Orientation is one of the most important problems of visually impaired people. The aim of this paper is to suggest a contribution to the solution of this problem using computer technology. The basic idea is the detection of motion and orientation using sensors and consequent position identification. The detected trajectory is compared with a map and is corrected by means of the algorithm descri...

Drowsy driving is one of important factors to cause the car accident. The parents usually worry about the traffic safe of their children. Therefore, we proposed a drowsy detection and monitoring system through Internet in this paper. Firstly, the brain wave was captured by single channel EEG device. Therefore the drowsy state of driver can be analyzed by drowsiness detection system. The system ...

We propose a high-sensitivity and wide-dynamic-range position sensor for range finders using logarithmic-response and correlation circuit. The 3-D measurement system using the proposed position sensor has advantages to applications, such as a walking robot and a recognition system on vehicles, which require both of availability in various backgrounds and safe light projection for human eyes. Th...

Without reconstructing the signal themselves, signal detection could be solved by detection algorithm, which directly processes sampling value obtained from compressive sensing signal. In current detection algorithm, as the judgment criterion, the threshold depends on Monte Carlo simulations, which takes too much time, affecting detection efficiency. Therefore, in this paper, we propose an algo...

High-precision position detection of joint and status monitoring speed reduction gearbox (SRG) are two key technologies in the research development selective compliant assembly robot arm (SCARA). The existing schemes have some problems, such as large occupation space, high cost, complex implementation, lack monitoring, etc. Therefore, first, order to get accurate information when SCARA is power...
