In the present study, ultra‐wide band antenna attachable on unmanned aerial vehicle (UAV) surfaces usable as signal detection antenna in various bands was designed, and the practicality of the developed antenna was verified by attaching the antenna to a UAV and measuring the performance. The antenna suggested in this article was manufactured by forming a hemispheric conductor having the shape of a...
Compared with the traditional contact ranging technology, the optic-electronic ranging technology has been widely used in the fields of automatic measurement and online monitoring because of its non-contacting mode, good accuracy, real-time and other prominent advantages. Aiming at the engineering requirements of the close quarters ranging, the paper designed an optic-electronic ranging system for...
In next generation of wireless mobile communications, it is demanded that users could visit Internet services through any kind of radio access technology. Monitoring of radio access network (RAN) is very important for reconfigurable terminals (RT) in Mobile Internet. It is the foundation of network cooperation and seamless access for user services. In this paper, a new RAN monitoring scheme based...
Embedded systems normally have a large number of simple peripherals or circuits. These peripherals do not need to use complex protocols to connect with CPU. Therefore, modern embedded system provides some general-purpose Input/Output ( GPIO) pins that can be configured as either inputs or outputs. For debugging the embedded systems, users could input or output some simple commands with GPIO pins and...
Mobile Internet should provide pervasive services anywhere, anytime, and in numerous ways. Therefore, it is demanded that users could visit Internet services through any kind of radio access technology. Context awareness for multi-mode mobile terminals (MMT) in Mobile Internet is very important in next generation wireless mobile communications. It is the foundation of network co-operation and seamless...
DS-CDMA in the modern civil and military communications is widely used. Due to its low power spectral density, the DS-CDMA signal always floods in the background noise, bringing difficulties to the signalpsilas reconnaissance. Therefore, DS-CDMA signal detection has attracted attention of researchers. Because the fourth-order moment chip is blind to the arbitrary Gaussian noise, the detection method...
Wavelet analysis is becoming a useful tool because it allows the decomposition of data functions into different frequency or scale components. Accordingly wavelet transforms are to be suited to analyze short-timed high-frequency phenomena. The remarkable ability of wavelets to highlight the singularities associated with shocks present in the ship pitch field is explored. In the detection of ship pitch...
More and more miniature medical devices (MMD), such as alimentary canal miniature drug delivering device, wireless endoscope, feeding tubes and treatment probes, have been researched and developed for clinical diagnosis and therapy. When a MMD was put into the human body for diagnosis and therapy, it is necessary to provide a non-invasive locating method that can locate the MMD in long-term. Here,...
Motor task experiments play an essential role in exploring the brain mechanisms of movement control, and visual force-feedback is an important factor in these motor experiments. In this paper, the authors proposed a visual force-feedback system suitable for neuroscience experiment. With this system, the force output produced by participants can be detected and recorded in real time, while force output...
