20090019498 | METHOD AND SYSTEM FOR GENERATING SPECIFIC SEGMENTS OF A PROGRAM - The present invention provides a method for creating a specific segment during broadcasting program. Firstly, sending a program to an user terminal; then receiving a request of an user from the user terminal, which requests to create a specific segment, wherein the specific segment is part of the broadcasting program; finally creating the specific segment according to the request. Furthermore, the invention can also send the created specific segment to the user terminal. The invention solves the problem that the choice standard for the specific segment specified by the broadcasting program supplier/the program producer does not meet the real requirement of the users, thereby the users can obtain their required specific segments during watching program to satisfy their individual needs. | 01-15-2009 |

With present invention, on the premise that the communication capacity and power energy of sensor nodes are limited in a wireless sensor network, it is capable of efficiently utilize the network resource, save the power consumption of sensor node, and prolong the whole life of sensor network. | 07-23-2009 |
20100039940 | SENSOR NETWORK - The present invention provides a method for finding a backup node for a node in a sensor network. Firstly, determining a node which is in a state of waiting for being an agent node among a plurality of nodes adjacent to the node to be backed up for using the agent node to find the backup node. The states of waiting for being backed up is that the quantity of electricity of the node to be backed up drops below a preset value. According to the present invention, the node to be backed up does not need to communicate with a large number of nodes. It only needs to determine an agent node among the adjacent notes to do the substantial search for a backup node. | 02-18-2010 |
20100121226 | FALL DETECTION SYSTEM - The invention relates to a fall detection system, for detecting human fall incidents. The detection system comprises a sensor module to be worn by a user, for collecting motion data of his body, for instance acceleration data; first evaluation logic for identifying a potential fall incident on the basis of an impact observed in the acceleration data; and second evaluation logic for verifying that the sensor module is actually worn by the user, at least around the time of said impact, to prevent the system from raising an alarm if only the sensor module has fallen. The second evaluation logic may comprise free fall detection means for evaluating the acceleration data on characteristics which are typical for a free falling object, such as one or more full rotation and/or a free falling phase, during which the magnitude of the acceleration data is relatively stable and small. Additionally or alternatively the second evaluation logic may comprise body proximity detection means for detecting whether the sensor module is in close proximity to the human body. | 05-13-2010 |

20120029392 | METHOD AND SYSTEM FOR DETECTING A FALL OF A USER - This invention relates to a system and method for detecting a fall of a user. The system comprises at least one sensor, a determining unit and a processor. The at least one sensor worn on the body of the user generates sensor data relating to the fall, and the determining unit determines a sensor position of the at least one sensor. The processor adjusts the fall detection algorithm according to the sensor position, and performs an analysis based on the sensor data to determine whether a fall is occurring or not. In this way, fall detection is performed with high detection accuracy even if the sensor position changes, and the user feels good by wearing the sensors in their preferred way. | 02-02-2012 |
20120065925 | Methods and Apparatus for Detecting A Fall of User - This invention relates to methods and apparatus for detecting a fall of a user, especially to methods and apparatus for detecting a fall of a user by using pressure sensors. This invention discloses an apparatus for detecting a fall of a user, and the apparatus comprises first and second pressure sensors configured to obtain first and second data values of atmosphere pressure and intended to be worn on the body of the user, and a processor configured to derive a third data value of atmosphere pressure for determining whether a fall occurs or not from the first and second data values of atmosphere pressure. The first and second pressure sensors are configured in a way such that preset orientations of the first and second pressure sensors are opposite to each other. In this way, the weight of measuring elements comprised in the first and second pressure sensors have opposite effects on the measured atmosphere pressure, and thus (?) the measurement error caused by pressure sensor orientation variation can be reduced or even eliminated. | 03-15-2012 |
