Recently mobile phones have become an essential tool for human communication. As more people use mobile phones, various services based on mobile phone networks and highend devices have been developed. Smartphone which integrates the functions of personal digital assistant and mobile phone obtains world-wide reputation as new personal business assistant and entertainment equipment because it is ...

Semi-active control devices, also called “Intelligent” control devices, constitute the positive aspects of both the passive and active control devices. A semi-active control strategy is similar to the active control strategy, but this control device has been shown to be more energy-efficient than active devices. A particular type of semi-active control device, the Variable Stiffness Device (VSD...

Pervasive or ubiquitous computing systems consist of large numbers of ‘invisible’ computers embedded into the environment which may interact with mobile users or form intelligent networks for sensing environmental conditions. Users will experience this world through a wide variety of devices, some they will wear (e.g medical monitoring systems), some they will carry (e.g. personal communicators...

Nowadays, all kinds of smart devices have been networked together and communicated with each other, thereby become an intelligent environment where interaction with the computing devices has become necessity and it happens anywhere anytime. For that reason, human-computer interaction (HCI) has been a lively field of research in the last few years. The aim of HCI research is to provide natural i...

In the study of intelligent space oriented to home service robot, an important technology is how to construct an communication network which has the characters of high reliability and easy building. In this paper, based on the characteristics of ZigBee protocol, ZigBee technology is used to construct a wireless sensor and actor network. Several intelligent services based on ZigBee wireless sens...
