Starting with variable gap capacitive sensor, and based on the reliability analysis of manufacture, a rectangular membrane sensor array is presented with a P+ beam on its backside as the supported and etch stop layer. With this bearing structure, the reliability and applicability of the pressure sensitive cell is therefore improved. The finite element method (FEM) is adopted to calculate the mechanical characteristic of the configuration that mentioned above and to analysis influence of the beam's dimension on the performance of the sensor. The practical fabrication process is conceived in the end.

Digital grating sensor of vibration measurement is a pattern of geophone, which picks up seismic signals with grating vibrator. Along with the request of higher precision method to identify more complex geological targets, higher precision and accurate information of oil reservoirs underground must be provided through geophysical technologies for reservoirs prospecting and developing. By digital grating sensor of vibration measurement, mechanical vibrating signal of the seismic wave can be transformed into light modulating signal - moire fringes, and then converts by photoelectric element to digital electrical signal. The sensor samples the signal by counting the numbers of the moire fringes, which may prevent quality of the output data from being influenced by electric circuits, and the packaging technology is also simplified. The working principle, theoretical arithmetic, configuration design, test method and acquired data by digital grating sensor are presented in the paper.

The SnO/sub 2/-Ag thin film was prepared by magnetron sputtering on the Si-based membrane substrate embedded with a platinum micro heater. The sensitive properties of the film to H/sub 2/S were investigated, and the R-T relation was measured in temperature pulsed operation mode and in simple temperature ramp mode in order to understand the sensitive properties. The results are used to discuss the effect of Ag additive on the R-T relation and sensitive properties of the film. The variation of film resistance shows that the silver promotes the chemical processes on the surface of films. The R-T relation measured in temperature pulsed operation mode can be used to understand the sensing properties of SnO/sub 2/-Ag film.

With respect to the limitation of the image recognition method by single BP neural network, a new method based on multiple BP neural networks with D-S theory is proposed. By using this method to synthesize each image recognition result of single BP neural network, we can improve the performance of the image recognition. The results of the computer simulation and experiment show that the new method is effective.

A method for articulated-pose identification from the silhouette of a human body is presented in this paper. First the method employs an energy function to extract a dummy skeleton of a human body from the silhouette, and then estimates the position of the joints by the knowledge of anthropotomy and three rules given by the standard human skeleton model. The three rules can help us to judge whether a point on the skeleton is a joint or not. The experimental results show that, the method is effective. It requires no any additional restrictions on the motion and color of a human body. Meantime the method is robust against the noise in the silhouette. Especially it has good performance in the case of complicated background.

Based on Lyapunov stability theory, a novel adaptive controller is designed for a unified chaotic system. Parameters identification and synchronization of the chaotic system can be carried out simultaneously. Simulation results with different parameters show the effectiveness of the proposed controller.

Information chain consists of information acquisition, information processing, information transmission and information application. Compared with the other three technologies, information acquisition has dropped far behind and is becoming a bottleneck for the rapid development of the time. Embedded system has been successfully applied in industrial automation, communication system, wireless communication, Internet, consumer electronic and other fields that contact toughly with information processing, information transmission and information application. It is the outcome of development of the information chain's back-end link, if applied into information acquisition, there should be sound effects. The paper does some try to apply embedded system into information acquisition. This can contribute to the development of information acquisition.

It is discovered that the natural convection gas has the pendulum characteristic, which leads to the introduction of the new concept of gas pendulum. In this paper, the buoyancy lift of natural convection gas is analyzed in a hermetic chamber, and the relationship between the buoyancy lift and the change of temperature is formulated. The experimental results have shown that the gas pendulum can be utilized to sense the acceleration and the tilt angle similar to the solid pendulum and liquid pendulum.
