; Amin Storani; [2019]
   Keywords : Technology and Engineering;

   Abstract : The main aim with this master’s thesis was to study the possibilities of detecting an event (rat trap going off) by analyzing audio streams from a MEMS (micro-electromechanical systems) microphone or movement patterns from a MEMS accelerometer. To achieve this goal, a small, power efficient and cost efficient embedded system was built with the help of a development board, a MEMS accelerometer, a MEMS microphone and a metal box where the equipment and the rat traps were placed and positioned.

4. 3. Tampering Classification Using Accelerometer Data

   University essay from Lunds universitet/Matematik LTH

   Author : Mikael Lindholm; Linus Lindgren; [2017]
   Keywords : machine learning; classification; accelerometer; support vector machine; doorstation; tampering detection; Mathematics and Statistics;

   Abstract : Network Video Door Stations are IP-based door stations for two-way communication, identification, and remote entry control. They have a number of different sensors e.g video, audio and accelerometer that can measure external data. READ MORE

5. 4. A microtechnology-based sensor system for deepwater analysis from a miniaturized submersible

   University essay from Ångström Space Technology Centre (ÅSTC)

   Author : Katarina Smedfors; [2010]
   Keywords : CTD; MEMS; microtechnology; sensors; thin film metallization; microelectrodes;

   Abstract : The aim of this master thesis has been to design, and partly manufacture and evaluate, a highly miniaturized, on-chip conductivity-temperature-depth (CTD) sensor system for deepwater analysis also including electrodes for pH and chloride ion concentration measurements. The microtechnology-based sensor system will be a vital instrument onboard the Deeper Access, Deeper Understanding submersible, which will be small enough for deployment through bore holes into the subglacial lakes of Antarctica.
