20090106045 | SYSTEM AND METHOD OF TRANSMITTING EMERGENCY CONDITION USING WIRELESS SENSOR NETWORK - The present invention relates to a system and method of transmitting an emergency condition using a wireless sensor network that transmits a user's emergency condition using a wireless sensor network. A wireless sensor network communication device integrated with a biological sensor is attached to a user's body in order to gather user's biological information, and transmits the user's biological information through the wireless sensor network. A repeater receives the biological information from the communication device, and sends the received biological information by using a routing protocol of the wireless sensor network. A management server receives the biological information through the repeater, analyzes the biological information, and transmits a warning signal to a user or takes emergency measures. Therefore, it is possible to detect and cope with sudden physical problems, which are generated during user's exercises and outdoor activities, at an early stage. As a result, it is possible to significantly contribute to the prevention and reduction of danger for the weak and the elderly, and a user who is to be taken care of. | 04-23-2009 |
20090109058 | Traffic information providing method and device and traffic information receiving method and device - The traffic information providing device receives traffic information corresponding to a bus stop or a platform at which the traffic information providing device is positioned from a management server for collecting traffic information from at least one public transportation means, and broadcasts the received traffic information to the traffic information receiving device that is provided within a predetermined distance from the traffic information providing device by using the ZigBee or wireless sensor network that is a wireless personal area network (WPAN). The traffic information receiving device receives traffic information from the traffic information providing device by using the ZigBee or wireless sensor network, filters the same according to a filtering condition input by the user, and outputs traffic information desired by the user. | 04-30-2009 |
20100162224 | NODE UPDATE SYSTEM USING VIRTUAL PARTITION TECHNIQUE AND CONTROL METHOD THEREOF - Provided are a node update system using virtual partition technique and a control method thereof. A storage region of a sensor node is divided into a non-updatable invariable region and an updatable variable region to be virtually generated according to an execution operation of the sensor node. The states of the sensor nodes are monitored, and an update request signal is transmitted to a corresponding sensor node when update is necessary. Execution image information is received, and the execution image information is stored in the variable region to update an execution image, according to a response signal to the update request signal. | 06-24-2010 |
