Vibratory beam angular rate sensors are fast becoming the most widely used sensors in many applications. The mathematical modeling on the quadrature error of quartz beam vibratory angular rate sensor was presented in this paper. The effects of quadrature error model to the sensor's performance were analyzed based on the analysis of work principle and error induced by quadrature. And the correlation...
This paper reports a MEMS gyroscope that is driven by the rotating carrier's angular velocity. The structure and fabrication are introduced in the paper. The silicon processing and simulating of the sensing unit are studied. We use coventor ware to simulate structure. And in process, we use spray coating instead of spinning coating. In simulation, the first modal frequency we obtained is 220.38Hz,...
Through laser ablation process, a diaphragm with mesa structure is fabricated successfully in silicon wafer with Nd:YAG laser machining system. Then the silicon diaphragm is used to make optical fiber Fabry-Perot pressure sensor. The pressure sensing experiment showed the sensor had a good linear response with sensitivity 10.6 nm/kPa at the range 40–240 kPa.
Sensor networks open up new opportunities to observe and interact with the physical world around us. Although there have been many advances in sensor network applications and technology, sensor networks still suffer from the major problems of limited energy due to the difficulties of replacing batteries when they ran out. We aim to improve the efficient processing of continuous queries, by which query...
Complete coverage path planning is a key problem for autonomous cleaning robots, which concerns not only the cleaning efficiency but also the adaptability to unstructured environments. But the diversity of environments and limited perception ability of the robot make the problem still unsolved. In this paper, a novel strategy of combined coverage path planning is proposed, which combines the random...
This paper reported the structure rule and the signal processing technique of the sensor that utilizes the gas pendulum property of natural convection in the hermetic chamber to sense carrier obliquity. The sensor organ design, signal processing technique and software compensation effect of one dimension, two dimensions and omnidirectional tilt sensors were presented
We report a novel frequency-shifted interferometer for interrogating multiplexed fiber grating sensors. This cw technique is capable of distinguishing gratings even when their reflection spectra overlap, suitable for very large sensor arrays.
