A novel information system for detecting mastitis in dairy cattle and managing their milking processes in the milking parlor is designed. The system comprises three major subsystems—the mastitis detection device, the information display device, and the cloud database. The mastitis detection device can detect and evaluate the degree of mastitis immediately before the milking operations are carried out. The information display device shows information on the health of the dairy cattle obtained from a cloud database to manage the milk production of a dairy farm. Importantly, the proposed system utilizes a wireless sensor network (WSN) with low power consumption that connects the information display device with the remote management system. Experimental results reveal that our proposed system can reduce the risk of milking cattle with mastitis and improve efficiency of milk production.

Full-Color LED display-Screen is widely used as a new information display device in all aspects of life, the large Full-Color LED Display-Screen color is composed of enhanced MCU or ARM, but the real-time and flexibility of the control system do not satisfy the require of people ,With the continuous improvement of people's living standard. FPGA is favored by the embedded development generally,so a new Full-Color LED Display-Screen was designed based on FPGA and ARM, the system choose the Cortex-M3 ARM as kernel board controller, using the FPGA to scan and control display data, using WI-FI wireless network to communicate though the computer software. The test shows that the system is reasonable, realizable, operated easily, flexible, adaptable environment, low price. This system can support picture to display on 256 gray-scale full-color, and can be communicate with WI-FI on high speed and it will be used widely in the practical system.

Full-color LED display-Screen is widely used as a new information display device in all aspects of life, but its flat and static display could not cater to peoples dynamic visual change ,and its lack of intelligence capability makes it a defect not to respond timely with special outside change. ARM and FPGA With high speed and programmable features having been used widely in applications of the embedded development and we provide the method to design of Intelligent Full-Color LED display-screen system based on ARM and FPGA. The control system employs Cortex-M3 core-based ARM as its mail controller, the temperature and humidity sensor, microwave sensor, an infrared sensor are adopted for outside information, and FPGA scan control unit for the color data display. Brushless Direct Current Motor (BLDCM) possessing Superior performance in control unit is widely well applied. The experiments show that the reasonable modular design of the program enables its smooth rotation within the range of 45°-135°, and it timely response to various changes on the outside. Thus LED can display 256 data intelligently which ensures the market prospects. Key words: IntelliSense ; ARM ;FPGA; Full-color LED display-Screen ; Cortex-M3;BLDC motor

For centuries, the right place to look, when in search of the best archaeological knowledge, has been in some kind of printed book. There will once have been a manuscript, and if the book never materialized, a manuscript may substitute, but what usually matters is the better truth that has the authority of print.In a now-standard joke, a wizard of a yet-newer information display system is described: hugely flexible in size and in format and in what it can present, made of cheap and common materials, wholly recyclable, and — best of all — requiring no screen or display device of any kind whatsoever. At some point you realize the miracle being described is a book. But the book is for many purposes deservedly obsolescent, and archaeological research is in truth already in the age beyond the printed book. Specialist illustrated publications have high fixed costs in the print, and low circulations mean there are too few copies to spread the costs over. When the first new technology of cheap reprographics came in a generation ago, the ‘grey literature’ of field reports began to grow, soon reaching a point at which no library and no individual could be relied on to possess the ‘collected literature’ on any topic of large range. Now an increasing amount of archaeological knowledge is only or better made accessible electronically.

In this paper we discuss a model to estimate the power consumption and lifetime (LT) of an OLED display based on its pixel value and the brightness setting of the screen (scbr). This model is used to illustrate the effect of OLED aging on display color characteristics. Model parameters are based on power consumption measurement of a given display for a number of pixel and scbr combinations. OLED LT is often given for the most stressful display operating situation, i.e. white image at maximum scbr, but having the ability to predict the LT for other configurations can be meaningful to estimate the impact and quality of new image processing algorithms. After explaining our model we present a use case to illustrate how we use it to evaluate the impact of an image processing algorithm for brightness adaptation.
