	808nm high-power semiconductor laser therapeutic apparatus based on LPC2138 (EI CONFERENCE) 会议论文 OAI收割 2011 IEEE International conference on Intelligent Computation and Bio-Medical Instrumentation, ICBMI 2011, December 14, 2011 - December 17, 2011, Wuhan, Hubei, China 作者: Wang B.; Wang B. 收藏 \| 浏览/下载：39/0 \| 提交时间：2013/03/25 In this paper we designed an intelligent 808nm high-power semiconductor laser therapeutic apparatus with the LPC2138 ARM processor. The laser is driven by the digital constant current source module and the apparatus has good human-machine interaction performance on account of set the parameters intelligently. The function such as operation mode output power output pulse width and pulse cycle could be easily set through the TFT touch screen. The application software could transmission the log data to the computer by the USB interface in order to check and study the records later. 2011 IEEE.
	Technology of USB HOST applying in traffic controller based on ISP1161A (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Electronic and Mechanical Engineering and Information Technology, EMEIT 2011, August 12, 2011 - August 14, 2011, Harbin, China Haibo L.; Song K. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 Control and management of the urban traffic signal is an problem that modern city has to face. The traffic signal controller makes a great contribution to the improvement of traffic status and the reduction of traffic jam. A traffic controller is designed using the technology of USB host based on ISP1161A. Universal serial bus is new interface bus architecture for PC which supports the PnP function Of PC peripheral equipments and has been widely used in computer and communicational devices. ISP1161A complies with the protocol of USB1.1 and is used as the core part of the system. As a new try the USB host technology is applied into the design of controller to implement the communication with PC. Configuration of scheme is carried out successfully. The USB host technology makes configuration of scheme and future update easier and more convenient. 2011 IEEE.
	The development and design of the gas-liquid two-phase flow-meter system based on DSP (EI CONFERENCE) 会议论文 OAI收割 2008 International Conference on Advanced Computer Theory and Engineering, ICACTE 2008, December 20, 2008 - December 22, 2008, Phuket, Thailand Zhu J.-W. 收藏 \| 浏览/下载：47/0 \| 提交时间：2013/03/25 Recently as the fast development of the modern engineer the measuring problem of the gas and liquid is becoming prominence and many countries spend so much in the research. The system with which the thesis developed has realized data acquisition data compression and decompression a friendly human-machine interface RS232 serial communication reading or writing USB disk. The architecture of system is flexible. The thesis presents a research on the measurement process and the whole structure of the flow metering system and analyzes the schematic circuit of the main hardware modules 2008 IEEE.
	An image identification system of seal with fingerprint based on CMOS image sensor (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China 作者: Xue X.-C. 收藏 \| 浏览/下载：21/0 \| 提交时间：2013/03/25 CMOS image sensors now become increasingly competitive with respect to their CCD counterparts while adding advantages such as no blooming simpler driving requirements and the potential of on-chip integration of sensor analog signal conditioning circuits A/D converter and digital processing functions. Furthermore CMOS sensors are the best choices for low-cost imaging systems. An image identification system based on CMOS image sensor is used to identify the seal images that include fingerprint and then determine whether the seal is fake or not. The system consists of a color CMOS image sensor (OV2610) a buffer memory a CPLD a MCU (P89C61X2) a USB2.0 interface chip (ISP1581) and a personal computer. The CPLD implement the logic and timing of the system. The MCU and the USB2.0 interface chip deal with the communications between the images acquisition system and PC. Thus PC can send some parameters and commands to the images acquisition system and also read image data from it. The identification of the images of seal is processed by the PC. The structure and scheme of the system are discussed in detail in this paper. Several test images of seal taken by the system are also provided in the paper.
