National Instruments® (NI) pioneered virtual instrumentation more than 25 years ago with the introduction of LabVIEW-fully graphical development system. On several platforms they offer software products that deliver the proven productivity gains of virtual instrumentation. Over twenty years at the Department of Measurement and control VSB-Technical University of Ostrava the students have taken advantage of the flexibility and open development model to solve applications in a wide variety of cases. Computer laboratories equipped by flexible hardware components make education and research cheaper and more productive and improve the way students learn. Rather than focusing on sometimes tedious methods of software development for gathering data, educators and students can focus on results and concepts. Students still learn methodology, but spend the majority of their time executing their experiments instead of building them. © 2011 IEEE.

A smart grid-base AMI (advanced Metering Infrastructure), which checks electricity consumption and controls the electric energy used with the demand response technique, is necessary for remotely managing the load of the energy and power consumed in order to comprise energy efficiency for electrical devices in homes. The smart controller calculates the amount of electricity consumed by customer on real time basis from the utility supplier like electric supply company. In this paper, we propose the hardware architecture and software of the smart controller for use as the platform in smart grid system to reduce energy consumption. The smart controller can be installed on the electric plug of the electric appliance. The smart controller grasps the energy amount used in the electric appliance and delivers to the AMI / EMS (Energy Management Server). In addition, we evaluated an experimental system to practically verify functions of the smart controller which is attached to the lighting device. From the system, we showed that the electric source of the illumination can be controlled according to the load change and saved energy effectively. We also confirmed the structural benefit and the energy-efficient effect through the verification of the smart controller.

2nd International conference on Adaptive Optics for Extremely Large telescopes, AO for ELT 2011

作者： Dipper, N.A. Basden, A. Geng, D. Younger, E.J. Myers, R.M. Centre for Advanced Instrumentation Department of Physics Durham University South Road Durham DH1 3LE United Kingdom

Adaptive Optics systems for instruments on the next generation of astronomical telescopes will be of a significantly higher order than those for existing systems. The requirements for processing power for real-time computers to control such systems will be substantial and may well not be met by the simple application of the next generation of CPU based computers. We present here an overview of the various designs for future real-time computer systems that are being investigated at Durham involving the acceleration (or replacement) of CPU systems by GPU and FPGA based hardware. We address the ongoing argument of which of these technologies should be employed for which applications. We present our plans for the testing of these technologies both in the laboratory and on-sky in the CANARY AO demonstrator at the 4m William Herschel telescope, along with initial results and a design for the realtime control system for the proposed EAGLE instrument for the E-ELT.

We consider the problem of implementing security algorithms into embedded systems deployed in automation applications. Such systems are typically built on embedded microcontrollers with limited resources and as hardware changes may not be possible or convenient, the software based cryptography is a suitable solution. In this paper we present results of performance benchmarks of different software-implemented symmetric cryptography algorithms on 8 and 16-bit microcontroller platforms. The contribution of the work is in comparing performance of different algorithms, embedded microcontroller platforms, effects of optimizations and different implementations. © 2011 IEEE.

GM/CA-CAT at Sector 23 of the advanced Photon Source CAPS) is an NIH funded facility for crystallographic structure determination of biological macromolecules by X-ray diffraction. A second-generation Berkeley automounter is being integrated into the beamline control system at the 23BM experimental station. This new device replaces the previous all-pneumatic gripper motions with a combination of pneumatics and XYZ motorized linear stages. The latter adds a higher degree of flexibility to the robot including auto-alignment capability, accommodation of a larger capacity sample Dewar of arbitrary shape, and support for advanced operations such as crystal washing, while preserving the overall simplicity and efficiency of the Berkeley automounter design.

This work proposes an image-guided robotic Mastoidectomy. A surgical navigation software was developed to guide the robot without damaging the critical area. A forbidden-region virtual fixture is implemented for safety. A human-robot collaboration control mode is used to allow the human intervention during surgery, to compensate tremor by operator, and to protect the relevant organs. A temporal bone replica was used as a phantom for the robotic Mastoidectomy. Through the phantom studies, it was shown that the image-guided robotic approach is effective for safe and precise Mastoidectomy. © 2011 IEEE.

Astronomical telescope is a powerful tool for star observation, but adjusting a telescope is timeconsuming. For most of astronomy amateurs, their telescopes don't have an intelligent system to ease the adjustment of telescope. Therefore, we propose an integrated system for astronomical telescope. The integrated system presents a friendly telescope control interface and provides functions including telescope monitoring, star targeting, star profile retrieval and star tracking. The most powerful feature of the integrated system is star tracking. By using camshift algorithm and PID controller, the star tracking module can help user track certain objects such as plant and comet.

With the background of practical automatic control project of stage mechanical equipment in Qujing, Yunnan, P.R. China, high levels configuration software of Schneider Electric named Monitor Pro7 is introduced to accomplish the task of monitoring and controlling on site. Related structure diagram of the control system is shown and the function of Monitor Pro7 is emphasized. The characteristic of the project is that almost all control buttons imbedded in 238 pictures which configured under Monitor Pro7 would be used to satisfy the demands of operator, and other functions as complicate logic organization and judgment, real-time alarm and security protect are also well supported at the same time. The faults of Monitor Pro7 needed to be improved are also discussed at the end.

This article describes the problem of the automatic production of a tuning fork with a tip for atomic force microscopy (AFM). It contains hardware and software (image processing) description of a self acting machine developed to solve the problem. The image processing main goal is to measure distances between individual parts during the fabrication process. A camera with high resolution and macro objective is used to acquire images during the assembly process. For getting better results, we perform correction of the used camera distortion and its calibration. Together with proposed image processing methods we use the camera as an accurate distance sensor. So obtained data we then used to control the process. We implemented proposed image processing methods in C++ using Intel OpenCV library. The machine is able to produce the tuning fork with the tip with constant parameters, which is important for future work with the microscope. © 2011 IEEE.
