Machining Characteristics

This study aims to verify whether the three-dimensional internal information acquisition system we have developed can be applied successfully to the microstructures of consecutively precision-machined biological samples, and to those of metallic samples. Therefore, this study mainly deals with biological hard tissue samples like bones. In this paper, we first studied the precision-machining characteristics of bones. From this, we determined that, to obtain machined surfaces sufficient for internal observations, we need to determine the maximum uncut chip thickness and the cutting speeds, taking the bone’s anisotropy into consideration. Next, we acquired three-dimensional internal information on consecutively precision-machined bone samples using the three-dimensional internal acquisition system we developed. Subsequently, we visualized the internal structures of these machined samples. Our tiling observations acquired an 18×9×3 mm segment as a 6.2×6.2×10μm resolution image. We obtained a three-dimensionally reconstructed image of complex blood vessel networks inside the bone by making the acquired images binary.

In this paper, based on characteristic analysis of driver training operation, a new approach of information acquisition for driver training is found, which is through extracting acceleration information. The information acquisition device which is under MEMS three-axis acceleration transducer, based on ADXL335 and MCU, can achieve real-time and accurate measurement of vehicles’ three-dimensional acceleration. By comparing the change curve of measured acceleration with the related data of good driver, the existing problems will be found out. In this way, the driver training operation can be assessed in a timely way.

As requirements for the acquisition of workshop production information tends to be more instant and reliable, this paper proposed a workshop production information acquisition system based on RFID and ZigBee technology. After analyzing the system information demand, this paper designs the system physical structures, communication protocol, tag encoding and software hierarchy. Finally, designs and implements the server-side and terminal-side system which can make information acquisition more real-time and make the production more efficient.

The Real

In the radar target validation systems, the flight information as an important external information source occupies the irreplaceable position. However, in the resent researches, how to obtain the flight information stays focused and unsolved. The Real-time Multi-task Flight Information Acquisition System we designed and realized in this paper could obtain the flight information in real time and provide the real-time, reliable, detailed and complete flight information for the detective area. This system has already successfully used in Airway-nonairway Classification in an ATCRS (Air Traffic Control Radar System).
