Recent semiconductor design technology has been substantially developed that we can design a micro-system on a chip as well as implementing an application specific IC in an FPGA. SPARTAN-3E developed by Xilinx is equipped with an FPGA that holds as much as 500 thousand transistors connected with MicroBlaze softcore microprocessor bus system. In this paper, we discuss a method of implementing an embedded system using the SPARTAN-3E. We also explain the peripherals and the bus protocols and the expandability of this kind of embedded systems.

fac-RuH(NO)(ttp) is fluxional in the range between 180 K and 303 K. The structures involved in this fluxional process are found to be a mixture of two square pyramids and a trigonal bipyramid from the low temperature NMR spectra and the line shape analysis using DNMR 3 program and the activation parameters of this process were determined by using the simulated data. The mechanism of this fluxional process is proposed to be a pathway known as Turnstile Rotation.

In this paper, we designed and implemented a visible light identification(VLID) system consisting of a VLID reader and a tag which backscatters incident lights from the reader. A VLID tag sends its ID to the reader by switching an LCD shutter which is located on its surface. The VLID reader consists of six LEDs and a photodiode(PD). The LEDs emit visible light and a PD located in a center position of LEDs receives backscattered light from the VLID tag. A microcontroller and a commercial liquid crystal display(LCD) shutter for 3D-TV glasses are used to implement a VLID tag. Experiments were conducted to confirm VLID system performance. We successfully demonstrated experiments to send NRZ-OOK signal of 100 bps over a distance of 35 cm at daytime. Also, we suggested the theoretical maximum transmission rate and the various methods to enhance the separation distance between a VLID reader and a tag.
