Cyber-Physical Magnetic Field Sensors

Kravljaca V., Rochester Institute of Technology, US

Solid state magnetic field sensors are examined. The use of III-V semiconductors in Hall effect sensors results in high bandwidth, fast response time, adequate spatiotemporal resolution, accuracy and sufficient measurement range. Despite significant advantages, there [...]

Current-mode Processing Possibilities in HV SoI Integrated Systems

Jankowski M., Napieralski A., Lodz University of Technology, PL

The paper discusses possibilities of current-mode based functional block implementation into signal path of HV SoI voltage-mode circuits. The topic arose as an effect of research on HV SoI ASICs for automotive applications. It turned [...]

Fetal Movement Detection Based on MEMS Accelerometer

Minjie L., Yongkang T., Yunfeng L., Song Y., Jingxin D., Tsinghua University, CN

Fetal movement is a significant indication of fetal well-being. Standard clinical fetal monitoring technologies include ultrasound imaging and cardiotocography. Both have limited prognostic value and require many health resources. We have recently developed a low-cost, [...]

Audio Signal Processing Using Mixed Hardware-Software Approach

Rominski A., Ciota Z., Napieralski A., Technical University of Lodz, PL

In this paper the possibilities of modern audio-processing systems have been described. One of the most important tasks is a proper definition of feature vectors. For example, the long-term spectra vector has been chosen as [...]
