Landslides, of slip/cast type, dynamics are mainly characterised by a sudden solid to fluid transitioning during heavy rain events. This feature makes them rather difficult to predict and therefore remains a major threat to nearby populated valleys. This paper aims at developing a new predictive system which analyses field movements using sensors. The idea is to use a sensor network to instrument...
A healthcare monitoring system is designed which can be used in the hospitals to monitor people who need to an intensive care. This system can be implemented on many biological signals. ECG signal is selected for put in practice in this work. Since ECG signal is measured in mille volt, it needs to be amplified. Also it is a noisy signal, so it needs to be filtered. ECG acquisition part contains AD620...
The instrumentation of a building civil structures is a practice that enable the measurements of some variations on the structure's dynamics properties, these variations, if they were found, could have relation with some changes in the structure's stiffness matrix, which are associated with some possible structural damages that could happened after some seismic event can occur. In this paper we design...
An instrumented walker is an assistive device designed to assess the effects of upper-limb loading on gait characteristics. Such a device is used in conjunction with a motion analysis system, and electromyography (EMG) (i.e., muscle electrical activity) to gain a complete assessment of the patient's gait patterns during clinical interventions. In this work we developed an instrumented wireless walker...
The designed system is a multi-point home security system, which uses the micro-controller AT89S52 as the core. The system mainly realizes the detection alarms of the multi-point home security based on the star networking of sensors, including position detection alarms and type detection alarms. The system also can display real-time time(Normal situation), alarm type and alarm time (when alarming)by...
In this paper, the system structure and Features of wireless sensor networks are introduced, visual Instrument and its advantages are introduced. A Wireless Sensing System Teaching Platform is constructed. It is a good platform and testing tools for sensor signals of real-time data acquisition, analysis, processing. This experiment platform can be used not only as a teaching experiment instrument,...
The sensor network testbeds available today rely on a communication channel different from the mote radio - a backchannel - to facilitate mote reprogramming, health monitoring and performance analysis. Such backchannels are either supported as wired communication channels (USB or Ethernet), or via an extra board coupled to the mote under test and thus introduce significant constraint on the testbed...
e-Science is one of the research hotspots in recent years, which focuses on how to apply IT on other disciplines. How to collect and transmit field data is an immediate problem should be solved in e-Science for those disciplines involving field observation. This paper brings out a system for field data collection and transmission in an automatic and high efficient way combined with several kinds of...
Heart rate, one of the most important physiological parameters to human body, is closely related to the function and status of the human heart. In order to display the heart rate in time in a convenient way and make sure the accuracy, this paper presents a project about the portable Bluetooth data sampler. The portable Bluetooth data sampler, with the help of the embedded heart rate sensor , Bluetooth...
A telemedicine system is described for monitoring the vital signs and general health indicators of patients with cardiac and diabetic conditions. Telemetry from wireless sensors and readings from other instruments are combined into a comprehensive patient health dataset. The data can be stored, accessed and displayed using mobile Internet communications with a server. The paper concentrates on the...
This paper presents a novel design, and prototype implementation, of a virtually transparent epidermal imagery (VTEI) system for laparo-endoscopic single-site (LESS) surgery. The system uses a network of multiple, micro wireless cameras and multiview mosaicing technique to obtain a panoramic view of the surgery area. This view provides visual feedback to surgeons with large viewing angles and areas...

In order to satisfy the family needs of ECG monitor, this article proposed a design scheme of ECG monitoring system based on wireless sensor network. It constructed a WSN (wireless sensor network) by sensor node and coordinator node. The ECG data was transmitted from sensor node to coordinator node. Then the data would be transmitted by serial interface to PC. To facilitate operation and observation...
A battery-powered, wireless alpha-ray sensor has been designed and realized using a high-resistivity-silicon BJT as radiation detector. Thanks to its excellent signal-to-noise ratio and intrinsic amplification, real-time alpha particle detection is possible using simple readout electronics which records alpha particle arrival time and charge spectrum.
In this paper a novel system to monitor warehouse with wireless sensor networks is proposed. The system consists of wireless nodes and monitor. Wireless sensor nodes collect temperature and humidity information and send to monitor. Monitor provides GUI for warehouse operators. The design of wireless nodes and monitor are introduced in detail.
In this paper,the existing architectures for underwater wireless sensor networks are introduced and their shortcomings are discussed. So we proposed a new architecture for underwater wireless sensor networks based on flexible loading platform. The detail of this new architecture is showed and two research challenges are outlined.
Sensor networks, by their very nature, are vulnerable to network security threats, with Denial of Service by radio jamming being one of the most common. It is more useful to detect jamming reactively than to proactively avoid it. We describe a method of countering jamming wherein some nodes just outside the jammed region form groups and transmit their locations to the Base Station for localization...
