2. 1. Micromachined Three-Axis Accelerometers and Sensor Readout Electronics

   Author : Henrik Rödjegård; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three axis accelerometer; sensor readout; inertial sensors; gyroscope; MEMS; digital feedback; capacitive readout;

   Abstract : Miniaturized, MEMS-based, inertial navigation systems are used to track the position of moving objects without an external reference system. Several existing and future applications such as indoor navigation, stability control of vehicles, active prostheses or training aids for sportsmen would benefit from the small size and the low cost of micromachined inertial sensors.

4. 2. Geometric Models for Rolling-shutter and Push-broom Sensors

   Author : Erik Ringaby; Per-Erik Forssén; Tomáŝ Pajdla; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Almost all cell-phones and camcorders sold today are equipped with a  CMOS (Complementary Metal Oxide Semiconductor) image sensor and there is also a general trend to incorporate CMOS sensors in other types of cameras. The CMOS sensor has many advantages over the more conventional CCD (Charge-Coupled Device) sensor such as lower power consumption, cheaper manufacturing and the potential for onchip processing.

5. 3. Inertial motion capture for ambulatory analysis of human movement and balance

   Author : Fredrik Olsson; Kjartan Halvorsen; Peter H. Veltink; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inertial sensors; Human motion capture; Calibration; Neuromuscular control; Human balance; Tremor quantification;

   Abstract : Inertial sensors (accelerometers and gyroscopes) are ubiquitous in today’s society, where they can be found in many of our everyday mobile devices. These sensors are capable of recording the movement of the device, and by extension, the movement of humans carrying or interacting with the device. READ MORE

7. 5. Inertial Sensor Arrays : Sensor Fusion and Calibration

   Author : Håkan Carlsson; Joakim Jaldén; Thomas Seel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Motion estimation using inertial sensors is today used in a wide range of applications, from aircraft navigation to inflatable bicycle helmets. The accuracy with which the motion can be estimated using inertial sensors depends on how large the measurement errors are. READ MORE
