For large volume of existing projection device, active power, portable difficult issues such as the design of the wireless projection system based on WLAN and 3G. This paper achieved wireless transmission of projected information, supporting 3G wireless network connection, the formation of a wireless...

As most existing device sharing technologies are only abstract operations sharable, such as read and write, virtual desktop users can't share the device-specific characteristics of USB devices attached to cloud terminal. In this paper, we propose USB device redirection as a peripheral bus extension over...

The new designed acousto-optic device has adjustable, it is 1.5 times to extend its length. Fitting plastic optic fiber into transparent tube, the path of light can be increased and the light area will be enlarged. The device can present different color mode of light with RGB and high light LEDs as the...

A feasible and novel design and implementation scheme of embedded video surveillance system, which is based on improved H.264 and Wi-Fi, is proposed in this paper. A video server, built on an ARM11 platform with a wide range of peripheral interface, is responsible for capturing image data using Video...

With computer of development, especially hardware technology of development, traditional of RS232 serial interface has displayed out increasingly more of insufficient, but large of instrument instrument, and industrial control system, and remote data terminal, equipment still using RS232 serial interface...

In this paper a method of the design of Data Sampling Terminal is introduced. The system consists of four main parts: temperature collecting, ECG collecting, the main control circuit, and Bluetooth communication module. Another, it also consists of data processing software. Body temperature acquisition...

Mobile infrastructure technological development in the last decade leads to novel mobile commerce based advertisement addressing the businesses and end-consumers. Although location-based services developed rapidly in recent years, the reasons why we proposed a new system were lack of an intelligent location-based...

Aiming at the problems of slow transmission speed and high hardware resources in the traditional USB data transmission system, a USB3.0 data transmission system based on FPGA is designed. The system uses FPGA as the core control chip, and EZ-USB FX3 realizes high-speed data transmission of USB3.0 synchronous...

According to the problem that the original tester is big, heavy and expensive, using a virtual operation interface instead of actual operation panel and substituting a simple RS232 to USB converter for a big circuit box, make the tester be more portable and convenient operation. After practical application,...

Electronic compass is a kind of absolute sensor that can measure the azimuth by use of the earth's magnetic field. Electronic compass is widely applied in mobile robot autonomous navigation. An electronic compass applied to a certain kind of out-door mobile robot is introduced in this paper. Data format...

Mechatronics is an immerging branch in the present era which deals with mechanical systems, instrumentations and electronic systems. Hydraulic and Pneumatic systems are the vital elements of Mechatronics system. The actuation of hydraulic and pneumatic system can be done using a PLC or a microcontroller....

This paper presents a design of softdog based on FPGA and describes hardware and software design. PC applies the CP2103 to transfers data via the USB to the FPGA device without modifying the application. The SPARTAN XC2S200 FPGA is the core of the softdog. It completes acquiring, processing and sending...

With more attention going to security of hotels, an effective hotel monitoring system was required. Based on the Samsung S3C2440, the proposed system uses the Linux system to accomplish the intelligent video surveillance.
